Work package 7

Safety assessment

This is a key work package of the Hy4Heat programme. It will focus on assessing the safe use of hydrogen gas in domestic properties and buildings. This will include gas leakage accumulation and ventilation of gas releases in different enclosed spaces within a typical domestic property.

Experimental testing will be undertaken to support the safety assessment. Additionally information from GDNOs is being collated to support this work. This information will then feed into the quantitative risk assessment (QRA) and consequence model to support the safety assessment.

5 June 2019, BEIS appoints WP7 contractors

BEIS has appointed DNV GL and Steer Energy to conduct a range of comparative experimental tests, using both natural gas and hydrogen, that simulate scenarios found in domestic environments to quantify the relative risk of using hydrogen versus natural gas - as part of demonstrating and de-risking the use of hydrogen for heating in UK homes and businesses.

  • Steer Energy will undertake WP7 Lot 1:

    • Lot 1: Research and evidence gathering to compare the fitness for purpose of fittings and general pipework within a typical domestic property for both hydrogen and natural gas

  • DNV GL will undertake WP7 Lots 2, 3, 4:

    • Lot 2: Research and evidence gathering to compare the movement and accumulation within different confined spaces within a typical domestic property for both hydrogen and natural gas

    • Lot 3: Research and evidence gathering to compare the movement and accumulation of leaked gas within a typical domestic two storey property for both hydrogen and natural gas

    • Lot 4: Research and evidence gathering to compare the ignition risk from different gas concentrations for both hydrogen and natural gas
