Biomass

Energy conversion of biomass leads to high local value added as it involves many market actors in the supply chain. Biomass means energy storage on the long run. It is the oldest form of renewable energy usage, although not ever applied with the best and environmentally acceptable technique. Biomass suits best for basic and medium power demand as well as in combination with bioas or solar thermal energy systems. Feed input can be all kind of renewable and waste organic solid substances with a rather high content of lignin (wood). It should be assured that renewable material is produced by sustainable forestry. Biomass firing systems are best suited to produce steam. Upgrading wood to produce wood pellets leads to a renewable energy source which is equally flexible comparing to fuel, much more cheaper and environmentally sustainable. It can be used very well for isolated concepts.

Energy efficiency in biomass systems is achieved by combined heat and power generation. If the process temperature level of the clients heat demand is lower than 105 °C Organic Rankin Cycle (ORC) turbines can be applied, which have relatively low operating and maintenance costs. For higher Temperature levels steam turbines or engines are better suited.
