Green beginnings 2.0: Digitalized circularity for batteries

May 24, 2023

In our second webinar in the context of the Battery Regulation, we focused on digitalization and standardization for batteries, built a bridge between materials, production, use and recycling – and showcased the importance and added value of R&I in this process.

The Net-Zero Industry Act and the Critical Raw Materials Act have only recently highlighted the strategic relevance of batteries for Europe’s independence and competitiveness. Yet, they are the most complex elements in the system with tremendous environmental impact. Within the Circular Economy Action Plan, the Battery Regulation ensures sustainability, performance and labelling requirements, due diligence for social and environmental risks, waste collection, recycling efficiency, material recovery and replacement options. 

To implement the Battery Regulation, we need key enabling technologies and innovative solutions for greening the life cycle of batteries.

Our experts focused on the characteristics and requirements for a digital twin of sustainable cell production as well as the challenges and potential for implementing the Battery Passport.

We were delighted to get input from Anna Cavazzini (Member of the European Parliament) on the political debate about Digital Product Passports, the Battery Regulation and due diligence for social and environmental risks in global value chains.


The presentation and impulse paper will be uploaded soon.

In this much-anticipated edition of the Fraunhofer Twin Transition Series, we talked about challenges of and the potential for reusing, repairing and recycling. High-performance batteries are key for sustainable mobility, smart energy systems and Europe’s climate neutrality. Additionally, they are the most complex elements in the system with tremendous environmental impact. The European Union acts on this dichotomy with the upcoming Battery Regulation as part of the Circular Economy Action Plan.

Our Fraunhofer experts discussed the technological developments and solutions for the creation of a sustainable, resilient and competitive battery value chain. We deploy key enabling technologies for small-scale portable applications, mobility concepts or large-scale stationary systems and develop innovative solutions for manufacturing and the end-of-life phase. Our Patron, Malte Gallée, Member of the European Parliament and shadow rapporteur for the Battery Regulation, shed light on the political processes surrounding these endeavors.

The Photovoltaics Renaissance – New opportunities for a key enabler of the clean energy transition

March 9, 2021

Photovoltaics (PV) offer great opportunities to accomplish the goals of the European Green Deal but their full potential remains untapped to this day. The time has come for a Photovoltaics Renaissance: Europe is world leading in PV R&D, the cost of solar electricity has decreased significantly, and the number of installations is expected to increase sharply in the coming years. The market conditions offer great opportunities. However, there is a gap in Europe’s PV market due to the lack of production of PV within the EU.

Read about the latest scientific insights into potentials for PV in the EU in our impulse paper and the presentation of the 3rd Fraunhofer Green Deal Webinar.

Green hydrogen or green electricity for building heating?

July 22, 2020

In Germany and Europe, the energy policy discussion is currently strongly shaped by hydrogen as a universal energy source for the energy transition. However, the different sectors require a differentiated view and the question arises to what extent a new assessment of the fields of application must be made if compared to the power-to-gas approach (conversion from electricity to hydrogen to methane) with an overall efficiency of around 60%, whereas hydrogen has an overall efficiency of around 75%.

To find answers to those questions, the Fraunhofer Institute for Energy Economics and Energy System Technology IEE undertook a study and examined the use of hydrogen in the future energy system with a special focus on building heat supply and related it to the direct use of electric power in heat pumps.

In this Webinar, said study and its findings were presented to you by Jochen Bard (Fraunhofer IEE) and in conversation with Jorgo Chatzimarkakis (Hydrogen Europe) and Patrick Crombez (European Heat Pump Association) linked, amonst others, to the EU Strategy for Energy System Integration and the EU Hydrogen Strategy.
