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The paper notes outdated recycling infrastructure and older technology as roadblocks.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

Houston-based ENGIE to add new wind and solar projects to Texas grid

coming soon

Houston-based ENGIE North America Inc. has expanded its partnership with Los Angeles-based Ares Infrastructure Opportunities to add 730 megawatts of renewable energy projects to the ERCOT grid.

The new projects will include one wind and two solar projects in Texas.

“The continued growth of our relationship with Ares reflects the strength of ENGIE’s portfolio of assets and our track record of delivering, operating and financing growth in the U.S. despite challenging circumstances,” Dave Carroll, CEO and Chief Renewables Officer of ENGIE North America, said in a news release. “The addition of another 730 MW of generation to our existing relationship reflects the commitment both ENGIE and Ares have to meeting growing demand for power in the U.S. and our willingness to invest in meeting those needs.”

ENGIE has more than 11 gigawatts of renewable energy projects in operation or under construction in the U.S. and Canada, and 52.7 gigawatts worldwide. The company is targeting 95 gigawatts by 2030.

ENGIE launched three new community solar farms in Illinois since December, including the 2.5-megawatt Harmony community solar farm in Lena and the Knox 2A and Knox 2B projects in Galesburg.

The company's 600-megawatt Swenson Ranch Solar project near Abilene, Texas, is expected to go online in 2027 and will provide power for Meta, the parent company of social media platform Facebook. Late last year, ENGIE also signed a nine-year renewable energy supply agreement with AstraZeneca to support the pharmaceutical company’s manufacturing operations from its 114-megawatt Tyson Nick Solar Project in Lamar County, Texas.

Houston geothermal company raises $97M Series B

fresh funding

Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.

Houston expert discusses the clean energy founder's paradox

Guest Column

Everyone tells you to move fast and break things. In clean energy, moving fast without structural integrity means breaking the only planet we’ve got. This is the founder's paradox: you are building a company in an industry where the stakes are existential, the timelines are glacial, and the capital requires patience.

The myth of the lone genius in a garage doesn’t really apply here. Clean energy startups aren’t just fighting competitors. They are fighting physics, policy, and decades of existing infrastructure. This isn’t an app. You’re building something physical that has to work in the real world. It has to be cheaper, more reliable, and clearly better than fossil fuels. Being “green” alone isn’t enough. Scale is what matters.

Your biggest risks aren’t competitors. They’re interconnection delays, permitting timelines, supply chain fragility, and whether your first customer is willing to underwrite something that hasn’t been done before.

That reality creates a brutal filter. Successful founders in this space need deep technical knowledge and the ability to execute. You need to understand engineering, navigate regulation, and think in terms of markets and risk. You’re not just selling a product. You’re selling a future where your solution becomes the obvious choice. That means connecting short-term financial returns with long-term system change.

The capital is there, but it’s smarter and more demanding. Investors today have PhDs in electrochemistry and grid dynamics. They’ve been burned by promises of miracle materials that never left the lab. They don't fund visions; they fund pathways to impact that can scale and make financial sense. Your roadmap must show not just a brilliant invention, but a clear, believable plan to drive costs down over time.

Capital in this sector isn’t impressed by ambition alone. It wants evidence that risk is being retired in the right order — even if that means slower growth early.

Here’s the upside. The difficulty of clean energy is also its strength. If you succeed, your advantage isn’t just in software or branding. It’s in hardware, supply chains, approvals, and years of hard work that others can’t easily copy. Your real competitors aren’t other startups. They’re inertia and the existing system. Winning here isn’t zero-sum. When one solution scales, it helps the entire market grow.

So, to the founder in the lab, or running field tests at a remote site: your pace will feel slow. The validation cycles are long. But you are building in the physical world. When you succeed, you don’t have an exit. You have a foundation. You don't just have customers; you have converts. And the product you ship doesn't just generate revenue; it creates a legacy.

If your timelines feel uncomfortable compared to software, that’s because you’re operating inside a system designed to resist change. And let’s not forget you are building actual physical products that interact with a complex world. Times are tough. Don’t give up. We need you.
