Excerpt
Excerpt Abstract: It is examined that the technical feasibility, economies of hydrogen, improvement of the load factor and reduction of the carbon dioxide emission in the case where a hydrogen-refueling infrastructure is developed using the off-peak power in the existing electrical power grid in Japan.
In this paper we examine the technical feasibility and economies of developing a hydrogen-refueling infrastructure using the off-peak power in the existing electrical grid in Japan.
4.2.2 Electricity cost for water electrolysis
All electric power companines in Japan set up an electricity cost scheme classified with both searons and periods of time in a day in order to promoter the consumption of off-peak power and repress that of peak power. For example Tokyo Electric Power Company, which is the biggest electric power company in Japan, sets up an electricity cost scheme as shown in Table 4{23}. The time in a weekday is divided into three periods. The electricity cost is set up most expensive when the electricity demand becomes hihgest as peak load. On the other hand, the electricity cost is set up cheapest in the nighttime when the electricity demand becomes lowest as off-peak load. On Sunday, the electricity cost is kept constant the whole day and the same as that during the nighttime in the weekday. |
