- The main goal of European Green Deal is for all EU member states to become climate-neutral by 2050. One option is CO2 sequestration. It means underground CO2 storage in geological structures. Theoretically, such sequestration could lower CO2 emissions by about 20%. This process has also, however, a number of disadvantages, such as high costs and restricted volume of appropriate geological objects. Sequestration processes can be divided into three groups: sequestration in depleted hydrocarbon deposits, sequestration in aquifers and sequestration coupled with EOR and geothermal energy capture. To sequestrate a significant part of emitted CO2, it is necessary to separate CO2 in power plants, to adapt appropriate geological objects, to investigate such objects and to build infrastructure and pipelines. What elements affect the cost of sequestration? First of all, separation of CO2 requiring large amount of energy (about 10% of energy produced in power plant). Next, gas must be compressed and rendered to supercritical/liquid phase. In the case of depleted hydrocarbon reservoirs, we know that the structure is tight and there is an infrastructure on the surface. When it comes to aquifers, it is necessary to carry out a full set of investigations, drill holes and build an infrastructure. If Poland wants to fulfill all tasks of Green Deal, huge investments are needed. The cost analysis should take into account such elements as the length of pipelines to be constructed and existing power grids. Any probable sequestration must be correlated with hydrogen projects. RES cannot work alone because they are not able to provide a constant supply of energy. It can be achieved with energy mix. Such a mix should be based on nuclear plants built in place of the greatest coal plants, which will make it possible to use the existing power grids. RES coupled with hydrogen economy should result in the second largest contribution to energy mix. All coal power plants must be modernized. Hybridization must be taken into account here (biomass or steam and gas power plants). This should reduce their emissions by about 30–40%. The share of sequestration will be very small and associated with geothermal energy.
