Solar Thermal Solutions in Boston and the Northeast (2008)

Submitted by Raquel Ponte Costa on June 13, 2015

This PowerPoint was developed by KeySpan in 2008. It covers why they promote solar thermal water heating in the Northeast, applications, market barriers and a forecast for the future. The presentation introduces the different solar thermal programs that KeySpan offers including domestic hot water, pool heating, space heating, process hot water and solar assisted cooling. It also mentions the different applications where all this solar thermal energy can be used and what type of savings will be seen.

Canada Shines With Solar Expertise (2010)

Submitted by Raquel Ponte Costa on June 13, 2015

This paper was released by Foreign Affairs and International Trade Canada in 2010. The Vancouver Olympic Games showed large-scale success of solar thermal energy in Canada. Solar thermal modules supplied energy that supplied the Vancouver Olympic Village buildings and utilized it for other purposes. Estimates say that the buildings achieved 30 to 70 percent greater energy efficiency compared to standard buildings built to minimum code.

Italy: First Solar District Heating System, 990 m² big

Submitted by Baerbel Epp on June 1, 2015
VareseFinally, solar district heating has reached Italy too: Utility Varese Risorse, which is part of the environmental multi-utility group A2A, brought its solar thermal plant into operation on 19 May. The idea for this project, which also came about thanks to support from Intelligent Energy Europe project SDHplus, was from 2013 when the utility began to show interest in using solar to lower the natural gas consumption of its district heating grid in summer. Staff members of Varese Risorse took part in the SDHplus training course and benefitted from initial feasibility calculations for the solar plant. The collector field of 990 m² has been set up across eight collector rows, seven of which were mounted onto the ground, and one onto the roof of a small technical building, which also houses the heat exchanger and the control unit (see photo).

This report was created and published by the Partners for Climate Protection (PCP). It highlights an important and successful greenhouse gas reduction project from the town of Okotoks, the Drake Landing Solar Community.

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.

France, Italy and Brazil: Programmes for Dedicated Solar Heating and Cooling Conferences

Submitted by Baerbel Epp on May 22, 2015
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.
