Rising demand for solar heat in large buildings and industry

Submitted by Baerbel Epp on June 6, 2018
SHW 1By the end of 2017, the market for solar heating and cooling had grown by 472 GWth, which again made it the largest for solar energy in the world. The one for photovoltaic systems gained 402 GWp to become the second-largest, and 5 GWel was enough for concentrating solar power to rank third, according to the latest Solar Heat Worldwide report. The report also highlights the rising use of megawatt-class solar heating and cooling solutions for large public and residential buildings, as well as factories. It was launched at the end of May by the IEA Solar Heating and Cooling Programme (IEA SHC). Lead author is the Austrian research institute AEE INTEC.

Energy efficiency funding in Bosnia and Herzegovina

Submitted by Baerbel Epp on May 11, 2018
Map: lonelyplanet.comThe Jugoslav Wars of the 1990s slowed down the rate of energy-related retrofits in the residential and public sectors of Bosnia and Herzegovina. Recently, however, the country has seen some improvement in the amount of funding available for clean heating technologies, such as solar thermal, biomass boilers and heat pumps. In early April, the European Bank for Reconstruction and Development, or EBRD for short, provided MKF Partner, a Bosnian microfinance institution, with EUR 5 million for low-interest loans and grants to make residential buildings more energy-efficient. It was the second time the EBRD had allocated funding to financial institutions in the country. Last November, EUR 17 million went to three Bosnian banks, as part of the EBRD’s Green Economy Financing Facility.

How to identify suitable areas for SDH

Submitted by Baerbel Epp on May 9, 2018
Chart: Hamburg InstitutThough the availability of areas for large solar district heating plants remains a major point of contention, there are ways to expand the market. They include detailed local heat plans, the use of unconventional, e.g., polluted or contaminated, areas, and awareness raising among public and private stakeholders. A webinar organised as part of the Horizon 2020 project SDHp2m…from Policy to Market put a spotlight on these topics in February. A recording of the session is available online.

Record participation at SDH 2018 in Graz

Submitted by Baerbel Epp on May 3, 2018
Photo: Climate and Energy FundThe 5th International Solar District Heating Conference, which took place in Graz, Austria, in mid-April, brought together 350 experts from 33 countries. It had twice as many attendees as the previous one in Billund, Denmark, in 2016 and attracted representatives from several development banks, such as the German KfW, the London-based European Bank for Reconstruction and Development and the World Bank via its group member International Finance Corporation, or IFC. The photo shows the conference’s supporters and its three organisers, namely Christian Fink (second from left), Austrian research institute AEE INTEC; Thomas Pauschinger (fifth from left in the back), German research institute Solites; and  Werner Lutsch, Managing Director of the German Heat & Power Association, or AGFW for short (second from right).

Parabolic trough collector production line shipped to China

Submitted by Baerbel Epp on April 24, 2018
Photo: AbsoliconAbsolicon, a Swedish supplier of concentrating solar thermal technology, has recently delivered its first production line to a Chinese company. The equipment to manufacture parabolic trough collectors, which the Swedish business developed in-house, arrived in China in mid-April. The line is now being set up at Heli New Energy Technology, in the country’s southwestern province of Sichuan. The photo, which dates from December 2016, shows the partners involved in the project after they signed the purchase agreement for the system. Heli New Energy is a joint venture between two Chinese companies, namely Xinkun, a family-owned manufacturer, and Jointeam, an energy project developer.

Sweden: Pioneer of solar district heating

Submitted by Baerbel Epp on April 13, 2018
Chart: Sven WernerWhen it comes to district heating, Sweden has made the switch from fossil fuels to biomass and waste heat (see chart). As early as 2015, biomass provided 46 % of the energy in district heating networks across the country, followed by 24 % from waste incineration and 8 % from industrial excess heat. Fossil fuels came only to about 7 % of the around 175 petajoules, or PJ, produced in Sweden in 2015 (latest data available). These percentages, and the chart, were taken from a 2017 paper titled District heating and cooling in Sweden, written by Sven Werner, Professor Emeritus at the Swedish Halmstad University. Sweden is one of the participating countries of Task 55 Towards the Integration of Large SHC Systems into DHC Networks of the IEA Solar Heating and Cooling programme. The researchers plan to publish a report with country portraits of selected solar district heating markets in 2019.

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.

Daylight and electric lighting: new research initiative

Submitted by Baerbel Epp on February 14, 2018
Task 61The IEA Solar Heating & Cooling Programme has approved Task 61, a new research initiative concentrating on integrated daylight and electric lighting solutions. The task will tackle unresolved issues and challenges of a growing market which meets 19 % of the total electricity demand around the world. It will launch with a 3-day workshop from 28 February to 2 March 2018 in Lund, Sweden. Experts with a background in R&D or manufacturing are welcome to join the initiative.

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

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.
