The University of Houston recently completed assessments on year one of the first mass timber project on campus, and the results show it has had a major impact.

Known as the Retail, Auxiliary, and Dining Center, or RAD Center, the $44 million building showed an 84 percent reduction in predicted energy use intensity, a measure of how much energy a building uses relative to its size, compared to similar buildings. Its Global Warming Potential rating, a ratio determined by the Intergovernmental Panel on Climate Change, shows a 39 percent reduction compared to the benchmark for other buildings of its type.

In comparison to similar structures, the RAD Center saved the equivalent of taking 472 gasoline-powered cars driven for one year off the road, according to architecture firm Perkins & Will.

The RAD Center was created in alignment with the AIA 2030 Commitment to carbon-neutral buildings, designed by Perkins & Will and constructed by Houston-based general contractor Turner Construction.

Perkins & Will’s work reduced the building's carbon footprint by incorporating lighter mass timber structural systems, which allowed the RAD Center to reuse the foundation, columns and beams of the building it replaced. Reused elements account for 45 percent of the RAD Center’s total mass, according to Perkins & Will.

Mass timber is considered a sustainable alternative to steel and concrete construction. The RAD Center, a 41,000-square-foot development, replaced the once popular Satellite, which was a food, retail and hangout center for students on UH’s campus near the Science & Research Building 2 and the Jack J. Valenti School of Communication.

The RAD Center uses more than a million pounds of timber, which can store over 650 metric tons of CO2. Aesthetically, the building complements the surrounding campus woodlands and offers students a view both inside and out.

“Spaces are designed to create a sense of serenity and calm in an ecologically-minded environment,” Diego Rozo, a senior project manager and associate principal at Perkins & Will, said in a news release. “They were conceptually inspired by the notion of ‘unleashing the senses’ – the design celebrating different sights, sounds, smells and tastes alongside the tactile nature of the timber.”

In addition to its mass timber design, the building was also part of an Energy Use Intensity (EUI) reduction effort. It features high-performance insulation and barriers, natural light to illuminate a building's interior, efficient indoor lighting fixtures, and optimized equipment, including HVAC systems.

The RAD Center officially opened Phase I in spring 2024. The third and final phase of construction is scheduled for this summer, with a planned opening set for the fall.

Houston entrepreneur launches new venture to shine light on sustainability

texas innovator

A Houston nuclear engineer and entrepreneur wants consumers to capture their own ray of sunlight to brighten the prospect of making clean energy a bigger part of the power grid.

Solar Slice Founder Nathan Childress says his new venture offers a fulfilling way to encourage and promote solar energy and a greener planet. An experienced entrepreneur, Childress also serves as founder and CEO of technology software company Macorva.

Although trained in nuclear power plant design, solar power drew his interest as a cheaper and more accessible alternative, and Childress tells InnovationMap that he thinks that the transition to cleaner energy, in Texas especially, needs to step up.

With energy demand skyrocketing, and the push toward renewable solutions, solar seems like a safe bet for Childress, a former competitive high-stakes poker player. Childress cites a recent Yale University study that says 63 percent of Americans “feel a personal responsibility to help reduce global warming.”

But some studies show that 80 to 90 percent of the money invested into fighting climate change “aren’t going to things that people actually consider helpful,” he says.

“They’re more just projects that sound good, that are not actually taking any action,” says Childress, who has called Houston home for 25 years. He received his doctorate in medical physics at M.D. Anderson Cancer Center, where he worked on software that provided radiation therapy for patients.

The initial Kickstarter fundraising round, which will be launched soon, will finance the construction of one utility-scale solar farm, on about five to 10 acres, which would produce about 1 megawatt, or 1,000 kilowatts, of clean energy. The plant would make enough energy to power about 200 average homes.

Childress says interest has been strong, with several thousand signed up on the Kickstarter launch list. Some who are signed up expressed interest in a subscription, he said, and that may be offered later. Initially, though, for a one-time purchase of $95, a Solar Slice client can purchase one virtual 50W slice of solar power, produced by the farm. Over its lifetime, Childress says, that one purchase can offset three tons of carbon dioxide.

The app tracks carbon offsetting, and energy production for the slice, showing a client “exactly how much I have helped the climate, here’s exactly how (many) emissions I have prevented from putting in the atmosphere,” he says.

The energy produced by five slices can offset the average American’s carbon footprint for a year, and the power generated by the solar farm will be sold to the electric grid. As clients purchase more slices, they can earn eco-credits to donate to other climate-friendly partners, to plant trees or create pollinator habitats.

While Solar Slice is a for-profit venture, contributors won’t get rich or even make money from their purchase. Rather, it provides validation.

“Our focus is maximizing the real world impact, not for financial gain. This is not something people sign up (for) to make money. We’re really clear about that,” Childress says. “I want to show that it’s possible to have a for-profit company that is sustainable, that does good work.

“And hopefully, we can be part of the spirit…for a bigger movement, and for consumers and business, especially, to do things that matter.”

The largest U.S. solar plants are in Nevada and California, and those states are sites under consideration, but Childress says Texas is the most likely home for the initial project. The ten largest utility-scale solar plants in Texas by capacity are all in far west or central parts of the state, according to the state comptroller’s office.

Childress has a team of four, who are handling the marketing, plant design and site scouting, and hopes to hire five to 10 more, depending on response and growth. He says the Solar Slice consumer can directly connect in real time to the contribution that their purchase will make toward a green energy future.

“That was our inspiration..let’s start something that is really making a difference..and making really clear to the individuals what’s being done,” he says.

Solar energy has become a growing source of power for Texas, comprising about 6 percent of the state’s energy generation, as of 2022, the comptroller’s office says.

The state ranks first in projected growth of solar energy over the next five years, with more than 9,500 operating solar plants, and many thousands more announced, according to the state Public Utility Commission.

“We would absolutely love to make this into something where we are building plants around the nation, around the world,” Childress he says.

However, resistance to alternative energy projects like solar and wind, especially on a large scale, remains in some quarters.

Obtaining site permits for swaths of land can be also a challenge. For example, a recent survey by Berkeley Lab of 123 professionals from 62 unique, large-scale wind and solar energy facilities showed that about one-third of wind and solar siting applications in the past five years were canceled.

Half of the projects experienced delays of six months or longer. And according to the survey, developers expect the trend to continue, and become more expensive to address.

However, another Berkeley Lab survey of residents who live within three miles of a solar power plant showed that most view the plant positively. The larger the plant, the more negative the response in the survey. The smaller the farm, the more positive the reactions.

Childress says many of the common objections to utility-scale solar farms are misguided, and incorrect. For example, the concern that they would take over available farmland or take up too much space.

He says that even if the entire U.S. power grid relied solely on solar power, the plants would occupy not even a half percent of available land, which is about one percent farmland.

up and running

Houston-based Phillips 66 announced the full conversion of a California renewable energy facility.

The Rodeo Renewable Energy Complex will expand commercial-scale production to “position the company as a leader in renewable fuels,” according to a news release.

The facility, located 200 miles south of San Francisco, California, increased rates to approximately 50,000 barrels per day (or 800 million gallons per year), which reached the company’s goal of achieving full capacity by the second quarter of 2024. This also aligns with its commitment to energy transition and provide customers with lower-carbon solutions.

The Rodeo complex has new pre-treatment units that process lower carbon intensity feedstocks like cooking oil, fats, greases and vegetable oil. It began producing approximately 30,000 barrels per day of renewable fuel at the end of the first quarter of 2024. Rodeo Renewed is designed to produce renewable diesel and sustainable aviation fuel, and was started in 2020, and mostly serves the West Coast and California areas.

“Phillips 66 has reached another important milestone, which is a testament to our employees’ dedication to achieving our company’s strategic priorities,” executive vice president of Refining Rich Harbison said in a news release. “The facility running at full capacity supports the growing demand for renewable fuels, lowers our carbon footprint and creates long-term value for our shareholders.”

Houston company breaks ground on North Texas solar project

coming soon

A Houston-area company has broken ground on a new 310-megawatt solar project located in Bosque County, Texas.

League City-based INEOS Olefins & Polymers and Florida-based NextEra Energy Resources announced the groundbreaking on INEOS Hickerson Solar, which will reportedly save over 310,000 tons of CO2 every year.

“INEOS O&P USA is committed to leading the petrochemical community in adopting renewable energy solutions,” says CEO Mike Nagle in a news release. “This solar project is a crucial step in our global efforts to reduce the carbon footprint of INEOS businesses.”

The INEOS Hickerson Solar project will be constructed, owned and operated by a subsidiary of NextEra Energy Resources, and the output will aim to cover the net purchased electricity load for all 14 of INEOS O&P USA’s manufacturing, fractionation and storage facilities. Commercial operation is expected by December 2025.

The project is expected to produce 730,000 megawatt-hours of clean energy annually, which is the equivalent to the annual electricity use of over 68,000 homes. INEOS hopes this will significantly contribute to reducing greenhouse gas emissions by approximately 310,000 tons per year.

This follows the recently signed renewable power purchase agreement with NextEra Energy Resources, which is the world's largest generator of renewable energy from wind and sun.

This Earth Week, let's consider the benefits of home charging for electric vehicles. Photo via Getty Images

Expert: 5 ways residential charging enhances the environmental benefits of EVs

guest column

Electric vehicles are already considered as an environmentally conscientious alternative to traditional internal combustion engine vehicles, thanks to their zero tailpipe emissions. However, the environmental benefits of EVs can be further enhanced by implementing a home-base charging routine.

This is important not only for individuals looking to cut their household’s carbon footprint, but also for corporations that operate EV fleets and are looking for additional cost and environmental savings as part of their larger sustainability initiatives. What makes home charging the most eco-conscious option?

1. Increased use of renewable energy

More than 4 million homes in the United States support rooftop solar panels that provide renewable energy back to the property or back to the local grid. When EV owners install solar panels or other renewable energy systems at their homes, they can charge their vehicles using this clean energy, effectively reducing the carbon footprint associated with their EV use to nearly zero. This direct use of renewables circumvents the inefficiencies and emissions associated with the broader energy grid which, depending on the location, may still rely on fossil fuels to a significant extent. This synergy between EVs and clean local energy production is exemplified by Tesla’s solar roof program, which promotes the adoption of clean home-based energy production as part of the holistic EV ownership experience offered through their app.

2. Optimizing charging times for lower emissions

Home charging allows for more flexible and strategic charging schedules. EV owners can often take advantage of off-peak electricity rates and lower carbon intensity periods by charging their vehicles overnight or when renewable energy production (such as wind or solar power) is at its peak. This not only leads to cost savings for the consumer, but also contributes to a balanced demand on the electric grid, reducing the need for high-carbon emergency power sources that are sometimes activated during peak demand times. Apps like WhenToPlugIn use a carbon intensity forecasting tool to help consumers pick the best times to charge.

3. Reducing dependency on public charging infrastructure

Public charging stations are crucial for long-distance EV travel. For everyday use, the current public charging landscape is trailing the demand curve. The good news is that the majority of EV drivers can rely almost solely on home charging. This practice ensures public charging spots remain open for those who, due to circumstances such as residing in multi-unit dwellings without charging facilities, cannot charge at home. Consequently, this accessibility supports wider adoption of EVs, leading to a more substantial reduction in overall emissions.

4. Avoiding unnecessary travel to public charging stations

The average driver has to detour 2 miles to refill their gas tank. For electric vehicles, finding an available public charger can add many more miles to a trip. Home charging ensures that EVs can start each day with a “full tank” — which, with new EVs, means hundreds of miles of range before needing to plug in again. This reduction in driven miles not only saves time but also decreases the energy consumption and emissions associated with traveling to and from charging stations unnecessarily. By charging at home, EV owners can ensure their vehicles are ready to go without extra trips, further cutting down on the vehicle's overall environmental impact.

5. Enhancing battery longevity

Charging at home typically involves slower charging speeds compared to rapid chargers found in public stations. These slower, more controlled charging rates are less taxing on an EV's battery, contributing to longer battery life and better overall efficiency. Longer battery lifespans mean fewer replacements over the vehicle's life, significantly reducing the environmental impact associated with battery production and disposal. This not only has clear environmental benefits but also economic ones for the vehicle owner.

Conclusion

The environmental benefits of electric vehicles are well-documented, but by incorporating home charging, these benefits are amplified significantly. Through the increased use of renewable energy, optimizing charging times to utilize green power, and reducing reliance on public charging infrastructure, EV owners can further reduce their environmental footprint. As technology advances and the energy grid becomes cleaner, the potential for home charging to contribute to a more sustainable future only grows, reinforcing the role of electric vehicles in the transition to greener transportation options.

plugging into LNG

Texas LNG, a four million tonnes per annum liquefied natural gas export terminal to be constructed in the Port of Brownsville, and a subsidiary of Glenfarne Energy Transition, announced the selection of its new partner.

Gulf LNG Tugs of Texas will operate, build, and deliver tugboats under an agreement to assist LNG carriers arriving at the facility. Tugs of Texas is part of a consortium of Suderman & Young Towing Co., Bay-Houston Towing, and Moran Towing Corp., and the tugboats will be among the “most modern, low-emissions tugboats available to serve a facility of Texas LNG’s size” according to the company. This will also align with Texas LNG’s "Green by Design" approach, and the deal is a long-term agreement.

The projected port for Texas LNG is considered to be an area with consistent operating temperatures, and reliable maritime operations with lower probability of impact from inclement weather like storms and damage associated with them. Globally, Texas LNG is also designed to be one of the lowest-emitting export terminals. Texas LNG is developing the project site on the north shore of the Port of Brownsville. This area offers access to a deep-water ship channel in close proximity to the Gulf of Mexico and the Panama Canal.

“Gulf LNG Tugs is excited to be providing marine services in a long-term partnership with Texas LNG,” the companies say in a joint statement. “We are proud to be the exclusive tug operator for LNG vessels to yet another successful LNG project in the Port of Brownsville and look forward to expanding our operations in the port and our presence in the Rio Grande Valley community."

Houston has its stamp on the project in multiple ways with Gulf LNG Tugs boasting two Houston area companies in Bay-Houston Management LLC and Suderman & Young Towing Company.

New York and Houston-based Glenfarne works to provide solutions to lower the world’s carbon footprint, which aligns with the common goals of all the companies involved.

“The Texas LNG team undertook a comprehensive process to identify a marine service provider that not only matches our commitment to environmental stewardship, but also provides our customers with reliable, cost-effective marine services,” Brendan Duval, CEO and Founder of Glenfarne Energy Transition said in a news release. “We are pleased to have Gulf LNG Tugs on board as a partner and look forward to the jobs and local content they will bring to both Texas LNG and the local Rio Grande Valley community."

Texas LNG recently announced that it signed a Heads of Agreement with EQT Corporation for natural gas liquefaction services for 0.5 MTPA of LNG, in addition to partnerships with Baker Hughes and ABB to help develop the terminal. This represents equipment selections for Texas LNG to date that is worth half a billion dollars’ worth.

Construction is slated to begin this year after the financing of the project is finalized.

Chevron CEO touts biofuels as part of its renewable energy efforts

Betting on biofuels

As Chevron Chairman and CEO Mike Wirth surveys the renewable energy landscape, he sees the most potential in biofuels.

At a recent WSJ CEO Council event, Wirth put a particular emphasis on biofuels—the most established form of renewable energy—among the mix of low-carbon energy sources. According to Biofuels International, Chevron operates nine biorefineries around the world.

Biofuels are made from fats and oils, such as canola oil, soybean oil and used cooking oil.

At Chevron’s renewable diesel plant in Geismar, Louisiana, a recent expansion boosted annual production by 278 percent — from 90 million gallons to 340 million gallons. To drive innovation in the low-carbon-fuels sector, Chevron opened a technology center this summer at its renewable energy campus in Ames, Iowa.

Across the board, Chevron has earmarked $8 billion to advance its low-carbon business by 2028.

In addition to biofuels, Chevron’s low-carbon strategy includes hydrogen, although Wirth said hydrogen “is proving to be very difficult” because “you’re fighting the laws of thermodynamics.”

Nonetheless, Chevron is heavily invested in the hydrogen market:

As for geothermal energy, Wirth said it shows “some real promise.” Chevron’s plans for this segment of the renewable energy industry include a 20-megawatt geothermal pilot project in Northern California, according to the California Community Choice Association. The project is part of an initiative that aims to eventually produce 600 megawatts of geothermal energy.

What about solar and wind power?

“We start with things where we have some reason to believe we can create shareholder value, where we’ve got skills and competency, so we didn’t go into wind or solar because we’re not a turbine manufacturer installing wind and solar,” he said in remarks reported by The Wall Street Journal.

In a September interview with The New York Times, Wirth touched on Chevron’s green energy capabilities.

“We are investing in new technologies, like hydrogen, carbon capture and storage, lithium and renewable fuels,” Wirth said. “They are growing fast but off a very small base. We need to do things that meet demand as it exists and then evolve as demand evolves.”
