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.

Global electricity demand for air conditioning to triple by 2050

Submitted by Baerbel Epp on June 28, 2018
“Growing demand for air conditioners is one of the most critical blind spots in today’s energy debate,” Fatih Birol, Executive Director of the IEA, said as he presented the findings of The Future of Cooling report in May. The chart shows that, in the baseline scenario, cooling is projected to be responsible for between 25 % and nearly 50 % of peak electricity loads in the United States, the Middle East, Indonesia, India and Brazil in 2050. Globally, demand is expected to triple by the same year. The world’s stock of AC units is said to rise to 5.6 billion by 2050, up from 1.6 billion today, which reportedly means an average of 10 ACs will be sold each second over the next 30 years.

Daniel Mugnier Is New IEA SHC Chairman

Submitted by Baerbel Epp on June 27, 2018
The new chair of the IEA Solar Heating and Cooling Programme, also known as IEA SHC, will be Daniel Mugnier, a leading expert in solar cooling. Mugnier, who heads the R&D department at French-based Tecsol, was elected during an executive committee meeting in Stockholm on 21 June and will hold the position for two years. He will replace Australian Ken Guthrie, who has chaired IEA SHC since 2014.

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.”

SDH prefeasibility studies in Bosnia and Croatia

Submitted by Baerbel Epp on May 29, 2018
Source: CoolHeatingIn early 2016, EU-funded CoolHeating began using the know-how acquired during best practice projects in Austria, Denmark and Germany to help with the implementation of small modular renewable heating and cooling grids in southeastern Europe. In mid-March, the CoolHeating partners published seven prefeasibility studies of district heating and cooling across five municipalities in Bosnia and Herzegovina, Croatia, Macedonia, Serbia and Slovenia. Because of geographical features, most projects favoured biomass, but solar thermal does play a crucial role in the proposals created for the Bosnian town of Visoko (see map) and the Croatian city of Ozalj.

Solar steam for process heat and air conditioning

Submitted by Baerbel Epp on May 18, 2018
Photo: Industrial SolarGerman Fresnel collector manufacturer Industrial Solar has completed its second industrial solar heat installation in Jordan. Three years after it had put into operation a Fresnel field at pharmaceuticals company Ram Pharma, a 700 kW concentrating collector system came online at tobacco manufacturer Japan Tobacco International, also known as JTI, in late 2017. The solar steam that the new system produces is used in two ways. It is injected into the steam grid to supply process heat to manufacturing and it powers a new installed double-effect absorption chiller to provide on-site buildings with air conditioning. JTI regards the solar steam unit as a strategic investment to demonstrate its commitment to establishing sustainable supply chains and, especially, to reducing the carbon footprint of its global operations.

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.

German associations partner up to promote sustainable cooling

Submitted by Baerbel Epp on April 27, 2018
Logos solar coolingIn early 2018, two German organisations agreed on a joint membership model to promote solar thermal air conditioning and cooling, a niche market in the country. The cooperation between the Green Chiller Association for Sorption Cooling and the Central Association for Refrigeration, Air Conditioning and Heat Pumps, or ZVKKW for short, is hoped to popularise innovative and sustainable cooling solutions. According to a survey among members of the Green Chiller Association, some companies have shifted away from solar-powered sorption cooling because they consider systems combining solar PV and split air conditioning units to have greater economic benefits, especially if the cooling season is short. Others are increasingly using waste heat to run sorption chillers. 

First cooling installation on Indian government building

The installation offers a capacity of 150 tons of refrigeration (528 kW) to cool the Gandhinagar Thermal Power Station’s office building in Gujarat state in western India. The total investment, including the collector field, mounting equipment, chiller and hot water storage tanks, amounted to Indian Rupee (INR) 52 million, or around EUR 0.7 million, which corresponds to specific costs of 1,327 EUR/kW.

Financial support for concentrating solar systems extended until 2020

Submitted by Baerbel Epp on March 14, 2018
Photo: HoneywellThe “order” published by the Indian Ministry of New and Renewable Energy on 26 February 2018 put an end to the uncertainty which had pervaded the industry. In the 2-page document, the ministry pledged to continue its investment subsidy programme for concentrating solar thermal systems. The target until March 2020 is 90,000 m² of collector area. The financial year 2017 to 2018, during which 20,000 m² were planned to be subsidised, is almost over.
