A way to solve these problems is the production of biogas. Biogas is a combustible gas consisting of methane, carbon dioxide and small amounts of other gases and trace elements. Production of biogas through anaerobic digestion of animal manure and slurries as well as of a wide range of digestible organic wastes and agricultural residues, converts these substrates into electricity and heat and offers a natural fertiliser for agriculture. The microbiological process of decomposition of organic matter, in the absence of oxygen takes place in reactors, called digesters. Biogas can be used as a fuel in a gas turbine or burner and can be used in a hybrid solar tower system offering a solution for waste treatment of agricultural and animal residues. A solar tower system consists of a heliostat field, which concentrates direct solar irradiation on an open volumetric central receiver. The receiver heats up ambient air to temperatures of around 700°C. The hot air's heat energy is transferred to a steam Rankine cycle in a heat recovery steam generator (HRSG). The steam drives a steam turbine, which in turn drives a generator for producing electricity. In order to increase the operational hours of a solar tower power plant, a heat storage system and/ or hybridization may be considered. The advantage of solar-fossil hybrid power plants, compared to solar-only systems, lies in low additional investment costs due to an adaptable solar share and reduced technical and economical risks. On sunny days the hybrid system operates in a solar-only mode with the central receiver and on cloudy days and at night with the gas turbine only. As an alternative to methane gas, environmentally neutral biogas can be used for operating the gas turbine. Hence, the hybrid system is operated to 100% from renewable energy sources 2012 7 Journal of Engineering Science and Technology Review 5 Special Issue on Renewable Energy Systems 4 48 55 campus http://www.jestr.org/downloads/Volume5Issue4/10.pdf Solar-Institut Jülich OPUS4-6396 Teil eines Buches Alexopoulos, Spiros, alexopoulos@sij.fh-aachen.de Biomass technology and bio-fuels: Heating/cooling and power Hauppauge, NY Nova Science Publ. 2013 22 Renewable energy systems : theory, innovations, and intelligent applications / eds.: Socrates Kaplanis and Eleni Kaplani 9781624177415 501 523 Solar-Institut Jülich OPUS4-5720 Konferenzveröffentlichung Alexopoulos, Spiros, alexopoulos@sij.fh-aachen.de; Hoffschmidt, Bernhard, hoffschmidt@sij.fh-aachen.de; Rau, Christoph, rau@sij.fh-aachen.de; Sattler, Johannes, Christoph, sattler@sij.fh-aachen.de Choice of solar share of a hybrid power plant of a central receiver system and a biogas plant in dependency of the geographical latitude Linköping Univ.

The chapter starts with the general theoretical principles of concentrating systems including the description of the concentration ratio, the energy and mass balance. The power conversion systems is the main part where solar-only operation and the increase in operational hours. Solar-only operation include the use of steam turbines, gas turbines, organic Rankine cycles and solar dishes. The operational hours can be increased with hybridization and with storage. Another important topic is the cogeneration where solar cooling, desalination and of heat usage is described. Many examples of commercial CSP power plants as well as research facilities from the past as well as current installed and in operation are described in detail. The chapter closes with economic and environmental aspects and with the future potential of the development of CSP around the world.
