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

Toyota fuel cell bus tested in Tokyo

Toyota and Hino Motors have begun testing a jointly-developed fuel cell bus in Tokyo, Japan. The brief test is designed to will help Toyota evaluate and improve the technology ahead of a possible market launch. Read More

BMW explores hydrogen fuel cell power in new 5 Series GT prototype

Hydrogen has been touted as one of the most promising alternatives to our current dependence on fossil fuels to power cars because it fits our current driving habits. Whereas plug-in electric vehicles have limited range and take a long time to recharge, hydrogen fuel cell electric vehicles can be refueled in a matter of minutes from a pump that looks similar to a fuel pump. BMW has continued its development of hydrogen technology with a new 5 Series GT based prototype, which can drive for 500 km (311 miles) before it needs to be topped up.Read More

Solar-powered hydrogen generation using two of the most abundant elements on Earth

One potential clean energy future requires an economical, efficient, and relatively simple way to generate copious amounts of hydrogen for use in fuel-cells and hydrogen-powered vehicles. Often achieved by using electricity to split water molecules into hydrogen and oxygen, the ideal method would be to mine hydrogen from water using electricity generated directly from sunlight without the addition of any external power source. Hematite – the mineral form of iron – used in conjunction with silicon has shown some promise in this area, but low conversion efficiencies have slowed research. Now scientists have discovered a way to make great improvements, giving hope to using two of the most abundant elements on earth to efficiently produce hydrogen.Read More

Audi just created diesel fuel from air and water

Audi is looking to fuel the future without fossil fuels. One of the company's pilot plants in Germany has just produced the first batches of a synthetic diesel made using only water and air. The company's pilot plant, which is operated by German startup Sunfire, produced its first batches of the "e-diesel" this month. German Federal Minister of Education and Research Johanna Wanka put a few liters of the fuel in her work car, an Audi A8, to commemorate the accomplishment.Read More
