Biomass grows during photosynthesis by converting CO 2 and H. Introduction to Biomass It is a renewable energy source because we can always grow more trees and crops, and waste will always exist. nature of the (predominantly biomass) energy resource base, the char-acteristics of the household and community economy, the features of energy policy, and the position of women in families and communities. Through the process of photosynthesis, chlorophyll in plants captures the sun's energy by converting carbon dioxide from the air and water from the ground into carbohydrates, complex compounds composed of carbon, hydrogen, and oxygen. When burned, the energy stored in biomass is released to produce heat or electricity. Nearly 25% of its primary energy comes from biomass resources, and close to. Forestry and agriculture converts solar energy, water and CO2 to biomass Perennial grass for silage. Biomass Energy. But actual availability hardly exceeds 2000 MW. Biomass contains energy first derived from the sun: Plants absorb the sun’s energy through photosynthesis, and convert carbon dioxide and water into nutrients (carbohydrates). Biomass pelleting ANDRITZ designs and builds key process machines, as well as complete biofuel pellet plant solutions for the global renewable energy sector. Using Biomass as an Energy Source There are many ways of using biomass to produce energy. In March, 2013 the former NASA scientist James Hansen (of the 350 ppm limit fame) published a paper showing that nuclear energy has saved a total of 1. For a biomass power station making electricity, it's pretty much like a fossil fuel power station: For other biofuels, we may burn it to get the heat for our home, or burn it to get energy for a car engine, or for some other purpose.
