IEP (at least in PLAN's design) should always have energy storage which is usually flywheel. Compared to flywheel, battery is lower in power density but higher in energy density. An IEP uses flywheel as buffer and backup to the grid because of flywheel's high power density. To provide equal power for reasonable long time, battery pack would be huge. I don't think the idea would work with today's battery tech, not in the forseeable future.

There's definitely space enough for CODLAD.
This is my point as well. It remains a mystery regarding whether it will be powered via CODAD or CODLAD. The latter will definitely be more step up without changing the propulsion completely (and thus, the 054 class designation).
The more likely installed power onboard the 054B FFG would be almost 30MW of power, comprised of 4x CS16V27 diesel engines of the 7MW-class. This is discounting the auxiliary propulsion systems.
TBH, that seems kinda low for an FFG of that size and displacement...
2x8 YJ-12s might be too much. 2x4 YJ-12s would be more suitable.

That isn't exactly what he's saying. He's comparing the propulsion in the Type 054B with that of the 054A.
The Type 054B has 4x CS16V27 diesel engines with 7.28 MW each. Which is basically 29 MW total. He rounds it up to 30 MW.
The Type 054B has like 50% more engine power and 50% more displacement than the Type 054A.

That’s already more power output than the French FDI frigate, which also uses CODAD and is similar in size and role.
Never mind! Take back my previous statement. Must have been looking at wrong data.
Well then, this just makes the propulsion for 054B even more mysterious. If the total output were less than 30MW via pure CODAD (not even CODLAD), then the speed of 054B would likely be under 25 knots, whilst there may not be enough power for the AESA radar and the mast. Doesn’t make sense

Would it be possible in the near future when the battery voltage can be increased significantly ? China has been very aggressive in that area technology
