Researchers use chemical looping process to produce hydrogen from hydrogen sulfide gas

Green Car Congress

Researchers at The Ohio State University have used a chemical looping process to produce hydrogen from hydrogen sulfide gas—commonly called “sewer gas”. Hydrogen sulfide is emitted from manure piles and sewer pipes and is a key byproduct of industrial activities including refining oil and gas, producing paper and mining.

New nanolithia cathodes may address technical drawbacks of Li-air batteries; scalable, cheap and safer Li-air battery system

Green Car Congress

An international team from MIT, Argonne National Laboratory and Peking University has demonstrated a lab-scale proof-of-concept of a new type of cathode for Li-air batteries that could overcome the current drawbacks to the technology, including a high potential gap (>1.2 V) V in O 2 (gas) → O x− (condensed phase), and η charging > 1.1

Power-to-gas trial to inject hydrogen into Australia’s gas grid; A$5M award to AquaHydrex

Green Car Congress

The Australian Renewable Energy Agency (ARENA) announced a trial for a new type of electrolyzer which could see excess renewable energy stored in the gas grid and used to decarbonize Australia’s gas supply. Storing renewable energy directly in the gas network was a logical first route to market for the invention.

Pneumatic Actuators Give Robot Cheetah-Like Acceleration

Cars That Think

Electric motors have helped bring legged robots into the mainstream, offering a straightforward and compact way of controlling robotic limbs with all the fancy control features you need for safe and nimble motion. But to make a robot run like a cheetah, it turns out that complicated control may not even be necessary.

Stanford researchers develop new electrolysis system to split seawater into hydrogen and oxygen

Green Car Congress

Hongjie Dai and his research lab at Stanford University have developed a prototype that can generate hydrogen fuel from seawater. Developing cheap electrocatalysts and electrodes that can sustain seawater splitting without chloride corrosion could address the water scarcity issue. Image credit: Courtesy of H. —Michael Kenney.

.: A Reader,” which was co-edited by Raphael Heffron and Gavin Little and published by Edinburgh University Press. Collectively, the region harbors around half of the world’s conventional reserves of oil and natural gas. When it comes to energy, the Middle East is best-known as a supplier of commodities to the importing world.
