Evaluating Mechanical Strength in Vertical-Axis Tidal Turbines: A Comparative Study of Internal Blade Structure and Material Selection through CFD Simulation [PDF]

E3S Web of Conferences
Due to the density of water, tidal turbine blades are subject to significantly greater stresses than wind turbine blades. Multiple blade failures occurred during prototype testing as a result of loading conditions and protracted exposure to seawater ...

Life Cycle Environmental Impacts and Socio‐Economic Implications of Tidal Electricity Generation and Storage in the UK

Advanced Sustainable Systems, Volume 10, Issue 6, June 2026.
If tidal electricity generation and storage replaced natural gas and battery storage by 2050, it could reduce the climate change impact of UK grid electricity by 71%, saving up to 4.4 Mt CO2 eq./y. Most other environmental impacts would be reduced by up to 24%. However, high costs and low public acceptability hinder its deployment. ABSTRACT Tidal range
