Ways to use CleanCAES and other LDES to reduce grid reinforcement for the energy transition by 2/3 or more while supporting the hydrogen economy, data centres / AI & clean industry
About
Cleanergi Ltd is developing large-scale long-duration energy storage of electricity and hydrogen, and its integration with renewables, electrolysis, electricity / hydrogen off-takers and electricity / hydrogen grids. It operates only at grid and infrastructure scale, for countries, regions and cities. These have the potential to benefit the energy transition greatly, around the world, a multi-$trillion market opportunity, are probably the biggest single steps towards making the energy transition affordable, reliable and resilient for all. In increasing value:
♦ CleanCAES™: The world’s most efficient, cost-effective, flexible and capable electricity storage, widely implementable globally. An innovative form of adiabatic Compressed Air Energy Storage (CAES), zero-emissions, buildable with standard technology, and validated by numerous multinational engineering firms. The market for this alone is over $1trn capex, $10trn p.a. opex, with huge benefits for grids and major users.
♦ CleanStart™: A configuration of CleanCAES which is the only storage technology that can deliver grid-scale Black Start without having to reserve operational capacity.
♦ Hydrogen Storage: The same or adjacent salt caverns used for the electricity storage are the only way to store massive amounts of hydrogen cost-effectively.
♦ CleanGrid™ Integration with Electricity Grids: Each new GW offshore wind requires (in the UK) over £3bn / $4bn investment in grid upgrades +10% p.a., growing fast. Integrating CleanCAES, renewables and grids offers more than twice the benefits of stand-alone storage.
♦ CleanPark™ Energy Parks: patent pending integration of CleanCAES with large users (especially the H2 economy) and/or the grid can double these benefits again, and even take renewables and industry entirely off-grid. This reduces costs and increases efficiency & plant life, while removing the greatest regulatory and commercial risks.

Energy cost reductions to industry, data centres and the hydrogen economy.
Applications
- Stand-alone balancing and ancillary services on the grid, with the ancillary services both as by-products of energy delivery and deliverable separately, these being either concurrent or at different times.
- CleanCAES standing between renewables and the grid, reducing grid connection size by 1/2 to 7/8, reducing reinforcement to mostly local; the {renewables+storage} can be dispatched and treated like a single power station, delivering all its services (and more) concurrently.
- CleanCAES standing between renewables and large energy consumers, taking them all wholly or partially (depending on configuration) off-grid, delivering ancillary services if partially, optimising the use of all other energy and products / feedstocks.
- Delivering Black Start to entire grid sections, able to start adjacent sections and major off-takers, much more cheaply than any other system because (uniquely) it does not have to reserve capacity from operational use in order to ensure that it is not in a discharged state when called upon.
- Methods and market designs for optimising the grid for long-term, whole-system considerations and so minimise its cost and maximise its reliability and resilience through the energy transition and beyond: a 2050 grid costing no more than the 2010 grid for consumers and taxpayers.
