The analysis of geological and reservoir conditions of the underground storage of hydrogen,
methane, and carbon dioxide, that are important when choosing rock formations for the …

Hydrogen energy has tremendous potential as a clean fuel in this energy transition. To build
up the full-scale hydrogen energy supply chain, large-scale hydrogen storage is of vital …

Carbon neutrality (or climate neutrality) has been a global consensus, and international
experience exchange is essential. Given the differences in the degree of social …

In this research, a novel combined cooling, heating and power (CCHP) system taking
biomass and geothermal energy as co-feeds is proposed, which is mainly consist of four …

The concept of underground gas storage is based on the natural capacity of geological
formations such as aquifers, depleted oil and gas reservoirs, and salt caverns to store gases …

Geological structures in deep aquifers and salt caverns can play an important role in large-
scale hydrogen storage. However, more work needs to be done to address the hydrogen …

Power to gas technology is an innovative solution to promote the use of renewable energy
technologies, also including e-fuels. This work presents a techno-economic analysis of a …

As a major greenhouse gas, carbon dioxide (CO 2) causes climate warming and weather
changes. On the basis of CO 2 disposal/storage in salt caverns in this study, a new carbon …
