Biomass energy aims to sustainably produce fuel and #electricity through organic matter.
Humans have been harnessing #biomass #energy through the fire to grill meat and warm their house. And 2,5 billion people still do.
Here are five well-known processes: #incineration - Biomass is burned to #power a steam engine that powers a generator. This method is quite unhealthy. #fermentation - Bacteria break down the biomass’ glucose to #ethanol. This #biofuel is made from food crops like corn or cellulosic like wood. #gasification - Biomass is converted into biogas by heat and pressure. #pyrolysis - Biomass is heated in the absence of oxygen. The results are three products: #biochar , #biogas , #biooil. Biochar naturally has a high carbon density of 90 - 95%. #biodigestion - Bacteria break down biomass, in the absence of air, creating #biogas and #digestate.
Biomass is a convenient and reliable source of energy simply because where there are humans, there is food and food waste. Therefore the resources needed will always be available. Products like biochar, bio-oil, biogas and digestate supersede and are even better than the hydrocarbons while being renewable. Moreover, the domestic production of bio-oil and gas provides self-sufficiency.
Biomass energy problems though. Ultimately, biochar, for example, is renewable, but to gain the energy within it still has to be burned in the same manner as coal. Hence, the same similar effects, char does not erase entire ecosystems, but air pollution might still be a problem. Furthermore, all of the noted renewable energy sources are carbon neutral to positive, not negative.
To keep it neutral, new trees and plants have to be grown consequently.
If not maintained suitably desertification, loss of biodiversity and deforestation will become unavoidable.
Since #germany is the third highest exporter of agricultural goods and used 50% of its land for farming, Germany would benefit greatly from biomass energy. You can see why Germany is investing so much into biogas plants. Harnessing the power of biofuel does is not only #sustainable and renewable but would also make Germany self-sufficient since nearly 100% of oil and 80% gas
