Comment Dwarfing, yet far less useful (Score 3, Interesting) 37

"The planned battery would dwarf a 19 GW lithium-ion project in the UAE..."

Iron-air batteries have a 0.01C charge/discharge rate.

The reason 300MW has 30GWH of storage is because of that.

The cost per kWh (capacity) is frequently touted as the reason for their use, but in fact, you're paying for storage you'll rarely (if ever) use. Yes, it will sustain a four day outage, then potentially be exhausted the next day because it takes nearly six days to recharge (using the 0.7 efficiency). And while getting there, 60GWH of energy will be lost as waste heat.

LFP can have a C rate up to 10. 1 to 3 is common, So 100 to 1,000 times faster charge/discharge. Stack the energy behind the inverter that you actually need and spend less in the long run, both CAPEX and OPEX.

Then stack as many cells as you need to get the duration desired.

It's at least 4X faster, cheaper and vastly more comfortable than 24 hours in a train seat.

Given the time needed for construction, some decades faster, as well. Long enough to fully develop synthetic aviation fuel.

If you look at typical HSR routes, they are only a few hours long. All of Japans high speed rail wouldn't make it LA to NYC.

Comment Yet the gaslighting for fossil fuels continues (Score 1) 130

Sites like 'The CO2 Coalition' are putting out "news" and "analysis" that portrays RE/net zero as harmful to developing nations, proposing that it will cause starvation and worse. Only fossil fuels with that ever so helpful addition of CO2 to the atmosphere is moral.

Meanwhile solar initiatives like this (and some wind) are leapfrogging traditional infrastructure just like cell phones did for both telephony and network access. And with battery prices falling through the floor, there is no practical limit.
