Summary: This study conducts a comparative techno-economic analysis of adding CO2 capture technologies to existing oil shale power plants in Estonia. The results show that oxy-fuel combustion capture performs better than post-combustion capture, but it leads to a reduction in power plant efficiency. The feasibility of CO2 capture in Estonian oil shale power plants depends on long-term trends in the electricity market and CO2 emissions trading system, and it may require state aid, which could reduce the overall competitiveness of the Estonian economy.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
