Energy tax provisions slated for the massive economic stimulus bill include expanded incentives for plug-in electric vehicles.
Now that’s some seriously good news even though gas prices are the lowest they have been in a long time.
The Senate unveiled yesterday that they would mark up the $272 billion tax measure as they are a promising way to help curb reliance on oil imports by effectively allowing electric power to substitute for oil-based transportation fuels. The energy provisions total more than [...]

Whatever you do, don’t call it a battery.
A research group at the University of Texas at Austin has taken a carbon-based nanomaterial called graphene, and developed it into a device that has the potential to vastly improve upon the energy storage capacity of batteries. Reportedly, graphene could also double the current maximum storage capacity of the group of battery alternatives known as ultracapacitors.
If the research group’s findings bear out when applied to reality, it could mean a complete phase change in the way we approach energizing not only our transportation sector, but our entire energy infrastructure.

Enova Systems and IC Corporation have delivered a plug-in hybrid diesel electric bus to Denali National Park for use in carting visitors around the pristine wilderness.
The bus (similar to the one pictured above) has a GVWR of 27,500 pounds, carries up to 38 passengers and uses up to 70% less fuel than a similarly equipped conventional bus — so if the bus got 10 mpg with a conventional engine, it could get 30 mpg using Enova’s hybrid system.

In a slew of announcements this week, a picture of what the future of plug-in vehicle charging might look like is starting to emerge.
The Problem:
There are 54 million garages for the 247 million registered cars in the US, meaning that the majority of cars are parked overnight in parking structures, parking lots or curbside.
As a result, most potential plug-in vehicle consumers do not have an adequate place to charge their vehicles. This problem is even more pronounced in urban areas like San Francisco, where only about 16% of cars are parked in garages overnight and the rest end up curbside or in parking lots.
Also, although the US power grid probably has enough overall capacity to supply energy to a nation of plug-in vehicles, it may not have the ability to charge them when they all plug-in and demand energy at the same time — say 6 pm every weekday.

Editor’s note: This post is a lead-in story to the Gas 2.0 interview with Mil Ovan, Senior Vice President and Co-founder of Firefly Energy.
Last week John McCain, the presumptive presidential nominee for the 2008 Republican ticket, suggested that a $300 million government-sponsored competition would be a good way to spur development of next generation battery technologies.
His comments generated debate in the blogosphere and around the United States. Meanwhile, Barack Obama, the presumptive presidential nominee for the Democratic ticket, called McCain’s proposal a gimmick suggesting that $300 million was not enough.
Regardless of my feelings about the proposed competition or the candidates themselves, it got me thinking about just who might win it if it were to become a reality. All that thinking led to this post, and, hopefully, to several others that will look at the most promising next generation battery technologies on the horizon.
This week I’ll start with Firefly Energy.

Editor’s note: This interview is a companion piece to Part I of the Gas 2.0 series about who might win John McCain’s proposed $300 million dollar battery competition if it were to become reality.

Firefly Energy is one of the companies that made it to my short list. Founded in 2003, they have been working on reinvigorating old-hat lead-acid battery technology in such a way that it would become brand new and cutting edge once again.
Firefly’s innovation is that they’ve taken the heavy lead plates you’d find in a classic lead-acid battery and replaced them with a light carbon-graphite microcell foam that’s been impregnated with lead.
I recently had a chance chat with Mil Ovan, Senior Vice President and Co-founder of Firefly, about the company, their take on McCain’s competition, Firefly’s battery technology, environmental worries about lead, the Oasis battery, electric vehicles and the company’s plans for the future.

Hot on the heels of the announcement that Mercedes will produce electric cars, comes the news that fellow German manufacturer Volkswagen plans to produce a test fleet of plug-in hybrid electric cars by 2010.
A few months ago, to much excitement from the automotive press, the company unveiled a diesel-electric Golf but, according to VW chief Martin Winterkorn, “the future belongs to electric cars.” To help in mapping out the road to this electric future, the company have unveiled a plug-in hybrid powertrain, called the Twin-Drive, which will make its first appearance in a Golf kitted out with a 122-horsepower diesel engine, twinned with an 82-horsepower electric motor.

Plug-in hybrid, all-electric or fuel cell? Car-makers are hedging their bets on what will emerge as the next generation engine technology of choice – now it seems another alternative approach could well be set to enter the mix. Scottish engineering firm Artemis Intelligent Power has tested a hybrid system that it claims can cut carbon emissions by 30%, with the added advantage that it is better suited to inter-urban journeys than conventional hybrids like the Toyota Prius.
In common with other hybrids, the system employs a regenerative braking system that stores energy as the vehicle slows down, and feeds it back into the engine as it accelerates. The key innovation is that instead of storing the energy in a battery, the new system stores it in a hydraulic accumulator.

First Flex-Fuel Plug-in Hybrid Electric Vehicle
As part of a push by the US Department of Energy (DOE) to make plug-in hybrid electric vehicles (PHEVs) cost competitive with other cars by 2014, Ford has delivered a plug-in hybrid electric flex-fuel Escape to the DOE to join its test fleet of other PHEVs currently undergoing research and testing.
The vehicle is equipped with a 10 kilowatt lithium ion battery that can take it up to 30 miles at speeds under 40 mph before needing to fire up its fuel-fed hybrid-electric engine. After that, the hybrid-electric engine kicks in and can deliver a fuel economy of 88 mpg in the city and 50 mpg on the highway when using E85 (85% ethanol/15% gasoline blend).

UC Davis’s Institute of Transportation Studies has prepared a sort of primer for “non-battery experts” on the pros and cons of different battery technology for use in plug-in hybrid electric cars (PHEVs). The report, called Batteries for Plug-in Hybrid Electric Vehicles (PHEVs): Goals and the State of Technology circa 2008, discusses:
- the basic design concept of PHEVs and inherent trade-offs in different battery technology.
- the current state of the most common battery chemistries, including nickel-metal hydride (NiMH) and lithium-ion (Li-Ion), and their abilities to meet the needs of PHEVs
- potential trajectories for further improvement in battery technology
