The cars are coming, where’s the hydrogen?
By Bill Mitchell, Vice President, Sales and Marketing
Nuvera Fuel Cells

Through 3 days of keynote addresses and meetings at the National Hydrogen Association meeting (including a ride and drive where we were allowed to put the Chevy Equinox fuel cell vehicle and BMW Hydrogen 7-series to the test on a small rally track), one of the overarching themes that started to emerge on the fuel cell vehicle front was: The cars are coming – where is the hydrogen?

NHA Panel 

On the first day, Paul Brubaker, Administrator of Research and Innovative Technology Administration for the U.S. Department of Transportation challenged all of us with a simple question: Why not?  That is, why not make the required investment in hydrogen and fuel cells to move our country away from fossil fuels.  In the 1950’s, President Eisenhower signed the Federal Highway Act that resulted in our interstate highway system.  In the 1960’s, President Kennedy enabled research to put a man on the moon with the Apollo program.  In the words of Mr. Brubaker, both of these programs were expensive at the time, but in retrospect, have forever changed our society for the better.  Investment in hydrogen and fuel cells will be viewed similarly in the future.

On the second day, Dr. Mary Nichols, the Chairwoman of the California Air Resources Board discussed a recent decision at CARB that will mandate fuel cell vehicles, battery electric vehicles, and plug-in hybrids.  According to CARB, the mandate will ensure that in the 2012 to 2014 timeframe, that a total fleet of 7,500 fuel cell vehicles (5,357 if OEM’s can make the cars travel at least 300 miles on a tank of hydrogen) will be running around the streets.  This will be augmented by no less than 58,333 plug-in hybrids.  During her talk, she indicated that CARB is still studying how to “mandate” a hydrogen infrastructure to support the fuel cell vehicle rollout.

Fast-forward to today, and a few speeches stood out as a harbinger of things to come.  First, McKinley Addy of the California Energy Commission (CEC)  made a special announcement that the CEC has approved a budget of $120 Million per year for an 8 year period (total of $ 1 Billion) to help foster the commercialization and adoption of alternative fuels and clean energy technologies, including fuel cell vehicles and hydrogen refilling stations.

 Larry Burns VP of R and D at GM

Second, Larry Burns, the Vice President of R&D and Strategic Planning at General Motors discussed GM’s perspective on hydrogen. Mr. Burns started by stating that the potential societal and consumer benefits of fuel cell technology are clear and compelling, and that no other technology offers this exciting potential.  In fact, he stated that GM has not uncovered a single issue yet to suggest that mass volume of fuel cell vehicles cannot ultimately be attained.  With that being the good news, Mr. Burns continued his talk by reaching out and challenging the energy providers stating that what is urgently needed is sufficient investment by energy providers to assure auto companies that the required hydrogen infrastructure will be in place when we deploy our next generation of fuel cell electric vehicles. In the view of GM, for the equivalent cost of 2 tanks of gasoline for every car in the U.S., we could deploy a hydrogen infrastructure that would put hydrogen refilling stations within 2 miles of 70% of our population. In closing his talk, he stated that together, we must act rather than debate, create the future rather than try to predict it, and solve the challenges we face now rather than handing these off to future generations.

As the meeting draws to a close, I feel enthusiastic about the future of fuel cell vehicles and hydrogen.  I never did get to see Governor Schwarzenegger to deliver the fuel cells personally, but there is always next time.

The Pininfarina Sintesi doesn’t have 700 horses, but you won’t miss them!

Pininfarina Sintesi Cutaway

Let me start by saying that it’s great fun to work on a project that gets noticed. From the start, we knew that the opportunity to design the fuel cell powertrain for Pininfarina’s Sintesi concept car would be a great showcase for our technology – a chance to get the word out about what fuel cells can do in a car that’s made for them. Then, a few weeks before the unveiling of the car at the Geneva Motor Show, the word hit the blogosphere:

“The fuel cells for the electric-hydrogen hybrid, rumored to be worth 700 horsepower all told, are being distributed all around the body…”
Autoblog Feb 7th 2008

 

“…it will be an electric-hydrogen hybrid system and not a typical one at that (not all concept cars need to generate 700 hp the way the Sintesi apparently does)…” AutoblogGreen Feb 7th 2008

 

“The advanced drivetrain was a joint-effort between Pininfarina and UK firm Nuvera Fuel Cells. Its makers claim the Sintesi develops a combined output of 700hp…”
Motor Authority March 3rd 2008

 

…and many more…

 

The word was getting out all right – it just happened to be inaccurate! Aside from the fact that we’re a US (not UK) company, the engine that we were busy designing didn’t have 700 horsepower! I still have no idea how that number got into all those stories. While the Sintesi may only have 240 horses under the hood (or actually, next to the wheels…there is no hood), it still drives like a high performance car.

 

While most people think of power as the defining characteristic of an engine, the power isn’t directly what makes the car accelerate - the torque on the wheels is responsible for that. Most combustion engines are quite good at this…at high speeds. IC engine cars rely on the transmission gearing to convert the engine shaft torque at a few thousand RPM to axle torque at a few hundred RPM. In the Sintesi, we have a completely different situation. The electric motors are right in the wheels - no transmission required - and these motors produce their highest torque at the lowest speeds. For the driver, this means that that from a standstill the fuel cell engine can funnel every bit of its power right into the wheels - providing a push-you-back-in-your-seat acceleration.

 

The end result? The Sintesi, with “only” 240 hp (110 from the fuel cells and 130 from the batteries), can accelerate from 0 - 60 mph in 6.4 seconds. That’s pretty fast. Top speed on the fuel cell power alone is 119 mph; with battery boost the car can reach 155 mph. Not bad for a car that also gets 50 miles per gallon and seats four!

Pininfarina Brings their Award Winning Design to the Fuel Cell

Pininfarina, the famed Italian automotive designer, revealed its latest concept car at the Geneva Motor Show today. The revolutionary new car is called the Sintesi, and it features Nuvera’s new Quadrivium drive, which combines the high efficiency of fuel cells with the ability to operate on both conventional and biofuels.

When Pininfarina approached us with the ambitious challenge of making a high performance power train using ecologically benign technology, Nuvera engineers changed direction away from conventional technologies and embraced a radical new fuel cell concept. The result was four distributed wheel power modules, which allowed the car itself to be designed around the passengers, rather than the power train. The Sintesi brings together the cutting edge design approach of Pininfarina with our cutting edge technology, to provide a concept car as innovative in its look as it is in operation. What do you think of the new Sintesi?
