In this episode of Innovate and React, I welcome my former PhD mentor, Dr. Thomas Seidensticker from TU Dortmund, to explore how oleochemistry can provide a sustainable, locally grown alternative to crude oil for the chemical industry. While the traditional chemical sector relies heavily on cheap fossil fuels, plant oils naturally offer closely related hydrocarbon chains that can be functionalized for everyday products like surfactants, cosmetics, and polymers. However, shifting away from crude oil presents the unique challenge of dealing with complex, inhomogeneous fatty acid profiles that constantly vary by plant origin and season. We discuss the strategic importance of feedstock sovereignty and how diverting plant oils from low-value biodiesel combustion into long-lasting chemical products can create vital carbon sinks to help meet future renewable carbon targets.
How do you transform these varied plant oils into the standardized building blocks the conventional industry demands? Thomas explains the breakthrough potential of utilizing the unsaturated carbon-carbon double bonds in plant oils, highlighting technologies like cross-metathesis and his own university spinoff, Simplyfined. We also dive into the historical 1938 roots of homogeneous catalysis, the logistical hurdles of scaling pilot volumes, and why agile startups are essential for taking the disruptive technological risks that large, slow-moving chemical corporations currently avoid.

In this episode of Innovate and React, I welcome Dr. Ronja Rappold, co-founder of TENO Bioworks, to explore how microorganisms and synthetic biology can transform alternative carbon sources into high-value chemicals. While biological manufacturing is well known for producing life-saving pharmaceuticals like insulin or traditional fermented goods, shifting base and fine chemical production away from fossil fuels presents a unique challenge. Relying solely on agricultural sugars introduces significant “food vs. fuel” conflicts and risks breaching critical planetary boundaries, including land use, freshwater consumption, and nutrient cycles. Ronja and her team address this by targeting C1 feedstocks—specifically green methanol derived from captured CO₂.
How do you teach an industrial workhorse to live on a completely foreign feedstock? Ronja explains TENO Bioworks’ approach to performing a metabolic “heart transplant” on Escherichia coli (E. coli). They successfully rewired E. coli to utilize methanol as its primary carbon and energy source. We also dive into the downstream engineering required to produce target chemicals like lactic acid, the advantages of using raw, unpurified methanol over traditional metal catalysts.

In this episode of Innovate and React, I welcome back Thomas Bouveyron from and TH Köln to explore how we can make conventional petrochemical pathways more sustainable. We look into the synthesis of n-decanal, which is a crucial molecule in the fragrance industry and a key scent in Chanel No. 5. Thomas’ gaol is to shift from crude oil- to bio-based building blocks. How do you bend the rules of classical Wacker oxidation to favor the usually unfavored anti-Markovnikov product? Thomas shares his methodology, combining statistical Design of Experiments (DOE) and computational Density Functional Theory (DFT) calculations to unravel more of the catalytic mechanism. We also discuss the practical engineering hurdles of catalyst fatigue, solvent participation, and the tricky business of separating decanal from decanone.

In this episode of Innovate and React, host I sit down with Jonas Massa, co-founder of AKROS Energy, to tackle the pressing challenges of hydrogen storage and transportation. While green hydrogen is a promising energy carrier for fluctuating renewables, its highly flammable nature poses significant safety and regulatory hurdles, especially for decentralized applications involving non-specialist personnel. Jonas breaks down why conventional storage methods, like highly pressurized vessels or toxic ammonia, fall short for widespread, small-scale use.
To solve this, AKROS Energy is developing a revolutionary method that stores hydrogen in everyday, non-toxic salts, namely potassium bicarbonate and potassium formate. Jonas explains their streamlined, low-temperature catalytic process and they want to scale it up. A great alternative to Ammonia and LOHC.
