Finnish and German researchers assessed the position of seasonal hydrogen storage for PV prosumer households with a “lowest value” mannequin on the international stage till 2050. They discovered that seasonal hydrogen storage can solely be anticipated in a distinct segment, off-grid market.
Scientists from Finland’s LUT College and Germany’s Regensburg College of Utilized Sciences are finding out whether or not seasonal hydrogen storage (SHS) may very well be an economical resolution for maximizing photo voltaic self-consumption within the coming a long time. .
The workforce carried out a worldwide evaluation of 145 areas from 2020 to 2050 in five-year increments underneath a “least value” mannequin. They simulated a residential rooftop PV system with SHS utilizing LUT-Prosume software program. The evaluation consists of detailed projections for element prices of the SHS system obtained from numerous sources. The elements of SHS embrace water electrolyzer, hydrogen compressor, storage tank, and gas cell.
The examine considers whether or not SHS prices are optimized for on-grid or off-grid operation in eight residential self-consumption eventualities. Others embrace electrical autos, lithium-ion battery storage, and ground-source warmth pumps for house and water heating.
The outcomes present that SHS can solely be anticipated in a distinct segment off-grid market, in areas restricted to North America, Northern Europe, and Northwest Eurasia. Lebanon, Kuwait, Bahrain, and Qatar may even see a small quantity of SHS capability, in accordance with the examine. The southern areas of Canada, Scandinavia, or the Baltics present a comparatively small SHS capability of lower than 1,000 kWh.
“It’s assumed that the areas with much less hydrogen power storage capability are smaller when it comes to which the SHS with the smaller capacities is cheaper than a standalone PV and battery system,” stated the researcher.
Notably, SHS shouldn’t be the least value choice in any of the investigated areas for on-grid eventualities.
“Excessive funding prices and low effectivity of changing electricity-to-hydrogen-to-electricity via a water electrolyzer and gas cell are main drawbacks for a profitable introduction as a seasonal storage choice in photovoltaic prosumer techniques,” the scientists stated.
They share their findings with “Seasonal hydrogen storage for residential on- and off-grid photo voltaic photovoltaics prosumer functions: Revolutionary resolution or area of interest marketplace for the power transition to 2050?,” which was just lately revealed in Utilized Vitality.
