Sustainable fleets report: Propane posts lowest fuel cost

Here are some of the findings from the fourth annual State of Sustainable Fleets Market Brief, authored by clean technology consulting firm Gladstein, Neandross & Associates.

• The federal government and California have adopted rules requiring an 80 percent reduction in nitrogen oxide emissions from diesel engines.
• More than $32 billion per year, on average, in public incentive funding for clean vehicles and infrastructure will be available for the next four to five years.
• A total of 13 states and the District of Columbia have passed or are considering some form of California’s zero-emission vehicles (ZEV) sales mandate on manufacturers, and these same states are expected to consider California’s ZEV purchase mandate on fleets.
• U.S. renewable diesel production doubled from 2021-22 to 800 million gallons, and renewable natural gas replaced nearly all fossil natural gas in California transportation for the second year in a row.
• In 2022, compressed natural gas averaged $2.73 per diesel-gallon-equivalent, and propane averaged $2.10 per-gasoline-gallon equivalent compared to an average of $5.78 per gallon and $4.79 per gallon for diesel and gasoline, respectively.
• Orders for medium- and heavy-duty battery-electric vehicles surged 640 percent, with nearly 30,000 medium-duty orders and 2,400 heavy-duty battery-electric school bus orders in 2022.
• At least half of fleets across 11 different fleet types, including logistics, transit, school, cargo and delivery fleets, have operated a medium- or heavy-duty battery-electric vehicle in the annual survey, and 92 percent of those fleets plan to grow their use.
• Supply chain disruptions have raised the price of medium- and heavy-duty battery-electric vehicles, and delays for electrical service have caused multi-year delays for some deployments.
• The public hydrogen station network grew 12 percent, and the first plans to build station networks outside California were announced for the central, mid-Atlantic and southwestern U.S.
