Welcome back to the Energy Transition Digest!
Delegates at COP27 were warned that demand for critical materials could increase six-fold as the energy transition continues [1]. This week, the Digest is diving into a potential solution to meeting this steep increase in materials – creating a circular economy.
Let's get started.
Conserving Critical Materials
Much of the energy transition so far has depended on batteries as a clean energy source, leading to a significant demand increase for critical minerals such as lithium and cobalt. The International Energy Agency (IEA) predicts that a sixfold increase in demand for mineral inputs could see the market for Lithium growing to 40 times its current size. [2]
Meeting rising demand through traditional mining methods brings significant carbon emissions. However, not all hope is lost. Up to 95% of critical battery materials have the potential to be recycled[1], and there is no shortage of Lithium already on the market – it’s simply not being utilized. Millions of tonnes of necessary materials can currently be found in landfills, as electronics such as mobiles phones and laptops are disposed of at the end of their life[2]. Recycling is already being used to revamp smaller-scale IT equipment, and this will need to be scaled up to the wider industry. Utilizing existing materials at scale and repurposing them will allow the industry to meet demand without falling back on traditional, heavy-emitting methods.
Changing Priorities for the Transition
Pathways to carbon-free energy production have become clearer as renewable and green energy sources become cheaper and more accessible than ever. Therefore, some degree of transition focus is now shifting to tackling emissions created within the production process. The World Economic Forum predicts that materials used to produce vehicles will account for 60% of total vehicle emissions by 2040, by which time most transport is expected to be electrified [2]. This highlights a need to not just focus on clean energy sources but also address the raw materials being used for production. Industry simply can’t rely on clean energy sources to eliminate emissions – they must embed circular business practices throughout their supply chains.
Designing For a Circular Future
As the energy transition ramps up, growing numbers of renewable energy plants are being built alongside a wide range of brand-new infrastructure under construction. Physical assets such as these have a limited lifespan. The scale of potential waste these assets could produce is immense – a predicted 78 million tonnes of solar panels will be being decommissioned each year by 2050 [2]. It is vital that energy companies act now to build thoughtful circular design into all new assets. Designing new infrastructure to be easily disassembled and recommissioned will lower future demand for new materials, mitigating supply restraints alongside minimizing emissions. This isn’t just a theory – many companies are already baking circular design into their strategy. For example, Siemens Gamesa launched their fully recyclable wind turbine blade last year [5]. Aside from the clear sustainability benefits, designing for a circular economy presents great economic opportunity. PwC estimate that the recovery of raw materials from solar panels has the potential to create an opportunity worth $450m by just 2030[4].
At our Industry Transition 2022 conference in San Diego this September, Alexis Garcin , President & CEO of Michelin North America, demonstrated a practical commitment to circularity, as he noted that all Michelin tires will be "made exclusively from recycled or bio-based materials" by 2050, and that Michelin tires in 2022 already "have 53% renewable materials". LeHigh Technologies, acquired by Michelin in 2017, transform end-of-life tires into highly engineered MRP, a versatile raw material able to replace traditional oil based feedstock. This is just one example of circular business already underway.
Hard-to-Abates
What about industries with inherently linear business models? At first glance it may seem tricky to apply circular practices to much of the hard-to-abate industries. However, a circular economy can offer a solution to carbon reduction within these industries. Technologies such as Carbon Capture Utilization and Storage (CCUS) are being used to capture unavoidable emissions produced from traditional industry, such as cement production. This prevents emissions being released into the atmosphere and allows the CO2 to be utilized in industry. For example Twelve are transforming CO2 into chemicals, materials, and fuels at an industrial scale [6]. Creating partnerships across industry opens up the opportunity for a wider circular economy that doesn’t exclude traditional heavy industry.
Outlook
The concept of a circular economy is not a new, yet waste still appears to be embedded into all supply chains. More than 100 billion tons of resources flow into the economy every year, with over 60% of this ending up as waste or greenhouse gas emissions. In order to meet global decarbonization targets the time for industry to act is now. A circular economy can not be developed in a silo, but with cross-industry collaboration a profitable, carbon-neutral circular economy could be a transition game changer.
