According to the company website, Singaporean investment holding company Rowsley had spent USD 5 million on the design of a selective coating for these metal plates. Professor He Tao from the China Academy of Building Research (middle of the photo), visited Sanqiaoneng’s coating plant in late January.

Crowdfunding the Heat Changers campaign

Submitted by Baerbel Epp on July 2, 2018
Photos: Heat ChangersThe German Solar Heating Initiative has put together a crowdfunding project to fund a consumer campaign called Heat Changers. Its initiators, Marisol Oropeza and Stefan Abrecht (first and second image from top left), have already brought some well-known supporters on board, including Markus Elsässer, Founder and Managing Director of Solar Promotion and organiser of the Intersolar Europe (bottom left), and Australian Ken Guthrie, formerly chair of the IEA Solar Heating and Cooling Programme (top right). The funding deadline for the EUR 35,000 project on kickstarter.com is 19 July 2018. The money is intended to be used for a six-month solar heat promotion campaign via social media, a website and other online tools.

Europe’s first-ever renewable heating and cooling target

Submitted by Baerbel Epp on June 26, 2018
Renewable Energy Directive for 2030After night-long negotiations, the European Parliament and Council have reached an agreement on the Renewable Energy Directive for 2030. At long last, discussions that started in November 2016 came to a close in the early morning of 14 June. The new regulatory framework stipulates that a 32 % renewable energy target is to be achieved by the EU in 2030. “This is a substantial increase compared to the 27 % originally proposed by the European Commission,” said Pedro Dias, Secretary General of Solar Heat Europe/ESTIF. “Moreover, the Commission can now take corrective action if this overall target is not met.”

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.

Green hotel in Italy’s mountains

The installation shown in the photo is proof that combining solar and other renewable technologies, such as biomass boilers and a solar-assisted heat pump, results in a synergy that can be very productive. The renewable heating system may have had a price tag of EUR 150,900 but uses innovative solutions, including phase change materials, to store thermal energy and saves EUR 16,000 per year.

A survey of the global market for concentrating collectors

Submitted by Baerbel Epp on June 1, 2018
Graphic: Solar PaybackConcentrating collector technologies are becoming an increasingly popular choice for customers requiring industrial heat or space heating. This year’s Renewables 2018 Global Status Report includes, for the first time, data regarding new installations of concentrating systems. Published at the beginning of June by the Paris-based REN21 network, it states that a minimum of 143 MWth was set up in 2017. The largest markets were Oman (100 MWth), China (15 MWth), Italy (14 MWth), India (2.8 MWth) and Mexico (2.8 MWth). The image shows the three technologies available for sale.

California Solar Initiative dominated by multi-family houses

Submitted by Baerbel Epp on May 25, 2018
Source: California Public Utilities CommissionIn 2017, the California Solar Initiative (CSI) – Thermal Program supported the installation of 20,000 m² of collector area, a 20 % increase over the prior year. With 10,832 m², or four times the area installed in 2016, multi-family buildings dominated the subsidy landscape for those 12 months. The surge was a result of a temporary increase in the incentive amount, from USD 29.85 per therm displaced to USD 70, granted across the service area of Southern California Gas Company. The chart, for which data has been supplied by the California Public Utilities Commission, shows the collector area subsidised and installed from 2010 to 2017.

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.

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.”

Heat pump makes use of low-temperature solar energy for space heating

Submitted by Baerbel Epp on March 29, 2018
Markus BeslmeislWith round about four decades in business, the German-Slovak Thermosolar Group is one of the oldest solar thermal manufacturers in Europe. It began producing collectors in 1972 in Slovakia and started offering a special evacuated flat plate collector in 1997. Last November, long-time sales manager Markus Beslmeisl (see photo) acquired the remaining shares in the company from Johann Kollmannsberger. Solarthermalworld.org spoke with the new managing director about Thermosolar’s special solar heat pump system, called Duo Premium.
