Hitachi ABB and GE sign agreement to reduce environmental impact in electrical transmission industry

Hitachi ABB and GE sign agreement to reduce environmental impact in electrical transmission industry
.

The companies have entered into a non-exclusive, cross-licensing agreement that will allow them to expand their range of high-voltage equipment using a game-changing gas alternative to SF6.

Hitachi ABB Power Grids Ltd and GE Renewable Energy’s Grid Solutions business recently announced a non-exclusive, cross-licensing agreement related to the use of an alternative gas to sulphur hexafluoride (SF6) used in high voltage equipment. This fluoronitrile-based gas mixture has a significantly reduced impact on the environment compared to SF6.

Under this landmark agreement both companies will share complementary intellectual property related to their respective SF6-free solutions. This will help accelerate the use of fluoronitrile-based eco-efficient insulation and switching gas in high-voltage equipment as an alternative to SF6. A recent EU Commission report concluded that fluorinitrile-based gas mixtures may be the only insulating and switching gas alternative to SF6 when space is a constraint.

For almost half a century, SF6 gas has been the norm in the electrical power transmission and distribution industry due to its unique physical properties. It is, however, a greenhouse gas that contributes to global warming if leaked. For this reason, Hitachi ABB Power Grids and GE have been investing in the development of better alternatives to SF6.

The agreement paves the way for a standard SF6-free solution for high-voltage equipment in the coming years. This would enable utilities and industries to accelerate their reduction of greenhouse gas emissions while facilitating their ability to plan as well as operate and maintain their networks thanks to standardized services and the use of the same auxiliary equipment.

“As part of our commitment towards a carbon-neutral future and accelerating the energy transition, we  have chosen to work towards a standard solution to address the needs of our customers through this cross-licensing agreement,” said Markus Heimbach, Managing Director of the High Voltage Products business in Hitachi ABB Power Grids. “As a technology leader, we have always been at the frontier of gas-insulated switchgear (GIS) that became a key enabler for urbanisation and installed the very first SF6-free GIS that significantly reduces carbon footprint,” he added. 

Heiner Markhoff, CEO of GE’s Grid Solutions said, “Utilities are becoming increasingly aware of their environmental footprint and the impact it has on their communities and the world around them. Today’s landmark agreement reinforces our commitment to help our customers to reduce their greenhouse gas emissions. GE pioneered this fluoronitrile-based gas which we named g3 and subsequently developed a broad SF6-free product range. Our g3 SF6-free products have been commercially available since 2015 and feature the same compactness and performance as traditional SF6 equipment.”

The two companies will keep the product development, manufacturing, sales, marketing and service activities of their gas solutions fully independent. Each company will continue to independently grant and set terms of licences to its respective intellectual property, hence preserving supplier base diversity for the industry and fair competition.
