About Equisera
At Equisera, we are driving the transition to carbon-negative energy with our patented Rising Pressure Reformer (RiPR) technology. Our breakthrough process converts wet biogenic feedstocks – including agricultural and food waste, and even plastics – into high-yield hydrogen and biomethane with minimal pre-processing. Both outputs capture carbon dioxide and generate biochar, creating a truly carbon-negative fuel solution.
Designed to decarbonise hard-to-abate sectors, our hydrogen and biomethane directly reduce greenhouse gas emissions. The flexible RiPR process adapts to evolving policy landscapes, including hydrogen blending mandates, ensuring resilience and scalability.
Backed by significant investment and strategic partnerships, we are entering a critical scale-up phase. Equisera has recently been awarded two successful grants, driving the next stage of our technology development journey. Join our small, passionate, high-impact team and help shape a cleaner, greener energy future.
