Tidal turbines

Grader A: miss

Tidal stream power stayed at demonstration scale. Global cumulative tidal stream capacity was 41.2 MW in 2022, against more than 3,000 GW of global power capacity, far below 5% of new generation in any market by 2020.

Test: Industry share: tidal stream capacity 41.2 MW globally (2022), a negligible share of power generation capacity.

• Ocean Energy Key trends and statistics 2022 (Ocean Energy Europe) (2023-03): Global cumulative installed tidal stream capacity 41.2 MW in 2022, 30.2 MW in Europe.

Grader B: miss

Tidal stream turbines stayed at demonstration and pilot scale. European tidal farms generated about 60 GWh cumulative by 2020; the US had no commercial tidal plant. Tidal energy is a negligible share of electricity generation through 2020.

Test: 20% of relevant industry: tidal power well under 0.1% of global electricity generation in 2020

• Tidal power - U.S. Energy Information Administration (2024): No commercially operating tidal plants in the US; largest plants worldwide are 254 MW and 240 MW barrages.
• Tidal Energy | PNNL (2023): Tidal energy contributes a negligible fraction of global energy; most technology still early commercialization.
