ABB and BCG make the case for a return to direct-current power

AI computing, electrification and renewable generation are renewing interest in DC systems, but standards remain a barrier.

The story

ABB and Boston Consulting Group say rising demand from AI data centres, electrified transport and renewable generation is reviving the case for direct-current power systems.

Many modern sources and loads already operate internally on DC, while repeated conversion between alternating and direct current creates losses and equipment complexity. Wider adoption, however, requires common safety rules and interoperable components.

The most important signals will be commercial deployments at scale, open standards and evidence that lifecycle savings justify changes to familiar electrical architecture.

Many modern sources and loads already operate internally on DC, while repeated conversion between alternating and direct current creates losses and equipment complexity. Wider adoption, however, requires common safety rules and interoperable components.

What to watch

The most important signals will be commercial deployments at scale, open standards and evidence that lifecycle savings justify changes to familiar electrical architecture.
