EnerVenue Holdings, a company that develops metal-hydrogen batteries, announced the closing of a $300 million extension of its Series B preferred stock financing round.
The extension round, led by Full Vision Capital, included a new investor. Along with this funding, the company has also appointed Henning Rath as Chief Executive Officer. Earlier, Rath was Managing Director and Chief Supply Chain Officer at Enpal, a Germany-based residential renewable energy provider.
The newly raised funding will help accelerate its shift from an advanced technology developer to a high-volume manufacturer, enabling broader deployment and meeting the growing demands of AI-driven energy systems.
EnerVenue’s technology uses an aqueous metal cell with a nickel hydroxide cathode and nickel alloy anode in an alkaline electrolyte. During charging, hydrogen gas is generated and stored within a sealed, large-format cell, and consumed again during discharge.
The capital will support the scale-up of EnerVenue’s high-volume manufacturing operations in Changzhou, China, and also accelerate supply chain development and commercial expansion.
“Henning’s leadership has been pivotal in positioning EnerVenue for this growth phase,” said Dr. Yi Cui, chairman of EnerVenue. “His strategic vision and operational credibility were instrumental in building investor confidence and closing this significant round. His deep expertise in industrial scaling and global market execution is exactly what EnerVenue needs to achieve its ambitious manufacturing and deployment goals.”
To expand its global footprint, EnerVenue is supported by strategic investors, including Aramco Ventures. Over the coming months, the company plans to expand its commercial operations across Asia, the Middle East, and Europe.
In 2021, the company raised $100 million in Series A funding led by Schlumberger New Energy, followed by $308 million in Series B funding in 2024.
According to Mercom’s Annual and Q4 2025 Funding and M&A for Energy Storage report, Energy Storage Downstream companies received the most VC funding in 2025. Other top-funded categories included Materials & Components providers, Energy Storage Systems providers, Battery Recycling, and Li-based Battery companies.
