Recently, c-Si modules have been implemented in solar-hydrogen devices, demonstrating SHE [solar-to-hydrogen efficiency] of 9.7%. As the V OC of the presented c-Si cells is only ∼600 mV, four cells need to be connected in series to achieve stable water splitting performance. Schüttauf et al. Schüttauf et al. Schüttauf et al.

Quantron AG is a system provider of clean battery and hydrogen-powered e-mobility for commercial vehicles such as trucks, buses and vans.
The pilot-scale HTL plant processes aqueous biomass slurries (~20% dry matter content) at temperatures up to 350 °C and pressures around 200 bar, where water does not boil but remains in a liquid state. Under these conditions, biomass is converted into a crude bio-oil, which is separated from the process water behind the reactor.
The Franche-Comté region and La Poste (the French postal service) are testing hydrogen fuel cell range extender kits from Symbio FCell in three Renault Kangoo Z.E. The Franche-Comté region borders on Switzerland, with the Vosges mountains to the north and the Jura to the south.). (The Symbio ALP-5 range extender. Click to enlarge.
By utilizing a redox material such as ceria (CeO 2 ) as a reactive medium, STCs can produce hydrogen and carbon monoxide—i.e., syngas—from water and CO 2. Schematic illustration of direct hydrocarbon (C x H y O z ) formation from water and carbon dioxide during the reoxidation of reduced ceria doped with a catalyst (Cat.).
The goal is to develop a process for producing kerosene from carbond dioxide and green hydrogen. Over the next three years, the two Swiss research institutes will jointly search for practical ways of linking carbon dioxide and hydrogen to form longer-chain molecules and thus produce synthetic fuels. million Swiss francs (US$6.9
Depletion of fresh water reserves [m 3 ]. A recent PSI study led by environmental scientist Christian Bauer found that a battery electric car is already the most environmentally friendly option in Switzerland and many other countries, even when the manufacture of the battery is figured in. Depletion of metal resources [kg iron-eq.].
While the current facility feeds pure hydrogen (“WindGas”) directly into the gas grid, the new methanation plant provides for the generation of “green” methane. In this second stage, hydrogen from regenerative energy sources is converted into methane (CH 4 ), i.e. synthetic natural gas, using CO 2 from a bio-ethanol plant.
All are invited to submit, from 25 June to 20 September, innovative scientific research projects using Essential Small Molecules on these topics: Topic #01 on hydrogen production: “Lower-CO 2 H 2 ”. How to produce cost competitive hydrogen while reducing greenhouse gas emissions?
Swiss research intsitute Empa’s future mobility demonstrator, “move”, is investigating three paths for CO 2 reduction in road traffic—electric mobility, hydrogen mobility and synthetic fuels—against the background of a rapidly changing energy system. Both hydrogen production and methanization continuously generate waste heat.
CO 2 and water are extracted directly from ambient air via an adsorption/desorption process. At the heart of the solar reactor is a ceramic structure made of cerium oxide, which enables a two-step reaction—the redox cycle—to split water and CO 2 into syngas.
Researchers from Oregon State University College of Engineering, with colleagues from Cornell University and the Argonne National Laboratory, have used advanced experimental tools to provide a clearer understanding of an electrochemical catalytic process that’s cleaner and more sustainable than deriving hydrogen from natural gas.
With our technology, our customers are able to switch to hydrogen-rich reduction gas without structural changes to the integral gear compressors. —Thomas Fritschi, Managing Director of RENK-Maag in Winterthur The gear units are developed and built at the RENK site in Winterthur, Switzerland.
Researchers from Germany and Switzerland have manufactured and characterized a novel aerogel catalyst that could significantly increase the efficiency and life of low-temperature polymer electrolyte fuel cells as well as reduce material costs by reducing the platinum loading required.

Researchers from Purdue University and École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland are proposing a new integrated process involving the co-production of hydrogen and electricity from solar thermal energy—a concept they label “hydricity”.
Together with the partners Ineratec GmbH ( earlier post ) and Energiedienst Holding AG , the company has plans for a new pilot facility for the production of e-diesel in Laufenburg, in Canton Aargau (Switzerland). This hydrogen, together with carbon dioxide, is converted in a two-step power-to-liquid process.
Researchers at EPFL in Switzerland have developed a system for producing hydrogen through a simplified membrane-less water electrolysis process. Two parallel plates are coated with hydrogen and oxygen evolution catalysts respectively and are separated by less than few hundreds of micrometers.
In an event in Bern, Switzerland, Swiss National Council member and president of the Clean Fuel Now initiative Thomas Böhni filled up his Audi A2 with 100% synthetic diesel (Audi e-diesel) produced by sunfire GmbH to draw attention to the need to remove what he terms unjustified Swiss restrictions on synthetic fuels. Earlier post.).
solar and wind), water and CO 2 to produce liquid or gaseous fuels with a very low carbon intensity. Underneath the e-fuels banner, Audi also includes renewable electricity for recharging its e-tron vehicles (“e-power”) and, should the market so require it, “green” hydrogen (e-hydrogen, derived in the e-gas process). Audi e-gas.

Neutrons (along with protons) are fundamental particles that constitute the nucleus of most atoms (hydrogen being the exception). Å, 152 – 1515 m/s) neutrons are preferred due to their favorable detection reactions and due to their very useful contrast behavior, note the scientists at the Paul Scherrer Institute in Switzerland.
The solutions Rahman outlined were the use of proven methods that reduce electricity usage, making coal plants more efficient, using hydrogen and other storage solutions, promoting more renewables, installing new types of nuclear reactors, and encouraging cross-border power transfers. It results in higher efficiencies: about 46 percent.
But fate had a different plan: Over the past two decades, he has been the prime mover behind transforming a local effort to make hydrogen the fuel of choice for rail transit into a global phenomenon. Furthermore, he suggested, the trains could be powered electrically by hydrogen. the Charlotte suburb he calls home. is up and running.
