Sustainable fuels and basic chemicals for Switzerland

Developing robust supply paths for sustainable fuels and basic chemicals for Switzerland is the aim of the "reFuel.ch" consortium funded by the Swiss Federal Office of Energy (SFOE), which held its kick-off event on 8 December 2023. The consortium comprises nine Swiss universities, universities and research institutes from various disciplines as well as an industrial partner. As time is pressing for climate-friendly solutions, political decision-makers will also be involved.

A Memorandum of Understanding on sustainable energy and energy technologies was signed during the visit of Swiss President Alain Berset to Oman and Empa researcher Christian Bach, as co-coordinator of reFuel.ch, was able to receive a corresponding "Letter of Interest" from the Omani Ambassador to Switzerland, H.E. Mahmood Al Hassani, for a corresponding collaboration; the reFuel.ch consortium has therefore arrived at just the right time. Although these are only the first steps on the long road to supplying Switzerland with sustainably produced fuels and basic chemicals, they demonstrate the international dimension of reFuel.ch, which brings together more than 60 project partners from the entire value chain.

The signing has already been followed by the first concrete steps. For example, a reFuel.ch delegation of 15 business and research representatives will be travelling to Oman in December to hold talks with the Omani Ministry of Energy and Minerals on the sidelines of the Green Hydrogen Summit there. The talks will focus on the development of approaches for the production of sustainable energy sources and basic chemicals as well as regulatory and market solutions.

Another - European - case study will soon be launched in southern Spain. At the same time, the efficiency and therefore also the costs of currently available processes for the production of sustainable energy sources are to be significantly improved. As a centre of research and technology, Switzerland can make an important contribution to solving the global climate problem.

International cooperation for more efficient production

The SFOE-funded consortium is investigating how fossil fuels can be replaced by sustainable energy sources, for example in aviation and industrial processes. The majority of these will come from abroad. Countries in the Earth's Sun Belt could play an important role here. Accordingly, the researchers will be looking closely at foreign production, regulatory and legal framework conditions and the issue of dependency. In order for Switzerland to meet its demand for sustainable fuels and basic chemicals amounting to 30 to 60 terawatt hours (approx. 3 to 6 billion litres of diesel equivalent), it needs a PV area of 200 to 400 km2 on site, which is slightly less than the area of Lake Constance. Two to three times more electricity can be generated per square metre of PV area in the Sun Belt than in Switzerland. In future, the electricity generated in this way will be the energy basis for the production of sustainable fuels and basic chemicals.

Within Switzerland, the consortium is focussing on the increased energetic use of farmyard manure (especially slurry) for further development into gaseous or liquid energy sources and on increasing the efficiency of production processes for synthetic fuels.

Global cost drivers and regional trade-offs for low-carbon fuels: a prospective techno-economic assessment

Low-carbon fuels (LCFs) such as green hydrogen, synthetic hydrocarbons, and biofuels are critical for decarbonizing sectors that are difficult to electrify. In this study, we present a globally harmonized techno-economic assessment of 21 LCF production pathways, including power-to-X, biomass- and sun-to-liquids, and multiple hydrogen routes, evaluated across all countries under three future scenarios for 2024, 2030, and 2050. The model integrates spatially explicit resource data, learning-driven capital cost trajectories, and dynamic, country- and technology-specific costs of capital, supported by robust scenarios and uncertainty analysis. By 2050, median levelized costs are projected to range from 0.07 to 0.10 EUR2024 per kWh for green hydrogen, 0.15 to 0.18 EUR2024 per kWh for power-to-liquid kerosene, and 0.14 to 0.20 EUR2024 per kWh for most bio-based aviation fuels, reflecting both substantial progress and persistent regional disparities. Our results show that while innovation, technology learning, and deep power sector decarbonization can unlock cost-competitive electrofuels in countries with abundant renewables, bio-based routes are frequently cost competitive for sustainable aviation fuel (SAF) production in near-term scenarios, and solar-to-liquid fuels remain constrained by feedstock availability and capital barriers. Nuclear- and methane-based hydrogen emerge as primary options in many regions, as well as the dominance of turquoise hydrogen in Russia, the Middle East, and Central Asia where carbon management is viable, which highlights the context-specific nature of future LCF systems. We also found that the least-cost logistics for global hydrogen trade will shift from ammonia shipping to pipeline transport and methanol delivery, with North Africa and Iberia emerging as leading suppliers to Europe. These findings underscore the need for integrated innovation, policy coordination, and investment strategies that address both resource and financial barriers, in order to achieve scalable, resilient, and cost-effective LCF supply chains worldwide.

Active Phase–Support Interaction in Phosphotungstic Acid-SiO2 Catalysts Enables Enhanced Olefin Oligomerization to Synthetic Fuel

Transitioning the aviation sector to synthetic aviation fuels (SAF) requires innovative catalytic processes to overcome common limitations such as insufficient activity, selectivity, and catalyst deactivation. This study presents a detailed exploration of silica-supported phosphotungstic acid (PTA/SiO2) as a robust solid acid catalyst for propylene conversion into jet fuel-range hydrocarbons (C8 to C16) at mild reaction conditions (150 °C). The catalyst with optimized PTA loading (10 wt %) demonstrates significant oligomerization performance, achieving high selectivity to jet fuel-range hydrocarbons (>80%) and propylene conversion (>90%), alongside limited aromatic byproducts formation. Compared to conventional solid-acid catalysts such as a ZSM-5 zeolite, PTA/SiO2 exhibits significantly reduced catalyst deactivation and can be regenerated through mild thermal treatment (<400 °C). Detailed structural characterization revealed that PTA island size influences product selectivity. Increasing the PTA weight loading leads to larger active phase island sizes, with larger PTA islands preferentially producing longer-chain hydrocarbons (C15+). Raman spectroscopy confirms the preservation of the PTA Keggin structural integrity across all catalyst loadings, although perturbations in terminal W═O vibrations occur due to interactions with the SiO2 support. Crucially, insights obtained through combined XPS/HAXPES analyses reveal significant electronic interactions between PTA and SiO2, characterized by pronounced bending of the energy bands at the interface between semiconducting PTA and insulating SiO2. This effect generates interfacial tungsten states, which enhance localized electron mobility and facilitate proton transfer, significantly amplifying catalytic activity. Even catalysts with minimal Brønsted acidity (1 wt % PTA loading) exhibit notable turn over, emphasizing interfacial electronic modulation, rather than bulk acidity alone, as an important performance descriptor in olefin oligomerization.
