A few weeks back I visited biodiesel enthusiast JP Patten at HUGR Systems in Orlando. JP has been pioneering the conversion of gasoline-fueled lawnmowers to biodiesel, with impressive results.
But JP is frustrated by the way the rest of the country fails to see the merits of diesel engines, which have for so long languished in the wake of our addiction to gasoline. As he points out, diesel engines are far more fuel efficient than their spark ignition rivals. For years they have been dismissed in the U.S. as being less environmentally friendly. So why is it then that Europe, which has far more stringent pollution controls than the U.S., is so rapidly transforming its transportation to diesel.
Part of the answer is that the U.S. and Europe measure vehicular pollution is different ways. In Europe the emphasis has always been on CO2 greenhouse gas emissions, while under U.S. clean air regulations all that counts is nitrogen oxides and sooty particulates.
U.S. emissions control systems, which filter
out the nitrogen oxides and soot, don't work well with U.S.
diesel fuel, because it has a much higher sulfur content
than Europe's. The debate is about to get more interesting after the EPA this year mandated diesel fuel to be produced with
lower sulfur content. But experts say that still won't make it comparable to Europe's fuel.
JP says he's worried that the scales are still too heavily tipped in favor of diesel. He says still Americans don't understand the value of diesel.
He cites a conversation with a friend, Dan, who told him “JP – we no longer need diesel fuel. It is an old technology and I don’t want to own a car that cannot be fueled. Soon there will be no more diesel fuel.”
JP's response was “What would happen if you awoke to an abrupt end of unleaded fuel?” Dan offered: “JP – the US as we know it would end – total gridlock – total chaos.”
So JP continued - “And what if diesel fuel were gone and there was plenty of unleaded?” Dan's answer: “No problem – we really don’t need diesel.”
That's where Dan, and millions of other Americans are wrong, argues JP.
"Diesel fuel is America’s blood," he says. "Unleaded (and by extension ethanol) is a bit like beer (pardon the pun) – life is more fun with it – but if it goes we’ll adjust. Try living without blood."
JP offers the following reality check - what he calls "a few fun facts if diesel were gone:"
1) No unleaded – you need diesel to get it to the pump?
2) No ambulances.
3) No electricity.
4) No back up power.
5) No distribution.
6) No trains.
7) No trucks.
8) No food.
9) No clothes.
10) No planes.
11) No medicine.
12) No military.
JP may be a bit radical in some of these "fun facts," but there's no denying he has a strong point.
He also raises some other concerns about the introduction of low-sulphur diesel. "The EPA (Environmental Protection Agency) has created near impossible standards for diesel passenger cars. He wonders if America has "sold her soul to the Middle East and poor planning?"
He points out that in just the last decade 40% of passenger cars in the EU have changed to diesel. Germany alone manufactured 313 million gallons of biodiesel in 2004. The U.S. will make 75 million in 2005. The whole E.U. in 2005 looks like 2 billion gallons.
"In summary," he says, "until the American perception of diesel and its capabilities is turned and our legislators wake up, we will fall further behind everyone else. And as the demand for diesel fuel rises outside our borders the effect will be severe."

Please let us know your opinion on the future of diesel. Is JP overly concerned, or too wedded to diesel?
