Tokyo, June 16 (Jiji Press)–Japan’s IHI Corp. <7013> said Thursday that it has successfully cut greenhouse gases by over 99 pct during fuel combustion for power generation by using only liquid ammonia fuel in a 2,000-kilowatt-class gas turbine.

The heavy machinery maker plans to put the technology into practical use in 2025.

Expectations are high for power generation using carbon-free ammonia fuel. A major problem, however, was that combusting a fuel of which 70 pct or more is ammonia generates nitrous oxide, which has a far higher greenhouse effect than carbon dioxide, according to IHI.

The company solved this problem by developing a new combustor, achieving the 99 pct reduction in what it says is the first such achievement in the world.

IHI said it will further improve the operability and durability of the technology toward practical application.
