In the United States, sand batteries are also being developed. In this case, silica sand is heated to 1200°C and stored in an insulated concrete storage facility. When converting this heat into electricity, water is heated to produce steam, which turns a turbine with many blades. This turbine is connected to a generator, which produces electricity. When generating electricity from heat, this equipment is necessary.
These are the methods of power generation and storage in Prout Village. Next, I will look at existing power generation methods and the reasons for not using them.
One of these is hydrogen. While hydrogen does not emit carbon dioxide when used as fuel, it is released during the production process. For example, producing hydrogen from fossil fuels like natural gas, oil, and coal emits large amounts of carbon dioxide and will eventually lead to resource depletion, making it an unsuitable option.
There is also a method of obtaining hydrogen by electrolyzing water using electricity from natural energy sources like solar and wind power. Although this method has low carbon dioxide emissions, it requires a large amount of water, which could exacerbate water shortages already accelerated by global warming.
