LG Electronics and SK Enmove signed an MOU to jointly develop next-generation refrigerants with a GWP below 150 and free of PFAS. They will also work on matching refrigeration oils and immersion cooling for AI data centers. The partnership targets tighter refrigerant regulations in Europe and North America, and aims to expand cooling tech to ESS and EV components. The two firms will combine SK Enmove's refrigerant expertise with LG's HVAC system experience. They have already run joint immersion cooling demos with US firm GRC. This could reduce the climate impact of cooling systems, which are a major source of emissions. The move also addresses rising energy demand from AI data centers. For readers tracking low-carbon industry, this is a concrete step toward lower-GWP refrigerants and more efficient data center cooling. Watch for commercialization timelines and whether the refrigerant actually hits the market before regulation deadlines.

Good to see refrigerant makers moving on PFAS-free low GWP options. The <150 GWP target aligns with EU F-gas rules. But the real test is whether the oil compatibility holds up in field conditions. Keep an eye on that.

Lower GWP refrigerants matter, but the energy efficiency of the whole system matters more. Immersion cooling for data centers could cut cooling energy a lot. Hoping they publish performance data from the GRC demos.

AI data center cooling is a fast growing load. If immersion cooling gets adopted at scale, it could flatten the demand curve. But deployment depends on retrofitting existing centers, not just new builds. That's the bottleneck.

The refrigerant regulation push is real, but PFAS bans are moving differently across jurisdictions. This partnership looks like a hedge against both. Still, without clear phase-out timelines, manufacturers might delay switching. Regulation needs to be predictable.

For building HVAC, low GWP refrigerants are great, but retrofits are costly. The real win is if these oils and refrigerants drop into existing systems with minor changes. Otherwise payback will be too long for most commercial buildings.
