Safety & Security

Objectives

• Risk management for the test facility at the design stage
• Roadmap for further development for later stages
• Meet the requirements of the Austrian authorities for the test facility
• Development of an risk management methodology to be employed for related high-pressure air storage technologies

Approval procedure

• Underground installations in EU are subject to approval
• No EU-wide regulation exists
• National regulations must be satisfied
• Location of planned test facility: Eisenerz, Austria
• Coordination with Austrian authorities is required

Risk assessment and risk management

• During the state-of-the-art approach similar projects were reviewed.
  • CAES power plants: Huntorf (GE)
  • McIntosh (USA)
  • ADELE (GE)
  • Airlight Energy/ALACAES (CH)

• High-pressure natural gas storage rock caverns
• Large-scale heat storage in process industry
• The qualitative risk assessment approach is based on the ISO 31000 risk management.

Methodology

Approaches from nuclear industry are adapted for RICAS2020:

• Widely accepted methodology exists
• Probabilistic Safety Analysis (PSA)
• Quantitative Risk Analysis (QRA)

ALARP principle (As Low As Reasonably Possible) is used to narrow the appropriate risk analysis approach:
