Don't tell the tree huggers about how they de-ice wind turbines, see Twitter post below (twitter-dot-com/lukelegate/status/1361149723072208896 if you don't see it below)....
The climatism web site is really full of s**t. I've followed through a number of their articles and they are either taken out of context or they take the wrong results from the publication. Remember the Koch brothers paid some deniers to prove that CC did not exist. Unfortunatly the hired guns had to deny the deniers. Tough break.

The crisis in Texas, blamed by the Governor on Green energy solutions, is turning out to be the fault of
1) An isolated Texan grid so the lone star state does not connect its grid to the rest of the world, so when it gets hit it gets hit bad 2) An underinvested-in grid so that the resilience of other grids is just not there when Texas needed it most 3) A significant number of gas and oil pipelines which are not protected from cold weather so valves froze closed. 4) A strong belief in individualism so "you are on your own" 5) Resulting in a strong cascade of failure due to (2) and (4)
to add to this, the water supply system also seems to have failed the state (so nothing to do with green energy)
Republicans continue to blame this on Biden's Green New Deal which has yet to get passed into law. Shades of Trump-stupidity continue.
I think the tree-huggers won this one.

I think your point 1) also relates to the Texan grid being isolated so that Texas (or at least the energy companies there) didn't have to submit to Federal regulations.
Whoops.

This paragraph leapt out to me from that article... "The ice also creates an hazardous environment for the maintenance workers, with tons of ice stuck on the turbine that can fall down at any time, or smaller lumps of ice flung from the tip of moving wings at 300 kilometers per hour. For added protection Skelleftea Kraft maintenance workers ride on armored vehicles when visiting wind sites in the winter."<parp>

Hydrogen straight out of the ground just like natural gas and oil is possible so be wary of investing in renewable projects where marketing says hydrogen isn't a viable competitive renewable because it will be too expensive to produce from methane or water. It is very early days but this has been known about for a decade and there could be very large quantities just about everywhere in the world.
Been a lot of hydrogen news recently including a town in the north of england trialling a hydrogen / methane mixture on existing pipes and boilers.

natural hydrogen will only ever be a small part of the market with a limit on availability (unless anyone actually knows how to find it in quantity).
Beware of investing in blue hydrogen, most of the CCS is BS and will be driven out of the market as CO2 taxes become more the norm.
Green H2 is the only real product and be a bit careful of uranium H2
Ineos is now investing in green hydrogen, when a money-grubber like Jim Ratcliffe starts investing you know where the bright money is see also the Bamford family

Or are they trying to avoid BEV investment? JCB do at least have some electric diggers at the bottom end of their range. www.jcb.com/en-gb/campaigns/etech-rangeIneos don't even have a mild-hybrid version of the vapourware Grenadier, despite it being off-the-shelf BMW mechanicals.

Yep the whole Grenadier project has been a game of brinkmanship negotiation because the man is that good at using other people's money to make him money
His Electrolysers come from an existing business so here he is using an existing asset he doesn't have to pay for and yet gets early dibs at zero-carbon steel (if such a thing existed).
Linde, on the other hand are sitting on a Electrolyser JV with ITM but so far have ordered enough electrolysers to replace 1/3000th of their total H2 production from grey h2.
JCB have some weak electrical diggers, but have decided that moving to Fuel Cells (where they have no technology advantage) makes no sense when they can move to burning H2 in their existing home built engines (sunk capital cost) even though the H2 usage will be somewhere like 35% efficient. Since a fuel cell would be roughly 60% efficient it is not becuase they care, but because they presently have the technology and the assets. I assume they will aquire a fuel cell advantage sometime in five years to switch to FC.

There's a lot of people put a lot of money into fuel cells in the 00s before moving to battery. What's changed?

Like all technology you need economies of scale to drive the cost benefits that accelerate the growth leading to a virtuous circle I've worked with amazing technology that never made it because the cash flow was not there. Cummins recently bought in a FC company (Hydrogenics) to drive the cash through the technology. JCB hasn't. What changed specifically was PayPal happened. Giving an autistic Engineer a tonne of cash who decided batteries were the way to go. The rest is Tesla.

I'm not sure why you'd need to produce the hydrogen in North Africa then ship it - wouldn't it just be easier and more efficient for Saharan solar electricity to be transmitted straight to Europe, then the hydrogen "produced" (electrolysed from air or water) locally to demand? Like a lot of things it probably comes down to efficiency (electrical losses) and cost. I started trying to do some math but the numbers are either too big or too small for a Sunday evening. With one set of numbers I tried (based on the National Grid and some guesses) it looked like all the power generated would be lost in the cables before it got anywhere close to the UK. There are things you can do to improve that efficiency (higher voltages and more/larger cables) so there are options to make it possible to transport electrical power over that distance, however I suspect transporting the gas might be as efficient and work out cheaper (at least in the short term).
wow
Just in

Out of interest who is going buy the Rivian IPO? I'm expecting at least a 25% lift in the first 24 hours.
(this is not advice, just an opinion)

I take it these shares are not available to us until they become tradeable on the IPO day ? What's your plan if the market is already 25% above IPO price when they become tradeable? Do you just pass?
Actually I just noticed the thread title, does this company use hydrogen fuel cells ?

PrimaryBid may give you immediate access to the IPO at original price They have cooperated with ii according to their website ii (or any broker) could decide not to take the shares but that is unlikely given the sort of company Rivian is.
