In this plenary, Alfred Spormann will present the issues of carbon capture and conversion into useful material or storage and he will address some of the challenges in implementing new technologies on a large scale.
The Novo Nordisk Foundation CO2 Research Center is a new, mission‐oriented Center with the purpose to develop novel science for CO2 capture and CO2 conversions for storage or utilization to replace fossil carbon and fossil fuel‐intensive processes with sustainable, CO2‐based technologies.
There will not be a single winning technology, and many different solutions are necessary. Therefore, the center pursues distinctively collaborative approaches between the chemical and life sciences. Integrated solutions are needed that make use of the best of the science and with a full, scalable technology platform in mind, to develop technical platforms that are tunable to local resources, regulatory settings, and expertise.
The research focus is on direct CO2 capture from air, microbial/chemical conversion of CO2 to C1-8 compounds, homogeneous, heterogeneous, and enzyme catalysis for CO2 capture and conversions, electrochemical reductions of CO2 and CO2-derived multi-carbon compounds and novel carbonate (bio)chemistries for CO2 capture and conversion.
The technical approach is be supported by advanced systems‐level modeling and simulations connecting scalable CO2 and carbon technologies with energy and other resource processes.

Chemical synthesis is responsible for significant emissions of carbon dioxide worldwide. These emissions arise not only due to the energy requirements of chemical synthesis, but since hydrocarbon feedstocks can be overoxidized or used as hydrogen sources. Using renewable electricity to drive chemical synthesis may provide a route to overcoming these challenges, enabling synthetic routes which operate at benign conditions and utilize sustainable inputs. We are developing an electrosynthetic toolkit in which distributed feedstocks, including carbon dioxide, dinitrogen, water, and renewable electricity, can be converted into diverse fuels, chemicals, and materials.
In this presentation, we will first share recent advances made in our laboratory on nitrogen fixation to synthesize ammonia at ambient conditions. Specifically, our lab has investigated a continuous lithium-mediated approach to ammonia synthesis and understood the reaction network that controls selectivity. We have developed non-aqueous gas-diffusion electrodes which lead to high rates of ammonia synthesis at ambient conditions. Then, we will discuss how water can be used as a sustainable oxygen-atom source and how carbon dioxide can be used to achieve carbon chain extension. These findings will be discussed in the context of a broader range of electrosynthetic transformations which could lead to local and on-demand production of critical chemicals and materials.

In 2015, the European countries signed the Paris agreement to keep the global temperature increase well below 2.0 °C. To do so, power-to-X technologies are needed to produce many of the valuable chemicals and fuels that we have obtained from fossil sources for generations. In this presentation, I will discuss how and when power-to-X fits into the green transition of Europe. How the need for power-2-X depends strongly on the level of climate ambition, and how we might create green bubbles where the technology can mature.

PtX opportunities and challenges for aviation and beyond
The European Union calls on its member states to reduce greenhouse gas (GHG) emissions by at least 55 % allready in eight years (2030), compared to 1990 levels. All sectors shall contribute to that collective pledge, while the GHG emissions in the transport sector have constantly grown in the last decades (despite a short-term Corona exception).
Sustainable fuels are seen as one part of the solution. PTX fuel based on renewable electricity, e.g. for upscale airline passengers, didn’t achieve great market success as a feel-good product until now. Techno economic and environmental assessment provides valueable information about the efforts (costs) and benfits (GHG abatement) of many decarbonisation measures.
Biological Methanation - An Industrial-Scale Application for Energy Storage, CO2 Reuse and Generation of Renewable Fuel
Electrochaea has developed a solution for energy storage, generation of renewable fuel, and carbon reuse. Our biological methanation process converts low-cost and stranded electricity and CO2 into renewable methane. The core of our power-to-gas system is a microorganism - archaea that excels through unprecedented catalytic ability and industrial robustness. The product gas “e-methane” can be stored directly into the existing infrastructure of the current gas grid without any further investments. Electrochaea’s “Power-to-Gas” technology is ready and available for a wide range of CO2 sources and can be built for applications from 10 MWe and to 100s of MWe.
How to get 10 times more sustainable liquid fuel out of green electricity than traditional P2X?
The talk will present an alternative approach to the production of sustainable fuels. Based on waste biomass, the so called HTL technology produces a biocrude that can be upgraded using green hydrogen to produce drop in fuels like diesel and kerosine. Circlia Nordic has made a number of innovations allowing 7x more fuel-energy produced than the invested process energy . After upgrading the energy yield on investment is still more than 10 times higher than traditional power2X technologies from CO2
From unrecycled waste to sustainable chemicals
Power-to-X technology offers a compelling and scalable opportunity to convert CO2 back into useful products and fuels. Production costs however remain high and significant new renewable power generation capacity is needed. By combining a Power-to-X solution with waste gasification technology however, carbon in unrecycled waste streams can be converted directly final product without the need for carbon capture and storage (CCS) technology. Further environmental benefits can be derived from replacing power currently generated by waste combustion with renewable alternatives.
CIP P2X projects – scoping and challenges
CIP is specialized in energy infrastructure investments and is among the largest funds globally within renewable. They are pioneers in taking global approach in realizing a profitable P2X plants for producing green hydrogen, ammonia, and methanol.
Synthesis gas, or syngas, is a key intermediate for nearly all carbon- and hydrogen-based chemistry. Today, syngas is primarily produced by steam reforming of hydrocarbons, a strongly endothermic process driven by the combustion of fossil fuels leading to excess CO2 emissions. eSMR™ is the electrified evolution of the world’s most common hydrogen-production method, steam-methane reforming. The eSMR™ approach allows for reducing the directly associated CO2 emissions from a syngas manufacturing plant by >95% compared to the fired reforming approach. Combined with a biogas feedstock eSMR™ facilitates a route to cost competitive green methanol.
The presentation will address the journey from REintegrate was established in 2018 until it was acquired by European Energy from 2022. Experience from the e-methanol value chain will be discussed including main business case drivers and possible end-uses of the e-methanol. Concrete end-use cases will be presented from the transport sector as well as the chemical industry. Future perspectives will be given in the last part of the talk.
Funded by EUDP, Haldor Topsoe, Vestas and Skovgaard Invest are project partners for the world’s first dynamic and flexible ammonia synthesis without a hydrogen storage. The green ammonia plant is powered directly by wind and solar power and is a behind-the-meter project.
Designed by Haldor Topsoe with a proven electrolysis technology, the flexible ammonia plant should demonstrate turn-down ratio of 5%-100% with ramp rates - dictated by the electrolysis technology - of 10 min. from min to maximum load. A hybrid power plant controller by Vestas must balance the power production from wind and solar power with the consumption of the ammonia plant and the power export to the grid. Power import is not allowed. The plant owner, Skovgaard Energy, will optimize the energy streams to maximize utilization of the wind and solar power production and to demonstrate PtX can provide power grid balancing services.
At GreenLab, we are developing the future of circular industrial symbiosis. Green hydrogen plays a vital role as an energy carrier and an intermediary in the industrials symbiosis' unique SymbiosisNet - an intelligent network of data and energy under development. GreenLab currently hosts five companies and two large ongoing PtX-projects with several industries involved. When finalised, the total hydrogen production capacity will be more than 100MW, and the park will have an 80MW direct connection to renewable energy sources from a local wind- and solar site. The presentation introduces the GreenLab concept and the PtX activities and related research in the park. The need for industrial symbiosis and the future role of hydrogen in our SymbiosisNet is highlighted.
