EU’s LIFE program recognizes the potential of GE Renewable Energy’s g³ insulating and switching gas as an alternative toSF6 to help significantly cut global greenhouse gas emissions. This is the second GE g³ gas project to be co-funded by the EU within two years. New g³ gas 245 kV circuit-breaker will be scalable to other high-voltage levels across Europe’s electrical grids and help utilities get ready for stricter fluorinated (F)-gas regulations.
We have already published news about the EU helping the GE company with 420 kV SF6 free circuit breakers.
GE grid solution company award from the European Commission:
GE Renewable Energy’s Grid Solutions business (NYSE-GE) has been awarded €2.5 million through the European Commission’s LIFE climate action program to help fund the development of an SF₆free 245 kV g³ live tank circuit-breaker.
The new high voltage circuit breaker will rely on GE’s industry-leading g³ (pronounced “g”- cubed) gas technology to deliver the same high performance and compact dimensional footprint as a traditional SF₆ circuit-breaker.
The co-funding reflects the EU’s commitment to accelerate the decarbonization of Europe’s electrical grids and help them get ready for the EU’s stricter fluorinated (F)-gas regulation, which aims to cut F-gas emissions by two-thirds by 2030. GE’s g³ gas is a game-changing alternative to SF₆ – a potent greenhouse gas – with a global warming potential (GWP) that is about 99% less compared to SF₆.
The new GE air-insulated 245 kV g³ live tank circuit-breaker, which will be based on International Electrotechnical Commission (IEC) standards, is the second g³ gas project co-funded by the EU. In 2019, GE received funding for a g³ gas-insulated 420 kV circuit-breaker, also as part of the EU LIFE Program.
Technology officer at GE’s Grid Solutions talks about EU aid for SF6 free high voltage circuit breaker:
“The EU’s co-funding of a g³ 245 kV live tank circuit-breaker will help demonstrate the applicability of GE’s g³ gas for this commonly used voltage level by transmission operators around the world, as well as outdoor applications down to -30°C,” said Vera Silva, Chief Technology Officer at GE’s Grid Solutions. “The new g³ 245 kV live tank circuit-breakers, once ramped up together with 420 kV voltage level, will help avoid the addition of some 52,000 tons of CO₂ equivalent annually on to the European grid alone and more – as we expect other continents to adopt our g³ gas technology.”
GE’s Grid Solutions teams will work with several European partners on this second EU-funded g³ gas project, including Germany’s Leibniz Institute for Plasma Science and Technology, which will build a scientific database of g³ gas properties. Industrial partners will help optimize the environmental impact of the new circuit-breaker throughout its entire life cycle.
A recent EU Commission report concluded that fluoronitrile-based gas mixtures – such as g³ gas – may be the only insulating and switching gas alternative to SF₆ when space is a constraint, such as in urban areas. That’s because fluoronitrile-based gas products feature the same compactness and performance as traditional SF₆ equipment, unlike other SF₆-free solutions.
Today, 25 leading electrical utilities have already adopted GE’s g³ products for their high voltage networks, avoiding the addition of more than a million tons of CO₂ equivalent to the grid. That’s the equivalent of removing about 476,000 petrol cars from the road for one year.
GE’s g³ gas-insulated products are currently available for live tank circuit-breakers and gas-insulated substations (GIS) up to 145 kV, as well as gas-insulated lines (GIL) up to 420 kV.
