The largest integrated PV-hydrogen storage project of China has finished construction in Jiangsu, the East China province. The project has an overall photovoltaic capacity of 400 MW and is comprised of a newly constructed 220 kV onshore booster station, a hydrogen production facility having a capacity of 1,500 standard cubic metres per hour and also an electrochemical energy storage station.
The project accomplished two major objectives for the first time – 50% green hydrogen co-firing as well as 100% pure hydrogen combustion. The facility allows for the complete mixing and burning of hydrogen as well as pulverised coal within the boiler. It attains the first application of hydrogen co-firing in the world at a 50% heat input ratio within a 40 MW coal-fired boiler. This technology can decrease the use of coal and carbon emissions as much as 50% and also greatly reduce nitrogen oxide emissions. It can also enable the utilisation of green hydrogen, if needed, with on-site solar and storage.
Based on pilot projects
It is worth noting that this latest development corresponds to a large-capacity pilot-scale hydrogen-coal co-firing test from Yantai Longyuan Power Technology, which happens to be a subsidiary of CHN Energy Technology & Environment Limited, on June 7, 2026. The test was done at the 40 MW Boiler Clean Combustion Engineering Laboratory of the company.
Apparently, the project employs a completely self-made low-NOx burner for 50% green hydrogen co-firing and also a safety net for the whole process, right from hydrogen delivery to in-furnace combustion.
Green hydrogen is produced by way of using renewable energy like wind and solar, and when it is ignited, it goes on to emit just water, making it a zero-carbon fuel. The project developers happen to say that this accomplishment offers a viable technical path in terms of large-scale reduction of carbon at current coal-fired power plants located in China.
Interestingly, the project will also play quite a significant role in fostering the combined development of coal power and renewable energy along with the green and low-carbon evolution of coal-fired power generation.
