The latest white paper from the University of Houston’s Energy Transition Institute analyzes how the U.S. currently handles plastics recycling and advocates for a national, policy-driven approach.

Ramanan Krishnamoorti, vice president for energy and innovation at UH; Debalina Sengupta, assistant vice president and chief operating officer at the Energy Transition Institute; and UH researcher Aparajita Datta authored the paper titled “Extended Producer Responsibility (EPR) for Plastics Packaging: Gaps, Challenges and Opportunities for Policies in the United States.” In the paper, the scientists argue that the current mix of state laws and limited recycling infrastructure are holding back progress at the national level.

EPR policies assign responsibility for the end-of-life management of plastic packaging to producers or companies, instead of taxpayers, to incentivize better product design and reduce waste.

“My hope is this research will inform government agencies on what policies could be implemented that would improve how we approach repurposing plastics in the U.S.,” Krishnamoorti said in a news release. “Not only will this information identify policies that help reduce waste, but they could also prove to be a boon to the circular economy as they can identify economically beneficial pathways to recycle materials.”

The paper notes outdated recycling infrastructure and older technology as roadblocks.

Currently, only seven states have passed EPR laws for plastic packaging. Ten others are looking to pass similar measures, but each looks different, according to UH. Additionally, each state also has its own reporting system, which leads to incompatible datasets. Developing national EPR policies or consistent nationwide standards could lead to cleaner and more efficient processes, the report says.

The researchers also believe that investing in sorting, processing facilities, workforce training and artificial intelligence could alleviate issues for businesses—and particularly small businesses, which often lack the resources to manage complex reporting systems. Digital infrastructure techniques and moving away from manual data collection could also help.

Public education on recycling would also be “imperative” to the success of new policies, the report adds.

“Experts repeatedly underscored that public education and awareness about EPR, including among policymakers, are dismal,” the report reads. “Infrastructural limitations, barriers to access and the prevailing belief that curbside recycling is ineffective in the U.S. contribute to public dissatisfaction, misinformation and, in some cases, opposition toward the use of taxpayers’ and ratepayers’ contributions for EPR.”

New UH white paper details Texas grid's shortfalls

grid warning

Two University of Houston researchers are issuing a warning about the Texas power grid: Its current infrastructure falls short of what’s needed to keep pace with rising demand for electricity.

The warning comes in a new whitepaper authored by Ramanan Krishnamoorti, vice president of energy and innovation at UH, and researcher Aparajita Datta, a Ph.D candidate at UH.

“As data centers pop up around the Lone Star State, electric vehicles become more commonplace, industries adopt decarbonization technologies, demographics change, and temperatures rise statewide, electricity needs in Texas could double by 2035,” a UH news release says. “If electrification continues to grow unconstrained, demand could even quadruple over the next decade.”

Without significant upgrades to power plants and supporting infrastructure, Texas could see electricity shortages, rising power costs and more stress on the state’s grid in coming years, the researchers say. The Electric Reliability Council of Texas (ERCOT) grid serves 90 percent of the state.

“Texas, like much of the nation, has fallen behind on infrastructure updates, and the state’s growing population, diversified economy and frequent severe weather events are increasing the strain on the grid,” Datta says. “Texas must improve its grid to ensure people in the state have access to reliable, affordable, and resilient energy systems so we can preserve and grow the quality of life in the state.”

The whitepaper’s authors caution that Texas faces a potential electricity shortfall of up to 40 gigawatts annually by 2035 if the grid doesn’t expand, with a more probable shortfall of about 27 gigawatts. And they allude to a repeat of the massive power outages in Texas during Winter Storm Uri in February 2021.

One gigawatt of electricity can power an estimated 750,000 homes in Texas, according to the Texas Solar + Storage Association.

The state’s current energy mix includes 40 percent natural gas, 29 percent wind, 12 percent coal, 10 percent nuclear and eight percent solar, the authors say.

Despite surging demand, 360 gigawatts of solar and battery storage projects are stuck in ERCOT’s queue, according to the researchers, and new natural gas plants have been delayed or withdrawn due to supply chain challenges, bureaucratic delays, policy uncertainties and shifting financial incentives.

Senate Bill 6, recently signed by Gov. Greg Abbott, calls for demand-response mandates, clearer rate structures and new load management requirements for big users of power like data centers and AI hubs.

“While these provisions are a step in the right direction,” says Datta, “Texas needs more responsive and prompt policy action to secure grid reliability, address the geographic mismatch between electricity demand and supply centers, and maintain the state’s global leadership in energy.”

Houston researchers: Texas to face gridlock challenges with reducing emissions in transportation

highway hiccup

A new report found that one of Texas' biggest roadblocks with reducing emissions is its transportation sector.

In its white paper series, the University of Houston's energy researchers found that — unless something changes — the Lone Star State is not likely to hit its carbon neutrality goals by 2050 within the transportation sector.

“What would it take to make the Texas transportation sector net zero by 2050?” Ramanan Krishnamoorti, UH vice president for energy and innovation, says in a news release. “The answer is a miracle, policy interventions that start as soon as possible, and somewhere between 30 to 50 billion dollars of public money between now and 2050 and at least an equal match from the private sector.”

According to the Net Zero in Texas: The Role of Transportation report, over 230 million metric tons of carbon dioxide gas is released from Texas roads each year. By 2050, estimates show that the remaining gasoline and diesel vehicles on the road will still be contributing about 40 million metric tons of emissions. Krishnamoorti collaborated with UH Energy researcher Aparajita Datta on a white paper.

“The future is crucial not only for Texas, where carbon emissions hinge on transportation solutions but also for our nation. Emissions transcend state lines and considering the size of Texas, its growing population and strong industry, the impact is significant,” Krishnamoorti adds.

Some of the challenges the state faces, per the report, hinge on electric vehicle adoption, which has been slow for a variety of reasons. One is the lack of EV production materials, such as lithium, cobalt, copper, manganese and graphite, due to increased demand, which is slated to be increased by 140 to 500 percent.

The EV workforce development also poses a challenge. Right now, hourly wages in the traditional auto sector range from $26 to $60, but most jobs in the EV industry, which are not unionized, range from $17 to $21 per hour.

The call for EV infrastructure is also estimated to be high. Per a news release about the report, "the change will require an annual expenditure of $250 million to $640 million for Level-2 (L2) charging stations and between $500 million and $1.3 billion for DC Fast Charging (DCFC) stations in 2040."

The transition will include an addition of 40,000 and 180,000 jobs in Texas between now and 2050, as well as an estimated $104 billion addition in public health benefits for Texans – fewer deaths, fewer asthma attacks and fewer sick days, according to the study.

“It is evident that decarbonizing Texas’ transportation sector will be a significant challenge and relying solely on consumer behavior to change is unrealistic,” Krishnamoorti says in the release. “We need robust policies to drive the state’s transportation electrification. Let’s acknowledge the journey ahead; federal mandates alone will not guide us to net zero by 2050. Texas needs to act now.”

Spring-based private equity firm acquires West Texas wind farm

power deal

Spring-based private equity firm Arroyo Investors has teamed up with ONCEnergy, a Portland, Oregon-based developer of clean energy projects, to buy a 60-megawatt wind farm southeast of Amarillo.

Skyline Renewables, which acquired the site, known as the Whirlwind Energy Center, in 2018, was the seller. The purchase price wasn’t disclosed.

Whirlwind Energy Center, located in Floyd County, West Texas, comprises 26 utility-scale wind turbines. The wind farm, built in 2007, supplies power to Austin Energy.

“The acquisition reflects our focus on value-driven investments with strong counterparties, a solid operating track record, and clear relevance to markets with growing capacity needs,” Brandon Wax, a partner at Arroyo, said in a press release. “Partnering with ONCEnergy allows us to leverage deep operational expertise while expanding our investment footprint in the market.”

Arroyo focuses on energy infrastructure investments in the Americas. Its portfolio includes Spring-based Seaside LNG, which produces liquefied natural gas and LNG transportation services.

Last year, Arroyo closed an investment fund with more than $1 billion in total equity commitments.

Since its launch in 2003, Arroyo has “remained committed to investing in high-quality assets, creating value and positioning assets for exit within our expected hold period,” founding partner Chuck Jordan said in 2022.

$524M Texas Hill Country solar project powered by Hyundai kicks off

powering up

Corporate partners—including Hyundai Engineering & Construction, which maintains a Houston office—kicked off a $524 million solar power project in the Texas Hill Country on Jan. 27.

The 350-megawatt, utility-scale Lucy Solar Project is scheduled to go online in mid-2027 and represents one of the largest South Korean-led investments in U.S. renewable energy.

The solar farm, located on nearly 2,900 acres of ranchland in Concho County, will generate 926 gigawatt-hours of solar power each year. That’s enough solar power to supply electricity to roughly 65,000 homes in Texas.

Power to be produced by the hundreds of thousands of the project’s solar panels has already been sold through long-term deals to buyers such as Starbucks, Workday and Plano-based Toyota Motor North America.

The project is Hyundai Engineering & Construction’s largest solar power initiative outside Asia.

“The project is significant because it’s the first time Hyundai E&C has moved beyond its traditional focus on overseas government contracts to solidify its position in the global project financing market,” the company, which is supplying solar modules for the project, says on its website.

Aside from Hyundai Engineering & Construction, a subsidiary of automaker Hyundai, Korean and U.S. partners in the solar project include Korea Midland Power, the Korea Overseas Infrastructure & Urban Development Corp., solar panel manufacturer Topsun, investment firm EIP Asset Management, Primoris Renewable Energy and High Road Energy Marketing.

Primoris Renewable Energy is an Aurora, Colorado-based subsidiary of Dallas-based Primoris Services Corp. Another subsidiary, Primoris Energy Services, is based in Houston.

High Road is based in the Austin suburb of West Lake Hills.

“The Lucy Solar Project shows how international collaboration can deliver local economic development and clean power for Texas communities and businesses,” says a press release from the project’s partners.

Elon Musk vows to put data centers in space and run them on solar power

Outer Space

Elon Musk vowed this week to upend another industry just as he did with cars and rockets — and once again he's taking on long odds.

The world's richest man said he wants to put as many as a million satellites into orbit to form vast, solar-powered data centers in space — a move to allow expanded use of artificial intelligence and chatbots without triggering blackouts and sending utility bills soaring.

To finance that effort, Musk combined SpaceX with his AI business on Monday, February 2, and plans a big initial public offering of the combined company.

“Space-based AI is obviously the only way to scale,” Musk wrote on SpaceX’s website, adding about his solar ambitions, “It’s always sunny in space!”

But scientists and industry experts say even Musk — who outsmarted Detroit to turn Tesla into the world’s most valuable automaker — faces formidable technical, financial and environmental obstacles.

Feeling the heat

Capturing the sun’s energy from space to run chatbots and other AI tools would ease pressure on power grids and cut demand for sprawling computing warehouses that are consuming farms and forests and vast amounts of water to cool.

But space presents its own set of problems.

Data centers generate enormous heat. Space seems to offer a solution because it is cold. But it is also a vacuum, trapping heat inside objects in the same way that a Thermos keeps coffee hot using double walls with no air between them.

“An uncooled computer chip in space would overheat and melt much faster than one on Earth,” said Josep Jornet, a computer and electrical engineering professor at Northeastern University.

One fix is to build giant radiator panels that glow in infrared light to push the heat “out into the dark void,” says Jornet, noting that the technology has worked on a small scale, including on the International Space Station. But for Musk's data centers, he says, it would require an array of “massive, fragile structures that have never been built before.”

Floating debris

Then there is space junk.

A single malfunctioning satellite breaking down or losing orbit could trigger a cascade of collisions, potentially disrupting emergency communications, weather forecasting and other services.

Musk noted in a recent regulatory filing that he has had only one “low-velocity debris generating event" in seven years running Starlink, his satellite communications network. Starlink has operated about 10,000 satellites — but that's a fraction of the million or so he now plans to put in space.

“We could reach a tipping point where the chance of collision is going to be too great," said University at Buffalo's John Crassidis, a former NASA engineer. “And these objects are going fast -- 17,500 miles per hour. There could be very violent collisions."

No repair crews

Even without collisions, satellites fail, chips degrade, parts break.

Special GPU graphics chips used by AI companies, for instance, can become damaged and need to be replaced.

“On Earth, what you would do is send someone down to the data center," said Baiju Bhatt, CEO of Aetherflux, a space-based solar energy company. "You replace the server, you replace the GPU, you’d do some surgery on that thing and you’d slide it back in.”

But no such repair crew exists in orbit, and those GPUs in space could get damaged due to their exposure to high-energy particles from the sun.

Bhatt says one workaround is to overprovision the satellite with extra chips to replace the ones that fail. But that’s an expensive proposition given they are likely to cost tens of thousands of dollars each, and current Starlink satellites only have a lifespan of about five years.

Competition — and leverage

Musk is not alone trying to solve these problems.

A company in Redmond, Washington, called Starcloud, launched a satellite in November carrying a single Nvidia-made AI computer chip to test out how it would fare in space. Google is exploring orbital data centers in a venture it calls Project Suncatcher. And Jeff Bezos’ Blue Origin announced plans in January for a constellation of more than 5,000 satellites to start launching late next year, though its focus has been more on communications than AI.

Still, Musk has an edge: He's got rockets.

Starcloud had to use one of his Falcon rockets to put its chip in space last year. Aetherflux plans to send a set of chips it calls a Galactic Brain to space on a SpaceX rocket later this year. And Google may also need to turn to Musk to get its first two planned prototype satellites off the ground by early next year.

Pierre Lionnet, a research director at the trade association Eurospace, says Musk routinely charges rivals far more than he charges himself —- as much as $20,000 per kilo of payload versus $2,000 internally.

He said Musk’s announcements this week signal that he plans to use that advantage to win this new space race.

“When he says we are going to put these data centers in space, it’s a way of telling the others we will keep these low launch costs for myself,” said Lionnet. “It’s a kind of powerplay.”
