A new additive based on glycerol helps reduce pollution in marine bunker fuel used in crui...

The bunker fuel used in cruise liners and freighters is some of the cheapest, crudest fuel available. It’s also among the dirtiest. Scientists from the Maine Maritime Academy and SeaChange Group LLC led by George N. Harakas, Ph.D announced at the 244th National Meeting & Exposition of the American Chemical Society that they have developed what they call "Bunker Green" fuel. This fuel uses an ingredient commonly used in food and medicine to reduce sulfur and other emissions in ocean vessels.  Read More

Nanostellar has developed a mineral catalyst that outperforms platinum at a fraction of th...

Diesel engines are a classic example of good news and bad news. The good news is that diesel engines are much more fuel efficient than petrol engines. The bad news is that they belch out some pretty nasty emissions like nitric oxide and nitrogen dioxide. The good news is that catalytic converters can scrub those out. The bad news is that last Friday the platinum needed by the converters is selling for US$1,473.10 an ounce. Now the good news is that a team at Nanostellar in Redwood, California, has developed a mineral catalyst that outperforms platinum at a fraction of the cost.  Read More

Boeing Commercial Airplanes President and CEO Jim Albaugh, Embraer Commercial Aviation Pre...

Three of the world’s biggest aircraft manufacturers have set aside their differences in an effort to accelerate the development of biofuel for commercial aviation. In a Memorandum of Understanding (MoU) signed this week, Boeing, Airbus and Embraer say they have agreed to work together on the development of drop-in, affordable aviation biofuels that will help the aviation industry reduce its carbon footprint.  Read More

Scania trucks will soon offer Active Prediction

As useful as GPS is in the modern world, we're really only at the tip of the iceberg when it comes to some of the potential functionality of satellite-based navigation. The Active Prediction system under development at Scania, a member of Volkswagen AG, is one example. The system fuses GPS and cruise control, allowing the vehicle to predict terrain features of the road ahead and help to boost gas mileage.  Read More

The toilet trike will hit the Japanese roads in the coming days, making its way from Kyush...

If you think this smells like a PR stunt, you're right. In an effort to raise awareness about bathroom emissions and water savings, Japanese toilet manufacturer TOTO has created the Toilet Bike Neo Project ... yep, it's a road-going, three-wheeled toilet fueled by "biogas" generated from the toilet waste.  Read More

The drilling of an injection well in Decatur, Illinois that will be part of the first larg...

While some see carbon capture and storage as akin to sweeping CO2 emissions under the carpet, others believe it is a necessary short-term solution in the transition to a clean energy future. Last week, ground was broken on construction of the U.S.'s first large-scale industrial carbon capture and storage (ICCS) facility that aims to demonstrate that CO2 emissions can be stored permanently in deep underground rock formations.  Read More

Ford and SunPower have teamed up to offer rooftop solar panels to Ford EV buyers

Although electric vehicles can claim to be greener by producing zero local emissions, the electricity used to charge their batteries needs to come from somewhere. For most people, that somewhere is usually a fossil fuel-powered power station, lessening the green credentials of such vehicles. In an effort to let drivers go the extra green mile, Ford and solar technology company SunPower have teamed up to offer buyers of Ford's upcoming EVs a discounted rooftop solar system to provide enough renewable energy to offset the electricity used to charge the vehicles.  Read More

Gemasolar CSP plant

The Gemasolar Concentrated Solar Power (CSP) plant near Seville, Spain, has achieved a full 24 hours of solar power production one month after starting commercial operation. The 19.9 MW plant uses a huge array of mirrors to heat a molten salt storage system in the central tower which is then used to run steam turbines, resulting in the ability to continue energy production after the sun goes down.  Read More

Gulfstream G450 crosses the Atlantic on 50/50 biofuel-jetfuel blend

With the rising price of fuel and more stringent emissions regulations, there is a strong need for the aviation industry to begin taking steps to earn its green wings. It's not surprising therefore that biofuel was one of the hot topics at this week's Paris Air Show with both Boeing's 747-8 and Gulfstream's G450 business jet making the trip across the Atlantic on biofuel blends. The G450 flew in from Morristown, New Jersey, after a seven hour flight in which one of its Rolls-Royce engines was powered by a 50/50 blend of Honeywell Green Jet Fuel and petroleum-based jet fuel.  Read More

Spark plugs could soon be replaced be laser igniters

Internal combustion engines are likely to remain in widespread use for some time yet, but it's possible that we may be bidding adieu to that most iconic of engine parts, the spark plug. Researchers from Japan's National Institutes of Natural Sciences (NINS) are creating laser igniters that could one day replace spark plugs in automobile engines. Not only would these lasers allow for better performance and fuel economy, but cars using them would also create less harmful emissions.  Read More
