On average, biomass is made of 75% carbohydrates and 25% lignin.

7. Bioenergy: Bioenergy or biomass energy is any fuel, electric power, or useful chemical product derived from organic matter.
Bioenergy can be derived either directly from the plants or indirectly from plant-derived wastes and residues. Energy is derived from the plants when they absorb energy on land and that energy is naturally recycled during the plant’s life until it is radiated away as low-temperature heat. Biomass energy is captured when the energy is being stored as a fuel.

Burning biomass generates no more heat or carbon dioxide than would be generated from natural processes. As long as the consumption of biomass doesn’t exceed the natural level of recycling, it is a renewable energy source that does not disturb the natural biogeochemical cycle.

10. Reliability The United States has an estimated 65-90 billion tons of dry matter.
At 2000 energy use levels, this biomass could supply 14-19 years of energy.
The Department of Energy states that all of the biomass available now has an energy content that would produce an estimated 2,740 Quads.
1 Quad = 1,000,000,000,000,000 Btus Btu = British Thermal Unit = A unit of heat energy equal to the heat needed to raise the temperature of one pound of water from 60°F to 61°F at one atmosphere pressure.

The price of 5 cents per kW hour of electricity has the potential to supply 4% of power in Illinois, which is almost 700,000 households. At 6 cents a kWh the potential is to supply more than 40%.

26. Gasification Two processes:
Pyrolysis – releases volatile compounds of the fuel
Bigger role here than in coal fired plants
Char Conversion – carbon remaining after pyrolysis reacts with steam and/or oxygen (combustion)
Biomass has high reactivity
Gasification is the process that converts raw solid biomass materials to a clear fuel gas. The gas can be used to power gas turbines, fuel cells, or reciprocating engines.
Dept of Energy
http://www.eere.energy.gov/biopower/technologies/index.htm
Biomass fuels have 70-86% volatile components, where coal only has 30%. Therefore, pyrolysis is a larger role in biomass gasification than in the coal process. Because of the high reactivity of the biomass fuel, all of the biomass fuel is generally converted to gasification products in one pass through the system.

38. Disadvantages of Gasification Some biomass plants have closed because of deregulation of the electric utility industry.
Hard to compete with cheaper sources, such as coal, oil, and nuclear.
Small amounts of tar are released in the gas. The tar can coat parts of the pipe or the equipment.
Catalyst reactor has been developed to decrease the amount of tar to parts-per-million.

41. Costs Capital costs of building a biomass-fired steam turbine plant is about $2000-2500 per KW of installed capacity.
These costs are expected to decrease in the future. The high capital cost is a function of small plant size. The small plant size also increases operating costs in terms of capacity per employee.

If the cost of the process decreases as expected, it will be able to compete economically with current energy sources.
