Kot jst vem je (trenutno) problem v:
-pridobivanju vodika (potrebne velike kolicine energije)
-majhni gostoti vodika (posledicno manjsi dosegi avtomobilov)
-ceni
Najvecji problem je pomoje dejansko politika in nezanimanje folka. Ce bi res hotli bi po moje zmogli, sam kaj ko se ne "splaca"
“The advantages of hydrogen praised by journalists (non-toxic, burns to water, abundance of hydrogen in the Universe, etc.) are misleading, because the production of hydrogen depends on the availability of energy and water, both of which are increasingly rare and may become political issues, as much as oil and natural gas are today,” says Bossel.
“There is a lot of money in the field now,” he continues. “I think that it was a mistake to start with a ‘Presidential Initiative’ rather with a thorough analysis like this one. Huge sums of money were committed too soon, and now even good scientists prostitute themselves to obtain research money for their students or laboratories—otherwise, they risk being fired. But the laws of physics are eternal and cannot be changed with additional research, venture capital or majority votes.”
Even though many scientists, including Bossel, predict that the technology to establish a hydrogen economy is within reach, its implementation will never make economic sense, Bossel argues.
“In the market place, hydrogen would have to compete with its own source of energy, i.e. with ("green") electricity from the grid,” he says. “For this reason, creating a new energy carrier is a no-win solution. We have to solve an energy problem not an energy carrier problem."

The Specialty Equipment Market Association (SEMA) Show in Las Vegas is the site where hotrodders, sport compact tuners and other go-fast types get together. But a new zero-emission, all-electric sports utility truck from Phoenix Motorcars grabbed substantial attention at the show, especially since it was unveiled in an event hosted by the actor and environmental activist Ed Begley Jr.
Powered by the Altairnano NanoSafe battery pack, the truck targets the fleet vehicle market. It is said to exceed all specifications of California Air Resources Board for a Type III zeroemission vehicle (ZEV). The SUV has a reported driving range of 130 miles; it can be recharged in less than 10 minutes and the battery pack has a life of 12 years or more. Depending upon electric rates, the cost to recharge the battery pack is less than $3. While you might expect an all-electric vehicle to be no more than a glorified golf cart, the Phoenix sport utility truck can cruise on the freeway at up to 95 mph while carrying five passengers and a full payload.
A low-cost maintenance schedule is another advantage of the pure electric truck. It is slated to be introduced late this year in two configurations, one with a range of 130 miles and the other 250 miles. Both configurations can be recharged in less than 10 minutes.
Officials from Phoenix Motorcars and Altairnano, the manufacturer of the NanoSafe battery system, were on hand during the brisk, unscripted press conference. Dan Reigert of Phoenix said a production run of 500 units is planned for 2007. Since the vehicle is based on a Korean-made chassis, the technology may be transferred to Korea for expanded production. The goals include 6,000 units in 2008 followed by 20,000 in 2009 and 100,000 in 2010. Besides the truck, Phoenix wants to develop an SUV.
