GreenHy2 (ASX:H2G) has partnered with European tech firm H2Core to integrate advanced supercapacitor battery and low-pressure hydrogen (LPH) storage solutions. The agreement is expected to improve cost efficiency and sustainability across GreenHy2’s energy storage systems.

The graphene-based supercapacitor batteries offer a lifespan of 25 to 40 years—far exceeding the 6 to 10 years typical of lithium-ion (Li-ion) batteries. They also feature a 100% depth of discharge, boosting usable capacity by 20-25%. Unlike Li-ion, supercapacitors pose no thermal runaway risk, charge in minutes rather than hours, and are fully recyclable, using synthetic graphene instead of mined materials.
These advancements make them a viable Li-ion replacement in many applications.
GreenHy2 is also advancing LPH storage, a safer, cost-effective alternative to conventional hydrogen storage. LPH eliminates thermal runaway risks and reduces maintenance requirements. The technology is already being deployed in a deal with Telstra, where it reportedly is expected to cut hydrogen storage costs by over 50%.
These developments strengthen GreenHy2’s position in the renewable energy sector. The company recently secured a $1.5 million contract to supply its Hy2MEDI generation and storage system to Telstra, backed by a federal government grant. This project highlights GreenHy2’s ability to execute large-scale energy solutions.
With global decarbonization efforts driving demand for energy storage, GreenHy2’s innovations position it for growth. The company had just over $1M dollars in cash at bank as reported in the December quarterly and $63K positive cash flow.
At the time of publishing, H2G is up over 250% in the day's trade, giving Stock Surge some hope that there remains interest in microcap stocks at the cutting edge of technology.
