In Denmark , 30 percent of all energy consumed come from renewable sources , and the country intend to increase this percentage to 50 pct by 2030 with the long - terminal figure goal of becoming a low - emission country , sovereign of fossil fuel by 2050 . Denmark is far in the lead in the process of changing its heat and power production from coal - fired commingle warmth and force plants ( CHP ) to renewable energy such as wind , solar and geothermic , supplemented with CO2 achromatic bioenergy ( biomass , biofuel and biogas ) .
With 70 percentage of the renewable muscularity consumption in Denmark being bioenergy - based , this offers the opportunity to exchange the bioenergy from being CO2 electroneutral to being CO2 negative by apply C seizure and storage .
So far engineering science used for carbon seizure and warehousing has been right smart too expensive , and previous attempt at put through the technology at CHP plant have been desolate .
Now , a techno - economic study of the feasibility of a succeeding integrate CO2 neutral muscularity organisation , where the subsurface is employ for thermic energy supply and depot , as well as temporary CO2 storage is being performed as part of a research project carry out by Ramboll , GEUS , DTU and SINTEF . The study is support by the Danish energy technology ontogeny and demonstration research broadcast EUDP .

“ The survey looks very promising so far , and the technology used seems to be technically workable for major CHP plants based on biomass , and with heat convalescence for dominion warming , the economic feasibleness has ameliorate dramatically ” , order Ramboll engineer Thomas Paarup Pedersen , who is part of the core research squad .
The survey analyse a generic bio - plant life retrofitted with a CO2 capture . The generic bio - works is benchmarked against a computer address power plant , the biomass - fired Avedøre 1 CHP works , locate in the outskirts of Copenhagen . The plant has a capacity of 640 MWth , with net electric power output of 219 MWel and territorial dominion heating production of 352 MWth at full - load status . The plant operate with 100 % wood pellets . The Avedøre plant is look at representative of a state - of - the - art power industrial plant that has been converted from control with ember to biomass .
In the modelling work , the bio - plant is retrofitted with so - call Monoethanolamine ( MEA ) capture engineering , a well - known carbon capture proficiency of CO2 absorption by using amine . In the summons , steam from the CHP product is used to regenerate the aminoalkane used to capture CO2 . When leaving the gaining control plant , the CO2 is compressed to 110 saloon , carry by pipeline 3 kilometer towards northeast , and inject into a store reservoir in 1300 metres depth . 30 years injection of 1 million tonnes / year of CO2 is feasible from one injection well . The transport and injection case is based on capture from Nordjyllandsværket CHP flora after possible conversion to biomass - inflammation .
The research results so far show that it is possible to recoup a considerable amount of warmth from the CO2 gaining control cognitive operation to the DH system for function in the dominion heating system , significantly improving the thermic efficiency of the bio - plant and consequently keep down the price of CO2 capture by roughly 30 % , or from € 77 to € 52 per tonne of CO2 capture .
The final results of the enquiry project will be introduce at the TCCS-10 league in Trondheim in Norway on 17 - 10 December 2024 .
