Power grids

[Translate to English:] © plainpicture/Peer Hanslik

The restructuring and expansion of the electricity infrastructure are a key challenge in the energy transition. Increased power generation from renewable sources such as wind and photovoltaics means that greater flexibility – in terms of both location and timing – must be built into the infrastructure. A needs-based expansion of power grids and storage facilities is required in order to ensure adequate north-south transmission of wind-generated electricity and to balance out fluctuations in power generation depending on wind conditions and time of day. s

Designing and managing flexibility in the power system, particularly in the electricity grids, is the focus of numerous studies conducted by the Oeko-Institut. Scenarios for flexible power generation and consumption have a particularly important role to play in identifying scope to ease the pressure on power grids and ensure cost-effective network development. Based on these scenarios, the researchers produce recommendations on the development of policy frameworks so that the power system can operate in a safe, economical and climate-neutral manner in future. This is the basis for optimising renewable energy use and reducing the costs of power generation.

  • The graphic compares transport companies’ expectations of the technical reliability of e-trucks with the experiences of e-truck pioneer companies. Among transport companies, around 9 percent expect e-trucks to be more reliable than diesel trucks, around 48 percent expect them to be equally reliable, and around 42 percent expect them to be less reliable. Among e-truck pioneer companies, by contrast, around 41 percent report that e-trucks are more reliable than diesel trucks, around 33 percent see them as equally reliable, and only around 16 percent rate them as less reliable.

    Electric trucks in the >16/18-tonne class have only been available as production models for a few years. Nevertheless, pioneering electric truck operators are already rating the reliability of these vehicles very highly – and generally consider them to be even more technically reliable than comparable diesel trucks. Transport companies with no relevant practical experience of electric trucks have a very different view of their reliability. Only a small minority expect electric trucks to be more reliable in day-to-day operation.
    These significant differences illustrate the ‘experience gap’ and the importance of knowledge transfer between pioneers and the wider industry in the current market phase for the successful market ramp-up of electric trucks.

  • The graphic shows assessments of the market relevance of alternative truck drivetrains and fuels for 2030. It compares the transport sector with e-truck pioneer companies. In the transport sector, the expected market relevance of e-trucks rises from around 1.6 to 2.0 points between 2021 and 2025. Hydrogen trucks, by contrast, are rated lower than in 2021. Biofuels, natural gas and e-fuels are rated lower or in the mid-range in 2025. Among e-truck pioneer companies, e-trucks are rated by far the most relevant option in 2024 and 2026, increasing from around 2.2 to 2.4 points. All other options — hydrogen, biofuels, natural gas and e-fuels — are rated significantly lower, mostly below 1 point.

    Hydrogen-based propulsion options are set to lose significant ground in terms of market significance by 2030. Whilst electricity-based fuels, biofuels and natural gas continue to be viewed as possible complementary options, their potential is considered to be significantly lower than that of battery-electric propulsion systems.
    In this general assessment, the sector as a whole and the pioneering companies with experience of electric trucks paint a very similar picture. It is striking, however, that companies already operating electric trucks view the market prospects for electric trucks with considerably greater optimism and regard the other alternatives with considerably greater pessimism than the sector as a whole. The positive experiences gained from real-world vehicle operation appear to be convincing. The high level of technical reliability, driver acceptance and the increasing suitability for regional and long-distance transport are giving the pioneering companies cause for confidence.
    At the same time, the continued market ramp-up remains closely linked to economic conditions, the expansion of the charging infrastructure and regulatory planning certainty.

  • Infographic from Öko-Institut e.V. titled "What does socially just climate protection mean?" showing strategies for sustainable, socially acceptable climate protection. Central box labeled "Socially Just Climate Protection" connects to three approaches:  Income support (short-term):  Includes transfer payments, climate dividends, and energy payments.  Price adjustments (short-term):  Includes CO₂ levy, reduction of renewable energy levy, and modernization levy.  Reduction in energy consumption and emissions (long-term and lasting):  Split into two areas:  Energy efficiency / renewable energies: building renovation, heating system replacement, climate-friendly mobility.  Behaviour / use: energy-saving advice and sufficiency.  Silhouettes of diverse people are shown at the bottom, representing the inclusive impact of these measures.

    What does socially just climate protection mean? Support for the transition to climate-friendly alternatives is the most important lever for shaping sustainable, socially acceptable climate protection.
