New Method Could Help Get To Cheap Hydrogen

Using a PEM electrolyzer, the researchers create hydrogen in the laboratory. Credit: Eduardo Gracia Researchers at Umeå University have made a breakthrough that could make hydrogen, a carbon dioxide (CO2)-free fuel, more affordable. The team has created a new method to increase the production of hydrogen gas from water and electricity, a process critical to...

Solar Dish Produces Hydrogen and Oxygen and Heat

The pivotal component in EPFL's innovative solar hydrogen reactor is the parabolic dish. EPFL engineers have successfully constructed and examined a solar reactor capable of harnessing sunlight and water to produce hydrogen gas. This system not only exhibits exceptional efficiency in hydrogen generation but also effectively utilizes the byproducts of oxygen and heat. Hydrogen has a...

The Green Hydrogen Time, as a Renewable Energy Sources

All we are longing for is a less polluted environment. Credit Pexels. Green hydrogen is a form of hydrogen produced using renewable energy sources, such as wind or solar power, rather than fossil fuels. It is considered a promising solution for reducing greenhouse gas emissions and achieving a more sustainable energy future. Green hydrogen is...

Superaerophobic Polyethyleneimine Hydrogels Improve Electrochemical Hydrogen Manufacturing by Promoting Bubble Detachment

The scheme for a mechanism of bubble-detachment. a) Normal flat electrode, b) the problems of adhered bubbles, and c) various approaches for the removal of gas bubbles. In (a), R, ρ, g, and λ indicate the dimension of bubbles, the density of a solution, gravitational acceleration constant, and surface tension of a solution, respectively....

Retrofitted Diesel Engines to Use Hydrogen as Fuel, Increasing Efficiency by 26%

The hydrogen-diesel direct injection dual-fuel system developed at UNSW enables a traditional diesel engine to be retrofitted to run as a hydrogen-diesel hybrid engine. Credit: Prof. Shawn Kook Engineers at the University of New South Wales (UNSW) have retrofitted a diesel engine to use hydrogen as a fuel. Resulting in a reduction in carbon emissions,...

New Iron Catalyst Can Make Hydrogen Fuel Cells Affordable

Credit: Unsplash/CC0 Public Domain For decades, scientists have been seeking a catalyst that dramatically lowers the price of fabricating hydrogen fuel cells. Such an advance could trigger a green power transformation, with everything from laptops to locomotives running on a fuel whose merely byproduct is water. A new study led by the University at Buffalo indicates that...

Transforming ‘Drain Gas’ Into Clean Hydrogen Fuel

An odoriferous, toxic gas can now be converted into clean-burning petroleum using a brand-new chemical process that has been found by specialists. The procedure converts hydrogen sulfide—more commonly known as "drain gas"—into hydrogen fuel and was recently described in the American Chemical Society publication ACS Sustainable Chemical Engineering. Hydrogen sulfide is a byproduct of industrial...

Cheaper Hydrogen Production

Electrolytic hydrogen manufacturing powered by renewable energy is viewed as an environmentally safe way to relieve international environmental and energy issues. In the journal Angewandte Chemie, a research study team presented a new and low-cost material for electrodes that may offer very efficient, energy-saving hydrogen production: porous, phosphorized CoNi2S4 yolk-shell nanospheres. The half-reactions of water...

New Nanomaterial Produces Clean Energy Hydrogen Gas From Seawater

Hydrogen fuel stemmed from the sea could be a bountiful and sustainable substitute to fossil fuels; however, the potential power source has been limited by technological obstacles, consisting of exactly how to harvest it. Scientists at the University of Central Florida designed for the very first time a nanoscale material that can successfully divide seawater...

Jupiter Has No Surface. Here’s How That’s Possible

Credit: pixabay The planet Jupiter has no solid ground—no surface, like the grass or dirt we walk on here on Earth. There’s nowhere to land or walk on. But how is that possible? If Jupiter has no surface, then what does it have? How does it hold together? Even for a physics professor who studies unusual phenomena,...
