Economy and CO2 Emission on Hydrogen Production via Both Coal Gasification and Steam Methane Reforming:
Importance of Securing CO2 Storage Space Domestically
Summary
This proposal clarifies the cost and CO2 emissions at the time of final use after hydrogen production, transportation, and adds and supplements the contents of the existing proposals [1～4].
Aiming further reducing CO2, an amine absorption process was additionally installed at the boiler outlet, we examined the manufacturing cost and CO2 emissions when the CO2 capture rate was as high as 99.5%. In addition, a similar study was conducted on the hydrogen production process by steam reforming of natural gas. Then, we examined the case of domestic location. Furthermore, the ZC hydrogen cost and the required CO2 storage amount when zero carbon is realized by combining DAC （Direct Air Capture） were calculated. The DAC cost was calculated on the assumption that the DAC process will be implemented in Japan, including the emissions from overseas.
