Yet another reason to loathe plastic bags

Guest column

As waste-to-energy gains a foothold in the energy transition, trash's more palatable cousin, recycling, sits just close enough for deeper inspection. Plastic, by and large, one of the most loved and loathed petroleum by-products, is often singled out as the most nefarious contributor to our declining climate.

With significant efforts underway to reduce the volume of single-use plastic while reusing or repurposing stronger plastics, let us turn attention to the third action in the timeless mantra–recycling.

Over the last few decades, we have embraced recycling globally, assured in our noble commitment to derive further utility out of items that no longer serve an immediate purpose from our unique perspective.

However, the act of recycling still closely resembles taking out the trash. We place items deemed worthy of secondary use into large, usually plastic, bins for carting far away from the rest of the things that still provide utility to our personal household or place of business.

For the most part, simply believing that there could or should be further utility of an item is criterion enough to warrant placement in the exalted blue bin. The small hit of dopamine elicited from the satisfaction that we are “doing our part” is just strong enough to reinforce the idea that we have also “done enough.”

But according to Vu Nguyen, director of corporate development and innovation, Waste Management, one of Houston’s leading trash, recycling, and environmental services companies, there remains one elusive challenge: the plastic bag.

The plastic bag proves problematic for a multitude of reasons, not least because of its role in ruining literally every.other.recyling.effort.ever. On the whole, we have been blissfully ignorant of the recycling process, and even more so of how much our good intentions to reuse and recycle are thwarting the same process for so many other reusable materials.

“The number one thing that consumers can remember when it comes to recycling is that thin, pliable plastic [like] bags and wrappers should be firmly excluded from standard blue recycling bins,” Nguyen shared at a Houston Tech Rodeo event earlier this spring.

After collection, simple but effective mechanisms sort items delivered to a recycling facility. Individuals pick through discarded materials placed on conveyor belts before the remaining items work their way through heavy magnets that extract useful metals while bursts of air pressure push lightweight items like paper away from heavier items like glass.

Plastic bags, including the lovely little blue ones so many of us like to purchase to fill our quaint non-standard recycling bins, tangle up in these conveyor belts, causing shutdowns to unravel them from materials otherwise well-suited for these sorting efforts. Downtime on the sorting line can get expensive, so much so that many recycling facilities often turn away entire trucks filled with potentially reusable items if even a single plastic bag is discovered inside.

Consider this the start of a public service announcement campaign to raise awareness of that simple fact.

Yasser Brenes, area president – south for Republic Services, echoes this sentiment as he shares a few tips and reminders with EnergyCapitalHTX.

  • Know What to Throw: Educate yourself on what can and cannot go inside your recycling bin. Focus on only recycling rigid plastic containers such as bottles, jugs and tubs, metal food and beverage containers, glass bottles and jars, paper and cardboard. Don’t be a wish-cycler, never throw items in your recycling bin if you are unsure if they can be recycled or not.
  • Empty, Clean, Dry: Recyclables should be rinsed free of residual food and liquid. If recyclables are not empty, clean and dry the residual food or liquid could contaminate other more fragile recyclables, like paper and cardboard, and require them to be thrown away.
  • Don’t Bag It: Recyclables should always be placed loose inside your recycling bin. Flexible plastics, such as grocery bags, wrap and tangle around the sorting equipment and should never be placed in your recycling bin.

That’s not to say that plastic bags and wrappers cannot be recycled at all; on the contrary, they absolutely can. The mechanisms for sorting them from other materials like paper, aluminum, glass, and heavy plastics just aren’t quite mature enough… yet.

How Mitsubishi Heavy Industries America is advancing the hydrogen economy

The View from HETI

Mitsubishi Heavy Industries America (MHIA), a steering-level member company of the Houston Energy Transition Initiative, is leveraging engineering expertise and global capabilities to develop and deploy technologies that will decarbonize existing infrastructure and build the hydrogen economy of the future. The company’s recent investment in Koloma, a Colorado-based geologic hydrogen exploration startup, demonstrates its commitment to breakthrough innovations that can transform how the world produces and uses clean energy.

Traditional hydrogen production methods, whether from natural gas with carbon capture or from electrolysis using renewable electricity, require significant energy inputs and infrastructure investments. Geologic hydrogen represents a potentially transformative alternative: naturally occurring hydrogen deposits that can be extracted from underground reservoirs.

Koloma is pioneering the exploration and commercialization of geologic hydrogen using proprietary technology, unique data sets, and specialized expertise to identify and develop these resources globally. If successful at scale, geologic hydrogen could provide clean, affordable hydrogen without the energy penalty of production.

MHIA’s investment in Koloma joins a syndicate of strategic partners committed to accelerating hydrogen development:

  • Breakthrough Energy Ventures: Bill Gates’ climate investment fund focused on breakthrough technologies
  • Amazon’s Climate Pledge Fund: Supporting technologies that enable Amazon’s path to net zero
  • United Airlines’ Sustainable Flight Fund: Investing in solutions for aviation decarbonization

This partnership brings together technology innovation, capital, and potential customers to create the ecosystem needed to move from exploration to commercial deployment.

MHIA’s investment in geologic hydrogen is part of the company’s broader strategy to develop the complete hydrogen value chain:

Production: Beyond geologic hydrogen, MHIA is advancing technologies for hydrogen production from diverse sources, including natural gas with carbon capture and renewable-powered electrolysis.

Infrastructure: The company is developing the compression, storage, and transportation systems needed to move hydrogen from production sites to end users.

End-Use Applications: MHIA’s expertise spans power generation, industrial processes, and transportation applications that can utilize hydrogen as a clean fuel.

Integration: The company is working to integrate hydrogen systems with existing infrastructure, enabling decarbonization without requiring complete infrastructure replacement.

While new technologies like geologic hydrogen offer exciting possibilities, MHIA recognizes that much of the world’s energy infrastructure will continue operating for decades. The company is also investing in technologies that decarbonize existing systems:

  • MHIA is developing and deploying carbon capture systems that can be retrofitted to existing power plants and industrial facilities, allowing them to continue operating while dramatically reducing emissions.
  • The company’s gas turbine technologies can operate on blends of natural gas and hydrogen, enabling progressive decarbonization as hydrogen availability increases.
  • Through advanced controls, materials, and designs, MHIA is improving the efficiency of existing infrastructure—reducing fuel consumption and emissions without requiring replacement.

MHIA’s approach to the energy transition is guided by a clear mission: develop innovative technologies that help achieve a decarbonized society while maintaining energy security and affordability. This mission recognizes several important realities:

Energy Access Matters: Billions of people still lack access to reliable, affordable energy. Solutions must scale globally and work across diverse economic contexts.

Existing Infrastructure Represents Enormous Investment: The world has trillions of dollars invested in energy infrastructure. Solutions that work with this infrastructure can deploy faster than those requiring complete replacement.

Multiple Pathways Are Needed: No single technology will solve the climate challenge. Success requires parallel development of multiple solutions—hydrogen, carbon capture, renewables, nuclear, efficiency, and others.

Speed Matters: Climate change is a time-sensitive challenge. Technologies that can deploy at scale in the 2020s and 2030s matter more than perfect solutions that might be available in the 2040s or 2050s.

From Technology to Impact

MHIA’s investment in Koloma reflects the company’s belief that breakthrough technologies require patient capital, technical expertise, and strategic partnerships to move from concept to commercial reality. Geologic hydrogen has the potential to provide clean, affordable hydrogen at scale—but only if exploration techniques are validated, production methods are proven, and commercial models are demonstrated.

By investing early and providing both capital and technical support, MHIA is helping to accelerate this timeline. If Koloma succeeds, the impact could extend far beyond a single project and could unlock a vast new resource for the global energy transition.

The energy transition requires engineering excellence, patient capital, and willingness to back breakthrough innovations before they’re fully proven. Through HETI member companies like Mitsubishi Heavy Industries America, Houston is demonstrating the leadership, technical capabilities, and strategic vision needed to build a hydrogen economy that can help decarbonize the world’s energy system.

Energy expert: Houston welcomed the world — can Texas power what's next?

guest column

For a few weeks this summer, Houston welcomed the world.

The FIFA World Cup 2026 showcased our city's ability to host one of the largest international events on the planet. Millions watched from around the globe while hundreds of thousands of visitors experienced firsthand what Houston has become: a world-class destination for business, culture and global events.

But once the final match is played and the visitors return home, a more important question remains: Can Texas build the energy infrastructure needed to power what comes next?

The World Cup wasn't the finish line. It was a glimpse into the future.

That future is being shaped not only by population growth, but also by artificial intelligence, hyperscale data centers, advanced manufacturing, electrification, LNG expansion and continued industrial investment. Together, these forces are creating an unprecedented demand for electricity and placing new expectations on the infrastructure that supports it.

Energy Has Become Economic Infrastructure

For decades, economic development centered around highways, ports, airports and workforce.

Today, another asset has moved to the top of that list: energy infrastructure.

Reliable electricity is no longer simply a utility service. It has become a competitive advantage.

Companies evaluating where to build the next AI campus, manufacturing facility or industrial complex are increasingly asking different questions. How quickly can power be delivered? Is there enough transmission capacity? Can substations support future expansion? Is water infrastructure available? What is the long-term reliability of the local grid?

These questions are becoming just as important as tax incentives and available real estate.

Recent comments from Governor Greg Abbott that future AI developments should provide their own power generation and water illustrate just how dramatically the conversation has evolved. The challenge is no longer limited to meeting today's demand. It is preparing for a future where entirely new industries require unprecedented amounts of electricity while ensuring existing homes and businesses continue to receive reliable, affordable service.

The Next Energy Race Has Already Begun

Texas remains the nation's energy leader, producing more electricity than any other state while continuing to expand natural gas, wind, solar and emerging technologies.

But leadership in the next decade will be measured differently.

Success will depend on how quickly we can expand transmission infrastructure, modernize distribution systems, accelerate interconnection, strengthen grid resilience and support new generation where economic growth is occurring.

The conversation has shifted from producing more electricity to delivering it smarter.

That requires planning years before demand arrives.

Houston Is the Proving Ground

Houston sits at the center of this transformation.

Already recognized as the Energy Capital of the World, the region continues attracting major employers, global headquarters, industrial expansion and technology investment. The Port of Houston continues to grow. Advanced manufacturing is expanding. AI companies are evaluating Texas alongside other national markets.

Every one of these investments depends on reliable infrastructure.

While the World Cup demonstrated Houston's ability to manage a temporary surge of visitors, the more significant challenge lies ahead. Permanent economic growth creates sustained electricity demand that cannot be addressed with temporary solutions.

Meeting that demand will require coordinated investment across generation, transmission, distribution, storage and increasingly, digital technologies capable of forecasting and managing electricity in real time.

Smarter Infrastructure for a Smarter Grid

The future electric grid will look very different from the one that built modern Texas.

Artificial intelligence, predictive analytics, advanced sensors and distributed energy resources will allow operators to anticipate demand, identify equipment failures before they occur and optimize energy delivery across increasingly complex networks.

Infrastructure is no longer simply about building more. It is about building smarter.

At the same time, resilience must remain central to every investment. Texans understand better than most that hurricanes, flooding, winter storms and prolonged heat waves are no longer rare events. Modern infrastructure must not only support growth but also withstand increasingly volatile weather.

Building Beyond the Headlines

The World Cup generated headlines because of what happened on the field.

Its lasting legacy may be what it revealed about the city beyond the stadium.

Houston demonstrated that it can host the world. The next challenge is ensuring it can continue to power one of the fastest-growing economies in North America.

That will require continued investment, thoughtful policy and long-term planning that recognizes energy infrastructure as essential economic infrastructure.

Texas has spent decades leading the world in energy production.

The next opportunity is even greater.

To become the global leader in how energy systems are planned, built and operated for a future defined by artificial intelligence, industrial growth and rapidly evolving consumer demand.

Because the cities that lead tomorrow won't simply generate the most energy.

They'll be the ones best prepared to deliver it where opportunity is growing.
