IEA Study "Solar Heat Worldwide": Global Market Growth of 22 % in 2006

Submitted by Baerbel Epp on June 18, 2008

2006 was an extremely satisfying year for the global solar thermal industry. According to the new study “Solar Heat Worldwide. Markets and contribution to the Energy Supply 2006” on behalf of IEA Solar Heating & Cooling Programme the new installations grew 22 % in 2006. The authors from the Austrian research institute AEE Intec surveyed 48 countries and added up the newly installed collector area to 18.3 GWth (26.1 million m2).

Process Heat: the Solar Thermal Challenge of the Future

Submitted by Baerbel Epp on May 15, 2008

So far solar thermal technology is mostly used for domestic hot water, pool heating and room heating. It´s often forgotten that there is a huge demand for heat below 250 °C in industry, which can easily be reached with solar thermal collectors.

An international team of researchers working on behalf of the International Energy Agency estimated the realisable potential of solar process heat in the European Union at 100 GWth, which corresponds to 140 million m2 of collector area. T

Today, however, a solar thermal capacity of only 13.5 GWth is in operation across Europe. Task 33 of the International Energy Agency reported 85 solar process heat plants worldwide with a capacity of 27 MWth. However, this market segment seems to be waking up. Just recently, news about huge solar process heat installations did the rounds. There is the 13,000 m2 plant in Hangzhou, China, on the roof of the textile dyeing factory Daly Ltd., which is most probably the biggest installation for solar process heat in the world. The total investment adds up to RMB 12 million (€ 1.11 million) including the tanks and mounting system. According to the project developer, the Chinese company Shenzhen Quir Solar Technology Co., Ltd, the solar collectors will save RMB 3.38 million (€ 0.31 million) per year, so that the investment will pay off within 3 years. The hot water is provided at a low temperature of 55 °C. Secondly, this summer the German brewery Hofmühl GmbH in Eichstätt will start operating a pilot plant with 1,389 m2 of vacuum tube collectors, which will supply process heat between 90 and 140 °C to the brewing and cleaning processes. The owner of the system estimates a reduction of 20 % in the annual energy demand of the factory. The company is convinced that the investment will pay off and has plans for subsequent upsizing to 3,000 m2. The project is being subsidised by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety.

What are the main topics for the future to open this new market sector?

What are the advantages of solar thermal technology at a national level?

Submitted by Baerbel Epp on May 9, 2008

“Replacing imported fuels with local jobs”, this slogan of the European Solar Thermal Industry Federation (ESTIF) sums up perfectly the advantages of solar thermal technology for a national economy. The six biggest solar thermal markets in Europe – Germany, Austria, Italy, Spain, Greece and France – already exceeded 34,000 full time jobs in 2007 (check related article here). With an annual average growth rate of 20 % that is 6,800 jobs more each year. In the boom year 2008 in Europe this calculation results in 116,000 full-time jobs.

What are the long-term future perspectives of the sector in Europe?

Submitted by Baerbel Epp on May 9, 2008

The ambitious scenario of the European Solar Thermal Industry Federation (ESTIF) expects Europe will reach 0.7 kWth (1 m2 of collector area) per European in 2020, equivalent to a total capacity in operation in the EU by then of 320 GWth. To reach this target, a suitable support framework will be required and solar will then be widely used for both cooling and supplying process heat, though the majority of this capacity will still supply domestic hot water and space heating.

Which are the major solar thermal markets worldwide?

Submitted by Baerbel Epp on May 9, 2008

By far the largest solar thermal market in the world according to newly installed solar thermal capacity per year is China. In 2008, around 21 GWth (30 million m2) were sold in China, which was around 80 % of the world global solar thermal market.

Is solar thermal technology still a niche market?

Submitted by Baerbel Epp on May 9, 2008

There are a number of mature markets like Israel, Austria, Barbados, China or Cyprus where solar thermal is used by a wide majority of people for heating the domestic hot water and sometimes for room heating.
