REN 21: Solar Thermal Contributes Significantly to Hot Water Production

Submitted by Baerbel Epp on June 30, 2014
top ten 2012According to REN21’s Renewables 2014 Global Status Report, which was published at the UN-hosted Sustainable Energy for All Forum in New York at the beginning of June, solar thermal technologies contribute significantly to hot water production in many countries and increasingly to space heating and cooling, as well as industrial processes. REN21 is a global multi-stakeholder network for renewable energy policy, connecting key actors from governments, international organisations, industry associations, science and academia, as well as civil society. First released in 2005, the report provides a comprehensive and timely overview of renewable energy markets, industries, investments and policy developments worldwide. The renewable energy data is provided by an international network of more than 500 contributors, researchers and authors. According to report data, the world added 55.4 GWth (more than 79 million m2) of solar heat capacity in 2012, increasing the cumulative installed capacity of all collector types in operation by over 14 % for a year-end total of 283.4 GWth. The chart above shows the shares in global capacity in operation across 2012’s top ten countries.

Experimental Analysis on Performance of Solar Cooling System in UAE conditions (2014)

Submitted by Chris Heron on June 4, 2014

This presentation on the experimental analysis on the performance of a solar cooling system in United Arab Emirates’ (UAE) conditions was given by CSEM UAE Innovation Center at the second Southern African Solar Energy Conference (SASEC) that took place on 28 January 2014.

India: First Stakeholder Workshop for Solar Thermal Roadmap

Submitted by Baerbel Epp on May 17, 2014
Greentech RoadmapWhereas India shows enormous demand for thermal energy in the industry and for cooking, solar thermal has so far only covered 0.2 % of the total heating and cooling need. Therefore it is urgent to scale up the use of decentralised solar thermal technologies. Supported by the Shakti Foundation, consultancy Greentech Knowledge Solutions (GKSPL), located in New Delhi, will prepare a roadmap for scaling up deployment of decentralised solar thermal technologies in India. With plans to publish the roadmap by October 2014, GKSPL organised the first stakeholder workshop in Pune at the end of April, gathering around 40 experts mainly from the solar thermal manufacturing business.

Technologies and Perspectives of Solar Cooling Systems (2014)

Submitted by Chris Heron on May 14, 2014

This presentation, given by Dr. Uli Jakob of Solem Consulting, at the AHK (German-Australian Chamber of Industry and Commerce) conference in Sydney in March 2014, gives an update on the technologies and perspectives of solar cooling systems.  It covers the different technologies used, such as sorption chillers, integrated hydraulic units and standardized solar cooling kits.  It also provides a short overview of solar collector technologies for solar cooling.

International Energy Agency : Solar Heating and Cooling Programme (2013)

Submitted by Chris Heron on May 8, 2014

During the annual Research Review of the Australian PV Institutes (APVI), held in November 2013, Ken Guthrie, Deputy Chair of the IEA SHC Executive Committee, gave a presentation on the Solar Heating and Cooling Programme of the IEA.

Developing the Australian Solar Cooling Market: Status Update and Lessons from the Solar Thermal Industry (2013)

Submitted by Chris Heron on April 25, 2014

This report on the development of the solar cooling market, from Jeremy Osborne of Solem Consulting, was presented at the Australian Solar Cooling Conference in Sydney in 2013.

It first provides an overview of the overall Australian solar thermal market and then focuses in particular on solar cooling industry and how it can learn from the solar thermal industry in order to grow its market.

Germany: Additional Support for Small Solar Cooling Systems

Submitted by Baerbel Epp on February 3, 2014
Since January 2014, companies have been able to receive grants for their thermal-driven sorption cooling systems with a cooling power between 5 kW and 500 kW from the programme for commercial cooling technology in Germany. Until 2013, the minimum cooling power for the programme had been 50 kW. The Federal Environment Ministry published the amendment on 16 December 2013 (see the attached document). The programme supports solar thermal cooling, but also cooling systems driven by other green heat sources, such as industrial waste heat, cogeneration plants and district heating. The subsidy is 25% of the net investment for the cooling system, including installation and consulting costs.

Austria: Large-Scale Solar Plants Subsidy Scheme Shows Increase in Average System Sizes

Submitted by Baerbel Epp on January 3, 2014
2013 was already the fourth year for the Austrian Climate and Energy Fund’s subsidy scheme for large-scale solar systems.The demand for it was also still great: All in all, 37 projects profited from a total subsidy amount of about EUR 4.5 million (see the attached document). 18 of these projects were accompanied by case studies. The programme subsidises large-scale solar plants across the following application areas: solar process heat (6 systems), solar feed-ins into heat networks (11 systems), high solar coverage (15 systems), solar-supported air conditioning in combination with warm water and heating (4 systems), as well as new technologies and innovative approaches (1 system). The pie chart shows the shares of the aforementioned applications in the total subsidised collector area.
