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...

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 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...

Recently, several articles rely on marginal abatement cost (MAC) curves to analyze the EU ETS. While the assumptions on MAC curves drive the results, the prevailing literature on the EU ETS does not take the shape of MAC curves into account. This paper discusses the implications of MAC curve...

The paper at hand examines the power system costs when a coal tax or a fixed bonus for renewables is combined with CO2 emissions trading. It explicitly accounts for the interaction between the power and the gas market and identifies three cost effects: First, a tax and a subsidy both cause...

Despite regulation efforts, CO2 emissions from European road transport have continued to rise. Increased use of electricity offers a promising decarbonization option, both to fuel electric vehicles and run power-to-x systems producing synthetic fuels. To understand the economic implications of...

This paper numerically analyzes redistribution effects resulting from cooperation among European countries in achieving the 2020 targets for electricity generation from renewable energy sources (RES-E). The quantification of redistribution effects builds on the theoretical analysis by Unteutsch...

It has been shown that international cooperation in achieving renewable energy targets, e.g., via a common tradable green certificate market, increases overall welfare. However, cooperation in the support of electricity from renewable energy sources also leads to regional price effects, from...

Liberalization of network industries frequently separates the network from the other parts of the industry. This is important in particular for the electricity industry where private firms invest into generation facilities, while network investments usually are controlled by regulators. We...
