Results showed that the solar and wind power scenarios showed low burdens with 35.3%–39.9% and 22.3%–42.6% of coal power, respectively. The main reason was that solar and wind power reduced CO 2, particulates, and mercury emissions as well as coal consumption, which led to an improvement in human health and resources damage.
The same transition to clean energy is happening at coal plants across the country. In Illinois alone, 11 plants will close over the next three years and be converted to solar farms or battery storage. In Louisiana, where a coal plant closed last year, a new solar farm is planned that could power 45,000 homes.
If solar power was used to replace a significant amount of coal fed to a power plant (operating in ‘coal saver’ mode), the overall amount could actually decrease, although this would not be the case with plants operating in ‘solar boost’ configuration.
Two possible options are explored here: combining solar energy with coal-fired power generation, and cofiring natural gas in coal-fired plants. Both techniques show potential. Depending on the individual circumstances, both can increase the flexibility of a power plant whilst reducing its emissions. In some cases, plant costs could also be reduced.
For coal electricity, mining and washing coal, transport, and power plants' infrastructure were examined, and the technologies used in producing power were subcritical, supercritical, and ultracritical units .
As a result, this article identifies five opportunities to transition coal assets to clean power before 2030. Based on that, it is estimated more than 800 coal power stations in emerging economies show potential to be profitably replaced by solar PV in this decade.
