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

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

District heating shows lower total socio-economic cost in future energy system

Submitted by Baerbel Epp on January 31, 2018
Costs for ST 1What would the economic impact on a future energy system be if one were to unlock the full solar thermal potential in Austria, Denmark, Germany and Italy? According to a study conducted by Aalborg University as part of the IEA SHC Task 52 research project Solar Heat and Energy Economics in Urban Environments, exploiting the maximum potential will result in significant cost reductions if solar heat is supplied not individually but by district heating. The graph shows small changes of between -0.1 % and +0.2 % in total socio-economic cost both in the District Heating scenario (expansion of district heating grids) and the Heat Savings one (retrofits reduce heat demand in buildings) when the maximum solar thermal potential is realised by using either decentralised solutions or district heating to supply heat to consumers. The key factor influencing the outcome is the cost of solar thermal systems.

Project partners guarantee SDH yield

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.

Kyrgyzstan’s capital sees 0.5 MW SDH plant being built

Submitted by Baerbel Epp on December 19, 2017
Bishkek City HallIn September, the then deputy PM of Kyrgyzstan, Duishenbek Zilaliev, attended the inauguration of a 0.5 MW solar district heating plant in the capital Bishkek. The press release on the event – published by the media and communications department of Bishkek’s city hall on 22 September – also mentioned the operator of the solar field, the Bishkekteploenergo municipal utility, the largest thermal energy provider in the city. The national Environmental Protection Fund supported the project financially by offering a grant of Kyrgyzstani Som (KGS) 10.6 million – 72 % of the total investment costs of KGS 14.8 million (around USD 212,000).

Australia: Think Big, Think Solar

Submitted by Baerbel Epp on December 1, 2017
GreenlandIn Australia, the deployment of large commercial solar thermal plants is picking up speed. This year, Monash University had a solar field of 0.5 MW put into operation and aims to expand it to 1 MW. The solar heat that is fed into the district heating system of the large campus area in Clayton, a suburb of Melbourne, is said to meet the entire heat demand in summer. The field consists of vacuum tube collectors by Australian manufacturer Greenland Systems (see photo) and was designed and installed by the LCI engineering consultancy from Melbourne. Currently, Danish Aalborg CSP is in dialogue with Perth-based Agrimin about the supply of solar process heat to a planned sulphate of potash (SOP) mine and processing factory in the state of Western Australia.

Solar Is UK's Best District Heating Option

Submitted by Baerbel Epp on November 24, 2017
The UK government has clear and ambitious plans to raise the share of district heating (DH) in total heat consumption. GBP (Pound Sterling) 320 million is said to be made available for increasing the number of households connected to DH from 220,000 to 8 million by 2030, or to 30 % of today’s 27 million households in the country. These impressive figures are part of a report called Winning Hearts and Minds – Scenario-Driven Stakeholder Analysis on How to Make District Heating Successful in the UK, a combination of scenarios and online surveys developed jointly by German-based Communication Works and the Stockholm School of Economics on behalf of the UK’s Association for Decentralised Energy. The aim is to find suitable avenues for popularising DH among heat users in the country.

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.”
