Critical Minerals at Sea: Battery Supply Chains Become an Investment Question
Batteries have become a practical part of maritime decarbonization. They are used on ferries, harbor craft, tugs, offshore support vessels, crew transfer vessels, various types of remotely operated vessels, and hybrid ships to reduce fuel burn, provide spinning reserve, support dynamic positioning, enable peak shaving, and allow zero-emission operation in port. As of mid-2026, 156 different maritime battery systems from 118 manufacturing companies are commercially available.

Autonomy Offshore: Uncrewed Systems Move from Trials to Critical Operations
When maritime autonomy is discussed, the image is often a large cargo ship crossing an ocean without a crew. That remains a longer-term regulatory and technical challenge. The more immediate commercial market is developing elsewhere – smaller uncrewed surface vessels (USVs) and autonomous underwater vehicles (AUVs) are already surveying seabeds, inspecting pipelines and cables, monitoring offshore wind farms…

Batteries at Sea: Not All-Electric, Not Everywhere but Increasingly Essential
For much of the maritime industry, the energy transition has been discussed in terms of alternative fuels – primarily LNG, methanol, ammonia, or hydrogen. Batteries have often been treated as a narrow tool for limited-purpose vessels, such as water taxis and harbor craft. That view is becoming too constrained.The importance of batteries comes not from technology enthusiasm alone. Global shipping accounts for roughly 3% of planet-warming emissions.

Floating Nuclear: A New Offshore Energy Frontier
For decades, floating nuclear power occupied a niche position in the energy debate – technically feasible, strategically intriguing, but commercially marginal. Today, however, combined pressures of decarbonization, energy security, land constraints, rising electricity demand and water scarcity are making floating nuclear power a more serious proposition for policymakers, utilities, and infrastructureFloating Nuclear offers a potential source of reliable…
