That's only true for CO2.
Burning hydrogen does release other emissions. Especially NOx
>Burning H2 does not produce carbon dioxide (CO2) emissions. >That is good news for the climate.
>However, hydrogen combustion produces other air emissions. And that scientific fact is the untold story in this aggressive industry plan, one that could turn green H2 into ghastly H2.
>The bad news is that H2 combustion can produce dangerously high levels of nitrogen oxide (NOx). Two European studies have found that burning hydrogen-enriched natural gas in an industrial setting can lead to NOx emissions up to six times that of methane (the most common element in natural gas mixes).[17],[18] There are numerous other studies in the scientific literature about the difficulties of controlling NOx emissions from H2 combustion in various industrial applications.[19],[20]
>Even the Trump Administration’s Department of Energy “Hydrogen Program Plan” identifies H2 combustion as a significant problem. It states that additional research is needed on a host of emissions control issues around H2 combustion. The point DOE makes is that at very low levels of H2 blending, the NOx emissions levels might be controllable. But at higher levels, it is not only difficult to control NOx emissions, but the technologies that have been developed to attempt to control those higher NOx levels remain unproven.[21] That research is years off.

But you do still get NOx emissions....

It really depends on what use case you have and where you mount it.
But you're right that you're absolutely not getting nameplate capacity out of it very often.

Sure, but like both WLTP ranges and the range mentioned in the original article. These 'ranges' should be taken with a grain of salt.
In reality they are significantly less than WLTP numbers.
Still no cars with actual ranges over 600km

If you Buy and EQS, don't expect to get WLTP numbers.
Based on real world ranges, the EPA estimates are much close to reality.

> Thorium reactors and newer designs are incredibly efficient
not where is counts. They aren't economically efficient (Expensive)
>I love renewables, I'm ready for them, however can they handle peak loads?
when enough are deployed, absolutley. There are plenty of countries where they already do.
>Can they keep a stable output 24/7?
Again, yes they can. Have a google of Costa Rica or Portugal.
>We have to store excess power to help during peak loads
Sure, we have to do that now too. Nuclear also requires you to o store excess power to help during peak loads because you can't economically operate them in a flexible manner.
>what technoligies exist that's cost efficient and as good or better than just running a few nuclear plants in a region?
Literally all of them. Have a look at some actual recent numbers. Even Residential Solar is now the same price as nuclear.
>Electrcity transmission for a country is complex and daunting and there's more to it than just "Plop some more turbines and solar panels".
Sure, that's a nice red herring. Let me spice it up:
Electricity transmission for a country is complex and daunting and there's more to it than just "Plop in some more nuclear plants".

Yes WLTP and EPA aren't the same thing.
They are very different methodologies.

>To overcome this issue, the research team succeeded in developing an anode-free battery in a commonly-used carbonate-based liquid electrolyte by adding an ion conductive substrate. The substrate not only forms an anode protective layer but also helps minimize the bulk expansion of the anode.
So there IS an anode, just not the typical kind?
There is just a bare anode current collector without anode materials? But the substrate protects it?

WLTP is always higher. EPA says EQS gets 563 km. Which is probably much closer to reality

Except the point of renewables is to replace coal and gas power plants with something much greener to help keep a strong stable power in the transmission lines.
Maybe you could list the ways you think new nuclear can do any of that better?

That's exactly the point. Nuclear also has these same issues and isn't really more reliable than cheaper power production.
So why would we pay more and wait longer to build it?
>All these stories aren't pointing at nuclear being unreliable,
Well that long list of nuclear plants in those links that are shut down currently can't be relied on to produce power at the moment. Call it what you will...

What exactly are you trying to say? We should all pay more for nuclear even though it obviously also has reliability issues? What are we paying extra for exactly?

> Europe is not a particularly windy nor sunny place, so it’s not a very good place for renewables.
"Europe" is actually a fantastic place for wind energy. Solar is mixed, because 'europe' is a large area. Southern Europe has quite good Solar potential.
Overall Europe is a pretty good place for renewables.
