Dude, this isn't warped in any sense. It's been long known (though not widely) that even through renewable sources, 1kg of hydrogen would require 9 litres of water and some 52-56kWh of electricity. 40kWh is said to be under perfect calculable yield. The Honda Clarity and Toyota Mirai consumer roughly 60 miles per kg of hydrogen gas. That's woeful economy given most [electric] cars can travel that 60 miles with around 15 kWh. It's one of the first stumbling blocks for hydrogen, but everyone was made to believe in them since the early 2000s/ The controversy between hydrogen and battery electrics goes back a long way, back when CARB was sued and ordered to relax on its position on electrics in favour of hydrogen - back in 2003. Careful who you call to be twisting facts and reality, Spectre

R.B. Accent, man. And also being Irish I can sympathise. This is crazy here. I'm being thrown into a whirlpool of panic and dawning... Have I been saying cars like that all the time?

Jacek Jagosz Look up what a Hydrogen vehicle is made up of under the skin. They still have some batteries as back up power for fuel cell, like in a hybrid, they currently max at around 80kW, they often have way more material too.

Union of Concerned Scientists does a yearly or so report on the emissions impact of gasoline, hybrid, plug-in hybrid and electric vehicles and compares them. Hydrogen is sold in such low numbers, and have only existed as compliance cars that not much info has been made. Besides, the average number (two or three Toyota, Honda and Hyundai) hydrogen cars being built now isn't the best to do gather data from. They're normally heavy with a lot more material than plug-ins. They're normally more larger sized vehicles, more powerful to compensate, but not exactly faster. Driving economy on electric (battery miles per kWh) for a Hydrogen vehicle is considered to be at 3 mi/kWh or less.

Yurt

FINALLY! It took us maybe 9 years BUT WE FINALLY SAID THIS Real Engineering, would you've amybe used TransportEvolved, GreenCarReportsm InsideEVs and others on YouTube and else where online for research?

Wonder if Brian is gonna do a CinemaSins take on Gibbs' Planet of the Humans?

Ain't that right, Buster?

I'm surprised you didn't talk about Dublin. Highest restriction for new buildings are 28m.

It's a market solution to the markets' causes? The west does it again!

What's up with the Euro NCAP tests, Brian?

Will this video ever change the tone and attitude of the nuclear argument on the r/Ireland sub? I hope so. Great breakdown, Brian, great shtuff.

Hey Brian, is there worth seeing the technology of NiMH batteries? Traditionally they're more reliable and practically serviceable unlike sealed Li-ion batteries, but they lack the nominal voltage for scale (previous 28kWh packs used to weigh 600kg). The materials to make NiMH cells aren't as problematic or scarce as they are to Lithium. You might know in the 2000s Ovonics chemistries who patented the technology for automotive use was sold by GM to Texaco, then Texaco was bought by Chevron. Ovonics restructured into Cobasys halted all mass manufactured cells and sued manufacturers like Panasonic and Toyota for years until settling in 2004 that cells of 25 Amp-hours or less were freely allowed to be manufactured by others. However, automotive cells of 50 - 98 Amp-hours were completely restricted (hence who killed the electric car) and 10 years of electric automotive development was lost. The patents expired in 2016, but Cobasys sold to A123 in 2009 were long gone. While they weren't high performance by any means, it's a wonder how that technology were mass produced with energy densities that rival today's technology. Is looking into NiMH worth exploring for heavy machinery such as rail, farming or plug-in assisted hybrid use?

Nuclear also costs the same to build a d produces the same amount of zero waste

@MattyEngland bankers or bosses? One of those dichotomies which has an anti Semitic legacy.

10:33 tell that to BMW 's i3. Maybe profitability is close to their chest, but the CFRP tubs were cold pressed, made from hemp fibres and brought much lower co2 manufacturing emissoins compared to traditionally aluminum and steel car bodies.

When are we gonna get past/dismiss the commercial market hurdle and get this into public use?

The ability for electric cars (built 10 years ago) have the built in ability to charge during grid lows at night, and to export during grid demand highs at 5pm. Provided, that existing Vehicle To Grid chargers are installed

@therealctoo4183 The joke bait that fossil fuel subsidies entertain is that it helps to maintain domestic jobs and keep the retail prices low at the pump - both incredibly political topics.

Micheal Moore and Gibbs should've really watched this of Real Engineering's first.

Why also not do that during the middle of the night where most grid efficiency is lost? That's kinda the idea the EU is treating with hydrogen storage.

Wonderful work putting Dublin's stresses into the world-wide limelight, Brian! It seems to be the only thing that sends a kicking message to our governments.

@DavidHRyall worth it, and crucial. Misinformation and (science) illiteracy thrives on the internet.

ok....

12:51 Ahh, kinda disappointing with the weasel words. Fair, you can say that it is outside your realm, as an engineer. But as a human being who can see these material demands, needs and powers can surely see that there is one big driving force behind child labour in mines and global underpaid work, the ever growing extraction of materials, the growing waste and carbon pollution driving climate change. All have one hegemonic driver that kept humans in roughly the last 100 years consuming and growing economically at rates to avoid bankruptcy/unemployment. A sociopolitical and historically important one at that. Y'know brian

Are you just more interesting in a hit for China?
