- The world’s oceans could play a role in supporting the clean energy grids of the future. But that possibility hinges on the successful rollout of tidal stream and wave technology. Tidal stream energy taps into the power of run-of-river or ocean movements, while wave energy generates electricity using windblown waves.
- Years of hype and failed projects have bedeviled the tidal stream industry, which is the more progressed of the two technologies. But with demonstration projects in the U.K. seeing success, momentum is now building toward commercialization.
- Tidal stream technology — using river mouth, seabed-mounted or floating turbines — could offer reliable renewable energy for island communities, cutting their current reliance on costly imported fossil fuels. But technological, environmental and supply chain hurdles remain on the path to scaling up.
- While tidal and wave power will never dominate the…
As tidal power rides a wave of clean energy optimism, pitfalls persist
