Toyota’s Hydrogen vs. Tesla’s Which Car Will Win?

combustion engine, or ICE, have been around for a Unfortunately, gasoline consumption is good for the environment, nor cheap. driving automakers to search for the big technology to power tomorrow’s — and fueling a fight for the between two competing technologies.

Car like  Toyota Motors  ( TM ) ,  Hyundai Motors   ( NASDAQOTH: ). and  Honda Motor   ( HMC )  are betting on hydrogen cells. But Tesla Motors   ( TSLA ) is going all in on  lithium-ion, or batteries. The victor in this could determine what our vehicles for decades to come.

Believe it or not, electric have been around the 19 th century. But they declined in due to their limited range, and to gasoline-powered vehicles effectively them into oblivion. however, they’re making a There are currently a number of electric vehicles, or BEVs, and they absolutely cut out the cost of and reduce our dependency of foreign That’s the good news.

Unfortunately, there are a number of big with BEVs. Unless willing to shell-out for Tesla’s S, range is still a significant And even if you do opt for the Model S, the battery can 20 minutes just to reach 50% compared to a few minutes’ refueling for ICE The National Academy of Sciences, or lists both of these as significant deterrents to mass-market for BEVs.

But those aren’t the problems with batteries. the battery of choice for most is expensive. And even though the has dropped significantly, even optimistic conditions, by 2030 the is not expected to get below $200-$250/kWh. For an battery with 300 miles of this translates to $17,000 for the alone .

By 2050, under conditions, the NAS stated : The practical limit of Li-ion cells is about $80/kWh, and the corresponding cost would be $150-$160/kWh. still $12,750-$13,600 just for the  Further, the NAS said: The present auto has a range of about 300 on a tank of gasoline. Very few BEVs will greatly 100 miles for the next several In other words, the affordable range BEV won’t be arriving soon.

Plus, while li-ion sound green, as I previously BEVs are only as green as charges the battery. Consequently, with estimates from to grid power in 2035, a BEV on the U.S. average electricity mix will produce anywhere around half to 80% of the greenhouse gas of a gasoline-powered vehicle. (That’s slightly better than engines, which are expected to 85% of a gasoline engine’s emissions.)

manufacturing one battery for a BEV releases 10,000 and 40,000 pounds of dioxide into the atmosphere. To put into perspective, Climate estimated that manufacturing a gas for a 3200 lb car would create 1,486 pounds of CO2 . according to Climate Central, the way to recoup a battery’s carbon relative to a gas-powered car would be to charge it only with carbon-free energy, and then the car it powered for tens to hundreds of of miles.

But wait — the picture worse. The most popular way to get the for li-ion batteries is through brines — underground of water that have abundant lithium and other According to the European Commission on for Environmental Policy, pumping and these salar brines a significant environmental, health, and impact to the places where is located.

In short, while cars emit fewer gases than ICE vehicles, the isn’t nearly as green as it

Hydrogen fuel cells

hydrogen. Hydrogen fuel cell or FCVs, aren’t yet available, but Toyota and Honda are showcasing concept fuel cell at this years Tokyo show, with plans to around 2015. Furthermore, has already developed a production electric vehicle, the iX35, and delivered its first line-produced to Copenhagen, Denmark. Plus, said it plans to release ix35s by 2015, and 10,000 shortly after. More here’s why auto giants are for hydrogen.

hydrogen is the most abundant in the universe, so the use of it as a fuel eliminates our on foreign oil. Second, can be refueled in minutes, and have a range similar to an ICE vehicle. importantly, the price for fuel has decreased dramatically, thanks in no part to their reduced use of

According to the NAS, Detailed of current costs and expected advances that are already demonstration have resulted in a cell system cost of $39/kW for a high-volume FCEV introduction in 2015.

Even By 2030, the Department of Energy, in with NAS, estimates the price for an average FCV will be $34,181, before government That’s in comparison to the price for a which in 2030 is $34,979 .

the FCV owner will have to pay for but the total ownership cost per is $0.358, just slightly the $0.355 cost for battery-powered More pointedly, when the greenhouse gas emissions from produced from natural gas are to be 45% to 60% of a gasoline-powered car by 2035 — overall than the GHG emissions charging a BEV.

No, it’s not the Hindenburg on wheels

people think about they envision the Hindenburg Luckily, new reports show the Hindenburg actually caught due to its gasbag’s fabric being with iron oxide, acetate and aluminum powder, a highly flammable propellant .

In hydrogen is no more dangerous gas. According to the IEEE:

A key is that hydrogen is 14.4 lighter than air, at 20 m/s (45 mph), and thus quickly and disperses. Thus it is difficult to hydrogen for a hazardous scenario. has a diffusivity in air of 3.8 times faster and 6 times faster than gas, thus rapidly upwards if accidentally released. combustion produces water and this, together with the of carbon, means that a of the radiant heat is produced to a hydrocarbon fire, thus the of secondary fires is greatly

In other words, hydrogen is for use as a fuel.

What to watch

FCVs are and really, the only significant to entry is the current lack of infrastructure. However, countries Europe and Asia are building the equipment — as is California. importantly, that same of infrastructure also applies to In addition, FCVs have advantages over BEVs.
