Hydrogen-powered


A thriving low carbon hydrogen sector is a key plank of the government’s ambitions to build a cleaner, greener energy system and enable the UK’s transition to net zero. It is seen as having the potential to overcome some of the most difficult decarbonization challenges across a range of sectors; domestic and commercial heating, industrial processes, freight transport, maritime and aviation. In 2021 the government published its


first ever UK Hydrogen Strategy in which it sets out a bold ambition to deploy hydrogen at scale. This will not only help meet decarbonization targets but also boost the economy, create jobs, as well as generate export opportunities by positioning the UK as a global leader in hydrogen technology development and low carbon hydrogen production. More recently, in April the UK government published its British Energy Security Strategy’ which includes a significant increase in the UK’s hydrogen production ambition with up to 10GW of low carbon hydrogen capacity to be made available by 2030.


BSI has a track record of supporting


hydrogen innovation already, having an established technical committees structure and more recently, working as part of the government Hy4Heat programme, and supporting other initiatives such as HyDeploy and Gas Goes Green (GGG). BSI was commissioned by the Department


for Business Energy & Industrial Strategy (BEIS) to develop a fast track PAS. Published in 2020, PAS 4444 offers guidance on the development and construction of

hydrogen-fired gas appliances in support of Hy4Heat. PAS 4444 has been key to industry demonstrating that hydrogen appliances can comply with the requirements of the Gas Appliance Regulations and receive UKCA or CE marking. This created a pathway for appliances to be certified as they move out of the lab and into trials. With Hy4Heat and HyDeploy now having


largely proved the feasibility and safety of using hydrogen for heating, and with the publication of a long-term strategic approach to hydrogen production and use (reflected in the UK Hydrogen Strategy), hydrogen development has moved into a new phase. BSI is currently contributing to BEIS’


Hydrogen Skills and Standards for Heat Programme to enable the UK’s future hydrogen village trial and a potential town pilot. This work looks to establish an


agreed set of principles, requirements and guidance on functionality, safety, operating and servicing requirements for ancillary equipment, pipework, materials, meters, and appliances through the development of an initial suite of three PAS standards (see pop-up, above). BSI’s Hydrogen for Heating Standards


programme has thus far seen BSI collaborating with key standards partners and a wide range of stakeholders to scope the PASs with a view to having them developed and ready for publication in 2023. In the programme BSI is working closely with the Institution of Gas Engineers and Managers (IGEM) and the Energy Utilities Scheme (EUS) to deliver standards and training in support of the planned village and town hydrogen trials, and beyond. In other areas of hydrogen application, BSI is also supporting two new

programmes of work being run by the Connected Places Catapult to establish the feasibility of using hydrogen in decarbonizing road freight transport – the mode of transport with the largest carbon emissions – and in aviation. The ZERFT (Zero Emissions Road

Freight Trials) programme, backed by the UK government, is assessing the safety and regulatory compliance of hydrogen fuel cells in heavy goods vehicles (HGVs). Meanwhile, the ZEFI (Zero Emissions Flight Infrastructure) programme is supporting the aviation industry in preparing airports and air-fields to service hydrogen-powered and battery electric aircraft. In both programmes, BSI is aiding the effort by exploring the need for new standards in the use of hydrogen to decarbonize road freight and flight and also the role that new and existing standards might play.
