Climate solutions Energy and innovation Sustainability Operations News Investors About Global ENERGY TECHNOLOGIES Energy efficiency ExxonMobil constantly strives to improve performance and streamline our processes in order to improve energy efficiency and reduce environmental impact. EXECUTING AT SCALE Deploying proven technology to reduce emissions Technologies allow us to reduce, reuse and recycle energy throughout our operations. Running large upstream, refining and chemical operations to provide the products consumers rely upon generates tremendous amounts of excess heat. To ExxonMobil engineers, that lost heat offers opportunity. With cogeneration we capture the waste heat and utilize it for our manufacturing processes, resulting in a reduced need for boilers, not to mention the fuel saving that goes with those boilers. Due to its inherent energy efficiency, the use of cogeneration leads to reduced greenhouse gas emissions. Our cogeneration facilities enable the avoidance of approximately 6 million metric tons per year of greenhouse gas emissions. up to 75% less carbon dioxide is produced from gas-fired cogeneration compared to coal-based power ~ 5,400 megawatts of gross cogeneration capacity in more than 100 installations, which is equivalent to the annual electricity needs of 4.3 million U.S. homes EXXONMOBIL'S ROLE A leader in cogeneration Over the past decade, we have added about 1,000 megawatts of cogeneration capacity and continue to develop additional investment opportunities. Avoiding 6 million metric tons per year of greenhouse gas emissions through cogeneration Article • Oct. 9, 2018 ENERGY FACTOR Producing power efficiently for our own operations There’s nothing flashy about cogeneration, and in a hashtag environment, the term is rarely trending. But what cogeneration lacks in headline-grabbing cache, this emission-reducing technology makes up for by producing concrete results.

Within the partnership’s purview is a project on how to optimize the energy grid to meet future energy demands while lowering emissions with the most cost-effective approach. Research partners Energy Factor • July 22, 2021 Bold technologies for today and tomorrow The dual challenge of meeting the world’s energy needs while lowering greenhouse gas emissions will continue long after economies restart, businesses reopen and travel resumes. Carbon capture Energy Factor • Aug. 4, 2020 Working together on tomorrow's energy ExxonMobil and researchers from Georgia Tech and Imperial College London are working together on membrane technology research that could reduce carbon dioxide emissions and lower the energy required during the process of refining crude oil.
