As the demand for cleaner energy rises, port authorities are tasked with finding eco-friendly solutions that maintain productivity without straining budgets. Propane has long served as a reliable energy source at ports, powering various equipment while significantly reducing emissions. Now, renewable propane emerges as an ultra-low-carbon alternative, offering similar benefits but with even lower emissions compared to conventional propane and diesel.
Renewable propane is derived from feedstocks like used cooking oil and animal fats, resulting in a carbon intensity that is up to four times lower than conventional propane. Studies show that propane-powered port tractors emit 99% fewer nitrogen oxides and nearly eliminate particulate matter compared to diesel. This positions both renewable and conventional propane as effective options for enhancing sustainability in port operations.
Transitioning to renewable propane is seamless for ports already using conventional propane, as it can be utilized in existing engines and infrastructure without costly overhauls or extensive retraining. This ensures that ports can maintain high operational uptime while adopting cleaner energy solutions.
The production of renewable propane is rapidly increasing, with U.S. output expected to grow from 4.5 million gallons annually to 100 million gallons in the coming years. As technology advances and new feedstocks are explored, renewable propane presents a viable path for ports aiming to reduce emissions and support global trade.
