<h1>Danske Regioner Klima09UK Page 14</h1>solar heatIng All in all, these factors have turned solar thermal collectors into a realistic alternative to conventional district heating, both in Dronninglund and probably everywhere else. the Citizens demand it Dronninglund's CHP (central heating plant) station was completed in 1990, but the heating plant's first boiler station was built in 1959. The plant supplies heating to the 1,350 households of the town of Dronninglund. The heat is currently based on natural gas, of which around three million cubic metres are used every year: "When the district heating plant was finished in 1990 it looked new and smart, but the technology, on which it built, was a hundred years old. The heat was produced by burning fossile fuel, in our case natural gas. This was modern at the time, but even back then we already knew that natural gas is a scarce resource which we only have for a limited time, until it is all used up. Therefore, as board-members we had to look to the future and search out the next source of heat," says Carsten Møller Nielsen. Solar thermal collection emerged as the technology the board was most interested in. Over the following years the members sought expertise and experience with this technology. They visited the Saltum district heating plant in North Jutland, which was working on a model for a solar thermal plant. Furthermroe, the board also visited similar plants in Austria, the Netherlands and Germany, but without finding the optimal model: "The plants we were introduced to turned out to be either too small, too unprofitable, or too unreliable to work with. We had continually kept the general assembly informed, that we were looking at solar thermal collectors. Then suddenly, after a few years the request came back the other way: "Now it's time you did something about finding an alternative source of energy." The general assembly literally obliged us to identify a valid alternative. And from then on there was no going back. We knew we had to find an alternative. We also knew that the solution must not cost the citizens more than they currently paid for heating. Also, we knew that we had their full support. The last factor, in particular, is what has enabled us to get this far," says Carsten Møller Nielsen. "Many challenges still lie ahead to be tackled before the final project can take shape. I am quite sure of that, because nobody else has ever tried to do what we are doing, on this scale. As such, it is essential that the consumers support us, and are fully informed about the project and what it involves. This in turn requires a very high level of information, so that people actually do understand the project and gain confidence in it." saves moRe than 6,000 tons of Co2 annually Dronninglund is not the only place demonstrating increased climate awareness; consumers in general tend to demand cleaner energy. Hence, other similar companies are also considering solar thermal collectors. As a result, solar thermal collection technology has reached the stage at which its stability, sophistication and price are now at a level which permits the building of a solar thermal plant on the scale planned by Dronninglund District Heating. And we are talking big installations and comprehensive figures. Dronninglund District Heating will cut the first sod for the project in spring 2010. This should be taken quite literally: fifteen metres down, and covering an area of 10,000 square metres, roughly equivalating the size of two football pitches. Subsequently, the hole will be filled with between 60,000 and 70,000 cubic metres of water. It will in fact be the biggest lake in the area and the world's largest solar thermal plant. The cost of the entire installation will be around EUR 11.7 million. "We could actually supply the entire town with heating in the very same way. The technology is already there and available to us. But this would imply a doubling of the investment and a interest level which I would not like to commit us to pay. The planned size of the installation is still very big, and serves to demonstrate that this can be done on a large scale," says Carsten Møller Nielsen. The installation will be operational in 20102011, and 2011-2012 will be the first season in which the sun exclusively will be ensuring hot water in Dronninglund. Chemical engineer Ole-Kenneth Nielsen of Denmark's National Environmental Research Institute has calculated how much CO2 the current Dronninglund district heating plant would emit if it were to produce those 20,000 MW hours of energy that the solar thermal collector plant is expected to supply every year. Currently, Dronninglund District Heating uses three million cubic metres of natural gas a year; on the basis of standard values for heating value and emission factors, this would produce 6,744 tons of CO2-emissions. In future, the environment will be spared this. the regional growth forum sets the ball rolling W hen, a few years ago, the general assembly of Dronninglund District Heating first demanded that CO2-friendly ideas be translated into action, the company initially applied to the North Jutland Growth Forum for funding for a preliminary survey and calculations. Per Alex Sørensen, who has been a close partner of the solar thermal collection project via the engineering company PlanEnergi, states that the funding obtained from the North Jutland Growth Forum was what initially made it possible to examine the potential of the project and its future prospects: "We didn't know much about the market potential of solar thermal collectors, and we were in doubt about whether the plant could be made to function without public subsidies. We needed to investigate this thoroughly, and the grant we received made this possible," he says. In later phases of the solar thermal collector project, Dronninglund District Heating has received a total of EUR 1.75 million from EUDP, the Danish Energy Authority's Energy Technology Development and Demonstration Programme. Per Alex Sørensen is looking forward to see the project in full size, producing district heating for the town. "It represents a possible way out of the fix we will otherwise be in when the natural gas runs out," he says.
