Hydrogen

The first diesel made from air and water (Photo: Audi)

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

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.  Read More

The BE-3 engine recently completed its acceptance testing

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 as it may have looked 4.5 billion years ago (Image: European Southern Observatory)

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

The Upp hydrogen fuel cell mobile charger

Portable hydrogen-powered fuel cell chargers, such as the Horizon MiniPak, have been around for a few years now. The Upp ups the capacity offering 25 Wh and works in conjunction with an companion app that provides device info and details of locations to find new cartridges.  Read More

Dr. Michio Kaku speaks at Toyota's CES 2015 press conference

Toyota is serious about hydrogen fuel cell technology. It's so serious that it's not only welcoming competition, it's helping it. At this year's Consumer Electronics Show, the automaker announced that it will open more than 5,500 fuel cell patents and provide royalty-free licenses to other automakers and entities.  Read More

Green concept cars 2014

Not only was 2014 a great year for sports concepts, it was a great year for green cars. Environmentally friendly production cars like the Toyota Mirai fuel cell vehicle and Volkswagen Golf GTE made their debuts and numerous concepts provided a window into a cleaner commuting future, showcasing technologies that will get us from point A to point B without so much impact on the rest of the alphabet. Here are our favorite green concept cars from the year.  Read More

The latest findings indicate that the Earth's water may not have come from comets (Image E...

The oceans are a mystery in more ways than one, but you might not expect the answers to come from a pack of electronics and a comet. But that's what the European Space Agency (ESA) says about the unmanned Rosetta probe orbiting comet 67P/Churyumov–Gerasimenko. Though 67P is making its first visit to the inner Solar System and won't come closer to the Earth than hundreds of millions of miles, it is throwing new light on one of the fundamental questions in Earth's history: Where did the oceans come from?  Read More

Researchers have achieved a solar energy to hydrogen conversion efficiency of 12.3% using ...

Using solar energy to split water into its component parts, thereby allowing the solar energy to be stored as hydrogen fuel, generally involves one of two methods: using photoelectrochemical cells to directly split the water, or using solar cells to produce electricity to power an electrolyzer that separates the water molecules. One problem associated with the latter method is that it currently relies on rare metals. But now scientists from Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland have managed to do so using common materials, and have achieved a record solar energy to hydrogen conversion efficiency in the process.  Read More

The Audi A7 Sportback h-tron quattro

One of the biggest tech stories at this year's LA Auto Show was the fuel cell car. Toyota led the way by launching the Mirai, and Volkswagen slid a fuel cell powertrain into the Golf SportWagen. Audi showed a sportier, more luxurious side to fuel cells in the A7 Sportback h-tron quattro. Ingolstadt calls it the "first performance fuel cell vehicle."  Read More
