The completion of a tunnel over a kilometer long is a significant milestone in the development of the Coire Glas pumped storage hydropower plant in the UK. This project, with an estimated cost of £100 million, is poised to nearly double the UK's existing electricity storage capacity. The proposed Coire Glas project at Loch Lochy in the Great Glen is expected to have an installed capacity of 1,300 megawatts (MW) and can provide 30 gigawatt hours (GWh) of long-duration electricity storage, catering to renewable power needs for up to three million homes for a full day. Additionally, it is anticipated to become the largest hydropower energy site in the UK in the last four decades. The tunnel serves as a vital component towards the development of the underground powerhouse for the project, allowing the team to gather critical geological data for detailed design purposes. In a related development, Logan Energy, a green energy company based in Scotland, has secured a substantial hydrogen power deal to supply equipment for a fleet of zero-emission buses in the Czech Republic. The contract, touted as Logan's largest order to date, involves providing hydrogen production equipment powered by hydroelectricity for ten buses in Mníšek pod Brdy, south-west of Prague. This initiative represents a significant step towards sustainable public transportation in the Czech Republic.
