Diagram: Offshore Wind + Geothermal Hybrid Offshore Renewable Hybrid – Wind, Geothermal & Hydrogen Offshore wind generates power → subsea cables to platform → electrolysis for green hydrogen → geothermal heat extraction → export via repurposed/new pipelines. Source: Adapted from IRENA / Sustainability Magazine concepts.
1. Offshore Wind – Record GrowthGlobal offshore wind capacity exceeds 100 GW by end-2026, with 30–35 GW added annually.
- Floating wind matures (e.g., Hywind Tampen).
- Turbines reach 15–20 MW.
- Subsea cable demand surges (HVDC export + array cables).
Subsea relevance: Cable burial, protection, and monitoring use pipeline techniques (ROV/AUV, trenching, CP)
2. Geothermal – EGS Scaling Rapidly
Enhanced Geothermal Systems (EGS) unlock base load power anywhere using O&G drilling/fracking.
- Fervo Cape Station (Utah): 100 MW Phase I online 2026 → 500 MW by 2028.
- Utah FORGE: 2–3× faster drilling.
Subsea potential: Offshore geothermal could use insulated flowlines and tiebacks.
3. Hybrid Systems & Synergies
Offshore wind powers subsea electrolysis for green hydrogen; geothermal provides firm heat/power. Repurposed O&G pipelines support CO₂/hydrogen export.
Renewables integrate with existing offshore infrastructure subsea skills are increasingly valuable.
