AI Ocean Thermal Energy
AI systems for ocean thermal energy conversion optimization
The Problem
“Optimize Ocean Thermal Energy sites with AI-driven energy autonomy for EV charging and battery storage”
Organizations face these key challenges:
OTEC generation efficiency varies with ocean temperature differential and auxiliary system performance
EV charging demand is uncertain and can create sharp load spikes
Battery storage must balance autonomy, backup reserve, and degradation constraints
Manual scheduling cannot react fast enough to changing generation and load conditions
Weak-grid or islanded sites face strict reliability and power quality requirements
Data is fragmented across SCADA, BMS, EV chargers, meters, and weather/ocean monitoring systems
Operators lack decision support for multi-objective tradeoffs between cost, resilience, and autonomy
Impact When Solved
The Shift
Human Does
- •Review historical ocean conditions and seasonal performance assumptions for expected net output
- •Manually tune pump speeds, heat-exchanger targets, and operating setpoints during changing conditions
- •Schedule inspections and maintenance from fixed intervals and observed performance losses
- •Investigate output shortfalls and decide corrective actions after degradation becomes visible
Automation
- •No AI-driven forecasting or optimization used in routine operations
- •No continuous fusion of ocean, weather, and plant data for site-specific predictions
- •No automated early warning for fouling, pump inefficiency, or heat-exchanger drift
Human Does
- •Approve operating strategy and dispatch priorities based on forecasted net generation and availability
- •Review AI-flagged anomalies and decide maintenance timing, vessel use, and outage windows
- •Authorize setpoint changes outside approved operating limits or during unusual ocean conditions
AI Handles
- •Forecast thermal gradient, intake temperatures, currents, and expected net power at site level
- •Continuously optimize pump loading, heat-exchanger targets, and working-fluid setpoints to maximize net output
- •Monitor equipment and process signals to detect fouling, degradation, and emerging failure patterns early
- •Prioritize maintenance actions and operating exceptions by impact on availability, auxiliary load, and net generation
Operating Intelligence
How AI Ocean Thermal Energy runs once it is live
AI runs the first three steps autonomously.
Humans own every decision.
The system gets smarter each cycle.
Who is in control at each step
Each column marks the operating owner for that step. AI-led actions sit above the divider, human decisions and feedback loops sit below it.

Human lead
Approval, override, feedback
AI handles assembly, analysis, and execution. The human gate sits at the decision point. Every cycle refines future recommendations.
The Loop
6 steps
Assemble Context
Combine the relevant records, signals, and constraints.
Analyze
Evaluate options, risk, and likely outcomes.
Recommend
Present a ranked recommendation with supporting rationale.
Human Decision
A human accepts, edits, or rejects the recommendation.
