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."

Houston researchers develop breakthrough device that could bypass spinal injuries

breakthrough research

Scientists at Houston Methodist have announced a significant leap forward for spinal cord injury recovery.

The researchers have developed a device that essentially bypasses spinal injuries, allowing signals from previously “lost” functions to reach the brain, a new study published in Nature Communications shows.

“Most current technologies try to improve whatever function remains after a spinal cord injury,” Dr. Damiano Barone, assistant professor of neurosurgery in the Department of Neurosurgery at Houston Methodist and co-lead on the study, said in a news release. “Our goal is different. Rather than fixing the injury itself, we want to bypass it completely and create an alternative route for signals to travel.”

The study involved a single ultrathin circumferential electrode array made to conform around the spinal cord without penetrating neural tissue, which was implanted into rodent and pig models with spinal injuries. The electrode array was able to interpret motor, sensory and autonomic signals around the injury. Think of it as a set of detours that restore road access to isolated towns after a disaster destroys the highway instead of just rebuilding the highway.

Over the course of three days, the arrays detected signals of intended movement from low-frequency spinal oscillations with more than 94 percent accuracy. This worked across species and was replicated in feasibility studies on human cadavers.

This research could serve as a new foundation for neuroprosthetic implants that could restore connectivity to the 2.5 million people worldwide suffering from spinal injuries that result in loss of ability. Future development could result in everything from restored organ function to mobility, according to Houston Methodist.

George Malliaras, the Prince Professor of Technology in the Department of Engineering at the University of Cambridge, who co-led the study, sees it as a fundamental restructuring of the science of spinal trauma.

“This could represent a paradigm change in how we think about spinal cord injuries,” Malliaras said. “Instead of starting from the idea that what is lost is gone forever, this approach asks whether we can restore function by carrying the signal around the injury.”

Further work involving laboratory models will need to be completed before launching human trials.

Grants from the National Institutes of Health, Houston Methodist Katz Investigator Award, Helaers Research Award and the Engineering and Physical Sciences Research Council helped support the study. Other collaborators on the study include Salim Hadwe, Ruben Serrano, George Psaltakis, Margaux Forner, Chaeyeon Lee, Sydney Swedick, Moleca Ghnnam, Tawfique Hasan and Alejandro Carnicer-Lombarte from the University of Cambridge; and Anton Banta and Xueer Zhang from Houston Methodist.

Abbott assembles expert team to help lure U.S. Space Academy to Texas

space race

State Rep. Greg Bonnen of Friendswood has been tapped to lead a new team that will promote Texas as the future home of the U.S. Space Academy.

Bonnen, a neurosurgeon, chairs Houston Physicians’ Hospital and the powerful Texas House Appropriations Committee. His House district is close to NASA’s Johnson Space Center.

Gov. Greg Abbott appointed the seven-member team. Last month, President Trump signed an executive order establishing the Presidential Commission on the U.S. Space Academy. Commission members, who held their first meeting this month, will recommend a permanent location for the academy.

Texas officials are pushing a site near Johnson Space Center to host the academy. Alabama, Colorado and Florida are among Texas’ competitors.

In a joint statement, U.S. Sen. Ted Cruz and U.S. Rep. Brian Babin, both of Texas, issued a statement backing the state’s bid for the academy. Cruz lives in Houston. Babbin lives in Woodville, about 55 miles south of Beaumont.

“America’s space program is built across the country, but Texas is where the pieces come together,” the lawmakers said. “We are ready to lead the next generation of space pioneers and look forward to showing why Texas is the right home for the U.S. Space Academy.”

The academy’s curriculum will include technical education, leadership development and public service components. Graduates will be set up for careers in the U.S. military, civil service, and aerospace sectors.

The Abbott-appointed team will work with the Texas Space Commission to prepare the state’s proposal for the academy.

In addition to Bonnen, team members with ties to Houston include:

  • Robert Ambrose, who grew up in Houston. He worked at Johnson Space Center before becoming associate director of the Texas A&M Space Institute.
  • Former NASA astronaut Nancy Curry-Gregg, director of the Texas A&M Space Institute. She earned a doctoral degree from the University of Houston and previously worked at Johnson Space Center.
  • Former NASA astronaut Jack Fischer, senior vice president of Houston-based Intuitive Machines. The company builds spacecraft, delivers payloads to the moon and launches satellites.

“Texas is the home of America’s human spaceflight program,” Abbott said in a release. “No state can match what Texas brings to this mission.”

“NASA’s Johnson Space Center, world-class universities, a premier commercial space industry, major military installations, and an unmatched aerospace workforce give Texas every asset the United States Space Academy requires,” the governor added.
