The State of Hydrogen Research

Hydrogen fuel cell research is in the midst of a raging debate. There are great challenges to the electric-vehicle infrastructure and most people will overlook the challenges. Many people do not have access to plug-in garages and it would take billions to upgrade the smart grid to coupe with the demand. On the other hand, the cost of mass-producing fuel cells is going down. The biggest issue with electric vehicles is the fact that people lose interest in things that do not produce results quickly.

Street Car Reborn with Hydrogen Fuel Cell

Engineers and transit planners are turning to streetcars for hydrogen propulsion. Traditional trolley cars have drawn power from catenaries, overhead electric supply lines running along city streets. Hydrogen powered streetcars will eliminate the wires, which may help make streetcars more acceptable.
