Lithium-ion batteries and pumped hydroelectric do the brunt of this energy storage work now, and are expected to dominate in the future, along with hydrogen fuel

In the coal mine, belt conveyors (BCs) are deployed to deliver raw coal with energy consumption, which are coupled with the energy system and transportation network in a coal mine. In order to improve the energy efficiency of the BCs, some studies have been conducted to obtain the optimal control of the BC system.

Therefore, clean coal power generation technology is critical to promoting carbon peaking and achieving carbon neutrality before the all-around development of renewable energy (CDCC, 2015). Compared with direct coal combustion, cleaner coal gasification power generation technology will become a priority for energy conservation
