| Objectives | The work will focus on two areas a technical analysis of the effects of hydrogen concentration on gas appliances. The review will cover the effect of hydrogen content on UK gas appliances. This will include analysis of the impact of gas blends on a range of areas, including: Effect on Wobbe index and energy input to the appliance. Effect on Oxygen Depletion Sensors (ODS). Effect on flame ionisation probes for flame failure detection (FFD) and those with automatic gas/air ratio control. Risk of light back to the injector. Risk of flashback for appliances with pre-mixed burners. Effect on annual servicing and complexity of situation for GasSafe fitters. Additional risks arising from this. Effect on materials of construction. Effect on commercial catering. Effect on Industrial burners especially radiative vs convective heat exchange. Additional issues if H2 composition is fixed or varies according to summer/winter storage and management of these with UK use of morning and evening heating patterns. Known issues with very variable gas quality combined with intelligent home network systems and internet connected appliances. Effect of increasing hydrogen content on risk of fire and explosion. The project objective is to review the effect of hydrogen content on UK gas appliances. This will include analysis of the impact of gas blends on a range of areas, identified in the scope. | |
| Abstract | With the challenge of decarbonising heat, opportunities such as hydrogen blending are key to enabling reduction in our carbon emissions in the short term whilst minimising the customer impact. These low impact reductions are key to moving the UK towards its net zero target. The technical challenges of blending hydrogen into natural gas are been explored in the Network Innovation Competition project HyDeploy 1 and 2. With the current projects providing the evidence to demonstrate the safety of blends within the network. It opens up the wider question when considered alongside the work on 100% hydrogen for heat. Can appliances move between blends and 100% hydrogen, if not why not? The development of hydrogen ready boilers is one angle, the deployment of these is not likely to reach large scale until the 2030s. | |
