Sustainable Energy Production
Our mission is to provide the required energy on a fully renewable basis by advancing the fundamental and technological principles that underpin next-generation energy systems. We integrate computational modeling, advanced separation technologies, thermochemical energy storage, catalyst design, and fluidized bed conversion to enable efficient production, transformation, and utilization of renewable energy carriers. From green hydrogen and biomethane to sustainable aviation fuels and syngas-derived products, our research spans the entire value chain—from material and reactor development to pilot-scale demonstration. Through rigorous experimentation, high-fidelity simulations, and process optimization, we develop scalable solutions that replace fossil resources with renewable feedstocks and energy inputs, thereby enabling a resilient and low-carbon energy future.

| Abstract | Biorefinery technologies focus on converting biomass into valuable products such as food and feed products, biofuels, biochemicals, and biomaterials in a sustainable, integrated and efficient way. We follow cascaded separation concepts to maximise the valorisation of the bioresources. Thus, we consider green chemical engineering principles e.g. by applying green solvents in extractions, by integrating membrane separations where feasible, and by circulating auxiliary materials, solvents and catalysts. Novel biorefinery concepts require experiments at lab scale and pilot scale as well as suitable analytical procedures. Our activities include the utilisation of lignocellulosic biomass and forestry by-products, sugar and starch biorefineries as well as wet, green biomass and CO2. |

| Abstract | Computational Fluid Dynamics (CFD) offers powerful insights into complex reactive flow systems, helping to improve energy efficiency and reduce emissions. In this project, CFD is applied to model thermochemical conversion processes such as combustion, gasification, and pyrolysis. By coupling chemical kinetics with heat and mass transfer, we explore how process conditions influence reaction pathways and product yields. Advanced numerical simulations allow us to predict performance under realistic industrial conditions and to evaluate new reactor concepts before physical testing. The results contribute to the design of cleaner, safer, and more efficient energy and chemical production systems, supporting the transition toward sustainable technologies. |

| Abstract | Transforming captured CO2 into valuable resources is an important task within current efforts to transition into a green economy. Efficient catalysts are needed to facilitate CO2 as a feedstock for highly demanded chemical building blocks (olefins, hydrocarbons), and to lower energetic costs. Tandem catalysts are promising candidates: Two catalysts with different functions are combined into one solid to couple two processes: i) CO2 to methanol, and ii) methanol into desired products. The research focuses on the design of catalysts and understanding of the interplay between both catalyst components. |

| Abstract | Dielectrophoresis (DEP) is investigated as a separation technology for recycling waste from electrical and electronic equipment (WEEE). DEP enables particle separation based on size, shape, and material properties and is well established in microfluidic systems. Recent work demonstrates that DEP filtration can be scaled to high-throughput operation and applied to lithium-ion battery (LIB) waste streams. However, the governing mechanisms of DEP filtration under industrially relevant conditions are not yet fully understood. This project combines experimental studies with CFD simulations to analyse DEP-driven particle transport at high throughput and to characterise the polarisation behaviour of particles typical of LIB waste. The results support the development of a DEP-based unit operation that can be integrated into existing WEEE recycling processes to improve material recovery and reduce chemical consumption. |

| Abstract | Induction heating offers a precise and energy-efficient method for activating catalysts directly at their active sites. This project explores the design and optimization of catalytic systems that can be selectively heated using electromagnetic fields. By controlling temperature at the nanoscale, we aim to enhance reaction rates, reduce energy losses, and enable faster process start-up and shut-down. The combination of advanced materials engineering, process modeling, and experimental validation paves the way for next-generation catalytic processes that are both efficient and adaptable to renewable energy inputs. |

| Abstract | Process intensification refers to strategies and technologies aimed at making chemical and industrial processes more efficient, compact, and sustainable. By integrating innovative methods such as advanced contactor and flow designs, multifunctional equipment combining reactions, separations and heat transfer, as well as intensified mass and heat transfer techniques, process intensification enhances energy efficiency, reduces waste, and minimises environmental impact. Techniques like microcontactors, reactive distillation, high gravity extraction and membrane processes help optimise operations, leading to lower costs and improved product yields. With our novel extraction, adsorption, membrane and electrochemical separation techniques we target to integrate process intensification concepts into green chemical engineering, green pharma, and biorefineries, carbon capture and hydrogen. |

| Abstract | Process simulation provides a virtual laboratory for analyzing and optimizing chemical and biotechnological processes. We combine simulation with life cycle assessment (LCA) to evaluate both technical performance and environmental impact. Using state-of-the-art modeling tools, we explore energy and material balances, heat integration strategies, and emission profiles. By linking process models with laboratory and real-world data, we can identify efficiency improvements and design more sustainable process configurations. The integration of LCA ensures that innovations are assessed holistically—from raw materials to end-of-life—enabling informed decision-making for sustainable technology development. |

| Abstract | Our research with respect to sustainable fuels focuses on the production of energy carriers with minimal environmental impact. We investigate thermochemical pathways such as dual fluidized bed (DFB) gasification at pilot scale (100 kW) for converting renewable feedstocks into syngas. This syngas is suitable for subsequent production of sustainable fuels like synthetic natural gas (SNG), high-purity hydrogen or Fischer-Tropsch products (e.g. sustainable aviation fuel=SAF). The research group’s technical lab is based on modelling, experimental investigation and advanced meassurement methods. The experimental results are analyzed with process modelling enabling system integration with increased energetic efficiency. Our goal is to create scalable sustainable fuel production technologies that support the transition to a climate-neutral energy system. |
