43.7 Summary
This study proposes a Japanese Power to Gas Concept and assumed feasibility of
that. The proposed concept is economically feasible under the specific situation. The
points of feasibility study are as follows:
1. Hydrogen from only “excess” electricity is too expensive even in the future, the
energy cost become higher than the present.
2. Intelligent control of electrolyzer will contribute to lowering the cost of hydrogen.
3. Hydrogen combined heat and power reduces more CO 2 than just supplying heat
from hydrogen, but it depends on CO 2 intensity of grid electricity.
Future analysis includes more sophisticated and realistic simulation of Power to
Gas system, such as using real electricity and heat demand pattern, analysis under
variable electricity price, and analyzing the effect of battery buffer for electrolyzer.
