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."

Axiom Space taps solar array developer for first space station module

space contract

Houston-based Axiom Space is making progress on developing its commercial space station.

The company awarded Florida-based Redwire Corporation a contract to develop and deliver roll-out solar array (ROSA) wings to power the Axiom Payload Power Thermal Module (AxPPTM), which will be the first module for the new space station.

AxPPTM will initially attach to the International Space Station. AxPPTM will later separate from the ISS and rendezvous with Axiom’s Habitat 1 (AxH1) on orbit. Eventually, an airlock, Habitat 2 (AxH2) and finally the Research and Manufacturing Facility (AxRMF) will be added to the first two Axiom modules.

AxPPTM is anticipated to launch toward the end of 2027. The two-module station (AxPPTM and AxH1) is expected to be operational as a free-flying station by 2028, and the full four-module station around 2030.

The modules will be integrated and assembled at Axiom Space’s Assembly and Integration facility, making them the first human-rated spacecraft built in Houston.

Redwire’s ROSA technology was originally developed for the ISS, according to Space News. It has yielded a 100 percent success rate on on-orbit performance. The technology has also been used on NASA’s Double Asteroid Redirection Test mission, the Maxar-built Power and Propulsion Element for the Artemis Lunar Gateway and Thales Alenia Space’s Space Inspire satellites.

“As a market leader for space power solutions, Redwire is proud to be selected as a strategic supplier to deliver ROSAs for Axiom Space’s first space station module,” Mike Gold, Redwire president of civil and international space, said in a news release. “As NASA and industry take the next steps to build out commercial space stations to maintain U.S. leadership in low-Earth orbit, Redwire continues to be the partner of choice, enabling critical capabilities to ensure on-orbit success.”
