Research

This projects builds on the research done in RP1.4-01 and RP1.4-01B and aims to defining a practical upper limit for hydrogen addition to natural gas for operation of domestic gas appliances. An upper hydrogen percentage limit in blends with natural gas based on minimal changes to appliances will be indicated.

As part of this project a range of new and legacy appliances will be tested, including cookers and flueless heater systems. The project will also test 100% hydrogen burners in terms of their ability to operate safely on hydrogen / natural gas mixtures.

The key outcomes of this project will include:

• A recommendation on a maximum hydrogen percentage that can be tolerated in blends with no changes to equipment – considering most types of Type A appliance.  This may include a minor reduction in heat output (assuming no increase in regulator pressure). 
• Information on whether minor changes to some equipment will increase the allowable maximum % hydrogen in a blend. 
• Documentation on a small trial of legacy appliances with hydrogen blends 
• Further information on cooker light-under, ODS and 100% hydrogen appliances
