Is Natural Gas Fuel Dead Before it Gets Off the Ground?

The natural gas fuel revolution should have been in full swing by now, but Clean Energy Fuels and Westport Innovations are struggling to grow or make a profit. Is the revolution already over?

Apr 8, 2014 at 1:00PM

Just a few years ago, natural gas fuel seemed to be the answer for all of the United States' energy problems. It's in abundant supply domestically, prices are low, and the changeover from using gasoline to natural gas won't require a wholesale shift in the way consumers buy and consume energy.

But the natural gas fuel revolution seems to have lost momentum, and leaders Clean Energy Fuels (NASDAQ:CLNE) and Westport Innovations (NASDAQ:WPRT)have been market laggards in a year when companies with growth potential have been hot. What has happened? Is the natural gas fuel revolution dead or has the market just missed its growth story?

There's no single answer, but investors may be reconsidering the size of the market for natural gas fuels. Natural gas is developing into a great alternative for a niche in the market, not an alternative for you and I in our daily commute, as some had hoped.

Natural gas's momentum is gone
The appeal of natural gas fuel is easy enough to understand. According to Clean Energy Fuels, it can cost $1.50 per gallon less than diesel and results in 23% fewer emissions in the medium and heavy-duty markets they're targeting. Westport Innovations is making the transition easy, designing natural gas engines and equipment to convert consumer vehicles to natural gas. 

But natural gas's cost advantage can easily evaporate, mitigating the need to switch fuels at all. That's exactly what has happened over the past three years, killing some of the industry's momentum.

Rising natural gas prices aren't the end of the world for natural gas fuel, but they hurt. Between one-third and one-half of Clean Energy Fuels' fuel costs come from buying natural gas. As the price rises, it either squeezes margins for Clean Energy Fuels or makes the switch to natural gas less cost effective for customers, both bad trends for the industry.

If there was reason to think that the price of natural gas will fall to $2 per thousand cubic feet again soon I would say there's hope, but when prices were that low drilling for natural gas came to a halt. I don't see the price of natural gas falling much; there's also potential that oil will drop, hurting natural gas's cost advantage.

The U.S. is becoming energy independent
One of the great advantages natural gas once had is that it's abundant domestically relative to oil, which was imported from places like the Middle East. But U.S. shale drilling has changed that picture: net imports of oil have fallen from 60.3% of consumption in 2005 to just 28.5% last year. At the rate production is increasing, the U.S. could be energy independent by 2020.

That creates a tougher political environment for natural gas, which has been helped immensely by tax credits. In fact, last year $45.4 million of Clean Energy Fuels' revenue, or 12.8%, came from the volumetric excise tax credit.

If moving from oil use to natural gas doesn't cut energy imports and requires taxpayer subsidies to be successful, I don't see why a wholesale energy shift would happen. It would make more sense to put taxpayer money into truly clean energies that are already becoming competitive with oil.

Alternative energy competition is growing
Natural gas has a great sales pitch to the medium and heavy-duty trucking market, but shifting those markets isn't the ultimate goal of the natural gas industry. The aim was to capture significant share in the passenger market as well.

The problem today is that electric vehicles are becoming consumers' alternative fuel of choice, limiting the overall market. Tesla Motors (NASDAQ:TSLA) has proved that electric vehicles are desirable for consumers, and competitors are also stepping up their game in this space. It helps that there are now more than 20,000 public charging stations in the U.S., dwarfing the slightly more than 1,000 natural gas stations. 

To make matters worse, regional fleets operated by the likes of UPS and FedEx are testing using electric vehicles and fuel cells to power trucks. These regional fleets account for most natural gas fuel sold in the U.S. right now, and if an electric or hydrogen drivetrain can compete it would further hurt the natural gas story. 

The natural gas cost advantage also evaporates when compared to EVs for consumers, plus Tesla has proven that electric performance is far better than a natural gas vehicle. The expansion of natural gas simply took too long while electric vehicles solved many of the engineering challenges limiting their success. Today I see little upside in the consumer market for natural gas because alternative fuel vehicles will trend toward electric.

Infrastructure doesn't exist for a wholesale shift
The final challenge natural gas faces is infrastructure. It costs about $1 million to build a compressed natural gas fueling station; as of the last Energy Information Administration report there were only 447 public stations. That has expanded in the two years since the report, but CNG is in need of massive infrastructure.

Clean Energy Fuels and Westport Innovations have focused on the medium and heavy-duty markets, which is where America's natural gas highway has promise. But as I pointed out above, that emphasis limits the potential market for these companies and lowers return on investment in stations and engine technology.

Can natural gas fuel come back?
Natural gas could definitely be a big winner in the trucking market. Given the new products Westport Innovations is launching this year and the expansion of Clean Energy Fuels' network of stations, the alternative is very viable. Westport Innovations recently said natural gas had penetrated 1.7% of the 215,039 Class 8 trucks in the U.S. by the end of fourth-quarter 2013 and is rapidly increasing shipments. But this came during the same year the company reported a $185.4 million loss, showing that uptake isn't happening fast enough to make money.

The challenge for these companies is that the changeover to natural gas is expensive, while the fuel's cost advantages aren't necessarily long lasting. Trucking fleets may switch over gradually, but the market will be somewhat limited. Natural gas will also have trouble catching on in markets like consumer vehicles because alternatives provide better performance and more infrastructure.

Investors need to adjust their growth expectations lower and understand the headwinds these companies face. Natural gas is an interesting alternative fuel option but it isn't the no-brainer investment some thought a year or two ago. That makes these stocks high risk, particularly as alternatives improve.

1 Key Step to Get Rich

Our mission at The Motley Fool is to help the world invest better. Whether that’s helping people overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we can help.

Feb 1, 2016 at 4:54PM

To be perfectly clear, this is not a get-rich action that my Foolish colleagues and I came up with. But we wouldn't argue with the approach.

A 2015 Business Insider article titled, "11 websites to bookmark if you want to get rich" rated The Motley Fool as the #1 place online to get smarter about investing.

"The Motley Fool aims to build a strong investment community, which it does by providing a variety of resources: the website, books, a newspaper column, a radio [show], and [newsletters]," wrote (the clearly insightful and talented) money reporter Kathleen Elkins. "This site has something for every type of investor, from basic lessons for beginners to investing commentary on mutual funds, stock sectors, and value for the more advanced."

Our mission at The Motley Fool is to help the world invest better, so it's nice to receive that kind of recognition. It lets us know we're doing our job.

Whether that's helping the entirely uninitiated overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we want to provide our readers with a boost to the next step on their journey to financial independence.

Articles and beyond

As Business Insider wrote, there are a number of resources available from the Fool for investors of all levels and styles.

In addition to the dozens of free articles we publish every day on our website, I want to highlight two must-see spots in your tour of fool.com.

For the beginning investor

Investing can seem like a Big Deal to those who have yet to buy their first stock. Many investment professionals try to infuse the conversation with jargon in order to deter individual investors from tackling it on their own (and to justify their often sky-high fees).

But the individual investor can beat the market. The real secret to investing is that it doesn't take tons of money, endless hours, or super-secret formulas that only experts possess.

That's why we created a best-selling guide that walks investors-to-be through everything they need to know to get started. And because we're so dedicated to our mission, we've made that available for free.

If you're just starting out (or want to help out someone who is), go to www.fool.com/beginners, drop in your email address, and you'll be able to instantly access the quick-read guide ... for free.

For the listener

Whether it's on the stationary exercise bike or during my daily commute, I spend a lot of time going nowhere. But I've found a way to make that time benefit me.

The Motley Fool offers five podcasts that I refer to as "binge-worthy financial information."

Motley Fool Money features a team of our analysts discussing the week's top business and investing stories, interviews, and an inside look at the stocks on our radar. It's also featured on several dozen radio stations across the country.

The hosts of Motley Fool Answers challenge the conventional wisdom on life's biggest financial issues to reveal what you really need to know to make smart money moves.

David Gardner, co-founder of The Motley Fool, is among the most respected and trusted sources on investing. And he's the host of Rule Breaker Investing, in which he shares his insights into today's most innovative and disruptive companies ... and how to profit from them.

Market Foolery is our daily look at stocks in the news, as well as the top business and investing stories.

And Industry Focus offers a deeper dive into a specific industry and the stories making headlines. Healthcare, technology, energy, consumer goods, and other industries take turns in the spotlight.

They're all informative, entertaining, and eminently listenable ... and I don't say that simply because the hosts all sit within a Nerf-gun shot of my desk. Rule Breaker Investing and Answers contain timeless advice, so you might want to go back to the beginning with those. The other three take their cues from the market, so you'll want to listen to the most recent first. All are available at www.fool.com/podcasts.

But wait, there's more

The book and the podcasts – both free ... both awesome – also come with an ongoing benefit. If you download the book, or if you enter your email address in the magical box at the podcasts page, you'll get ongoing market coverage sent straight to your inbox.

Investor Insights is valuable and enjoyable coverage of everything from macroeconomic events to investing strategies to our analyst's travels around the world to find the next big thing. Also free.
