NISKAYUNA, N.Y. -- December 13, 2012

Researchers at GE Global Research, the General Electric Company’s (NYSE: GE)
technology development arm,  have  achieved a first step in reducing the cost
of clean fuel, zero emission buses, with a vehicle powered by GE’s new
Durathon™ battery in tandem with a lithium battery and a hydrogen fuel cell.
This promising development of a new energy management system could help
accelerate both fuel cell acceptance and electrification of bus fleets,
delivery trucks and other larger, heavy-duty vehicle fleets enabling clean
vehicle technologies. To see a video demonstration of the bus – click here –.

In 2010, the GE team first successfully demonstrated a dual battery system on
a zero tailpipe emissions hybrid transit bus by pairing a high-energy density
sodium battery with a high-power lithium battery. Now, two years later,
further testing using GE’s new Durathon™ battery has produced even better
results. GE researchers believe that the kind of energy management
architecture they’re building will allow for a bus to operate at full
performance with a significantly smaller fuel cell than previously possible.
The fuel cell power plant represents a significant cost and GE’s energy
management system has the potential to bring down those costs by up to 50%.

“For years fuel cells have been talked about as a clean transportation
alternative but cost has always been a roadblock to widespread adoption,” said
Tim Richter, Systems Engineer in the Electric Propulsion Systems Lab at GE
Global Research. “With GE’s battery technology and dynamic dual battery
management system, we’re starting to push that roadblock aside.”

Richter added, “What we want to deliver is a cost-effective bus that emits no
harmful pollutants.”

The research is being done as part of a $13 million research project GE is
engaged in with the Federal Transit Administration (FTA) and Northeast
Advanced Vehicle Consortium, funded under the National Fuel Cell Bus Program.

“GE’s Multi-Energy High Voltage Energy Management Technology releases vehicle
designers from the traditional constraints of single battery configurations,”
Richter continued. “GE’s Energy Management Technology combined with two or
more batteries or energy devices allows GE to enable various power-to-energy
configurations that match the vehicle needs. By leveraging the right battery
to do the right job, overall system cost and efficiency can be improved.”

Most types of batteries today come with a trade-off between power and energy
storage. For example, lithium batteries, provide a lot of power for
acceleration, but are not optimized to store energy for driving range. Sodium
batteries, like GE’s Durathon™, are on the opposite side of the spectrum. They
store large amounts of energy, but are less optimized for power. GE’s dual
battery combines the best attributes of both chemistries into a single system.
In the hybrid transit bus demonstration, the lithium battery focused on the
high power acceleration and braking, while the Durathon™ battery provided an
even electric power flow to extend the bus range.

Many of the 846,000 buses registered in the U.S. (including most of the 63,000
transit buses and 480,000 school buses) travel less than 100 miles per day.
Enabling more of these buses to transition to a fuel cell-battery, zero
emissions platform would dramatically reduce CO[2] emissions and petroleum
fuel consumption.

GE’s Durathon™ batteries are produced at the company’s start-up Energy Storage
business in Schenectady, N.Y. which opened in July 2012. Starting next year,
thousands of Durathon™ batteries will be shipped to the telecommunication
market, enabling fuel efficiency improvements and emission reduction at diesel
generator powered cell sites across Africa, the Middle East, and South East
Asia, and providing reliable back-up power at cell sites which cope with
intermittent supply of electricity from the grid. Another key market is the
energy space, where this battery technology enables renewable power producers
to meet stringent grid interconnection requirements, helps grid operators
stabilize their grid and electricity users reduce their utilities bill by
avoiding demand surcharges, and enables arbitrage. Future applications of the
battery extend well beyond telecommunications and the grid to energy-efficient
buses, locomotives and mining vehicles. Over the next few years, GE expects
the Energy Storage business will produce $1 billion in annual revenues as
orders for the new battery increase.
