Are underwater turbines the answer to how to harness the power of tides?
It certainly looks a lot less disruptive than the full scale tabla power plans/proposals for the Severn Estuary & Morecambe Bay.
Will be interested in what you make of this technology?

“Engineers off Scotland’s coast have deployed a groundbreaking tidal turbine touted as the world’s most powerful, capable of churning out 2 megawatts of steady, predictable electricity.”
It looks though as if batteries weren't included as part of the deployment to even out power supply which seems “peculiar”.

"“If the decision is to go ahead with adopting more and more AI – which I am surprised is not being questioned more at a time of climate emergency – then it is going to be better with a #renewableenergy source,” said Barfield."

Fascinating talk in Stromness last night - much of it on #windpower and Big Finance; how do local communities gain any value? Came away wanting to understand apparent under-funding of locally developed #wavepower and (non-barrage) #tidalpower. Any thoughts? #Orkney #Shetland @fionaorkneynews or @theferret

@fcalva Are you kidding? There's #solar, #geothermal, #windpower, #TidalPower, etc., etc. All of those should be developed over gas and oil. Also, NO NUKES FOR AI AND DATACENTERS! Seriously!!! AI and Datacenters are SUCKING UP way more energy than day-to-day living!

@asiny Wow, #tidalpower finally gets real? Unconvinced by europesays image, and let's make #renewables #replacefossilpower, not simply add.
But back to this story: ecological impacts and materials/engineering issues have always been key problem areas; obviously company website isn’t going to divulge!
Hivemind, feed my curiosity...

Electric 'superhighway' approved between #Scotland and #England
"The project will be the first of four #subsea electricity links planned along the east coast with the eventual capacity capable of powering 7.5 million homes."
August 13, 2024
by Kevin Keane"A multi-billion pound subsea cable that can shift vast amounts of #renewable electricity between Scotland and England has been given the go-ahead by regulators.
"#SSENTransmission says the #EnergyTransferProject is needed to move energy around the grid on days when the wind doesn’t blow or demand is high.
"The two 315-mile (507km) cables will run from Peterhead in Aberdeenshire to Drax in North Yorkshire and will initially work alongside a similar link down the west coast.
"It is part of wider moves to modernise and increase capacity on the energy transmission network for the shift away from #Fossilfuels to tackle #ClimateChange.

@silasmariner And nuclear plants are NOT equipped to handle temperature rise or storm surge from #ClimateChange. Get rid of #AI and #Cryptocurrency, build SOLAR where it's sunny (like the desert), and use #Geothermal, #Wind, and #TidalPower where appropriate. It's a bit of a no-brainer, if you ask me. Why not use what we have? And also be frugal with the ENERGY we do produce -- rather than waste it on Crypto and AI!

Japan nuclear watchdog halts Tsuruga reactor safety assessment again
KYODO NEWS KYODO NEWS - Apr 5, 2023
"Nuclear regulators said Wednesday they will again halt a safety assessment of an offline central Japan reactor after its operator repeatedly submitted documents containing errors, further prolonging a process toward resumption that has already taken years.
"Japan Atomic Power Co. has been seeking approval to reboot the No.2 unit at the #Tsuruga plant in #Fukui Prefecture under stricter regulations imposed following the 2011 #Fukushima #NuclearPowerPlant disaster, but its application has been fraught with mistakes and #DataTampering.
"The Nuclear Regulation Authority considered forcing the operator to withdraw its safety review application, but it ended up deciding on another suspension, citing how restarting the process all over the again would only burden the regulator.
"While public concern over the safety of nuclear facilities lingers following the Fukushima disaster, triggered by a massive quake and tsunami, the government is pushing the use of nuclear power as part of efforts to secure a stable electricity supply amid the war in Ukraine.
"Among the more than 30 existing nuclear reactors in Japan, 10 have resumed operations after clearing the post-Fukushima disaster safety hurdles, while 10 are still under examination by the nuclear watchdog, according to government data.
"The Tsuruga nuclear power plant is a two-unit complex, with the No. 1 reactor set to be scrapped. Japan Atomic Power submitted the safety review application for the No. 2 unit in 2015.
"In 2019, the nuclear regulators found over 1,000 inaccuracies in the documents submitted for measures against #earthquakes and #tsunamis, followed by revelations in February 2020 that the operator had rewritten data analyzing a drilling survey conducted on an area below the Tsuruga complex premises without approval.
"After a two-year suspension of the safety review, assessments restarted but they have remained at a virtual standstill as the regulators discovered errors in the locations given for geological features over the past months.
"In quake-prone #Japan, building #NuclearPlants or other important facilities directly above active faults is prohibited.
"Geological experts for the Nuclear Regulation Authority previously stated that a fault running underneath the No. 2 reactor was active, although #JapanAtomicPower has rejected the claims."

#Japan Is Building Underwater #TidalPower Plants on Ocean Currents
Innovation & Technology / By Bojan Stojkovski / June 15, 2022
"Active shipping around the Japanese islands does not allow the Japanese to deploy conventional tidal power plants, and therefore Japanese experts are now developing and testing underwater power plants immersed in water to a depth of more than 50 meters.
"Successful testing of early prototypes of such power plants leads to Japan’s plans to build extensive networks of 2-MW standard tidal turbines by 2030.
"The development of the Kairyu Tidal Ocean Power Plant was started by IHI and NEDO scientists in 2011. By 2017, the partners assembled a 100 kW unit in the form of three 20-m floats with two 11-m blades (two 50 kW generators).
"The immersion depth of 50 meters was chosen for safety reasons during #typhoons, when you will not surprise anyone with the 20th wave, although the closer to the surface, the more influential the movement of water masses.
"The most promising place for installing underwater tidal turbines near Japan is the Japan Current (#Kuroshio) area off the country’s southern and eastern coasts in the Pacific Ocean. The potential current power is estimated at #205GW.
"IHI and NEDO are planning to build a 2MW tidal power plant with 40 blades for commercial use. A distributed network of such turbines could significantly contribute to providing the islands with electrical energy.
"According to Japanese experts, this type of network could generate electricity at the price of #solar energy. At the same time, the efficiency of tidal power plants is much higher than that of solar farms.
"Thus, the installed capacity utilization factor (ICUF) for solar farms is only 15%, while for tidal power plants, it reaches 70% and approaches the ICUU of thermal power plants with 80%.
"After the accident at the #Fukushima #nuclear power plant, Japan has problems with developing a peaceful atom. Also, there are no areas for full-fledged solar energy in the country, and the #winds are not as predictable as in Europe. Tidal power plants could be the foundation in Japan around which the government will build #carbonfree energy."

#California regulators vote to extend #DiabloCanyon nuclear plant operations through 2030
California energy regulators have voted to allow the #DiabloCanyonNuclearPlant to operate for an additional five years, despite calls from #environmental groups to shut it down
AP, December 14, 2023,
SAN LUIS OBISPO, Calif. -- “California energy regulators voted Thursday to allow the Diablo Canyon nuclear plant to operate for an additional five years, despite calls from environmental groups to shut it down.
“The California Public Utilities Commission agreed to extend the shutdown date for the state's last functioning nuclear power facility through 2030 instead of closing it in 2025 as previously agreed.
“Separately, the federal Nuclear Regulatory Commission will consider whether to extend the plant’s operating licenses.
“The twin reactors, located midway between #LosAngeles and #SanFrancisco began operating in the mid-1980s. They supply up to 9% of the state’s electricity on any given day.“The Public Utilities Commission's decision marks the latest development in a long fight over the operation and safety of the plant, which sits on a bluff above the #PacificOcean.
“In August, a state judge rejected a lawsuit filed by #FriendsOfTheEarth that sought to block Pacific Gas & Electric, which operates the plant, from seeking to extend its operating life.
“And in October, the Nuclear Regulatory Commission rejected a request from #environmental groups to immediately shut down one of two reactors.
"PG&E agreed in 2016 to shutter the plant by 2025, but at the direction of the state changed course and now intends to seek a longer operating run for the plant, which doesn't produce greenhouse gases that can contribute to climate change.
“Democratic Gov. Gavin Newsom, who once was a leading voice to close the plant, said last year that Diablo Canyon’s power is needed beyond 2025 to ward off possible blackouts as California transitions to solar and other renewable energy sources.
“#Activists condemned the extension and noted that the projected #costs of continuing to run the aging plant are expected to top $6 billion.
“’This ill-conceived decision will further escalate financial strain on California ratepayers and extend the threat of a catastrophe at Diablo Canyon,' said #KenCook, president of the nonprofit #EnvironmentalWorkingGroup.
'With California’s annual #RenewableEnergy additions exceeding Diablo Canyon’s output, there is zero reason to keep it running,' he added in a statement.”
