For the third year, Greentown Labs and Browning the Green Space have opened applications for ACCEL, a climatetech accelerator designed to bolster BIPOC-led companies.

The program, which is a year-long commitment providing opportunities across funding, networking connections, resources, and more, has applications open until January 7. Each selected company will receive non-dilutive grant funding up to $25,000, trainings from VentureWell, a desk and membership at Greentown Houston or Boston locations, a BGS membership, and more.

A handful of startups will be selected for the program, which is looking for companies at the two to four Technology Readiness Level (TRL ) stage with a technology solution across agriculture, buildings, electricity, manufacturing, resiliency and adaptation, and transportation sectors.

“ACCEL has been amazing," Chidalu Onyenso, founder of Cambridge, Massachusetts-based EarthBond, a member of the 2022 cohort, writes on the website. "I’ve really enjoyed the membership and programming. I think it’s fantastic—if I met another Black or Brown founder focused on climatetech, I’d tell them to apply to this program, 100 percent.”

Earlier this year, the program — which is supported by the Massachusetts Clean Energy Center, Microsoft's Climate Innovation Fund, Equinor, Barr Foundation — named seven companies to its second cohort and six to its inaugural batch in 2022. The 13 companies across two cohorts so far have received $325,000 in grant funding from the program.

"These BIPOC-led startups are developing climate technologies that will lead us to a more equitable and sustainable future," MassCEC CEO Dr. Emily Reichert, the former CEO of Greentown, said of the second cohort in a news release. "We want ALL climatetech innovators and entrepreneurs to thrive here in Massachusetts. We are proud to support the ACCEL accelerator, created and led by Greentown Labs and Browning the Green Space. The ACCEL program is helping us build a more diverse innovation ecosystem by breaking down barriers and expanding opportunities."

Houston startup rings NYSE closing bell

A Houston company got to take the national stage by ringing the closing bell at the New York Stock Exchange, and for Katie Mehnert, founder of ALLY Energy, it was a chance to reflect on the progress the industry as a whole has progressed.

"As I stood on the platform at the world’s largest stock exchange to ring the closing bell, surrounded by 130 people from across the energy industry, I saw it clearly: how the private sector will play a major role in getting us to an era of net zero," Mehnert writes in her guest column.

Austin energy startup Base Power opens Katy office & expands Houston service

power move

An Austin startup that pairs electricity with backup power has started doing business in Houston.

Base Power announced this spring that it was entering the Houston market, with an initial focus on Cy-Fair, Spring, Cinco Ranch and Mission Bend. Now, Base Power is offering its service to households within the city of Houston.

To support its growth in the Houston area, Base Power has opened an office and warehouse in Katy. More than 30 people now work there. Plans to expand the Katy location are underway.

Base Power provides electricity that’s complemented by home backup power. Homes don’t need to be using solar power to sign up for Base Power’s service.

The startup said its service automatically supplies power to a home when the electric grid fails.

“Unlike traditional backup systems with high upfront costs, Base earns revenue by providing services to the grid — enabling Houstonians to get reliable backup and real savings,” Base Power said.

In addition to its standard service, Base Power has begun offering technology known as the Generator Recharge Port. This component allows a portable generator to plug into the Base battery system to recharge batteries during extended power outages.

“Houston has long been the energy capital of Texas, yet it has also endured some of the nation’s most painful lessons about unreliable power,” said Zach Dell, co-founder and CEO of Base Power. “We see Houston not just as a place to expand, but as a proving ground for how the future of energy should work — resilient, dependable, and built to serve homeowners when it matters most.”

Dell is the only son of Austin tech billionaire Michael Dell, a Houston native.

Base Power’s expansion in Houston adds to its Texas presence. The company now serves homeowners in the Houston, Dallas-Fort Worth and Austin areas. A partnership with homebuilder Lennar and collaborations with two utilities, GVEC and the Bandera Electric Cooperative, are helping drive Base Power’s business.

Base Power has raised more than $270 million in funding since its founding in 2023. This includes a $200 million series B round that will help finance construction of the company’s first factory in Texas and help fuel Base Power’s national expansion.

The startup’s investors include Andreessen Horowitz, Lightspeed Venture Partners, Valor Equity Partners, Thrive Capital, Altimeter, Terrain and Trust.

"Revterra is thrilled to be a founding member of the EnergyTech Nexus community," Ben Jawdat, founder and CEO of kinetic battery technology company Revterra, added. "Building a strong network of collaborators, customers, and investors is critical for any startup — particularly when you're building novel hardware. The Energytech Nexus community has been incredible at bringing all of the right stakeholders together."

Other partners, many of which have a strong presence in Houston, include:

BBVA
EarthX
Endress+Hauser
Goodwin
Greenbackers Investment Capital
ISR Energy
Latham & Watkins LLP
Ormazabal
Repsol
STX Next
XGS Energy

Jason Ethier, co-founding partner of EnergyTech Nexus, said that partnerships with these companies will be "pivotal" in supporting the organization's community of founders and Houston's broader energy transition sector.

“The Energy and Climate industry deploys over $1.5 trillion in capital every year to meet our growing energy demands. Our global founding partners recognize that this energy must be delivered reliably, cost effectively, and sustainably, and have committed to ensuring that technology developed without our ecosystem can find a path to market through testing and piloting in real-world conditions," Ethier said. "The ecosystem they support here solidifies Houston as the global nexus for the energy transition.”

EnergyTech Nexus also recently announced a "strategic ecosystem partnership" with Greentown Labs, aimed at accelerating growth for clean energy startups. Read more here.
