JERA to conduct trial of co-firing ammonia at coal power plant from March to June

Japan's leading power generator, JERA, prepares to cofire 20% of ammonia with coal at its Hekinan thermal power station, in what it stated will be the world's first trial utilizing a large quantity of the gas at a major industrial plant.

The trial, to be conducted with heavy machinery maker IHI , will happen from March 26 to June 19 and is part of JERA's decarbonisation efforts, it stated.

The task, which started in 2021 with small volumes of ammonia at another system at Hekinan, is focused on cutting carbon dioxide (CO2) emissions by changing some coal with cleaner fuels.

Ammonia is mainly made from hydrogen produced from natural gas and nitrogen from the air. It does not release CO2 when burned, however its production releases emissions if it is made with fossil fuels.

Japan, the world's fifth-biggest CO2 emitter, intends to utilize ammonia and hydrogen as fuels for thermal power generation to aid accomplish its 2050 objective of ending up being carbon neutral, though ecologists have actually criticized the relocation as a way to extend the life of dirty coal-fired power generation.

By conducting this demonstration and establishing combustion innovation, we can take the initial step toward promoting zero-emission thermal power plants that do not release CO2, Katsuya Tanigawa, head of the Hekinan power station, told reporters.

JERA wants to gradually increase the ammonia element with a view to eventually reaching 100% in its power plants and has high hopes of pioneering a new way of decreasing CO2 emissions at coal-fired power plants that might be embraced in other nations.

We wish to contribute to the decarbonisation of the whole world through using our innovation in nations and areas where thermal power plants are required, he stated.

JERA, a joint endeavor between Tokyo Electric Power and Chubu Electric Power, plans to utilize 40,000 metric lots of ammonia for the presentation, however did not reveal where it will purchase ammonia from.

JERA aims to start ammonia co-firing on an industrial basis at Hekinan No. 4 system as early as 2027 and a trial of changing 50% of coal with ammonia at No. 5 unit in around 2028.

While success in adjusting power plants to using ammonia might be a development, even if not enough to satisfy anti-coal advocates, considerable obstacles remain - costs, sufficient supply of ammonia, technology to control nitrogen oxide
