Clean Energy Fuels Zero Now Program

Run a next-generation natgas fleet.

Pay a last-generation diesel price.

You can now lease or purchase a new natural gas fleet for the price of a diesel fleet with Clean Energy's Zero Now Program. Not only will you be running the cleanest rides on the road at no additional cost, we'll even guarantee a fuel price significantly lower than diesel through the term of the lease or purchase.


Zero Now Program

Zero emissions. Zero added cost.


With Clean Energy's Zero Now Program the lease or purchase of a natural gas fleet is now on par with a diesel fleet. You can choose from a variety of manufacturers, as long as the trucks are equipped with the new Cummins Westport ISX12N engine.



Clean Energy will also guarantee a fuel price for the new trucks that is significantly discounted to diesel for the term of the lease or purchase.


Clean Energy will also work with customers to obtain any available grant funding that could make the switch to natural gas even more affordable.


Clean Energy operates over 110 natural gas fueling stations which can accommodate Class 8 trucks and are placed strategically around the United States and Canada, with plans to open additional locations in the future.



You have the option of choosing either CNG or LNG vehicles, and Clean Energy will also make its Redeem™ renewable natural gas available for CNG or LNG trucks wherever possible.

Zero Emissions NOW

The New Standard

After several studies linking poor air quality and health problems to diesel emissions, many large cities around the world have set dates to restrict or entirely ban the use of diesel to meet obligations under the Paris climate agreement.

Cities in the United States are now taking similar action, especially in densely populated areas, busy ports and trucking corridors, which suffer the nation's worst air quality.

Responsible fleet owners and shippers now have an easy alternative to also meet the optional Low NOx Standards of 0.02g NOx set by the California Air Resources Board (ARB), which are 90% lower than current Environmental Protection Agency (EPA) emission standard.

Redeem Renewable Natural Gas

The ZERO NOW solution is fueled by Redeem by Clean Energy. The first renewable natural gas made entirely from organic waste for commercial vehicle fuel.

To make Redeem, Clean Energy captures and extracts biomethane gas that is released into the atmosphere as organic waste decomposes. Major sources of naturally-occurring methane gas are landfills and farms with animal waste. Next, the gas is processed and purified. Then it is made available exclusively to Clean Energy customers at fueling stations nationwide.

Redeem fuels hundreds of vehicle fleets across the nation every day. Any natural gas vehicle from a taxi to an 18-wheeler can use Redeem in either CNG or LNG form. Redeem can meet 100% of the fueling requirements of any natural gas vehicle.

Redeem Dollar Deal

It's ultra-clean. It's renewable. It's American-made.

And for the next 12 months it's $1 a gallon.

Heavy-duty truck fleets are under increasing pressure to meet strict emissions standards, which is why Clean Energy is introducing our Redeem Dollar Deal program to help customers switch to a zero emissions solution. The first 250 qualifying trucks will be able to lock in a $1 per gallon rate on Redeem renewable natural gas for one year, available at all Clean Energy stations throughout California.

Renewable Natural Gas Roadmap

Renewable Natural Gas Roadmap

Compare With Electric

As municipalities worldwide are banning diesel and switching to clean alternatives, many people outside the transportation industry think electric will be the zero emissions solution, even for heavy-duty applications.

But the first electric heavy-duty trucks aren't in mass production yet and there are many concerns about electric's ability to meet current operational and economic requirements.

Electric vehicles will be costly to buy and to maintain and will raise operational costs for shippers and carriers via increased vehicle weight, decreased driving ranges, and lack of charging infrastructure.

Zero Now First Electric Heavy-Duty Trucks

Electric vehicles are not zero impact

Heavy-duty trucks will require a considerable amount of energy to recharge. A significant increase in demand for electricity may be met through an increase in coal production.

Exponential demand for rare metals, cobalt and lithium, used in battery cells has created a human rights and environmental crisis in unregulated and developing countries.
