Our Project: "TriMa – Trigeneration Market"

The Research Project „Advancing the Market Penetration of Trigeneration in Urban Region as Contribution to the Energy Revolution (TriMa - Trigeneration Market)” of the Technische Hochschule Nürnberg Georg Simon Ohm (Nuremberg Institute of Technology) and their research partner ENERGIEAGENTUR nordbayern GmbH (Energy Agency of Northern Bavaria) aims to analyze and illustrate the obstacles to the implementation of Trigeneration (CCHP). 

Trigeneration is a future oriented and highly efficient technology for climate protection, which could despite of the advantages not penetrate the German Market so far. During the project, various approaches and measures to overcome the resistance to the implementation of Trigeneration will be developed together with partner from industry, associations, energy provider as well as the user of Trigeneration. The technology provides a way of cooling from the use of heat sources and existing heat network. The implementation of Trigeneration often results in an economic advantage and potential success factors for the user, which is often not widely known. Therefore, it can foster climate protection in municipalities and has high potential for a cost-efficient and wide-spread emission reduction. 

The overall goal of the research project is to increase the usage of Trigeneration technology in order to reduce the demand of electricity for cooling procedures. Currently, mainly compression refrigeration chillers are used for cooling. The substitution of the demand of electric power for compression refrigeration chiller by Trigeneration results in higher capacities of plannable and flexible usable electricity. The CHP power plant output can be planned and used to cover the residual load, i.e., the rest demand of regulated power plants. Additionally, it can be used as compensation to the highly fluctuating and unstable capacities of renewable energy as solar and wind power sources. All relevant actors will be supported with the market penetration of Trigeneration in order to reach the goal, whereas municipalities are the focus group due to their position as energy provider.

The partner from energy industry are the energy supplier companies infra fürth gmbh in Fürth (www.infra-fuerth.de) and N-ERGIE AG in Nürnberg/Nuremberg (www.n-ergie.de).

Associations represented in the project are the Bundesverband Kraft-Wärme-Kopplung e.V. (B.KWK) (www.bkwk.de) and the Green Chiller Verband für Sorptionskälte e.V. (www.greenchiller.de).

The Thüringer Energie- und GreenTechAgentur (ThEGA) (www.thega.de) support the project as well. 

Municipalities included in the research project:

The target groups of the research project are municipalities and companies which work close together with municipalities (e.g. public utilities). Therefore the following eight different municipalities will be analyzed:

  1. Nuremberg (Bavaria, large city, approx. 500 000 inhabitants)

  2. Potsdam (Brandenburg, large city, approx. 160.000 inhabitants),

  3. Jena (Thuringia, large city, approx. 110.000 inhabitants),

  4. Iserlohn (North Rhine-Westphalia, city, approx. 95.000 inhabitants),

  5. Flensburg (Schleswig-Holstein, city, approx. 85.000 inhabitants),

  6. Fürth (Bavaria, large city, approx. 120.000 inhabitants),

  7. Neumarkt i.d.OPf. (Bavaria, city, approx. 40.000 inhabitants),

  8. Meiningen (Thuringia, city, approx. 21.000 inhabitants)
