For Immediate Release

New Durham, NH - March 31, 2000 -- Zero Emissions Technology Inc. announced today that the company is changing its name to Powerspan Corp., reflecting the company's focus on next generation energy technology to serve the competitive power industry.

Powerspan's proprietary energy technology can be deployed in multiple sectors of the power industry, including coal, oil, and gas based power generation. Deregulation is unleashing competitive forces that will require power generators to rapidly adopt innovative, money-saving technologies. Investment decisions, no longer supported by rate base recovery, are now driven by return on investment. Powerspan's innovative solutions address these changing needs of the power industry.

According to Frank Alix, chief executive officer of Powerspan, "Due to the evolving nature of our proprietary energy technology and its potential for widespread application, the time has come to refine our name to more accurately reflect our company and its future direction. The name Powerspan emphasizes our focus on the competitive power industry and on innovative applications of our proprietary electrotechnology. Driven by information technology, the new energy economy runs on electricity. As a consequence, technology that provides for clean, high quality electric supply will be in increasing demand. Furthermore, technologies which use electricity to enhance productivity, or electrotechnologies, will enjoy rapid acceptance."

Powerspan began in 1994 as Zero Emissions Technology Inc. The company initially developed and manufactured proprietary modifications for power plants fueled by coal. These products decrease particulate emissions for a nominal cost and, in some cases, provide a return on investment.

Recognizing the growing challenge of providing clean, competitive power from existing generating plants, Powerspan next developed a cost-effective, multi-pollutant control technology for coal-fired power plants. The patented technology, called Electro-Catalytic Oxidation^TM (ECO), provides the functionality of four separate control technologies in a single integrated system and produces valuable byproducts that become the feedstock for other industrial processes. With costs that are a fraction of alternative technologies, ECO addresses the need for producing clean, competitive power from existing generating assets.

ECO technology was successfully demonstrated in a pilot facility operated in collaboration with FirstEnergy at its R. E. Burger Generating Station. Powerspan and FirstEnergy are now planning a $10.5 million commercial ECO installation for Spring 2001 at FirstEnergy's Eastlake Generating Station near Cleveland, Ohio.

Powerspan Corp. is engaged in the development and commercialization of innovative, proprietary energy technology for the global electric power industry. The company is a pioneer in building cost effective and timely solutions for the existing power generating base. Company research and development efforts focus on unique applications of its proprietary electrotechnology to air emission control and water disinfection. Powerspan offers technology solutions to address the competitive needs of the new energy economy.
