Texas-based energy startup raises $1 billion on heels of Houston expansion

Powering Up

Austin-based startup Base Power, which offers battery-supported energy in the Houston area and other regions, has raised $1 billion in series C funding—making it one of the largest venture capital deals this year in the U.S.

VC firm Addition led the $1 billion round. All of Base Power’s existing major investors also participated, including Trust Ventures, Valor Equity Partners, Thrive Capital, Lightspeed Venture Partners, Andreessen Horowitz (a16z), Altimeter, StepStone Group, 137 Ventures, Terrain, Waybury Capital, and entrepreneur Elad Gil. New investors include Ribbit Capital, Google-backed CapitalG, Spark Capital, Bond, Lowercarbon Capital, Avenir Growth Capital, Glade Brook Capital Partners, Positive Sum and 1789 Capital Management.

Coupled with the new $1 billion round, Base Power has hauled in more than $1.27 billion in funding since it was founded in 2023.

Base Power supplies power to homeowners and the electric grid through a distributed storage network.

“The chance to reinvent our power system comes once in a generation,” Zach Dell, co-founder and CEO of Base Power, said in a news release. “The challenge ahead requires the best engineers and operators to solve it, and we’re scaling the team to make our abundant energy future a reality.”

Zach Dell is the son of Austin billionaire and Houston native Michael Dell, chairman and CEO of Round Rock-based Dell Technologies.

In less than two years, Base Power has developed more than 100 megawatt-hours of battery-enabled storage capacity. One megawatt-hour represents one hour of energy use at a rate of one million watts.

Base Power recently expanded its service to the city of Houston. It already was delivering energy to several other communities in the Houston area. To serve the Houston region, the startup has opened an office in Katy.

The startup also serves the Dallas-Fort Worth and Austin markets. At some point, Base Power plans to launch a nationwide expansion.

To meet current and future demand, Base Power is building its first energy storage and power electronics factory at the former downtown Austin site of the Austin American-Statesman’s printing presses.

“We’re building domestic manufacturing capacity for fixing the grid,” Justin Lopas, co-founder and chief operating officer of Base Power, added in the release. “The only way to add capacity to the grid is [by] physically deploying hardware, and we need to make that here in the U.S. ... This factory in Austin is our first, and we’re already planning for our second.”

Houston professor awarded $2.6M grant for retina, neurological research

seeing green

University of Houston College of Optometry Professor John O’Brien has received a $2.6 million grant from the National Eye Institute to continue his research on the retina and neurological functions.

O’Brien is considered a leading expert in retinal neuroscience with more than 20 years of research in the field. The new funding will allow O’Brien and his team to continue to study the dense assembly of proteins associated with electrical synapses, or gap junctions, in the retina.

Gap junctions transfer electrical signals between neurons. And the plasticity of gap junctions changes the strength of a synapse, in turn changing how visual information is processed. Previous research has shown that reduced functions of electrical synapses could be linked to autism, while their hyperfunction may lead to seizures.

“The research we propose will significantly advance our understanding of the molecular complexes that control the function of electrical synapses,” O’Brien said in a news release.

The team at UH will work to identify the proteins and examine how they impact electrical synapses. It is particularly interested in the Connexin 36, or Cx36, protein. According to O’Brien, phosphorylation of Cx36, a short-term chemical modification of the protein, serves as a key driver of plasticity. And the protein has been linked to refractive error development, which is one of the largest vision problems in the world today.

Additionally, OBrien’s research has shown that plasticity is essential for all-day vision, allowing the retina to adjust sensitivity and sharpen images. He has also built a catalog of the core set of proteins surrounding electrical synapses that are conserved across species. His research has been funded by the NEI since 2000.

Capwell Services

Houston-based methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the US and Canada, equivalent to more than 400 million metric tons of CO2e per year. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by current CEO Andrew Lane. It has since participated in programs with Greentown Labs and Rice Clean Energy Accelerator. The company moved to Houston in 2023 and raised a pre-seed round. It has also received federal funding from the DOE. Capwell is currently piloting its commercial unit with oil and gas operators.

Deep Anchor Solutions

Offshore energy consulting and design company Deep Anchor Solutions aims to help expedite the adoption of floating offshore energy infrastructure with its deeply embedded ring anchor (DERA) technology. According to the company, its patented DERA system can be installed quietly without heavy-lift vessels, reducing anchor-related costs by up to 75 percent and lifecycle CO2 emissions by up to 80 percent.

The company was founded in 2023 by current CEO Junho Lee and CTO Charles Aubeny. Lee earned his Ph.D. in geotechnical engineering from Texas A&M University, where Aubeny is a professor of civil and environmental engineering. The company has not raised VC funding, but has participated in numerous accelerators and incubators, including Greentown Labs, MassChallenge, EnergyTechNexus LiftOff and others. Lee is an Activate 2025 fellow.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers and rubbers. The company reports that it plans to open its first commercial plant in the next 18 months.
