NREL study finds high-pressure hydrogen pipeline system could potentially make hydrogen cost-competitive with gasoline

Green Car Congress

About half of the levelized cost of retail station hydrogen can be attributed to hydrogen delivery, compression, and dispensing costs. Department of Energy (DOE) estimates that a dispensed cost of about $7/kg must be achieved to make FCEVs competitive with gasoline internal combustion engine vehicles in early FCEV markets.

Driving Dystopia: More Companies Found Covertly Sharing Driving Data, Raising Insurance Rates

The Truth About Cars

With corporate media finally aware of the perils of connected vehicles, we’ve seen a rash of articles exploring how insurance rates have spiked due to automakers sharing user data. But the concept was floated as a way to lower individual rates by remotely tracking good driving behaviors.

Retrofitting three-wheeler to electric 

Electric Vehicles India

With an increase in shared mobility such as metros, monorails, and BRT systems, last-mile connectivity has already acquired the importance of never before. For last-mile connectivity is three-wheelers which are more suitable. Cost-effective if it is available at about 50-60% price less than buying new autorickshaws. Advantages.

Car Crash Prevention System Wins Student $10,000 IEEE Scholarship

Cars That Think

He came up with a mechanical barrier system that attaches to the hood and connects to the car's electronic control unit. The concept of a 3D-printed 3D printer was a theory before Minnick began his project three years ago. He says that the unsustainable cost of building spaceships is what prevents long-term space travel.

OSU hybrid “solar battery” uses photo-assisted charging to improve performance of Li-air batteries; “negative overpotential”

Green Car Congress

The basic concept of the integrated solar battery is to use the contribution of the photovoltage to reduce greatly the charging overpotential caused by the difficulty in efficiently electrochemically decomposing lithium peroxide (Li 2 O 2 ), the discharge product formed on the oxygen electrode. Their hybrid design uses only three.

NREL sets new world efficiency record for solar hydrogen production: 16.2%

Green Car Congress

The record-setting PEC cell represents a significant change from the concept device Turner developed at NREL in the 1990s. Holes in the E VB in GaInP recombine (yellow dot) with electrons in the E CB in GaInAs at the transparent tunnel junction that connects the GaInP photovoltage (Vph1) and GaInAs photovoltage (Vph2) in series.
