Comparative study on the Sectoral implementation of European Green Deal in different types of Energy Models

The European Union's Power sector and the end-use sector are responsible for nearly 75% of the EU's Greenhouse Gas emissions. It is the need of the hour to decarbonise the EU's energy system to achieve climate neutrality by the mid-century. The European Green deal lays down very ambitious targets of 55% emission reduction in 2030 and 100% emission reduction in 2050 from 1990 levels. Increased penetration of renewable energy technologies in the Power sector and simultaneous electrification of the end-use sector to meet the increased supply of electricity from renewable energy will accelerate the decarbonisation process. Therefore, this thesis aims to analyse the impact of the European green deal targets in transforming the power sector into a carbon-neutral power sector. This is done by conducting a comparative analysis of various energy system models which were modelled based on European Green Deal targets. Emphasis is placed on understanding the constraints and assumptions in running the energy system models. The results showed that achieving carbon neutrality by mid-century is considered possible while overachieving the Green Deal targets for 2030 and 2050. The use of carbon capture technologies in decarbonising the power sector is only in sequestrating residual emissions or when the carbon price is increasing exponentially. Increased carbon tax, Sector coupling and society's attitude toward reducing carbon emissions play a crucial role in achieving this ambitious goal.
