Greentown Labs has named the six participating climatetech startups for an accelerator for a global energy leader.

Shell and Greentown Labs announced the cohort for Greentown Go Make 2023 — a program designed to accelerate partnerships between startups and corporates to advance carbon utilization, storage, and traceability solutions with manufacturing in mind. Shell, which invests in net-zero and carbon-removal technologies, is hoping to strategically align with startups within carbon utilization, storage, and traceability across the energy transition spectrum.

“At Greentown Labs we recognize and appreciate the role energy incumbents must play in the energy transition, and we’re eager to facilitate meaningful partnerships between these impressive startups and Shell—not only to advance these technologies but also to help Shell achieve its sustainability goals,” Kevin Knobloch, CEO and President of Greentown Labs, says in a news release. “We know carbon utilization, storage, and traceability will play a critical role in our collective efforts to reach net-zero, and we’re enthusiastic about the potential impact these companies can have in that work.”

The cohort, selected from 110 applications, is co-located at Greentown's Houston and Somerville, Massachusetts, locations and includes:

  • Portland-based Caravel Bio is developing a novel synthetic biology platform that uses microbial spores and enzymes to create catalysts that are long-lasting and can withstand extreme conditions and environments.
  • Circularise, which is based in the Netherlands, is developing a blockchain platform that provides digital product passports for end-to-end traceability and secure data exchange for industrial supply chains.
  • Corumat, based in Washington, converts organic waste into high-performance, insulating, greaseproof, and biodegradable packaging materials.
  • Cambridge, Massachusetts-headquartered Lydian develops a fully electrified reactor that can convert a variety of gaseous, non-fossil feedstocks into pure syngas with high efficiency.
  • Maple Materials from Richmond, California is developing a low-cost electrolysis process to split carbon dioxide into graphite and oxygen.
  • Ontario, Canada-founded Universal Matter develops a proprietary Flash Joule Heating process that converts carbon waste into high-value and high-performance graphene materials to efficiently create sustainable circular economies.

The program, which includes $15,000 in non-dilutive stipend funding for each company, will work closely with Shell and Greentown over six months via mentorship, networking opportunities, educational workshops, and partnership-focused programming to support collaboration. Go Make 2023 concludes with a showcase event on March 27 at Greentown Labs’ Houston location.

This week, Shell announced another accelerator cohort it's participating in. The Shell GameChanger Accelerator, a partnership with the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL), named four West Coast climatetech companies: DTE Materials, Hexas Biomass, Invizyne Technologies, and ZILA BioWorks. The program provides early-stage cleantech startups with access to experts and facilities to reduce technology development risk and accelerate commercialization of new cleaner technologies.

“Tackling the climate challenge requires multifaceted solutions. At Shell, we believe technology that removes carbon dioxide from the atmosphere will be essential for lowering emissions from energy and chemical products,” Yesim Jonsson, Shell’s GCxN program manager, says in a statement. “The companies in GCxN's sixth cohort embody these objectives and have the potential to usher in a more sustainable future.”

Houston-based Nexalin Technology is taking a medicine-free approach to target brain neurologically associated with mental illness. The company's patented, FDA-cleared frequency-based waveform targets key centers of the midbrain. Delivered via a non-invasive device, the treatment gently stimulates the hypothalamus and midbrain, helping to “reset networks associated with symptoms” of anxiety and insomnia.

Nexalin’s proprietary neurostimulation device moved forward with a clinical trial that evaluated its treatment of anxiety disorders and chronic insomnia in Brazil this year and enrolled the first patients in its clinical trial at the University of California, San Diego. Continue reading.

Houston hailed as one of America's 10 best cities for startups

Startup Report

Houston's favorable economic climate is enticing new opportunities for entrepreneurship and growth, and now the city is being hailed as the 7th-best U.S. city for starting a business.

The recognition comes in CommercialCafe's recent "Best Cities for Startups" report, published December 10. The study analyzed large U.S. cities across two population categories – cities with more than 1 million residents and cities with populations between 500,000 and 1 million residents. The report analyzed relevant metrics such as office or coworking costs, Kickstarter funding success, startup density, and survival rates, among others.

Across the biggest U.S. cities with over a million residents, Phoenix, Arizona landed on top as the No. 1 best place to start a new business.

The report's findings revealed 10.6 percent of all businesses in Houston are startups that have been active for less than a year. These new businesses have a survival rate of 64.5 percent, meaning just under two-thirds of all startups in the city will still be running up to five years after they were first established.

Over the last five years, the number of new businesses established in Houston has grown nearly 15 percent. CommercialCafe said new businesses in cities with high startup growth rates tend to "attract top talent" which can eventually lead to securing "vital funding for expansion."

Independent professionals – also known as freelancers – are another crucial resource for new businesses that may need "specialized services" for a fixed amount of time, the report said. Houston's freelance workforce has grown about 9 percent from 2019-2023, and the analysis found there were 97,295 freelancers working in Houston in 2023, compared to 89,528 in 2019.

"Generally, cities in the South and Southwest have experienced strong growth during the surveyed period, in contrast to California cities like Los Angeles and San Diego, where the share of freelancers and gig workers has either stagnated or slightly declined," the report said.

Houston boasts the second-cheapest office space rent nationally, the report found. The average asking price for a 1,000-square-foot workspace (for five employees) in the city added up to $27,124 annually. For startups that want greater flexibility for their workers, the annual cost for a coworking space for the same number of employees in Houston came out to $13,200, which is the fourth-most affordable rate in the U.S.

Other Texas cities with attractive economic environments for startups

Texas, as a whole, is one of the strongest states for starting a new business. Other than Houston, San Antonio (No. 2), Dallas (No. 3), and Fort Worth (No. 4) were also recognized among the top 10 best places to start a business in the category of U.S. cities with more than a million residents.

Austin topped a separate ranking of best cities to start a business with 500,000 to 1 million residents.

"Specifically, the Texas capital was the frontrunner for indicators that looked at the overall share of startups within the local economy, as well as growth rates in five years (2019 to 2023)," the report said. "On top of that, Austin also topped the rankings for its percentage of college-educated residents and its consulting firms, which provide vital support for burgeoning enterprises."

The top 10 best cities to start a new business are:

  • No. 1 – Phoenix, Arizona
  • No. 2 – San Antonio, Texas
  • No. 3 – Dallas, Texas
  • No. 4 – Fort Worth, Texas
  • No. 5 – Jacksonville, Florida
  • No. 6 – San Diego, California
  • No. 7 – Houston, Texas
  • No. 8 – Philadelphia, Pennsylvania
  • No. 9 – Chicago, Illinois
  • No. 10 – Los Angeles, California

Two federal lawmakers from Texas spearheaded a campaign to relocate NASA’s headquarters from Washington, D.C., to the Johnson Space Center in Houston’s Clear Lake area. Houston faces competition on this front, though, as lawmakers from two other states are also vying for this NASA prize. With NASA’s headquarters lease in D.C. set to end in 2028, U.S. Sen. Ted Cruz, a Texas Republican, and U.S. Rep. Brian Babin, a Republican whose congressional district includes the Johnson Space Center, wrote a letter to President Trump touting the Houston area as a prime location for NASA’s headquarters.
