41.2 Macro Perspective
41.2.1 Methodology
The macro view analysis is based on previously developed model by Aziz et al.
(2017). It is an optimal power planning model covering Kyushu area, assuming a
system that produces and stores hydrogen from surplus power, in combination with
thermal power plants. We expanded the power planning model to include hydrogen
production equipment and storage tanks. Surplus power generation and power mix
were analyzed using the power mix model, shown in Fig. 41.2.
The vertical axis represents the cost of various energy sources while the horizontal
axis represents the hourly time of day. Low-cost nuclear and coal power sources are
