An accelerator focused on supporting BIPOC-led climatetech startups and addressing inequities in the climatetech industry is accepting applications for its second cohort.

Greentown Labs, the largest climatetech incubator in North America, and Browning the Green Space (BGS), a nonprofit dedicated to making clean energy and other climate-related fields more diverse, equitable, and inclusive, lead the Advancing Climatetech and Clean Energy Leaders Program (ACCEL), which offers access to funding, networking connections, resources, and opportunities that structural inequities put out of reach.

“Opening applications for Year 2 of ACCEL is an important milestone in strengthening critical support for traditionally excluded entrepreneurs in our communities,” says Kerry Bowie, executive director and president of Browning the Green Space.

Benefits for startups accepted into the ACCEL program include:

  • gaining access to extensive mentorship from industry experts
  • $25k in non-dilutive grant funding
  • a curated curriculum of workshops led by experts — including from VentureWell — covering various essential topics for early-stage climatetech founders, such as customer discovery, design-thinking, startup finance, storytelling, and more

“Through our partnership with Greentown and VentureWell, we are able to put our respective strengths together to create an ambitious program to bolster founders of color in climatetech and propel innovations that benefit communities most impacted by climate change,” Bowie says.

For Year 2 of ACCEL, Greentown and BGS are seeking applications from startups at Technology Readiness Levels (TRL) 1-4 that are developing climate solutions for the electricity, transportation, buildings, manufacturing, agriculture, and resiliency and adaptation sectors. Applications are due January 5, 2024.

The Year 2 request for applications comes as a successful inaugural year of ACCEL winds to a close.

ACCEL Year 1 featured six startups working on innovations as diverse as sneakers made from food waste, ultracapacitors built with hemp sourced from Black and Indigenous farmers, and ultra-light solar panels.

Their accomplishments during the accelerator included raising equity funding, earning acceptances into additional accelerators, winning grants, executing customer discovery, and more. Check out more results from Year 1 of ACCEL here.

“ACCEL is one of the most impactful, meaningful programs we’ve run to date,” says Greentown Labs CEO and president Kevin Knobloch. “We are eager to expand upon the great success and momentum of Year 1, and to welcome another incredible cohort of BIPOC-led startups that are developing much-needed climatetech solutions. We’re equally committed to helping these companies accelerate and deploy their solutions, while also helping to build a more diverse, inclusive climatetech workforce — ACCEL sits at the nexus of those two critical efforts.”

Houston researcher builds radar to make self-driving cars safer

eyes on the road

A Rice University researcher is giving autonomous vehicles an “extra set of eyes.”

Current autonomous vehicles (AVs) can have an incomplete view of their surroundings, and challenges like pedestrian movement, low-light conditions and adverse weather only compound these visibility limitations.

Kun Woo Cho, a postdoctoral researcher in the lab of Rice professor of electrical and computer engineering Ashutosh Sabharwal, has developed EyeDAR to help address such issues and enhance the vehicles’ sensing accuracy. Her research was supported in part by the National Science Foundation.

The EyeDAR is an orange-sized, low-power, millimeter-wave radar that could be placed at streetlights and intersections. Its design was inspired by that of the human eye. Researchers envision that the low-cost sensors could help ensure that AVs always pick up on emergent obstacles, even when the vehicles are not within proper range for their onboard sensors and when visibility is limited.

“Current automotive sensor systems like cameras and lidar struggle with poor visibility such as you would encounter due to rain or fog or in low-lighting conditions,” Cho said in a news release. “Radar, on the other hand, operates reliably in all weather and lighting conditions and can even see through obstacles.”

Signals from a typical radar system scatter when they encounter an obstacle. Some of the signal is reflected back to the source, but most of it is often lost. In the case of AVs, this means that "pedestrians emerging from behind large vehicles, cars creeping forward at intersections or cyclists approaching at odd angles can easily go unnoticed," according to Rice.

EyeDAR, however, works to capture lost radar reflections, determine their direction and report them back to the AV in a sequence of 0s and 1s.

“Like blinking Morse code,” Cho added. “EyeDAR is a talking sensor⎯it is a first instance of integrating radar sensing and communication functionality in a single design.”

After testing, EyeDAR was able to resolve target directions 200 times faster than conventional radar designs.

While EyeDAR currently targets risks associated with AVs, particularly in high-traffic urban areas, researchers also believe the technology behind it could complement artificial intelligence efforts and be integrated into robots, drones and wearable platforms.

“EyeDAR is an example of what I like to call ‘analog computing,’” Cho added in the release. “Over the past two decades, people have been focusing on the digital and software side of computation, and the analog, hardware side has been lagging behind. I want to explore this overlooked analog design space.”

12 winners named at CERAWeek clean tech pitch competition in Houston

top teams

Twelve teams from around the country, including several from Houston, took home top honors at this year's Energy Venture Day and Pitch Competition at CERAWeek.

The fast-paced event, held March 25, put on by Rice Alliance, Houston Energy Transition Initiative and TEX-E, invited 36 industry startups and five Texas-based student teams focused on driving efficiency and advancements in the energy transition to present 3.5-minute pitches before investors and industry partners during CERAWeek's Agora program.

The competition is a qualifying event for the Startup World Cup, where teams compete for a $1 million investment prize.

PolyJoule won in the Track C competition and was named the overall winner of the pitch event. The Boston-based company will go on to compete in the Startup World Cup held this fall in San Francisco.

PolyJoule was spun out of MIT and is developing conductive polymer battery technology for energy storage.

Rice University's Resonant Thermal Systems won the second-place prize and $15,000 in the student track, known as TEX-E. The team's STREED solution converts high-salinity water into fresh water while recovering valuable minerals.

Teams from the University of Texas won first and second place in the TEX-E competition, bringing home $25,000 and $10,000, respectively. The student winners were:

Companies that pitched in the three industry tracts competed for non-monetary awards. Here are the companies named "most-promising" by the judges:

Track A | Industrial Efficiency & Decarbonization

Track B | Advanced Manufacturing, Materials, & Other Advanced Technologies

  • First: Licube, based in Houston
  • Second: ZettaJoule, based in Houston and Maryland
  • Third: Oleo

Track C | Innovations for Traditional Energy, Electricity, & the Grid

The teams at this year's Energy Venture Day have collectively raised $707 million in funding, according to Rice. They represent six countries and 12 states. See the full list of companies and investor groups that participated here.
