Proterra Releases Patents For Fast-Charging Technology

Proterra Releases Patents For Fast-Charging Technology

Since it was founded in 2004, Proterra has become one of the biggest names in zero-emission bus design in the world.  Last year, Fortune Magazine went so far as to call the company the Tesla of electric buses. According to Bloomberg BNA, the company currently controls about 80 percent of the U.S. market for electric buses. You can find Proterra’s electric buses in cities all over the country – from Seattle to Reno to Nashville.

What distinguishes Proterra from its competitors isn’t just its commitment to electric vehicles; it’s the company’s proprietary rapid-charging technology that allows their buses to be recharged in as little as 10 minutes. This technology has alleviated one of the chief concerns many transit authorities have had about electric buses in the past – namely, the equipment downtime necessitated by long charging times. With Proterra’s overhead charging system, its buses can recharge quickly at stops and operate all day long. Now, in an effort to encourage other industries to adopt electric vehicles, Proterra has announced that it will make three of the patents on its fast-charging system open to the public.

“We really want to stay focused on perfecting electric vehicles for the transit bus industry,” said Proterra CEO Ryan Popple in an interview with Fortune. “One of the ways we can help other entities not have to reinvent the wheel or reinvent the charger, is to open this up, provide information, and supplier access and let other companies go after applications that really aren’t core to us or our customers.”

This isn’t the first time companies in the alternative fuel market have made their technologies open source. In the past, both Toyota and Tesla have released electric vehicle patents to the public. In doing so, they hope to foster further competition and innovation in the electric vehicle market, and ease concerns about electric vehicles that have been perpetuated by gas companies. Releasing proprietary technology to competitors might seem counterintuitive from a business standpoint, but in fact it could be good for all of these companies in the long run.

Orange County, California Unveils Hydrogen Fuel Cell Bus

Orange County, California Unveils Hydrogen Fuel Cell Bus

The Orange County Transportation Authority (OCTA) is committed to making their fleet of buses as energy efficient and environmentally friendly as possible. Currently, 97 percent of the fleet runs on clean-burning natural gas. By the end of 2016 they expect the entire fleet to be powered by natural gas, with one notable exception.

On May 23, the OCTA hosted an event to unveil its first zero-emission hydrogen fuel cell bus. Wrapped in a graphic decal of California poppies, the bus will roam the streets of Orange County in a two-year demonstration of hydrogen fuel cell technology. The $2.6 million dollar project is being funded by the Federal Transit Administration’s National Fuel Cell Bus Program.

The bus, which operates by converting chemical energy in hydrogen fuel into electricity, emits only water as exhaust and is completely silent. Likewise, it provides a much smoother and more comfortable ride for passengers than older buses powered by large diesel engines. It can run on a single charge for more than 200 miles, and can be refueled in a matter of minutes. Electric battery-powered buses, on the other hand, can take several hours to charge.

The OCTA has applied for additional funding from the California Air Resources Board in hopes of adding 10 more of the buses to its fleet in the future. They are now the fourth transportation agency in California to operate a hydrogen fuel cell bus.

It’s remarkable how far hydrogen fuel cell technology has come in just a few years. As the cost of the technology continues to fall, we may see more of these vehicles on the road sooner than you might think.
