German climate neutrality pathway outlined in Ariadne report, revealing cost-efficient strategies by 2045
In a significant development, a comprehensive report titled the Ariadne Scenario has been released, outlining a cost-efficient pathway towards a climate-neutral future for Germany. The report, which was created with the involvement of prominent scientists from various research groups, offers insights into the energy transition and its potential to modernise the economy.
The costs of climate protection, as outlined in the report, are strongly influenced by the development of energy demand. The development of a European hydrogen network is identified as crucial, and the additional cost of the transformation is projected to be limited to an average of 16 to 26 billion euros per year until 2045.
The report highlights the significant role of renewable energy sources in the electricity mix. By 2035, the share of wind and solar energy is expected to rise to 84 to 91 percent. This shift offers Germany the opportunity to take a leading role in the export of green technologies.
The accelerated switch to electric mobility is also cost-efficient and presents an industrial policy opportunity. By 2030, battery-electric passenger cars and trucks in Germany are projected to have a market volume of 80 billion euros per year. If it is possible to reduce energy demand through climate-friendly consumer behavior and switch to climate protection technologies more quickly, energy cost savings could even exceed climate protection costs.
The report also emphasizes the importance of the European coordination of energy and climate policy in minimizing costs. Institutions involved in the report include the Potsdam Institute for Climate Impact Research, Technical University of Berlin, Fraunhofer Institute for Systems and Innovation Research, Fraunhofer Institute for Solar Energy Systems, Fraunhofer Institute for Energy Economics and Energy System Technology, and Eidgenössische Technische Hochschule Zürich.
In the building sector, the heat transition accounts for a large portion of investment needs. Heat pumps, which can usually provide space heating more cost-effectively over the entire lifecycle than fossil heating systems, are identified as a key technology.
The wholesale electricity price is projected to stabilize at a long-term average of 70 to 80 euros per megawatt hour. Various sectors, such as electric cars, heat pumps, electrolyzers, battery and heat storage, wind turbines, and control units for smart integration and flexibility, offer large potential for growth.
The Ariadne Scenario Explorer provides the latest results of the Ariadne scenario analysis online, offering flexibly adaptable graphs and tables for public access. Furthermore, various Ariadne webinars discuss scenarios and pathways for designing the energy transition cost-efficiently.
By 2030, an electric vehicle is expected to be cheaper than a combustion engine for almost all end-users due to lower energy and maintenance costs. The energy transition offers Germany the opportunity to modernize its economy and outlines a pathway to a climate-neutral future with prosperity.
Notably, the new federal government aims to achieve climate neutrality by 2045. If Germany continues to rely on fossil energy carriers, it may miss its climate goals and lose its competitiveness. Therefore, the Ariadne Scenario report serves as a valuable guide for policymakers and industry leaders as they navigate the energy transition.
