Hybrid-Electric Tugboat:

Why This Matters

Ports are the heartbeat of our economy:

Critical for supply chains, national defense, and local communities. Yet most tugboats still run on outdated diesel engines.
With this partnership, the industry takes a massive leap forward:

• Over 4,000 HP per tug powered by Arc’s vertically integrated electric drivetrain
• 6 megawatt-hour battery buffer ensuring power and endurance
• Battery-dominant hybrid system with alternative fuel charging redundancy
• Competitive with diesel costs — without the emissions
