Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what comparative assessment his Department has made of the costs of (a) Liquid Organic Hydrogen Carriers and (b) geological storage for hydrogen in the UK.

Government continues to develop its evidence base on the costs of hydrogen storage and consider the potential role of using hydrogen storage across the hydrogen value chain. The previous Government’s Hydrogen Transport and Storage Cost Report (2023) includes a comparative assessment of the expected levelised cost of above ground and geological storage. The International Energy Agency’s Global Hydrogen Review (2023) includes an assessment of the potential levelised cost of Liquid Organic Hydrogen Carriers used for international trade.
