Korail Proposes Two-Track Strategy for Rail Carbon Neutrality
During a seminar, Korail's Carbon Neutrality Promotion Team presented a "two-track strategy" to achieve rail carbon neutrality, focusing on energy consumption reduction and renewable energy expansion, including a proposed market mechanism for regenerative energy.
Our take
Will Korea's national rail operator become a large buyer of renewable power?
Korea's national rail operator could become a large renewable power buyer, but it has set out a target and on-site solar plans, not a plan for buying the remaining renewable share.
Its annual electricity bill of about 630 billion won makes it a sizeable potential offtaker, and own solar is planned to cover only part of its use. The deciding signal is whether it issues power purchase or site tenders.
What the source says
- Jeon Yong-joo Jeon Yong-joo stated that rail carbon neutrality can be realized when energy saving technology, renewable energy expansion, and a regenerative energy trading and settlement system are built together.
- Korail proposes reorganizing data and market systems to allow regenerative energy to be recognized as actual electricity and be traded and settled.
- The expansion of railway electrification presents a "paradox of carbon neutrality" where increased electricity consumption can lead to higher carbon emissions from power generation.
- Korail is pursuing technology to store and reuse regenerative energy generated during train braking in batteries.
- Korail is conducting R&D to transport electricity to where it is needed using battery trains to address imbalances between renewable energy production and consumption areas.
- Korail plans to gradually cover 10-20% of its electricity consumption by installing solar facilities on railway infrastructure like roofs, fences, sound barriers, and track surroundings.
- Korail is pursuing a solar power generation project of approximately 20MW at Goyang Rolling Stock Depot.
- Jeon Yong-joo Jeon Yong-joo explained that as domestic carbon prices rise, a structure is forming where facility improvements are more advantageous than purchasing emission allowances under the Carbon Emissions Trading System.
For investors — Solar developers and corporate PPA sellers should watch for procurement tenders from the operator, with rail land such as depots and sound barriers already used as the on-site route.
Merchant storage investors and optimisers should assign no revenue to braking-energy trading, since it has no settlement rule and the operator is pursuing storage of that energy in-house.
Watch: Announcement or progress on market and data system reforms for regenerative energy trading and settlement.
