Layer of strange "dark hydrogen" believed to exist on Jupiter-like planets

As the most abundant element around and the basis for a full three-quarters the mass of the universe, you'd think scientists would have uncovered all there is to know about hydrogen. Apparently, they haven't, as researchers at the Carnegie Institution for Science have just produced a third version of the element in a lab, that they believe is found on gas giant planets like Jupiter and Saturn. They're calling it dark hydrogen. Read More

Mercedes flags 500 km EV platform, wireless charging and a hydrogen hybrid

As alternative powertrains move towards the mainstream, there is increasing pressure to create versatile platforms capable of handling a range of propulsion systems without huge development costs on each individual model. Volvo has SPA, Volkswagen has MQB and now Mercedes has used TecDay in Stuttgart to announce a dedicated platform for pure electric cars, alongside plans for wireless EV charging and a hydrogen plug-in hybrid SUV.

Miniature fuel cell to keep drones aloft for over an hour and phones charged for a week

Drones are being utilized in everything from parcel delivery to search and rescue, but their limited flight times are restricting their ability to travel great distances or stay for extended periods of time in the field. Simply adding more batteries, however, affects flight characteristics and reduces the load the drone can carry. To help solve this problem, researchers at the Pohang University of Science and Technology (Postech) have created a miniature fuel cell they claim not only provides enough energy to keep a drone in the sky for over an hour, but may well find applications in powering everything from smartphones to cars in the not-too-distant future.Read More

New process produces hydrogen from methane, without emitting CO2

Natural gas accounts for over 28 percent of US energy consumption. Its main component, methane, is a widely-used fossil fuel but also a major contributor to rising CO2 levels, and thus climate change. To address this issue, researchers from the Institute of Advanced Sustainability Studies (IASS) and Karlsruhe Institute of Technology (KIT) have developed a process that extracts the energy content of methane, in the form hydrogen, without producing carbon dioxide.Read More

GM, US Army extreme testing hydrogen fuel cell Colorado

General Motors and the US Army are joining forces to put hydrogen fuel cell technology to the test in extreme military environments. The project will see the Army's Tank Automotive Research, Development and Engineering Center (TARDEC) run a 12 month test on a Chevrolet Colorado pickup truck modified to run on a commercial hydrogen fuel cell and electric powertrain.Read More

Hybrid artificial photosynthesis technique produces hydrogen and methane

Not content with using hybrid artificial photosynthesis to turn CO2 emissions into plastics and biofuel, researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) now claim to have produced an enhanced system that uses water and solar energy to generate hydrogen, which is in turn used to produce methane, the main element of natural gas, from carbon dioxide. Generating such gases from a renewable resource may one day help bolster, or even replace, fossil fuel resources extracted from dwindling sub-surface deposits.Read More

New record energy efficiency for artificial photosynthesis

As the world moves towards developing new avenues of renewable energy, the efficiencies of producing fuels such as hydrogen must increase to the point that they rival or exceed those of conventional energy sources to make them a viable alternative. Now researchers at Monash University in Melbourne claim to have created a solar-powered device that produces hydrogen at a world-record 22 percent efficiency, which is a significant step towards making cheap, efficient hydrogen production a reality.Read More
