Despite its advantages, the adoption of DC infrastructure is not without technical challenges. Chief among these is the absence of zero-crossing in DC voltage waveforms, which precludes the use of conventional AC circuit interruption strategies. Faults in a DC system persist unless addressed by advanced protection mechanisms such as solid-state circuit breakers or ultrafast fusing elements.

High-voltage DC faults pose significant operational hazards—particularly in confined indoor environments. While system design can limit fault current magnitude, the consequences of a fault event remain severe without rapid disconnection. Implementing robust protection requires a sophisticated coordination strategy and often introduces additional capital cost and engineering complexity.

Nevertheless, analogous systems in the marine and rail sectors demonstrate the feasibility of these solutions. The growing maturity of solid-state protection devices and modular breaker designs is enabling safer, more reliable high-voltage DC deployments. As demand for DC-centric infrastructure rises, emerging standards and an expanding ecosystem are beginning to fill the historical gap. In parallel, untapped innovations—whether in academic labs or government research institutions—present opportunities for differentiated solutions. While protection remains a key consideration, it is no longer a showstopper, but rather an engineering frontier ripe for refinement and deployment.
