WG 5 – Connecting mobility and energy networks, sector integration

The Working Group 5 “Connecting Mobility and Energy Networks, Sector Integration” examines which infrastructure for alternative drive infrastructure is needed to achieve Germany’s climate targets in the transport sector by 2030 and which measures should be taken for further development. Topics here include: charging and tank infrastructure for electromobility, Power-to-X (hydrogen and e-fuels) and LNG in the areas of passenger cars and commercial vehicles. In addition, the working groups will discuss prerequisites and data requirements for intelligent grid integration of electromobility and aspects of sector integration.

Reports of Working Group 5 “Connecting mobility and energy networks, sector integration” (in german language)

Netzintegration von Elektromobilität – Basis für eine Erfolgreiche Sektorkopplung. Eine Definition

Successful grid integration is a key element of the future uptake of electromobility and of sector integration. In its report “Grid integration of electromobility – basis for successful sector integration – a definition”, WG 5 develops a definition of grid integration which all stakeholders can agree to and which establishes common ground in the market.

Kundenfreundliches Laden – Fokus Öffentliche Ladeinfrastruktur

Charging an electric vehicle is a new experience for users, which differs from refuelling a conventional car. In its paper “Customer-friendly charging – Focus on public charging infrastructure”, WG 5 outlines for the first time a set of common definitions and gives recommendations to market participants and industry organisations to make charging a pleasant experience for users. These recommendations for action refer to the five characteristics of customer-friendly charging: a) simple, b) widely available, c) transparent and d) secure. The additional, less central feature of “convenient charging” comes with further recommendations.

Bedarfsgerechte und wirtschaftliche öffentliche Ladeinfrastruktur – Plädoyer für ein Dynamisches NPM-Modell

With its report “Needs-based and economical public charging infrastructure”, WG 5 takes the initial concept for the identification of the charging infrastructure required for electromobility further, using various scenarios. The calculations take into account energy and output needs, efficiencies as well as the interaction between charging and output variations. In view of the call for a flexible approach in the “Charging Infrastructure Master Plan”, the model enables a dynamic expansion of the charging infrastructure.

LNG- und CNG-Strategie im Schwerlastverkehr

Compared to Diesel, LNG (Liquefied Natural Gas) and CNG (Compressed Natural Gas) have the potential to reduce CO2 by about 22 percent. With natural gas, sulphur and nitrogen oxide emissions can be reduced to almost zero, particulate matter by about 95 percent and noise by about 50 percent. LNG and CNG are currently the only immediately available and competitive alternatives to Diesel in heavy goods vehicles. An increase in vehicle demand is key for an expansion of the filling station infrastructure because a speedy market penetration supports its economical operation.

Roadmap PtX

Power-to-X-technologies in transport really come into their own when long ranges or heavy loads are required. Apart from long-distance rail and road transport, shipping and aviation could be potential markets. PtX technologies can make a significant contribution towards climate protection. In order for this to happen, one of the key elements is to successfully establish electrolysis for the production of green hydrogen. Investment in the development of electrolysis plants and notably current electricity generation costs are barriers which need to be overcome if the hydrogen generated in this way is to be competitive.

Red-Flag-Bericht 10% EV-Neuzulassungen

In its “Red flag report 10% electric vehicle registration”, WG 5 seeks to answer the question of action required in technical, organisational and regulatory terms, in order to be prepared for a situation in which 10% of newly registered vehicles are electric in the near future. Even a dynamic increase in electric vehicles was found not to lead to shortages in the generation of renewable forms of energy. In cases of concentrated increases in major conurbations, local bottlenecks in the electrical grid are possible which need to be looked at on a case-by-case basis and resolved through intelligent load management. Responses are needed in both the public and the private charging infrastructure.

Sofortpaket Ladeinfrastruktur 2019

In its paper „Sofortpaket Ladeinfrastruktur 2019“, experts of WG 5 check which barriers need to be dismantled in order to speed up the expansion of the charging infrastructure, to be able to charge at home, at work or at public charging stations, should there be an increase in the number of electric vehicle registrations. Recommendations are made in particular with regard to amendments to tenancy and property ownership legislation, a support programme for private charging infrastructure as well as an improved overall availability and simplification of the approval process for public infrastructure.
