So, naive questions: Why does China build so much coal power capacity, instead of nuclear? I know they have nuclear plants under construction, so why the mix? Why not just one kind of power generation, whichever is cheaper for them?

From what I understand, it is t least partly due to their own assessment on how quickly the institutional knowledge can be increased to the scale required. Slapping down a few dozen reactors to 1960's French spec over a decade or so is one thing, throwing down hundreds of gen 2 reactors in half the time is quite another. The capacity for design, construction, parts procurement and operations personnel at such a consistently high QAQC standard that was not expected in the 60's and 70's is no mean feat. China kills thousands of coal workers a year and that is the price of doing business - the CCP can't afford for nuclear accidents potentially impacting Beijing to be normalized. Maybe as they gain confidence in the ability to cookie cutter the plants and support services, they might lean more and more heavily in that direction but for the CCP to survive, they need to expand the electricity network to a program that requires building out coal now.

Also, I have started assembling knowledge on local providers for battery storage (as well as reputable suppliers like ABB) for assessing the potential here - going to be a slow process I am sure but will update as we receive the proposals - at the very least it is a good learning experience for one of my local grad engineers.

I would love to see those sorts of prices as well. We utilize HFO sets for power and run an extra one just for redundancy - hurting fuel efficiency and running up maintenance hours. I have organized PLC/SCADA gurus to implement a powerstation wide SCADA control linked into the process plant SCADA so that load shedding can be implemented such that large loads such as a 4MW mill can be dropped off in the event of a generator trip but obviously that comes with process interruption and wear and tear costs.
Instead of load shedding, if 4MW could be provided for 20 mins, it would give enough time to run up another generator in the event of a power trip and also allow for the generators to be operated all the way up to 100% average continuous power output (with the battery being the spinning reserve).

Is there a rule of thumb for how much power output Li ion can give for a given amount of storage? eg, does 4 mWh of storage allow for 2 mW instantaneous output (and therefore I have to capex 8 mMh @ $800/kWh = $6.4 million to achieve 4 mW spinning reserve). If wiring it up so I only need just the absolute storage and the cheaper price it means 1.35 mWh @ $100/kwh = $135k so pretty much a no brainer.

A decent rule of thumb is you can discharge at about 3x the installed capacity. So a 1 MWh install can discharge at 3 MW. This is a little reductive since it depends on the size of a base battery cell, how many cells you have, and the size and quantity of inverters. But for the commercially available grid-scale systems that I have worked with its about right. I am sure you can mess with the storage size vs discharge rate if you get into designing something custom.

A project I am currently working on is 550 kWh and 1,600 kW. Cost for the system was about $600,000. This doesn't include installation and permitting and utility interconnect approvals/costs.

For reference I am an Industrial Controls Engineer that works for a firm that designs and (sometimes) installs power plants, mostly small fossil fuel based CHP plants but we also do electrical infrastructure including grid scale battery systems.

Most of my battery system installs have been for end users that have critical loads that need to do exactly what you are talking about, ride through a short outage until their backup generators are online and able to accept load. Usually hospitals but also a few manufacturing facilities that have very high costs for production shutdowns like biopharm.

Edit: Another datapoint is a 500 kWh unit with a 700kW discharge rate is closer to $300,000 so you are paying quite a bit for the extra output. There is a lot of copper involved for the larger transformer, larger switchgear bus, and additional inverters required to handle the extra current.

A problem for EV charging stations is getting a high capacity connection to the grid, and this sounds like a convenient solution for that. That battery could charge quite a few Teslas and you don't need very thick connection to the grid if it's running at full blast 24/7. Could also provide a bit of grid storage with any excess capacity.

I read somewhere that coal plants burning coal for a year releases more radioactive elements and heavy metal into the environment than if an equivalent-MW nuclear plant just dumped its radioactive water and core into the river when it was done with a fuel cycle (instead of properly disposing of it/containing it). I don't have the data in front of me to math it out, but that's what we should be comparing, not some moronic Chernobyl comparison. Chernobyl couldn't happen again no matter what kind of accident a nuclear reactor had.

It also helps if Dyatlov is not the reactor lead.

I mean, they had to make so many mistakes prior to the reactor amplifying their idiocy for them.

But you have those flipped! Going by the actual statistics on this matter, accidents related to coal power have killed hundreds or thousands of people in quick and horrific ways, whereas most nuclear power "disasters" entail a prediction of how cancer rates may rise X% over the next 30 years. Like it's not even comparable, coal is the bigger killer in the long and short terms.

You know how Germany's wind power expansion has basically come to a total stop last year? Now the Merkel government is trying to pass a ban on wind turbine construction in a radius of 1km around anything bigger than 4 residential houses. According to studies this would permanently stop any further wind power expansion on German soil and lead to a substantial reduction of capacity over time. Germany would start to reduce its renewable power generation and, presumably, switch to natural gas.

There are massive protests against that law right now and Merkel's junior coalition partner has announced that they will not support the law in parliament, but it's doubtful if they gonna break up the coalition over this cause elections would be disastrous for them.

through thousands of posts in D&D over a decade, I now believe I know what I'm talking about. if I post forcefully and confidently, I can convince others that is true. no one sees through my facade.
There might be nothing wrong with nuclear power, but how does it further the aims of individualist global anarchic communitarianism?

We can't solve climate justice without also resolving 1,500 years of colonial patriarchy, and we must stand in the path of anyone who would try.
