Dive Insight:

Lithium-ion batteries are the dominant technology used for energy storage today, but since the start of the war in Ukraine, the price of imported lithium has doubled, said MIT professor Yang Shao-Horn. It is “now the most expensive component” in lithium-ion batteries, he told conference attendees. Prices of other major metals also jumped.

“The sharp increase in the cost of lithium could potentially push other [storage] technologies and move them faster,” he said, pointing to sodium-ion battery chemistry as one example. The technology is “fast moving,” nearly matching the performance of lithium-ion batteries, at a cost that is expected to be “much lower,” said Shao-Horn.

President Biden highlighted the need for domestically sourced technology on March 31 when implementing the Defense Production Act to reduce reliance on foreign imports of key elements and metals used in grid battery storage and the soaring EV market. Biden’s move authorized the Department of Defense “to support the production and processing of minerals and materials used for large-capacity batteries” while ensuring “strong standards of environmental, labor, community and tribal consulting.”

“You can’t have high toxicity,” Thomas Winter, Fluence’s vice president of strategic technology, told the MIT audience,

“As costs fall, new technologies have opened up,” a trend that is expected to continue, Winter said. He stressed that domestic sourcing of battery elements and local battery manufacturing are key. If batteries are going to the US market, they have to come from the US, if used in Europe, they have to come from Europe, or if used in India, they have to come from India, Winter added.

Like Shao-Horn, Winter is also touting the promise of a sodium-ion battery. “Solid-state batteries are very attractive” because of their density and the fact that they are safer than lithium-ion, he said.

Another promising technology is metal-air chemistry, including iron-air.

If sodium and metal-air battery technologies become cost-competitive, they are superior to lithium-ion storage in that they are more stable with more than twice the lifespan — 25 years compared to lithium’s eight to 10 years, Lawrence Berkeley National Laboratory Senior Scientist and Divisional Director Robert Kostecki told Utility Dive.

Form Energy is developing a battery that uses iron, air, and water to create what it calls “reversible corrosion.” Expected to discharge for up to 100 hours, “the battery breathes oxygen from the air and turns ferrous metal into rust,” according to the company. It has been awarded a federal grant from the Department of Energy’s Advanced Research Projects Agency-Energy and the state of California. In late February, Form Energy signed an agreement with Georgia Power for a 15 MW/1,500 MWh storage project.

Scott Burger, Form Energy’s senior manager, said at the April 1 MIT conference session that the company was looking at ways to buy carbon-free iron. That includes powering production with renewable powered green hydrogen.

Burger estimates the cost of installing an iron-air battery will be under $20 kWh, which will help the technology compete with lithium-ion batteries as well as the gas-fired generation they will replace.

Other emerging storage technologies include electric vehicles with network-connected communications software that can supply power to electrical systems in times of stress. Another candidate is to reuse EV batteries which do not have enough capacity for driving needs but sufficient for energy storage.

As transportation systems become increasingly electrified, it represents the terawatt-hours of power that can be part of our power system, says MIT’s Shao-Horn.

Correction: Earlier versions of this story incorrectly identified the source of the federal grant for Form Energy. They came from the Department of Energy’s Advanced Research Projects Agency-Energy. Additionally, the article misquotes Fluence’s Thomas Winter, who uses the term solid-state battery instead of salt-state. We have corrected the quote.

What is equity resiliency?

This storage technology includes a battery storage system that can function in the event of a power outage.

How does the SGIP program work?

SGIP gives people an upfront discount based on the storage capacity of the battery they install. The sooner you register for SGIP, the bigger rebates you will receive. This is because SGIP has a tiered tariff structure, which means the amount of SGIP incentives decreases as more batteries are installed.
