What is the heat generation phenomenon of QHe?
QHe is a heat-generating technology with hydrogen quantum diffusion. The diffusion is induced by heating a small amount of hydrogen saturated in nano-sized nickel-based composite material.
QHe’s energy density is more than 10,000 times higher than natural gas
QHe’s heat density per gram of fuel is much higher than that of chemical reactions such as methane (natural gas) and hydrogen combustion. With QHe, less than 10 grams of hydrogen are needed to power the monthly electricity and heat needs of a household.
QHe can run continuously following initial absorption of hydrogen
In one of our experiments, excess heat was observed for 589 days from May 7, 2021, to Dec. 18, 2022, with hydrogen saturation only at the beginning of the experiment.
Potential of QHe
QHe can provide industrial-scale heat up to 1,000°C. The technology operates with nano-sized nickel- based composite material and a small amount of hydrogen. The technology has been developed with Tohoku University, the top runner in this field. QHe is a breakthrough technology for the world to go net-zero.
Clean Planet is currently engineering QHe-powered heat modules that can provide energy to the industrial, commercial, transportation, and residential sectors. Clean Planet is developing a pilot industrial boiler with Miura Co., Ltd., the Japanese leading industrial boiler company, using QHe-powered heat modules as the heat source to market boilers in a near future.
QHe-powered heat modules are applicable to power generation, manufacturing factories, steel and chemical industries, agriculture, direct air capture, and water desalination.
