The BBC published an interesting article about SF6, a gas used in electrical installations as an insulator and “fire suppressant.” This gas has been used for years in high-voltage switchgear. However, as we increasingly rely on electricity—whether as a substitute for gas or to power electric vehicles—we require more of it, including in wind turbines. Unfortunately, no installation is 100% leak-proof, and the impact of those leaks can be seen in the atmosphere. This is particularly concerning for a gas that is 23,000 times more potent than CO2 in warming the planet.
I’m seeing this issue arise in my current project as well. Should we opt for compact installations because land in Amsterdam is expensive, or should we avoid using this gas altogether? After all, the entire purpose of the energy transition is to reduce greenhouse gases. It’s a fascinating and challenging conflict of values!
