Innovative biomass power plant based on pebble-heater technology and hot air turbine

The use of biomass for combined heat and power (CHP) production becomes increasingly important. On the one hand it substitutes the usage of fossil fuels like coal, oil or natural gas; on the other hand it is neutral regarding the CO2-emissions into the atmosphere. That is the reason why many countries, especially the EU and the USA have launched very ambitious programs for increasing the usage of biomass, especially for power production.

The European Commission ´s White Paper sets out a Community Strategy and Action Plan to increase RES (regenerative energy sources) market penetration, to reduce energy dependency and to reduce greenhouse gas emissions in order to meet the Kyoto objectives. One of the actions is to install 10,000 MWth of CHP biomass plants till the year 2010. That action will help achieve the objective of 23.5% of electrical power produced from RES. With an estimated annual 14,000 MW of installed power generation capacity worldwide, biomass power is the largest source from non-hydro renewable electricity in the world. Currently, the USA are the greatest bio-power producer with a capacity of 7,000 MW. Approximately 80% of this total are generated in the industrial sector, i.e. in relatively big units in the pulp and paper industry. The US Department of Energy (DoE) has started several programs in order to contribute to a further increase in bio-power (e.g. co-firing, gasification, energy crops etc.). One program deals with the development of small modular systems in the size of 10 to 5,000 kW. Those systems are expected to be attractive with regard to deregulation and the consumers’ free choice of who they want to be their power supplier and what they want the contents of the power product to be. Nevertheless, DoE expects that the biggest markets for biomass power generation worldwide will be the developing countries. China and India are considered to be the prime candidates, followed by Brazil, Malaysia, Philippines and Indonesia. They all meet several criteria, such as rapid economic growth, burgeoning demand for electricity, mounting environmental problems, need for rural electrification and significant agricultural/forestry residues.

Energy from biomass
© Ostbayerische Technische Hochschule Amberg-Weiden (8/2005)
In principle biomass is organically stored solar energy. The storage occurs through photosynthesis in plants and via the plants in animals as well. According to this definition, coal, oil and gas may also be considered as biomass; after all they originate from dead plant and animal residue. As we understand it today, biomass also has a temporal dimension. It is decisive for our climate that the growth process of biomass - while it is converting carbon, mostly from the carbon dioxide (CO2) in the air, into organic matter - closely coincides with the release, e.g. by energetic utilization. This period can last several hundred years for trees and only a few weeks for other plants.

Innovative Biomasseverstromung

Biomasse gewinnt bei der Erzeugung von Strom und Wärme, in Anlagen zur Kraft-Wärme-Kopplung (KWK), zunehmend an Bedeutung. Hintergrund dieser Entwicklung ist die neutrale CO2-Bilanz nachwachsender Energieträger. Gesetzliche Initiativen, wie das Erneuerbare-Energien-Gesetz (EEG), haben dazu beigetragen, die Biomassenutzung auch in wirtschaftlicher Hinsicht als interessante Alternative zur Nutzung fossiler Brennstoffe aufzubauen.
