Generating compressed air to service core energy requirements is a major cost for many industrial facilities in Ireland. It often demands as much as 30% of the total energy budget.

Even though it is one of the most inefficient and expensive means of transporting energy around a facility, it is widely used. Companies generally do not know how to approach the problem.


  • Help companies optimise the performance of their compressed-air systems
  • Gain understanding of the best available technology
  • Identify improvement projects
  • Realise the potential of heat recovery in compressed air

Members: 6 companies and 4 leading consultancy firms

Activities: SEAI commissioned one-day compressed-air audits at each company in order to review the system and offer verbal advice and information.


  • Company-specific reports with recommendations for energy savings
  • Project report and technical guide (see links below)

Opportunities identified

  • Potential savings of 16,142,225 kWh (equal to 12,332 tonnes CO2)
  • Aggregate savings of 30% if all projects implemented
  • Up to 50% savings possible in some cases
  • Payback periods of between 0 and 4 years
