The world's most cost-effective and efficient large-scale long-duration electricity & hydrogen storage, making the entire electricity and H2 sectors more cost-effective & efficient
About
The world's most cost-effective large-scale long-duration electricity storage, hydrogen storage and related integrated projects, head-and-shoulders ahead of all competition. Enormous synergies for green integrated projects, the more integrated the better, mostly built around Storelectric's Green CAESTM, including: - Halving grid connection size for offshore wind, saving ~£0.5bn/GW wind, increasing the quality and value of electricity sold (reducing by ~2/3 for onshore wind; ~3/4-to-7/8for solar); - Enabling renewables to power electrolysis, fuel synthesis, chemical synthesis, iron and steel making and other major uses more efficiently, cost-effectively, extending plant life, potentially entirely off-grid and therefore much more cheaply and cleanly; - Powering other infrastructure-scale plants such as desalination, water treatment with renewables much more efficiently and cost-effectively. Enabling renewables to power the world affordably, reliably and resiliently.
Key Benefits
1. CAES replaces power stations in providing many grid services including balancing intermittent renewable generation, eliminating their emissions and reducing cost to grid / consumers of the energy transition. 2. Cheaper, more efficient (grid-to-grid, whole-life) and more capable than any other technology (pumped hydro is a little more efficient but much more expensive, remote and has few potential locations). 3. Delivers concurrently the capabilities of 4-6 batteries of the same size. 4. Delivers services that cost the UK grid £8bn p.a. more in 2021-22 than just 3 years before, avoiding such increases. 5. Enables grid connections of renewables to be halved or better (each new GW offshore wind requires £3bn grid reinforcement, which we can halve or much better at the cost of £0.5bn). 6. The only way currently available to store massive amounts of hydrogen cost-effectively. 7. Enables renewables to power electrolysis, electricity-consuming and hydrogen-consuming industries to be powered solely by renewable energy, often eliminating the electricity grid connection with its costs and regulatory issues. 8. Probably the biggest single step towards green hydrogen achieving cost-parity with blue and grey hydrogen, eliminating their emissions and on-costs. 9. Profitable without subsidy in today's markets in some countries; becoming more so. 10. Major synergies with renewable generation, grids, the hydrogen economy, infrastructure developers and others. 11. An unparalleled potential for financiers to deploy immense funds in geographically and technically diverse investments globally, into a key infrastructure industry. 12. Leading the development of a new global industry with global need, market and growth potential.
Applications
1. Enables renewables to power electricity grids affordably, reliably and resiliently, cutting costs and improving quality. 2. Delivers not just balancing services but also stability, ancillary, power quality and Black Start services, concurrently with the same capacity. 3. Reduces capex and opex of renewable generation. 4. Avoids grid reinforcement costing £billions per GW new renewables. 5. Enables electricity-consuming industries (e.g. water treatment, desalination, nitrogen fixing) to be powered exclusively from renewables and potentially taken off-grid. 6. Makes electrolysis and hydrogen-consuming industries (e.g. ammonia / methanol synthesis, iron, steel) to be powered exclusively from renewables and potentially taken off-grid. 7. Enables large island-grids to be powered renewably, e.g. Timbuctoo, 2000 miles from the nearest grid connection. 8. Enhancing profitability and utilisation of interconnectors. 9. Supporting the decarbonisation of other industries (heating, transportation, industry etc.). 10. Currently suited to globally-distributed salt basins; in future will also use other geologies which have been identified and which we will develop.
