Total ordered capacity for J-series gas turbines currently exceeds 25 GW globally, the Japanese manufacturer said. One hundred units have been technically selected in Brazil, Canada, Japan, Mexico, Peru, South Korea, Taiwan, Thailand, and the United States.
MHPS chief executive pointed out the J-series “ran all those [one million] hours with 99.5% reliability. Our extreme reliability is not by good luck,” he underlined. “It is because we test the durability and reliability of every new technological advancement for 8,000 hours before shipping it to our customers.
The first J-series gas turbine was installed at T-Point, MHPS own own combined cycle power plant in Takasago, Japan. The developer now built T-Point e, where the air-cooled 60 Hz JAC, has just synced to the grid and achieved full load.
Aiming for 100% hydrogen capability
The turbine can run on a 30:70 hydrogen and natural gas mix, with full hydrogen capability under development. This makes J-series turbines ideal for retrofits of ageing coal-fired turbines, like at the 1.9 GW Intermountain Power Plant in Utah, U.S.
The plant operator last month ordered two JAC gas turbines that will partly run on hydrogen. The initial 30% hydrogen co-firing will reduce carbon emissions by more than 75%, compared to the same size coal-fired power plant, and the 100% hydrogen system will eliminate emissions entirely.
Compared to the same size coal-fired power plants, one million J-series operating hours has resulted in CO2 emissions reduction of 270 million tons. According to MHPS calculations, this is equivalent to CO2 emissions from 1,346,918 railcars of coal burned.
In Utah, MHPS is developing grid-scale renewable hydrogen production and storage in the city of Delta. MHPS Americas chief executive, Paul Browning, announced: “Going forward, every gas turbine we sell globally will have renewable hydrogen fuel capability. This allows our customers to purchase a natural gas power plant today, and convert it over time into a renewable energy storage facility.”
