Corvus Energy ITS 2010 White Paper: May 19, 2010

Lithium Power – Energy Systems for the Next Generation of Vessels. Power for a Green Future

Brent Perry (speaker/co-author), George Roddan (co-author), Neil Simmonds (co-author), Corvus Energy Limited, Canada

SYNOPSIS
A brief description of the benefits of lithium energy battery technology, will be followed by a brief history of its growth, and a comparison of modern battery systems.

There will then be brief descriptions of working scenarios and the benefits of hybrid and electric applications, including an outline of how to mitigate costs, improve ROI, and develop an understanding of the impact on the environment.

The paper will touch on all aspects of the benefits of using lithium technology today, and how it will be impacting the future of vessel design, construction and use in today's vessels. It will demonstrate the financial and environmental gains that are possible today.

Corvus Energy Debuts Breakthrough Lithium-Ion Battery for Marine Propulsion Systems at International Tug & Salvage (ITS 2010) Conference, May 17-21

New “ BRAtt class” training tugs to feature Corvus Energy’s proprietary technologies

VANCOUVER, B.C.—Corvus Energy (www.corvus-energy.com), harnessing the power of large format lithium-ion battery systems for marine propulsion, will spotlight its proprietary technology at the International Tug & Salvage (ITS 2010) Conference May 17-21 at the Westin Bayshore Hotel in Vancouver, B.C. Corvus Energy executives will be on hand throughout the event at booth #121.

The conference marks the world debut of “ BRAtt class” training tugs, the first of which will feature Corvus Energy’s battery and management system utilized as the house power bank.The first BRAtt , a direct diesel-powered version, will be available for demonstration to ITS registrants. This tug will be followed up by delivery of an all-electric BRAtt and a hybrid diesel-electric BRAtt to the Western Maritime Institute in 2011.

“The BRAtt tugs will provide an important platform to introduce our powerful, maintenance-free lithium-ion battery technology as a viable alternative to conventional propulsion systems,” said Corvus Energy CEO Brent Perry. “Fuel savings and decreased maintenance in a hybrid can provide ROI in only a few years, with a huge benefit to the environment in the form of decreased emissions.”

The BRAtt training tugs are the joint brainchild of Ron Burchett and Vancouver-based Naval Architects Robert Allan Ltd. (www.ral.ca)--a collaboration that recognized the global need for cost-effective Z-drive training vessels. The 7.8 metre long, 450 horsepower BRAtt features most of the same technology and operating systems as found in full-size Z-drive tugs. It is also designed to be an affordable alternative to full-sized tugs for harbour duties, including boom deployment, yarding and line-handling.

To date, the marine industry has been unable to take full advantage of hybrid or full electric propulsion technology due to the large size and weight of traditional lead-acid batteries. Corvus Energy’s lithium-ion batteries are smaller, lighter and more powerful—and the battery chemistry and proprietary battery management system allows these batteries to last up to 10 times longer than lead-acid batteries.

Corvus Energy’s combined battery technologies provide superior power in a standard Group 8D format. The battery module can be integrated into existing applications or can be configured to meet storage requirements from 6.2kWh into the tens of thousands of kWh.

Corvus Energy and Dow Kokam Sign Exclusive Contract for Sales of Lithium Polymer Cells to In Select Marine Markets

Battery technologies provide hybrid and full electric propulsion alternatives

RICHMOND, B.C.— Corvus Energy (www.corvus-energy.com), providing first lithium-ion battery developed specifically for the marine propulsion market, has entered into an exclusive distributor contract with Dow Kokam (www.dowkokam.com) for sales of its advanced lithium polymer cells to the marine industry in select marine markets .

Providing marine hybrid and full electric propulsion by harnessing large format lithium-ion battery systems, Corvus Energy’s proprietary battery management system, combined with Dow Kokam cells, provide a powerful and maintenance-free alternative to traditional lead-acid battery technology.

“Dow Kokam provides the world’s most technologically advanced lithium polymer cells, providing a key component in our battery technology for marine applications,” said Corvus Energy CEO Brent Perry. “Dow Kokam’s patented lithium polymer Z fold cell structure technology allows higher energy density, higher discharge rates and a longer cycle life than any other cell manufacturer.”

Brent Perry said Corvus Energy's combined technologies provide a viable compliment or alternative to conventional propulsion systems in tugs and other working vessels. He noted that fuel savings and decreased maintenance in a hybrid can provide ROI in only a few years, with a huge benefit to the environment in the form of decreased emissions.
