Publicly Available Specification (PAS) for Large Hydrogen Ready Boilers

Descriptions

Development of Hydrogen-ready Industrial Boiler Publicly Available Specification (PAS) Decarbonising industrial processes is an important part of achieving our net zero ambitions, and a likely early off-taker of low carbon hydrogen. We will take steps to ensure this can happen by phasing out unabated fossil fuel burning in industry and supporting possible replacements. Therefore, the Department is sponsoring the British Standards Institution (BSI) to develop a Publicly Available Specification (PAS) for large boiler equipment that is hydrogen- ready. This standardisation document will be aligned to PAS 4444, developed for hydrogen-fired and hydrogen-ready gas appliances. We anticipate this PAS will develop a standardised definition for what constitutes a large 'hydrogen-ready' boiler that will give confidence to End-Users that this equipment can enable faster and cheaper fuel switching to hydrogen than would otherwise be the case.
