Solar 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.

Sonnenkraft, Holter and Tisun – the changing face of Austria’s industry

Submitted by Baerbel Epp on February 26, 2018
Photo: Thomas PirkerTwo strategic decisions taken by Austrian-based supplier Sonnenkraft in early 2018 have strengthened its position on the market. First, it secured an exclusive national distribution agreement with Holter, an Austrian wholesaler of heating equipment. Installers of Sonnenkraft equipment can now order products and systems on digital sales portal Holter online as opposed to getting them directly from the company. Second, on 4 December 2017, the supplier acquired the remaining 49 % stake in Austrian collector manufacturer Tisun, a competitor from which it had already purchased 51 % of the shares in May 2017. On 5 February 2018, the new owner asked for Tisun to be put into administration and an insolvency practitioner is now leading the restructuring effort.

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.

Three ways to read European market statistics

Submitted by Baerbel Epp on January 27, 2018
Solar Heat EuropeThere is more than one way to read 2016’s market statistics published by Solar Heat Europe about 2 months ago. One could emphasise the great achievements made in reducing emissions and creating jobs in the solar heating and cooling sector in Europe. One could likewise point to Denmark as a leader in solar district heating. A third possibility would be to concentrate on the continued decline in most key markets in Europe and the stark difference between renewable heating targets and their fulfilment in many countries. You can download the 5-page brochure here.

Solar thermal goes digital

Submitted by Baerbel Epp on January 3, 2018
WorkshopOn 14 December 2017, members of industry associations Austria Solar and BSW-Solar met founders of start-ups to draw up digital strategies for solar thermal. One of the key findings from the one-day workshop in Vienna, Austria, was that “traditional solar thermal companies cannot take on this task alone. They will have to partner with start-ups to explore and utilise the potential that digitalisation has for their business,” Roger Hackstock, Managing Director of Austria Solar, said.

French PVT market is picking up

Submitted by Baerbel Epp on December 22, 2017
DualsunThe IEA’s Solar Heating and Cooling Programme will create its own international research platform on PVT systems in January 2018. Researchers and industry representatives from 13 countries so far will then start evaluating new PVT systems for HVAC solutions. This IEA SHC task, which is planned to run until the end of 2020, is being announced at a time when the PVT market in several European countries, such as France and Switzerland, is picking up speed. Experts with an R&D or manufacturing background are welcome to join the platform (see the contact details at the end of this news article).

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.

IEA SHC Task 54: Solar Thermal Cost Reductions

Submitted by Baerbel Epp on November 26, 2017
Linz workshop Task 54The objective of IEA SHC Task 54 is to reduce the purchase price of solar thermal systems by up to 40 % across the entire value chain. To achieve this, the project partners have been evaluating technical and non-technical cost-saving potential, with low-cost materials, such as polymers, and production technologies bound to play an important role. At an early October workshop in Linz, Austria, about 50 project partners and guests discussed cost reductions made possible by new distribution channels, digital solutions and systems thinking approaches.

SHC 2017: Largest experts’ meeting on integrated solar heating and cooling

Submitted by Baerbel Epp on November 8, 2017
SHC2017_1500 experts from more than 50 countries attended the 5th International Conference on Solar Heating and Cooling (SHC) in Abu Dhabi, UAE, from 30 October to 2 November 2017. It was the first time that this biennial conference by the IEA’s Solar Heating and Cooling Programme had been organised jointly with the Solar World Congress by the International Solar Energy Society (ISES). The new partnership resulted in 2017’s largest experts’ meeting on integrated SHC solutions for buildings, industry, cities, regions and utilities, and in over 300 presentations.
