PROVIDING THE APPROPRIATE SAFETY ASSESSMENTS AND PATHWAY TO THE FIRST COMMUNITY TRIALS USING HYDROGEN AS A HEATING SOURCE

OVERVIEW:

Across industry and among the wider public, there’s an increasing awareness and understanding of hydrogen’s potential strategic role as a decarbonised energy carrier.

 

The Hy4Heat programme aims to establish if it is technically possible, safe, and convenient to replace natural gas (methane) with hydrogen in residential and commercial buildings and gas appliances.

 

Working Package 7 of the programme oversees the “Safety Assessment” and has focused on assessing the safe use of hydrogen gas in certain types of domestic properties and buildings.

 

The Health and Safety Executive (HSE) has independently reviewed the Hy4Heat Safety Assessment and has written a letter of assistance to BEIS confirming its relevance to gas network operator future duty holders for trials.

This event will highlight key findings of the Hy4Heat safety assessment and assist in navigating the extensive suite of publicly available reports. Some of the speakers contributed to that assessment. However this event is not part of the Hy4Heat programme, and is not government sponsored.

FOCUS:

  • Understanding how 100% hydrogen can be made as safe as natural gas is when used for heating and cooking in certain types of houses

 

  • Highlighting the importance of this milestone on the pathway to the first community trials using hydrogen as a heating source

 

  • Providing a verified and appropriate basis for designing and forming a risk assessment for future trials which can by drawn on by network operators

 

  • Supporting industry to begin a large village hydrogen heating trial and to set out plans for a possible pilot hydrogen town before the end of the decade

10:00 -> 10:15 -> PRESENTATION
Gas Dispersion Data Analysis

A review of experimental data focusing on how natural gas and hydrogen gas disperses and accumulates within an enclosure.

Consequence Modelling Assessment


A comparative modelling assessment of the consequences in the event of a gas leak and ignition event for natural gas and hydrogen gas.

SAM GREG, Senior Consultant - ARUP

11:00 -> 11:15 -> PRESENTATION
Safety Assessment: Conclusion’s Report
