ExxonMobil has updated its corporate plan through 2027, which will reflect their continued strategy to provide the products that work towards lowering emissions.

ExxonMobil is pursuing more than $20 billion of lower-emissions opportunities through 2027. The $20 billion request represents the third increase in the last three years, and is in addition to the company’s recent $5 billion all-stock acquisition of Denbury. Denbury helped expand carbon capture and storage opportunities through access to the largest CO2 pipeline network in the United States.

The portfolio will include opportunities in lithium, hydrogen, biofuels, and carbon capture and storage. The company is expecting that in aggregate it is expected to generate returns of approximately 15 percent and could potentially reduce third-party emissions by more than 50 million tons per annum (MTA) by 2030, which aligns with the company’s goals to combat climate change.

The company’s Low Carbon Solutions business reduces consumer’s greenhouse gas emissions, and will get approximately 50 percent of the planned investments support to help build this core part of ExxonMobil’s goal. The balance of the company’s low carbon capital will be used to reduce its own emissions, which will support its 2030 emission reduction plans and its 2050 Scope 1 and 2 net-zero ambition.

In addition, they are developing a leading position in lithium by fully leveraging its upstream skills in geoscience, reservoir management, efficient drilling, fluid processing, and extraction to separate lithium from brine. The company’s first phase of lithium production in southwest Arkansas is currently underway with first production is expected in 2027, and possible global expansion of the project. ExxonMobil aims to produce enough lithium to supply the manufacturing needs of approximately 1 million EVs per year by 2030.

“We continue to see more opportunities to harness our technology, scale, and capabilities to implement real solutions to lower emissions and to profitably grow our Low Carbon Solutions business,” Darren Woods, chairman and CEO, says in a news release. “Success in accelerating emission reductions requires the development of nascent markets. We need technology-neutral durable policy support, transparent carbon pricing and accounting, and ultimately, customer commitments to support increased investment. We’re actively advocating for each of these areas so we can grow a profitable, and ultimately large, low carbon business.”

In the Permian Basin, ExxonMobil is on track to reach net-zero emissions for unconventional operations by 2030. They expect to leverage its Permian greenhouse gas reductions plans to accelerate Pioneer’s net-zero ambition by 15 years (2035 from 2050.)

Recently, ExxonMobil and Pioneer Natural Resources announced an agreement for ExxonMobil to acquire Pioneer, which is an all-stock transaction valued at $59.5 billion, or $253 per share, according to ExxonMobil’s closing price on October 5, 2023. The merger combines Pioneer’s more than 850,000 net acres in the Midland Basin with ExxonMobil’s 570,000 net acres in the Delaware and Midland Basins, of which the companies will have an estimated 16 billion barrels of oil equivalent resource in the Permian.

The plan also intends to deliver $6 billion in additional structural cost reductions by the end of 2027, which should bring the total structural cost savings to $15 billion compared to 2019. Upstream earnings potential is expected to more than double by 2027 versus 2019, which is attributed to investments in high-return, low-cost-of-supply projects.

Other plan highlights included:

  • Expecting capital investments to generate average returns of around 30 percent, with payback periods less than 10 years for greater than 90 percent of the capex.
  • Generated $9 billion in structural cost savings with $6 billion more expected by 2027.
  • Increased pace of share repurchases to $20 billion per year from the Pioneer close through 2025.
  • Oil and gas production in 2024 to be about 3.8 million oil-equivalent barrels per day, rising to about 4.2 million oil-equivalent barrels per day by 2027.
  • Product Solutions is “leveraging scale and technology advantages” to nearly triple earnings potential by 2027 versus 2019.

In a new study published in the journal Science, a team of Rice University researchers shared findings on how acid bubbles can improve the stability of electrochemical devices that convert carbon dioxide into useful fuels and chemicals.

The team led by Rice associate professor Hoatian Wang addressed an issue in the performance and stability of CO2 reduction systems. The gas flow channels in the systems often clog due to salt buildup, reducing efficiency and causing the devices to fail prematurely after about 80 hours of operation.

“Salt precipitation blocks CO2 transport and floods the gas diffusion electrode, which leads to performance failure,” Wang said in a news release. “This typically happens within a few hundred hours, which is far from commercial viability.”

By using an acid-humidified CO2 technique, the team was able to extend the operational life of a CO2 reduction system more than 50-fold, demonstrating more than 4,500 hours of stable operation in a scaled-up reactor.

The Rice team made a simple swap with a significant impact. Instead of using water to humidify the CO2 gas input into the reactor, the team bubbled the gas through an acid solution such as hydrochloric, formic or acetic acid. This process made more soluble salt formations that did not crystallize or block the channels.

The process has major implications for an emerging green technology known as electrochemical CO2 reduction, or CO2RR, that transforms climate-warming CO2 into products like carbon monoxide, ethylene, or alcohols. The products can be further refined into fuels or feedstocks.

“Using the traditional method of water-humidified CO2 could lead to salt formation in the cathode gas flow channels,” Shaoyun Hao, postdoctoral research associate in chemical and biomolecular engineering at Rice and co-first author, explained in the news release. “We hypothesized — and confirmed — that acid vapor could dissolve the salt and convert the low solubility KHCO3 into salt with higher solubility, thus shifting the solubility balance just enough to avoid clogging without affecting catalyst performance.”

The Rice team believes the work can lead to more scalable CO2 electrolyzers, which is vital if the technology is to be deployed at industrial scales as part of carbon capture and utilization strategies. Since the approach itself is relatively simple, it could lead to a more cost-effective and efficient solution. It also worked well with multiple catalyst types, including zinc oxide, copper oxide and bismuth oxide, which are allo used to target different CO2RR products.

“Our method addresses a long-standing obstacle with a low-cost, easily implementable solution,” Ahmad Elgazzar, co-first author and graduate student in chemical and biomolecular engineering at Rice, added in the release. “It’s a step toward making carbon utilization technologies more commercially viable and more sustainable.”

A team led by Wang and in collaboration with researchers from the University of Houston also shared findings on salt precipitation buildup and CO2RR in a recent edition of the journal Nature Energy. Read more here.
