Summary
Experts debate energy solutions for Korea's semiconductor mega clusters, stressing an all‑of‑the‑above strategy with renewables, gas, and nuclear to meet massive new power demand while balancing cost, speed, and carbon goals.
- 39.7 GW of new power demand from Yongin and Honam clusters, equivalent to 40 nuclear reactors.
- Short‑term: only gas power can be built fast enough, with CHP and fuel cells as leading options.
- Renewable energy must scale from 37 GW to 250 GW by 2040 for economic and climate reasons.
- Nuclear is essential for long‑term baseload but faces waste disposal and public acceptance hurdles; SBTi now accepts nuclear as carbon‑free.
- Transmission grid expansion is critical and slow, with standard 9‑year projects often taking 21 years.
- RE100 commitments pressure Samsung and SK Hynix to secure renewable energy certificates, but China and TSMC use cheap RECs, not real green electrons.
- KEPCO's 200 trillion won debt hampers investment; recapitalization and community incentives are needed.
- Pragmatic, non‑ideological deployment of all available energy sources is the only viable path forward.
