Hitachi Energy is at the forefront of the energy transition, collaborating with customers and partners to enable the sustainable energy future of the power grids. As the first big step forward, we have launched our EconiQ™ high-voltage portfolio to deliver exceptional environmental performance and to phase out SF6.
We welcome the EU’s new F-Gas regulation that tells us without a doubt that EconiQ™ is the way forward as the solution with the lowest carbon footprint in the world.
Just recently, we delivered SF6-free switchgear for 420 kV and will continue developing a complete SF6-free product portfolio at all voltage levels, capable of minimizing carbon footprint without compromising safety, reliability, or size.
Join us on our EconiQ journey to an SF6-free energy future!
