The price of batteries is plummeting, it’s good news for the planet

For years, scientists have urged a shift from fossil fuels to renewable energy. Solar and wind are gaining traction, but their reliance on weather creates gaps in power generation. The answer? A surge in battery storage.

A recent International Energy Agency (IEA) report highlights the crucial role batteries will play in achieving global climate goals. Lower costs, driven by advancements in lithium-ion technology, are making renewable energy transitions more feasible. The report predicts a 40% price drop in batteries by 2030.

However, this burgeoning demand for electric vehicles and renewable energy necessitates even cheaper batteries in the coming years. The IEA estimates a six-fold increase in energy storage capacity by 2030.

“Meeting international energy and climate targets depends on rapidly scaling up batteries,” stated IEA Executive Director Fatih Birol. “Batteries are fundamentally changing the energy landscape.”

Lithium-ion batteries, once primarily associated with consumer electronics, are now powering the energy sector. In 2023, 90% of battery demand came from this sector, with the overall market size exploding tenfold in just eight years. Battery costs have plummeted by a staggering 90% in the past 15 years, the most significant price drop of any energy technology to date.

This translates to more affordable electric vehicles and solar energy, making them competitive with fossil fuels. “Solar PV (photovoltaic) combined with batteries is already cost-competitive with new coal plants in India,” Birol noted. “Within a few years, it’ll be cheaper than new coal in China and gas-fired power in the US.”

Despite these promising figures, the IEA warns that reaching the UN’s goal of tripling renewable energy capacity by 2030 may require a six-fold increase in global battery storage. This translates to an annual growth rate of at least 25% for battery storage deployment. Battery prices need to fall further while performance is maintained or improved.

The IEA anticipates that advancements in battery chemistry and manufacturing could slash lithium-ion costs globally by 40% by 2030. Additionally, battery manufacturing is currently concentrated in a few countries, needing diversification for future sustainability.

“A shortfall in battery deployment could stall clean energy transitions,” warns the report.

The Consumer Impact of Cheaper Batteries

The rise of electric vehicles and renewable energy is crucial for curbing emissions. While US EV adoption has slowed slightly, the global trend is positive. In 2023, EV deployment surged by 40%, adding 14 million vehicles to the road. The IEA estimates that by the end of the decade, the growing EV fleet could displace 8 million barrels of oil daily.

For consumers, lower battery costs translate to cheaper electric vehicles in the near future. Affordability is a major barrier for US drivers considering EVs. More affordable models, driven by falling battery prices, could entice more consumers to switch, potentially aiding the Biden Administration’s goal of 50% electric vehicle sales by 2030.

On the infrastructure side, cheaper energy storage allows developing nations to consider renewable power plants at prices comparable to fossil fuels. Falling battery prices also facilitate the deployment of renewable microgrids in underserved regions.

In countries like the US, a more reliable, battery-backed energy sector would enhance energy independence by reducing reliance on foreign fossil fuels. Renewable energy accounted for only 19% of the US grid in 2020, but affordable and reliable storage could change that. Stanford researchers even simulated a scenario where the US could maintain a 100% renewable energy grid by 2050.

The Challenge of Critical Minerals

The current battery boom has a critical mineral dependency. China alone processes over half the world’s lithium and cobalt. Mining these minerals can be dangerous and environmentally destructive.

New battery types could offer solutions. Lithium iron phosphate (LFP) batteries, increasingly used in EVs, utilize a different chemistry that excludes nickel and cobalt. While traditional lithium-ion batteries remain dominant, LFP accounted for 80% of new batteries produced in 2023. Additionally, more efficient recycling of aluminum, copper, and other resources from e-waste could potentially lead to less intensive battery production. Currently, less than 1% of rare earth metals from e-waste are recycled.

The battery boom offers a path towards a cleaner future, but significant challenges remain. Addressing the critical mineral dependency and increasing recycling rates are crucial steps towards a truly sustainable energy future.
