Engie to add 'precycling' agreements for forthcoming solar projects

reduce, reuse

Houston-based Engie North America has partnered with Arizona-based Solarcycle to recycle 1 million solar panels on forthcoming projects with a goal of achieving project circularity.

The collaboration allows Engie to incorporate "precycling" provisions into power purchase agreements made on 375 megawatts worth of projects in the Midwest, which are expected to be completed in the next few years, according to a news release from Engie.

Engie will use Solarcycle's advanced tracking capabilities to ensure that every panel on the selected projects is recycled once it reaches its end of life, and that the recovered materials are returned to the supply chain.

Additionally, all construction waste and system components for the selected projects will be recycled "to the maximum degree possible," according to Engie.

“We are delighted to bring this innovative approach to life. Our collaboration with Solarcycle demonstrates the shared commitment we have to the long-term sustainability of our industry,” Caroline Mead, SVP power marketing at ENGIE North America, said in the release.

Solarcyle, which repairs, refurbishes, reuses and recycles solar power systems, estimates that the collaboration and new provisions will help divert 48 million pounds of material from landfills and avoid 33,000 tons of carbon emissions.

“ENGIE’s precycling provision sets a new precedent for the utility-scale solar industry by proving that circular economy principles can be achieved without complex regulatory intervention and in a way that doesn’t require an up-front payment," Jesse Simons, co-founder and chief commercial officer at SOLARCYCLE, added in the release. "We’re happy to work creatively with leaders like ENGIE to support their commitment to circularity, domestic energy, and sustainability.”

TotalEnergies powers up its largest utility-scale solar farms in Texas

ready to shine

TotalEnergies has begun the commercial operations of two utility-scale solar farms with integrated battery storage located in southeast Texas.

The two farms are located in Cottonwood and Danish Fields, which is TotalEnergies’ largest solar farm in the United States.

“The start-ups of Danish Fields and Cottonwood in the fast-growing ERCOT market showcase TotalEnergies’ ability to deliver competitive renewable electricity to support our clients’ decarbonization goals, as well as our own,” Olivier Jouny, senior vice president of renewables at TotalEnergies, says in a news release.

The new projects have a combined capacity of 1.2 gigawatts. They are part of a portfolio of renewable assets totaling 4 gigawatts in operation or under construction currently in Texas. Danish Fields holds a capacity of 720 megawatts peak and 1.4 million ground-mounted photovoltaic panels.

Cottonwood, with a capacity of 455 megawatts peak featuring over 847,000 ground-mounted photovoltaic panels, will also feature 225 megawatt hours of battery storage supplied by Saft. This is scheduled for commissioning in 2025. The electricity production is contracted under long-term PPAs indexed to “merchant prices through an upside-sharing mechanism with LyondellBasell and Saint-Gobain,” per thenews release. The deal is to help support the companies’ decarbonization efforts.

Seventy percent of Danish’s solar capacity has been contracted through long-term Corporate Power Purchase Agreements signed with Saint-Gobain, which feature an upside sharing mechanism indexed on merchant price. The other 30 percent is intended to support the decarbonization of TotalEnergies’ industrial plants in the Gulf Coast region. The projects will cover the electricity consumption of TotalEnergies’ industrial sites in Port Arthur and La Porte in Texas, and Carville in Louisiana, which include Myrtle Solar that was commissioned in 2023 and the under-construction Hill 1 solar farm.

In addition to the solar farms, TotalEnergies has also added 1.5 gigawatt of flexible power production capacity with three gas-fired power plants they acquired in Texas.

“Thanks to these projects, we are delighted to take another step in delivering our strategy across the entire value chain, from power generation to customer delivery, in order to achieve our profitability target of 12 (percent return on average capital employed) in our Integrated Power business,” Jouny adds in the release.

Texas passes California on national report of top solar states

by the numbers

For the first time, Texas has passed California in the second quarter of 2024 to become the top solar state in the country.

The American Clean Power Association's quarterly market report found that, by adding 3,293 megawatts of new solar year-to-date, Texas has the most utility-scale solar capacity installed, comprising 20 percent of the overall U.S. solar fleet. The American Clean Power Association, which represents over 800 energy storage, wind, utility-scale solar, transmission, and clean hydrogen companies, found that Texas is home to 21,932 megawatts of capacity,

By utilizing clean energy initiatives, Texas included 1.6 gigawatts of new solar, 574 megawatts of storage, and 366 megawatts of onshore wind. With more than 28,000 megawatts, Texas had the highest volume of clean power development capacity in the second quarter. About 163,000 megawatts of capacity overall are in the works throughout the United States. Texas ranks No. 1 for total operating wind capacity and total operating solar capacity, and comes in second for operating storage capacity.

Texas again led in production levels with clean power construction projects nationally, which boasts more than 19,000 megawatts worth of clean power energy currently under construction. With almost 28.3 gigawatts in advanced development or under construction, Texas continues to come in at No.1, as California is next with over 16.4 gigawatts in the state’s project pipeline.

California added more than 1,900 megawatts of new clean power capacity in the second quarter, with its clean energy development behavior leaning more towards adding storage, which amounts to 60 percent of California’s year-to-date clean power installations.

According to the report from SmartAsset, the Lone Star State has the most clean energy capacity at 56,405 megawatts due to its sheer size for solar capacity, but continues to trail states with similar geographic characteristics in overall clean energy prevalence.

Another report published by the U.S. Energy Information Administration, says Texas will make up 35 percent of new utility-scale solar capacity in the U.S. this year, followed by California (10 percent) and Florida (6 percent).

While Texas’ solar efforts have shown positive trends, the state ranked No. 38 in a report by WalletHub that determined it was the thirteenth least green state.

ExxonMobil announces date to move legal headquarters to Texas

save the date

Energy giant Exxon Mobil Corp. has set a date to move its legal headquarters to Texas.

The Spring-based company announced this week that the redomiciliation from New Jersey to Texas is expected to be effective July 1. Exxon's board of directors unanimously recommended redomiciling in the Lone Star State in March, and shareholders approved the move to Texas at the company’s annual meeting in May.

As part of the move, ExxonMobil Holdings Corp. will replace Exxon Mobil Corp. of New Jersey and become the publicly traded parent company. Exxon reports that its shares will continue to trade on the New York Stock Exchange under the ticker symbol “XOM,” and that shareholders do not need to take action.

At the time of the recommendation, Exxon said the move would not affect business operations, management, strategy, assets or employee locations.

Exxon Chairman and CEO Darren Woods added that the redomiciliation was in part due to Texas' business-friendly environment and policies.

"Over the past several years, Texas has made a noticeable effort to embrace the business community. In doing so, it has created a policy and regulatory environment that can allow the company to maximize shareholder value,” Woods said in a news release. "Aligning our legal home with our operating home, in a state that understands our business and has a stake in the company’s success, is important.”

The Associated Press reports that about 30 percent of Exxon's employees work in Texas. Exxon's legal headquarters has been based in New Jersey since 1882, when it was Standard Oil Company.

Exxon moved its operational headquarters from Irving, Texas, to the Houston area in 2023.

Exxon was the highest-ranking Houston-area company on this year's Fortune 500 list, coming in at No. 9. Houston tied with Chicago for the second-most Fortune 500 headquarters on this year's list, with Texas leading the nation for the most Fortune 500 headquarters (57).

“Texas is the undisputed headquarters of headquarters,” Gov. Greg Abbott said in a news release. “The world’s leading businesses invest with confidence in Texas because of our welcoming business climate, predictable regulatory environment, and skilled and growing workforce. People and businesses are choosing Texas because Texas works.”

Houston startups named to World Economic Forum cohort for carbon removal, clean technologies

top honor

Two Houston-based startups have been selected to join the World Economic Forum's Technology Pioneers community.

The two-year program aims to help mission-driven, early-stage start-ups scale their innovations through multi-stakeholder initiatives, co-creating partnerships and other gatherings for community members. One-hundred startups are selected each year from around the globe, this year hailing from 23 countries and working in AI, energy, space, biotech markets and more.

Cleantech startup Vaulted Deep was one of 11 energy and climate companies to be named to the cohort. Julia Reichelstein and Omar Abou-Sayed founded the company in 2023. Its technology injects excess organic waste underground to remove carbon dioxide from the atmosphere.

Last year, Vaulted Deep inked a 12-year deal with Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.

The startup has earned several accolades in recent years, including a No. 3 spot on Fast Company’s list of the World’s Most Innovative Companies of 2026. It was also recently named to market intelligence and advisory firm Cleantech Group's annual Global Cleantech 100 list for a second year in a row.

"Waste management is one of the world's great invisible infrastructure systems ... The need for new infrastructure is growing as disposal challenges become more complex and regulations evolve. Vaulted is building the first new disposal pathway for organic waste in decades by putting it deep underground, permanently," the company shared in a LinkedIn post. "This year, we're joining the World Economic Forum's 2026 Tech Pioneers alongside innovators working on the many interconnected challenges shaping our future."

Houston-based Venus Aerospace was also selected to join the cohort, along with six other spacetech companies. The company was founded in 2020 by Sassie and Andrew Duggleby.

The startup specializes in next-generation rocket engine propulsion as a cleaner alternative to traditional combustion engines. The company's rotating detonation rocket engine (RDRE) burns fuel more efficiently and completed a successful high-thrust test flight last year. Venus says it’s the only company in the world that makes a flight-proven, high-thrust RDRE with a “clear path to scaled production.”

"Frontier technologies matter most when they expand what people, industries, and nations can do," Sassie Duggleby, co-founder and CEO of Venus, said in a news release. "For Venus, RDRE does not just represent a more efficient engine. It is a foundation for faster movement, more capable space systems, and new forms of connectivity across the planet. Being named a Technology Pioneer validates the potential of this technology to help shape a future where distance is less limiting."

Premium EV robotaxis from Uber will roll into Houston next year

Rolling On

More autonomous vehicles are expected to hit the roads in Houston next year.

Ridesharing giant Uber announced that it plans to roll out its premium robotaxi service in the Bayou City in mid-2027. Houston will be Uber’s second planned market for the program, following the San Francisco Bay Area, where the program is expected to be rolled out later this year.

Uber, Nuro and Lucid Group will bring the robotaxi program to Houston with more markets planned for the future. Currently, Nuro is conducting autonomous on-road testing with safety operators in Houston. Testing includes simulation, closed-course testing and supervised public-road testing.

“Houston is a city Nuro knows well, and we’re excited to help bring this robotaxi service to the city through our partnership with Uber and Lucid,” Andrew Chapin, chief operating officer at Nuro, said in a news release. “Houston’s large, complex metro area is an ideal market for demonstrating how Nuro’s universal autonomy platform can generalize across different geographies and operating environments. We look forward to continued engagement with the community as we prepare to launch service in 2027.”

The fleet of 100 vehicles across California and Texas will feature Lucid Gravity EVs and future Lucid Midsize vehicles equipped with Nuro Driver technology, Nuro’s Level 4 universal autonomy platform, plus a redundant sensor suite with cameras, lidar, radar and a roof-mounted halo.

The vehicles will be owned and operated by Uber and its fleet partners and made available to riders through the Uber network, according to the company.

In addition to the fleet of autonomous vehicles, Uber also announced that it has secured a 50,000-square-foot depot facility and dedicated charging pitstop in Houston. The facility will allow Uber and its partners to control vehicle maintenance, repairs, charging, cleaning, and day-to-day operations.

“Houston marks an important next step in our partnership with Lucid and Nuro as we expand autonomous mobility to more riders throughout the world,” Sarfraz Maredia, global head of autonomous mobility & delivery at Uber, added in the release. “Together, we’re combining best-in-class vehicle and autonomy technology with Uber’s scale, fleet operations expertise, and infrastructure capabilities to build a service that can grow across dozens of markets in the years ahead.”

Waymo launched its autonomous vehicle program in Houston in February.

The company later suspended its driverless car services in Houston, other major Texas cities, and Atlanta, after one of its vehicles was stranded by flooding during heavy rains. However, according to the Houston Chronicle, the fleet has resumed activity in Houston and is fully active.
