SDH prefeasibility studies in Bosnia and Croatia

Submitted by Baerbel Epp on May 29, 2018
Source: CoolHeatingIn early 2016, EU-funded CoolHeating began using the know-how acquired during best practice projects in Austria, Denmark and Germany to help with the implementation of small modular renewable heating and cooling grids in southeastern Europe. In mid-March, the CoolHeating partners published seven prefeasibility studies of district heating and cooling across five municipalities in Bosnia and Herzegovina, Croatia, Macedonia, Serbia and Slovenia. Because of geographical features, most projects favoured biomass, but solar thermal does play a crucial role in the proposals created for the Bosnian town of Visoko (see map) and the Croatian city of Ozalj.

First Spanish solar district heating system for 12,000 families

Submitted by Baerbel Epp on May 7, 2018
Source: Ayuntamiento de Alcalá de HenaresIn February, Alcalá Ecoenergías signed a deal to construct a district heating system powered by solar and biomass in Alcalá de Henares, a city in Spain. The agreement between the local company and the municipal government will lead to one of the country’s first-ever large-scale solar district heating systems, intended to provide 12,000 homes with renewable heat. The EUR 38 million investment, of which EUR 32 million have been allocated for biomass and EUR 6 million for solar thermal, near Spain’s capital of Madrid is expected to be completed by late 2019 (see the design study on the left). Several other solar district heating projects are under development.

Big Solar Germany: Utility-scale solar heat at record-low 36 EUR/MWh

Submitted by Baerbel Epp on April 3, 2018
Christian HolterOperators of several gas-driven combined cycle power plants, or CCPPs, have notified the German Federal Network Agency of their systems’ final shutdown. These plants are no longer economically viable, as they have been running ever fewer hours because of a high proportion of cost-effective renewable grid electricity. Their shutdown will create a shortage of supply in district heating networks providing thermal energy to German municipalities. Utility-scale solar thermal plants equipped with seasonal storage could help close the gap at heat prices of around 36 EUR/MWh, Christian Holter said. Holter is the Managing Director of Austrian turnkey system supplier S.O.L.I.D., which has carried out feasibility studies on behalf of several European cities.

NPV, IRR and DDP: The language of bankers and investors

Submitted by Baerbel Epp on March 27, 2018
Chart: Patrick ReiterIndustry professionals often do not use the same language as bankers and investors when they present solar thermal projects. We have asked Patrick Reiter, who has just finished his master’s thesis, titled Solar District Heating – Economic feasibility of large-scale solar thermal systems in municipal district heating networks – a case from Austria, to explain the most important words and key performance indicators, or KPIs, for the financial feasibility assessment of large-scale solar thermal plants. He studied for his master’s degree at the University of Graz’s Institute of Systems Sciences, Innovation and Sustainability Research.

Solar thermal and biomass – a winning solution for district heating

Submitted by Baerbel Epp on March 18, 2018
Photo: Riccardo BattistiBiomass may be cheap and carbon-neutral, but a solar upgrade of biomass-fired district heating could further improve efficiency and reduce local emissions. For example, solar heat helps avoid having to start up and shut down wood-chip boilers or operate them at partial load. It can even replace backup fossil fuel systems, which provide district heating networks with energy in summer. During a December 2017 webinar, held as part of the Horizon 2020 project SDHp2m…From Policy to Market, experts from Sweden and Austria showed promising case studies for a clever combination of biomass and solar thermal in district heating.

Solar district heating on the Roof of the World

Photo: Task 55A contract to set up a solar district heating network in Langkazi county in Tibet has been awarded to Arcon-Sunmark Large-Scale Solar Systems. The Chinese-Danish joint venture signed an agreement with the local government of the autonomous region of Tibet. The system should provide solar district heating for 82,600 m² of floor area and meet 90 % of the yearly space heating demand in Langkazi, the town sharing its name with the county. The system, planned to be set up by November, will consist of a 22,000 m² collector field, 15,000 m³ of pit storage and a 3-MW electric boiler. The sponsor of the pilot project is China’s central government.

Solar to replace coal in Polish district heating networks

Submitted by Baerbel Epp on February 7, 2018
NFOŚiGWZbigniew Kamieński, adviser to the president of NFOŚiGW’s board, has recently made some encouraging statements. During the conference Use of renewable energy sources and seasonal heat storage in district heating in Warsaw on 17 January, he said that the proposal of a new subsidy programme for renewable district heating deserved attention and implementation. The conference with nearly 130 attendees was organised jointly by NFOŚiGW, the National Fund for Environmental Protection and Water Management, and IEO, the Institute for Renewable Energy, and was supported by the SDHp2m project

Project partners guarantee SDH yield

Submitted by Baerbel Epp on December 21, 2017
ADEME15 December saw the inauguration of the first installation supported by the subsidy scheme for large-scale solar thermal projects in France. The 2,340 m² collector field by German manufacturer KBB Kollektorbau has since been feeding into a biomass district heating network of Châteaubriant, a town in western France. Altogether, the subsidy scheme’s administrator, French energy agency Ademe, approved six solar thermal projects during the first tender invitation called Appel à Projets National Grandes Installations Solaires Thermiques. The second one in November 2017 led to the submission and approval of a 14,000 m² solar process heat project, which is currently in planning. The programme inviting large-scale solar thermal tenders started in 2015 (see the database of incentive programmes for more information). There are two new submission deadlines planned for March and November 2018.

EU Funding for Solutions to Decarbonise Heating and Cooling Market

Submitted by Baerbel Epp on November 19, 2017
Horizon 2020A search for ‘solar thermal’ in a recently published 195-page document titled Secure, Clean and Efficient Energy will not return encouraging results (see the attached document). The publication by the Horizon 2020 Work Programme 2018-2020 shows only 6 entries in total. “Solar thermal is definitely not a priority of the new programme,” said Daniel Mugnier, Head of R&D at French engineering services company Tecsol. “And even if the European Solar Thermal Technology & Innovation Platform were to try to promote several hot topics, there’s only one call [LC-SC3-RES-7-2019 on solar process heat] dedicated to the technology.”
 

Italy: Solar District Heating Shows Few Installations but Good Prospects

Submitted by Baerbel Epp on November 11, 2017
Ambiente ItaliaSubstantial solar resources and a generous incentive scheme called Conto Termico 2.0: Perfect conditions, it seems, for the widespread use of solar district heating. But barriers such as a low gas price and the concentration of district heating in a small part of Italy have so far limited deployment to a few installed systems. The map shows the three existing SDH plants in Varese, Sansicario and Lodi (red circles). A fourth with a gross area of about 600 m² is expected to come online in 2020 to feed heat into Turin’s district network operated by the Iren Group utility (yellow cirle).
