The Energy Systems Catapult, working with Ricardo under the Hydrogen Innovation Initiative, conducted a detailed study on deploying large-scale wind facilities coupled with water electrolysers to produce hydrogen across the United Kingdom. The study evaluates the status and potential impact of various factors such as technology supply chains, geographical constraints, storage needs, and costs on wind-electrolyser systems. Key findings include the importance of expanding onshore and offshore wind, the need for rapid grid reinforcement, and the significance of supporting projects like HAR1 & HAR2 to maintain industry confidence. The study identifies regions like the Scottish Highlands, central Wales, and parts of England as having potential for hydrogen production, emphasizing the importance of transportation infrastructure planning. The insights from the study are deemed valuable for policy development and energy systems planning in the UK, setting the groundwork for future strategic decisions in the renewable energy sector.
