Goal to Eliminate Carbon Emissions
Siemens Energy and Mitsubishi Electric will research methods to expand the application of clean air insulation technology for higher voltages. To eliminate emissions, they will begin with a 245 kV dead-tank circuit breaker, which will accelerate the availability of climate-neutral high-voltage switching solutions for customers around the world. Both partners will continue to independently manufacture, sell, and maintain distribution panel solutions.
In most substations around the world, sulfur hexafluoride is the most potent greenhouse gas, with a global warming potential about 23,500 times greater than carbon dioxide. Even with very low leakage rates, the impact on global warming is significant.

In the direction of eliminating carbon emissions, the demand for alternatives is growing as operators seek future-proof technologies that significantly reduce the carbon footprint of their systems. At the same time, regulations to reduce or ban the use of fluorinated gases in the electric industry are being reviewed and implemented in various parts of the world.
The Commitment of Siemens Energy and Mitsubishi Electric
Siemens Energy and Mitsubishi Electric are pioneers in developing high-voltage switching solutions. Both companies have been working on developing insulated switching solutions, utilizing sulfur hexafluoride, which replace greenhouse gases with clean air, a pure mixture of nitrogen and oxygen, in order to contribute to global carbon neutrality goals.
So far, clean air insulation is the only alternative to greenhouse gases and thus poses zero risks to health and safety. Together with vacuum circuit breakers, superior performance for switching applications is guaranteed, even compared to all known sulfur hexafluoride circuit breakers.

The Norwegian Equinor has presented a plan showing that it will accelerate investments in renewable energy and low-carbon solutions as new oil and gas projects come online, before reaching peak production in 2026, the company said on Tuesday, under pressure to prove it can adapt to a greener future.
Equinor stated that it will dedicate more than 50% of its investments to renewable energy and carbon capture by 2030, up from less than 5% in 2020, meeting the demands of investors and some Norwegian politicians.
