In 2018, renewable electricity generation rose 7%, with wind and solar PV technologies together accounting for 60% of this increase. Although the share of renewables in global electricity generation reached 26% in 2018, renewable power as a whole still needs to expand significantly to meet the Sustainable Development Scenario share of half of generation by 2030.

Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and municipal lighting, before ...

Hydrothermal carbonization is a chemical process for the conversion of organic compounds to structured carbons. The process, which technically imitates the brown coal formation taking place in nature within 50,000 to 50 million years within a few hours, was investigated by Friedrich Bergius and first described in 1913.

Historical background. Coal liquefaction originally was developed at the beginning of the 20th century. The best-known CTL process is Fischer–Tropsch synthesis (FT), named after the inventors Franz Fischer and Hans Tropsch from the Kaiser Wilhelm Institute in the 1920s. The FT synthesis is the basis for indirect coal liquefaction (ICL) technology.
