As electrification rapidly becomes the cornerstone of the energy transition, it brings with it immense opportunities — but also unavoidable challenges. The move toward electricity as our primary energy source is accelerating across sectors, and for industry in particular, this transformation is both promising and problematic.
You have likely already encountered the well-known hurdles: grid constraints, volatile electricity prices, and fluctuating availability. But there is another, less-discussed issue looming in the background — one that directly impacts reliability and long-term resilience: grid stability. With more generators, transformers, and consumers connecting to alternating current (AC) grids, we are seeing an increase in disturbances — voltage dips, waveform glitches, and faults — that compromise reliability and may even shorten the lifespan of critical industrial equipment. These are not minor annoyances. They are systemic risks.
So, here is a question worth asking: Could direct current (DC) offer a better way forward?
It is a provocative thought. After all, we have built our entire electrical infrastructure around AC for over a century. But DC has some compelling advantages — particularly in an electrified industrial landscape. By maintaining constant voltage, DC has the potential to reduce grid congestion, eliminate waveform interference, and improve overall efficiency. Think about what this could mean:
- Fewer transformers
- less copper usage
- Shorter implementation timelines
- Greater compatibility with DC-native technologies, such as electrolysers, battery storage systems, and data centers
Of course, transitioning to DC is not without its own technical and regulatory challenges. Safety, standardization, and interoperability remain open questions. But that is exactly why the conversation must begin now.
ISPT and Stichting Gelijkspanning Nederland are taking the lead — bringing experts together to explore the promise and limitations of DC infrastructure.
The future of energy is electric. But the future of electricity? That’s still up for debate.
