Flexible Generation Plants

  • Zero emission fossil-fuel free peaking or baseload power (TES CAES)
  • The only technology able to convert power stations to CAES (CCGT CAES)
  • Bulk energy storage 20MW to multi-GW power, and 4 hours to multi-day duration
  • Maximized flexibility providing load shifting, grid balancing, ancillary services and T&D deferral solutions
  • 24-hour voltage support, emergency power, black start, and power quality conditioning
  • Allows the replacement of fossil fuel generation with low cost renewable energy, cutting or eliminating emissions
  • Also flexible consumption, providing Demand Turn-Up and related balancing services

Optimising Wind and Solar

  • Renewable energy on demand at a lower cost than diesel / OCGT power
  • Time shift generation to maximise project economics and provide risk mitigation during triads
  • Eliminate curtailment of low marginal cost renewable energy at times of low demand
  • Baseload or peaking plant designs sized to cover peak demand periods
  • Electrical independence for islands, micro-grids, and off-grid locations
  • Co-location with output cables for major renewable generation or interconnectors reduces grid connection capital costs and grid access charges, and maximises revenues.

Grid Investment Deferral

  • New transmission and distribution lines, substation capacity and other assets have long lead time, are expensive, and challenging to permit
  • Maximise existing T&D capacity by utilising capacity bringing power through transmission bottlenecks to charge during off-peak times
  • During peak demand times, inject electricity from storage after the T&D bottleneck, to supply market on the load side
  • Emissions-free TES (Adiabatic) CAES can be installed in densely populated urban areas as it uses no hazardous substances
  • Provides flexible generation and reliable back-up power for critical areas and infrastructure

Asset Repurposing

  • Repurpose existing coal plants by leveraging location and existing infrastructure
  • Re-purpose existing CCGT/OCGT by leveraging location and existing infrastructure
  • Such re-purposing gives new life to otherwise stranded assets by adding revenue streams, reducing emissions and (as price volatility increases) reducing operational costs
  • Co location of storage with renewable generators allows better use of under-utilised T&D infrastructure
  • Repurposing existing salt caverns currently used for natural gas storage for improved economics
  • Repurposing of other underground storage assets such as aquifers, depleted hydrocarbon fields, disused mines, porous inclusions.

Optimising the Electricity System

Profitable in today’s market, without subsidy, provided it operates on a level regulatory playing field
Enables the de-carbonising of the grid, and assists the de-carbonisation of fossil fuels for heating, transportation and industry, without subsidy
Enables local / regional / national generation to provide for local / regional / national needs, thereby improving energy security

Sir David Attenborough states categorically to Barack Obama, with supportive response from the American president, “If we find ways of generating AND STORING power [his emphasis] from renewable resources, we will make the problem … disappear”. This was when Obama interviewed Attenborough 28th June 2015. (This is the Guardian’s cut-down version, to save time viewing the full 35 minutes.)
