JERA and IHI accelerate demonstration of ammonia co-combustion in coal-fired power plant


nd coTOKYO: Japanese power producer JERA and machinery partner IHI Corp said on Tuesday they would present a schedule to demonstrate the co-combustion of larger volumes of ammonia with coal at a large commercial power plant.

JERA’s Hekinan Thermal Power Plant will now begin demonstrating the technology, burning 20% ​​ammonia and 80% coal in its 1 gigawatt No. 4 unit, in the fiscal year beginning April 2023.

Burners, tank and piping were installed ahead of schedule, the two companies said in a statement. JERA is Japan’s largest electricity producer.

The project, which began last year with small volumes of ammonia at another unit in Hekinan, aims to reduce carbon dioxide (CO2) emissions by using cleaner fuels.

This will be the first trial in the world in which a large amount of ammonia will be used with coal in a large commercial plant. The combustion of ammonia does not emit CO2. Other sources of energy are needed to make it, but they can be renewable.

Using this technology, Japan hopes to extend the life of its coal-fired power plants, thereby ensuring both a stable energy supply and a reduction in CO2 emissions.

The country is the fifth largest emitter of CO2 in the world.

Ministers from the Group of Seven countries agreed last week to largely decarbonize their power sectors by 2035.

Ammonia is traditionally used for fertilizers and industrial materials.
