SolidHydrogen and international consortium secure $AUD 2.5M to demonstrate low-cost Hydrogen production and new cooling applications.

 SYDNEY, AUSTRALIA, 21 October 2025 – A pioneering international consortium of energy innovators announced today it has secured a major grant to commercialise a new generation of low-cost green hydrogen technology. The project unites Singapore's SunGreen, Australia's SolidHydrogen, and key regional partners to tackle critical cost and supply chain barriers, positioning green hydrogen to compete directly with fossil fuels at cost parity. 

The grant will fund a multi-faceted initiative to develop and validate a highly efficient and cost-effective advanced alkaline (AEM) electrolyser system developed by SunGreen, with a single-step purification and compression process developed by SolidHydrogen. By leveraging local manufacturing pathways, the consortium will significantly reduce supply chain vulnerabilities currently hindering the sector's growth. 

The project’s innovation will be demonstrated through two key pilots: 

1. A 2kW prototype in French Polynesia designed to validate a dual-revenue model, co-producing green hydrogen and valuable cooling – a game-changer for tropical economies and off-grid applications. 

2. A 20kW pilot in Indonesia to scale a ground-breaking pressurised version of SunGreen's electrolyser. This system integrates hydrogen purification and compression (from 1-2 bar to 30 bar) into a single, elegant process, drastically cutting the capital expenditure and footprint of the overall system. 

"This grant is a powerful catalyst. We are not just optimising a single component; we are re-engineering the entire green hydrogen value chain - from production and purification to compression and storage," said Philippe Odouard, CEO at SolidHydrogen. "Our goal is to deliver a technology pathway that makes green hydrogen economically viable at scale, unlocking a sustainable energy future for the Indo-Pacific, and beyond." 

Professor Francois Aguey-Zinsou, CTO of SolidHydrogen, added: "Our focus is on elegant system integration that drives down cost. By developing a technology that simultaneously purifies and compresses the hydrogen from SunGreen’s low-pressure electrolyser, we eliminate entire stages of expensive, complex equipment. This is a fundamental shift in system architecture that dramatically lowers both CAPEX and operational complexity, making the final cost of hydrogen competitive with incumbent fuels." 

“The global energy transition demands more than incremental efficiency gains - it calls for a complete rethinking of how green hydrogen is produced, purified, stored, and delivered. At SunGreen, we’re building this foundation from the atomic level up, transforming the economics of electrolysis through advanced nanomaterials. This collaboration grant allows us to take our breakthrough technology a step further - creating a seamless, high-efficiency hydrogen ecosystem that can scale rapidly, cut costs across the entire value chain, and make truly clean hydrogen competitive with fossil fuels. We’re proud to be building this solution here in the Indo-Pacific, powered by local innovation and supply chains,” said Tulika Raj, CEO and Co-Founder of SunGreen. 

The project extends beyond technology validation. In collaboration with partners in Vietnam, the consortium will conduct in-depth techno-economic analyses, life cycle assessments, and social acceptance studies. This will create a clear roadmap for market adoption, demand growth, and the development of a robust, self-sufficient regional energy ecosystem.
