This demonstration proves viability of blended fuel operations with existing equipment, aligning with CPV’s larger decarbonisation goals of reducing carbon emissions, operational flexibility, and further diversifying environmentally responsible energy generation.
The test utilised the facility’s GE Vernova 7HA.01 combustion turbine, operating at base load while burning 5% by volume of the hydrogen-natural gas fuel mix for the one-hour duration of the demonstration. As a result of its success, this test highlights the ability to adapt conventional combined-cycle technologies in the ever-changing power generation space.
“At CPV, we are constantly evaluating technologies and processes to modernise our existing generation portfolio and development pipeline,” said Sherman Knight, CEO of CPV. “The recent demonstration at CPV Towantic took several years of collaboration and planning to support a safe, well-designed test coordinated by our team, industry partners, and the State of Connecticut. We now have key information to better understand the technical and operational considerations involved in potential large scale applications.”
“We’re proud to support CPV and our partners in exploring hydrogen as a potential pathway to lower emissions while maintaining the reliability customers depend on,” commented Dave Ross, CEO of GE Vernova’s Gas Power business in the Americas. “The successful operation of the 7HA.01 gas turbine on a hydrogen-natural gas blend demonstrates how existing power generation technologies can adapt to support evolving energy needs.”
GE Vernova provided technical support throughout the process and onsite during the test. Certarus served as the hydrogen fuel supplier, with Burns & McDonnell leading engineering oversight of both design and studies ahead of the test. NAES Corporation, the operations and maintenance provider for CPV Towantic, oversaw plant operations during the demonstration and supported implementation of safety protocols.
While undergoing a rigorous analysis to evaluate the plant’s existing design and suitability for the project, CPV worked closely with Connecticut’s Siting Council, as well as the Department of Energy and Environmental Protection (CT-DEEP) to receive approval for a modification of the plant’s existing air permit allowing for the burning of hydrogen up to 5% by volume.
CPV Towantic Energy Center has been in operation since May 2018, providing safe, reliable, cost-effective power for Connecticut.
