A research group composed of Dr. Martin Prechtl, Leo Heim and their colleagues at the University of Cologne's Department of Chemistry has discovered a new method of generating hydrogen using water and formaldehyde. The generation of hydrogen from liquids is of particular interest when it comes to fuel cell technologies. The results of the project, entitled "Selective and mild hydrogen production using water and formaldehyde", have recently been published in the journal Nature Communications.

Researcher seeks upgrades for cleaner oilsands
We live in a province rich in fossil fuel resources, and great profits can be made from them. However, the use of these fossil fuels comes at a significant environmental cost. The greenhouse gas emissions footprint of Alberta's oilsands industry is one of its most formidable challenges in the context of environmental stewardship.

Modified algae enzymes enable efficient hydrogen production
(Phys.org) —Hydrogen as a regenerative fuel produced in gigantic water tanks full of algae, which need nothing more than sunlight to produce the promising green energy carrier: a great idea in theory, but one that fails due to the vast amount of space required for the production process. Scientists from the Max Planck Institutes for Chemical Energy Conversion and Coal Research) in Mülheim an der Ruhr, and from the research group Photobiotechnology at Ruhr-Universität Bochum (RUB) have now discovered a way of increasing the efficiency of hydrogen production in microalgae by a factor of five. If the algae can generate the fuel more efficiently, it can be produced in a smaller area and in quantities suitable for practical use. This approach also dispenses with the need for rare and expensive precious metals, which are used to split the energy-rich gas is technically from water.

Moving toward a cheaper, better catalyst for hydrogen production
(Phys.org) —Hydrogen could be an important source of clean energy, and the cleanest way to produce hydrogen gas is to split water into hydrogen and oxygen. But the catalyst currently used to facilitate this water-splitting reaction is platinum. And that's a problem.

Renewable energy obtained from wastewater
Researchers from the Universitat Autònoma de Barcelona have devised an efficient way to obtain electrical energy and hydrogen by using a wastewater treatment process. The proposed system, published in Water Research, uses bacteria which consumes the organic material and produces electricity, which produces hydrogen, the energy vector of the future. The results point to further developments of this technology at industrial scale.

New discovery may be breakthrough for hydrogen cars
A team of Virginia Tech researchers has discovered a way to create hydrogen fuel using a biological method that greatly reduces the time and money it takes to produce the zero-emissions fuel. This method uses abundantly available corn stover - the stalks, cobs, and husks - to produce the hydrogen.

Fast-fill hydrogen fueling station enabling zero emission transportation
The Hawai'i Natural Energy Institute (HNEI) has commissioned a "Fast-Fill" high-pressure hydrogen fueling station at the Marine Corps Base Hawai'i (MCBH), Kaneohe Bay. This state-of-the-art station was developed to support a fleet of General Motors Equinox Fuel Cell Electric Vehicles (FCEV) leased by the Office of Naval Research for use by Marine Corps and Navy personnel on O'ahu. Operational since November 2014, this station was recently certified for unattended operation, allowing drivers to self-fill their cars just as they would do at any gasoline fueling station. Unattended operation will serve as a model for the installation of private stations throughout the state.

'Salted' catalysts for chemical energy storage: Basic alkali-metal salts improve catalyst for methanol steam reforming
(Phys.org) —The storage of hydrogen in the form of methanol is a highly promising method for using excess energy produced by wind and solar power plants. However, this technology requires an effective catalyst for regenerating the hydrogen. German scientists have now introduced a new platinum catalyst for this reaction, known as the steam reforming of methanol, in the journal Angewandte Chemie. The secret of their success lies in a special coating made from molten basic alkali metal salts.

Producing hydrogen from water with carbon / charcoal powder
In the latest advance in efforts to find an inexpensive way to make hydrogen from ordinary water—one of the keys to the much-discussed "hydrogen economy"—scientists are reporting that powder from high-grade charcoal and other forms of carbon can free hydrogen from water illuminated with laser pulses. A report on the discovery appears in ACS' Journal of Physical Chemistry C.

Novel technology produces gasoline by metabolically-engineered microorganism
For many decades, we have been relying on fossil resources to produce liquid fuels such as gasoline, diesel, and many industrial and consumer chemicals for daily use. However, increasing strains on natural resources as well as environmental issues including global warming have triggered a strong interest in developing sustainable ways to obtain fuels and chemicals.

Organic framework serves as a catalyst for the photocatalytic conversion of water into hydrogen
Humanity's need for energy is ever-increasing. However, the traditional energy sources are finite. In contrast, water and sunlight are available in vast abundance. Scientists at the Max Planck Institute for Solid State Research in Stuttgart and from LMU Munich have now created a material that uses light to produce the versatile energy source hydrogen from water. This polymeric photocatalyst is chemically stable. Moreover, the rate of hydrogen production can be fine-tuned by means of small structural modifications of the catalyst.
