Greentown Houston calls for feedback for developing wet lab space

Greentown Houston has announced it's building a new wet lab facility, and the organization is looking for feedback from its community.

Greentown Labs, which is dual located at their headquarters in Somerville, Massachusetts, and in the Ion District in Houston, has announced earlier this summer that they are building out a wet lab in their Midtown space.

"We have heard from several startups as well as corporate partners in the ecosystem that are looking for wet lab space," says Lara Cottingham, vice president of strategy, policy, and climate impact at Greentown Labs. "Greentown has experience running wet labs from our location in Somerville. We're excited to be able to offer wet lab space to climatetech startups as an additional amenity to the Ion District.

Although Greentown's Boston-area location has wet lab space, Cottingham says the organization is not interested in copying and pasting that same facility. Greentown wants to provide the tools that the Houston ecosystem needs, and that requires getting feedback from its current and potential members.

"We want to announce to the community that this is something we're going to build — but we still need a lot of feedback and input from startups so we can learn what exactly they need or want to see from the wet lab," Cottingham tells InnovationMap. "No two wet labs are the same."

There currently aren't any details available about timeline or specifics of the new facility. Greentown is prioritizing getting feedback from its members and having conversations with potential sponsors and corporate partners.

"Corporate partners are a big part of the ecosystem and the community at Greentown. They can be so many things to our startups — mentors, customers, investors," Cottingham says. "And in this space, they can help us sponsor and financially support the wet lab. We're still fundraising — we have some partners that have committed to funding, but we're still looking for more funding."

In addition to monetary contribution, Cottingham says they are looking for other options as well, from partnerships with equipment providers, hazardous materials management, and more.

Startups that need wet lab space are encouraged to fill out the online form, which will be open through the summer, and potential corporate partners can express their interest online as well.

Greentown Houston opened its doors in 2021 and has since grown to house more than 75 energy and climatetech startups, as well as several accelerators, thanks to support from dozens of corporate partners.

Engineers at Rice University have developed a cleaner, innovative process to turn end-of-life lithium-ion battery waste into new lithium feedstock.

The findings, recently published in the journal Joule, demonstrate how the team’s new “recharge-to-recycle” reactor recharges the battery’s waste cathode materials to coax out lithium ions into water. The team was then able to form high-purity lithium hydroxide, which was clean enough to feed directly back into battery manufacturing.

The study has major implications for the electric vehicle sector, which significantly contributes to the waste stream from end-of-life battery packs. Additionally, lithium tends to be expensive to mine and refine, and current recycling methods are energy- and chemical-intensive.

“Directly producing high-purity lithium hydroxide shortens the path back into new batteries,” Haotian Wang, associate professor of chemical and biomolecular engineering, co-corresponding author of the study and co-founder of Solidec, said in a news release. “That means fewer processing steps, lower waste and a more resilient supply chain.”

Sibani Lisa Biswal, chair of Rice’s Department of Chemical and Biomolecular Engineering and the William M. McCardell Professor in Chemical Engineering, also served as co-corresponding author on the study.

“We asked a basic question: If charging a battery pulls lithium out of a cathode, why not use that same reaction to recycle?” Biswal added in the release. “By pairing that chemistry with a compact electrochemical reactor, we can separate lithium cleanly and produce the exact salt manufacturers want.”

The new process also showed scalability, according to Rice. The engineers scaled the device to 20 square centimeters, then ran a 1,000-hour stability test and processed 57 grams of industrial black mass supplied by industry partner Houston-based TotalEnergies. The results produced lithium hydroxide that was more than 99 percent pure. It also maintained an average lithium recovery rate of nearly 90 percent over the 1,000-hour test, showing its durability. The process also worked across multiple battery chemistries, including lithium iron phosphate, lithium manganese oxide and nickel-manganese-cobalt variants.

Looking ahead, the team plans to scale the process and consider ways it can sustain high efficiency for greater lithium hydroxide concentrations.

“We’ve made lithium extraction cleaner and simpler,” Biswal added in the release. “Now we see the next bottleneck clearly. Tackle concentration, and you unlock even better sustainability.
