2025 timeline suggested
Mitsubishi Power said it is developing a 40 MW class gas turbine system
that directly uses ammonia as fuel for gas turbine power generation.
The company said the decision is in response to the growing momentum for
energy decarbonization around the world and Mitsubishi Power plans to put
the technology into practical use after 2025 through combustion tests. The
practical application of a direct combustion gas turbine using 100%
ammonia fuel at this output scale is unprecedented in the world, and it
can contribute to the promotion of decarbonization in small and
medium-sized power plants such as industrial fields and remote islands,
the company said.

Mitsubishi Power said it has started
development of the world’s first ammonia-fired 40 MW class gas turbine
system Expanded carbon-free power generation lineup, aiming for practical
use after 2025.
“We
are working to reduce the environmental burden by developing highly
efficient power generation technology, and we use natural gas as the fuel
for the gas turbine combined cycle (GTCC), which currently emits the least
CO2 emissions, from natural gas when burning,” the company said in a news
release. “In addition, as part of the utilization of ammonia, we have been
developing a system that reconverts ammonia into hydrogen and nitrogen by
the exhaust heat of the gas turbine and applies it to the hydrogen gas
turbine.”
In the direct combustion of ammonia, it is a challenge to deal with
nitrogen oxides (NOx) generated by the oxidation of nitrogen in the fuel
by combustion, and Mitsubishi said with its H-25 type gas turbine, the
company plans to develop a combustor that reduces NOx emissions and put
into practical use a gas turbine system that combines a denitration
device.
Ammonia, which is a compound of hydrogen and nitrogen, is one of the media
that can efficiently carry hydrogen, and can also be burned directly as
fuel.
“In recent years, ammonia has begun to attract attention from the
perspectives of achieving carbon neutrality through the transition to a
hydrogen-based society and reducing the environmental load of existing
energy, and early on to power generation facilities such as electric power
companies and IPPs (independent power generation companies),” the company
said. “By introducing it to, it is expected to be used as a carbon-free
fuel in the future.”
