Oliver Hennes, M.Sc.
has been working at EWI since 2016, first as a Research Analyst and now since 2018 as a Research Consultant. In consulting projects for clients from the industry and public sectors, he has examined, e.g., the efficient use of electricity in heat and mobility sectors. He has advised, among others, the German Federal Ministry for Economic Affairs and Energy (BMWi), the Ministry of Economic Affairs, Innovation, Digitalization and Energy (MWIDE) of the state of North Rhine-Westphalia and the German Energy Agency (dena). His research focus lies in the field of electricity market modelling, market integration of renewable energy and sector coupling. Before joining EWI, Oliver Hennes studied Economics at the University of Cologne and absolved an apprenticeship as an industrial clerk for SolarWorld AG.

Effects of CO2 prices on the building, transport and energy sectors
In a new short study, the EWI examined the real impact of CO2 prices on private households and the overall energy system. The analysis was carried out jointly with the Institute for Future Energy Consumer Needs and Behavior (FCN) of RWTH Aachen University on behalf of E.ON SE. The FCN estimated investment and consumption decisions of private households in the transport and building sector on the basis of empirical models. On this basis, the EWI derived feedback effects of these decisions in the energy system. Thus, the effects of a CO2 price were consistently mapped in the overall system.

dena-Leitstudie Integrierte Energiewende (dena Study on Integrated Energy Transition)
The dena-Leitstudie Integrierte Energiewende develops and compares transformation pathes for the energy system in Germany with the objective to attain the climate-political goals by 2050. It pursues an innovative cross-sector scenario approach. At the same time, it is based on the branch knowledge of more than 60 partners from all relevant sectors and on the continuuos exchange with important actors from politics, society and science. The objective is to give impulses for designing the energy system by 2050. ewi ER&S is the main scientific advisor to the study. The central results of the study say that Germany will be able to attain its goals to reduce greenhouse gas emissions by 80 as well as by 95 % up to the year 2050 if the strains in all sectors are increased. Therefore, the roll-out and system integration of renewable energy sources must be forced, the end energy consumption has to be reduced by extensive energy efficiency efforts, and synthetic regenerative energy sources must be used on a big scale. A broad mix of technologies and energy sources makes the transformation of the energy system more cost-efficient than a fortified use of electricity-based applications.

Cost-efficient realization of sector coupling
The study examines options for a medium-term and long-term attainment of German goals for the reduction of greenhouse gases by 2050. The focus lies on finding cost-optimal development pathes in the energy consumption sectors of buildings, transportation, industry and in the energy sector. The study finds that a technology-open approach is to be preferred to an extensive electrification of the consumption sectors. In addition, the German climate goals are classified into the European context, incentive structures are analyzed from stakeholders’ pespectives, and recommendations for a further development of legal frame conditions are yielded. The study was commissioned by the Ministry of Economy, Innovation, Digitalization and Energy of the state of North Rhine-Westphalia (MWIDE). The ef.Ruhr GmbH is the cooperation partner for examining the implications on the electricity networks.

Gebäudestudie – Szenarien für eine marktwirtschaftliche Klima- und Ressourcenschutzpolitik 2050 im Gebäudesektor
The Buildings Study (Gebäudestudie), initiated by the members of the Allianz für Gebäude-Energie-Effizienz (geea), provides an economic analysis of the buildings sector. It investigates how the transformation of the buildings sector can be accomplished by an interplay of building shell, installation technology and a changed energy production, to reach an attainment of reducing greenhouse gases by 80% and by 95%. The study was created in the context of the dena-Leitstudie Integrierte Energiewende (Integrated Energy Transition). ewi ER&S is the main economic reviewer of the study, cooperating with FIW and ITG as technological reviewers.
