The difference is a solar farm consists of 4 million identical modules and a quarter billion identical cells. If a cell is faulty, it decreases output of that module by 2%. If a module is faulty it either decreases the string output by 5% o

Yes. The capacity factor is a blatant lie given that units 1 & 2 are about 60%, and the costs are an old estimate of overnight cost without escalation or inflation. Comparing overnight costs to final all-in prices is one way nukebros lo

The USA quotes AC capacity, costs and power. So a 100MW plant in the US quoted at $110 million including the cost of finance, profit margin, regulatory compliance, insurance and transmission with a capacity factor of 27% has 130MW DC of mod

You're amortising the cost over a time period that is in direct contradiction to reality, at an EAF that is in direct contradiction to reality at a cost of capital that doesn't reflect the likelihood of project failure or early cl

You see, that's the greenwashing bit. It's not made from water, it's made from fossil gas. All these schemes to increase demand aren't about making electrolysers to replace existing grey hydrogen, they're ahout sell

Hydrogen has a GWP of 11. Cube square law also makes small scale hydrogen storage more expensive than batteries. Then you're back to limited niche uses, or needing expensive, leaky distribution. The best use of hydrogen for seasonal ar

Very nice attempt at gaslighting, but claiming it's "partially spent fuel" and that calling it waste is a lie is like claiming shit is "partially eaten food" because you can still see a couple of corn kernels. It&#x

You are attempting to insinuate that reprocessing will eliminate the nuclear waste and obviate mining new U235. It does neither. Stupid semantic games and motte and bailey rhetorical techniques do not change this.

Yes. You could have done that rather than comparing to a ship two orders of magnitude larger. That wouldn't have been a ridiculous attempt to mislead.

The relevance is that fertile material is not "partially spent fuel" in any extant fuel cycle. First it does nothing to the fission products (which are the bulk of the radioactive waste by mass). Second turning U238, Pu240, Am241,

Also false. LNG carriers are volume limited. Hence Q-Max vessels carrying about 100,000 tonnes vs bulk carriers of similar length carrying 400,000 tonnes. Also I said useful energy. Depending on application, electricity is 1.5-5x as useful

Answering the original question, it's about 10-20x as much usable energy for the oil. So if there's a wind farm 5% of the distance than an oil farm, the cost of the ship part is a wash.

Oil is much more energy dense. Using current gen batteries, this is a cargo of about 1200t for 240MWh Oil would be 13000MWh of chemical energy. Or a replacement for 2000-7000MWh of electricity. It would never be worth transporting electrici

The much higher capacity 8000 gross tonne hydrogen carrier can deliver about 1400MWh, after spending 3000MWh filling it up with a bunch of electrolysers then liquifying the hydrogen which you'd have to build a floating platform for.

There is lead too in some, but even if it all somehow teleported out of the module and directly into the soil (as opposed to this never happening) it would be 10% as much as was already in the soil naturally before leaded gasoline was a thi
