These things are dangerous and baeries are getting cheaper.

This is all a lie produces radiation ambition is just propaganda AI is stupid

Nice, thanks! All those cyclers, what are they doing if it's really bad weather? cold/snow/rain? I like and actually do use my bike in my town, but only when the weather is "nice". And I really do pity cyclists that have to ride in shitty weather..

Paul Burgess on UA-cam shows the actual reality of the tidal power claims! He has provided a link to his video in the comments under @climate realism!

This video totally refutes the claims in this video ua-cam.com/video/W9UTilAGSqQ/v-deo.html

Nicely done!

Very interesting luke.....I have a big interest in the River Mersey I live a 1/4 mile from it in Runcorn. I would miss the natural flow of the River In And Out Twice A Day.....but its a price worth paying. Very nicely and well presented.

This tidal stream crap is a stupid concession to environmentalists. There should be a concrete dam across the whole width to be able to harness the full available energy and storage potential.

Its extremely simple to know the real facts..kust place spectrometer at the top of each stack..within a few hours you'll know exactly what's coming out of those chimneys..😂

What are the “environmental consequences”, of burning trillions of tonnes of fossil fuels, or creating tens of thousands of tonnes of highly radioactive nuclear waste! The bigger picture…..

Flywheel Storage - Total BS. The wheel stores next to NO energy at all. I've got a patent for a Perpetual Motion Machine. Any buyers ?

You can not store a gallon's worth of fuel based energy into a mechanical based storage device that will work for the residential market. Even 1kw of potential mechanical energy is pretty god damn scary to stand next to.

Drax is obscene. The politicians who approved this were at best very poorly advised. At worst corrupt.

Flywheel transfer energy into stress in the material! Not the best way to store energy! Pretty much everything is better, heat, pressure, chemistry, capacitors!

Tom Stanton been real quiet since this dropped

By adding carbon capture it doesn't become carbon neutral as Drax will sell the carbon credits to emitters and so Drax must still replant trees to reduce the carbon debt you mentioned

In Estonia large swaths of forests have been cut down in order to make wood pellets for countries like Denmark and the UK. In the meantime, the people making and selling these pellets have become immensely wealthy.

I appreciate the thoughtful and nuanced video compared to the "Just have a Think" video with the incredibly disingenuous "4x worse than coal" caption. The carbon debt is a legitimate issue, but there is a big difference between releasing CO2 from molecules that were sequestered 10-30 years ago vs those from 60 million years ago!

Ill be damjed. I thougjt this guys vouce was Ai. If i didnt hear the voice and see the face it was coming out of, i would have sworn it was an AI voice generator.

I think we can look at wood burning at Drax as a large-scale pilot scheme. If we hadn't done it, we'd have no idea how practical it was, or what regulation was required. We need experiments like this to help steer policy. Experiments that tell us what NOT to do are still valuable. It should only be considered a scam or failure if we learn nothing from it and build more of them without tightening up the regulations.

Instead of importing wood pellets from North America, instead we should have forestry on unproductive farmland here in the UK. It will provide local jobs, potentially in old and allow us to ensure that it's managed sustainably and help draw down carbon.

Biomass works if it's a waste stream that otherwise has to be dealt with. Sewage sludge, trash, corn cobs, rice hulls, sawmill offcuts and dust, etc. All of them could be converted to liquid fuels through direct hydrogenation, the Fischer-Tropsch process, or the Shell Methanol-to-Gasoline process.

And the goverment spends millions of our tax money on this scam 😢

Why keep saying BRITISH and BRITAINS when all reports say we pay a German company to run it?

gas and oil should strike lets see if renewables can keep us warm in the winter either way as a test

And as of today the UK has the most expensive electricity In the world, and we're spending billions on the great green con

Unless biomass is very short carbon cycle - a few years max - as far as climate is concerned it's a carbon fossil fuel. It's carbon fixed at a point in the past. And unless replanted at at least the same rate, it's all greenwash. The other factor is that wood has a higher specific co2 emission per kilowatt-hour. It's about 0.42kg/kWh. By comparison, the coal it previously burnt from local collieries was about 0.28kg/kwh. Overall I suspect we'd have been better off environmentally by continuing to burn local coal & offsetting that with rewilding projects whilst we ramp up genuinely low carbon power systems. There's also the social dimension that we shut down our own pits & exported the jobs, which also meant less energy security due to dependency on other countries, shipping etc.

Biomass = greenwashing. U.K. used to burn wood for fuel until all the trees in Britain were cut down, so then had to find a new fuel - coal. Now they want to go back to the future. Stoopid!

Most UK electricity generation comes from natural gas which is methane which is the most expensive, is a much more powerful greenhouse gas and do hard to sow that we only have one week's storage. The UK has no sunshine in Winter when electricity usage peaks. Drax, dropped coal and solves green energy intermittentcy when President Putin is trying to strangle Europe and China is still building coal fired power stations. We need governments to be pragmatic and protective but individuals can still be free to show virtuous leadership. You didn't mention the enormous Canadian old forest wildfires which burned and produced more Carbon Dioxide than two years of Worldwide fossil fuel burning!

"Old Growth" is NOT a carbon sink. it is at a stage were carbon is return to the "carbon Cycle"

Aie aie aie! Absolutely terrible. Just like the wood pellet plants in the nordic countries! Totally the opposite of sustainable. Accelerating the deforestation of what little is left of global old growth forests! Obviously a short term goal like net zero should come nowhere near justifying destroying anymore of our fragile and key ecosystems and habitats. That should be obvious.

They'd be better off burning the coal that the power station basically sits on top of

wood seems to me to be pre-fossil fuel. Same problem.

If you'd asked *any* decent engineer with a calculator in their hand they would have told you way back that biomass energy would never be 'green' or carbon neutral. So right now that same engineer would be telling you that nuclear is utterly unsustainable and damaging for the environment. In addition that engineer will tell you that outside of a very few edge cases, hydrogen as a fuel is plainly non-sensical.

Its quite evident school doesnt teach thremodynamics, mathematical logic or basic biology.

Fact is ...8 billion humans is 7 billion too many...this planet cannot sustain our hubris. Amazingly the " greenies" want MORE humans...just like e economists ..

Great video, good discussion on why the sustainability of biomass is not necessarily a straightforward question. I find discussion on renewable energy is easily manipulated by bad faith actors who just want to smear all of it in favour of fossil fuels so this kind of balanced information is really valuable. Personally I would be a bit anxious about carbon capture and storage too - I've only ever heard of it being proposed by fossil fuel companies and then massively failing to deliver.

The customers won't see any reduction in bills for cheaper energy. Any money saved will go to wealthy share holders no doubt.

Smells like a massive scam to me.

"can be recycled" is not the same as "will be recycled". I prefer solutions that use recycled, not just recyclable, materials.

what's the ROI compaired to solar panels?

Hi, do you have any data on the self-discharge rate when in stand-by? Thanks

I think it’s worth the environmental downsides. This is actually less invasive than a hydroelectric dam because water can flow freely between both sides most of the day. Allows for marine life and water type to constantly mix as if the tidal plant wasn’t there

Earth rotates and flywheels hate that, so gymbals and dynamos running at 90%, so 80% recovered. Hmm..same as a lead-acid battery. Let us assume your bearings hold, and nothing jars it.

A pointless endeavor!

Flywheels only make mild sense in zero G, and even that introduces some gyroscopic problems. This company is doomed, running off VC money, put in by people who don't understand what they are investing in. Magnets aren't free, degaussing is a long term problem. Also, 10kWh is pretty silly. That's $5k of LiFePo4 batteries with zero moving parts. I'd rather a shipping container sized nuclear reactor, preferably thorium based.

I think I have design improvements for flywheels. But I cant implement them.

Great video. Subscribed.

As I understand the physics, superconductor powered magnetic suspensions essentially have zero friction, so combined with adequate vacuum tech there might be an avenue for large scale long term capable power storage utilizing flywheels in the near future.

They failed export quality standards.
