The big islands like Aruba are not the only ones to need energy alternatives. Antigua and Barbuda are among the leeward islands in the West Indies, boasting white beaches, lush coral reefs and favorable sailing weather. Most of the 80,000 people who live in on the two islands are involved with entertaining visitors to the tropical paradise. Like all the other islands in the Caribbean Antigua and Barbuda are heavily reliant on imported fossil fuel to keep the island nation’s tourist trade humming.
In early 2019, the government of Antigua and Barbuda signed a memorandum of understanding with Sweden’s Minesto AB (7MN: FRA) to study an alternative tidal power technology. The United Nations is facilitating the study.
Minesto's tidal power solution called Deep Green takes a lesson from wind power. Instead of wind its is ocean current that drives the turbine. Built like a 'wing', Deep Green 'flies' under the water in an eight-shaped trajectory. The device is actually moving at a faster speed than the underwater current. This makes it possible to generate significant amounts of energy even from slow moving tidal currents. Consequently, Deep Green can be deployed in less hostile ocean environments, unlike some other tidal power solutions that must seek harsher, fast current location and then are bedeviled by maintenance issues.
