Toyota & Mercedes are Proving that Hydrogen FC and Battery Electric are Perfect Compliments

Thursday, March 19th, 2009

I have written a couple of times about the debate between hydrogen fuel cell vehicles and battery electric (here and here). Proponents of each are busy slandering the other. Meanwhile, Toyota and Mercedes are quietly proving that the two technologies are perfect compliments.

Fuel Cell Hybrid Vehicles (FCHV)

Toyota is the world wide leader in hybrid vehicles (thanks to the Prius). They are applying what they know about gasoline-electric hybrids to make FCHVs. Take a look at this diagram:

Essentially, they have  replaced the gasoline engine from their hybrid drive-train with a hydrogen fuel cell. This allows for a zero emissions vehicle that has a range of over 500 miles and refuels in roughly the same amount of time it takes you and me to fill up with gasoline.

Mercedes is doing the same thing only with a bus.

But Battery Electric is 3x More Efficient Than Hydrogen!

I know, I know, but remember how Toyota is developing a plug-in version of the Prius? It’s a Prius that you charge at home, then drive 30-40 miles on 100% battery power. Doesn’t it seem reasonable that they will apply the same technology to the FCHV? Imagine! All of your quick drives use only efficient battery power charged from the grid. When you need longer range, however, the hydrogen fuel cell kicks in and provides it for you.

I think this is the most promising alternative fuel arrangement that I have seen. It has all the convenience of a hydrogen fuel cell vehicle (or gasoline for that matter) plus the efficiency of a battery electric vehicle.

Hydrogen Fuel Cell vs Battery Electric (the debate simplified)

Thursday, March 12th, 2009

In the world of alternative fuel vehicles there is a vicious debate over hydrogen fuel cell vs battery electric vehicles. At times it seems no less heated than John McCain vs Barack Obama (here is a small example).

Who Cares?

I strongly believe that one or both of these technologies is nearing a tipping point—a point where the technology will spread like a virus through the entire automotive industry. It will be a boom that reshapes the automotive industry similarly to the way cell-phones reshaped telecommunication. I certainly think it is worth understanding the pros, cons, and potential of each technology.

The Debate Simplified

Hydrogen and battery electric vehicles each produce great driving, zero emissions, electric vehicles. There are many arguments for and against each, but it is necessary to filter out all of the brainless rhetoric to get to the bottom of the debate.  I say brainless because there are a lot of stupid arguments about how one technology or the other is not affordable. Go figure! How many people could afford a cell-phone in 1989? Another argument that is far less stupid, but equally insignificant is that of infrastructure. Infrastructure ALWAYS follows successful products (notice how 3G technology is only available in select cities right now—if the technology proves successful, the infrastructure for it will quickly spread).

Once you get past all that, the debate is quite simple:

  • Proponents of Hydrogen: Fuel cell vehicles have longer driving range, shorter refuel time, and require no major lifestyle changes when compared to today’s gasoline vehicles. Battery electrics, on the other hand, are more limited in range, not as quick to refuel, and are a bit different to own than today’s vehicles—mostly because you have to plan time to charge them.
  • Proponents of Battery Electric: It is 3 times more efficient to produce electricity and store it in a battery than it is to convert the energy to hydrogen then back to electricity again to power the car.

Searching for the Holy Grail

Both technologies are desperately searching for ways to overcome their shortcomings: hydrogen needs to improve its efficiency (here) while batteries need to be faster charging and have longer ranges (here and here).

Can They Compliment Each Other?

Toyota and Mercedes both seem to be proving that hydrogen fuel cells are perfect compliments to batteries. In fact, they even seem to solve each other’s weaknesses. Maybe the whole debate is a mute point? More on that soon.

Michelin Reinvented the Wheel

Thursday, February 5th, 2009

Imagine a car where the motor, transmission, drivelines exhaust, suspension, and brakes are all inside the wheels. Okay, that’s impossible. But what if there were no need for a transmission, drivelines, and exhaust? Could you put the motor and the suspension inside the wheel? Michelin did:

The entire unit bolts to the car and needs nothing but a brake line and electric connector to enable all its components.

This invention has HUGE potential! It could be used on EVs, Hydrogen Fuel Cell vehicles, or even hybrids (at least a Chevy Volt type hybrid). It could be used in two or four-wheel-drive, and front or rear-wheel-drive configurations. Car designs could change drastically because the usual space set aside for drive train components could be used for other things.

Here is one prototype application (notice how the computer controlled suspension allows it to lean into turns):

The first production car to use the technology will be the 2010 Heuliez WILL.

I wonder if changing a tire will still be simple. If not, I suppose there is always AAA to do it for you. :)

BBC’s Top Gear: “The Honda Hydrogen FCX Clarity is the Most Important Car in 100 Years.”

Wednesday, December 17th, 2008

With the debate still raging over electric cars vs. hydrogen cars, BBC’s Top Gear recently drove the Tesla Roadster followed later by the Honda FCX Clarity. They proclaimed Honda’s FCX Clarity “the most important car in 100 years.” They interviewed Jay Leno in the same program. He calls it “the savior of cars.”

I don’t believe that hydrogen vehicles are still years and years away. See for yourself:

How To Develop The Hydrogen Infrastructure

Thursday, December 4th, 2008

For ten years I have been told that a hydrogen infrastructure is the main thing keeping us from hydrogen fuel-cell vehicles. The problem is framed as a Chicken and Egg type dilemma. Should the cars come before the infrastructure, or vice versa? After studying how other infrastructures were developed, I am convinced that a hydrogen infrastructure will only be developed if it is preceded by the release of hydrogen fuel-cell cars.

History Supports This Theory

When America transitioned from using coal to natural gas for heating homes, a new infrastructure was needed. Everything from storage, pipelines, delivery trucks, and dispenser systems were needed to get natural gas to its users (who would want to mass produce natural gas furnaces without an infrastructure?). The transition didn’t happen over night. Natural gas furnaces started out as a luxury item that only the rich could afford—they were clean, convenient, and environmentally friendly. The demand for natural gas from the rich drove the development of better infrastructure. The new infrastructure, in turn, made natural gas more available and more affordable. Gradually more and more people could afford the switch. In fact, natural gas eventually became less expensive than coal. The transition from coal to natural gas happened simultaneous to the development of the infrastructure, but it was led by people’s demand for natural gas furnaces (the end product).

Many other industries underwent similar transitions:

  • Wood to Coal
  • Telegraph to Telephone
  • Candles to Kerosene Lamps
  • Horse and Buggy to Automobile
  • Kerosene Lamps to Electricity
  • Dial-Up to Broadband Internet

Other industries were started from scratch rather than transitioning from a previous industry. They still required a new infrastructure:

  • Radio
  • Television
  • Cell Phones

It’s obvious the need for new infrastructure is nothing new. All of these products started out as expensive luxury items with little or no infrastructure. Their infrastructures developed gradually (not to be confused with slowly). This development happened simultaneous to the products being adopted. And because all of these products were better/more affordable than their predecessors, they all developed into the industry standard. Hydrogen could do the same.

A Lesson From the Automotive Industry

Hydrogen fuel-cell cars are not the first innovation to come out of the automotive industry. New innovations are a regular occurrence (IE: air conditioning, power windows & locks, power steering, and countless others). The manufacturers almost always begin by releasing these new features ONLY on their high-end models. The features that are really worthwhile quickly trickle down the model lines until they are available even on economy cars. The features that are less worthwhile either fade out or stay limited to the high end models. Why should fuel-cells be any different?

My Suggestion

Honda, Toyota, GM, Hyundai, and any other manufacturer who has the technology and ability should release a high-end, luxurious, expensive fuel-cell car on a limited basis. In fact, these cars should be released under the companies’ premium badges (IE: Acura, Lexus, Cadillac, etc.) The release should be limited to densely populated areas where a hydrogen fueling station already exists (IE: Los Angeles, San Fransisco, DC, etc.) These cars should be loaded with expensive, organic/recycled materials. They should be designed to appeal to movie stars, politicians, and athletes—anyone who wants to make a flashy statement about their status and the environment.

Kudos to Honda

Honda is already doing a form of what I’m suggesting. They are leasing their FCX Clarity for $600/mo. to a limited number of people in the Los Angeles area. I’m certain that a few new hydrogen dispensing stations will pop up as a result. What a great way to get the ball rolling!

What NOT To Do

I hear environmentalists, auto manufacturers, and hydrogen advocates all calling for the government to take the initiative and build a hydrogen infrastructure. The idea is that if an infrastructure were to be built in advance, the auto manufacturers could finally release their fuel-cell vehicles and go straight into mass production.

I’ve made it pretty clear that I hate the idea of asking the government take care of it. Not only would it undermine freedom, but it would be a huge project wrought with waste and inefficiency. It is simply impossible for Washington DC bureaucrats to predict where and how many fueling stations should be built. Some areas would suffer shortages while others would have a surplus that could only be supported by forcing the tax payers to subsidize it.

It is essential that we trust in the free market and the law of supply and demand. It’s the only way for the infrastructure to grow in the right places, at the right time, at the right speed.

Conclusion

If auto manufacturers release their fuel-cell vehicles as high-end, luxury cars; then environmental advocates with plenty of money will be able to purchase the cars. This will send a signal to service station owners and hydrogen distributors who will in turn build up their hydrogen distribution infrastructure.

As hydrogen becomes more available, it will get less expensive. As the price goes down, demand for it will go up. With the increased demand, the auto manufacturers will be able to increase their quantity and lower their prices. The transition to hydrogen will be gradual but not necessarily slow.

Watch out for Hyundai

Thursday, October 30th, 2008

I occasionally make predictions about the automotive industry. Some happen, others don’t. I’ll tell you about a couple of my past predictions in upcoming posts.

For now, I want to make a prediction: we are 10 years away from an automotive marketplace that views Hyundai in the same light as Honda and Toyota.

In the 1980s Toyota and Honda, despite gaining popularity, were viewed as cheap, small cars that were simply inferior. With the launch of Acura and Lexus, both companies were able to shed the cheap and small stereotype. Through a commitment to quality and reliability, the two companies took the idea of inferiority and turned it on its head. Today Toyota and Honda seem to be the benchmark by which everyone else measures price, performance, reliability, etc.

Let’s parallel the Honda/Toyota story to what’s happening at Hyundai. All through the 1990s Hyundai was the Korean car company that produced cheap, small cars that were simply inferior. Through a commitment to quality and reliability they have been able to offer America’s Best Warranty. I see Hyundai’s recent launch of the Genesis as a parallel to Toyota’s launch of Lexus or Honda’s launch of Acura. Hyundai is proving that it can do more than cheap and small.

Hyundai Genesis

Hyundai Genesis

Further, Hyundai is the first car company (as far as I know) to announce mass production of hydrogen fuel cell vehicles. Being a first-mover in the hydrogen market could do for Hyundai what the Prius has done for Toyota.

What will it take?

  1. Hyundai will have to maintain quality and reliability. America’s Best Warranty will need to evolve and progress in order to stay the best.
  2. The Genesis needs to succeed. This car is key in shaping the public’s perception of Hyundai. Can it convince the masses that Hyundai is a contender in performance, styling, and comfort?
  3. Hyundai will need to keep its manufacturing costs at an industry low (company’s from China and India might have an advantage here, but Hyundai has a pretty big head-start to work with). Hyundai is currently able to produce the Genesis for far less than BMW, Mercedes, and even Toyota (I think).
  4. Finally, taking a full swing at the hydrogen market is a big gamble (which I applaud). No one knows how the hydrogen infrastructure will develop or how the public will take to hydrogen fuel cell vehicles. Hyundai’s willingness to roll the dice could have HUGE payoffs, but like all big gambles it could backfire.

My perception of Hyundai is rapidly changing. What do you think?

Build a Hydrogen Infrastructure Without Government Intervention

Friday, October 10th, 2008

I’ve been following the gradual developments of hydrogen powered cars for quite a few years. Although very promising, the technology still has some obstacles to overcome: production, transportation, storage, and distribution. While all these things need to improve, the greatest obstacle (by a long shot) is how to build the infrastructure for all this. It’s a classic chicken and egg dilemma. What car manufacture wants to develop and produce a car that depends on a non-existent infrastructure? What investor wants to finance an infrastructure to support cars that don’t exist?

Many people believe that government intervention is needed to give one or both sides (auto manufacturing and H2 infrastructure) a kick start. They think it will “get the ball rolling.” I say that idea is rubbish! The government would certainly get it wrong, but even more important, It’s none of their constitutional business! The framers of the constitution envisioned a government to protect rights, not to squander its people’s money on bad investments or hand-outs.

Greg Blencoe, CEO of Hydrogen Discoveries, presents an awesome idea. When purchasing a hydrogen powered car, the customer could have the option to buy into a co-op at their local hydrogen refueling station. They would essentially be buying a very small percentage of their local station (not unlike being a member of a credit union). This would get them “member prices” at their station and allow them a portion of quarterly profits. They could later sell to large companies who will eventually respond to the new market.

Not a bad idea. Do you think it would trigger innovation in hydrogen transportation and other areas?

Electric Cars vs. Hydrogen Fuel Cell Cars

Friday, August 29th, 2008

About ten years ago, as I was learning the field of automotive repair, I watched as GM toyed with the EV1 which was followed shortly by Toyota and Honda’s hybrids. I was fascinated by the changing automotive horizon. Some industry buzz inspired me to write my term paper on hydrogen fuel cell vehicles (I wish I still had a copy). Seeing EV1’s limitations and viewing hybrids as nothing more than a stepping stone, I was convinced that hydrogen would eventually replace gasoline as the world’s principle automotive fuel. While that could end up being the case, many believe that EVs have become an even better solution.

To understand the debate between electric cars vs. hydrogen fuel cell cars, it is important to understand that both cars are eventually driven by electric motors. The difference comes in the way the energy is stored. In electric cars the energy is stored in batteries. In hydrogen fuel cell cars the energy is stored in the from of hydrogen gas which is passed through a fuel cell to convert it to electricity.

So essentially, the real debate is between batteries and hydrogen fuel cells. Which one is more effective? That question isn’t easily answered because many factors such as cost, capacity, safety, reliability, accessibility, etc. all affect that decision. Ten years ago, I thought the answer was clear. What I never could have foreseen, though, was the surge in battery technology that would be brought on by the cell-phone craze. It’s left me believing that batteries might become better at storing energy than hydrogen (they’re not there yet).

Each of the two technologies have something going for them. EVs are benefiting from the already existent electrical infrastructure. Car makers aren’t as hesitant to build them knowing that customers will have a way to fuel them. Hydrogen, on the other hand, is simply better at storing large amounts of energy (Toyota’s Highlander Hybrid FCHV gets 80 miles per kg of hydrogen and has a driving range over 500 miles.)

Each technology also has a huge obstacle to overcome: Hydrogen has almost no infrastructure. Battery developers can’t seem to produce a battery that has all the characteristics they are looking for: safe, reliable, light-weight, small, affordable, long-lasting, powerful, etc. Many batteries fulfill a number of these requirements, but none have swept the table.

I don’t know if one will win out over the other, but both have huge potential. Wouldn’t you love to be a part of either industry when its obstacles are finally overcome?
