IEA SHC Task 52: Seeking Cost-optimised Urban Energy Systems

Submitted by Baerbel Epp on May 30, 2015
How can solar energy be ideally integrated into an urban energy system? This has been the key question of IEA SHC Task 52: Solar Heat and Energy Economics in Urban Environments. One and a half years after the task´s start in January 2014, scientists from Germany, Denmark, Austria and Switzerland met in Freiburg for the third task meeting in mid-April to discuss cost assessments of existing plants and models for analysing complex urban energy systems. One of the first published outcomes is a study carried out by Austrian research institute AEE INTEC. It lists the costs of existing solar district heating plants in Denmark, Germany and Austria. The chart shows the preliminary results from levelised heat costs calculated for 29 collector fields of sizes between 500 and 55,000 m² integrated into district or micro grids.

Conference LogosSolar thermal professionals who have taken an interest in solar district heating, in solar air conditioning or the Brazilian solar thermal market will be able to participate in dedicated conferences over the next months, namely the 3rd International Solar District Heating Conference in Toulouse, France, on 17-18 June, the 6th International Conference on Solar Air Conditioning in Rome, Italy, from 24-25 September and the 3rd Brazilian Solar Heating Congress in São Paulo, Brazil, between 2-3 September. All three events have already released their conference programme.
 

Spain: Study Demonstrates Technical and Economic Viability of Barcelona’s Solar District Heating Grid

Submitted by Baerbel Epp on May 5, 2015
IDAE studyThe Spanish Institute for Energy Diversification and Saving (IDAE) has finalised its study on the technical and economic viability of incorporating solar thermal technology into urban district heating and cooling networks. The case study was carried out in Barcelona and concludes that solar thermal is a feasible alternative not only technically but economically as well. Until today, there has only been one district heating plant in operation which integrates solar thermal technology. It is called ParcBit and located at the Technological Innovation Park Balear on Mallorca. According to representatives from IDAE, the new study aims at encouraging further investments in solar district heating in Spain.

Germany: Crowd Lending or Cooperatives – Different Ways to Bring Solar District Heating into Focus

Submitted by Baerbel Epp on April 24, 2015
Trier SolarvereinRenewable heat comes out on top whenever it substituted fossil energy, Swiss solar thermal pioneer Josef Jenni stated during the first panel discussion of the conference on district heating with solar and biomass, which was held in the German city of Trier on 16 and 17 April 2015. Organised by the local solar association, Solarverein, it provided a platform for experts from small and medium-sized industrial companies, universities and research institutes based in Germany, Switzerland, France, Denmark, Austria and Luxemburg to work on turning this objective into a reality by focusing on viable business models of renewable use in district heating systems.

Canada: Solar Vision 2025: Beyond Market Competitiveness (2010)

Submitted by Raquel Ponte Costa on March 25, 2015

This report issued by the Canadian Solar Industries Association (CanSIA) gives an overview of the evolution of the solar energy market in Canada until 2025.  The report covers both the solar photovoltaic and the solar thermal sectors.

Solar energy has numerous advantages. It will be economically competitive, will create employment and production costs will be reduced.

For the solar thermal sector, CanSIA believes that by 2025 the solar thermal industry can reach a capacity between 8 GWth and 15 GWth and has identified 3 different scenarios.
