The proposed project has three phases:
• Phase 1: Project definition: Complete a literature review, consultation with truck OEMs, and collation of existing data/research to develop a detailed understanding of current position with respect to use of blended methane/hydrogen mixes in heavy transport/HGV applications. This will highlight issues to be investigated in Phases 2 and 3 with regard to gas engine operation and control systems.
• Phase 2: Project Planning and Design; Detailed planning of engine test and combustion modelling tasks and confirmation of the feasibility of conversion of the University of Brighton Euro VI single cylinder Diesel engine to Spark ignited methane fueling.
• Phase 3: Single cylinder engine test and modelling work: Engine test and modelling work will be performed to investigate the effect of varying hydrogen concentrations on combustion efficiency and emissions at varying engine speed, load and air/fuel ratio and to simulate performance over a drive cycle to understand real world effects.
The overarching objective of the project is to provide evidence of the effect/impact of introducing hydrogen into the gas supply on natural gas fueled transport applications (especially methane engines used in HGVs).

The project will have a number of task-oriented sub-objectives;

• Produce data sets of the impact of hydrogen on gas engine operational performance when used in transport/heavy freight vehicle applications
• Provide guidance on the potential hydrogen limit that should be considered regarding use of natural gas/hydrogen blends in gas engine transport/heavy freight vehicle applications
• Identify any barriers to use of natural gas and hydrogen blends in above transport applications
• Develop understanding of future technology developments that may be required to enable use of high hydrogen blends (this could extend to engines, control systems, and on-board fueling equipment etc.)

Output will also inform HyNet, HyNet Motion, HyPurity and HyDeploy NIC projects in relation to potential hydrogen content limits. Consider presenting results at the IGEM Gas Quality Working Group (IGEM GQWG).
