EnerVenue Holding, Ltd. (“EnerVenue”) announced today the closing of its U.S. $300 million extension of its Series B preferred stock financing round. The extension round was led by Full Vision Capital.
Incubated by Full Vision Capital, EnerVenue also announced the appointment of Henning Rath as Chief Executive Officer (CEO). With the investment and strategic support of the Hong Kong Investment Corporation Limited (“HKIC”), the company plans to establish a regional headquarters in Hong Kong to coordinate sales across the region, alongside an innovation center that will attract scientists from Hong Kong and abroad to advance materials research. The company also intends to partner with local universities to nurture industry talent.
In recent years, Professor Yi Cui of Stanford University, together with the EnerVenue team, has overcome longstanding industrialization barriers of Aqueous Metal Cell (“AMC”) batteries, which have a proven heritage in aerospace applications, converting this technological breakthrough into a scalable, commercially viable solution. Ranked 10th on TIME’s America’s Top GreenTech Companies of 2025, EnerVenue is now positioned as a pioneering leader in the global green energy revolution. The new round of financing will further accelerate the large-scale industrial application of the energy storage technology.
“This $300 million extension of Series B preferred stock funding is a testament to the strength of EnerVenue’s technology and the entire team’s execution,” said newly appointed CEO Henning Rath. “The capital is crucial for further R&D of our core technologies, ramp-up of large‑scale manufacturing, reinforcement of supply‑chain robustness, and expansion of global commercial reach. It also provides runway for achieving our short- and medium-term production capacity targets.”
Rath, an internationally recognized technology executive with a distinguished record of building billion-dollar companies and deep expertise in the global energy sector, guided the company to this successful funding milestone.
“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.”
Ms Clara Chan, CEO of the HKIC, remarked, “By investing in EnerVenue, the HKIC is empowering the Company with our capital, platform and talent networks to accelerate the development of the Company’s groundbreaking technology, and establishing a model on the transformation of frontier green technology into industrial applications and commercial return. Hong Kong will help companies like EnerVenue to optimise their global action plan and serve as a gateway to international market, leveraging our strengths as international financial center, “super-connector”, and “super value-adder”. As part of this journey, applications of the relevant green technology will also contribute to the rest of the world, bringing benefits to all parties involved.”
Mr. Alan Chan, Co‑founder of EnerVenue and Managing Partner of lead investor Full Vision Capital, said, “We are deeply honoured to receive the strong support and recognition of the HKIC. This marks an important step in accelerating our mass‑production capabilities. With the launch of our Hong Kong regional office and innovation center, we look forward to partnering with HKIC to leverage Hong Kong’s pivotal role as a global green‑technology and green‑finance hub, and to advance the city’s standing as an international technology and innovation center.
