Thermal Desalination Driven by an Innovative Salinity Gradient Solar Pond Located in the Coastal Waters of Open Seas (2015)

Submitted by Francesco Gattiglio on April 10, 2015

This presentation, prepared by Dr. Ir. Ing. Dick G. Klaren of Klaren International, proposes the use of a salinity gradient solar pond (SGSP) in coastal waters as renewable energy source for thermal desalination. The document was presented at the CWC Technical Seminars featured at the Saudi Water & Power Forum (SWPF), held between 12 and 14 January in Riyadh, in the Kingdom of Saudi Arabia.

Denmark: Abundant Biomass, Little Solar in Industry Incentive Scheme

Submitted by Baerbel Epp on April 2, 2015
Danish incentive programme RE for Production Processes has been extended by another year until 2021. In 2014, in its first full year, the scheme supported 196 renewable projects, of which only one included solar heat. Since the programme began in August 2013, it has funded all together ten solar energy projects, which each year produce around 13.4 MWh combined. Among them are nine PV projects and only one solar thermal installation. More information about the solar process heat project could not be obtained, as it has not been finished yet. The statistics were provided by the Danish Energy Agency (DEA), the programme’s administrator. 
 

Solar thermal polygeneration system for cooling, fresh water and domestic hot water supply: Experimental analysis (2014)

Submitted by Francesco Gattiglio on April 1, 2015

In this paper, presented at the World Renewable Energy Congress of London of 3-8 August 2014, a solar-thermal poly-generation system for chilled water for air conditioning using absorption chiller, pure water with membrane distiller and domestic hot water by heat recovery is presented. 

Germany: Polymer Collector Design for EUR 25 Production

Submitted by Baerbel Epp on March 31, 2015
Polymer CollectorsDuring project ExKoll, scientists at the Fraunhofer Institute for Solar Energy Systems, Fraunhofer ISE, have developed a new low-cost design for solar thermal collectors. The entire production of an 80 cm x 160 cm collector made of polypropylene (PP, drawing on the right) with an operating temperature resistance of up to 100 °C would amount to a mere EUR 25. A design which includes an absorber made of polyphenylene sulfide (PPS, left drawing) and which can resist operation temperatures of up to 250 °C would have production costs of around EUR 45 per panel. The following text was based on a presentation held at a workshop of Task 39, Polymeric Materials for Solar Thermal Applications, in Israel in April 2014. ExKoll ended in December 2014, Task 39 of the IEA’s Solar Heating and Cooling Programme did so in October 2014. A new task, which will have the focus on cost reduction potential in collector production and will be led by Michael Köhl from Fraunhofer ISE, is scheduled for the second half of 2015.

KiotoManagers from four different companies showcasing one innovation – a rare occurrence, even at a large fair like the ISH 2015 in Frankfurt. At the beginning of March, Rudolf Pfeil, CEO of Resol, Christian Beckmann, Sales Manager Key Account and OEM at Wilo, Günter Kohlmaier, CEO of Kioto Solar, and Karsten Pillukeit, CEO of Esbe Group (from left), jointly presented the newly developed fresh water module, Fresh Hydro, at the booth of Kioto Solar. Thanks to a patented temperature control, the fresh water module offers rapid response times without over- or undershooting. The developers have promised a comfortable showering experience at 40 to 160 litres per minute and a temperature of 45 °C. The fresh water system was one of a number of solar thermal innovations at the ISH which were worth taking a closer look.

China: Sunrain to Solve Pengpusang’s Financial Troubles

Submitted by Baerbel Epp on March 29, 2015
PengpusangChinese flat plate collector manufacturer Pengpusang (international brand Prosunpro) from Shenzhen in southern China seems to have overcome its financial difficulties: “We continue to produce absorbers and collectors and have six colleagues in the overseas sales team,” Alon Ryan confirmed at the end of February. The Vice Director-Overseas of the Marketing Department emphasised that there was “no stop in production, and we are still supplying all our important customers.” The photo shows the anodisation of absorber fins on the factory line in Shenzhen.

“Germany is one of the most challenging markets”

Submitted by Baerbel Epp on March 28, 2015
Albert LooschenThe Chinese Haier Group is a fairly young company, which has grown into a huge and still rapidly expanding corporation. Founded in 1984, Haier currently has 70,000 employees and achieved a turnover of USD 29.5 billion in 2013. For five years now, the group has headed the ranking of the largest household suppliers worldwide. In 2007, it started to manufacture solar collectors at its Chinese headquarters in Qingdao, Shandong Province, and has since offered solar thermal systems on the national, as well as the international market. The man who started the sale and distribution of Haier’s solar thermal products in Germany in 2011 was Albert Looschen. Since that time the energy consultant has managed the solar thermal activities of Haier Deutschland, and solarthermalworld.org spoke with him at the ISH fair in Frankfurt in March. Prior to Haier, Looschen had been working as an independent energy consultant for seven years. 
 

Germany: 174 Solar Process Heat Applications in 2.5 Years

Submitted by Baerbel Epp on March 27, 2015
Process heat pieOver the last two and a half years, the German Market Rebate Programme for Renewable Energies, MAP, has been subsidising half of the net costs associated with solar process heat for industrial and commercial use in Germany. All in all, the administrator of the programme, the Federal Office for Economic Affairs and Export Control, BAFA, has received applications for 174 systems, of which 88 have so far been set up by the applicant and subsidised by the programme. “The programme started off well, but now the number of applications is stagnating,” Ralph Baller, Head of the MAP division, says. The University of Kassel’s additional publicity measures, which address planners and installers alike, are hoped to increase the popularity of the subsidy scheme again. The pie chart shows the customer groups of solar process heat among the 174 applications which have been submitted since the programme was launched in August 2012.
