European researchers have concluded that relying on simulated data instead of measured data can underestimate hydrogen production costs by 36% for users requiring a steady supply, with average underestimates of around 20% being most severe in cloudy climates. “The difference is greater in cloudy climates because, at the time of publication, open-source simulation tools using satellite data have difficulty estimating solar PV energy production when there are cloud cover.”, said researcher Nicolas Jean Bernard Campion pv magazine. “This may be due to the lower temporal resolution of the satellite reanalysis dataset, but also to inherent errors arising from inaccurate cloud modeling in these datasets.” The researchers say this in a new one report in Renewable and sustainable energy assessments that their technical-economic optimization model estimates e-fuel production costs by taking into account optimal investments and system operations per hour. It aims to improve green hydrogen assessments by addressing discrepancies between simulated and measured solar energy profiles. The team also has a open-source collaborative repository to share measured sustainable energy profiles and provide tools for time series analysis and techno-economic assessments of green hydrogen. Campion said the tool and data will improve prefeasibility studies and site screening.
The South Korean government said it was the city of Gyeongju for a 107.9 MW hydrogen project, estimated to cost KRW 771.6 billion ($552.8 million). Construction will begin in March 2024 and completion is scheduled for March 2028. The government said that the “Gyeongbuk Gyeongju Gangdong Hydrogen Fuel Cell Plant” will produce hydrogen from natural gas reform and supply electricity to a nearby industrial complex.
Samsung C&T has collaborated with Korea Southeast Power and the Chungnam regional government to develop a hydrogen hub in Dangjin, South Korea, according to local media reports. The project includes a 900 MW hydrogen fuel cell power plant, a 300 MW BESS and a data center. The power plant will use clean hydrogen from the Dangjin Songsan Terminal to generate carbon-free electricity, which will supply nearby data centers and industrial complexes. The total project cost for the Dangjin Green Energy Hub is reported to be KRW 4.5 trillion.
Topoo has collaborated with Aramco under a joint development agreement to produce blue hydrogen at Aramco’s Shaybah NGL recovery plant in Saudi Arabia. The collaboration will use Aramco’s palladium alloy membrane technology to produce low-carbon hydrogen while capturing CO2, according to a statement from Denmark-based Topsoe.
