Key Players
Competitive Landscape
Hyperscale and colocation buyers approve an immersion fluid only after server makers confirm warranty cover, fire engineers accept the flash point and pilot tanks run for months without faults. Shell chose a 12-month pilot in an operating Keppel facility to build a field history for GTL fluid.[1]
Oil majors compete on cost per litre and global supply, specialty chemical makers compete on two-phase performance and low global warming potential, and integrators such as Submer compete on complete tank systems and service. Castrol is using the OCP Marketplace to reach buyers who standardise on Open Compute designs.[5]

Buyers are asking for a fluid, a tank and a service plan from one contract, so fluid makers are pairing with server makers and integrators to bid as a group.
Who leads the immersion cooling market?
Shell is among the leaders, with an estimated 11% share of immersion cooling sales. Shell is also running a live fluid pilot with Keppel.[1] Chemours leads documented two-phase fluid work through the 2CRSi agreement.[2]
Which companies have documented positions?
Shell, Chemours, Fuchs and Castrol document fluid launches, pilots and certifications.[1][4][6][5] Submer documents partnerships and data center projects.[8]
What should buyers evaluate before approving a supplier?
Buyers check server maker approval, fire and electrical certification, flash point and fluid life in pilot tanks. Supply security, refill logistics and the end-of-life plan for used fluid also decide approval.
How is competition expected to change through 2036?
Fluid makers with OEM approval will gain share as hyperscale buyers narrow shortlists. Integrated offers of tank, fluid and service will gain more new-build halls from standalone fluid sales.
