Maximizing Potential of Diesel and Gasoline for a Cleaner, More Efficient Engine

Diesel engines can be more than twice as fuel efficient as gasoline engines, but they also produce more pollution like particulate matter and nitrogen oxide. A team of researchers at Argonne are combining the efficiency of diesel with the cleanliness of gasoline.

Berkeley Lab researchers have designed a new anode -- a key component of lithium ion batteries -- made from a "tailored polymer" (pictured above at right in purple). It has a greater capacity to store energy since it can conduct electricity itself rather than using a polymer binder (such as PVDF, pictured above at left in brown) in the traditional method.
National Labs Leading Charge on Building Better Batteries

Teams at two of the Energy Department's laboratories are making headway on two projects that will enable building a new lithium battery that charges faster, lasts longer, runs more safely, and might also arrive on the market in the not-too-distant future. Learn more.

Fuel Station of the Future- Innovative Approach to Fuel Cell Technology Unveiled in California

Imagine pulling-up to a fuel station that supplies your car with clean, renewable fuel. Now imagine that, while you’re filling up, this same fuel-station just so happens to be providing power back to an entire industrial facility. Sound a little far-fetched? Perhaps, but, in a first-of-its kind milestone—a new fuel cell and hydrogen energy station in Fountain Valley, CA, is doing just that.
