Low-cost decarbonization of aluminum is enabled by renewable energy, which is now cheap, and getting cheaper. For the moment, aluminum smelters can procure clean power through a ''sleeved PPA'' (power purchase agreement), to virtually meet all their electricity needs.
Until renewable energy costs fall below $30/MWh globally and recycling systems achieve 85% efficiency, green aluminium''s market share will remain constrained to 8–10% of total output.
On the other hand, green aluminum energy storage offers a more economical approach. The cost of aluminum is relatively lower compared to lithium and cobalt, primarily due to its abundant availability in nature.
The 2022 Cost and Performance Assessment provides the levelized cost of storage (LCOS). The two metrics determine the average price that a unit of energy output would need to be sold at to cover all project costs inclusive of

But there are challenges, and such a contract has already seen some industry opposition. As pointed out by MetalMiner, a "green aluminum" contract spec would face several problems. First, having a standard calculation for what constitutes "green" or "low-carbon" could be problematic.
While lithium-ion has dominated energy storage conversations, aluminum battery energy storage power stations are emerging as the dark horse in the race for sustainable energy solutions.
With the growing demand for aluminum worldwide and the increased need to meet environmental benchmarks, green aluminum is becoming a viable investment, commanding a premium price.
There is not a benchmark price differential for green-power aluminium in the Chinese spot market, and the price differential is usually negotiated between suppliers and buyers on a case by case basis, sources told Fastmarkets.

Real-Time Price Data: Full-cycle data on metals pricing-including but not limited to copper, aluminum, and nickel-assists stakeholders in making their decisions.
Energy storage system costs for four-hour duration systems remain above $300/kWh, marking the first increase since 2017 due to rising raw material prices. Current fixed operation and maintenance costs for battery systems are estimated at 2.5% of capital costs.
If a buyer has an urgent need for green-power aluminium, or has a strict requirement for the material to be low carbon, the buyer needs to pay much higher premiums above ordinary aluminium prices, like 400-500 yuan ($56-70) per tonne; otherwise, the premiums can be around 100 yuan per tonne,” the third trader said.
With the certificate, green-power aluminium can be differentiated from those using thermal power, thus meeting demands of downstream producers who have special requirements for low-carbon raw materials.
China is still in the initial phase in the development of spot trading of green power aluminium compared with Europe and United States. In the next five to six years, market participants expect a more active spot market for this green material in China, with increasing demand from international and domestic downstream consumers.

Green primary aluminum is in increasing demand, and, as a result, aluminum products branded as “low-carbon” or “green” are starting to charge a premium price. Green alumina refers to aluminum produced using processes and technologies that leave a minimal environmental footprint.
Environmentally friendly aluminum is considered “green,” “super-green” or “ultra-green” primarily due to its production power source or proportion of recycled content. When aluminum producers rely primarily on a renewable energy source to produce the metal, it can be considered green aluminum.
