Industry conversations increasingly revolve around alternatives to SF₆, with C4 and C5 fluoroketones leading the debate. These gases promise significantly lower GWP while maintaining insulation performance. But are they truly “drop-in” solutions? Equipment compatibility, long-term stability, and cost remain open questions. Early pilot projects show promise, yet many utilities remain cautious. DILO’s approach—developing handling equipment that accommodates both SF₆ and new alternatives—acknowledges this uncertainty. Transition won’t happen overnight, but the shift is inevitable. The challenge lies in balancing environmental responsibility with reliability in power grids that demand zero compromise.
