This document discusses the potential for hydrogen and renewable energy in Lithuania and the UK. It provides several case studies as examples: - The PURE Energy Centre on Unst Island in Shetland produces hydrogen from wind turbines which can be stored and used in fuel cells for power and heat. This has helped energy independence and local jobs. - The Environmental Energy Technology Center plans to use an iconic renewable hydrogen system with electrolysis, storage, fuel cells and connection to the grid to support innovation. - Woking Park uses a fuel cell to provide heat and power to nearby buildings from a combined heat and power system, improving efficiency over separate electricity and heat production.
