RECHARGE UK calls for new government to put renewed focus on skills

25th July 20245 Minutes

Specifically, the group wants to see radical changes to skills and training courses across the UK.

This builds upon recommendations set out in the group’s report ‘Harnessing the skills opportunities of a recharged electric vehicle sector’ which explores how the UK can equip its workforce for the exciting opportunities emerging in the EV sector.

RECHARGE UK is the EV arm of the REA (Association for Renewable Energy and Clean Technology). The report was produced in association with Curzon Consulting.

Ahead of the General Election, Labour said it would provide Technical Excellence Colleges which would work with businesses, trade unions and local government to provide young people with better job opportunities and the highly trained workforce local communities need in this changing world.

The government has now confirmed that it will establish a body to be known as Skills England, and reform the Apprenticeship Levy.

A briefing document states that Skills England will ‘bring together businesses, providers, unions, mayoral combined authorities and government to ensure we have the highly trained workforce that England needs’.

RECHARGE UK’s report calls for Centres of Excellence for Net Zero Skills which would see local employers sponsor courses at these sites, located in existing colleges and schools in the heart of communities. Providing additional funding, and resources to these education establishments. It would provide a clear and obvious pathway for post 19 education, where college and university graduates could specialise in net zero skills such as chargepoint installation and maintenance.

The REA’s Transport Policy Manager Matthew Adams said

We welcome the engagement Labour had with our skills report when they were in opposition. I hope that we can continue to have a strong relationship to deliver the change the industry needs to accelerate the deployment of charging infrastructure across the UK. The launch this week of Skills England prioritising the skills the UK needs going forward is a good start and I hope takes on some of our recommendations and recognises the challenges for each part of the EV sector from manufacturers, to installers and charge point operators (CPOs) to software providers and local authorities and technicians.

The Climate Change Committee (CCC) estimate that by 2030, between 80,000- 100,000 jobs[1] could be created by electric vehicle and battery manufacturing in the UK. Meanwhile we are seeing a decline in the number of people qualified to operate and install electrical machinery. Since 2018 the number of people with electro technical skills has fallen by 19% from 342,000 in 2018/19 to 276,000 ± 10,000 in 2023[2]. 

Research by Curzon Consulting for RECHARGE UK’s report offers a unique insight into current and future recruitment concerns by charge point operators (CPOs). Of those CPOs interviewed by Curzon, 75% of CPOs expressed the view that the current skills gap was “significant” to “very significant”. Recruitment is predominantly from outside the EV industry and 25% of CPOs stated that it took them two months to fill vacancies, with 42% experiencing a lag of three months or longer to fill EV electrician roles.

Almost 40% of those surveyed also said that skills shortages were impacted by Geography. This highlights that a full national strategy like a Centres for Excellence programme could be beneficial in addressing the growing demand for electrical skills across the country.

Most pressingly all CPOs surveyed said that demand for electricians would rise significantly in future and 48% said that demand would rise beyond what the current workforce could support.

Natalia Sokolova, Partner, Curzon Consulting, commented:

With the establishment of Skills England and the reform of the Apprenticeship Levy, we are setting the stage to bring together businesses, providers, unions, and government bodies to build a highly trained workforce. Our research evidences that we must go even further to create Centres of Excellence for Net Zero Skills. The time to act is now

Concerns & opportunities: Harnessing the skills opportunities of a recharged electric vehicle sector

8th May 20243 Minutes

The recent RECHARGE UK report on ‘Harnessing the skills opportunities of a recharged electric vehicle sector’, in association with Curzon Consulting, explores how the UK can equip its workforce for the exciting opportunities emerging in the EV sector.

It’s clear from the research that various concerns are prevalent across multiple stakeholders.

The number one concern for all participants is attaining and maintaining a capable, skilled workforce. Cited through various frustrations in workforce shortages, EV skills gaps and funding. 

DNOs, CPOs & Tech-Safe accredited organisations all struggle to recruit electricians with the relevant EV experience. Many indicate the existing workforce does not have the specific knowledge required to maintain the EV sector or the capability to meet the future demands of the industry, with little time to retrain.

Forecasts predict a shortage of qualified technicians to service the growing number of electric vehicles. Skilled EV personnel are often lured by large contracts and concentrated in urban areas, leaving a limited talent pool for smaller organisations in rural communities.

Similarly, Local Authorities, especially those in rural areas, work hard to attract qualified staff for EV infrastructure projects. With limited, temporary funding, they lack the budget to hire & retain experienced staff.

Vehicle Manufacturers are concerned about recruiting staff across the entire EV design & manufacturing process. Reskilling the existing workforce will be an expensive challenge, with many traditional mechanic roles disappearing to be replaced by the shift to electric.

Software Providers have similar recruitment challenges, with software development courses too focused on marketing applications and not enough on practical engineering applications.

For those with specialised EV skills, sourcing and attracting qualified professionals is demanding due to low unemployment and high competition within the software development field.

However, it’s not all doom & gloom… the report made four recommendations to ensure the EV sector can compete globally and meet the stakeholder concerns.

As expected, the EV sector offers significant, job & career opportunities, for a diverse workforce, across the entire sector. However, a reform in education is required to ensure qualified, and capable individuals meet the needs of the industry.

Upskilling and retraining to support the continued improvement and promotion of opportunities to the existing workforce and reskilling programmes, to ensure that those in the workforce without relevant skills, outside of the EV sector can access the growing number of opportunities on offer.

However, for the sector to meet the demands, these recommendations require collaboration between the Government, the EV industry, and the Education sector.

Can charging supply keep pace with electric vehicle demand?

11 Minutes

Net-zero carbon emissions by 2050…

Electric vehicles (EVs) are increasingly heralded by nations across the globe as a vital part of the net-zero transition to reduce emissions, and the key technology for decarbonising transportation, which accounts for 13% of emissions globally. But whilst vehicle sales have been booming in recent years, the installation of charging networks that underpin EV usage are trailing dangerously behind. The extent of this lag is particularly concerning in the United Kingdom (UK) where it poses a fundamental threat not just to the continued growth of the EV market, which by the end of 2023 is projected to be worth £16bn, but it threatens any plans for the UK to reach net zero carbon emissions by 2050.

A global EV boom driven by three central influences

Such has been the drive to increase the uptake of EVs, that global sales of Battery EVs (BEVs) and Plug-In Hybrid EVs (PHEV) doubled in 2021 from the previous year, and 2022 saw a +55% increase in global EV sales over ‘21. The registration of 10.5 million new vehicles in ’22 was despite component supply chain shortages and disruptions from the war in Ukraine that hampered output. With approximately 27 million EVs on the road today, they now account for a global market share of 13% of vehicles on the road.

What is clear is that as global consumers increasingly align their climate-driven values with vehicle purchasing, the number of EVs on the road will continue to rise exponentially. This is an ‘EV boom’ that has been accelerated by a combination of three central influences:

  1. Sustained governmental policy support, in the form of subsidies and incentives, pledges to phase out internal combustion engines (ICEs), and lofty electrification targets
  2. The rise in the availability and performance of EV models, which now gives consumers five times as many to choose from than in 2015
  3. Electrification of fleets by car manufacturers, in a race to meet rising consumer demand.

Showcasing the innovations and ideas behind EV market growth

The annual London EV show and conference, held at the end of November ‘22, is a platform where stakeholders from all three market influences gather to showcase the innovations and ideas that are spearheading the UK EV transition. With representation from the entire value chain, this year’s event included collaborations between government representatives, fleet management, charging systems & solutions providers, battery technology providers, major car manufacturers, and other influential stakeholders.

Attending the show provided me with a ‘peak-under-the-bonnet’ of the UK EV market and shed light on some of the key trends emerging in 2023 and beyond. Conference talks included those from industry leaders and leading research centres, amongst the latest vehicle innovations being showcased. These talks had one key common theme – that whilst a marketplace as dynamic as EVs offers great opportunity, commercially and in tackling climate change, capitalising effectively on these opportunities over the next few years will be fraught with challenge for the UK.

UK charging infrastructure is struggling to keep pace with the EV growth

The London EV show highlighted just how much the UK EV market has expanded in recent years in line with global growth, notching up an impressive 92% increase in EV registrations between January ‘21 and January ‘22.

UK charging, however, is still in its infancy relative to the vehicles it powers, and comparatively lags behind. There is a growing disparity between the growth rates of EV sales in the UK and charge point installations. This divergence threatens to impede the UK from meeting climate-goals set by the government and derail the feasibility of the UK’s ban on internal combustion engines (ICEs) that looms in 2030.

When you compare the absolute number of public charge point installations the UK needs to support the proposed transition, with current figures, it is clear there is still a long way to go. If the government’s 2022 charging infrastructure strategy successfully meets its ambition, by 2030 there should be over 300,000 public chargers installed nationwide. In comparison, as of January ‘23, there were cumulatively just 38,000 public charge points available across the UK.

More importantly, though, is considering the pace of charger installations relative to new EV registrations – which is slowing owing to the continued acceleration of new EV registrations. Since January ‘20, the cumulative number of EVs in the UK has increased 3.8X, whereas the number of charge points has increased just 2.6X. This increasing disparity is made ever clearer by the change in the UK’s EV-to-charge point ratio – a measure which helps assess the suitability of a nation’s charging network to support its vehicle’s needs.

As a benchmark, the Alternative Fuel Infrastructure Directive (AFID), an EU policy which regulates the deployment of public chargers, recommends a ratio of 10 EVs per public charge point for EU member states.

In 2016, the UK had a healthy ratio of approximately 8 EVs per charge point. Comparatively, the UK now has the 9th worst global ratio of 21 EVs per public charge point. There are evidently key lessons to be learned from the likes of South Korea, the global leader which boasts a ratio of just 2.6.

Unlocking mass adoption with public charging infrastructure

The vehicle-to-charger gap poses a fundamental problem to the mass adoption of EVs in the UK, for two main reasons. Firstly, on average, 30% of UK households lack off-street parking for residential charging. This figure rises to around 40% across major UK cities, and as high as 50% in London. These households will therefore have to rely on the public charging network – either off-street slow, charging, or nearby fast/rapid charging hubs – to charge their vehicles at home.

This scenario works, provided there are enough charge points to accommodate users. However, too few chargers pose a major barrier for drivers switching over from ICEs, who will view EVs as impractical until there is somewhere suitably convenient to charge them.

When Which? surveyed 1.5k electric car owners, nearly half said that their nearest public chargers were over a 20-minute walk away.

Not exactly convenient.

The logic is the same looking across the UK’s charging network for longer journeys. For true mass adoption, there needs to be enough charge points to make charging your vehicle battery as convenient as filling up with fuel currently.

Speak to any EV owner in the UK, however, and they will tell you of the growing issues around public charging: long queues, a myriad of payment systems and apps to contend with for different charge-point-operators, and chargers which simply don’t work (experienced by 4 in 10 customers of public EV chargers).

This is not conducive to convincing the masses to switch from ICE vehicles to the more sustainable option of electric.

These issues with the charging infrastructure will continue to exacerbate as drivers become increasingly reliant on public chargers, versus at home or work, the more that make the switch to EVs. The UK urgently needs to accelerate its plans for large-scale installations across the public charging network, which is so far failing to deliver the c.100 installations per day needed until 2030 – last month (Jan ’23) just 28 charging devices were installed per day. A large-scale programme such as this requires a unified drive from all stakeholders.

As demand and supply continue to fall out of balance, this situation presents opportunities for private investment in the expansion of the charging networks. The current EV charge point operator market is highly fragmented and lacks a ‘gold-standard’ of consumer vehicle charging. There is a clear market need that so far appears unfulfilled in both availability and quality.

Whilst there are a multitude of other challenges that must be addressed, such as ensuring a sufficient supply of electricity to meet charging demands, each of these challenges offers their own commercial opportunities. 

For those considering entering or expanding within the space, now is the time to answer the key strategic questions – what is the ‘Size of the Prize’ available? Which of the current barriers-to-adoption offer the greatest opportunities if addressed effectively, and how can that value be harnessed?

Sustainable Construction Innovation, Does it matter?

8th September 20222 Minutes

The transport construction industry has significant opportunities to reduce carbon by developing materials with lower embedded carbon. Producing cement uses a great deal of energy, so finding a waste product that can substitute for cement makes good environmental sense, while concrete is always at the top of construction sites carbon emissions. Pulverised Fuel Ash, PFA, is a by-product of coal-burning power stations. The ‘ash’ is recovered from the gases and used, amongst other functions, as a cement substitute. This will reduce CO2 by reducing cement through the increased use of cement replacement and increased use of recycled aggregate. 

This positive change is one of the most common ways that businesses innovate, and one used to innovate frequently. Cement product innovations play a significant role in the transition towards carbon net-zero emissions across construction industries. 

The network of universities, cCatapults, and grant funding allows businesses to embrace innovation and provide more high-value services that change the industry’s innovation capability. There is unprecedented investment and attention by Government, customers and business to advance innovation capability to deliver new business outcomes that will redefine collaborative relationships across the supply chain, increase repeat business with customers and demonstrate that the industry is not a commodity and cannot be procured solely on price. What is delivered is complex and requires highly skilled people to look at delivering the best solution.

Which risks are the most challenging to carbon net-zero in Africa?

8th September 20222 Minutes

There is a ‘ ticking timebomb’ in third-world countries where there is heavy reliance on fossil fuels (coal burning) for electricity and is responsible for between thirty to/forty per cent of employment. In the particular case of Africa, tThe continent is embarking on a massive expansion of fossil fuel electricity. More than 200 new power stations are planned, the majority of which will burn coal (Pollutionwatch, The Guardian). However, Africa is uniquely positioned to leapfrog dependence on fossil fuels and utilise abundant renewable resources such as solar and wind. Government legislation to reduce this dependency would see joblessness leading to hunger, civil unrest and a potential change of government at the ballot box. Trade Unions are very strong in these sectors due to human rights abuses for tens of years. For change to happen, there is a tricky hierarchy of political players to be satisfied and included before any legislation would be agreed and implemented. 
 
What business opportunities could be related to the African net-zero transition? 
 
Many of the countries mentioned above have very high temperatures, which provide strong sunlight. This raises solar panel opportunities. The countries are also vast and tempting medium-term investment options for wind turbines as their manufacturing costs drop and returns increase as populations grow and require electrification. Fossil fuel companies need to start investing in renewable energies to continue making positive revenue margins and balancing their emissions to carbon net-zero. 
 
Social or economic network effects? 
 
There are extreme views against fossil fuel companies, often with headquarters in European countries. Social media highlights these emission concerns and provides a platform to disseminate important emission information and gather people to attend anti-emissions rallies.

Why renewable energy is fuelling investor interest?

8th September 20221 Minutes

Renewables will represent 80% of the total share of investments in power generating capacity from today to 2050. Global energy needs are expected to grow by 30% between today and 2040. 

As an asset class, renewable energy has matured dramatically over the past two decades. It has gone from being seen as an alternative culture to having huge investment potential. At the same time, traditional investment norms are changing and not just because of the evolving sustainability mega-trend. In recent years, investment managers have increased their allocations to the broader real assets sector with growing numbers classifying infrastructure and real estate as “real assets”. 

Solar power does not pollute the air with greenhouse gases and is noise-free to be used for residential purposes. Solar opportunities are available at various scales, i.e. for households and large business ventures providing power to the grid. Solar panels are the fastest-growing renewable energy option, thanks to falling costs and increasing investment. Their easy installation and “low emissions” are environmentally friendly. 

Wind turbine power will be an increasingly compelling longer-term investment due to increasing urbanisation and population growth, leading to higher electricity demand. Technological progress with relative cost advantages for renewable energies and an improved regulatory environment (social and political support) motivates businesses to manufacture wind turbines.

Why Coupling your Business Plan With Your Decarbonisation Plan is More Effective Than Drafting Them Separately?

8th September 20221 Minutes

There are incredible synergies with aligning purpose and ambition in the decarbonisation sense to the Mission, Vision and Values of the business. Thinking of them in unison will intertwine the business plan (revenue generation) with the decarbonisation plan and allow the business to set short and long-term business goals and decarbonisation metrics. As with most strategy plans, the goals/metrics should be reviewed bi-annually to correct any deviations from the plan.

In the government highway infrastructure sector, the business is aligned to decarbonisation 2050 as legislated by the Paris Agreement 2015 with 2030, 2040 and 2050 time horizons to achieve scientifically based metrics. Collaboration with delivery partners is crucial in reaching these targets. Targets for the delivery partners are aligned to ensuring achieving the business’s Scope 1,2 and 3 targets.

Innovation and collaboration are driving decarbonised materials, electric fleets and whole life design thinking. In other words, it directs a circular economy. Proven technologies and close ties to the government encourage policymakers to be bolder with the legislation they advise politicians to implement. With proven technologies being implemented, financiers are more willing to provide financing.

These innovations provide people who live around major highways with cleaner air and reduced pollution. Less pollution means fewer lung inflictions which ultimately means a healthier society and reduced pressure on the NHS.

Is Degrowth and Decoupling The Answer to Sustainability?

8th September 20222 Minutes

There is little evidence that greenhouse gas emissions can be decoupled from economic growth in absolute terms from an environmental perspective. Since economic growth is one of the main drivers for rising emissions (and increasing depletion of non-renewable resources), it seems evident that a transition to degrowth would make an essential contribution to climate change mitigation, and hence to our moral obligation to preserve future generations’ rights to basic needs fulfilment.

GDP ultimately cannot be decoupled from material and energy use growth. It is, therefore, misleading to develop a growth-oriented policy around the expectation that decoupling is possible. We also note that GDP is increasingly seen as a poor substitution for societal wellbeing. GDP growth is, therefore, a questionable societal goal. Society can sustainably improve wellbeing, including the wellbeing of its natural assets, but only by discarding GDP growth as the goal favouring more comprehensive measures of societal wellbeing.

While relative decoupling has been observed in multiple countries, absolute decoupling remains elusive. Studies observe that no country has achieved absolute decoupling during the past 50 years. Another study reports that population growth and increases in affluence are overwhelming efficiency improvements at the global scale. There is no evidence for absolute reductions in environmental impacts and little evidence to date, even for significant relative decoupling.  

Technological advances can lead to absolute decoupling for specific types of impact. For example, it is possible to envisage a scenario in which GDP growth is decoupled from using fossil fuels and related CO2 emissions by switching to 100% renewable energy.

Carbon net zero consensus vs the circular economy

16 Minutes

Two core concepts behind carbon net-zero (CN0) are carbon reduction, which focuses on lowering negative greenhouse gas (GHG) emissions, and carbon offsetting, where negative emissions are counterbalanced through activity and investments that theoretically net-off their impact.

Policy and public consensus leave the impression that achieving ‘carbon neutrality’ or CN0 through this reduction and offsetting is the one (or two) stop-shop solution to addressing the world’s climate change and sustainability challenges. Perhaps a bit more constructive challenge to this consensus is required.

Up in the trees

The majority of carbon offsetting is conducted through reforestation or afforestation. There are other more esoteric activities such as targeted investments in developing nations that facilitate reduced GHG emissions, e.g. gifting fuel-efficient stoves to specific communities. However, at present there is particularly limited agreement on the timing of offsetting activities; organisations can theoretically report outcomes years ahead of their implementation.

A guessing-game

Whilst meaningful calculations of CO2e emissions are plausible, arguably the calculation of carbon offset is a guessing game. Using reforestation and afforestation as examples: The lack of scientific consensus on the calculation of carbon capture, the finite lifetime of trees, failure to account for existing flora being displaced by trees being planted, the global-warming impact of light absorption by dark forests (especially in previously white, tundra regions) and the insulating impact of organic aerosols released by trees all serve as strong challenges to the generally accepted carbon-capture benefits.

The organisations promoting empirically precise carbon offsetting activities are inevitably motivated to deliver the most significant carbon-capture for a given cost, often driving them to plant fast-growing trees to generate the speediest carbon sinks. Studies, however, have shown that rapid tree growth directly correlates with short life-span, after which the dead tree is either decomposed naturally or burned. This releases the “captured” CO2 and accelerates the point at which carbon capture is permanently reversed. Careless tree-species selection creates further challenges around habitat preservation, for both flora and fauna, with major knock-on consequences for local ecosystems.

Even more fundamentally, the term CO2e may acknowledge the net warming effects of GHGs, but when it comes to carbon capture, it risks oversimplification. Photosynthesis captures CO2, but the remaining GHG groups including nitrous oxides, hydrofluorocarbons and chlorofluorocarbons are not part of the equation; they continue being generated and released unabated and ignored.

It’s all about timing

There are various accounting methods for assessing the impact of timing with respect to money: Discounted Cash Flow, Net Present Value and Internal Rate of Return, are calculations that recognise the importance of timing in financial decision-making. No such calculations exist for carbon offset: Organisations can produce GHGs today, and have a ten-year-plus plan for when these will be offset, without addressing the damage or reduced benefit of the delay. The urgency of action on sustainability is unquestionable, acknowledged but still not fully understood.

Regressive macro-behaviours

The prevalence of the CN0, Sustainability and ESG agenda certainly highlights a widely shared intention. However, albeit perhaps being deliberately extreme in reference points, some of the large-scale actions being marketed highlight branding exercises that deflect from the critical need for more fundamental change in our approach.

Take the whole concept of carbon credits as an example? It can be humorously (and dramatically) argued that these are reminiscent of the medieval Catholic practice of selling “indulgences”; a financial penalty to reduce the religious penance required by heaven for forgiveness. The wealthier you were, the lesser the repercussions for sinning!

However, their regressive macro-behaviours are no laughing matter. Reforestation for example typically takes place ‘behind closed-doors’ and this can have disastrous results. Since 2009, the Kenya Forest Service, backed by EU funding for reforestation, has been forcibly removing and dispossessing the Sengwer people of the Embobut Forest, burning more than 1500 homes in the process, and killing one Sengwer man. This humanitarian disaster, highlights just one facet of the overlooked, problematic underbelly of our approach to CN0.

The BBC and Greenpeace have run articles highlighting the level of waste being exported to Turkey, with estimates of 40% of UK plastic ending up there. In theory, this plastic is exported to be recycled, but the reality is that once those responsible have pocketed their payment, it is simply dumped. Simplistic recycling targets, and an acceptance of devolving accountability is at the root cause of these issues: The National Audit Office was damning in its findings stating in July 2018 that “[The UK’s recycling system] appears to have evolved into a comfortable way for government to meet targets without facing up to the underlying recycling issues. The government has no evidence that the system has encouraged companies to minimise packaging or make it easy to recycle. And it relies on exporting materials to other parts of the world without adequate checks to ensure this material is actually recycled, and without consideration of whether other countries will continue to accept it in the long term.”

Carbon offsetting opportunities are a finite resource

There is a limit to how much reforestation and afforestation can be conducted, both in terms of absolute capacity, or more challengingly, due to financial constraints. The largest and longest-lived type of commercially grown fauna is fruit trees (the largest major group being cherry trees) which typically grow no more than 15m tall, whereas as an example, most pine species consistently grow to 50m or more. Broadly speaking, the taller the tree, the denser the carbon capture for a given area. What this means is that optimal carbon-sink solutions have severely limited meaningful commercial benefit so the land must be procured for offsetting projects, and maintained at cost.  At present, there are large swathes of suitable low-price land available, but as these options are exhausted by initial offsetting ventures future projects will have to procure land with commercial uses at much higher costs. Developed nations will likely purchase the majority if not all of the cheap land, leaving developing nations with few or no options available.

Used cooking oil is commonly re-purposed in the UK, burned as biodiesel in lorries, which once again, in isolation is a positive step. However, such is that the appetite for cooking oil derived biodiesel in the UK, that businesses have begun importing it from overseas. Burning marine diesel to transport cooking oil to be burned as biodiesel (which still emits GHGs) all to save on lorry diesel usage? This has a net detrimental environmental effect compared to burning biodiesel at or near its origin and raises obvious questions.

CN0: A single, over-simplified metric

Putting aside carbon off-setting practices, measuring CO2 emissions as the sole metric for success in the sustainability battle means that other negative consequences become fair game. Resource depletion, habitat destruction, loss of biodiversity, water pollution, water poverty and human suffering at times go unchecked.  There is particular cause for concern around “green” technologies with a focus on energy generation and energy storage.

  • Dependence on cobalt: At present, the highest energy-density commercially available batteries are lithium-ion (Li+) with cobalt-based cathodes and they form the mainstay of almost all consumer electronics where battery size and weight are critical selling points like phones and laptops. More than 55% of the world’s cobalt is mined in DR Congo, where Amnesty International estimate 40,000 child workers are at risk of contact dermatitis, Hard Metal Lung Disease, lethal mine collapses, atrocious working conditions and modern-day slavery.

  • Lithium remains a problem: Manufacturers of larger applications of Li+ batteries such as battery-electric cars, have more recently been moving away from cobalt cathodes, such as Tesla in September 2020, but the lithium remains problematic. Lithium is found in three forms in the earth’s crust; in solution (brine) and two mineral formats (pegmatite and sedimentary). Lithium brine forms the majority of global reserves, and is predominantly found in low purity form of 4-6% in deep aquifers (subterranean water reserves) often underneath unique salt-flat habitats. Lithium brine is pumped onto vast plastic sheets to evaporate the water and leave behind lithium salt deposits. Extraction of mineral forms means mining, whilst purification requires sulphuric acid, releasing atmospheric CO2. Modelling by LUT and Augsburg universities suggest earth will exhaust its lithium reserves between 2040 and 2100 dependent upon battery technologies, battery electric vehicle (BEV) manufacturing, lithium recycling and global population variables. This modelling assumes the appetite to destroy virtually all of the world’s largest salt-flat ecosystems.

  • Water: Water vapour is part of a positive environmental and atmospheric feedback loop. Unfortunately, due to some of the aforementioned CN0 related activities there are some serious ramifications for water on the horizon. Making full use of global lithium reserves requires (along with rock extraction) removal and evaporation of subterranean lithium brine. Much of this supply is in the form of nonmeteoric aquifers; meaning they are not replenished during the course of the hydrologic (water) cycle, instead consisting purely of water formed by geological events early in the earth’s history, from evaporated seas and volcanic activity. These supplies are not renewable. Further still, this removal and evaporation causes the water tables to drop in the associated surrounding areas which has a resulting detrimental effect on wildlife, farming, etc. Lithium brine is typically found beneath evaporated sea-beds which are almost exclusively located in deserts with no viable alternative water source.

  • Solar power comes at a price: At the core of solar-power (photovoltaic) technologies is high-purity silicon, extracted from quartz (silicon dioxide). Quartz is mined world-wide, with the greatest concentrations in developing nations, where labour conditions are poor and miners are exposed to carcinogenic respirable-sized quartz, responsible for the diseases silicosis and pulmonary fibrosis. Initial quartz purification requires heating with carbon (often using fossil-fuels) to 2000°C to remove the dioxide component, released as atmospheric CO2. Further purification uses hydrochloric acid, by-producing the incredibly toxic compound silicon tetrachloride, responsible for several environmental disasters in China. Construction of a large solar-power installation (200+ Megawatts) requires upwards of a billion litres of water, and can consume more than 20 million litres per year to keep it sufficiently clean.

  • Wind-farms: Wind-farm turbine-blades are typically constructed from varying combinations of glass-fibre, polyester, epoxy and carbon-fibre, the sourcing and processing of which involves significant quantities of volatile organic compounds a class of environmental pollutant compounds hazardous to human health. They have a designed lifespan typically of 25 – 30 years, with first-generation wind-turbines now being decommissioned. In March 2021, New Civil Engineer published an article highlighting the CO2 reduction initiative of re-purposing worn-out wind turbine blades in lieu of steel rebar for construction concrete. Definitely innovative and any diversion from landfill or reduction of carbon is a success. However, as well as being clear on the implication of down-cycling in this manner it is important to seize upon the opportunity to push further and scale such initiatives. For example, contrasting wind-farm turbine blades with other turbine blade types highlights the opportunity for a more holistic approach: Aviation propellers have planned life-cycles, defined by flying hours, and are designed with erosion-shields and sacrificial high-wear parts made of readily-recycled steel and aluminium replaced at scheduled intervals to keep the blades operational, and prolong the lifecycle of the core components.

What to do?

Carbon reducing activities are and must remain a key focus for all. BEVs, sustainable aviation fuel (SAF), biodiesel all make the headlines, and the public are provided with easily accessible solutions like re-usable shopping bags and recycling whilst it seems that the real difficult changes are yet to come.

Perhaps there is a need for a fundamental overhaul of sustainability reporting and metrics to offer real insight.
