Lithuania: Can Solar Thermal Beat Low Biomass Heat Prices?

Submitted by Baerbel Epp on August 14, 2017
Lithuania District HeatingWith biomass prices on the rise, solar district heating could become profitable in Lithuania. But without investment grants, payback periods were still too long, it said in the conclusion of a 2015 SDH market study by LEI, the Lithuanian Energy Institute (see the attached document in Lithuanian). The photo shows the country’s first SDH system set up in 2011. Installed on the roof of the boiler house, it preheats water for a wood chip boiler in the district heating station of Dūkštas, a town in eastern Lithuania. The demonstration unit with 82 m² of vacuum tube collectors received funding from international organisations.

Denmark: Abundant Biomass, Little Solar in Industry Incentive Scheme

Submitted by Baerbel Epp on April 2, 2015
Danish incentive programme RE for Production Processes has been extended by another year until 2021. In 2014, in its first full year, the scheme supported 196 renewable projects, of which only one included solar heat. Since the programme began in August 2013, it has funded all together ten solar energy projects, which each year produce around 13.4 MWh combined. Among them are nine PV projects and only one solar thermal installation. More information about the solar process heat project could not be obtained, as it has not been finished yet. The statistics were provided by the Danish Energy Agency (DEA), the programme’s administrator. 

Denmark: Combined CSP and Flat Plate Collector System Supplies Solar District Heating

Submitted by Baerbel Epp on January 30, 2015
Solar District Heating Tars7 January 2015 was the starting date for the construction of a unique solar heat plant for district heating in the Danish village of Tårs, 30 km north of Aalborg. It combines parabolic trough collectors and flat plate collectors in order to cover 30 % of the heat demand by the village’s district heating network, without the need for seasonal storage. The system is expected to come into operation during the second quarter of 2015.

Denmark: Launch of Subsidy Scheme for the Industrial Sector

Submitted by Baerbel Epp on September 26, 2013

Denmark can now look at the “sunny” side of things: Mostly associated with wind, the Scandinavian country has recently had a remarkable record when it comes to solar thermal energy, which is widely used for district heating. In March 2012, the Danish parliament set the ambitious target of a 35% share of renewable energies in the country’s energy consumption by 2020.

Denmark: Solar District Heating Capacity increases 5-fold

Submitted by Baerbel Epp on October 2, 2011

 Existing and planned solar district heating systems in Denmark Solar heat is penetrating Denmark’s district heating networks at an unprecedented rate: Around 90,000m2 of collector area (63 MWth) are going to be connected to the country’s networks in 2011. The map shows the existing and planned solar district heating systems in Denmark, including the installed or planned collector area. The Danish consulting and engineering company PlanEnergi was responsible of drafting the map in the framework of Task 45 “Large Solar Heating/Cooling Systems, Seasonal Storage, Heat Pumps”. The task was started in January 2011 by the International Energy Agency’s Solar Heating and Cooling Programme (IEA SHC), which will run until December 2013.

Large Solar Thermal Systems: Development and Perspectives (2008)

Submitted by Raquel Ponte Costa on February 23, 2010

Currently there are around 120 large scale solar heating plants with more than 500 m2 of solar collectors in operation in Europe, 10 of which are located in Denmark.

The first Danish plant was built in 1987 with 1,000 m2 of ground mounted collectors. Today it still remains active, producing heating for the citizens. The Danish government has set very high targets for district heating in the upcoming years. In the “Strategy for solar thermal”, the Danish Energy Agency has set an ambitious target of 10% of district heating load to be covered by solar thermal in 2030.
