Hyundai Doosan Infracore Co. will develop a hydrogen combustion engine that will be mounted in commercial vehicles, buses, and construction machinery by 2024.
The engine will be mass-produced by 2025 after going through a verification process.
The South Korean construction equipment maker was selected as the lead agency for the development of hydrogen engine and storage and supply systems for construction machinery and commercial vehicles.
Through this national project conducted by the Korea Evaluation Institute of Industrial Technology, the company will create hydrogen engines and hydrogen tank systems with a 300 kW output and an 11 liter displacement that could achieve zero carbon emissions .
Hydrogen engines are cost-effective as they can run on lower purity hydrogen, unlike fuel cells, which can only work on 99.99 percent pure hydrogen.
