Innovate UK has provided £630,000 to support a project in Portland, Dorset, aimed at producing green hydrogen directly from seawater for a harbour patrol vessel. The project, called HydroPort trials, will be conducted by start-up Latent Drive, which will assess the market potential of its SeaStack electrolyser technology. The technology eliminates the need for desalination and rare metals typically required in conventional hydrogen production methods. Despite challenges like chlorine gas production, the SeaStack technology promises high-purity hydrogen production with fast response to electrical power fluctuations. This project involves collaboration with Dorset Council, Logan Energy, Saline Business Services, and the University of Exeter's Centre for Future Clean Mobility. Latent Drive plans to install the technology on harbour walls, offshore wind turbines, and floating platforms. The company aims to revolutionize clean hydrogen production, focusing on location and economics. The successful implementation of this project could lead to significant advancements in green hydrogen production, contributing to the energy transition and clean mobility solutions.
