Driver- Electric Vehicle (EV) Market Expansion

The rapid expansion of the global EV market, valued at approximately US$400 Bn in 2024, is significantly driving demand for advanced coolants. Electric vehicles require specialized, non-conductive liquid cooling systems—accounting for about 60% of EV thermal management solutions—to ensure safe and efficient battery and motor operation. This need has prompted major players such as ExxonMobil to develop tailored coolant formulations for EVs.

According to the International Energy Agency’s Global EV Outlook 2024, EVs are expected to comprise around 40% of global vehicle sales by 2030. This surge, backed by government incentives and emissions regulations, particularly in North America and the Asia Pacific, is accelerating innovation in EV-compatible thermal management fluids.

Restraint - Environmental Concerns with Ethylene Glycol

Ethylene glycol (EG)-based coolants, while effective for thermal management, are increasingly restrained by environmental and health concerns. Globally, around two Mn tons of used coolant are generated annually, with improper disposal contributing to soil and water contamination. EG is highly toxic and poses serious risks to ecosystems if leaked or mishandled.

As a result, many regions are enforcing stricter environmental regulations and promoting sustainable practices in coolant usage. This has led to growing consumer resistance and industry-wide movement away from EG-based formulations. The trend is fueling demand for safer, eco-friendly alternatives such as propylene glycol (PG) and glycerine-based coolants, which offer lower toxicity and greater biodegradability.

Opportunity - Eco-Friendly Coolant Adoption

The transition to glycerine-based and propylene glycol (PG)-based coolants offers substantial growth opportunities, as bio-based coolants are projected to account for 15% of the global market by 2032.

These environmentally friendly formulations align with global sustainability targets and increasing consumer preference for green automotive solutions. Regions with stringent environmental regulations, such as the EU and North America, are driving this shift. Companies investing in biodegradable and low-toxicity coolants can gain a competitive edge by appealing to eco-conscious buyers and securing long-term partnerships with automakers aiming for net-zero emissions by 2050. This trend supports both regulatory compliance and innovation in sustainable thermal management.
