Overview

Decahydron Limited is a company based in Ireland, operating under CRO number 769320. The company is engaged in clean energy and carbon removal technologies, focusing on the extraction of natural hydrogen from deep geological formations. Its name suggests a focus on sustainable energy and environmental solutions. The business leverages ultramafic rock formations to generate hydrogen through serpentinization, a natural geological process, and uses the same rock formations to mineralize carbon dioxide, converting industrial emissions into stable carbonate minerals. This dual approach aims to deliver a carbon-negative solution by producing clean hydrogen and permanently storing carbon in stone. The company emphasizes scalable, nature-led technology with a target cost of under $1/kg for hydrogen production. The website highlights its mission to address two global challenges: clean energy and carbon emissions. Beyond registry-level identification, no further business details are publicly captured.
