Hydrogen

A team from Australia's RMIT University says it's figured out a cost-effective way to produce hydrogen using wastewater and sewage. The process not only produces clean H2 gas, it also captures all the carbon in human poop and puts it to valuable use.

Engineers at the University of Liverpool have developed a robot scientist that can autonomously perform experiments, analyze results and decide what to do next based on those results – and it’s already making new discoveries on its own

Solar-to-hydrogen cells can convert solar energy directly into hydrogen without needing an external electrolyzer, and an exciting new design out of the Australian National University has achieved record efficiency levels using low-cost materials.

A South Australian company is ready to go into full production with an innovative aftermarket kit that impressively cuts fuel consumption, particulates and carbon monoxide emissions from big diesel engines, asking only for a little water in return.

Greener than the best renewable hydrogen production processes, and as cheap as the dirtiest coal-generated H2 out of India – using garbage for fuel that would otherwise sit in landfill. Extraordinary claims for a new H2 plant planned for California.

Researchers at Rice University have built a simple new solar-powered device that can create hydrogen for fuel by splitting water. It's similar to other “artificial leaf” designs but the team says it’s self-sufficient and relatively cheap to produce.

Life continually outdoes expectations. A new study from MIT has found that E. coli and yeast can survive in an atmosphere made up of 100 percent hydrogen – and that could have fascinating implications for life on other planets.

Aiming to cut carbon dioxide emissions from new vehicles by 90 percent by 2050, Toyota has teamed up with Hino Motors to develop a heavy-duty fuel-cell truck with a range of 600 km.

Scientists at the Tokyo University of Science have used rust as a catalyst in light-assisted hydrogen production from organic waste, finding it produces 25 times more hydrogen than previous titanium dioxide catalysts.

Astronomers have analyzed the atmosphere of a large exoplanet and found that it could have liquid water – and so possibly life – on its surface. This new study adds weight to the idea that habitable exoplanets don’t have to be strictly Earth-sized.

Back in 2017, a former racing catamaran was turned into a floating clean energy laboratory. Powered by a mix of renewable energies, the striking vessel is now the first recipient of Toyota's new fuel cell system for maritime applications.

A new molecule developed by Ohio State University scientists can harvest energy from the entire visible spectrum of light, harnessing up to 50 percent more solar energy than current solar cells, and can also catalyze that energy into hydrogen.
