The global transition to clean energy has positioned hydrogen as a frontrunner in the race to decarbonize transportation. As sectors like heavy industry, aviation, and maritime struggle to reduce their carbon footprints, hydrogen-powered vehicles have emerged as a promising alternative. With its versatility, scalability, and potential for zero-emission performance, hydrogen is revolutionizing sectors that are difficult to electrify.
Hydrogen is emerging as the star of clean energy innovation in relentless pursuit of a sustainable future. Known as "the fuel of the future," hydrogen has unmatched potential to change the face of transportation across land, air, and water. Investments in hydrogen technologies are on the rise globally, with the market projected to reach $410 billion by 2030, growing at a staggering CAGR of 25% from 2021.
Recent breakthroughs are rewriting the possibilities of hydrogen. In 2023, Airbus announced successful tests of its hydrogen-powered jet engine, bringing us closer to commercial zero-emission flights. Similarly, Hyundai launched its next-generation hydrogen-powered truck, XCIENT Fuel Cell, operating in Europe and clocking over 4 million kilometers in real-world operations. On the water, Norway debuted its fully hydrogen-powered ferry, MF Hydra, signaling a shift in maritime transport toward greener alternatives.
A leading global hub, India is positioning itself for green hydrogen. India's NGHM was initiated by the country in 2023 with an initial outlay of ₹19,744 crore or $2.4 billion. The ambitious plan will make it a net exporter of green hydrogen. Indian Oil, Reliance, and NTPC, a few domestic majors, are to lead large-scale hydrogen projects and help India bag 10% of the global market for green hydrogen by 2030.
The Case for Hydrogen in Transportation
Hydrogen’s unique properties make it a compelling clean fuel:
- High Energy Density: Hydrogen provides a higher energy output per kilogram than conventional fuels, making it ideal for heavy-duty transport like trucks and ships.
- Rapid Refueling: Unlike batteries, hydrogen tanks can be refueled within minutes, minimizing downtime for commercial vehicles.
- Versatility: Hydrogen can power fuel cells for electric propulsion or be combusted directly in modified engines.
- Decarbonization Potential: When produced from renewable sources, green hydrogen offers a pathway to zero-emission transport, addressing sectors where electrification faces limitations due to weight or range concerns.
Applications Across Land, Air, and Water
- Hydrogen-Powered Trucks:
Heavy-duty trucks account for approximately 20% of global road transport emissions despite representing only 2% of vehicles. Hydrogen-powered trucks, such as those developed by Hyundai and Nikola, offer long-range capabilities, up to 1,000 km per refueling, and high payload capacities. Companies like Toyota and Daimler are also investing heavily in hydrogen truck fleets, aiming to replace diesel in freight transport.
- Hydrogen-Powered Ships:
Maritime transport is responsible for nearly 3% of global greenhouse gas emissions. Hydrogen, particularly in its liquid or ammonia forms, is being explored as a clean maritime fuel. Projects like the world’s first hydrogen-powered ferry in Norway and Maersk’s green methanol-fueled vessels highlight progress in reducing emissions in shipping.
- Hydrogen-Powered Airplanes:
The aviation industry contributes approximately 2.5% of global CO2 emissions, and hydrogen is emerging as a viable solution for short- to medium-haul flights. Airbus’s “ZEROe” program envisions hydrogen-powered commercial aircraft entering service by 2035. Startups like ZeroAvia are testing hydrogen-electric engines for smaller aircraft, with successful test flights already conducted.
The Role of Green Hydrogen
Green hydrogen is produced through electrolysis using renewable energy, ensuring near-zero emissions. With decreasing costs of solar and wind energy, the production of green hydrogen is becoming increasingly viable.
Key Trends in Green Hydrogen Adoption:
- Declining Costs: The International Renewable Energy Agency- IRENA- predicts the cost of green hydrogen could fall to $1.50/kg by 2030, making it competitive with fossil fuels.
- Expanding Infrastructure: Global investments in hydrogen refueling stations are increasing, with countries like Japan, Germany, and South Korea leading the way.
- Government Initiatives: Policies such as subsidies for electrolyzers and mandates for hydrogen blending in industrial processes are driving growth.
India is uniquely positioned to lead in green hydrogen due to its abundant renewable energy resources, low production costs, and government support.
Policy Approaches to Hydrogen Adoption
Effective policy frameworks are critical to promoting hydrogen adoption across sectors. The following approaches are shaping the Hydrogen Horizons globally and in India:
- Financial Incentives:
Governments are offering subsidies, tax credits, and grants for hydrogen production and infrastructure development. For example, the EU’s Clean Hydrogen Alliance aims to support over 6 GW of green hydrogen capacity by 2030.
- Public-Private Partnerships:
Collaborative models are encouraging investments in hydrogen projects. In India, Reliance Industries is working with global partners to develop a hydrogen ecosystem under its $10 billion green energy plan.
- Regulatory Support:
Policies mandating hydrogen blending in refineries and fertilizer production or setting hydrogen fuel quotas in transport are accelerating demand.
- Innovation Funding:
Programs like India’s National Green Hydrogen Mission, NGHM, with an initial allocation of ₹19,744 crore, aim to support R&D, pilot projects, and production incentives for green hydrogen.
- Carbon Pricing:
Mechanisms like carbon taxes and credits can make hydrogen more competitive with fossil fuels.
