Such use may also be an option for Amager Bakke in the future. Use of the captured CO 2 to produce, for example, chemicals and fuels such as methanol and DME would naturally increase the overall climate gain further, provided there is access to green electricity. Those analyses also included the recycling of the captured CO 2, which currently only takes place at three incineration plants in the world, two in the Netherlands and one in Japan. In the past, Valentina Bisinella has conducted life cycle analyses of incineration plants across Europe, leading to the same overall conclusions. "Even when factoring in the CO 2 emissions that may occur both during transport and storage in the subsoil, carbon capture clearly results in net climate benefits," says Valentina Bisinella. These activities may cause unintentional emissions of the greenhouse gas into the atmosphere, while sea transport also causes CO 2 emissions. The other drawbacks for the climate highlighted by the analysis are primarily associated with the transport and storage of the captured CO 2 in the subsoil. Transport and storage may result in emissions The overall net energy efficiency is thus not affected, but there is a shift from less electricity to more heat," explains Assistant Professor Valentina Bisinella, DTU Environment, who carried out the analysis. For some incineration plants, this would have a considerable impact on their overall CO 2 accounts, but at Amager Bakke, the steam from the carbon capture in fact increases the heat output utilized in the district heating system by 20 per cent. However, electricity production is reduced by approx. "Carbon capture reduces CO 2 emissions from the incineration plant. The analysis looked at a number of waste composition scenarios. The focus of the life cycle assessment has been to investigate the impact of the carbon capture plant on the energy generated by the incineration plant as well as other environmental impacts. During incineration, CO 2 is released from the waste, which includes food waste and textiles. The energy generated is used to produce electricity and heat. The assessment has made it possible to examine the advantages and disadvantages of the carbon capture plant from the point of view of the climate impact.Īmager Bakke incineration plant burns, among other things, household waste that has not been sorted for recycling. Not just from the pilot plant currently installed by DTU, but from a plant that would cover the entire Amager Bakke facility. DTU Environment has therefore conducted a life cycle analysis, which has systematically assessed the impact from a possible carbon capture plant installed at the Amager Bakke incineration plant in Copenhagen. However, like all other technologies, carbon capture leaves its own imprint on the outside world. 1 day ago &0183 &32 Carbon-capture technologies are designed to capture emissions, or 'flue gas,' from the smokestacks of power plants and manufacturing facilities.
