It’s amusing to reduce the development of next-generation electric- or hydrogen-powered cars to a binary paper-versus-plastic decision, but the companies making these cars and the infrastructure to support them are hoping there will be room for both. Hydrogen cars, in particular, have had a bumpy road thus far–the Obama administration has been at odds with Congress over whether to fund hydrogen fuel-cell research. Meanwhile, the first commercial models are not expected to hit the road until 2015, a few years after their hybrid and all-electric counterparts . [More]

DETROIT, January 11, 2010—Toyota Motor Sales (TMS), U.S.A, Inc., today unveiled the FT-CH dedicated hybrid concept at the North American International Auto Show (NAIAS) in Detroit. The FT-CH is a concept that would address Toyota’s stated strategy to offer a wider variety of conventional hybrid choices to its customers, as it begins to introduce plug-in hybrids (PHVs) and battery electrics (BEVs) in model year 2012, and hydrogen fuel cell vehicles (FCHVs) in 2015 in global markets.

[...] One of the big issues facing hydrogen is just where we’re supposed to fill the cars that might run on the stuff. A Connecticut company is answering that question on the East Coast with plans for a “hydrogen highway” that will extend from Portland, Maine, to southern Florida. California historically has been a hotbed of hydrogen research and development, but SunHydro wants to put the East Coast on the H2 map with 11 solar refueling stations. The self-contained stations use electrolysis technology from Proton Energy that takes electricity generated from solar power and splits water into hydrogen and oxygen. The process results in considerably fewer emissions than the traditional methods of shipping hydrogen to fueling stations by truck or reforming it from natural gas. [...] Demand for automobiles is rising worldwide. So is concern about greenhouse gas emissions. In response, scientists and engineers are working diligently to perfect new power plants for future vehicles, including battery and hydrogen fuel-cell electric cars. Although these and other alternatives show great promise for the long term, perhaps the single greatest way to reduce fossil-fuel consumption in the near term is to further improve today’s dominant transportation power plant: the gasoline internal-combustion (IC) engine. Fortunately, efficiency can be raised in a number of ways, notably, better control over the air-fuel mixture entering the combustion chamber, over the way gasoline is ignited there, and over the mechanical systems that harness that energy. These can improve traditional automobiles as well as gasoline-electric hybrid models. [More]
This is one of those topics I’m just not sure what to think of… When the average person hears the term fuel cell, typically what comes to mind is something that mysteriously makes electricity from hydrogen. In reality the process isn’t all that mysterious—basically the hydrogen is split into its component parts (electrons and protons) and the protons are allowed to flow through the cell, but the electrons are forced to travel another path, which creates the current (and charges the battery or runs the motors or turns on the lights). Although the hydrogen fuel cell is the most common type of cell, you can make fuel cells that use many different things, including hydrocarbons and sugars. They all work on the same basic principal, but hydrogen fuel cells are considered superior because their only emission is water vapor and they produce lots of energy.
Welcome to another episode of “If college students can do it, why can’t the rest of the world figure it out too?”
An enterprising and organized group of undergraduate and graduate students at Rensselaer Polytechnic Institute have fitted an old sail boat with a spiffy set of hydrogen fuel cells and plan to run the boat from Manhattan to upstate New York later this month in a “green power” tour of sorts. I love it when college students do this kind of stuff. Seriously. If I could have stayed in college forever, I would have. Believe me, I tried.
