The Colorado Energy Office, along with the Regional Air Quality Council and the Colorado Department of Transportation, has selected four locations for compressed natural gas (CNG) fueling stations with funding from the ALT Fuels Colorado grant program.

The ALT Fuels Colorado program is designed to remove barriers to the adoption of alternative-fuel vehicles by addressing the current lack of fueling infrastructure, along with providing incentives to offset incremental vehicle costs. To date, the Colorado Energy Office has issued awards for 15 CNG stations, according a release from the office.

The winning developers and station locations of the third round of funding are Ward Alternative Energy in Henderson, Sparq Natural Gas in Rifle, VNG.CO in Denver, and Trillium CNG in Gunnison.

Additionally, awards were made for co-located electric vehicle charging and propane fueling stations at three previously awarded sites in Fort Collins, Loveland, and Greeley.

Through the Federal Highway Administration’s Congestion Mitigation and Air Quality Improvement (CMAQ) program and the Colorado Department of Transportation, ALT Fuels Colorado will provide $30 million over a four-year period from 2014 to 2017 to accelerate Colorado’s adoption of alternative-fuel vehicles.

Under the Colorado Energy Office's stewardship, $15 million of the CMAQ funds will be used to develop alternative fueling stations along major statewide transportation corridors, while the remaining $15 million will be awarded to successful applicants for the purchase of natural gas, electric, and propane-powered fleet vehicles within the state’s air quality non-attainment and maintenance areas, according to the release.
