This will also reduce the impact of global warming caused by greenhouse gases. In addition, the combination of coal and biomass will increase the efficiency of gas turbines by 33 to 37%. This was announced by the National Energy Laboratory.

Meanwhile, carbon dioxide will cause global warming. The biomass contribution in this method supports carbon neutral effects, meaning that plants will reabsorb carbon dioxide for the photosynthesis reaction.

Website design By BotEap.comGasification is a method that converts carbonaceous feedstock into gaseous fuels using high temperatures. The gasification process produces synthetic gases such as carbon dioxide, carbon monoxide, methane, and hydrogen. The gasification products go through several stages before being used for energy production. Heat exchanger and scrubber are used for cooling and cleaning.

Website design By BotEap.comGasification products can be converted into energy by direct combustion, as in gas turbines. In this equipment, gas is burned and the turbine rotates. The generator is connected to convert into electrical energy. In fuel cell system, synthetic gas such as hydrogen and methane are used as raw material for fuel cells. Chemical processes take place in the fuel cell stack and produce electricity. Another synthetic gas conversion process is the Fischer-Tropsch, which is extracted from gas to liquid fuel.

Initially, organic material such as biomass, cow manure accumulates in the digester (reactor). The bacteria will extract it into gas through two stages.

Website design By BotEap.comFirst stage, organic material is degraded into weak acid using acid-forming bacteria. These bacteria break down the garbage at the level of hydrolysis and acidification. Hydrolysis is a breakdown of complex compounds or long chain compounds such as fats, proteins, carbohydrates into simple compounds. Meanwhile, acidification creates simple compounds from acid. Change the material into amino acid. The second stage is anaerobic digestion, which forms methane from methane-forming bacteria. This methane gas can be converted into electrical energy using gas turbines or fuel cells.
