The conversation around clean energy for student transportation has never been as loud as it has since the EPA announced the Clean School Bus funds. As that conversation has grown, it’s becoming more apparent than ever that it will take a diverse energy mix to quickly enact real emissions reductions in student transportation. With that in mind, more school transportation directors are implementing multiple alternative energy sources into their fleet, like propane autogas and electric, to provide a safe, clean, and healthy ride for students.

This trend has caused a demand for new technology and innovations that make operating a clean multi-fuel fleet as simple as operating one with conventional fuels. That means for a solution to be viable, it needs to be reliable, efficient, and affordable in addition to being clean.

One of the industry’s latest innovations combines each of those qualities by building off the decades of benefits propane autogas has been able to offer school districts. Thanks to microgrid technology, propane is now reducing emissions along the path to zero even further as a power generation solution for electric bus recharging infrastructure.

An example of this new technology is the portable dual-purpose standalone fueling system from Propane Fueling Solutions that can refuel propane autogas vehicles and recharge electric school buses utilizing a microgrid powered by renewable energy sources like wind, solar, and a propane-powered generator. School districts that operate both propane autogas and electric buses can realize reliable and affordable benefits from the infrastructure. Best of all, school districts can use EPA funding to apply for the infrastructure at a fraction of the cost compared to traditional charging infrastructure.

Reliability When It Matters

School districts have always been confident their propane autogas fleets will remain running even during times when the electric grid fails. While other energy sources may be out of commission, propane autogas is a portable energy source that can still be delivered when the electric grid is down, providing districts with an added layer of resiliency from interruptions. Not to mention, propane autogas school buses have a range of up to 400 miles on a single refuel, ensuring districts can run routes without worry of running out of fuel.

Similarly, because the dual-purpose standalone fueling infrastructure is self-contained and disconnected from the electric grid, transportation directors can have peace of mind that their electric buses will not be grounded. With solar and wind power alongside the propane-powered generator, electric buses can recharge regardless of the weather. The system is also portable and can be moved and installed in as little as 24 hours in areas where it’s needed most.

Cost-Effective Solutions

More than almost any other fleet type out there, it’s critically important for school districts to find a balance between being financially sustainable and environmentally sustainable. It’s one of the main reasons the EPA made billions in federal funding available to implement clean energy solutions.

While it may seem like a dual-fuel infrastructure solution would be more costly because it offers two energy solutions, that’s not the case. Compared to traditional electric bus charging infrastructure, the dual-fuel equipment is significantly less expensive because it doesn’t require the same site prep or other costly charges that are incurred with connecting with grid infrastructure. In fact, it cuts costs by as much as 75% or more. That affordable price allows districts to stretch their Clean School Bus funds further.

As more transportation directors turn to a variety of alternative energy sources to meet the needs of their buses, solutions like the dual-fuel infrastructure will make operating a 100% clean fleet possible. It’s through innovative solutions like this that school transportation will continue to move further down the path to zero emissions.
