- Breakthrough in low-cost graphene supercapacitor manufacturing
- New tech offers longer life and enhanced safety over lithium-ion
GreenHy2 (ASX:H2G), a developer focused on solid-state hydrogen storage, has announced a strategic contract with European technology provider H2Core. The deal is aimed at accelerating the adoption of next-generation energy storage solutions, including supercapacitor batteries and advanced hydrogen storage systems.
This partnership is part of a broader initiative involving several ongoing negotiations to integrate cutting-edge energy technologies. At the core of this agreement are developments in graphene-based supercapacitor batteries and hydrogen storage technologies, which offer substantial improvements in both cost-effectiveness and commercial scalability.
A key advancement lies in the use of graphene supercapacitors. GreenHy2 has developed revolutionary low-cost manufacturing techniques that make these energy storage systems a commercially viable option. According to the company, the resulting products merge the benefits of lithium-ion batteries and hydrogen storage, while surpassing hybrid battery solutions in performance.
Dr. Paul Dalgleish, managing director at GreenHy2, highlighted the evolving role of energy storage solutions. He explained that while supercapacitors are increasingly replacing lithium-ion in many applications, hydrogen continues to play a vital role in long-term energy storage due to its low self-discharge rate. The previously high cost of large-scale supercapacitor systems had been a limiting factor, but advancements in graphene manufacturing have changed the game.
From a longevity standpoint, the new storage systems offer a remarkable lifecycle of up to 500,000 cycles at the cell level. This equates to around 25 to 40 years of operational life based on daily usage — significantly longer than the typical 6 to 10 years associated with lithium-ion batteries. Hydrogen-based storage solutions, meanwhile, provide up to 30 years of use.
Safety is another standout feature of the new supercapacitor batteries. Unlike lithium-ion systems, which carry risks of thermal runaway and intense fires that are difficult to control, the new supercapacitors exhibit very low fire risk. Their simplified operation and improved safety profile make them suitable for a wide range of energy storage applications.
With this agreement, GreenHy2 positions itself as a frontrunner in the global shift toward sustainable and scalable energy technologies, paving the way for safer and longer-lasting energy storage solutions.
