HBOX SOLAR A SOLAR POWERED ELECTROLYSER - ITM Power

Case Study 03HBox Solar: A Solar-Powered ElectrolyserThe Challenge of Intermittent Renewable Energy SourcesThe increasing need for capturing intermittent renewable energy at times of high availability promptedITM Power to develop an effective solar hydrogen generation solution.• High efficiency PEM electrolyser• High overall system efficiency and very lowparasitic balance-of-plant (BoP) loads• Capable of operating off-grid and load-followingthe fluctuating nature of a PV power source• Intelligent control for maximum power pointtracking (MPPT) the available PV input• A novel PEM electrolyser stack design integratinghydrogen generation and balanced pressurisation,with passive water-gas separation and passiveelectrolyser cooling• A thermal management system for maximising thegas production rate after each period of darknessor bad weather• No moving parts for high reliability andunsupervised operation in remote locationsfor extended periodsHBox Solar – Exploded View
