Aalborg CSP landed a new order to deliver an 8 MWth solar-thermal plant, which when completed will provide sustainable heating for 2,583 customers in the Copenhagen area. The solar field consisting of 11,312 m2 flat solar-thermal collectors will be the fifth green project that the company delivers in the country, thereby contributing to Denmark’s ambitious targets to become fossil fuel free by 2050.

Aalborg CSP received the order from the combined heat and power plant (Smørum Kraftvarmeværk A.m.b.A.) to deliver an 8 MWth solar heating plant that will reduce the facility’s natural gas dependency as well as stabilize energy prices. The 11,312 m2 solar field, which will be located in the town of Smørum, will consist of flat solar-thermal panels capable of producing 5,568 MWh heat annually. Aalborg CSP’s scope of supply also includes delivery of necessary technical installations and 2,2 km long piping for energy transmission.

 

Making renewable energy affordable

The solar heating plant is the fifth green project that the company builds in its home country that is known to be a pioneer in renewable energy solutions. Most recently, the company has completed a 16.6 MWth concentrated solar power (CSP) plant in Denmark. Currently the plant produces heat only, but when the second phase of the project (a biomass-Organic Rankine Cycle system) also goes online in 2018, it will be the first one in the world to demonstrate how CSP can optimize efficiency of ORC even in areas with less sunshine.

Rapid construction and installation

Shortly after signing the agreement with the Danish CHP plant, construction commenced in Smørum with expected handover taking place by the end of this year. Altogether 56 rows of flat panels will be installed with up to 20 collectors placed in one row. These 13,3 m2 optimized panels have shown the highest performance among all known mass-produced large-scale solar collectors on the international market. The same collector type was also used in another Danish district heating plant (Solrød Fjernvarme) where they performed beyond expectations during Spring and Summer of 2017.

The system is expected to harvest the first sunrays of 2018. Besides offering a cost competitive solution for heat production, the solar plant also avoids the emission of at least 1,100 tons of CO2 annually.

Aalborg CSP has commenced installation of a highly efficient solar district heating plant consisting of flat plate collectors in Denmark. After many successful CSP plants around the world, this will be the first stand-alone flat panel solar field that the company builds, and it will also be one of the most efficient ones in Denmark that is well-known for its green district heating facilities.

Aalborg CSP has investigated the potential to use solar heating to reduce the Danish district heating plant’s (Solrød Fjernvarme a.m.b.a.) natural gas dependency as well as to stabilize energy prices. To match the client’s energy requirements at the lowest possible cost, Aalborg CSP’s technology selection favored a 2,569 m2 flat panel system along with a 1,250 m3 heat storage accumulation tank providing 350 households with sustainable heating. The solar field delivered to Solrød Fjernvarme together with the accumulation tank will be able to cover 28% of the district heating plant’s energy demand and will keep energy prices stable.

The solar plant in Denmark will consist of 13 rows of GREENoneTEC collectors from the GK 3003 series with up to 20 collectors placed in one row. The 13,3 m2 optimized panels have shown the highest performance among all known mass-produced large-scale solar collectors on the international market. This enables the solar energy system in Denmark to become one of the most efficient flat panel fields in the country.

Construction of the plant was commenced in the middle of September and it is expected that the solar energy system together with the storage tank are installed in short five weeks. Besides offering a cost competitive solution for heat production, the solar plant also avoids the emission of at least 233 t/year of CO2.

The company’s first flat panel project was secured shortly after signing the distribution agreement with GREENoneTEC Solarindustrie Gmbh. The aim of this agreement has been to strengthen Aalborg CSP’s solar portfolio and to provide the district heating clients with more technology alternatives suitable to their individual energy needs. Aalborg CSP intends to implement combination plants utilizing the company’s core CSP technology with flat panels as well as conventional stand-alone flat panel systems.
