Hyundai's Ulsan EV rebuild makes up half of Seoul's 7.9 trillion won fast-track package

The investment figures the government attached to named projects add up to 7,871.7 billion won. That is 4 trillion for Hyundai's Ulsan rebuild, 3 trillion for clean hydrogen, 761.5 billion for the Muan national industrial complex, 70.2 billion expected from extending a battery hazardous-materials exemption to materials, parts and equipment makers, and 40 billion for the sonar maker Ible Photonics ^{[5][8][10][11][12][3]}. Rounded, the sum is the 7.9 trillion won headline ^[4][3]. The chip-fab measures do not have to be counted to reach it ^[3].

On the government's reading, approvals are the bottleneck. The 28 months saved at Ulsan, a 70% cut, fall on the largest project in the list ^[1][2]. A second reading is that this is a fast-track for stalled projects, or rather for about 4.9 trillion won of them, because the 3 trillion won of hydrogen investment, 38% of the total, depends on an auction ^[4][5][8]. On a third reading, the measure SK hynix pushed for is the slowest in the package, with the contracting rule change to be pursued next year ^[2][14].

I think the second reading is the accurate one. The hydrogen auction covers 500 gigawatt-hours a year on 15-year fixed-price contracts, about 7,500 gigawatt-hours over the term, and its scoring will give extra weight to contributions to the domestic clean hydrogen ecosystem ^[8][6]. The announcement does not give the contract price. For that 3 trillion won of investment, a price fixed for 15 years matters more than any permit clock ^[8]. The counter-case is Ulsan, where the delay was a list of approvals: environmental, traffic and disaster impact assessments, plus environmental, safety and construction permits, had been expected to take more than three years ^[6]. At 4 trillion won, that one plant outweighs the hydrogen money ^[5][8].

The fab changes deal with friction inside working plants. Current rules require electrical and telecom work to be contracted separately, and general contractors find such projects hard to oversee, according to the announcement ^[13]. SK hynix is said to have argued that the split raises the risk of serious accidents, delays construction through scheduling coordination and slows maintenance through liability disputes between contractors ^[15]. Cylinder cabinets, which protect the containers supplying production gases, currently need a technical review and a permit amendment each time a few more are installed ^[16].

The one measure that puts a won figure on time saved sits outside the investment total. Cutting the environmental-assessment consultation for blending LNG into byproduct-fueled combined-cycle plants to within one month, from more than three, is expected to save about 69.7 billion won in fuel ^[9][3].
