The global hydrogen combustion engine market, valued at USD 35 billion in 2030, is projected to reach around USD 89 billion by 2040, growing at a CAGR of 9.78%. Similarly, the hydrogen engine market, valued at $2.6 billion in 2022, is expected to reach $10.5 billion by 2028, growing at a CAGR of 26.8%. In India, the internal combustion engine market is projected to reach USD 8.3 billion by 2026, growing at a CAGR of 7.6%. These trends indicate a future for H2ICE technology in the pursuit of sustainable energy solutions.

This growth is not just theoretical, companies like:

Cummins is gearing up India’s hydrogen engine future! They showcased HICEVs at CII EXCON 2023, developing 6.7L and 15L versions for commercial vehicles and heavy trucks respectively. Partnering with Tata Motors, they’re building a massive factory in Jamshedpur, producing 4,000 heavy truck HICEVs and 10,000 smaller HICEVs annually.

Hyundai Doosan Infracore (HDI) is developing an HICE that meets Zero CO2 and Zero Impact Emission standards. The 11-litre class engine delivers a power output of 300 kW and a torque of 1700 NM at 2000 RPM. It’s suitable for mid-to-large-size vehicles and long-distance travel, offering a range of up to 500 km on a 10-minute charge. The engines are 25-30% more economical than battery packs or fuel cells. HDI plans to commercialize the engines by 2025, installing them on commercial vehicles, including large buses, trucks, and construction equipment.

Deep dive into our work

The hydrogen combustion engine has gained renewed interest from the heavy-duty internal combustion engine (ICE) industry as an enabler for fast decarbonization of well-to-wheel emissions. The advancements by Cummins and HDI are indicative of the significant progress being made in the field of Hydrogen Internal Combustion Engines (HICE). The impressive specifications of HDI’s 11-litre class engine, with its high power output and efficiency, underscore the potential of HICE technology. This progress is not isolated but is part of a larger global movement towards sustainable energy solutions

Research and development steps like engine optimization, green hydrogen infrastructure, and cost reduction are crucial. Opportunities include cleaner heavy-duty transport, energy security, economic growth, and technology leadership. Initiatives like FAME-II and the National Green Hydrogen Mission are paving the way. Challenges like high costs and limited infrastructure remain, but India’s commitment positions them as a potential global leader in the HICEV revolution.
