Hybrid artificial photosynthesis technique produces hydrogen and methane

By - August 25, 2015 2 Pictures

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.

New record energy efficiency for artificial photosynthesis

By - August 20, 2015

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.

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

By - July 3, 2015 33 Pictures

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.

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

By - June 23, 2015

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.

Audi just created diesel fuel from air and water

By - April 26, 2015 7 Pictures
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

Researchers produce hydrogen quickly and cheaply using plant waste

By - April 9, 2015
Hydrogen is the ideal gas for use in low-emissions combustion engine or fuel cell-powered vehicles, due to its almost non-existent greenhouse gas emissions. Production costs, however, are higher compared to gasoline and around 95 percent of it is currently produced, somewhat counter-intuitively, from fossil fuels. Now researchers at Virginia Tech claim to have created a method to produce hydrogen fuel using a biological technique that is not only cheaper and faster, but also produces hydrogen of a much higher quality ... and all from the leftover stalks, cobs, and husks of corn.

Blue Origin's BE-3 engine cleared for flight

By - April 8, 2015 4 Pictures
Blue Origin has taken a step closer to lifting into space by announcing that its BE‑3 rocket engine has completed acceptance testing, opening the door to its first flight. The first new hydrogen engine to be developed in the US in over a decade, the BE-3 is part of Blue Origin's program to develop a completely reusable launch system. Read More

Mars may have had more water than the Arctic Ocean

By - March 9, 2015 2 Pictures
In Edgar Rice Burroughs's Barsoom novels, Earthman John Carter's adventures took place on the dry beds of Mar's ancient oceans. Now NASA scientist's say that may not be so far fetched. Though they haven't found signs of any thoats, they have estimated that Mars may once have had enough water to form a vast ocean surrounding its north pole of which only plains remain. Read More
