Vattenfall and Aalborg University are partnering with Danish startup SCF Technologies in a two-year project to design a demonstration plant based on SCF’s CatLiq process—an application of the firm’s supercritical fluid technology in the catalytic production of bio-oil from organic waste. The oxygen content of the CatLiq bio-oil is 2-12%.
Australia-based Hysata, which is commercializing capillary-fed electrolysis technology developed at the University of Wollongong ( earlier post ) has closed its oversubscribed Series A funding round of $42.5 The porous, hydrophilic separator sustains the flow rate required for water electrolysis. million AUD (US$30 million).
Northern Denmark Strait showing newly discovered deep current, in relation to known pathway. As part of the planet’s reciprocal relationship between ocean circulation and climate, the AMOC transports warm surface water to high latitudes where the water warms the air, then cools, sinks and returns toward the equator as a deep flow.
Scientists from Stanford University, SLAC National Accelerator Laboratory and the Technical University of Denmark have identified a new nickel-gallium catalyst that converts hydrogen and carbon dioxide into methanol at ambient pressure and with fewer side-products than the conventional catalyst. Resources.
By means of time-lapsed high-resolution scanning tunneling microscopy (STM), corroborated by density functional theory calculations, a team of researchers at Aarhus University (Denmark) has recorded all the intermediate steps for a surface-catalyzed reaction—specifically, the oxidation of H adatoms by O 2 molecules on a TiO 2 (110) surface.
Ruthenium dioxide is widely used in industrial processes, in which it’s particularly important for catalyzing the oxygen evolution reaction (OER) that splits molecules of water and releases oxygen. I think the exciting aspect of the work is that we push a little bit the boundary of our understanding of the catalysis of splitting water.
Some 29% of all historic seagrass meadows have been destroyed, mainly due to dredging and degradation of water quality. —co-author Karen McGlathery, a scientist at the University of Virginia and NSF’s Virginia Coast Reserve LTER site. The research also estimates that, although seagrass meadows occupy less than 0.2% At least 1.5%
If the present warming trend continues, melt-water from the Greenland ice sheet will contribute to a sea-level rise of around 1 meter in this century—together with melt-water from other ice sheets and ocean thermal expansion. The mass-loss has been accelerating in the last couple of years.
The clean technology company Danish Power Systems (DPS), with partners at the Technical University of Denmark (DTU) and the University of Chemistry and Technology in Prague, Czech Republic, reports the best operating stability for high-temperature polymer fuel cells (HTPEMFC) yet. μV h −1 for a reference membrane.
Researchers from Chalmers University of Technology and Technical University of Denmark have shown that thin alloy films of single-target co-sputtered platinum-yttrium exhibit up to 7x higher specific activity (13.4 ± 0.4 The nanometer-thin alloy films effectively transform oxygen (red) and protons (white) into water.
Honda next year will offer Californians futuristic sedans that can travel 300 miles (480 km) or more on a tank of hydrogen gas while emitting nothing more toxic than pure water vapor. Most recently, Toyota announced that its fuel cell sedan would also be available in the UK, USA, Germany and Denmark during the summer of 2015.
Risø DTU, the National Laboratory for Sustainable Energy at the Technical University of Denmark - DTU, is heading an effort to transform CO 2 and renewable electricity into synthetic fuels for transportation. Through electrolysis, water is transformed into hydrogen and oxygen (and CO 2 to CO and oxygen) using electricity.
has ordered 10 Serenus high-temperature (HT) 3kW PEM fuel cell systems from Denmark-based Serenergy A/S for use in Microcab’s next generation of demonstration fuel cell hybrid vehicles. There is no liquid water in a HTPEM MEA and therefore there is no need for a compressor. A Microcab urban car. Click to enlarge. No compressor.
A team of researchers at Sandia’s Combustion Research Facility and the Technical University of Denmark have developed an optical setup for quantitative, high-temporal resolution line-of-sight extinction imaging in harsh optical environments. —lead author Fredrik Westlye.

But we do actually need that energy to be generated,” says Alper Bozkurt, who with Veena Misra codirects the Center for Advanced Self-Powered Systems of Integrated Sensors and Technologies (ASSIST) at North Carolina State University. But solar is just the opening gambit. volts for about 60 hours.
Natura Resources and Abilene Christian University , both in Abilene, Texas, are collaborating on a 1-MW liquid-molten-salt reactor after receiving a construction permit in September from the U.S. Denmarks Copenhagen Atomics , for example, currently aims to develop a thorium-based molten-salt reactor, with a 1-MW pilot planned for 2026.
Goh, Ufuk Topcu, and Avinash Balachandran from University of Texas at Austin, USA, and Toyota Research Institute, Los Altos, Calif., 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.
An injection well pumps water into this hot layer where it is turned to steam. Kammen, a professor in the Energy and Resources Group at the University of California, Berkeley. Here’s the scoop: Engineers drill a hole about 6,000 feet down where the magma has heated the surrounding area to about 400-500 degrees Farenheit.
They’ve also discovered that a huge quantity of water is necessary to put out an EV fire, so they’ll be prepared with a larger fleet of water tenders. The use of massive amounts of water, primarily to cool the batteries, or simply let the fire burn itself out is common in all procedures.
Royal DSM, together with DONG Energy (Denmark), has demonstrated the combined fermentation of C 6 and C 5 sugars from wheat straw on an industrial scale. The aim is to: Reduce the energy consumption; Improve the water balance; Add a fermentation step for C 5 sugars; Reduce the enzyme consumption; and. Earlier post.) Earlier post.)
Topsoe will lead the FrontFuel project to develop highly efficient Sustainable Aviation Fuel (SAF) production from CO 2 , water, and renewable electricity. million DKK (US$4 million) grant from Denmark’s EUDP (Energy Technology Development and Demonstration Program) to fund the project. Topsoe will receive a 26.9
Researchers at Chalmers University of Technology have shown that between 87 and 98 percent of ships comply with the tougher regulations for sulfur emissions that were introduced in northern Europe in 2015. Other patterns we can see are that vessels that only rarely come into these waters break the rules more frequently.
The EU-funded research project HyFlexFuel recently successfully produced biocrudes via hydrothermal liquefaction (HTL) from a variety of biomasses, including sewage sludge, food waste, manure, wheat straw, corn stover, pine sawdust, miscanthus and microalgae in a pilot-scale continuous HTL plant at Aarhus University (Denmark).
I would say that electricity is a vastly superior fuel for the light vehicle fleet,” said Willett Kempton , a professor and alternative energy specialist at the University of Delaware. So far Israel, Denmark, Australia , Hawaii and California’s Bay Area have plans to implement the Better Place model.
Now in its twentieth year, the biennial report is produced by researchers at Yale and Columbia Universities in collaboration with the World Economic Forum.
