Enabling the Energy Transition

The critical bridge to net zero

Kestrel is the critical bridge between today’s energy system and Ireland’s net-zero future.

By replacing lost system energy storage from retired coal/peat/oil assets, and enabling large-scale future hydrogen storage aligned with national policy, it provides the backbone infrastructure required to integrate renewables at scale and sustain a secure, reliable and decarbonised energy system.

Replaces Lost System Energy Storage

With coal/peat/oil assets retired, Ireland has lost essential in country storage capacity faster than clean replacements had been built. Kestrel restores system flexibility that is indispensable to a renewable-led grid.

  • Currently there is no strategic renewable gas storage to secure fuel for power generation during periods of low wind and solar
  • Kestrel restores this functionality without lock-in to oil/peat/coal or natural gas (as it can transition to green hydrogen or biomethane)
  • Provides a secure bridge during the transition to renewables

Why it matters?

You can’t build a renewable future without system stability.

Hydrogen-Ready Infrastructure

Kestrel is being engineered from day one for green hydrogen, making it a future-proof asset that evolves with Ireland’s offshore wind ambitions and avoids the stranded-asset risks facing other legacy infrastructure.

  • Fully aligned with National Hydrogen Strategy
  • Supports future green hydrogen from offshore wind
  • Designed to transition directly to hydrogen use without significant retrofit, avoiding stranded assets

Why it matters?

This is not “interim infrastructure”, it is tomorrow’s system, built today.

Scalable, Sustainable, Invisible

Offshore and underground, Kestrel provides the only multi-TWh long-duration storage solution capable of delivering the scale required for deep decarbonisation quietly, sustainably, and without community disruption.

  • Offshore, underground, and environmentally low-impact
  • Enables deep integration of renewables by storing surplus renewable energy
  • Complementary to battery and interconnection, but uniquely capable of multi-TWh storage

Why it matters?

Ireland’s transition needs scale, and only geological storage can deliver it.
