Startup commercializing thermo-acoustic Stirling technology for combined heat and power for homes

Green Car Congress

is developing the Thermo Acoustic Power Stick (TAPS)—a micro-combined heat and power (ยต-CHP) system for home use that converts gas into electricity and provides for domestic water and space heating. The linear alternator produces the electricity. A prospect to be explored is a thermo-acoustic design. Resources.

Small-displacement two-stroke H2 engine could address performance and emissions cost-effectively for recreational market; potential for Asian motor vehicle fleet

Green Car Congress

The two-stroke engine has been favored for small recreational vehicles because of its high power density, low cost and simple, lightweight design, Oh said. The lost available energy also results in poor off-design point fuel efficiency. A presently voluntary 5 Star designation would further halve that limit to 2.5

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. The study determined that 14 of the 70 gas stations—i.e.,

EPA trends report sees record levels of average new vehicle fuel economy and CO2 emissions for MY 2012; role of new gasoline vehicle technologies

Green Car Congress

EPA projects advanced transmissions (6+ speeds and CVTs), gasoline direct injection (GDI) systems, and turbocharged engines will be installed on at least 15% of all MY 2013 vehicles. Based on the final Trends data through MY 2012, CO 2 emissions have decreased by 85 g/mi, or 18%, since MY 2004, and fuel economy has increased by 4.3

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. Biogas, including anaerobic digester gas, can be reformed to produce hydrogen and used in a fuel cell to produce significant amounts of electricity and heat.
