Solar cooling demand on the rise in Italy, Spain and the Middle East

Submitted by Baerbel Epp on April 27, 2018
Photo: TVPSorption chillers may still be a niche market, but Europe’s manufacturers reported rising demand for solar thermal cooling in Italy, Spain and the Middle East in 2017. Solar thermal numbers are on the rise because of three factors: the potential to reduce power consumption, including peak loads; the option to use natural refrigerants, such as water; and the ability to provide demand-responsive heating and cooling throughout the year. The photo shows the solar-cooled headquarters of Agility, a logistics business based in Kuwait. The 234 m² of evacuated flat plate collectors which provide the building with energy can be seen behind it.

Solar showers for displaced people and refugees

Submitted by Baerbel Epp on April 20, 2018
Logo UNHCRThe UN Refugee Agency has begun ordering solar water heaters to improve the sanitary conditions in Ugandan refugee camps. The news ties in neatly with the first conference on Energy for Displaced People: A Global Plan of Action for Sustainable Energy Solutions in Situations of Displacement, an event which took place in mid-January in Berlin, Germany, and was attended by more than 100 delegates. The participants agreed to “lay the groundwork for the first-ever global, multi-stakeholder plan to ensure that crisis-affected people gain access to affordable, reliable, sustainable and modern energy services by 2030.”

New export-orientated collector and tank factory in Turkey

Submitted by Baerbel Epp on March 21, 2018
Bural Solar 1Collector and tank producer Bural Solar, founded in 2015, showed its product range at this year’s Mostra Convegno, an international trade fair in Milan, Italy, Mid March. The founder of the company, Hakan Alas, has been working in the solar thermal industry for 20 years. The export-focused business, based in Kayseri, central Turkey, started producing tanks and collectors in 2016. Mostra Convegno, which featured around 2,000 exhibitors, attracted more than 155,000 people, with every forth attendee coming from outside the country. It is 2018’s largest show about heating, ventilation, air conditioning and energy in Europe.

World’s largest flat plate collector manufacturers in 2017

Submitted by Baerbel Epp on March 19, 2018
The 2017 ranking of the world’s largest flat plate collector producers clearly shows the market dominance of Chinese companies. Even second-ranked Greenonetec, an Austrian collector manufacturer, is now majority-owned by the Chinese-based Haier Group. The corporation acquired 51 % of the manufacturer’s shares on 18 May 2017. The largest European flat plate collector producer was heating technology supplier Bosch Thermotechnik, although it remained at a certain distance from the top four. Business at Bosch Thermotechnik suffered from declining solar hot water markets in Germany (-16 %) and Brazil (-18 %). Nearly all the companies outside Germany increased production last year.

Thermosiphon market rebounds in Italy

Submitted by Baerbel Epp on February 16, 2018
Photo: Riccardo BattistiSystem suppliers and importers in Italy have reported significant growth in thermosiphon sales in 2017 thanks to the national support scheme Conto Termico 2.0. “Compared to the previous year, we more than doubled the number of thermosiphon units we sold in Italy in 2017, and most systems had a larger collector area because of the level of subsidies from Conto Termico 2.0,” said Export Sales Manager Andreas Andrianopoulos from Greek-based solar thermal manufacturer Cosmosolar.

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 plays minor role in Italy’s energy strategy

Submitted by Baerbel Epp on December 15, 2017
SEN LogoSolar thermal had been mentioned in only five lines in the first draft of Italy’s National Energy Strategy in June 2017, before public consultation took place. The aim of the document has been to set objectives and provide scenarios for national energy supply and demand until 2030. The country’s Ministry of Economic Development, which developed the Strategia Energetica Nazionale (SEN), received more than 1,000 comments in June and September 2017 and published its final version on 10 November 2017 (find both documents attached). Though the strategy paper contains promising renewable and energy efficiency targets, solar thermal – and heating and cooling in general – will continue to play second fiddle to natural gas.
 

Italy: Solar District Heating Shows Few Installations but Good Prospects

Submitted by Baerbel Epp on November 11, 2017
Ambiente ItaliaSubstantial solar resources and a generous incentive scheme called Conto Termico 2.0: Perfect conditions, it seems, for the widespread use of solar district heating. But barriers such as a low gas price and the concentration of district heating in a small part of Italy have so far limited deployment to a few installed systems. The map shows the three existing SDH plants in Varese, Sansicario and Lodi (red circles). A fourth with a gross area of about 600 m² is expected to come online in 2020 to feed heat into Turin’s district network operated by the Iren Group utility (yellow cirle).

Solar District Heating: How to Tackle Land Use Issues

Submitted by Baerbel Epp on October 11, 2017
SDH double useUsually, solar district heating (SDH) plants require large fields for collector installations, which has raised concerns at local level because of competing land uses and a system’s potential visual impact on the surroundings. One way out of this dilemma is to combine heat generation and fruit and vegetable harvest (see illustration). As part of SDHp2m…From Policy to Market, a Horizon 2020 project, some regions are looking to create regulations based on best practice examples of land use or spatial heat planning. This article will present showcases from the Styria region in Austria, Hamburg in Germany and Valle d’Aosta in Italy (see also the attached fact sheets).
