This Practice Note summarises the key revenue support and other funding mechanisms under development by the UK government for low carbon hydrogen projects in the UK. It covers the Business Models for eligible hydrogen production (HPBM), transport (HTBM), storage (HSBM) and hydrogen to power (H2P) projects (H2PBM), and the processes through which funding is awarded via these models. It also explains the role of the Low Carbon Hydrogen Standard (LCHS), the Net Zero Hydrogen Fund (NZHF) and Hydrogen Allocation Rounds (HARs) under the HPBM. The Practice Note also briefly considers some of the key UK government funding schemes for new, low carbon technologies which include, but do not exclusively relate to, low carbon hydrogen such as the Net Zero Innovation Portfolio (NZIP) and the Green Industries Growth Accelerator (GIGA) fund.
