Equipment Scaling and Corrosion Costs

3 verified sources

Definition

In geothermal power generation, scaling from mineral deposits and corrosion from acidic brines reduce equipment lifespan, leading to unplanned downtime and high OPEX in Australia's hot rock EGS projects like Cooper Basin.

Key Findings

  • Financial Impact: AUD 200k-1M per MW capacity annually in maintenance and lost output; downtime losses 5-10% capacity (e.g., 107 MWth direct use sector)
  • Frequency: Ongoing, accelerated in high-heat flow areas (80-120 mW/m²)
  • Root Cause: Lack of advanced scale/corrosion inhibitors in early-stage EGS pilots with 4-5km deep wells and 215°C brines

Why This Matters

The Pitch: Geothermal players in Australia 🇦🇺 waste AUD 500k+ annually on scaling/corrosion maintenance per MW installed. Automation of prevention monitoring eliminates this risk.

Related Business Risks

WorkCover Claims from Corrosion Failures

AUD 20k-100k per claim + 20-50% premium increase; typical for high-risk energy sector

Brine Reinjection Clogging Costs

AUD 50,000-200,000/year per project in cleaning, filtration maintenance, and lost capacity (based on 7 projects avoiding severe issues via 25-100 micron filters at 2-10 bar pressures)

Reinjection-Induced Capacity Decline

10-30% reduction in injection rates leading to AUD 500,000+ annual revenue loss per MW capacity from downtime and suboptimal flows

Environmental Non-Reinjection Fines

AUD 50,000-500,000 per violation (EPA fines for wastewater mismanagement) + remediation costs

Capacity Factor Reporting Losses

AUD30-65/MWh lost revenue from unclaimed LGCs; potential 2-5% annual revenue leakage for eligible plants

AEMO Reporting Non-Compliance Fines

AUD5,000-50,000 per reporting breach; plus lost dispatch revenue from capacity under-reporting
