ShipTown has created the H-Battery, a single-unit system that merges electrolysis and fuel-cell functions, inspired by NASA’s alkaline fuel-cell technology. The technology can store excess renewable electricity as hydrogen and later supply electricity back to the grid or to energy-intensive sites such as data centres and Power-to-X facilities. ShipTown reports electrolysis efficiencies of roughly 90 % and fuel-cell efficiencies near 60 %, positioning the solution among the most promising for large-scale energy storage. Since inception, the company has advanced its prototypes through soft-funding programmes, accelerator participation (Beyond Beta) and grants from Innobooster, Fyrtårn Syd and Tønder Energi- og Miljøfond, as well as support from Energy Cluster Denmark. The new capital injection will let the team build next-generation prototypes, run larger-scale tests and hire specialised talent. Management aims to deliver a 2 MW full-scale pilot module by 2027 and ultimately build a global Danish manufacturing company with significant CO₂ impact.
