Spring-based ExxonMobil has teamed up with Japan’s Mitsubishi to potentially produce low-carbon ammonia and nearly carbon-free hydrogen at ExxonMobil’s facility in Baytown.

ExxonMobil and Mitsubishi are still working out details of the arrangement, such as equity participation in the project and use of the low-carbon ammonia.

“We look forward to furthering our leadership position, alongside Mitsubishi Corporation, to advance low-carbon hydrogen and ammonia globally, helping the world achieve a lower emission future,” Dan Ammann, president of ExxonMobil Low Carbon Solutions, says in a news release.

The ammonia would be shipped to Japan for power generation, process heating, and other industrial purposes. In conjunction with this project, Mitsubishi would convert part of a liquified petroleum gas (LPG) terminal into an ammonia terminal. The Japanese conglomerate plans to partner with Japanese petroleum company Idemitsu Kosan for ammonia purchases and a joint equity stake in the Baytown project.

The Baytown project is expected to generate as much as one billion cubic square feet of low-carbon hydrogen per day and more than one million tons of low-carbon ammonia per year.

A financial decision on the project is set for 2025, with the project coming online in 2029.

“We are excited to be closely collaborating with ExxonMobil to develop low-carbon hydrogen and ammonia supply chains that will bridge the United States and Japan,” says Masaru Saito, CEO of Mitsubishi’s Environmental Energy Group. “Together, we will lead this joint initiative to assist in the acceleration of the hard-to-abate sectors’ transition to clean energy.”

team work

Spring-based energy giant ExxonMobil has enlisted Air Liquide as a partner for what’s being billed as the world’s largest low-carbon hydrogen project.

The deal will enable transportation of ExxonMobil’s low-carbon hydrogen through Air Liquide’s pipeline network. Furthermore, Air Liquide will build and operate four units to supply 9,000 metric tons of oxygen and up to 6,500 metric tons of nitrogen each day for the ExxonMobil project.

Air Liquide’s U.S. headquarters is in Houston.

ExxonMobil’s hydrogen production facility is planned for the company’s 3,400-acre Baytown refining and petrochemical complex. The project is expected to produce 1 billion cubic feet of low-carbon hydrogen daily from natural gas and more than 1 million tons of low-carbon ammonia annually while capturing more than 98 percent of the associated carbon emissions.

“Momentum continues to build for the world’s largest low-carbon hydrogen project and the emerging hydrogen market,” Dan Ammann, president of ExxonMobil Low Carbon Solutions, says in a news release.

The hydrogen project is expected to come online in 2027 or 2028.

ExxonMobil says using hydrogen to fuel its olefins plant at Baytown could reduce sitewide carbon emissions by as much as 30 percent. Meanwhile, the carbon capture and storage (CSUS) component of the project would be capable of storing 10 million metric tons of carbon each year, the company says.

Texas thrives as No. 1 best state for homesteading and gardening

lone star state

If social media is any indicator, homesteading has been one of the hottest trends of 2024. And Texas is leading the charge as the No. 1 best state for homesteading and gardening, according to a new report by First Saturday Lime.

Analysts at First Saturday Lime, an insect repellant company featured on Shark Tank, evaluated the "suitability for sustainable living" across all 50 states based on six factors: Climate, community interest (a.k.a online search trends), gardening resources, farmland costs, and others.

The Lone Star State led the nation with the most farms and ranches on the market and the highest total acreage for sale. As of the study's publication, there were 7,520 total properties for sale, spanning more than 2.19 million acres of land.

Texas also ranked favorably for its farmland affordability. The state came in at No. 9 nationally with its average farmland price coming out to $2,800 per acre, the report said.

For comparison, New Mexico (which ranked No. 11 overall) had the most affordable average price per acre of farmland at just $700 per acre. Massachusetts (No. 48) and Connecticut (No. 42), however, tied for the most expensive price per acre, at $14,300.

Among the three remaining categories in the study, Texas performed the worst for its "gardens on Yelp per capita" rank. The study calculated Texas has 0.30 gardening and community garden establishments on Yelp per capita, placing Texas at No. 49.

Meanwhile, Texas' historically hot weather meant it ranked No. 43 out of all 50 states in the "favorable climate" rank, and the state earned a middle-of-the-road No. 35 rank in the "search interest per capita" category.

"Homesteading and gardening are growing in popularity, but some states provide better opportunities than others," the report's author wrote. "Whether you're after fresh produce or the freedom of self-sufficiency, choosing the right state can make all the difference."

Following behind Texas to complete the top three best states for homesteading and gardening are Oregon (No. 2) and Washington (No. 3), two notoriously rainy West Coast states.

Meanwhile, three East Coast states ranked at the bottom of the list as the worst states for homesteading and gardening: Rhode Island (No. 50), New Jersey (No. 49), and Massachusetts (No. 48).

The top 10 best states for homesteading and gardening are:

  • No. 1 – Texas
  • No. 2 – Oregon
  • No. 3 – Washington
  • No. 4 – Vermont
  • No. 5 – Delaware
  • No. 6 – Arizona
  • No. 7 – Wyoming
  • No. 8 – Montana
  • No. 9 – Hawaii
  • No. 10 – Colorado

The study sourced its data from Yelp, Google Trends, and the UDSA to determine each state's ranking.

Houston researchers develop catalyst for emission-free hydrogen production using light instead of heat

switch flipped

Researchers at Rice University have developed a catalyst that could render steam methane reforming, or SMR, entirely emission-free by using light rather than heat to drive the reaction.

The researchers believe the work could prove to be a breakthrough for extending catalyst lifetimes. This will improve efficiencies and reduce costs for a number of industrial processes that are affected by a form of carbon buildup that can deactivate catalysts called coking.

The new copper-rhodium photocatalyst uses an antenna-reactor design. When it is exposed to a specific wavelength of light it breaks down methane and water vapor without external heating into hydrogen and carbon monoxide. The importance of this is it is a chemical industry feedstock that is not a greenhouse gas. Rice’s work also shows that the antenna-reactor technology can overcome catalyst deactivation due to oxidation and coking by employing hot carriers to remove oxygen species and carbon deposits, which effectively regenerates the catalyst with light.

The new SMR reaction pathway build off a 2011 discovery from Peter Nordlander, Rice’s Wiess Chair and Professor of Physics and Astronomy and professor of electrical and computer engineering and materials science and nanoengineering, and Naomi Halas. They are the authors on the study about the research that was published in Nature Catalysis. The study showed that the collective oscillations of electrons that occur when metal nanoparticles are exposed to light can emit “hot carriers” or high-energy electrons and holes that can be used to drive chemical reactions.

“This is one of our most impactful findings so far, because it offers an improved alternative to what is arguably the most important chemical reaction for modern society,” Norlander says in a news release.

The research was supported by Robert A. Welch Foundation (C-1220, C-1222) and the Air Force Office of Scientific Research (FA9550-15-1-0022) with the Shared Equipment Authority at Rice providing data analysis support.

“This research showcases the potential for innovative photochemistry to reshape critical industrial processes, moving us closer to an environmentally sustainable energy future,” Halas adds.

Hydrogen has been studied as it could assist with the transition to a sustainable energy ecosystem, but the chemical process responsible for more than half of the current global hydrogen production is a substantial source of greenhouse gas emissions.Hydrogen is produced in large facilities that require the gas to be transported to its point of use. Light-driven SMR allows for on-demand hydrogen generation,which researchers believe is a key benefit for use in mobility-related applications like hydrogen fueling stations or and possibly vehicles.
