#Tidal Power’s Fickle Future

To pull power from the waves, you need a high tidal range or strong currents. Sea level rise threatens to mess with both.

by Doug Johnson, April 17, 2023

- For tidal power generation, location is everything. To produce energy, tidal generators need fast currents or a sizable swing in sea level between high tide and low tide.

- A site’s currents and tidal range, and its potential for tidal power generation, is a complex consequence of myriad factors, including the basin’s width, length, and shape, the inflow from rivers, and the height of the sea. It’s this last variable—sea level—that threatens to throw a wrench in the world’s tidal power plans.

- Sea level rise is 'going to displace, eliminate, or create new optimal sites across the system'

- Right now, tidal energy is far from being a massive part of the world’s energy mix. But the field is growing, and as it does, it could be difficult to pick out ideal locations for turbines—particularly those that stay ideal long term.

- There should be more investment in making smaller, transportable tidal energy operations. 'Otherwise, it’s going to be a big capital investment wasted.'

[CNBC] - #Energy company announces world first as its tidal power project hits major milestone.

The emerging #TidalPower sector seems to have taken another step forward — an Edinburgh-headquartered firm said Monday that its project had achieved a world first by producing 50 gigawatt hours of #electricity.

Fascinating article about #TidalPower from #TimeMagazine in July.
“A rising tide lifts all the grids”

“The idea is simple. First, tides. They rise and fall predictably, relentlessly driven by the gravitational pull of the moon. Those traits combined make the tide an attractive proposition for powering the grid. ‘The sun doesn’t always shine; the wind doesn’t always blow,’ notes Simon Forrest, the CEO of Scotland-based tidal-power producer Nova Innovation. But with tidal, he says, ‘we can tell you how much we will be generating two minutes past 3 in the morning a month from now, five years from now.’”

' ... look at all the remunerative things they won’t do because they’re short of money, my dear roads and canals and Channel Tunnels and harnessing the tides, because my dear there’s no doubt that coal is too obsolete, and gosh you’d think there was enough water in this country to run the universe by electricity ...'

Written in 1929, nearly a century ago, and we're STILL not running the universe by hydroelectricity.
