Nedavno je predstavljena nova tehnologija kojom bi se moglo iskorištavati energiju mora, odnosno energiju plime i oseke. Rije? je o ure?aju naziva Deep Green, ?ija se ispitivanja do mogu?e komercijalizacije provode u irskom Strangford Lough. Ure?aj Deep Green dizajnirao je Magnus Landberg, a razvija ga švedska kompanija Minesto, u suradnji sa kompanijama BGA Invest, Midroc New Technology, Saab Group i sveu?ilištem Chalmers University of Technology. Rije? je o ure?aju koji na vrlo jednostavan na?in energiju plime i oseke pretvara u elektri?nu energiju, a ?iji je princip rada, i sam dizajn, vrlo sli?an kiteu za iskorištavanje energije vjetra. Ure?aj se sastoji od krila i agregata, te je usidren na morsko dno; prolaskom vode kroz hidrodiami?ko krilo stvara se potisak koji omogu?ava ure?aju kretanje kroz vodu što rezultira rotacijom agregata i stvaranjem elektri?ne energije.
Deep Green se pokre?e ve? pri brzinama struje od 1-2,5 m/s, što ga, za razliku od sli?nih postoje?ih ure?aja, ?ini iznimno financijski konkurentnim. Njegova ukupna težina iznosi sedam tona, što je daleko manje od konkurentnih ure?aja, a što omogu?ava upotrebu manjih brodova i kranova prilikom transporta do željene lokacije. Tijekom sije?nja 2013. godine Minesto je zapo?ela s ispitivanjem prototipa, koje se, djelomi?no financirano od strane švedske Agencije za energetiku, provodi u tunelu za ispitivanje u SSPA u Gothenburgu. Nakon toga, na lokaciji Strangford Lough, nastavljena su ispitivanja na moru koja ?e trajati slijede?e dvije godine. Prototip snage 3 kW za sada nije spojen na elektroenergetsku mrežu, no nakon prikupljanja i obrade svih podataka, slijede?e ljeto se o?ekuje postavljanje i spajanje ure?aja snage 500 kW. Kompanija o?ekuje da ?e sredinom 2015. godine, u fazi pedkomercijalizacije, biti u mogu?nosti postaviti ure?aj pune veli?ine koji ?e biti spojen na elektroenergetsku mrežu.
