$ECTH Biomass History
Biomass is solar energy stored in plant material such as wood through photosynthesis. Although biomass comes in many forms, wood is the best form of biomass to create energy.
Prior to the Industrial Revolution, woody biomass (firewood & charcoal) satisfied nearly all of mankind’s energy needs.
Declining oil reserves, growing environmental awareness and political issues surrounding fossil fuels have renewed the interest in and demand for our original source of energy, biomass.
New technology can maximize the energy output of biomass, particularly through torrefication and densification(pelleting). This neutralizes carbon emissions, making it one of the most desirable sources of energy benefiting our environment and reducing the "green-house" affect.
Historically, open burning of biomass is neither healthy for our environment or makes economic sense. The transportation of unprocessed biomass to the populated centers was often too expensive, and the high moisture content of firewood and inefficient conversion of wood to energy in traditional wood stoves contributed unacceptable pollution. The solution to both problems is biomass products(like pellets), because of the energy density and efficiency of the product. Wood pellets burn at a very high heat with minimal emissions in modern biomass boilers and furnaces.
One seventh of total energy consumption is from biomass which is the main energy resource for over 1.5 billion people in the world. Biomass energy is the only one which has both the property and characteristics (which mean that it can be stored, renewed and transferred) of fossil fuel. It is less restricted by natural conditions. Biomass energy can be transferred to useful thermal energy(hot water, steam), electrical energy and fuel as power by means of direct combustion, gasification, and bio-liquids. High-grade combustible gas like CO, H2 and methane can be formed by the gasification of biomass. Biogas can be produced by anaerobic digestion of biomass and liquid fuel using, for example, thermalization, biochemistry, machinery and chemistry. Biomass energy is the most renewable energy resource in the world. Like a great solar chemical industry plant, it spreads in plants all over land and water throughout the world which transfer continuously solar energy into chemical energy which is stored in the inner part of plants in the form of organic matter.
