VoltaGrid, a Bellaire-based startup that specializes in distributed power generation via microgrids, has hauled in $150 million in equity funding.

Founded in 2020, VoltaGrid provides small-scale, self-contained microgrids that can operate independently of major power grids or in tandem with other microgrids. VoltaGrid’s product consists of natural gas engines, portable energy storage, natural gas processing and grid power connectivity.

Investors in the $150 million round include the Canada Pension Plan Investment Board (CPP Investments), Longbow Capital, Walter Ventures, and Pilot Company (operator of more than 800 retail and fueling locations in the U.S. and Canada). The $150 million round comes less than a year after VoltaGrid announced a $100 million round featuring the same investors.

VoltaGrid says it will spend the fresh cash to grow its power generation portfolio, along with its low-carbon fuel program in partnership with Pilot. The low-carbon platform features hydrogen and compressed natural gas.

“VoltaGrid continues to set new milestones across multiple sectors and business lines as we execute on our proven strategy with key partners,” Nathan Ough, president and CEO of VoltaGrid, says in a news release.

“Our strategy to establish one of the largest asset bases of portable generation, uniquely paired with our low-carbon fueling solutions, has significantly decreased the complexity for our partners to electrify their operations. I am thankful to our team members for the tremendous amount of work that has been contributed to create one of the largest portfolios of contracted low carbon fuels in the industry.”

Houston founders aim to provide equity through energy resiliency

Houston innovators podcast episode 143

As temperatures climb and devastating natural disasters continue to test the power grid, two Houston innovators have a solution: Smart microgrids.

"Microgrids have been around for a very long time," Paresh Patel, co-founder of InnoGrid, says on the Houston Innovators Podcast. "We're primed here in Houston and in Texas to really see microgrids go mainstream. ... People want to see that they have control and are in charge of their own power."

Patel co-founded InnoGrid with Ed Pettitt and a few other collaborators following the 2020 Houston Climathon. The social enterprise is working to establish community microgrids in lower income areas — neighborhoods that are most at risk of devastating power outages.

"We want to convert the commercial microgrid model for low and moderate income and undresourced residential communities," Patel explains.

And there's never been a better time to shine a spotlight on microgrids as a solution to unreliable power systems, Pettitt says.

"We're dealing with massive inflation — costs are going up especially in food and energy," he explains on the show. "Even prior to this time of inflation, electricity prices in the US were expected to increase across the board. Hundreds of thousands of people right now today are being pushed below the poverty line because of increased energy costs. We need to be more creative in how we upgrade our infrastructure."

And the current grid system is well overdue for an upgrade. The microgrid system fits right in with the shared economy we live in today, Patel says, and it allows for more generation of energy that is decentralized, digitalized, decarbonized, and democratized — the four Ds as he says.

"When you consider our current grid system, it is a vestige of the industrial revolution — it's 140 years old. That business model is ripe for innovation," Patel says.

"We need to accelerate deployment of microgrid models," he continues. "I don't think we can afford to update our current grid system — it'll cost $2 trillion."

Most importantly, these microgrids need to be implemented in an equitable way, the founders say, and InnoGrid has its eyes on one Houston area in particular. The Innovation Corridor, which spans from the Texas Medical Center to Downtown Houston, would be the ideal region to deploy the technology.

"If you look at the innovation corridor, it forms the spine of the city. You have so many important municipal buildings, first-responding organizations, and a large amount of affordable housing in the area. There's critical resources here that we want to make sure the lights stay on in power disasters," Pettit says. "One of the things we believe at InnoGrid is that where you live shouldn't determine whether or not you survive a national weather event. We want to make sure we provide energy stability in the communities that need it most."

To make this dream into a reality, InnoGrid needs the right partnerships and support in the area — and the founders have made progress. InnoGrid recently participated in the Ion Smart and Resilient Cities Accelerator and has a relationship with Greentown Houston across the street.

Eventually, as Pettit says, InnoGrid wants to help lead Houston to becoming a hub for microgrid innovation.

"We're looking at other cities — like Chicago and Boston — and how they've deployed their microgrids and making sure we're bringing those best practices in Houston," Pettit says. "Eventually we want to be the leader in developing these microgrid best practices as the energy capital of the world."

Aegis Aerospace appoints Houston space leader as new president

moving up

Houston-based Aegis Aerospace's current chief strategy officer, Matt Ondler, will take on the additional role of president on Jan. 1. Ondler will succeed Bill Hollister, who is retiring.

“Matt's vision, experience, and understanding of our evolving markets position us to build on our foundation and pursue new frontiers,” Stephanie Murphy, CEO of Aegis Aerospace, said in a news release.

Hollister guided Aegis Aerospace through expansion and innovation in his three years as president, and will continue to serve in the role of chief technology officer (CTO) for six months and focus on the company's technical and intellectual property frameworks.

"Bill has played an instrumental role in shaping the success and growth of our company, and his contributions leave an indelible mark on both our culture and our achievements," Murphy said in a news release.

Ondler has a background in space hardware development and strategic leadership in government and commercial sectors. Ondler founded subsea robots and software company Houston Mechatronics, Inc., now known as Nauticus Robotics, and also served as president, CTO and CSO during a five-year tenure at Axiom Space. He held various roles in his 25 years at NASA and was also named to the Texas Aerospace Research and Space Economy Consortium Executive Committee last year.

"I am confident that with Matt at the helm as president and Bill supporting us as CTO, we will continue to build on our strong foundation and further elevate our impact in the space industry," Murphy said in a news release. "Matt's vision, experience, and understanding of our evolving markets position us to build on our foundation and pursue new frontiers."

Rice University launches new center to study roots of Alzheimer’s and Parkinson’s

neuro research

Rice University launched its new Amyloid Mechanism and Disease Center last month, which aims to uncover the molecular origins of Alzheimer’s, Parkinson’s and other amyloid-related diseases.

The center will bring together Rice faculty in chemistry, biophysics, cell biology and biochemistry to study how protein aggregates called amyloids form, spread and harm brain cells. It will serve as the neuroscience branch of the Rice Brain Institute, which was also recently established.

The team will work to ultimately increase its understanding of amyloid processes and will collaborate with the Texas Medical Center to turn lab discoveries into real progress for patients. It will hold its launch event on Jan. 21, 2026, and hopes to eventually be a launchpad for future external research funding.

The new hub will be led by Pernilla Wittung-Stafshed, a Rice biophysicist and the Charles W. Duncan Jr.-Welch Chair in Chemistry.

“To make a real difference, we have to go all the way and find a cure,” Wittung-Stafshede said in a news release. “At Rice, with the Amyloid Mechanism and Disease Center as a catalyst, we have the people and ideas to open new doors toward solutions.”

Wittung-Stafshede, who was recruited to Rice through a Cancer Prevention and Research Institute of Texas grant this summer, has led pioneering work on how metal-binding proteins impact neurodegenerative disorders, including Alzheimer’s and Parkinson’s diseases. Her most recent study, published in Advanced Science, suggests a new way of understanding how amyloids may harm cells and consume the brain’s energy molecule, ATP.

According to Alzheimer’s Disease International, neurodegenerative disease cases could reach around 78 million by 2030 and 139 million by 2050. Wittung-Stafshede’s father died of dementia several years ago.

“This is close to my heart,” Wittung-Stafshede added in the news release. “Neurodegenerative diseases such as dementia, Alzheimer’s and Parkinson’s are on the rise as people live longer, and age is the largest risk factor. It affects everyone.”

This Houston airport saw sharp passenger decline in 2025, study shows

Travel Talk

A new global airport travel study has revealed passenger traffic at Houston's William P. Hobby Airport (HOU) sharply decreased from 2024 to 2025.

The analysis from travel magazine LocalsInsider examined recently released data from the Bureau of Transportation Statistics (BTS), the U.S. International Trade Association, and a nationwide survey to determine the following American traveler habits: The most popular U.S. and international destinations, emerging hotspots, and destinations on the decline. The study covered passenger travel trends from January through July 2025.

In the report's ranking of the 40 U.S. airports with the sharpest declines in passenger traffic, HOU ranked 13th on the list.

About 4.26 million arrivals were reported at HOU from January through July 2024, compared to about 3.96 million during the same seven-month period in 2025. According to the data, that's a significant 7.1 percent drop in passenger traffic year-over-year, or a loss of 300,974 passengers.

"As travelers chase new hotspots, some destinations are seeing reduced passenger traffic whether due to rising costs, shifting airline schedules, or evolving traveler preferences, some destinations are seeing a decrease in visitors," the report's author wrote.

It appears most major Texas airports had drops in passenger traffic from 2024 to 2025. Dallas Love Field Airport (DAL) saw the worst in the state, with a dramatic 7.4 percent dip in arrivals. DAL also ranked 11th on the list of U.S. airports with the steepest declines in passenger traffic.

More than 5.13 million arrivals were reported at DAL from January through July 2024, compared to over 4.75 million during the same seven-month period in 2025.

This is how passenger traffic has fallen at other major Texas airports from 2024 to 2025:

Austin-Bergstrom International Airport (AUS):

  • 6,107,597 – Passenger arrivals from January to July 2024
  • 5,828,396 – Passenger arrivals from January to July 2025
  • -4.6 percent – Year-over-year passenger change
