Natural Gas Engines

Natural gas vehicles are predominantly in the public sector, 20% of the 80,000 municipality buses use them[1]. In the trucking industry, less than 1% of the 200,000 trucks have natural gas engines. They have also have found niche applications in refuse trucks (2,500), shuttle buses and delivery trucks (10-20,000), school buses (3,000) and light vehicle fleets (20,000)[2].

Natural gas engines are expected to gain wider acceptance towards 2010 when their fuel efficiency is expected to be 95% of diesel engines[3]. The newer engines increase the combustion efficiency by a richer mix of oxygen and fuel and by compressing the mixture before it is burnt. More air in the mix also reduces the NOx emitted after the gas is burnt. Diesel engines will emit 6 times more NOx than natural engines.

Emission Standards and Cost of Engines

By 2010, the emission standards for heavy and medium-duty diesel engines are slated to be far more stringent. Fleets are switching to natural gas engines to avoid the higher costs of environmental compliance required of diesel engines. According to Dee Kapur, the President of the International Truck and Engine, the cost of a medium-duty truck will rise by $5,000 to $6,000 to meet the 2007 emission standards and as yet an undetermined figure to comply with the 2010 standards. The cost of heavy-duty trucks will rise by $10,000[4]. The ultra low-sulfur that would have to be used is reported to cost an additional 14-16 cents for every gallon.

Supply of Natural Gas

In the USA, the supply of domestically extracted natural gas is increasing and will encourage its use in transportation. According to a recent study of Navigant Consulting, supply of natural gas is increasing as unconventional sources of natural gas, shale gas, coal bed methane and tight gas, rise. Navigant’s estimates show that unconventional natural gas supply increased by 65% to 8.9 Tcf per year in 2007 from 5.4 Tcf per year in 1998 while its share increased from 28% of total supply to 46% in 2007[5].

More recently, production has surged especially in Texas and Wyoming[6]. The production increase is likely to be sustained because it is propelled by successful implementation of new technologies, i.e., horizontal drilling[7] which is able to draw on natural gas deposits in shale. These technologies can tap into the large reserves[8] of natural gas available in Barnett Shale deposits which were previously inaccessible[9].

In addition, supplies of liquefied natural gas are increasing dramatically[10]. The USA is expected to increase its imports from 2.1 Bcf / day in 2007 to 12.8 Bcf / day in 2016[11]. While in the past natural gas as a by-product of oil extraction was burnt, it is now stored as liquefied natural gas and increased transported and traded across the world.

Westport Innovations

At a time stock markets in the USA are expected to move sideways throughout 2010, the companies that have invested in their future and are poised to reap the benefits in the near term are most likely to see their stocks gain. Westport Innovations, a Vancouver based manufacturer of natural gas engines, fits the profile. It has gained market share in the market for natural gas engines in the size range of 5.9 and 8.9 liter. Over the last three years, it reinvested its profits to develop a market for heavy duty natural gas engines. Profits could rise sharply as expenses on market development decline and revenues from heavy duty vehicles increase.

The surpluses from CWI helped to fund the expenses for the development of heavy duty vehicles. In fiscal 2007 (ending March 31st), the operating margin was $8.7 million (after deducting $ 8 million in R&D which were expensed to comply with US Accounting rules) on sales of $58 million or 29% on sales (excluding the R&D expenses). The margin at $21 million (after excluding R&D expenses) dropped to 19% in 2009 with sales of $110 million. The company began offering a LNG solution for 15 liter engines in early 2007 through Westport Power Inc. The expenses incurred for development of the market for heavy-duty trucks led to an increase in losses from $10.3 million or $0.41 per share in 2008 to $24.4 million or $0.81 per share in 2009, expenses for heavy duty trucks increased by $12.6 million.

Overall, the market for heavy duty trucks plummeted from a peak of 284,000 units in North America in 2006 to 145,000 units in 2008. Westport’s own sales of heavy duty vehicles dropped from 69 in fiscal Q2 2009 to 14 in 2010 and the YTD from 70 to 28. Due to a weak economic recovery, overall heavy duty truck sales are unlikely to recover significantly. Westport, however, will benefit from the purchase by the Long Beach and Los Angeles ports, a market it has been able to enter, of 8000 natural gas trucks that will be purchased over the next five years. The DOE has also allocated funds for the purchase of 2800 vehicles for the Clean City program. The cost differential between diesel and natural gas engines will be narrowed as owners of diesel engine trucks comply with more stringent emission regulations in 2010 and the Natural Gas Act, currently under consideration in the Senate, doubles the tax credit to $64,000. Surging supply of natural gas within the USA and imported LNG has increased the relative cost of diesel which now sells in the range of $5 a gallon in Southern California compared to $3.20 for natural gas.
