We’re excited to announce a new partnership with DoD’s Environmental Security Technology Certification Program (ESTCP) to further demonstrate and validate ARPA-E derived technologies at DoD installations across the country. ESTCP targets DoD’s urgent environmental and installation energy needs to improve Defense readiness, resilience and costs. Projects under this partnership will conduct demonstrations to validate the performance and operational costs of promising ARPA-E technologies and provide valuable data needed for end-user acceptance and to accelerate the transition of these technologies to commercial use.

Leakage from SF6-insulated circuit breakers and power equipment has been raising environmental concerns due to the high GWP of SF6. Georgia Tech proposes TESLA, an SF6-free high-voltage circuit breaker. Recent breakthroughs in the dielectric properties of supercritical fluid research show the promise of using it as a dielectric and arc-quenching medium for high-voltage AC circuit breakers instead of SF6. TESLA opens possibilities for an SF6-free electric apparatus.

GE Grid Solutions plans to develop a SF6-free high-voltage AC outdoor dead-tank power circuit breaker. The circuit breaker will be rated at 245 kV and will also provide the basis for a two-break 550 kV rated design. It will use g3 TM gas mixture for current breaking and dielectric withstand. This project is a critical step in launching a range of products that meet U.S. energy industry requirements without using SF6 technology. These products are essential to reduce the bulk electric system’s carbon footprint and greenhouse gas emissions.

The University of Connecticut proposes to develop a life-cycle management framework to accelerate and safeguard the transition of the U.S. power grid toward a sulfur hexafluoride (SF6)-free green power network. Although SF6 has several positive properties, it also has a global warming potential (GWP) 25,200 times that of CO2. Studies suggest the alternative environmentally friendly gas mixture g3TM as a promising potential replacement for SF6.
