By Jens Rasmussen, Technical Manager, isoplus Denmark EXPORTING THE RIGHT SUPPLY OF HEAT AND KNOWLEDGE
CASE
In the years ahead, district heating will generally play an increasingly major role in Europe, as no less than 40% of the energy consumption is used for heating homes. Using district heating as an energy source permits significant reductions in the carbon account, allowing us to conserve and protect our environment now, tomorrow and in the future.
In Kohtla, Estonia, isoplus Denmark has supplied pipes for establishing a new district heating supply between the towns of Järve, Ahtme and Sompa. By the end of 2012, a total of 34 km of pre-insulated pipes will connect these three picturesque towns with district heating. All towns used to have district heating, but the existing heating works are due to be shut down. Instead, the region’s refinery, owned by VKG Soojus AS, will supply the towns with environmentally friendly surplus heat. This is one of the few places in the world where they refine ‘shale oil’, extracted by pyrolysis of sedimentary rock containing kerogen, which can be transformed into petroleum-like fluids.
KNOW-HOW RELATING TO PRE-INSULATED DISTRICT HEATING PIPES
In Denmark, approximately 40% of the district heating production is based on non-fossil fuels, thus being CO2 neutral. This means that we are well positioned to help other countries meet their targets for reducing their CO2 emissions. VKG Soojus AS had no previous experience of installing transmission pipelines of the order of magnitude in question, and isoplus has therefore been involved as a close partner throughout the entire process.
THE NEW DISTRICT HEATING NETWORK S EASY ON THE ENVIRONMENT
The environment in Kohtla will in future be spared a good deal of CO2 emissions, due to utilisation of the surplus heat from the refinery, so that the need to use other fuels will be reduced, including those of fossil origin, which would otherwise have been used to fuel the district heating system.
