According to the results obtained, higher overall exergy efficiency was found in the ultra-supercritical cycle because of lower coal consumption. The energy efficiencies of the subcritical, supercritical and ultra-supercritical thermal power plants were determined to be 41.5%, 43.8% and 46.0%, ...
1. Although the proportion of thermal power in all power production has generally declined between 2016 and 2020, it still accounts for more than 70%. Therefore, China’s power generation industry is still highly dependent on a stable supply of thermal coal. Due to the wide scope of business...
(International Energy Agency). Natural gas and coal were introduced into the energy mix around 2008, and wind and solar energies were added around 2015. In 2017, oil made up about 76% of the total primary energy supply, natural gas about 16%, biofuels and waste about 3.7%, wind and ...
Since majority of electricity in China is generated from coal and natural gas, the study carried out WTW analyses for battery electric vehicles (BEVs) using China's various thermal power generation technologies and compare their total energy use and GHG emissions against gasoline or diesel internal...
