Form Energy CEO on the Potential for a 100-Hour Battery

Co-founder Mateo Jaramillo described how the startup’s iron-air battery could help address the data center boom — and the energy transition

Well before the introduction of ChatGPT and Claude, Ireland underwent a data center construction boom similar to the one the U.S. is experiencing today.

That makes it a fitting location for Form Energy’s first project outside the U.S. Mateo Jaramillo, the CEO of the long-duration energy storage startup, described Ireland as “a postcard from the future” at Heatmap House, a day of conversations and roundtables with leading policymakers, executives, and investors at San Francisco Climate Week.

In a one-on-one interview with Robinson Meyer, Jaramillo went on to explain the potential of a 100-hour battery, calling it the duration at which you can “functionally replace thermal resources on the grid or compete with them.” Such storage capacity would not only bolster data centers’ power reliability but also speed up the transition from oil and gas to renewables.

Form Energy, which Jaramillo co-founded in 2017, is best known for its iron-air battery that can continuously discharge energy for 100 hours. In February, the startup announced a partnership with Google and the utility Xcel Energy to build the highest-capacity battery in the world, capable of storing 30 gigawatt-hours of energy, as Heatmap’s Katie Brigham reported.

Despite the troublesome state of renewables deployment in the U.S., energy storage firms like Form appear to be doing well, thanks to record load growth. “When we founded the company, we didn’t anticipate the boom of data center demand that we’re currently experiencing,” said Jaramillo. “But we did bet on the overall mega-trend being pretty firmly in place, which is electricity growth.”

In addition to load growth, battery manufacturers are still benefiting from the Inflation Reduction Act’s energy storage tax credits, which survived the deep cuts Republicans made to the signature climate law last summer. Jaramillo noted that customers can still claim a tax credit for purchasing energy systems, while a manufacturing protection credit also remains in place. “We absolutely qualify for both those things,” Jaramillo said. “In fact, 100 hours as a duration is written into the legislative text for the manufacturing [tax credit].”

Though batteries can help accelerate the retirement of natural gas plants by providing firm energy to supplement renewables’ generation, politicians’ fear of load growth seems to have forged a bipartisan consensus supporting batteries. For its part, Form Energy is focused on continuing to drive down the cost of its iron-air battery.

From “where we sit today,” Form Energy is “quite confident that we will hit that roughly $20 a kilowatt-hour cost within a very short period of time,” Jaramillo said.

A Permitting Hallelujah

Current conditions: Floodwaters from the remnants of Hurricane Polo breached a 20-foot dam in southern New Mexico, forcing evacuations • The Pacific’s active hurricane season continues as Hurricane Rachel threatens dangerous rip tides off Baja California • Further north in the Pacific, Tropical Storm Choi-wan is headed toward the Northern Mariana Islands.


THE TOP FIVE

1. The permitting reform omnibus just dropped

It’s 417 pages — or, for those of you who think in such terms, roughly two-and-a-three-quarters the length of a standard environmental impact statement. And it the landed yesterday with much fanfare. The Senate’s grand compromise on permitting reform, dubbed the Bipartisan American Affordability and Jobs Act, or BAAJA, is packed with sweeping changes that promise to upend how data centers are built, whether transmission lines get constructed at all, and speed up deployments of all kinds of energy infrastructure. My colleagues — there are five bylines on this sucker, if you have any doubt about how seriously Heatmap is taking this — have a dense and comprehensive explainer here.

Exclusive: Stellantis-Backed Geothermal Startup Prepares to SPAC

Controlled Thermal Resources has completed key financial steps ahead of its planned Nasdaq debut.

California’s inland Salton Sea is a potential clean energy double dip, with vast and largely untapped geothermal hotspots for generating heat and electricity and rich deposits of lithium, manganese, and other critical minerals needed to fuel the battery revolution.

Now one of the companies looking to commercialize both resources is taking a big step toward debuting on the stock market.

The Senate’s Big Bipartisan Permitting Deal, Explained

The Bipartisan American Affordability and Jobs Act would remove longstanding roadblocks to expanding the power grid and developing new energy infrastructure. Here’s our guide.

It’s taken two presidential administrations, four years, and who-knows-how-many proposals that never saw the light of the Senate floor. But a long-awaited bipartisan deal to streamline the country’s permitting system is here.

On Tuesday, a bipartisan gang of senators — the leaders of the Environment and Public Works and Energy and Natural Resources committees — released an omnibus legislative package meant to streamline many permitting processes across the country.
