○Electricity Generation and Storage [5]

     Moreover, deriving hydrogen from natural energy sources like solar or wind power, by electrolyzing water, offers lower carbon dioxide emissions. However, this method requires large volumes of water, exacerbating existing water scarcity issues due to factors like global warming. With the world population projected to increase continuously—from approximately 8 billion around 2020 to an estimated 9.7 billion by 2050 and 10.4 billion by 2080—using water in this scenario would intensify water scarcity issues.

    The process of water electrolysis also involves the use of rare metals like iridium. At the current consumption rate, it's predicted that by 2050, the usage of these metals will surpass the available reserves, making it an unsustainable option.

    Research into extracting hydrogen from seawater is ongoing and could become a viable alternative if accomplished without using rare metals.

    Furthermore, generating gas, electricity, and hydrogen from biomass power generation makes hydrogen the primary energy source. Biomass comprises human and livestock waste, agricultural residues like straw, husks, food waste, wood, among other biological materials. For instance, a household bio-gas toilet can process cow dung, which contains methane bacteria. Adding human waste, food, and weeds to the cow dung ferments it, generating biogas—approximately 60% methane and 40% carbon dioxide. This gas can be used directly for burning or spinning a gas turbine to generate electricity. It can also be purified into hydrogen using steam reforming devices. Small-scale steam reforming devices have been commercially implemented as cogeneration systems. Converting this hydrogen into magnesium hydride enables easy storage and portability.

    A straightforward application of biomass power generation is using gas domestically, avoiding complex setups. Plants consumed by livestock absorb carbon dioxide during photosynthesis and release it as waste, which microbes decompose, generating carbon dioxide. Using this gas as an everyday energy source can be beneficial. As the self-sufficiency rate of food increases in Prout Village, leading to more livestock and subsequently increased animal waste, biomass power generation becomes a substantial energy source.
