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.

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.

Austria: New Medium-Temperature Collectors Show Remarkable Yield in District Heating Use

Submitted by Baerbel Epp on March 2, 2017
Graz Test Field SOLIDDuring the last seven years, a group of scientists has monitored selected large solar thermal installations in Austria on behalf of the Austrian Climate and Energy Fund. The gathered data confirms that these plants have been reliable and produce satisfactory yields. Particularly the new generation of large-scale medium-temperature collectors either with a foil or with a second glass cover shows remarkable results in district heating use. The 2,490 m² solar field (see photo) which has fed heat into the district heating network of Graz, Austria, reached a yield of 489 kWh/m².

Switzerland: Borehole Storage Regeneration as Solar Thermal’s Ray of Hope

Submitted by Baerbel Epp on December 22, 2016
Solarwärme SchweizOn 24 November, the fifth Solar Heat Switzerland (Solarwärme Schweiz) conference organised by the solar industry association Swissolar, the building services association suissetec and the Federal Office of Energy was held in Lucerne, Switzerland. As 2017 funding for solar heat incentives remains in doubt in several cantons and the priorities of the country´s energy policy haven’t been announced yet, the market outlook for solar thermal has not been very encouraging. But there seems to be a ray of hope in the form of low-temperature collectors for borehole regeneration and solar district heating.

Germany: “Performance-based incentives for all solar thermal plants”

Submitted by Baerbel Epp on November 11, 2016
In spring 2015, Germany´s Federal Office for Economic Affairs and Export Control (BAFA) introduced a performance-based incentive for solar heating as an alternative to the scheme offering incentives based on collector area. Recently published statistics have shown the new programme to grant higher financial support for about one-third of the currently funded projects. The others still receive funding from the previously established scheme. 
 

Solar District Heating: Good Performances All Over Europe

Submitted by Baerbel Epp on October 4, 2016
Crailsheim Monitoring ResultsThe 4th International Solar District Heating (SDH) Conference, which had been organised under the auspices of Horizon 2020 project SDHp2m…from Policy to Market on 21/22 September 2016 in Denmark, showed the importance of analysing real-life monitoring data from European SDH plants, with one conference session (Advanced SDH systems II) dedicated exclusively to the topic. These kinds of comparisons enable an understanding of the actual performance of such large collector fields and offer an opportunity for optimising power output and for creating best-practice examples of new plants. For example, the chart displays ten years’ worth of monitoring data from the German plant in Crailsheim, which has met solar yield expectations.

Denmark: Solar Concentrating Systems to Offer Wide Array of Uses

Submitted by Baerbel Epp on June 20, 2016
Aalborg Tars InaugurationAt present, the Danish turnkey supplier of concentrating solar systems, Aalborg CSP, has two more large projects under construction. Both installations – one for Danish district heating company Brønderslev Forsyning and one for Australian vegetables producer Sundrop Farms – cover electricity and heat demand at their sites. Yet another first-of-its-kind project was inaugurated in August 2015 in the Danish village of Tårs (see photo), 30 km north of Aalborg. It entailed 4,039 m² of parabolic trough collectors and a preheating flat plate collector field of 5,972 m². Simulations have pointed to a 31 % coverage of annual heat demand even without seasonal storage, since overheating in summer can be avoided by moving the parabolic trough collectors out of focus. Aalborg CSP is an experienced planner of steam and boiler systems and has been offering concentrating solar solutions since 2007.

Austria: Decision on Operating Company for Big Solar Graz Expected Soon

Submitted by Baerbel Epp on June 17, 2016
Gleisdorf Solar 2016“Large-scale solar thermal systems in the GW range – an insignificant niche market or the future for solar thermal?” was the official title of a panel discussion at the Gleisdorf Solar conference in Austria in early May. The most important question was: What will be next for the planned 350 MWth solar district heating system called Big Solar in the Austrian city of Graz? “The challenge was to adapt the Danish district heating solutions to Austrian conditions,” emphasised the project’s initiator, Christian Holter (right), Managing Director of S.O.L.I.D. Meanwhile, Christian Stadler (left), Managing Director of one of Arcon-Sunmark’s subsidiaries, Arcon-Sunmark Germany & Austria, represented the company that has stated his own interest in realising Big Solar.

Italy: First-Year District Heating Yield Better than Expected

Submitted by Baerbel Epp on May 20, 2016
Output VareseThe first and so far unique solar district heating plant in Italy completed its first year in operation in mid-May this year. According to metering by the operator of the 990 m² collector field, utility Varese Risorse, output was significantly higher than expected. The chart shows the total output measured over almost 12 months: It was 13 % higher than the target figure. The solar district heating plant was developed and installed by a newly founded Italian company, SDH Energy, which also guaranteed the solar yield (red line).

Austria: Low Oil Price and Lack of Political Support Weakens Market

Submitted by Baerbel Epp on February 15, 2016
Heating with oilAccording to the ISOL Index by solrico and market data from the industry association Austria Solar, the solar thermal industry is heading into another year of declining markets. Low oil prices and corresponding campaigns of the fossil heating industry have had a substantial impact on this renewable technology. The banner shows the slogan “Heizen mit Öl – das zahlt sich aus” (The Benefits of Using Oil to Heat Your Home) on the website of the Austrian mineral oil industry, which offers grants of EUR 2,500 for the installation of a condensing oil boiler in a single-family building. Austria Solar has also criticised the reduction in the renewable budget of the Austrian Climate and Energy Fund as well as the complicated incentive scheme rules throughout the states. The large-scale project market is what keeps the industry alive.
