Energy and innovation
Article July 15, 2019
R&D has been part of ExxonMobil’s DNA since our company began more than 135 years ago. Our innovations have helped provide the energy fundamental to modern life – from the clean, efficient fuels that power today’s transportation to the natural gas that provides light and heat to homes and businesses.
Today, our world faces a dual challenge: meeting growing demand for energy while also reducing environmental impacts, including the risks of climate change. ExxonMobil is committed to doing our part.

Today, we are working to develop the next generation of energy solutions, including: advanced biofuels; carbon capture and storage; natural gas technologies; and new energy efficiency processes. In addition to our robust in-house capabilities, we collaborate with leading research and technology companies, national labs and universities, and others involved in breakthrough energy research. While all forms of energy are needed – including natural gas and renewables such as wind and solar – new technologies will be required to meet the world’s emissions-reduction goals.
ExxonMobil is looking for affordable, scalable solutions that address the three main areas of energy use: transportation, power generation and manufacturing. We are also deploying advanced technologies in these areas where applicable.
Scientists at ExxonMobil are working to transform algae and plant waste into biofuels that could one day be used for transportation. These advanced biofuels offer the possibility of achieving significant greenhouse gas reductions compared to today’s transportation fuels. They could also minimize impacts on land, fresh water and food supplies compared with traditional biofuels like corn or sugar cane. Algae naturally produce oils that can be turned into a renewable, lower-emission fuel. ExxonMobil and Viridos (formerly Synthetic Genomics, Inc.) are working together to identify and enhance algae strains capable of high lipid production while maintaining desirable growth rates.
ExxonMobil is studying the production of biodiesel by fermenting cellulosic sugars in agricultural residues from places like farms and lumber mills.
In 2018, Viridos and ExxonMobil began field testing algae strains at the California Advanced Algal Facility. Our goal: to have the technical capability to produce 10,000 barrels a day of algae biofuels by 2025.
Biofuels used today are largely derived from agricultural crops. Sugar cane and corn are used to make ethanol, while biodiesel is made from vegetable oils like soy. Biofuels made from algae and cellulosic biomass (abundant plant waste such as corn stalks and wheat straw), however, could provide a renewable fuel source that does not compete with supplies of food or fresh water. These advanced biofuels have the potential to be produced on a large scale, and are derived from sources that consume CO2.
From production to combustion, here are seven reasons why we think the answer could be yes. Find out why these renewable energy sources are so promising.
They consume CO2
Like all plants, the sources of cellulosic biomass consume CO2 from the atmosphere as they grow. Algae also consume CO2 to grow, using the same process of photosynthesis.
On a life cycle basis, algae and cellulosic biofuels emit about half as many greenhouse gases as petroleum-derived fuel.
Based on current technology, an acre of algae could yield more than 2,000 gallons (7,570 liters) of fuel. Compare that to 650 gallons per acre for palm oil and 50 for soybean oil. We’re working to make algae even more productive in the future.
Algae can be harvested repeatedly throughout the year unlike other feedstocks, such as corn, which are harvested only once a year.
Turning waste to fuel
Cellulosic biomass uses waste plant materials, such as crop residue like corn stalks, sawdust and other wood waste.
Algae can be cultivated on land unsuitable for other purposes, with water that can’t be used for food production. Cellulosic biomass can be derived from agricultural waste or woody biomass, which also do not compete with food.
Fuel derived from algae and cellulosic material can be pumped into existing diesel automobiles without making major changes to car engines and infrastructure.
The abundance and versatility of natural gas make it a valuable energy source to meet a wide variety of needs, and help the world shift to less-carbon-intensive energy sources. Natural gas is an ideal fuel for reliable power generation, and supplements intermittent renewable sources such as solar or wind. In the United States, the power sector’s shift from coal to natural gas has played a key role in bringing U.S. energy-related CO2 emissions to 1990s levels despite significant growth in energy demand. Recent advances in production technologies have unlocked vast new supplies of natural gas in North America that previously were uneconomic to produce. ExxonMobil is one of the largest natural gas producers in the United States.
ExxonMobil is committed to reducing emissions of methane from our operations and encouraging others across the natural gas value chain to do the same.
ExxonMobil is a leader in liquefied natural gas (LNG) technology that will drive lower-emission energy solutions and help supply cleaner-burning natural gas to markets around the world.
CO2 can be captured, compressed and injected underground for permanent storage. The Intergovernmental Panel on Climate Change has recognized carbon capture as essential to meeting global emissions-reduction goals. ExxonMobil, along with its academic and private-sector partners, is focused on new ways to capture CO2 from industrial and power generation sources, as well as directly from the atmosphere. Our research portfolio spans a wide range of technologies, including novel materials and processes.
ExxonMobil is a sponsor of the National Carbon Capture Center, a U.S. Department of Energy research facility, and is a founding member of the Global CCS Institute.
In 2019, ExxonMobil and Global Thermostat signed a joint development agreement to advance breakthrough technology that can capture and concentrate carbon dioxide emissions from industrial sources, including power plants, and the atmosphere.
ExxonMobil is exploring an exciting new possibility: using carbonate fuel cells to more economically capture CO2 emissions from gas-fired power plants. This novel approach would significantly reduce the energy needed to capture CO2, is easier to operate than existing technologies, and can be deployed in a modular fashion in multiple industry settings.
Carbonate fuel cell technology could make carbon capture more affordable for industrial sites and power plants.
Manufacturing and power generation account for about 70% of global energy-related greenhouse gas emissions.
ExxonMobil is looking to solve a big challenge: how to reduce emissions from manufacturing processes. One focus area is process intensification – the development of breakthrough technologies that could make manufacturing far more efficient. Our goal is to develop novel process technologies, including membranes and other advanced separations, catalysts and high-efficiency reactors, that can lower CO2 emissions by 25% or greater.
ExxonMobil is a member of the Rapid Advancement in Process Intensification Deployment (RAPID) Institute, a public-private partnership sponsored by the U.S. Department of Energy focused on significantly reducing the energy intensity of petroleum and chemical industry operations.
Since 2000, ExxonMobil has spent more than $2 billion to make our downstream facilities more energy efficient, resulting in a 10% improvement in energy intensity.
The industrial sector, which produces everything from steel to cellphones, accounts for about one-third of global energy-related CO2 emissions. ExxonMobil is researching a range of process- intensification technologies that could significantly reduce emissions associated with manufacturing.
ExxonMobil and Georgia Tech have developed a potentially revolutionary technology that could significantly reduce greenhouse gas emissions associated with plastics manufacturing by using a molecular filter – rather than energy and heat – to perform a key step in the process. It could be 50 times more efficient than today’s separation techniques.
High-efficiency reactors: ExxonMobil is working to reduce the energy needed to transform hydrocarbons into other useful products. We focus on thermal efficiency, modern reactor design and process miniaturization.
ExxonMobil develops and produces a range of petroleum-based products that help our customers reduce their greenhouse gas emissions and improve efficiency. These include resilient, lightweight automotive plastics that reduce overall vehicle weight, as well as advanced tire materials and transportation fuels and lubricants – all of which can enable cars and trucks to go even farther between fill-ups.
Our advanced products include packaging solutions that save fuel and avoid food waste, and building materials that make homes and offices more energy efficient.
Our high-performance lubricants – used in more than 40,000 wind turbines worldwide – improve sustainability because they need replacing less frequently, reducing the volume of used oil that needs to be disposed of or recycled.
A product’s potential environmental impact extends beyond its manufacturing and use. It also includes the acquisition of raw materials used to make the product, as well as its transport and disposal. In other words, a product’s estimated environmental impact should reflect its entire life cycle. ExxonMobil uses in-house experts and tools to conduct environmental life cycle assessments of emerging products and activities. In doing so, we are able to assess which technologies have the potential to deliver the game-changing results required to transition to a lower-carbon energy system.
ExxonMobil also collaborates with researchers at universities to advance the science of life cycle assessments. We have developed new approaches to quantifying environmental impacts associated with energy systems and published our findings in peer-reviewed journals.
ExxonMobil develops technologies that reduce carbon emissions over a product’s life cycle. For example, we make a range of advanced products – such as materials for lightweight plastic packaging – that help manufacturers reduce transportation energy use, emissions and waste.
In our search for energy and environmental solutions, ExxonMobil partners with companies whose expertise in certain areas complements our own. We also work directly with the users of our energy and chemical products – including automakers and packaging companies – to develop new products that reduce energy use and emissions.
ExxonMobil and IBM are jointly researching the use of quantum computing to develop next-generation energy and manufacturing technologies.
ExxonMobil scientists work directly with a range of automakers to develop fluids and lubricants specifically made to meet the unique needs of electric vehicles.
No single company or entity is capable of developing the breakthroughs needed to meet the world’s energy and environmental challenges. That’s why ExxonMobil casts a wide net in the search for new energy technologies – collaborating with universities, national labs, and other companies and innovators around the world.
ExxonMobil’s R&D program spans a wide range of focus areas, including catalysts and other advanced materials, computational modeling, and process engineering. ExxonMobil also has been a leader in climate research for more than four decades. Our findings are consistently published in peer-reviewed publications.
ExxonMobil works with about 80 universities around the world to explore next-generation energy and environmental solutions.
The centerpiece is our investment in five global energy centers: the MIT Energy Initiative; Princeton E-ffiliates Partnership; Stanford Strategic Energy Alliance; The University of Texas Institute; and the Singapore Energy Center led by the Nanyang Technological University and National University of Singapore. ExxonMobil has committed $175 million to fund breakthrough energy research at these centers.
In 2019, ExxonMobil formed a partnership with the U.S. Department of Energy’s National Renewable Energy Laboratory and National Energy Technology Laboratory, to jointly research and develop lower-carbon energy systems and technologies.
This unique collaboration will focus on next-generation biofuels, carbon capture, life cycle assessment and other promising areas.
Meeting the dual challenge is a global issue that requires the collaboration of governments, industries, consumers and other stakeholders. ExxonMobil has been vocal in our support of an economy-wide price on CO2 emissions.
In 2018, we joined the Oil and Gas Climate Initiative, a voluntary initiative representing more than a dozen of the world’s largest oil and gas producers working collaboratively toward solutions to mitigate the risks of climate change. We continue to support the Paris Agreement as an important framework for addressing climate-change risks.
