Let’s start with the electric vehicles: After Energy Secretary Steven Chu eliminated funding for hydrogen fuel from his budget, the Senate has reinstated it for the department’s 2010-2011 budget. Chu prefers straight-up battery electric vehicles for the future of greener transportation, but he says he’ll work with Congress on hydrogen fuel cell-powered electric vehicles.

Speaking of electric vehicles, you may have noticed that many of the EVs on the road today, especially neighborhood electric vehicles, have three wheels instead of four. Thanks to some heavy lobbying by Aptera and its three-wheeled brethren, Congress has extended research and development loans to manufacturers of safe, high-mileage vehicles, even if they are short a wheel.

Requirements for the loan:

• Vehicles must be fully enclosed
• Vehicles must meet all the same safety standards as conventional vehicles
• Vehicles must carry two adults
• Vehicles must average 75 mpg or equivalent

If you’ve been considering an alternative-fuel vehicle for your next car but were wondering where on earth to fill up, look no further than the U.S. Department of Energy. That’s right — the DoE has put together a handy web site where you can search for refueling stations for just about any kind of fuel except regular, ol’ gasoline:

• Biodiesel (B20 and above)
• Compressed Natural Gas
• Electric
• Ethanol (E85)
• Hydrogen
• Liquefied Natural Gas (LNG)
• Liquefied Petroleum Gas (Propane)

It should surprise no one that California leads the way in most types of alternative fuel stations. E85 is huge in the Midwest, which is another no-brainer, but biodiesel is big in Georgia and the Carolinas, which I did not know. Texas has hundreds of propane filling stations, as anyone who watches “King of the Hill” would probably guess.

There is a ton of information on the Alternative Fuels and Advanced Vehicles Data Center, and it will be a valuable resource as more alternative-fueled cars come to market in the next four years or so. Bookmark it now, folks, and tell all your friends who love green cars.

Kapp laid out Ford’s long-term strategy, from today to 2050. The company plans to migrate its advanced fuel-saving technologies, like hybrid systems and the new EcoBoost engine, across the product line by 2012, so at least a few Ford, Lincoln, and Mercury vehicles will get a little better gas mileage. By 2020, Kapp said Ford will fully implement current technology and begin to delve into more gasoline-electric hybrids, plug-in hybrids, and more. After that, the plan is to roll out hydrogen fuel-cell cars, biofuel-powered vehicles, and whatever other new technologies have developed by then.

Kapp was eager to point out the advantages of Ford’s new EcoBoost engine, which uses gasoline direct injection and turbocharging to raise fuel efficiency by as much as 20% and lower tailpipe emissions by as much as 15%. The physically smaller engine will be able to deliver the same or greater power as traditional Ford engines, and will be available first in the 2009 Lincoln MKS sedan.

Kapp pointed out that while Ford was not pursuing hydrogen-powered cars as quickly as Honda, nor was it chasing Chevy’s PHEV Volt with any conviction, it does have the first driveable hydrogen fuel-cell PHEV in the Edge HySeries. The fleet of 30 cars is still very much in the test stage, and Kapp noted that hydrogen fuel has “monumental infrastructure problems.”

When fielding questions about bringing clean diesel cars from Europe (answer: not any time soon), a fellow journalist mentioned that he ran his diesel-powered Ford truck on B99 every summer. Kapp nearly choked on his coffee when he heard that one of his trucks was being powered by 99% biodiesel a few months out of the year. I was surprised that he was surprised — he was in eco-conscious Portland, after all.

The tour is a partnership of the U.S. Department of Transportation, the California Fuel Cell Partnership, the U.S. Department of Energy, and the National Hydrogen Association. Each of the nine  manufacturers has one car in the 3,000-mile parade, except VW, which has two:

• BMW Hydrogen Series 7
• Daimler F Cell
• Chevy Equinox FCV
• Honda FCX Clarity
• Hyundai Tuscson FCV
• Kia Sportage FCV
• Nissan X-Trail FCV
• Toyota Highlander FCV
• Volkswagen Touran and Tiguan Hymotion

With only 61 operational hydrogen fueling stations in the entire country (28 of which are in California), you may wonder if they plan to drive cross-country on one tank of fuel. The answer is, “Sort of.” There are actually two giant tanks of hydrogen fuel following the fleet for topping up on the go.
