Boston-based Electrified Thermal Solutions, a leader in electrified heating and thermal energy storage, has recently announced the appointment of Supratim Das as Vice President of Finance. Das joins the company from Electric Hydrogen (EH2), where he most recently served as Director of Commercial Finance and played a key role in scaling the company from an early-stage startup into a billion-dollar green hydrogen leader with a gigafactory in Massachusetts. His appointment follows the successful commissioning of Electrified Thermal’s first commercial-scale Joule Hive Thermal Battery in Texas.
A two-time Forbes honoree with a PhD and MBA from MIT, Das brings nine years of climate technology experience across scientific, investment, and operational roles. At Electric Hydrogen, he supported the company’s rapid growth through more than $700 million in debt, equity, and grant financings, and helped mitigate first-of-a-kind (FOAK) project finance risk for lenders at the $100 million-plus scale by leveraging credit enhancement and off-balance-sheet liquidity structures. As Vice President of Finance, Das will lead all corporate and project finance activities, as well as capital markets and formation strategy, as Electrified Thermal transitions from technology demonstration to scaled commercial deployment. The company is targeting delivery of 2 gigawatts of thermal power capacity globally by 2030 at a cost lower than natural gas.
Electrified Thermal’s Joule Hive Thermal Battery uses electrically conductive firebricks to store low-cost electricity as heat at temperatures up to 1,800°C (3,275°F) for hours or days, levels sufficient to replace fossil fuels in the most demanding industrial applications, including steel, cement, chemicals, and glass manufacturing. The company is backed by leading industrial investors, including ArcelorMittal’s XCarb Innovation Fund, with plans for technology validation at ArcelorMittal’s GasLab facility in Spain. Additional investors include global cement leader Holcim and Vale, one of the world’s largest iron ore producers.
“Strategic backing from the XCarb Innovation Fund and other major industry backers confirms that the Joule Hive is the definitive thermal storage solution for heavy industry. Our engineering delivers a ‘no-brainer’ advantage: the highest temperatures and direct grid integration that transforms a customer facility into a flexible, dispatchable load that provides both zero-carbon heat at cost lower than natural gas and essential grid stability,” said Das. “We aren’t competing with other thermal batteries; we are competing with natural gas, and we are winning on price, durability, and high-temperature performance. Now fully operational, we are blitzscaling to provide our partners with a carbon-free edge that makes fossil fuel-reliant operations uneconomical.”
“Supra brings deep cross-functional experience scaling energy technologies into industrial markets,” said Daniel Stack, Co-founder and CEO of Electrified Thermal Solutions. “Our technology is proven, our first commercial-scale system is live, and we are executing commercial deployments with industrial partners. Supra’s leadership strengthens our financial strategy as we scale manufacturing and build larger projects with industry partners globally.”
