I agree. To revert to the original question, the evidence that Energy Storage Ireland has sent to my office and submitted to the committee seems to show that industry is ready to invest but there are structures that have not caught up yet.

On the curtailment and dispatch down that we are constantly discussing, and given the energy costs that the public is paying for wasted renewables at the expense of imported fossil gas, are the witnesses of the opinion that battery energy storage systems, BESS, long-duration energy storage, LDES, lithium or any of the proposals from other countries would help us in bringing down the overall energy costs per kilowatt hour? Has a cost analysis been done by Energy Storage Ireland? There are multiple storage options and one of the larger ones, the gravity pump, was mentioned, but do the witnesses think that batteries are the best or are there other viable options, for example, the storage of carbon dioxide underground? What would be the best option?
