Serbia: EU Supports 903 m² Solar District Heating Installation

Submitted by Baerbel Epp on September 3, 2017
Banat sun 4 all Throughout the last years, the EU has been criticised for many things, and the UK has now been the first to decide on leaving. Still, there are good examples of how the union can benefit even non-member countries. For instance, there is a project called Energy Efficiency – The Premise of a Better Environment in Romania-Serbia Cross-Border Area, which was presented at the Energy Week in Belgrade in mid-June. This joint effort of two cities in the Banat region, Pancevo in Serbia and Resita in Romania, required EUR 1.4 million, mostly financed by the EU as part of the Interreg – IPA CBC Program Romania-Serbia Programme.
 

Lithuania: Can Solar Thermal Beat Low Biomass Heat Prices?

Submitted by Baerbel Epp on August 14, 2017
Lithuania District HeatingWith biomass prices on the rise, solar district heating could become profitable in Lithuania. But without investment grants, payback periods were still too long, it said in the conclusion of a 2015 SDH market study by LEI, the Lithuanian Energy Institute (see the attached document in Lithuanian). The photo shows the country’s first SDH system set up in 2011. Installed on the roof of the boiler house, it preheats water for a wood chip boiler in the district heating station of Dūkštas, a town in eastern Lithuania. The demonstration unit with 82 m² of vacuum tube collectors received funding from international organisations.

Denmark: Concentrating Solar Collectors for District Heat in Northern Europe

Submitted by Baerbel Epp on August 11, 2017
BronderslevBrønderslev, a Danish municipality with a population of 12,500, is setting up a multi-purpose renewable heat plant for their district heating network. So far, local utility Brønderslev Forsyning has been operating seven gas-fired combined heat and power (CHP) plants and two gas boilers to produce 130 GWh of heat each year. In the future, most of the yearly district heating demand is planned to be met by a new Organic Rankine Cycle (ORC) unit which receives its energy from two wood chip boilers with 10 MW each and from a 16.6 MWth parabolic trough collector field with a mirror area of 27,000 m².

Germany: Tool to Calculate Solar Feed into District Heating Network

Submitted by Baerbel Epp on August 1, 2017
Map District Heating in GermanyInterest in solar district heating is growing in Germany. A map by German research organisation Solites shows the systems currently in operation to be 23 totalling 49,600 m² of collector area (34.7 MWth). Last year saw the addition of four installations with a combined area of 12,921 m²; one of them was Germany’s first record-size solar district heating plant in 11 years, in Senftenberg. Solites has now developed a tool to calculate the yield of SDH plants. Called SCFW 2.0 (ScenoCalc Fernwärme 2.0), it is available as a free download at www.scfw.de and is hoped to increase transparency by improving the comparability of solar district heating plants and solutions.

China: Sunrain Finalises Strategic Cooperation Agreements

Submitted by Baerbel Epp on June 30, 2017
Natural Ressources CanadaThe Chinese Sunrain group, the world’s biggest collector manufacturer, is broadening its product portfolio to include large-scale solar thermal plants. Sunrain had already made the first step towards globalising its strategic partnerships by establishing a joint venture with Danish-based Arcon-Sunmark in June 2016. It has now concluded a cooperation agreement with CanmetEnergy in Canada with the aim to develop solar district heating systems using borehole heat storage fields for seasonal storage in China. Canada’s Minister of Natural Resources Jim Carr (back row 2nd from left) oversaw the signing of the agreement during his visit to China in June 2017. The agreement was signed by Xinjian Xu, Founder and Board Chair of Sunrain Solar Energy (front right) and Frank Des Rosiers, Assistant Deputy Minister of Natural Resources Canada’s Innovation and Energy Technology (front left).

IEA SHC: Solar Heat Worldwide Highlights Remarkable Achievements and Addresses Challenges

Submitted by Baerbel Epp on June 2, 2017
Solar Heat Worldwide TitleIn late May, the IEA Solar Heating and Cooling Programme (IEA SHC) published its annual report titled Solar Heat Worldwide (see the attached document). It is the most comprehensive study of solar heating and cooling markets around the globe and has been referenced by international organisations such as REN21 and IRENA. Based on data from 66 countries, the most recent report has grown from 76 pages in 2016 to 86 in 2017. It includes a new section which highlights last years’ encouraging market development of megawatt systems for solar district heating and solar process heat and a second part providing in-depth figures about the national and global markets of 2015.
 

IEA Task 55: Solar District Heating Means Big Business

Submitted by Baerbel Epp on May 23, 2017
Task 55Solar district heating is attractive business. Not only does this become obvious when looking at the 347 MWth of newly installed SDH capacity in Denmark in 2016, but also when one hears about Big Solar, a 250 MWth collector field – with 1.8 million m² of seasonal storage – planned to cover 20 % of the energy demand in the Austrian city of Graz by 2020. It certainly explains the high interest in international research platform Towards the Integration of Large SHC Systems into DHC Networks, or Task 55 of the IEA Solar Heating and Cooling Programme. “We welcomed 33 participants from eight countries during our second project meeting in Aalborg in mid-March, and even had to limit the number of participants per company because of the huge demand,” explained Sabine Putz, Operating Agent of Task 55 and COO and Head of R&D at S.O.L.I.D.

Netherlands: Solar Thermal Benefits from SDE+ Solar Heat Tariff

Submitted by Baerbel Epp on May 1, 2017
District Heating Workshop NetherlandsIn the Netherlands, solar district heating plants with a capacity of 140 kWth or above can benefit from a feed-in tariff scheme called SDE+, which pays a certain amount per kWh of energy. Under the scheme, operators of renewable energy plants can apply for a subsidy to bridge the gap between market price and cost of energy production. Consequently, interest was high when a workshop about solar district heating (SDH) took place in mid-April 2017. It attracted around 50 people from the district heating and the solar thermal industry, consulting businesses and the government. Organised jointly by Dutch district heating organisation Warmtenetwerk, Holland Solar and the Netherlands Enterprise Agency, RVO.nl, the workshop featured a presentation on SDH in Denmark – held by Jan Erik Nielsen from PlanEnergi and based on results from Task 45 and 55 of the IEA Solar Heating and Cooling Programme – and provided information about the national subsidy scheme, thermal storage technologies as well as the only DH plant in operation in the Netherlands to date.

IRENA: Renewable District Heating and Cooling Roadmap to 2030

Submitted by Baerbel Epp on April 27, 2017
District Heating PotentialThe International Renewable Energy Agency (IRENA) has published an industry roadmap for Renewable Energy in District Heating and Cooling (DHC) as part of its REmap 2030 project. This study analysed the current state of the DHC market in eleven countries – with a focus on district heating in seven and one on district cooling in the other four – and examined the long-term potential of the two technologies in these countries (see the attached PDF). The countries chosen for the study have distinctly different market environments. Two of them are Denmark and Switzerland, which have had the highest share of renewables in their energy supply (around 40 %); a third one is China, the largest market for DHC today, but one on which renewable energy has yet to play a role at all. The chart shows the key factors impacting the potential of renewable DHC. The aim of the renewable energy roadmap (REmap) programme is to show a path towards doubling the share of renewables in the global energy mix by 2030.
