Green Hydrogen: Decarbonizing Hard-to-Abate Industries Guide

Green hydrogen is emerging as a critical solution for decarbonizing sectors that are difficult to electrify. With significant investments and technological advances in 2025, understanding its applications and potential is essential for industrial decarbonization strategies.

What is Green Hydrogen?

Green hydrogen is produced through electrolysis using renewable electricity to split water into hydrogen and oxygen. Unlike "grey" hydrogen (from fossil fuels) or "blue" hydrogen (with carbon capture), green hydrogen produces zero carbon emissions.

Grey Hydrogen

From fossil fuels, high emissions

$1.5-6.4/kg

Blue Hydrogen

Fossil fuels + carbon capture

$2-4/kg

Green Hydrogen

Renewable electrolysis, zero emissions

$3.8-11.9/kg

Key Industrial Applications

Steel Manufacturing

Replace coal in blast furnaces with hydrogen, eliminating major source of industrial CO2 emissions.

Impact: Steel production accounts for 7-9% of global CO2 emissions

Ammonia Production

Produce carbon-free ammonia for fertilizers, currently responsible for 1.8% of global emissions.

Impact: Essential for food production, massive decarbonization potential

Refining

Replace grey hydrogen in desulfurization and hydrocracking processes, reducing Scope 1 and 2 emissions. Learn more about measuring and reducing operational emissions.

Impact: Refineries already use hydrogen, switch to green reduces massive emissions

Heavy Transport

Fuel cell vehicles for long-haul trucking, shipping, and aviation where batteries are impractical.

Impact: Decarbonize transport without battery weight/range limitations

Chemicals Production

Feedstock for methanol, synthetic fuels, and various chemical processes.

Impact: Enable circular chemical production

Energy Storage

Long-duration storage for seasonal renewable energy balancing.

Impact: Enable 100% renewable energy systems

2025 Market Status

Major Developments

China: Over 500 hydrogen projects totaling $30+ billion, strong government support through 2026-2030 five-year plan
EU REPowerEU: Target of 10 million tonnes production + 10 million tonnes imports by 2030; 10% of energy needs by 2050
Technology: AI-driven process optimization, more durable membranes, modular electrolyzer designs reducing costs
Projected Growth: Demand expected to grow significantly across transportation, power, industry, and residential heating through 2050

Challenges and Opportunities

Challenges
