Has there ever been a successful hydrogen based project? There must be but I'm struggling to think of any. The Hindenburg worked for a while but it had a few issues in the end. Since then it's been downhill.
ALL EVs use battery cooling systems, cars, HGVs, Ships and planes. The Tesla Semi uses a 750kW charger for their 900kWh battery, supposedly good for 400 miles. 400 miles isn't niche, it's 8 hours driving. Mandatory rest breaks mean you'd need to be stopping somewhere around then anyway so you might as well charge.
Hydrogen HGVs have been looked at but they just don't work. There isn't the infrastructure and there never will be. Technically there's no reason they couldn't work, but they'd cost 16x as much as an EV and something like 4x what a diesel costs to run at the moment. It's economic insanity.
It always amazes me how many people talk about how things need to be tried to looked at without actually looking to see if they've been tried or looked at already.
SMRs aren't expected to be cheaper than large nuclear, ever. No one involved in them is making that claim, at least not before 2050. Their advantage would be quicker installation and potentially quicker planning but that'll only be after the first multi decade case gets past every objection under the sun.

Yes that was me - here is some more reading.I've been following up on this, posted on another thread. According to some reports, hydroelectric can release more greenhouse gases than fossil fuels. Especially in tropical climates, where most of the planned renewables will be hydro. It's a bit depressing!
Long considered a “clean” energy source, hydropower can actually be bad for climate - Energy Exchange
A new EDF study published this week in Environmental Science and Technology shows that hydropower — the leading renewable energy technology projected to grow rapidly — is not always as good for the climate as broadly assumed. Moreover, continuing to assume that it is could mean that projects...blogs.edf.org

Do you start to see now why some people are sceptical about the whole global boiling narrative and have questions - they are not climate deniers - flat earthers and the rest of the tropes but people with eyes open asking questions and not just swallowing what their government tells them - especially when the doom is followed by needing to tax you more to save the planet.

The world experienced its hottest April on record, continuing an 11-month streak of unprecedented high temperatures, the European Union’s climate change monitoring service has said. April was 1.58 degrees Celsius (2.84 degrees Fahrenheit) warmer than an estimate for the same month in the 1850-1900 pre-industrial period, C3S said. While there are temperature variations associated with natural cycles such as El Nino, “the extra energy trapped into the ocean and the atmosphere by increasing concentrations of greenhouse gases will keep pushing the global temperature towards new records”, said C3S director Carlo Buontempo.
Eastern Europe and most of Africa particularly heated up in April, C3S said, backing reports of record heatwaves that forced schools to shutter in South Sudan and saw countries like Slovakia record their highest daytime temperatures above 30C (86F) in spring. Parts of South and Southeast Asia, from Bangladesh to Vietnam, were struck by scorching heatwaves, while southern Brazil, the United Arab Emirates, and the East African countries of Kenya and Tanzania have suffered deadly flooding. Pakistan recorded double the normal monthly rainfall in April, making it the country’s wettest month in more than 60 years. Much of Europe witnessed a wetter-than-usual April but southern Spain, Italy, and the Western Balkans were drier than average, C3S reported.
Average sea surface temperatures were also unusually high, breaking records in April for the 13th consecutive month, despite the weakening El Nino, the agency said.

Most people have more sense than to swallow what deniers tell them.
Yes, then we pointed out that they are now being recycled.
An excellent post if I say so myself.

Enva launches wind turbine blade recycling service
Enva launches wind turbine recycling service that crushes and shreds turbine blades to enable the recovery of recyclables, such as steel.

You quote it like the whole blade is being recycled when in fact most of its volume is being burned !.Enva launches wind turbine blade recycling service

Split up, last i heard. Their guitarist will be at Cropredy with F.port Convention and i think the drummer's in rehab. Again. A fine folk-rock band in their day.

Solutions are being developed, that's the way things work.
DecomBlades’ breakthrough in recycling wind turbine blades » Energy Cluster Denmark
New results from the DecomBlades innovation project proofs that glass fibre retrieved from wind turbine blades can be processed and melted to high-quality fibre qualifying to be used in new wind turbine blades. Proving this way of using recovered glass fibres is a real breakthrough on the path...

I believe you are conflating different things here. That's what often makes it so difficult to have a decent (or honest) discussion with many people on the denial/deflection side of the debate. I think it always helps to go back to basics. Separate out the question of whether global warming is happening, from what we actually do about it.
The basic principles of the science are straightforward. Greenhouse gases absorb long wave infra red radiation and this causes them to heat up. The earth radiates long wave infra red radiation. Human activity has massively increased the amount of greenhouse gases in the atmosphere. Greenhouse gases in the atmosphere absorb this radiation and heat up. This is causing the earth to warm up. Is there anything there you disagree with?
What we do about it is another issue and an extremely difficult one. If some of the planned solutions such as burning wood and hydroelectric are really just fiddling the figures then they are pointless. But that just means we need to come up with better solutions. It doesn't make the problem go away.
