Researchers at Vanderbilt University have found a way to improve battery performance with iron pyrite nanocrystals. While nanocrystals, or quantum dots, have been used to charge batteries extremely quickly, the performance wanes after very few cycles. Using iron pyrite, the researchers have found that the improved performance withstands many more charge and discharge cycles than with other materials. "The batteries of tomorrow that can charge in seconds and discharge in days will not just use nanotechnology, they will benefit from the development of new tools that will allow us to design nanostructures that can stand up to tens of thousands of cycles and possess energy storage capacities rivaling that of gasoline," says Assistant Professor of Mechanical Engineering Cary Pint.

General Motors will provide the Army with a fuel cell test vehicle. GM's product development boss Mark Reuss says that the company will build a "fuel cell reconnaissance vehicle" for the US Army Tank Automotive Research, Development and Engineering Center. "It will show the unique advantages our proven fuel cell technology can offer in an all-terrain tactical application," says Reuss. For the Army, fuel cell vehicles have the advantage of being quieter, offer high torque at low speeds, can generate electricity in the field, and hydrogen fuel weighs less than gasoline or diesel.

Ryder will provide renewable natural gas at its stations in Orange and Fontana, California. The company announced it will switch to Redeem biomethane made by Clean Energy Fuels, and will make it available in both compressed (CNG) and liquefied (LNG) forms for individual and public fleet vehicles. Ryder expects to reduce greenhouse gas emissions by about 6,300 metric tons per year with the switch. Read more at Green Car Congress, or in the press release below.
Clean Energy to provide Redeem™ renewable fuel, fuel station Maintenance & Services at Ryder's Orange and Fontana stations
MIAMI & NEWPORT BEACH, Calif.--(BUSINESS WIRE)--Ryder System, Inc. (NYSE: R) and Clean Energy Fuels Corp. (NASDAQ: CLNE) today announced an agreement for Ryder to take the bold step in switching the fuel at their stations in Orange and Fontana, CA, to Clean Energy's Redeem™ renewable natural gas (RNG), the cleanest fuel commercially available today. The fuel at the two stations will be available in both compressed natural gas (CNG) and liquefied natural gas (LNG) to individual and public fleet vehicles.
"Our decision to use 100% renewable natural gas is based upon our ongoing commitment to ensuring we are delivering solutions that help our customers reduce greenhouse gas emissions," said Scott Perry, vice president of Supply Management and Global Fuel Products, Ryder System, Inc. "With Redeem™ we achieve that with a 100% renewable fuel."
By making the switch to Redeem™, Ryder is expected to reduce greenhouse gas emissions by approximately 6,300 metric tons per year using current fuel volumes. This would be the equivalent of removing approximately 1,319 passenger cars from the road annually.
Ryder is the leader in natural gas vehicle solutions for the commercial transportation industry, with more than 40 million miles of experience, 18 strategic natural gas vehicle maintenance markets, and more than 4,000 natural gas vehicle trained personnel. Ryder has been the pioneer in transitioning their fleets to cleaner fuels and today operates both CNG and LNG vehicles supported by 34 Clean Energy locations.
As part of the fuel agreement, Clean Energy also will be providing fuel station maintenance services at Ryder's natural gas fueling stations in Fontana and Orange, CA. Ryder has a long history of innovation and customer service and is the first and only truck leasing and logistics company to have on-site CNG and LNG fuels available to the public. Ryder selected Clean Energy for its experience maintaining its own network of public access stations as well the "behind the fence" fueling operations at over 34 customer stations.
"After launching Redeem™ as a commercial fuel just two short years ago, Clean Energy is on track to deliver over 40 million gallons this year," said Harrison Clay, president of Clean Energy Renewables. "Ryder's leadership to provide Redeem™ at their two stations in southern California will now expand the benefits of the cleanest fuel to Ryder commercial customers' fleets operating hundreds of additional heavy duty trucks and other vehicles."
Redeem™ by Clean Energy is a renewable natural gas vehicle fuel, often referred to as biomethane. It is derived from biogenic methane or biogas, which is methane that is naturally generated by the decomposition of organic waste. The methane gas is then processed, purified and sent into the interstate natural gas pipeline and made available exclusively to Clean Energy customers. Redeem™ biomethane vehicle fuel is procured from over 15 biomethane production facilities, including two owned and operated by Clean Energy. Clean Energy is on track to deliver 40 million gallons of Redeem™ in 2015. For a short video to understand how Redeem™ is made, visit https://www.youtube.com/watch?v=3VapWtJGVEw.
