As the current method of delivering the world’s transportation energy demand via fossil fuels becomes increasingly unsustainable, vehicle manufactures and organisations are looking to alternative energy sources for vehicle propulsion such as hydrogen fuel.

This project has been undertaken to establish the feasibility of the System Design of a Hydrogen Induction System as a Retrofit Item Compatible with Existing Internal Combustion Engines, by examining the conversion of a Holden 5.0L V8 to accommodate hydrogen combustion. The for the purpose of analysis, a Holden HX GTS sedan has been chosen as a case study vehicle, commonly optioned with the first generation Holden 5.0L V8.

Analysis of urban and extra-urban drive cycles provided theoretical power requirements for the operation of the vehicle for the duration of the cycles. Outputs from the drive cycle analysis were used in an engine simulation model that was modified to accommodate simulation of hydrogen combustion.

Input values for average power and engine speed required to maintain velocity along the drive cycles are supplied to the engine simulation model. The engine simulation model returns a hydrogen fuel consumption of 4.18 kg/100km and 5.34 kg/100km for the extra- urban and urban driving cycles respectively, a gasoline gallon equivalent of 15.4 L/100km and 20.27 L/100km. This provides a theoretical endurance of 133.62 km and 104.14 km from vehicles proposed 5.6 kg of useable hydrogen storage for the cycles respectively.

An extensive literature review is used to identify design modifications that are required to accommodate hydrogen combustion in internal combustion engines. A trade study is used to identify the measures specifically required to adapt the Holden 5.0L case study engine to dual hydrogen/petrol operation modes. The modifications and additional components required were costed where possible, resulting in an estimated minimum cost
of AUD $12,664 in parts for the conversion.
