Green Hydrogen Cost Drops Below $2/kg for the First Time: Renewable Electrolysis Achieves Parity with Grey Hydrogen in Some Regions

The International Energy Agency released its latest Global Hydrogen Assessment on December 22, showing global average green hydrogen production cost has fallen to $1.87/kg, crossing the $2 threshold for the first time. In regions with abundant solar resources like the Middle East and Australia, green hydrogen has reached $1.2/kg, roughly matching grey hydrogen's $1.0-1.5 range.

Key cost drivers include electrolyzer costs declining 55% over three years, continued renewable electricity price declines, and scale effects from large projects. The world's largest green hydrogen project, Saudi Arabia's NEOM facility, has been operating at full capacity since 2028 with annual output of 220,000 tons at approximately $1.15/kg.

IEA Director Fatih Birol called crossing the $2 threshold a milestone, meaning hydrogen finally has economic viability for decarbonizing hard-to-electrify sectors like steel, chemicals, and shipping. The IEA projects global average green hydrogen cost will fall to $1.2/kg by 2032, achieving full parity with grey hydrogen in most markets.
