Exploring the opportunities and challenges in a changing market
The growing demand for personal and commercial mobility in a world working to be more sustainable is driving the need for new hardware and lubricant technology options. Laura Pottorf, Global Base Stocks and Waxes Marketing Manager at ExxonMobil, talks to Insight about her views on these and other trends that are shaping the future global base stocks market and the challenges she expects to see ahead.
Base stocks play an important role in many diverse industries, which means the global market can be impacted by many different factors. Today, base stocks are increasingly used to develop advanced lubricant products that satisfy the hardware performance requirements of machinery and engines – ensuring they stay reliably in operation. But, it is becoming increasingly important that these products also deliver efficiency gains to support decarbonisation while also fitting in with customers’ sustainability aspirations.

The world continues to face the challenge of making sure people have the energy and products they need to live healthy, prosperous lives while also addressing climate change. These are two challenges of great importance, both necessitating an inclusive approach with the full cooperation and effort of companies, governments, and NGOs worldwide in order to address these critical issues.
Laura says she sees two macro trends that can be expected to play an important role in the industry going forward. “Firstly the global population is continuing to rise, and more people are entering the middle class, which will translate into an increase in the demand for personal mobility and other durable goods. Secondly, as the world moves towards a lower carbon future, numerous lower greenhouse gas (GHG) emission technologies with multiple options will be needed to reach the goals that society has.”

So both of these trends are going to shape the future for base stocks, including everything from total demand to the underlying demand trends to the higher qualities that will be needed to support efficiency improvements and new technologies. And so I really think the challenge for the industry during this period of change is to ensure that we've got base stocks and qualities available that can meet the needs of current and future engines and help keep them all operating at peak performance.
So while there's a lot of change and a lot of uncertainty, there also is opportunity for manufacturers that are working with their customers and strategically planning investments to reliably meet their customers' needs today and into the future.
According to ExxonMobil’s projections through to 2050, energy demand is expected to increase by 15% to support rising human development around the world and more people are likely to have access to personal mobility. Additionally, demand growth is expected in durable products, appliances, and consumable goods – although some of this will be offset by increased use of electrical vehicles and better efficiency in conventional engines. As Laura continues, “Combining these factors, our forecast indicates that overall demand for lubricants will continue to grow slightly for the next few decades, albeit at a slower pace than historically. Now, while overall growth is relatively small, at around 0.3% per year, there are going to be changes in the composition of that demand – particularly from both regional and quality perspectives.”

Looking forward from 2010 to 2035, the projected growth rate for Asia Pacific is more than double the global rate at approximately 0.8% per year. This region will be the growth engine for the world as more people move into the middle class. Interestingly, the growth will be fuelled by demand increases in India, Southeast Asia, and China. In contrast, Americas and the Europe, Africa, Middle East regions will be essentially flat versus 2010 with demand offset by efficiency gains and electrification in mature markets.
We see continued growth in Group II and Group III to meet the increasing demand for improved efficiency across all sectors. Group III will grow at a faster rate than Group II, driven by the need in engine oils for low viscosity, low volatility base stocks with good oxidation stability. But despite that faster growth rate, our view is that Group II will remain the main grade.
Given the demand for higher qualities we also project a decline in Group I. There will still be a need for Group I, especially in certain applications where Group I just has performance attributes that are better suited than Group II. But in areas of overlap, where you could have either grade, our view is that Group II will continue to grow. So overall, while top line demand is relatively flat, the underlying trends are changing quite a bit.
In addition to the influence of regional and quality trends on base stock production, we were also keen to understand what role Laura sees for lower carbon footprint base stocks in support of the industry’s sustainability ambitions.

We think that we'll continue to see growth of re-refined base stocks driven by emerging regulations, better enforcement of existing requirements and improvements in used oil collection and processing.
Right now, bio-based lubricants are still a small portion of the overall market and mainly used in applications in environmentally sensitive areas. Now, the size of the market and pace of bio-based oil adoption could be guided by a number of factors, and that includes everything from regulatory environment, feed availability, cost, and performance.
But as we look forward over the next few decades, it's a period of uncertainty as no single pathway has been identified that can both meet the needs for increased energy demand and society's ambition for lower emissions.
We're going to need multiple solutions, and the solutions that come forward are going to be a function of government policy, technology innovation, and consumer preferences.
So it's that combination of factors that are going to be what drives the types of solutions that are available in what time period and at what scale. So again, while there's a lot of uncertainty, there's also a lot of opportunity.
With sustainability and net zero ambitions clearly driving significant change to the transportation and associated industries, we asked Laura to share what action ExxonMobil has taken. “We have identified 14 sustainability focus areas, which describe sustainability in the context of our business. These areas are where we believe we have the most potential to both impact ExxonMobil and society. You can find out more about our approach in each of these areas in our advancing climate solutions report, which you can read here. We have also announced our ambition for net zero greenhouse gas emissions by 2050."

As part of our strategy, with advances in technology and the support of clear and consistent government policies, we aim to achieve net zero operated scope one and two greenhouse gas emissions by 2050. Now to that end, we've taken a comprehensive approach to create emission reduction roadmaps for our major operated assets. The roadmaps build on our 2030 emission reduction plans, which are within the Paris Agreement pathways, and notably include reaching net zero emissions in our unconventional Permian Basin operated assets by 2030.
Now in terms of lower emissions investments, through 2027 we plan to invest approximately $17 billion on initiatives to lower greenhouse gas emissions. These investments are designed to make possible reduced emissions in our operations and are also directed towards reducing others' emissions through commercialising and scaling technologies such as carbon capture and storage, hydrogen and biofuels.
Sustainability and decarbonisation are high on the agenda of organisations in the mobility, lubricants and base stocks industries, and Laura anticipates a period of significant change ahead, where staying close to the market and understanding customers' needs will be essential. “Given the evolution of the market, as a manufacturer, it is important to have an intelligently designed base stock slate that's fit for the lubricant qualities that will comprise the majority of industry demand and to support it with technical expertise that can help customers identify and implement solutions as the market changes. In addition, investment in modern manufacturing and plants that are integrated with large petro-chemical complexes, to ensure reliable supply over a range of market conditions, will be key to reliably meeting customer needs both today and into the future.”
