Anthony Rose, the CEO of creative agency United By Design, is on a mission to brighten Houston’s urban spaces and improve the city’s air quality one carbon-absorbing mural at a time.

Rose originally founded United By Design, or UXD, in 2019 to connect muralists like himself and commercial businesses seeking to beautify their spaces and form brand identities. After creating vibrant murals for Lockhart Elementary School, the Houston Astros, and Smoothie King, Rose expanded UXD’s vision to include environmental sustainability in their artistic collaborations in 2022.

“This city’s vibrant art scene and growing focus on sustainability makes it an ideal location for our projects,” Rose says. “We’re not just creating eco-friendly murals, we’re reimagining how art can actively contribute to environmental solutions.”

In search of ecologically-conscious paints, Rose formed a partnership with Spain-based, natural paint company Graphenstone. Rose says he was drawn to the company’s eponymous Graphenstone coating because of its nontoxic ingredients and exclusively uses the product for UXD’s carbon-absorbing murals.

The Graphenstone coating consists of a limestone base which goes through a process called photocatalysis, during which carbon dioxide from the atmosphere is absorbed into the surface, and is then sealed in with graphene, a thin layer of carbon atoms. The murals absorb carbon dioxide throughout the coat’s drying process which typically takes 30 days.

“Each of our murals absorbs about 1600 grams of CO2 during that curing process which is the equivalent daily absorption of about 33 growing trees,” Rose explains.

UXD’s largest carbon-absorbing mural to date is a floor-to-ceiling panorama in downtown Houston’s historic Mellie Esperson building, home to the company’s new creative hub. Painted by Houston-born artist Emily Ding, the mural is a tribute to the establishment’s namesake: an innovative, early 20th century entrepreneur who constructed the opulent building.

Rose says UXD plans to expand their carbon-absorbing murals project in collaboration with more local artists and establishments, while creating an artist-in-residency program themed around sustainability. Though Rose acknowledges in the grand scheme of carbon pollution these murals are not a silver bullet, he says the non-toxic paints are encouraging conversations about how artists can be conservation-minded.

“We’re trying to figure out how art as a messaging tool can help break down scientific data, a language not many people practice daily, can break down barriers and help bridge the gap to a more intuitive knowledge of sustainability,” Rose says. “We’re bringing the community together, helping them feel empowered, and giving them actionable information to help them live more sustainable lives.”

Houston geothermal energy startup grows local office presence

report

On the heels of landing more than $240 million in venture capital, Houston-based geothermal power provider Fervo Energy has more than quadrupled the size of its headquarters.

Fervo previously occupied 5,158 square feet at 114 Main St. in downtown Houston. The company recently left the Main Street space and leased 23,782 square feet at downtown Houston’s 910 Louisiana office tower. Houston-based commercial real estate company Hines owns and manages the 50-story former One Shell Plaza.

“We believe Houston is the center of the energy transition, and downtown Houston has long been its center of activity,” Tim Latimer, co-founder and CEO of Fervo Energy, says in a news release. “The availability of dining options, parks, and biking infrastructure continue to be great assets and a huge draw for our team. For these reasons and more, the only place for Fervo’s headquarters is downtown Houston.”

In February 2024, Fervo announced it had raised $244 million in an investment round led by Oklahoma City, Oklahoma-based hydrocarbon exploration company Devon Energy. Fervo has collected $431 million in funding since its founding in 2017.

Energy companies like Fervo occupy about 43 percent of office space in downtown Houston, according to a new report from the Downtown Houston+ organization. Nineteen new tenants set up shop last year in downtown Houston, with 10 of them operating in the energy sector.

Other energy companies that recently leased office space in downtown Houston include:

  • AES Clean Energy
  • Axip Energy Services
  • EnLink Midstream
  • MRC Global
  • Repsol Renewables
  • Stonepeak

Solar farms are booming and putting thousands of hungry sheep to work

Solar Power

On rural Texas farmland, beneath hundreds of rows of solar panels, a troop of stocky sheep rummage through pasture, casually bumping into one another as they remain committed to a single task: chewing grass.

The booming solar industry has found an unlikely mascot in sheep as large-scale solar farms crop up across the U.S. and in the plain fields of Texas. In Milam County, outside Austin, SB Energy operates the fifth-largest solar project in the country, capable of generating 900 megawatts of power across 4,000 acres.

How do they manage all that grass? With the help of about 3,000 sheep, which are better suited than lawnmowers to fit between small crevices and chew away rain or shine.

The proliferation of sheep on solar farms is part of a broader trend — solar grazing — that has exploded alongside the solar industry.

Agrivoltaics, a method using land for both solar energy production and agriculture, is on the rise with more than 60 solar grazing projects in the U.S., according to the National Renewable Energy Laboratory. The American Solar Grazing Association says 27 states engage in the practice.

"The industry tends to rely on gas-powered mowers, which kind of contradicts the purpose of renewables," SB Energy asset manager James Hawkins said.

A sunny opportunity
Putting the animals to work on solar fields also provides some help to the sheep and wool market, which has struggled in recent years. The inventory of sheep and lamb in Texas fell to 655,000 in January 2024, a 4% drop from the previous year, according to the most recent figures from the U.S. Department of Agriculture.

Because solar fields use sunny, flat land that is often ideal for livestock grazing, the power plants have been used in coordination with farmers rather than against them.

Sheepherder JR Howard accidentally found himself in the middle of Texas' burgeoning clean energy transition. In 2021, he and his family began contracting with solar farms — sites with hundreds of thousands of solar modules — to use his sheep to eat the grass.

What was once a small business has turned into a full-scale operation with more than 8,000 sheep and 26 employees.

"Just the growth has been kind of crazy for us," said Howard, who named his company Texas Solar Sheep. "It's been great for me and my family."

Following the herd
Some agriculture experts say Howard's success reflects how solar farms have become a boon for some ranchers.

Reid Redden, a sheep farmer and solar vegetation manager in San Angelo, Texas, said a successful sheep business requires agricultural land that has become increasingly scarce.

"Solar grazing is probably the biggest opportunity that the sheep industry had in the United States in several generations," Redden said.

The response to solar grazing has been overwhelmingly positive in rural communities near South Texas solar farms where Redden raises sheep for sites to use, he said.

"I think it softens the blow of the big shock and awe of a big solar farm coming in," Redden said.

Fielding more research
Agrivoltaics itself isn't new. Solar farms are land-intensive and require a lot of space that could be used for food production. Agrivoltaics compensates by allowing the two to coexist, whether growing food or caring for livestock.

There is a lot still unknown about the full effects of solar grazing, said Nuria Gomez-Casanovas, an assistant professor in regenerative system ecology at Texas A&M University.

Not enough studies have been done to know the long-term environmental impacts, such as how viable the soil will be for future agriculture, although Gomez-Casanovas suspects solar grazing may improve sheep productivity because the panels provide shade and can be more cost-efficient than mowing.

"We really have more questions than answers," Gomez-Casanovas said. "There are studies that show that the land productivity is not higher versus solar alone or agriculture alone, so it's context-dependent."

As one of Texas' largest solar sheep operators, Howard has more clients than he can handle. He expects to add about 20 more employees by the end of this year, which would nearly double his current workforce. As for the sheep, he has enough already.

Chevron and partners to develop innovative power plants to support AI-focused data centers

power partners

Houston-based Chevron U.S.A. Inc., San Francisco investment firm Engine No. 1, and Boston electric service company GE Vernova have announced a partnership to create natural gas power plants in the United States. These plants support the increased demand for electricity at data centers, specifically those developing artificial intelligence solutions.

“The data centers needed to scale AI require massive amounts of 24/7 power. Meeting this demand is forecasted to require significant investment in power generation capacity, while managing carbon emissions and mitigating the risk of grid destabilization,” Chevron CEO Mike Wirth, shared in a LinkedIn post.

The companies say the plants, known as “power foundries,” are expected to deliver up to four gigawatts, equal to powering 3 million to 3.5 million U.S. homes, by the end of 2027, with possible project expansion. Their design will allow for the future integration of lower-carbon solutions, such as carbon capture and storage and renewable energy resources.

They are expected to leverage seven GE Vernova 7HA natural gas turbines, which will serve co-located data centers in the Southeast, Midwest and West. The exact locations have yet to be specified.

“Energy is the key to America’s AI dominance, “ Chris James, founder and chief investment officer of investment firm Engine No. 1, said in a news release. “By using abundant domestic natural gas to generate electricity directly connected to data centers, we can secure AI leadership, drive productivity gains across our economy and restore America’s standing as an industrial superpower. This partnership with Chevron and GE Vernova addresses the biggest energy challenge we face.”

According to the companies, the projects offer cost-effective and scalable solutions for growth in electrical demand while avoiding burdening the existing electrical grid. The companies plan to also use the foundries to sell surplus power to the U.S. power grid in the future.

DOE grants $13.7M tax credit to power Houston clean hydrogen project

power move

Permascand USA Inc., a subsidiary of Swedish manufacturing company Permascand, has been awarded a $13.7 million tax credit by the U.S. Department of Energy (DOE) to expand across the country, including a new clean hydrogen manufacturing facility in Houston.

The new Houston facility will manufacture high-performance electrodes from new and recycled materials.

"We are proud to receive the support of the U.S. Department of Energy within their objective for clean energy," Permascand CEO Fredrik Herlitz said in a news release. "Our mission is to provide electrochemical solutions for the global green transition … This proposed project leverages Permascand’s experience in advanced technologies and machinery and will employ a highly skilled workforce to support DOE’s initiative in lowering the levelized cost of hydrogen.”

The funding comes from the DOE’s Qualifying Advanced Energy Project Credit program, which focuses on clean energy manufacturing, recycling, industrial decarbonization and critical materials projects.

The Permascand proposal was one of 140 projects selected by the DOE with over 800 concept papers submitted last summer. The funding is part of $6 billion in tax credits in the second round of the Qualifying Advanced Energy Project Credit program that was deployed in January.

So far credits have been granted to approximately 250 projects across more than 40 states, with project investments over $44 billion dollars, according to the Department of Treasury. Read more here.
