Main article: Hydrogen power
The main component of the new energy storage and transmission system is hydrogen fuel cells. Back in 2015-2016, serial fuel cells were introduced as power sources for mobile phones. For 2023, work is underway on their use in power plants in transport.
The peculiarity of hydrogen fuel cells is that there is a different type of reaction and not thermal energy is released, but electric. This makes such systems safe and easy to operate. An important factor is the low weight of the fuel cells. Lithium-ion batteries are capable of storing up to 260 Wh of energy per 1 kg of weight. In hydrogen fuel cells, this figure is 151 times higher. Such characteristics can give a powerful impetus to the development of electric transport.
The decay products of the operation of the fuel cells are water, in the form of steam, and a small amount. carbon dioxide Moreover, carbon dioxide gas is not released at all if pure hydrogen is used. This allows us to talk about hydrogen as a renewable mineral energy source. Widespread adoption of fuel cells can help reduce SO2 emissions quickly and substantially.
