Cut Carbon, Cut Costs: The Business Case for Energy-Efficient Lubricants

Across sectors, as companies step up efforts to improve energy efficiency, large-scale investments in renewable infrastructure often pose financial and operational challenges. However, smaller, cost-effective strategies, such as the adoption of high-performance lubricants, can deliver meaningful gains. At a recent online ISF Forum session, Kranthi Kiran C, Head of Digital Business – Asia Pacific Region at Freudenberg Chemical Specialities, built a compelling business case for the use of energy-efficient lubricants to drive both cost savings and carbon reduction. He also explored how optimised lubrication can enhance equipment performance, reduce energy consumption and contribute to a more sustainable, resilient ecosystem.

Lubricants: More Than Friction Reducers

In the global push for sustainability, businesses often focus on large-scale, high-investment solutions like renewables and hydrogen. However, this can obscure simpler, high-impact, low-disruption alternatives that deliver measurable benefits with minimal operational upheaval. One such overlooked lever is energy-efficient lubricants, an innovation that promises simultaneous reductions in energy consumption, carbon emissions and operational costs. Lubricants are typically associated with reducing friction and wear in machines. But as the field of tribology (the science of friction, wear and lubrication) has evolved, it has become evident that the chemistry behind lubricants can influence energy efficiency in profound ways. Advanced formulations such as Metallocene Polyalphaolefins (m-PAO) outperform traditional mineral oils and even older synthetic types like Polyglycol and standard PAO oils, offering greater chemical stability, thermal resilience and up to 30% lower friction coefficients. This translates directly into lower electricity usage and fewer unplanned downtimes.

Demonstrating the Business Case

One of the biggest barriers to adoption is the perception of high cost. Energy-efficient lubricants can indeed be more expensive upfront, but the payback period is typically under a year, owing to reduced energy bills and longer equipment life. For example, in a case study involving a cold rolling steel mill, switching lubricants led to energy savings worth over Rs 35 million annually. Importantly, these savings came without costly design modifications or production stoppages; and these results are not merely anecdotal. Accurate measurement and verification through energy audits are vital. Changes in power consumption must be measured under stable conditions, using consistent variables, often with third-party validation. Even a 2-6% drop in energy use is significant in high-load operations, with some facilities reporting even greater reductions.

Sectoral Applications and Tailored Impact

Energy-efficient lubricants are yielding results across diverse sectors. In heavy industries like steel, cement, chemicals and wind energy, their application in gearboxes and compressors has delivered proven energy and emission reductions. In food and beverage, the energy savings are lower but food-grade synthetics ensure compliance with stringent safety regulations while offering long-term cost advantages. Even sectors like real estate and property management can benefit. For instance, diesel generator sets typically require oil changes every six months, regardless of usage. By switching to high-performance lubricants, companies may reduce change intervals, pending OEM and regulatory approvals, saving on labour, material and disposal costs.

Lubricants as a Climate Tool

The true sustainability impact of lubricants goes beyond energy. Their entire life cycle, from material sourcing to disposal matters. Leading manufacturers now perform lifecycle assessments (LCA) and develop formulations that are biodegradable or meet ecological safety norms, particularly for marine, textile and precision industries. These innovations lower not only Scope 1 emissions, but also affect Scope 3 indirectly through reduced energy use and responsible end-of-life handling.
