Tidal stream energy could theoretically supply more than 150 terawatt hours per annum globally. This represents a potential total global market of up to 50 gigawatts (GW) of generating capacity.
Tidal stream energy is a significant renewable energy source because, although it varies, the power output is highly predictable. As a result, it can help to balance supply and demand as part of a balanced energy mix alongside other renewable sources such as wind and solar power.
The technology is still maturing but has made a further step towards commercial viability following the most comprehensive lifecycle assessment to-date of a megawatt-scale array. The assessment, authored by Black & Veatch’s UK marine energy team, shares lessons learnt during the planning, design, delivery and initial operation of MeyGen’s Phase 1A 6-megawatt (MW) array in Scotland’s Pentland Firth.
