Large Scale Thermal Storage inspire the overall energy balancing

The large-scale solar heating plant in Braendestrup, Denmark, with a collector area of 8,000 m2 is enlarged to between 16,000 and 18,000 m2.

The plant will also get a seasonal storage, designed as a bore hole storage with 100 holes of 25 meters depth. The storage will also be utilized for storing overflow of wind power by applying a heat pump to transform the electrical power into heat. This is certainly not exergetically sound, but the alternative would be to stop the wind mills.

The renewable fraction will be 50% and the investment will be in the order of 3 mill. Euros. The plant will be designed by the German consultant company Solites, the Danish consultant company PlanEnergi and others. The project is supported by Energy Net Denmark.

Solar and Geothermal Power Production – An inspiration

Under the term GeoThermal the University of Adelaide, Australia, in cooperation with the company Permatherm, does investigating an very inspiring combination of solar thermal power production with geothermal energy. The goals for the project are: “This project aims to reduce the cost of solar thermal energy by 40 per cent through the integration of renewable energy technologies, while also achieving up to 50% renewable energy and true base-load capability…”.

Thanks for the inspiration. We ought to look at similar combinations for solar heating.

Energymap online

The Danish Industry is running a web system pointing at energy solutions, companies involved, projects, including solar thermal. You can find the map at http://www.energymap.dk. You find the Marstal Central Solar Heating Plant, their contact company and other information on the direct link http://www.energymap.dk/Profiles/Ramboll/Cases/Large-Scale-solar-heating-in-Marstal.

Any Danish owner of a plant or a company is invited to contribute to the common resource. Please do so.

Article on CSHP at Marstal

After a mail correspondence, John Perlin, did a great job on presenting the solar plant at Marstal. You may find the blog entry at http://www.miller-mccune.com/news/solar-water-heater-plant-denmark-1437 – Thank you John.

A new huge CSHP in Gram, Denmark

Gram Central Solar Heating

A new plant at Gram, Denmark, is to take the lead as the largest of it’s type. Based on all the experiences from the many installations, the first step of the Gram-plant is errected in marts-april 2009 (see picture – more pictures are presented in a Gallery).

The plant is described as follows:

Gram District Heating is expected to supply 17 procent the towns demand in district heating, which is approx. the total demand of 190 single family houses.

In a first fase, 802 solfangere from Arcon Solvarme are mounted in spring 2009. They produce approx. 7 MW yearly results in 4800 MWh and solar fraction of 117%. This leads to a CO2 emission reduction by 1,110 ton.

The expected life time for the installation is estimated to 25, whereas the oldest plant is still running at Saltum since 21 yeras.

The investement of 18 mio. Danish Kroner is expected to bring a pay back time of 7-9 years.

National development subsidies to CSHP in Dronninglund, Denmark

Through a research and development support of 11.9 mio. DDK, the Danish government pushes for CSHP with seasonal storage. In charge for the project is Planenergi, the most active consulting company in the business together with the plant owner, Dronningelund District Heating. The overall concept will be to use solar heating in combination with a large scale thermal storage and a heat pump. The collector area is planned to be approx. 35,000 square metres, a storage volume of 60,000 m³ and a heat pump with 3 MW effect.

The seasonal storage is planned as a pit water storage with floating lid, a well-known solution applied in the past.

The overall budget for the project is 80 mio. DDK or approx. 10.1 mio. Euros.

Online real time production data from Large Scale Solar Heating Plants

You are able to follow actual production data from large scale solar heating plants through at homepage. This gives you an idea of the performance for different plants at the same time, in real time . The texts are in Danish – however, the first value shows the actual production in kW, the second value shows the production per area and the third shows the actual solar irradiation.

Braendstrup large scale solar heating – co generation

The CSHP in Brandstrup is one of the very large plants at this time. The solar heating plant is connected to a co-generation plant, whereas other plants are connected to district heating plants with no production of electricity. Therefore the results of this plant is rather interesting to see.

The plant is presented at http://www.braedstrup-fjernvarme.dk/side1298.html (in Danish). The plant was taken into operation in 2007. It consists of 8,000 m² of solar panels. Guests are invited to visit the plant where a rest area is prepared to them.

3000 square meter solar plant in Hillerød

A new plant is placed north from Copenhagen in Hilleroed, more precise in Ulleroedbyen, a low energy building area. The plant is placed at the boundary of a motorway, not wasting too much agricultural land and acting as noise cover at the same time. The plant was raised in October 2007-2008.

The plant supplies a local district heating based on wood pallets for heating. The 240 panels of 12.58 m² are expected to produce a production of 37,500 MWh over the expected lifetime period of 25 years, saving the impact of 7,725 ton. CO

Solar heating at the motorway of Hillerød, Denmark

reduction through an investment of 6 mio. DDK, approx. 0.8 mio Euro.

Behind the Danish homepage http://www.solvarmecenter.dk, the consultant company PlanEnergi does present a large number of solar heating systems, large as small. The site is very beautiful and ought to get attention by the readers of this blog. Thanks to Jan Erik Nielsen from PlanEnergi Sealand. PS: Why do you not show actively, who’s behind this nice site?
