[Global] One of the world’s biggest oil companies is working on hundreds of low-carbon energy projects, from algae engineered to bloom into biofuels and cells that turn emissions into electricity.
The work by Exxon Mobil Corp. includes research on environmentally-friendly technologies in five to 10 key areas, according to Vice President of Research and Development Vijay Swarup. While any commercial breakthrough is at least a decade away, Exxon’s support for clean energy suggests the world’s most valuable publicly-traded oil company is looking toward the possibility of a future where fossil fuels are less dominant.
While Exxon has discussed some of its research before and runs advertisements about its work in algae, the remarks from Swarup are the first indication of the breadth of the oil company’s interests in alternative energies. It’s part of the $1 billion a year Exxon spends on research worldwide and the $8 billion it has spent since 2000 researching, developing and deploying low-carbon technologies.
“These areas are massively challenging, and if we can solve those, they will have huge impacts on our business,” said Swarup in a phone interview. “We bring more than money. We bring the science, the commitment to research.”
Exxon didn’t disclose the exact amount it’s spending on the green technologies. The broader investments it has made since the beginning of the century also include things like managing methane emissions from oil wells, on co-generation and on making its plants more efficient.
The company joins a growing list of oil majors hedging against the wider adoption of renewables, which could displace some 8 million barrels of crude demand a day, according to Bloomberg New Energy Finance. Some companies, like France’s Total SA, have made acquisitions to enter the business. Others, like Royal Dutch Shell Plc, are using experiences from running offshore rigs to develop wind farms in the North Sea.
Based in Irving, Texas, Exxon said its approach is different because its focusing on science, Swarup said. It has joined with about 80 universities and is collaborating with smaller companies on research.
Projects it’s working on include:
- Algae biofuels: Exxon is planning to harvest algae in ponds or oceans around the world and process it into a biofuel for regional distribution. Swarup expects that it will first be blended with diesel and jet fuel, but the goal is to eventually sell a 100 percent algae-derived fuel.
- Biodiesel made from agricultural waste. The company is working with Renewable Energy Group Inc. to use microbes to convert inedible crop residue like corn husks into biofuels. The two companies began their collaboration in 2016 and recently extended their joint research program.
- Carbonate fuel cells: Most fuel cells generate electricity by reacting chemically with natural gas or hydrogen. These ones use carbon dioxide. Exxon and FuelCell Energy Inc. are researching how the devices can be used in carbon capture and storage and to generate electricity at the same time. It’s building a pilot plant within a few months and is working on the engineering of the facility now.
- Process intensification: Exxon is working with Georgia Institute of Technology to develop a more efficient way of refining crude oil into plastic. It involves using a membrane and osmosis rather than heat. Exxon is targeting carbon dioxide emission reductions by as much as half with the process.
“We are still 10 plus years away” for both the algae biofuels and carbonate fuel cells to be deployed at scale, according to Swarup, who said the company’s been focusing research on algae for eight years.
Swarup’s biggest priority is finding and developing projects that can be scaled to Exxon’s global reach. The company operates on six continents and had revenues of $198 billion last year, bigger than the combined economies of Qatar and Kuwait, two members of the Organization of Petroleum Exporting Countries.
“The common denominator when we’re looking at from a research standpoint is that we understand our role as a corporation and that is scalable solutions,” Swarup said.
“Oil and gas companies tend to consider other elements of an investment beyond just the short-term revenue potential,” said Rick Wheatley, executive vice president of new growth at Xynteo Ltd., a consultancy that advises Shell, Statoil ASA and Eni SpA on sustainability and long-term planning. “They may be more likely to see technologies as pieces that can be combined into larger products or solutions and therefore have higher tolerance for early stage and experimental ideas.”
