Heating for commercial and residential buildings represents 53% of Scotland's total energy demand. This makes decarbonisation heat a key challenge.

Hydrogen can be used as an alternative to natural gas for space and water heating and can potentially be delivered through the existing gas distribution network following upgrade. Switching from natural gas to hydrogen has been identified as the principal option to enable the gas networks to continue supplying energy for space and water heating in line with climate targets.

This report reviews recent literature and summarises what we know from existing and planned hydrogen-for-heat projects with relevance to the Scottish context.
