Study: Hydrogen Combustion Engines Remain in the Niche
According to a recent study by Interact Analysis, the global hydrogen combustion engine industry shows slight signs of growth but must still overcome a number of obstacles to achieve widespread acceptance. The report "Hydrogen ICE – 2024" identifies the main barriers to market breakthrough, including high fuel costs, high wear on expensive injectors, and a lack of existing refueling infrastructure.
The Interact Analysis study predicts that by 2030 a maximum of 13,150 hydrogen combustion engines will be registered annually worldwide, which represents only a very small proportion of the hundreds of millions of new vehicles coming to the market. By 2040, the increase in registration numbers for hydrogen combustion engines is expected to reach only 100,000 units per year.
Limiting Fuel Injectors
Jamie Fox, Principal Analyst at Interact Analysis: "Due to the lower efficiency of H2 combustion engines, especially in trucks and buses, the cost per kilometer is even higher than for fuel cell drives."
Apart from high fuel costs and the lack of refueling infrastructure, there are technical challenges that stand in the way of the widespread introduction of H2 combustion engines. The most important of these are pre-ignition – which occurs mainly in combustion engines – and the short lifespan of the fuel injectors due to lack of lubrication, which currently stands at just over 1,000 hours. In the long term, the goal is to reduce the cost of a fuel injector, which is currently about $1,000, as much as possible to $100. However, other problems such as leakage, embrittlement, and the need to redesign the engine are also cited as obstacles.
