Market Dynamics

Drivers

•  Rising demand for data centers and electronics cooling drives the market growth.

The functional fluids market growth is driven by the increase in consumption of data centers and electronics cooling. The unprecedented increase in internet penetration, cloud computing, and digital services has resulted in a phenomenal growth in the number and size of data centers across the world. Such facilities create a considerable amount of heat, thus requiring advanced cooling technologies that rely extensively on high-performance heat transfer fluids. Functional fluids used in data center cooling systems help to maintain the operating temperature within safety limits, prevent equipment failure, and increase energy efficiency. Moreover, the increasing number of electronics in automotive, industrial automation, and consumer devices also drives the demand for reliable thermal management.

The Department of Energy (DOE) has the National Renewable Energy Laboratory (NREL) working on geothermal-based thermal energy storage systems that can be utilized to improve cooling efficiency in data centers, since up to 40% of the energy consumed by a data center is used to cool it.

The DOE estimates that energy use in U.S. data centers might triple over the next few years, and that they could eventually consume as much as twelve percent of total electricity.

Restrain

• Volatility in raw material prices may hamper the market growth.

The functional fluids market growth can be hindered, on the other hand, owing to the high dependency on petrochemical derivatives and base oils, concerning which raw material prices are volatile. The key inputs for these are derived from crude oil, the prices of which are very sensitive to geopolitical tensions, supply chain disruptions, regulation, global demand, etc. The profitability of manufacturers is greatly affected when crude oil prices jump, as it also causes a substantial increase in the cost of producing functional fluids (lubricants, hydraulic fluids, heat transfer fluids, etc.). Such volatility in pricing, however, is a challenge for companies to pass the additional costs to the end users, and therefore, these fluids are less than competitive in price-sensitive markets.

Opportunities                                                  

• Growing focus on defense modernization creates an opportunity in the market.

There is a major opportunity in the functional fluids market coming from the agenda of modernization of defense. Countries around the world are increasingly pouring a lot of money into strengthening their defense systems, building and buying the latest military vehicles, aircraft, naval fleets, and weapons systems. With modern high-performance materials such as high winds, fuel micro-meteors, and such, advanced defense platforms rely on highly specialized fluids (hydraulic fluids, thermal transfer fluids, lubricants, etc.) that operate reliably over wide temperature, pressure, and other such operational requirements. Functional fluids are essential to mission readiness, safety, and the long-term durability of high-performance equipment used by ground, sea, and air defense which drive the functional fluids market trends.

In its FY 2024 National Defense Industrial Strategy, the DoD directed USD 670 M+ in Defense Production Act grants and USD 1.6B in innovation funding to 160 projects, including hypersonics, shipbuilding, and critical materials. Investment incentives and grants for advanced manufacturing support domestic specialty fluid production and a secure supply chain of defense-grade fluid products.
