Submission + - Trump quashes electrical energy development (whitehouse.gov)

dhartshorn writes: Foreign produced "bulk power" equipment is now effectively banned.

And the list of what constitutes such equipment is essentially everything used to make up the grid(s).

And on which we are heavily dependent upon foreign sources.

"The term “bulk-power system electric equipment” means items used in bulk-power system substations, control rooms, or power generating stations, including reactors; capacitors; substation transformers; utility-scale and other grid-connected inverters; battery energy storage systems; and uninterruptible power supply systems supporting critical infrastructure, current coupling capacitors, large generators, small generators, backup generators, substation voltage regulators, shunt capacitor equipment, automatic circuit reclosers, instrument transformers, coupling capacity voltage transformers, protective relaying, metering equipment, high voltage circuit breakers, generation turbines, industrial control systems (including remote terminal units, programmable logic controllers, and intelligent electronic devices), distributed control systems, and safety instrumented systems. In determining whether equipment is within the scope of this order, agencies also may consider associated software and firmware, remote access capabilities, lifecycle maintenance and update mechanisms, and other supply chain dependencies that could present an unacceptable risk to the bulk-power system. Items not included in the preceding list or that have broader application beyond the bulk-power system unrelated to the national security concerns identified in this order are outside the scope of this order."

If power is available at the home it's available at the substation.

And the substation will have all the spare power for its many distribution lines concentrated in one spot.

And probably better data access, too.

Now go up stream one more substation and see how much better it is than the first one.

Some ideas should die in committee.

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.
