Due to the increasing European import dependency, significant additional natural gas volumes will be required. In addition to the Nord Stream pipeline, the Nabucco and South Stream pipeline are projects planned for the next decade to provide further gas supplies to the European market. As one of...

Europe's increasing import dependency in natural gas facilitates a number of new infrastructure projects. However, up to now it has always been difficult to assess the full impact of these projects as interdependencies within the whole European gas infrastructure system were hard to predict. We...

To achieve the EU's new climate target of reducing emissions by at least 55% until 2030, the European Commission proposed a reform of the EU ETS in its 'Fit for 55' legislative package. The reform entails an increase of the linear reduction factor (LRF), an adjustment of the intake rules for the...

Hydrogen is viewed as a promising supplement in future energy systems with high penetration rates of renewable energy (RE) generation. As conversion technology between the two secondary energy carriers, hydrogen and electricity, particularly grid-connected electrolysers, have a role to play....

We perform a model-based analysis of the impact of a renewable hydrogen quota on EU gas and electricity markets. By comparing a scenario in which a renewable hydrogen quota with tradable certificates is imposed on final gas consumption in the sectors of the economy outside the EU ETS with a...

By 2050, the European Union aims to reduce greenhouse gases by more than 80 %. The EU member states have therefore declared to strongly increase the share of renewable energy sources (RES-E) in the next decades. Given a large deployment of wind and solar capacities, there are two major impacts...

In Europe, the availability of renewable energies, especially from sun and wind, differs significantly across regions. Consequently, cooperation in the deployment of renewable energy among European countries potentially yields substantial efficiency gains. However, in order to achieve the 2020...

A linear energy system model is presented which optimises the future development of electricity generation capacities and their dispatch in Europe. Besides conventional power plants, combined heat and power plants and power storages, the model considers technologies that support the future high...

In this paper, the implications of alternative decarbonization pathways for Europe's power sector up until the year 2050 are analyzed. In specific, an electricity system optimization model is used to investigate the minimal costs of decarbonization under a stand-alone CO2 reduction target and to...

As an attempt to fi ght global warming, many countries try to reduce CO2 emissions in the power sector by significantly increasing the proportion of renewable energies (RES-E). A highly intermeshed electricity transmission grid allows the achievement of this target cost-efficiently by enabling...
