Tidal techno-fix narrative obscures community ownership, grid injustice, and Indigenous ocean governance in UK coastal energy transition
Original framing: “Turning the tides: Could hidden sea power energise our coastal towns?” — BBC News - Science
Celtic maritime traditions (Welsh, Cornish, Scottish Gaelic, Irish) encoded tidal knowledge in place-names, fishing calendars, and oral navigation systems — e.g., the Welsh 'llanw' (tide) toponyms mapping energy-dense channels. This knowledge informed early tidal mill siting and modern resource mapping, yet no benefit-sharing or epistemic credit exists. The article's 'hidden sea power' framing erases that coastal communities have never seen tidal energy as hidden — it is lived, named, and governed through customary practice.
The BBC's 'hidden sea power' story performs a classic enclosure narrative: a lone engineer 'discovers' what coastal commons have governed for millennia, while the structural determinants of energy justice — Crown Estate seabed monopoly, grid connection apartheid, CfD auction rigging, and epistemic erasure of Celtic maritime knowledge — remain invisible.
David Mummery's generator is technologically real but systemically irrelevant without community ownership rights, grid access, and consent regimes rooted in kaitiakitanga/Netukulimk principles. The 1,000 medieval tidal mills were not 'hidden' — they were commons infrastructure. Their modern suppression is not a technology gap but a power structure: the same Crown Estate that enclosed seabed now leases it to corporations while community energy groups queue for grid connections that never come. True tidal transition requires not better turbines but better governance: seabed rematriation, grid justice, and planning veto for fishers and Gaelic communities. Until then, 'energising coastal towns' remains a mummer's play — masked extraction performing as salvation.
