Solar Cogeneration (2011)

Submitted by Raquel Ponte Costa on April 7, 2015

This presentation was created by Paul Davis of Cogenra Solar, Inc. It provides information on solar cogeneration, which utilizes solar thermal alongside a mix of other solar and renewable energy sources to achieve maximum benefits and efficiency.

The most common form of solar cogeneration is electric P.V. combined with solar thermal water heating. The combined system means greater solar efficiency and a higher solar fraction. In turn, this creates higher cost savings for the consumer and a greater reduction of CO2 for the environment.

Solar thermal polygeneration system for cooling, fresh water and domestic hot water supply: Experimental analysis (2014)

Submitted by Francesco Gattiglio on April 1, 2015

In this paper, presented at the World Renewable Energy Congress of London of 3-8 August 2014, a solar-thermal poly-generation system for chilled water for air conditioning using absorption chiller, pure water with membrane distiller and domestic hot water by heat recovery is presented. 

Germany: Feed-in Tariff Changes May Benefit Solar Heat

Submitted by Baerbel Epp on September 22, 2014
Whereas Germany’s total collector sales are dropping, solar thermal companies see a glimmer of hope for big projects because of changed feed-in tariffs in the renewable electricity sector. So far, the cogeneration of heat and power has been the strongest competitor of large-scale solar heat for district heating and industrial projects. Because cogeneration had been a very attractive solution in terms of electricity prices, even a subsidy recovering all costs of a solar thermal investment wouldn’t have tipped the scales in favour of solar heat, a study by Fichtner stated in autumn of 2013. Now, however, cogeneration is starting to lose ground. 
 

Recent Developments in Thermal Driven Cooling and Refrigeration Systems (2007)

Submitted by Raquel Ponte Costa on September 22, 2009

Roberto Best from the Mexican Centro de Investigación en Energía of the Universidad Nacional Autónoma de México produced, in 2007, this paper reviewing recent developments on thermal cooling systems, with special emphasis being added to cogeneration applications. The document also presents results of a study undertook by the same University on absorption cooling systems and ejector cooling systems.
