Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, pursuant to the Answer of 13 February 2023 to Question 139259 on Natural Gas: Hydrogen, when he plans to make a decision on allowing hydrogen blending.

The Government aims to reach a policy decision in 2023 on whether to allow blending of up to 20% hydrogen by volume into the gas distribution networks. The Government is assessing whether there is value in having blending available to support the development of the hydrogen economy and achieve wider net zero objectives. The Government is reviewing evidence to determine if blending represents strategic and economic value and meets the required safety standards. Blending of 20% hydrogen by volume is regarded by industry as the limit which, if exceeded, may start to impact domestic and non-domestic appliances negatively.
