Flexible Generation Plants

  • Zero emission fossil-fuel free peaking or baseload power (Green CAES ™)
  • The only technology able to convert power stations to CAES (Hydrogen 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
  • Co-location with output cables for major renewable generation or interconnectors reduces grid connection capital costs and grid access charges, and maximises revenues.
  • 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 renewables also enables the generator to avoid grid access charges on its output energy, storage to avoid them on charging energy and storage to avoid capital costs of grid connections

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
  • Co-location with renewables benefits grids by greatly reducing reinforcement and adding real inertia 24/7
  • Emissions-free (Adiabatic) Green 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.)
