Sandia study finds more California gas stations could provide H2 than previously thought; NFPA 2 code

Green Car Congress

A study by researchers at Sandia National Laboratories concludes that a number of existing gas stations in California can safely store and dispense hydrogen, suggesting a broader network of hydrogen fueling stations may be within reach. There are 9,710 retail gasoline stations in California.

Up close and personal with Volkswagen’s e-Golf carbon offset project: Garcia River Forest

Green Car Congress

Trees are natural carbon sinks; they absorb carbon dioxide by photosynthesis, some of which is stored as carbon compounds in the wood—both during growth and even after harvesting, in the form of some wood products. Underground, forest soils and root structures store even more carbon. Calculating stored carbon; “additionality”.

US DOE Issues Request for Information on Hydrogen and Fuel Cell Market Development; Reports to Congress on Program

Green Car Congress

Hydrogen produced by water electrolysis has the potential to be a useful means of storing excess electricity generated using wind, solar, and other intermittent renewable energy. New materials have provided more than 50% improvement in storage capacity since 2004, with some materials achieving nearly 10% material-based capacity by weight.

BMW Outlines Intelligent Heat Management Applications for Reducing Fuel Consumption and CO2; New Thermoelectric Generator Unit Integrated with EGR

Green Car Congress

A great deal of thermal energy is generated while driving and is available after coming to a stop—energy stored in components such as the engine and transmission. The original TEG development was a stand-alone underfloor solution developed since 2004 also as part of a project promoted by the US Department of Energy.
