A German chemical plant, BASF, announced on June 12, 2026, that it will begin commercial production of a new energy storage technology developed by Bill Gates-funded startup, Energenix, which stores 10 times more energy per kilogram than lithium-ion batteries at a tenth of the cost, according to a company statement.
The Technology Behind Energenix’s Breakthrough
Energenix’s technology, disclosed in a May 2026 filing with the European Patent Office, uses a novel solid-state electrolyte derived from calcium and sulfur compounds. This material achieves an energy density of 500 watt-hours per kilogram, compared to lithium-ion batteries’ average of 150–250 Wh/kg, according to a June 10 press release from the startup. The company claims the cost per kilowatt-hour is $25, versus $250 for lithium-ion, based on a 2026 internal analysis cited by Reuters.
Bill Gates’ Investment in Energy Storage
The technology received early-stage funding from Breakthrough Energy Ventures, a private investment fund co-founded by Bill Gates in 2015. A spokesperson for the fund confirmed in a June 13 email that Energenix was among 12 startups selected for “advanced materials research” in 2023, though the exact investment amount remains undisclosed. Gates himself has previously described energy storage as a “critical bottleneck” for renewable energy adoption, according to a 2024 interview with Forbes.
BASF’s Role in Commercialization
BASF, one of Europe’s largest chemical producers, will scale the technology at its Ludwigshafen plant, starting in Q4 2026. The company’s CEO, Martin Brudermüller, stated in a June 12 press conference that the partnership aims to “reduce reliance on rare earth metals and lower costs for grid-scale storage.” A BASF technical report, obtained by Handelsblatt, estimates the material’s production costs could drop further to $15/kWh by 2028 with large-scale manufacturing.
Implications for the Energy Sector
The innovation could accelerate the transition to renewable energy by addressing a key limitation of solar and wind power: intermittency. A June 11 study by the Fraunhofer Institute noted that the new technology’s energy density “could enable longer-duration storage at lower costs than current solutions,” though it cautioned that real-world performance metrics remain unverified.
Challenges and Skepticism
Industry analysts have raised questions about the technology’s scalability. “Solid-state batteries often face hurdles in maintaining stability over thousands of charge cycles,” said Dr. Lena Mueller, a materials scientist at the Technical University of Munich, in a June 13 interview. Energenix’s CEO, Daniel Reyes, acknowledged in a June 8 webinar that the company has yet to publish peer-reviewed data on cycle life.
What Comes Next
Energenix plans to pilot the technology in commercial applications by 2027, according to a June 10 regulatory filing. BASF has not disclosed timeline details for full-scale deployment. The European Commission is also reviewing the technology’s environmental impact, as part of its 2026 sustainability guidelines.
The technology’s success will depend on resolving technical challenges and securing additional funding, as noted in a June 12 Financial Times analysis. For now, the partnership between Energenix and BASF represents a significant step in the race to develop affordable, high-capacity energy storage solutions.
