A new accelerator focused on BIPOC-led energy tech startups named its inaugural cohort, and two Houston-based companies made the cut.

The new program — Advancing Climatetech and Clean Energy Leaders Program, or ACCEL — is an initiative led by Greentown Labs and Browning the Green Space that was originally announced in November. The program was established to provide access to funding, networking connections, resources, and more to BIPOC-led startups working on a climatetech solution.

The program is supported by the Massachusetts Clean Energy Center, or MassCEC, a state economic development agency, and the Boston-based Barr Foundation, a Boston-based foundation. Each of the selected startups will receive a $25,000 grant, incubation at Greentown, mentorship from Greentown and BGS’s networks, and access to a curriculum curated by VentureWell, a nonprofit with deep expertise in the climatetech space.

“We are thrilled and eager to support this exceptional cohort of startup leaders as they tackle some of our world’s biggest climate challenges,” says Kevin T. Taylor, CFO and interim CEO at Greentown Labs, in a news release. “Through partnerships with Browning the Green Space and VentureWell—and with the support from MassCEC and the Barr Foundation—we look forward to offering intentional mentorship, training, and networking opportunities to help these BIPOC-led startups thrive.”

The co-located program will host startups at each of the two Greentown Labs locations in the Houston and Boston areas. The inaugural cohort includes:

  • Active Surfaces, based in Salem, Massachusetts, unlocks dual land-use applications through its ultra-thin-film, flexible solar technology. Its co-founders are Shivam Bhakta and Richard Swartwout.
  • Houston-based DrinKicks is a sneaker-themed consumer-products company that is focused on repurposing food waste and recycled materials into sustainable goods such as shoes, sports equipment, and clothing, all while educating consumers on the power of the circular economy. The company was co-founded by Kristeen Reynolds, Michael Fletcher, and Kristen Lee.
  • EarthBond, headquartered in Cambridge, Massachusetts, leverages group financing and carbon accounting to lower costs and risk in the energy transition of Nigeria's $14B fuel-based, off-grid generator market. Chidalu Onyenso founded the business.
  • Amherst, Massachusetts-based florrent is a bio-based materials and energy storage company providing solutions to address critical bottlenecks to the global decarbonization and electrification of utilities, transportation, and buildings. Its co-founders are Jose LaSalle, Joe Hastry, and Alexander Nichols. florrent is a current Greentown member.
  • frakktal, founded in Houston by Jhana Porter, is a B2B materials company developing bio-based polymer processes for the replacement of fossil-fuel-based feedstocks across industries. The company is a current Greentown member.
  • SpadXTech from Worcester, Massachusetts, is contributing to the reduction of CO2 emissions impacting several industries such as packaging, textiles, transportation, filtration, and construction through the manufacturing of its core and versatile material platform technology. Its co-founders are Lina M. González and Connor Crawford.

“We are inspired by and excited to support the wealth of innovation and fresh perspectives on climate solutions offered by our inaugural ACCEL cohort of startup leaders,” said Kerry Bowie, executive director and president of Browning the Green Space. “Through this partnership with Greentown Labs we are able to build critical support infrastructure for entrepreneurs of color and accelerate the equitable development and distribution of climate solutions across all communities.”

The program will officially kick off at an event on February 23 at Greentown’s Boston location.

Houston maritime startup raises $43M to electrify vessels, opens new HQ

Maritime Mission

A Houston-based maritime technology company that is working to reduce emissions in the cargo and shipping industry has raised VC funding and opened a new Houston headquarters.

Fleetzero announced that it closed a $43 million Series A financing round this month led by Obvious Ventures with participation from Maersk Growth, Breakthrough Energy Ventures, 8090 Industries, Y Combinator, Shorewind, Benson Capital and others. The funding will go toward expanding manufacturing of its Leviathan hybrid and electric marine propulsion system, according to a news release.

The technology is optimized for high-energy and zero-emission operation of large vessels. It uses EV technology but is built for maritime environments and can be used on new or existing ships with hybrid or all-electric functions, according to Fleetzero's website. The propulsion system was retrofitted and tested on Fleetzero’s test ship, the Pacific Joule, and has been deployed globally on commercial vessels.

Fleetzero is also developing unmanned cargo vessel technology.

"Fleetzero is making robotic ships a reality today. The team is moving us from dirty, dangerous, and expensive to clean, safe, and cost-effective. It's like watching the future today," Andrew Beebe, managing director at Obvious Ventures, said in the news release. "We backed the team because they are mariners and engineers, know the industry deeply, and are scaling with real ships and customers, not just renderings."

Fleetzero also announced that it has opened a new manufacturing and research and development facility, which will serve as the company's new headquarters. The facility features a marine robotics and autonomy lab, a marine propulsion R&D center and a production line with a capacity of 300 megawatt-hours per year. The company reports that it plans to increase production to three gigawatt-hours per year over the next five years.

"Houston has the people who know how to build and operate big hardware–ships, rigs, refineries and power systems," Mike Carter, co-founder and COO of Fleetzero, added in the release. "We're pairing that industrial DNA with modern batteries, autonomy, and software to bring back shipbuilding to the U.S."

New cancer-fighting nanodrug tops Houston innovation news to know

Trending News

Editor's note: The new year brings big Houston innovation news, from pending retirements to new hires and a cancer-fighting nanodrug. Below are the five most-read InnovationMap stories published January 16-30, 2026:

1. Houston team uses CPRIT funding to develop nanodrug for cancer immunotherapy

With a relative five-year survival rate of 50 percent, pancreatic cancer is a diagnosis nobody wants. At 60 percent, the prognosis for lung cancer isn’t much rosier. That’s because both cancers contain regulatory B cells (Bregs), which block the body’s natural immunity, making it harder to fight the enemies within. Newly popular immunotherapies in a category known as STING agonists may stimulate natural cancer defenses. However, they can also increase Bregs while simultaneously causing significant side effects. But Wei Gao, assistant professor of pharmacology at the University of Houston College of Pharmacy, may have a solution to that conundrum. Continue reading.

Innovative Houston-area hardtech startup closes $5M seed round

fresh funding

Conroe-based hardtech startup FluxWorks has closed a $5 million seed round.

The funding was led by Austin-based Scout Ventures, which invests in early-stage startups working to solve national security challenges.

Michigan Capital Network also contributed to the round from its MCN Venture Fund V. The fund is one of 18 selected by the Department of Defense and Small Business Administration to participate in the Small Business Investment Company Critical Technologies Initiative, which will invest $4 billion into over 1,700 portfolio companies.

FluxWorks reports that it will use the funding to drive the commercialization of its flagship Celestial Gear technology.

"At Scout, we invest in 'frontier tech' that is essential to national interest. FluxWorks is doing exactly that by solving critical hardware bottlenecks with its flagship Celestial Gear technology ... This is about more than just gears; it’s about strengthening our industrial infrastructure," Scout Ventures shared in a LinkedIn post.

Fluxworks specializes in making contactless magnetic gears for use in extreme conditions, which can enhance in-space manufacturing. Its contactless design leads to less wear, debris and maintenance. Its technology is particularly suited for space applications because it does not require lubricants, which can be difficult to control at harsh temperatures and in microgravity.

The company received a grant from the Texas Space Commission last year and was one of two startups to receive the Technology in Space Prize, funded by Boeing and the Center for the Advancement of Science in Space (CASIS), in 2024. It also landed $1.2 million through the National Science Foundation's SBIR Phase II grant this fall.

Fluxworks was founded in College Station by CEO Bryton Praslicka in 2021. Praslicka moved the company to Conroe 2024.
