China's domestically developed gas turbine Jupiter I, the world's first 30MW-class pure hydrogen gas turbine, has on Sunday achieved pure hydrogen power generation and maintained stable operation in north China's Inner Mongolia Autonomous Region, offering a key solution for renewable energy storage and utilization.
The gas turbine Jupiter I is the world's largest single-unit power pure hydrogen generator, capable of converting hydrogen from storage tanks back into electricity during peak demand periods, according to the Mingyang Group.
It has effectively solved the problem of consuming surplus electricity from new energy sources, and provides an integrated solution that is feasible and scalable for building a new energy system with new energy as the main power source. It has been selected as one of the first batch of national-level hydrogen energy pilot projects in the energy field.
"Compared with a thermal power unit of equivalent capacity, the Jupiter I pure hydrogen gas turbine reduces carbon emissions by more than 200,000 tons annually. In combined-cycle operation, it generates 48,000 kilowatt-hours of electricity per hour, which can meet the daily power needs of 5,500 households," said Wang Yongzhi, general manager of Mingyang Hydrogen Gas Turbine Technology.
The project will effectively mitigate fluctuations in renewable energy output, enhance grid regulation capabilities, provide a replicable model for energy transition practices, and contribute to building a national-level hydrogen energy demonstration zone, according to its operator.
Renewable energy installations in China account for over 50 percent of the nation's total power generation capacity. The country has pledged to peak its carbon dioxide emissions by 2030 and achieve carbon neutrality by 2060.

A group of Japanese gathered in Tokyo on Sunday to protest against the country's record defense budget plan and demand the government led by Prime Minister Sanae Takaichi to curb the military expansion.
Japan's draft defense budget was set at a record 9.04 trillion yen (about 58 billion U.S. dollars) for fiscal 2026, local media reported Friday.
The figure exceeds the previous record initial budget of 8.7 trillion yen for the current fiscal 2025 starting in April and is in line with Japan's defense buildup plan to allot about 43 trillion yen to defense outlays from fiscal 2023 through 2027.
The Sunday protesters held banners and chanted slogans at downtown Tokyo, urging the Japanese government to adhere to its commitment to the pacifist constitution, which renounces the nation's right to engage in war or to resort to military force to resolve international conflicts.
"We oppose the Takaichi administration's massive military buildup and its tough and belligerent rhetoric. The Liberal Democratic Party and its current coalition partner, the Japan Innovation Party, claim that expanding military buildup will bring peace. But they actually seek personal gains from the profits of the military-industrial complexes of Japan and the United States. This is wrong. They want to swiftly abolish Article 9 of the Constitution, while we must take action to protect it," said a protester.
"Germany and Italy have both reflected on World War II. Japan now has Articles 9 of the Constitution, which clearly outlaws war and prohibits Japan from sending troops to other countries. Therefore, Japan's Diet and the state must be strictly bound by the Constitution," said another protester.
A demonstrator said the Japanese government's military buildup and erroneous remarks regarding China have damaged the friendship between the two countries and indicated a worrying anti-China attitude.
"Japan's continuous increase in defense spending not only diverts funds from people's livelihood but also constitutes preparations for war. We don't want it. I am very sad about the trouble Takashi's remarks have caused to the Chinese people. But I hope that at least friendship between the people of the two countries can be maintained. If the Japanese government incites its people to oppose and criticize China, it is truly embarking on the path to war," she said.
