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 Swiss company Climeworks is building the world’s largest direct air capture (DAC) and storage facility for converting atmospheric CO 2 to rock in Iceland. Water from the Hellisheiði power plant then flows through the facility and transports the carbon dioxide roughly 2,000 meters below the surface of the Earth.
Michael Grätzel at EPFL (Ecole Polytechnique Fédérale de Lausanne) in Switzerland has developed a highly efficient and low-cost water-splitting cell combining an advanced perovskite tandem solar cell and a bi-functional Earth-abundant catalyst. Splitting water requires an applied voltage of at least 1.23 V and up to 1.5
From QUANTRON’s point of view, this combination, which has so far been rather rare in Europe, represents the optimal team for converting the energy on board into propulsion as safely and efficiently as possible. This range is fully sufficient for most transport operators, saving them greater expense on charging infrastructure.
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. We demonstrate in this study that, thanks to their high V OC , three series-connected SHJ cells can already stably drive the water splitting reaction at unprecedented SHE. Schüttauf et al.
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. Type of CO2 source (biogas; waste water; atmosphere). Dr. Christian Ehler, member of the European Parliament, is serving as sponsor to the project.
MAN Diesel & Turbo Schweiz AG has signed a cooperation agreement with ABB Switzerland for the development, production and commercialization of a three-way energy-storage system. The heat and cold can be converted back into electrical energy on demand. The CO 2 is fed into a heat exchanger and heats the water.
Methanization works by producing methane (CH 4 ) and water (H 2 O) by catalytic conversion from carbon dioxide (CO 2 ) and hydrogen (H 2 ). Water causes problems with conventional processes, however; to remove it, serial methanization stages are typically required—with condensation areas in between.
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). To produce it, the power-to-liquid plant converts surplus hydropower into synthetic fuel.
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.

—Thomas Fritschi, Managing Director of RENK-Maag in Winterthur The gear units are developed and built at the RENK site in Winterthur, Switzerland. In direct reduction, iron ore is converted into sponge iron with the help of a reducing agent. They are used in a direct reduction plant in Siemens compressors.
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”.
solar and wind), water and CO 2 to produce liquid or gaseous fuels with a very low carbon intensity. to the realization of the renewable energy + water + CO 2 formula. The Audi e-gas plant can convert 6MW of input power. The process to convert isobutene to isooctane is well-established. Earlier post.) Earlier post.).
What about a miniaturized water treatment plant? Within their R&D department, Eden Cleantech, they are developing a compact, energy-saving water treatment system to help tackle the growing presence of micropollutants in wastewater. This raises the question: How can a device made from CDs decontaminate water?
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 adsorbed water allows detection by neutrons. For neutron imaging, thermal (12 meV - 100 meV; 2.6 - 0.9 meV - 12 meV; 26.1 – 2.6
We propose a prototype with special designs for propulsion and thruster configuration to cope with the vast differences in the fluid properties of water and air. Our system converts raster or vector images into piecewise-continuous paths depending on stylistic choices, such as TSP art or stroke-based drawing.
By advanced nuclear, we were primarily talking about new reactor designs that differ from today’s typical water-cooled fission reactors. Nuclear Regulatory Commission (NRC) had for approving commercial reactor designs was based on light-water reactors, technology dating from the 1950s. At the time, the only framework that the U.S.
In my conversations, I focus primarily on the overall total cost of ownership and I have encouraged some friends to convert. They are expanding their charging infrastructure across the state, soon to be nationwide with key EV brands, and have just completed a partnership in Switzerland. Frederick (Rick) W. I am an educator at heart.

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.

hours; tickets from 34 Swiss francs, or about $38), I watched the soft slopes of Italy give way to Switzerlands craggy cliff faces. I headed to Cisternerne , an underground water reservoir transformed, with its open pools, into an unusual art space. I boarded the line to Zurich. On a spotless Swiss train (3.5
Along the border of France and Switzerland, around a hundred meters underneath the countryside, protons speed through a 27-kilometer ringabout seven times the length of the Indy 500 circuituntil they crash into protons going in the opposite direction. Finding a place to bury a 90-km ring is not easy, especially in Switzerland.
