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.”

Houston superconductor tech manufacturer raises $25M

fresh funding

A Houston company has closed its series B extension at $25 million.

MetOx International, which develops and manufactures high-temperature superconducting (HTS) wire, announced it closed a $25 million series B extension. Centaurus Capital, an energy-focused family office, and New System Ventures, a climate and energy transition-focused venture firm, led the round with participation from other investors.

"MetOx has developed a robust and highly scalable operation, and we are thrilled to partner with the Company as it enters this pivotal growth stage," says John Arnold, founder of Centaurus, in a news release. "The market for HTS is expanding at an unprecedented pace, with demand for HTS far outweighing supply. MetOx is poised to be the leading U.S. HTS producer, closing the supply gap and bringing dramatic capacity to high power innovations and applications. Their progress and potential are unmatched in the field, and we are proud to support their growth."

The fresh funding will go toward advancing the company's Xeus HTS wire technology for key energy transition applications by expanding MetOx's U.S.-based manufacturing capabilities to meet demand.

"This funding marks a pivotal step in our mission to revolutionize the energy and technology sectors with our advanced power delivery technology and accelerate delivery for our customers and partners. HTS is critical to enhancing the efficiency of our electric grid and enabling technological developments that, in many cases, would not be viable or even possible without superconductor technology," adds Bud Vos, CEO of MetOx. "Support from investors such as Centaurus and NSV not only provides the financial resources and strategic support required for accelerated scaleup, but also validates the broad reach of our technology across energy, data center, medical, and defense industries."

HTS wire technology is critical for the energy transition, especially amid rising data center growth, and for next generation wind turbines and interconnections.

MetOx's technology originated out of the University of Houston and was founded in 1998 by Alex Ignatiev, UH professor emeritus of physics and a fellow of the National Academy of Inventors. Last year, the company secured $3 million in funding from the U.S. Department of Energy to support the advancement of its proprietary manufacturing technology for its HTS wire.

"MetOx's HTS technology aligns with our systems-level research and offers a unique opportunity to dramatically accelerate the energy transition," says Ian Samuels, founder and managing partner at NSV. "MetOx's Xeus wire stands to be a force multiplier in clean energy generation and high-power transmission and distribution, enabling load growth and the deployment of power-dense data centers. NSV is excited to support MetOx as it scales domestic manufacturing capacity."

Houston VC conference returns to prioritize decarbonization, curated connections

can't miss event

In two weeks, hundreds of investors, corporate partners, and startups will convene to tackle topics of decarbonization, innovation, and investment. The annual event is also prioritizing something this year — connections.

In its third year, Venture Houston — taking place on Rice University's campus on September 7 — has a theme of "decarbonization in a digital world," but that's not the only thing different this year. The one-day conference has added on a unique event on September 6 to help engage around 50 investors with over 100 Houston startups.

The new activation is called Capital Connect, and HX Venture Fund will matchmake investors and startups for one-on-one meetings meant to spur collisions and collaboration.

"It's not a pitch competition — it doesn't have the stress of that," Sandy Guitar, general partner of HX Venture Fund, tells InnovationMap. "It's really just a way of connecting with a longer term horizon. We didn't want to limit it just to those who are currently raising, but actually include people who maybe just raised six months ago or are not going to raise for 12 more months, but might still want to be in the room."

The official day of the conference will also feature networking opportunities, including a breakfast hosted by DivInc, as well as networking breaks throughout the day.

"Based on feedback we received last year, networking was one of the things that was most celebrated about Venture Houston 2022," Guitar says. "All that space and time — the opportunity to allow people just to connect with one another. So, we're making sure that's a key part of this year as well."

Last year's keynote panel featured Gwyneth Paltrow, who shared her own founder's journey on the Venture Houston stage. This year's keynote address will be with Carmichael Roberts, investment committee co-lead of Breakthrough Energy Ventures, which was founded by Bill Gates to support climate change innovation.

While the topic of decarbonization might sound narrow, Guitar emphasizes that this event will not just be for the energy industry. Business everywhere — but especially in Houston — has an increased calling to decarbonization.

"I do think it's important to see the decarbonization not as a hard tech event, but as everything that touches carbon, which is basically everything in our planet in just the coal previously," she says. "Everything we make and use touches the climate."

Guitar adds that HXVF expects a crowd of around 1,000 people to attend the event this year, which would make it one of the largest VC-focused events ever to be held in the region. InnovationMap and EnergyCapital are media partners for the event.

Major corporation opens hub for global decarbonization in Houston

seeing green

Management consulting giant McKinsey & Co. plans to spend $100 million over the next decade to pump up Houston’s decarbonization economy.

McKinsey says the initiative will, among other things, focus on:

  • Promoting innovations like carbon capture, utilization, and storage (CCUS) and green hydrogen
  • Revamping business models for carbon-heavy companies
  • Ramping up the community of local startups involved in energy transition
  • Developing talent to work on decarbonization

As part of this program, McKinsey has set up a decarbonization hub in its Houston office, at 609 Main St.

“Decarbonization will lead to a new chapter of economic development, while also addressing a critical problem of climate change,” McKinsey partner Nikhil Ati says.

Global decarbonization efforts over the next three decades will require a $100 trillion investment, according to Utility Dive. Houston, home to 40 percent of publicly traded oil and gas companies, stands to gain a substantial share of that opportunity.

McKinsey’s Houston office has worked for several years on Houston’s energy transition initiatives. For instance, the firm helped produce a study and a whitepaper on energy transition here. The whitepaper outlines Houston’s future as the “epicenter of a global clean hydrogen hub.”

“Texas is the nation’s largest renewable energy producer, home to half of the nation’s hydrogen pipelines, and its companies have unparalleled capabilities in building and operating complex projects,” McKinsey senior partner Filipe Barbosa says. “This is Houston’s moment in time on the global stage.”

McKinsey estimates a Houston-based global hub for clean hydrogen that’s in place by 2050 could generate 180,000 jobs and create an economic impact of $100 billion.
