Technical feasibility of converting abandoned calcite mines into
Combustion of hydrogen is a promising option for reducing carbon emissions but is not yet available as a popular renewable energy source. Hydrogen, as the most miniature molecular weight gas in nature, has a density of only 0.089 g/L at room temperature and pressure, which is 1/14 of that of air [15, 16].Due to its zero emissions
AHP algorithm used to select suitable abandoned underground mines for energy storage
In the energy transition, the promotion of renewable sources entails the development of storage technologies to manage the mismatch between energy production and demand. In this scenario, the use of CAES (Compressed Air Energy Storage) technology enables the efficient and cost-effective storage of large amounts of energy.
