An Innovation A Day Keeps the Emissions Away

800px-New_Teslas_at_the_factoryJust about every day, I'm hearing about new innovation in electric vehicle (EV) technology on the market or in the works.

Sustainia, an annual guide to innovative sustainable solutions worldwide, just announced its 100 top picks. Among the companies were at least five in the EV space. One is Proterra, the electric bus company about which we've blogged before, for its EcoRide Fast Charging Electric Buses. Proterra says these buses get the equivalent (in terms of efficiency and emissions) of 20.8 mpg as compared to 5.25 mpg for hybrid, 3.86 mpg for diesel, and 3.27 mpg for CNG. These e-buses are seriously cleaner!

Honeywell & Safran made the Sustainia 100 list for its new electric taxiing system for airplanes, which is expected to equip A320 aircrafts with autonomous taxiing technology from gate to runway to save the CO2 equivalent per plane of planting 835 trees or eliminating 717 automobiles.

ChargePoint was on Sustainia 100 for the company's technology at 17,000+ EV charging stations nationwide. ChargePoint is clearly charging ahead -- with millions more in venture capital support recently secured and a new partnership with French electrical systems giant Schneider Electric.

Finally, there were two battery technology companies on the Sustainia list; Aquion Energy and Ambri are both making strides in renewable energy battery storage. My Sierra Club colleague Reed McManus wrote for the current edition of Sierra Magazine about research underway for EV batteries that will allow electric cars to charge faster and go further.

So is it competition or collaboration that is enabling these kind of advances? Tesla recently surprised many by announcing that it would open up its 172 current patents to any company that works "in good faith" to advance the EV market. When we read that "Nissan wants a three-way with Tesla and BMW" (not my words!) for supercharger technology, we know this kind of collaboration could mean that EV drivers are soon enjoying big benefits from this kind of corporate love-in.
