Environmental Technology Verification Report: Taconic Energy, Inc. TEA Fuel Additive


Hansen, T. Environmental Technology Verification Report: Taconic Energy, Inc. TEA Fuel Additive. U.S. Environmental Protection Agency, Washington, DC, 2013.


The U.S. Environmental Protection Agency (EPA) has created the Environmental Technology Verification (ETV) program to facilitate the deployment of innovative or improved environmental technologies through performance verification and dissemination of information. The goal of the ETV program is to further environmental protection by accelerating the acceptance and use of improved and cost-effective technologies. ETV seeks to achieve this goal by providing high-quality, peer-reviewed data on technology performance to those involved in the purchase, design, distribution, financing, permitting, and use of environmental technologies.


The Greenhouse Gas Technology Center (GHG Center) is one of six verification organizations operating under EPA’s ETV program. One sector of significant interest to GHG Center stakeholders is transportation - particularly technologies that result in fuel economy improvements. Taconic Energy (Taconic) developed the TEA fuel additive for gasoline passenger vehicles and requested that the GHG Center independently verify its performance. The GHG Center verified the fuel economy performance attributable to the TEA additive in October 2010. According to Taconic, the additive typically improves fuel economy in passenger vehicles by 1-5% and provides associated emission reductions. The primary performance parameter for this technology was the fuel economy change due to TEA additive use. The GHG Center performed a series of controlled dynamometer tests on a representative vehicle. Once the fuel economy change was established, a percentage fuel savings was determined relative to the reference fuel. Data review and validation was conducted at three levels including the field team leader, the project manager, and the QA manager. Results of the analysis show that there was no statistically significant change in vehicle fuel economy between the baseline and additized fuels on the HwFET duty cycle.
