Calling all cleantech startups founded by innovators of color — an inclusive accelerator program is now accepting applications.

Advancing Climatetech and Clean Energy Leaders Program, or ACCEL, has opened applications for it's second cohort. The program — from Greentown Labs and Browning the Green Space — provides access to funding, networking connections, incubation space, mentorship, resources, and opportunities for energy tech founders of color for a year.

“ACCEL is one of the most impactful, meaningful programs we’ve run to date,” Greentown Labs CEO and President Kevin Knobloch says in a news release. “We are eager to expand upon the great success and momentum of year one, 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.”

The program, supported by the Massachusetts Clean Energy Center, accelerated six startups this year — Active Surfaces, DrinKicks, EarthBond, florrent, frakktal, and SpadXTech.

“The ACCEL Program directly aligns with our mission to ensure that climatetech jobs and wealth creation opportunities are available to all residents of the Commonwealth,” Emily Reichert, CEO at MassCEC and former CEO at Greentown, says in the release. “We are excited to see the second round of this important program, with our Equity Workforce Fund support fostering a partnership between Greentown Labs and Browning the Green Space aimed at accelerating the growth of minority and women business enterprises in Massachusetts.”

ACCEL, which doles out $25,000 in non-dilutive grant funding to each participant, is also supported by Boston-based Barr Foundation and provides programming from VentureWell, a nonprofit with expertise in climatetech.

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

Applications for ACCEL are open until January 5, 2024. While entrepreneurs from anywhere can apply, preference will be given to applicants in Greater Boston and Greater Houston, where Greentown’s incubators are located.

Rice University researchers have uncovered a more energy-efficient and faster way to recycle critical minerals from used lithium-ion batteries.

Traditional methods rely on high heat, long processing times and harsh chemicals to recover a small fraction of critical materials from batteries used in everything from smartphones to electric vehicles. However, the team from Rice's Department of Materials Science and Nanoengineering developed a process that uses a water-based solution containing amino chlorides to extract more metals in less time

The team published the findings in a recent edition of the scientific journal Small.

Simon King, a sophomore studying chemical and biomolecular engineering who completed this work as a summer research fellow at the Rice Advanced Materials Institute, served as first author of the study. He worked with corresponding authors Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering, and Sohini Bhattacharyya, a research scientist in Ajayan’s lab.

By using a hydroxylammonium chloride (HACI) solution, the team achieved roughly 65 percent extraction of key battery metals in just one minute at room temperature, according to the study. The efficiencies grew to roughly 75 percent for several metals under longer processing times.

“We were surprised by just how fast the reaction occurs, especially without the involvement of high temperatures,” King said in a news release. “Within the first minute, we’re already seeing the majority of the metal extraction take place.”

By not requiring high temperatures or long reaction times, Rice predicts the process could have a major impact on cost and the environmental impact of lithium battery recycling. Additionally, the water-based HACI solution makes waste handling easier and lowers certain environmental risks.

In addition to extracting the materials, the team went on to demonstrate that the recovered metals could be recycled and reprocessed into new battery materials.

“A big advantage of this system is that it works under relatively mild conditions,” Ajayan added in the release. “That opens the door to more sustainable and scalable recycling technologies.”
