H2G Green Limited and its subsidiary Green Energy Investment Holding Private Limited (GEIH) have entered into a licensing agreement with Singapore’s Agency for Science, Technology and Research (A*STAR) to scale up a biochar purification process for sodium-ion battery anodes. Under the agreement, GEIH will commercialise a proprietary treatment method developed by the A*STAR Institute of Materials Research and Engineering (IMRE) to purify biochar—a byproduct of GEIH’s biomass-to-hydrogen process—into hard carbon material for market use. Hard carbon is widely used as anodes in sodium-ion and lithium-ion batteries and finds applications in water and air purification systems, as well as conductive additives in coatings and paints.
In the initial exploratory phase, GEIH-produced hard carbon demonstrated higher graphite content compared with existing commercial materials, a property that improves anode performance for grid-scale energy storage, electric vehicles, and consumer electronics. Sodium-ion batteries, which rely on more abundant raw materials than lithium-ion systems, offer a potentially more sustainable alternative.
Mr. Sydney Kwan, CEO of GEIH, remarked: “We are deeply grateful to A*STAR for their ongoing collaboration and support. Our joint efforts are transforming the nation into a hub for sustainable technologies and green energy.”
GEIH’s core technology employs a high-temperature thermochemical process to convert various types of biomass (excluding high-silica feedstocks) into green hydrogen, biochar, bio-oil suitable for sustainable aviation fuel, and wood vinegar. The process emphasizes circularity and incorporates carbon sequestration, with end products serving industries ranging from data centres and semiconductor fabrication to agriculture and food manufacturing.
Following the licence execution, GEIH and A*STAR will collaborate on scaling up production of hard carbon for sodium-ion battery anodes. GEIH CEO Sydney Kwan commented that the partnership advances Singapore’s position as a hub for sustainable technology.
Mr. Pek Hak Bin, CEO of H2G, added: “Hydrogen is the energy of the future and a core part of Singapore’s low-carbon energy strategy. H2G is expanding possibilities for Singapore and beyond by pioneering a novel hydrogen production process that is cost-effective, less carbon intensive than electrolysis, and repurposes waste into sustainable materials. These power sustainable industries, as our hard carbon anode materials for sodium-ion batteries will empower a broader range of industries to reduce their environmental impact. In this way, H2G creates win-win-win sustainability solutions to multiple problems across industries.”
