Natural Gas Vehicle Buyers’ Guide, these manufacturers
collectively represent 182 light-duty, 76 medium-duty
and 64 heavy-duty vehicle engine choices. And those
numbers are growing—partly because in March 2011,
EPA adopted a new approach that streamlines certi-;cation. In addition to attracting more conversion
companies with the simpli;ed process, EPA expects
the new approach also will result in cost savings. And
that will spur even more competition and systems.
CNG FUELING INFRASTRUCTURE
In 1996, the Gas Research Institute (now Gas
Technology Institute), American Gas Association and
the Natural Gas Vehicle Coalition (now NGVAmerica)
released a groundbreaking “National NGV Industry
Strategy” (the “Strategy”) after lengthy research, analysis
and economic modeling by three separate consulting
;rms (including NGVi).
To spur NGV adoption and overcome the enormous
cost of building the fueling infrastructure, the Strategy
intentionally focused its attention on high-fuel-use ;eets,
such as transit agencies, refuse trucks and delivery ;eets.
So, the growth in ;eet adoption in recent years has been
by design, not by accident.
