The Houston-based clean energy subsidiary of Chevron is making a big splash in the clean hydrogen sector. It just acquired a majority stake in what’s being promoted as the world’s largest facility for clean hydrogen storage.

Chevron New Energies bought Salt Lake City-based Magnum Development from Houston-based private equity firm Haddington Ventures. As a result, the New Energies unit now owns a majority share of the Advanced Clean Energy Storage (ACES) project in Delta, Utah. A joint venture of Magnum Development and Mitsubishi Power Americas is developing ACES. Financial terms weren’t disclosed.

“Having been the primary financial sponsor behind this key energy hub since 2008, we believe this transaction will accelerate lower-carbon-intensity solutions that reduce emissions in the western United States,” says John Strom, managing director of Haddington Ventures.

ACES plans to use electrolysis to convert renewable energy into hydrogen and store the energy in salt caverns. The first phase, designed to convert and store up to 100 metric tons of hydrogen per day, is under construction and expected to begin commercial-scale operations in mid-2025.

“Using salt caverns for seasonal energy storage is a significant opportunity to empower hydrogen as an energy carrier and greatly expand energy storage resources throughout the U.S.,” says ACES contractor WSP, an engineering, environmental and professional services consulting firm.

The hydrogen facility will support Intermountain Power Plant, a Utah power plant operated by the municipal utility in Los Angeles. The stored hydrogen is expected to fuel a hybrid 840-megawatt combined-cycle gas turbine (CCGT) power plant that’ll replace an 1,800-megawatt, coal-fired power plant.

A CCGT plant harnesses exhaust heat from natural gas turbines to generate steam through a heat recovery steam generator, according to IPIECA, an oil and gas association that focuses on environmental and social issues. The steam is then fed to a steam turbine to supply additional power.

Michael Ducker, senior vice president of hydrogen infrastructure at Mitsubishi Power, says the ACES project “will serve as a blueprint for future hydrogen opportunities.”

“We seek to leverage the unique strengths of each partner to develop a large-scale, hydrogen platform that provides affordable, reliable, ever-cleaner energy and helps our customers achieve their lower carbon goals,” says Austin Knight, vice president of hydrogen at Chevron New Energies.

Chevron New Energies is marketing its low-carbon hydrogen offering to sectors like transportation, power, and industrial. These sectors face especially big hurdles in their efforts to reduce greenhouse gas emissions.

In June 2022, the U.S. Department of Energy (DOE) issued a $504.4 million loan guarantee to finance ACES. The facility will combine 220 megawatts of alkaline electrolysis with two 4.5 million-barrel salt caverns for storage of clean hydrogen.

ACES expects to create up to 400 construction jobs and 25 permanent jobs.

A team of researchers at the University of Houston has made two breakthroughs in addressing climate change and potentially reducing the cost of capturing harmful emissions from power plants.

Led by Professor Mim Rahimi at UH’s Cullen College of Engineering, the team released two significant publications that made significant strides relating to carbon capture processes. The first, published in Nature Communications, introduced a membraneless electrochemical process that cuts energy requirements and costs for amine-based carbon dioxide capture during the acid gas sweetening process. Another, featured on the cover of ES&T Engineering, demonstrated a vanadium redox flow system capable of both capturing carbon and storing renewable energy.

“These publications reflect our group’s commitment to fundamental electrochemical innovation and real-world applicability,” Rahimi said in a news release. “From membraneless systems to scalable flow systems, we’re charting pathways to decarbonize hard-to-abate sectors and support the transition to a low-carbon economy.”

According to the researchers, the “A Membraneless Electrochemically Mediated Amine Regeneration for Carbon Capture” research paper marked the beginning of the team’s first focus. The research examined the replacement of costly ion-exchange membranes with gas diffusion electrodes. They found that the membranes were the most expensive part of the system, and they were also a major cause of performance issues and high maintenance costs.

The researchers achieved more than 90 percent CO2 removal (nearly 50 percent more than traditional approaches) by engineering the gas diffusion electrodes. According to PhD student and co-author of the paper Ahmad Hassan, the capture costs approximately $70 per metric ton of CO2, which is competitive with other innovative scrubbing techniques.

“By removing the membrane and the associated hardware, we’ve streamlined the EMAR workflow and dramatically cut energy use,” Hassan said in the news release. “This opens the door to retrofitting existing industrial exhaust systems with a compact, low-cost carbon capture module.”

The second breakthrough, published by PhD student Mohsen Afshari, displayed a reversible flow battery architecture that absorbs CO2 during charging and releases it upon discharge. The results suggested that the technology could potentially provide carbon removal and grid balancing when used with intermittent renewables, such as solar or wind power.

“Integrating carbon capture directly into a redox flow battery lets us tackle two challenges in one device,” Afshari said in the release. “Our front-cover feature highlights its potential to smooth out renewable generation while sequestering CO2.”
