Hydrogen Highways

Timothy Lipman

The state of California has for many years been at the vanguard of environmental and energy policies, creating strict standards that have afterwards been adopted by other states. Today is no different. Despite a severe budget crunch, California Governor Arnold Schwarzenegger has recommitted the state to a variety of clean energy goals, including deregulation and liberalization of electricity markets, increased energy efficiency in new and retrofit state buildings, and reductions in greenhouse gas emissions. The state has also outlined a major solar-power initiative and a Renewable Portfolio Standard that sets goals for producing electricity from renewable sources. And in pursuit of the elusive zero-emission vehicle — the ZEV — the governor has called for California to take a leading role in advancing the commercialization of hydrogen-powered vehicles with the “California Hydrogen Highway Network.”

Power from the Fuel Cell

Timothy Lipman

Automobiles are often criticized for consuming so much petroleum. While much has been done in the past twenty years to make vehicles pollute less, the growing popularity of larger vehicles is making vehicles consume more energy. However, emerging technologies suggest that new generations of vehicles can be built that will be much more efficient than those on the roads today. Furthermore, the prospect of future vehicles incorporating electric drive systems means they may be able to integrate with the electricity grid in a novel way: they may be able to supply electricity to the grid, thereby eliminating the need to build new power plants in some areas.
