Houston-led research team granted $4.1M for carbon synthesis project, calls for collaboration

fresh funding

A Rice University-led team of scientists has been awarded a $4.1 million grant to optimize a synthesis process that could make carbon materials sustainable and affordable on a large scale.

Known as carbon nanotube (CNT) synthesis, the process has the ability to create hollow cylindrical nanoscale structures made from carbon atoms that are strong, lightweight and carry heat and electricity well. CNT synthesis evolved across multiple countries around the same time, according to Rice. But to scale up the process in a way that could create alternatives to materials dependent on heavy industry, Matteo Pasquali, the team's leader and the A.J. Hartsook Professor of Chemical and Biomolecular Engineering, says collaboration will be required.

“We have to apply a collaborative mindset to solve this problem,” Pasquali says in a statement. “We believe that by bringing together a dedicated interdisciplinary community, this project will lead to improvements in reactor efficiency and help identify further gaps in instrumentation and modeling.”

The grant seeks to achieve that. The funds come from both Rice’s Carbon Hub, which contributed $2.2 million to the team, and The Kavli Foundation, which granted $1.9 million in the form of a Kavli Exploration Award in Nanoscience for Sustainability.

The Kavli Foundation supports research in astrophysics, nanoscience, neuroscience and theoretical physics. Winners of its Kavli Prize, which recognizes scientific breakthroughs, often go on to win the Nobel Prize.

“We are proud to partner with Rice University to support this important high-risk, high-reward research,” says Amy Bernard, director of life sciences at The Kavli Foundation, says in a statement.

Pasquali is the director and one of the creators of Rice's Carbon Hub, a collaborative group of corporations, researchers, universities and nonprofits focused on decarbonizing the economy. He says the grant will help the team develop tools to shed light on CNT formation and reaction zones.

“We are at a critical juncture in carbon research, and it is really important that we shed light on the physical and chemical processes that drive CNT synthesis,” Pasquali says. “Currently, reactors are black boxes, which prevents us from ramping up synthesis efficiency. We need to better understand the forces at play in CNT formation by developing new tools to shed light on the reaction zone and find ways to leverage it to our advantage.”

Boris Yakobson, the Karl F. Hasselmann Professor of Engineering and professor of materials science and nanoengineering at Rice, and Thomas Senftle, assistant professor of chemical and biomolecular engineering at Rice, are also involved in the project. Other collaborators hail from the UK, Italy, Korea, and Spain, as well as U.S. labs and universities, including Harvard, Stanford, MIT and others.

In October, a separate team of Rice researchers released a study on a new synthesis process with applications in developing commercially relevant solar cells.

Houston research shows how much hydrogen-powered vehicles would cost at the pump

hi, hydrogen

It's generally understood that transitioning away from gas-powered vehicles will help reduce the 230 million metric tons of carbon dioxide gas released each year by the transportation sector in Texas.

Now, researchers at the University of Houston are proposing that supplying hydrogen for transportation in the greater Houston area could also be profitable.

The research team has done the math. In a white paper, "Competitive Pricing of Hydrogen as an Economic Alternative to Gasoline and Diesel for the Houston Transportation Sector," the team compared three hydrogen generation processes—steam methane reforming (SMR), SMR with carbon capture (SMRCC), and electrolysis using grid electricity and water—and provided cost estimates and delivery models for each.

The team found that SMRCC hydrogen can be supplied at about $6.10 per kilogram of hydrogen at the pump, which they say is competitive and shows promise for hydrogen-powered fuel cell electric vehicles (FCEVs).

FCEVs refuel with hydrogen in five minutes and produce zero emissions, according to UH.

"This research underscores the transformative potential of hydrogen in the transportation sector,” Alexander Economides, a co-author on the study, UH alumnus and CEO Kiribex Inc., said in the statement. “Our findings indicate that hydrogen can be a cost-competitive and environmentally responsible choice for consumers, businesses, and policymakers in the greater Houston area."

Economides was joined on the paper by co-authors Christine Ehlig-Economides, professor and Hugh Roy and Lillie Cranz Cullen Distinguished University Chair at UH, and Paulo Liu, research associate in the Department of Petroleum Engineering at UH.

Additionally, the team says Houston is an ideal leader for this transition.

“(Houston) has more than sufficient water and commercial filtering systems to support hydrogen generation,” the study states. “Add to that the existing natural gas pipeline infrastructure, which makes hydrogen production and supply more cost effective and makes Houston ideal for transitioning from traditional vehicles to hydrogen-powered ones.”

The study also discusses tax incentives, consumer preferences, grid generation costs and many other details.

UH team unlocks innovative approach to pinpoint pollution factors

zooming in on emissions

A team of researchers at the University of Houston are using machine learning to help guide pollution fighting strategies.

As reported in the journal Environmental Pollution last month, the team used the SHAP algorithm of machine learning (a game theory approach) and the Positive Matrix Factorization to pinpoint what areas in Houston had the highest impact on emissions and how certain meteorological factors play into ozone formation.

The paper was authored by Delaney Nelson, a doctoral student at the Department of Earth and Atmospheric Sciences of UH, and Yunsoo Choi, corresponding author and professor of atmospheric chemistry, AI deep learning, air quality modeling and satellite remote sensing.

The team's research closely tracked nitrogen-based compound and volatile organic compound measurements from Texas Commission on Environmental Quality's monitoring stations in the Houston area. After importing measurements from The Lynchburg Ferry station in Houston's ship channel and the urban Milby Park station, the machine learning and SHAP analysis showed a chemically definitive difference between the two areas.

For example, at the industrial station, the most impactful sources of pollution were from oil and gas flaring/production. At the urban site n_decane and industrial emissions/evaporation had the most impact on ozone.

According to Nelson and Choi, this shows that the machine learning and SHAP analysis approach can be used to tailor more precise air quality management strategies in different areas based on the site's unique characteristics.

“Once we know the specific emission sources and factors, we can develop targeted strategies to reduce emissions, which will in turn reduce ozone in the air and make it healthier for everyone," Choi said in a statement.

“Pollution is a critical issue in Houston, where you have extreme high heat and high concentration of ozone in the summers. The types of insights we got are very useful information for the local community to develop effective policies. That’s why we put our time, effort and technological expertise into this project," he continued.

Next the team envisions applying their approach in different cities and across the country.

“Austin, San Antonio and Dallas all have different characteristics, so I expect (volatile organic compound) sources will also be different,” Choi said. “Identifying VOC sources in different cities is very important because each city should have its own unique pollution fighting strategy.”

This summer, the City of Houston released an updated report on its major strategies to combat climate change and build a more resilient future for its residents.

Researchers at the University of Houston are looking at an alternative way to capture carbon that uses a surprising conduit: algae.

In a newly published article in Green Chemistry, a journal of the Royal Society of Chemistry, Venkatesh Balan, associate professor of engineering technology at UH, details how he and his team are researching ways fresh- and salt-water phototropic organisms, or microalgae, can sequester carbon from industrial refineries and convert it into useful byproducts.

Balan is joined by UH researchers James Pierson and Hasan Husain, Sandeep Kimar from Old Dominion University, Christopher Saffron of Michigan State University, and Vinod Kumar from Cranfield University in the United Kingdom.

According to a release from UH, Balan and research assistant Masha Alian have uncovered how microalgae can produce fungus like lichen and create healthy food products. After microalge captures the carbon, it then converts that CO2 into mass-produced proteins, lipids and carbohydrates, according to the team's research.

“We are coming up with the alternate approach of using algae to fix the CO2 then using the carbon to make bioproducts that are useful to mankind,” Balan said in the release.

The method offers an alternative to other carbon capture options that aim to burry carbon, which is expensive and energy intensive, according to UH.

Balan says this research also has applications in wastewater treatment and the production of food, fertilizers, fuels and chemicals, all of which could lessen the dependency on fossil fuels in the future.

"On your table or in your pantry, you see food products. What’s harder to visualize are the greenhouse gasses emitted by the orchard that grows the fruit, the factory that makes the breakfast cereal, the transportation that brings the cookies to your neighborhood, even your own commute to buy the food," Balan said. "It adds up, but the problem is easy to ignore because we can’t see it. Yet all consumers contribute, in our own way, to the greenhouse effect.”

The UH team is just one of many Houston groups looking at unconventional, although natural ways to combat climate change.

In September, Rice University announced that two researchers were awarded a three-year grant from the Department of Energy for their research into the processes that allow soil to store roughly three times as much carbon as organic matter compared to Earth's atmosphere.

Houston research team develops breakthrough process for light-harvesting crystals in DOE-backed project

solar success

A team of Rice researchers have developed a breakthrough synthesis process for developing light-harvesting materials that can be used in solar cells to convert light into electricity.

Detailed in an October study in Nature Synthesis, the new process is able to more closely control the temperature and time of the crystallization process to create 2D halide perovskites with semiconductor layers of “ideal thickness and purity,” according to a release from Rice.

The process, known as kinetically controlled space confinement, was developed by Rice University chemical and biomolecular engineer Aditya Mohite, along with others at Northwestern University, the University of Pennsylvania and the University of Rennes. The research was backed by the Department of Energy, the Army Research Office, the National Science Foundation and a number of other organizations.

“This research breakthrough is critical for the synthesis of 2D perovskites, which hold the key to achieving commercially relevant stability for solar cells and for many other optoelectronic device applications and fundamental light matter interactions,” Mohite said in a statement.

Traditional synthesis methods for creating 2D halide perovskites, which have been shown to offer a high-performance low-cost way to produce solar cells, have generated uneven crystal growth when attempting to reach a higher n value. And uneven crystal growth can result in a less reliable material, while a high n value can result in higher electrical conductivity, among other benefits.

The study shows how the kinetically controlled space confinement method can gradually increase n values in 2D halide perovskites, which will assist in the production of crystals with a certain thickness.

“We designed a way to slow down the crystallization and tune each kinetics parameter gradually to hit the sweet spot for phase-pure synthesis,” Jin Hou, a Ph.D. student at Rice and a lead author on a study, said in a statement.

The process is expected to improve the stability and lower the costs of emerging technologies in optoelectronics, or the study and application of light-emitting or light-detecting devices, and photovoltaics, the conversion of thermal energy into electricity.

"This work pushes the boundaries of higher quantum well 2D perovskites synthesis, making them a viable and stable option for a variety of applications,” Hou added.

Houston universities have been making major strides relating to crystallization processes in recent months.

In September, the University of Houston announced The Welch Foundation awarded its inaugural $5 million Catalyst for Discovery Program Grant to establish the Welch Center for Advanced Bioactive Materials Crystallization. The center will build upon UH professor Jeffrey Rimer's work relating to the use of crystals to help treat malaria and kidney stones.

Over the summer, a team of researchers at UH also published a paper detailing their discovery of how to use molecular crystals to capture large quantities of iodine, one of the most common products of radioactive fission, which is used to create nuclear energy.

Oxy subsidiary secures Microsoft as largest-ever DAC carbon removal credit customer

major move

Occidental Petroleum’s Houston-based carbon capture, utilization and, sequestration (CCUS) subsidiary, 1PointFive, has inked a six-year deal to sell 500,000 metric tons of carbon dioxide removal credits to software giant Microsoft.

In a news release, 1Point5 says this agreement represents the largest-ever single purchase of carbon credits enabled by direct air capture (DAC). DAC technology pulls CO2 from the air at any location, not just where carbon dioxide is emitted.

Under the agreement, the carbon dioxide that underlies the credits will be stored in a below-the-surface saline aquifer and won’t be used to produce oil or gas.

“A commitment of this magnitude further demonstrates how one of the world’s largest corporations is integrating scalable [DAC] into its net-zero strategy,” says Michael Avery, president and general manager of 1PointFive. “Energy demand across the technology industry is increasing, and we believe [DAC] is uniquely suited to remove residual emissions and further climate goals.”

Brian Marrs, senior director for carbon removal and energy at Microsoft, says DAC plays a key role in Microsoft’s effort to become carbon-negative by 2030.

The carbon dioxide will be stored at 1PointFive’s first industrial-scale DAC plant, being built near Odessa. The $1.3 billion Stratos project, which 1Point5 is developing through a joint venture with investment manager BlackRock, is designed to capture up to 500,000 metric tons of CO2 per year.

The facility is scheduled to open in mid-2025.

Aside from Microsoft, organizations that have agreed to buy carbon removal credits from 1Point5 include Amazon, Airbus, All Nippon Airways, the Houston Astros, the Houston Texans, and TD Bank.

Occidental says 1PointFive plans to set up more than 100 DAC facilities worldwide by 2035.

Texas Gov. Greg Abbott demands answers from Houston power company following Beryl

investigation incoming

With around 270,000 homes and businesses still without power in the Houston area almost a week after Hurricane Beryl hit Texas, Gov. Greg Abbott on Sunday said he's demanding an investigation into the response of the utility that serves the area as well as answers about its preparations for upcoming storms.

“Power companies along the Gulf Coast must be prepared to deal with hurricanes, to state the obvious,” Abbott said at his first news conference about Beryl since returning to the state from an economic development trip to Asia.

While CenterPoint Energy has restored power to about 2 million customers since the storm hit on July 8, the slow pace of recovery has put the utility, which provides electricity to the nation’s fourth-largest city, under mounting scrutiny over whether it was sufficiently prepared for the storm that left people without air conditioning in the searing summer heat.

Abbott said he was sending a letter to the Public Utility Commission of Texas requiring it to investigate why restoration has taken so long and what must be done to fix it. In the Houston area, Beryl toppled transmission lines, uprooted trees and snapped branches that crashed into power lines.

With months of hurricane season left, Abbott said he's giving CenterPoint until the end of the month to specify what it'll be doing to reduce or eliminate power outages in the event of another storm. He said that will include the company providing detailed plans to remove vegetation that still threatens power lines.

Abbott also said that CenterPoint didn't have “an adequate number of workers pre-staged" before the storm hit.

Following Abbott's news conference, CenterPoint said its top priority was “power to the remaining impacted customers as safely and quickly as possible,” adding that on Monday, the utility expects to have restored power to 90% of its customers. CenterPoint said it was committed to working with state and local leaders and to doing a “thorough review of our response.”

CenterPoint also said Sunday that it’s been “investing for years” to strengthen the area’s resilience to such storms.

The utility has defended its preparation for the storm and said that it has brought in about 12,000 additional workers from outside Houston. It has said it would have been unsafe to preposition those workers inside the predicted storm impact area before Beryl made landfall.

Brad Tutunjian, vice president for regulatory policy for CenterPoint Energy, said last week that the extensive damage to trees and power poles hampered the ability to restore power quickly.

A post Sunday on CenterPoint's website from its president and CEO, Jason Wells, said that over 2,100 utility poles were damaged during the storm and over 18,600 trees had to be removed from power lines, which impacted over 75% of the utility's distribution circuits.

Things to know: Beryl in the rearview, Devon Energy's big deal, and events not to miss

taking notes

Editor's note: Dive headfirst into the new week with three quick things to catch up on in Houston's energy transition.

Hurricane Beryl's big impact

Hundreds of thousands of people in the Houston area likely won’t have power restored until this week, as the city swelters in the aftermath of Hurricane Beryl.

The storm slammed into Texas on July 8, knocking out power to nearly 2.7 million homes and businesses and leaving huge swaths of the region in the dark and without air conditioning in the searing summer heat.

Although repairs have restored power to nearly 1.4 million customers, the scale of the damage and slow pace of recovery has put CenterPoint Energy, which provides electricity to the nation's fourth-largest city, under mounting scrutiny over whether it was sufficiently prepared for the storm and is doing enough now to make things right.

Some frustrated residents have also questioned why a part of the country that is all too familiar with major storms has been hobbled by a Category 1 hurricane, which is the weakest kind. But a storm's wind speed, alone, doesn't determine how dangerous it can be. Click here to continue reading this article from the AP.

Big deal: Devon Energy to acquire Houston exploration, production biz in $5B deal

Devon Energy is buying Grayson Mill Energy's Williston Basin business in a cash-and-stock deal valued at $5 billion as consolidation in the oil and gas sector ramps up.

The transaction includes $3.25 billion in cash and $1.75 billion in stock.

Grayson Mill Energy, based in Houston, is an oil and gas exploration company that received an initial investment from private equity firm EnCap Investments in 2016.

The firm appears to be stepping back from energy sector as it sells off assets. Last month EnCap-backed XCL Resources sold its Uinta Basin oil and gas assets to SM Energy Co. and Northern Oil and Gas in a transaction totaling $2.55 billion. EnCap had another deal in June as well, selling some assets to Matador Resources for nearly $2 billion. Click here to continue reading.
