Plug-in hybrid technology being tested

Valence Technology has partnered with EnergyCS to produce a plug-in Prius hybrid for the city of Sacramento to test for fleet viability. Likewise, Canada's Manitoba Hydro is also testing plug-in hybrid vehicles and their impact on the electric grid.

While it is great these developments are occurring, it seems plug-in hybrid technology is still a couple of years away from reality, and I hope that fact doesn't stymie hybrid investment.

The technology powering plug-ins, particularly lithium-ion batteries, will rapidly evolve in the next decade. A fleet of plug-in hybrids might not be cost-effective for cities such as Sacramento in the short term. Nonetheless, current hybrid vehicles certainly are cost effective today for Sacramento, and their purchase helps invest in the future of plug-in hybrids, which will definitely be cost effective in the future.
