Rules (2024-08-30)

  1. This is an English-language community. Comments should be in English. Posts can link to non-English news sources when providing a full-text translation in the post description. Automated translations are fine, as long as they don't overly distort the content.
  2. No links to misinformation or commercial advertising. When you post outdated/historic articles, add the year of publication to the post title. Infographics must include a source and a year of creation; if possible, also provide a link to the source.
  3. Be kind to each other, and argue in good faith. Don't post direct insults nor disrespectful and condescending comments. Don't troll nor incite hatred. Don't look for novel argumentation strategies at Wikipedia's List of fallacies.
  4. No bigotry, sexism, racism, antisemitism, dehumanization of minorities, or glorification of National Socialism.
  5. Be the signal, not the noise: Strive to post insightful comments. Add "/s" when you're being sarcastic (and don't use it to break rule no. 3).
  6. If you link to paywalled information, please provide also a link to a freely available archived version. Alternatively, try to find a different source.
  7. Light-hearted content, memes, and posts about your European everyday belong in [email protected]. (They're cool, you should subscribe there too!)
  8. Don't evade bans. If we notice ban evasion, that will result in a permanent ban for all the accounts we can associate with you.
  9. No posts linking to speculative reporting about ongoing events with unclear backgrounds. Please wait at least 12 hours. (E.g., do not post breathless reporting on an ongoing terror attack.)

(This list may get expanded when necessary.)

We will use some leeway to decide whether to remove a comment.

If need be, there are also bans: 3 days for lighter offenses, 14 days for bigger offenses, and permanent bans for people who don't show any willingness to participate productively. If we think the ban reason is obvious, we may not specifically write to you.

If you want to protest a removal or ban, feel free to write privately to the mods: @[email protected], @[email protected], or @[email protected].

According to [the French company] Normandie Hydroliennes, the grant will accelerate the deployment of one of France’s first commercial-scale tidal energy pilot projects, advancing marine renewables in the country.

The project will install four Proteus Marine Renewables’ AR3000 horizontal-axis turbines in Normandy, delivering 34 GWh annually to the French grid by 2028, enough to power 15,000 homes. The tidal energy developer’s NH1 farm aligns with France’s 2030 renewable energy targets and broader energy transition strategy.

[...]

Normandie Hydroliennes expects 80% of the project’s construction value to be sourced domestically, creating 400 direct and indirect jobs in France.

UK-based tidal energy company Proteus Marine Renewables, a key technology partner, is supplying the four AR3000 turbines for the NH1 project. The company highlighted the importance of the EU funding.

[...]

In February, Proteus Marine Renewables installed a megawatt-scale tidal turbine in the Naru Strait, Japan, making it “the first to operate such devices in two countries”.

How reliable is the production of tidal energy? Is it intermittent in production like wind power?

Well it's extremely predictable - only dependent on cycles of the moon (and sun). In a specific location there are slack periods every six hours or so, but the phase of the waves shifts as you move along the coast a bit (not too far, on the scale of France) so these could be smoothed out by combining power from multiple locations.

Thanks to the lunar tides shifting 50 minutes every day, you'll have great weeks where you provide maximum power exactly on-peak, followed by terrible weeks where generate exactly off-peak.

But as you said, it's entirely predictable, which wind is only partially. You can tell years in advance when you'll produce more, something sun and wind can't do.
