Pilot 7. Hydrogen heating for public buildings

Scope:

Hydrogen-natural gas blending for a cleaner hospital

The hospital will blend up to 20% hydrogen with natural gas in its existing boiler system, aiming to lower CO₂ emissions from heating (currently around 10,000 tonnes/year). A new hydrogen distribution network will be installed, with two new gas mixers in each boiler that will blend natural gas and hydrogen in the desired proportions. The pilot will also explore the use of a dedicated hydrogen burner in one boiler as a test case. Annual hydrogen consumption is estimated at up to 200 tonnes.
