Why OTEC is a great alternative to power offshore operations

1. Reliable Baseload Power at Sea

Unlike solar or wind, which are intermittent, OTEC can operate 24/7, throughout the whole year. That’s because the tropical ocean provides a consistent thermal gradient, allowing for uninterrupted power generation. This makes OTEC a dependable source of baseload electricity, essential for offshore operations that require constant power for drilling platforms, processing facilities, aquaculture systems, or autonomous installations.

2. Proximity to the Resource

OTEC thrives in tropical waters where surface temperatures exceed 25°C and deep water stays around 4°C. Offshore operations in these regions are often located directly above this ideal thermal environment. That means energy can be generated on-site, reducing or eliminating the need for costly fuel transport or long undersea power cables from land.

3. Fuel-Free and Emissions-Free

OTEC uses the ocean’s natural thermal energy and does not rely on fossil fuels. This significantly reduces carbon emissions, helping offshore operators meet stricter environmental regulations and ESG targets. By switching to OTEC, companies can decarbonise their offshore energy supply while protecting fragile marine ecosystems.

4. Energy Independence and Resilience

Many offshore platforms rely on diesel generators, which are vulnerable to fuel supply chain disruptions and price volatility. OTEC removes this dependency by providing energy security and operational resilience. For floating or remote installations, this can mean fewer risks, lower OPEX, and greater autonomy.

5. Integration with Other Offshore Infrastructure

OTEC systems can be designed to integrate directly with floating platforms, subsea installations, or even co-located with aquaculture and hydrogen production. Modular designs make it easier to scale the power output as operational needs grow.
