• Task 1: Market overview, focusing on equipment types installed in the UK,

• Consultation with manufacturers and suppliers to understand range of equipment and control system options.

• Collation of information from OEMs highlighting current understanding of hydrogen content limitations.

• Task 2: Study on gas engine fuelled by hydrogen/natural gas

• Install and commission the gas engine and associated test rig facilities.

• Undertake benchmark, reference tests on the operation of a gas engine. The tests will establish the baseline response when operating on natural gas.

• Perform tests on the gas engine with increasing hydrogen content of fuel gas. Measurements will be taken to develop the understanding of the impact on performance and emissions as the quantity of hydrogen is increased.

• Detailed analysis of the test results

• Task 3: Reporting of the impact of hydrogen on the results and output from the market overview and the technical study, to include:

• performance of the engine with blends of natural gas and hydrogen in terms of efficiency/emissions/operability

• an indication of the potential upper limit to hydrogen content of natural gas for use in gas engines.

• Output from the discussions/meetings with OEMs – barriers, control system developments, component issues

Options for future developments that may be required to overcome any barriers

Benefits

Studying the real impact of hydrogen/natural gas blends on a gas-engine CHP system as an example of an I&C applications

Developing knowledge on the operation of a gas-engine CHP system to inform key stakeholders and assist in expanding the evidence base on which to evaluate options for future gas quality limits associated with hydrogen content of natural gas

Collation of responses from OEMs and trade associations regarding wider views on gas-engine CHP systems operating on hydrogen/natural gas blends, including potential equipment and control system developments
