Researchers in Spain has found that combining PV power generation with fuel cells and battery storage may help homes considerably reduce their levelized cost of energy. Their simulation reportedly demonstrated homes may also become completely self-sufficient.

    @Hypx@fedia.io My dataset shows that in Ontario the household annual kWh is 5x higher. In addition the seasonal storage requirement is 4.6MWh which makes economics difficult even with H2.

      This study is based on a household in Spain. Different countries will probably need different setups.

        @Hypx@fedia.io The PICEA system is interesting. At ~$100/kWh that would still cost me ~$50000 to get my home through the Ontario winter. Costs still need to come down at least one order of magnitude.

          A hydrogen-base system would get much cheaper per kWh as it scales up. Most of the cost is probably the fuel cell, electrolyzer, batteries, etc. The tanks probably cost very little.
