eMethane is more than a renewable substitute for fossil gas. It is a strategic pathway for linking captured CO2 and green hydrogen into a storable, transportable energy carrier that strengthens European energy resilience while opening new carbon value chains. This session will explore how CO2-to-methane – at the same time – can support a more robust, resilient and circular energy system, reduce dependence on fossil carbon, and act as a bridge between carbon capture and downstream carbon-based products. Moving further, the key question is how new methanation routes can improve efficiency, expand the relevance of different CO2 sources like atmospheric and oceanic CO2, and create value beyond combustion alone.
Questions to be addressed:
Is the current geopolitical state a driver for eMethane – or the green transition as a whole – or should we rather invest in bringing European fossil infrastructure online again?
How can eMethane contribute to energy resilience in a carbon-constrained future?
Which CO2 sources are most relevant for next-generation methanation?
How do new CO2-to-methane routes compare in efficiency and system value?
Can methane also serve as a platform for higher-value carbon products?
Moderator: Anne Mette Frey, Section Manager, Danish Technological Institute

Electrochemical energy conversion technologies are central to the green transition, spanning applications from hydrogen production to energy storage and carbon utilization. Despite targeting different applications, the technologies share common foundations in electrochemical interfaces, materials, and stack engineering. This session brings together three perspectives: catalyst development for electrochemical CO₂ reduction, novel redox-active molecules for flow batteries, and novel stack designs for PEM electrolysers. While PEM/AWE electrolysis represents a relatively mature technology, CO₂ electrolysis and next-generation flow batteries are still evolving. The aim of the session is to explore if insights and technical solutions within electrolysers, flow-batteries and CO2 reduction can be used across the domains.
Questions to be addressed:
Can (PEM) electrolyser stack concepts be transferred to redox flow batteries and CO2 electrolysers?
What limits durability and lifetime across these technologies?
How do materials choices impact cost and scalability? What is the impact of electrolyte pH on material choices/opportunities?
Opportunities for cross-learning between the domains?

Decarbonising polymers is one of the major unresolved challenges in the transition away from fossil carbon. This session will explore how captured CO2 can become a sustainable carbon source for polymer value chains, helping close the loop in plastics and reduce dependence on virgin fossil feedstocks. A central theme is industrial realism: not only developing new materials but enabling drop-in fossil-free routes to key platform chemicals and polymer building blocks that fit existing applications, standards and production systems. For scientists and industry professionals alike, this session addresses a critical question for the future of sustainable materials: how to combine circularity, performance, and scalability in one of the world’s most important carbon-based industries.
Questions to be addressed:
Should sustainable polymer strategies focus on new materials or fossil-free versions of existing ones?
Which CO2-derived platform chemicals are most relevant for industry?
Why is recycling alone not enough to close the plastics carbon loop?
How can CO2-to-polymers combine circularity with industrial implementation?
