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.”

Harris County booms with 3rd biggest population in U.S.

Boomtown

Newly released U.S. Census Bureau data has revealed Harris County became the third most populous county nationwide in 2024, and it had the highest year-over-year growth rate from 2023.

The new population report, published this month, estimated year-over-year population data from 2023 to 2024 across all 3,144 U.S. counties, and 387 metro areas.

Harris County's numeric growth rate outpaced all other U.S. counties from July 1, 2023 to July 1, 2024, the report found. The Census Bureau estimated Harris County's population grew by 105,852 people year-over-year, bringing the total population to 5,009,302 residents. That's around a 2.16 percent growth rate.

Los Angeles County, California (No. 1) and Illinois' Cook County (No. 2) are the only two U.S. counties that have larger populations than Harris County. Los Angeles County now boasts a population of nearly 9.76 million, while Cook County's has increased to more than 5.18 million people.

The top 10 most populous counties in the U.S. are:

  • No. 1 – Los Angles County, California
  • No. 2 – Cook County, Illinois
  • No. 3 – Harris County, Texas
  • No. 4 – Maricopa County, Arizona
  • No. 5 – San Diego County, California
  • No. 6 – Orange County, California
  • No. 7 – Miami-Dade County, Florida
  • No. 8 – Dallas County, Texas
  • No. 9 – Kings County, New York
  • No. 10 – Riverside County, California

Montgomery County also ranked among the top 10 U.S. counties with the highest numeric growth, ranking 9th nationally after gaining 34,268 residents from 2023 to 2024. Montgomery County's population has now grown to 749,613 people.

In the report's national comparison of counties with the largest population growth by percentage, Montgomery County ranked No. 7 with a year-over-year growth rate of 4.8 percent.

Most populated U.S. metro areas

The U.S. Census Bureau additionally found Houston-Pasadena-The Woodlands nearly led the nation as the second-fastest growing metro area in 2024.

From July 2023 to July 2024, the Houston metro added 198,171 residents to bring the total population to 7,796,182.

New York-Newark-Jersey City was the only metro area to outpace Houston's growth during the one-year period. The New York-New Jersey metro added 213,403 new residents, which brought the total population to over 19.94 million last year.

Kristie Wilder, a Census Bureau Population Division demographer, said in the report that the nation's population growth in its major metros was largely impacted by international migration rather than changes in birth rates.

"While births continue to contribute to overall growth, rising net international migration is offsetting the ongoing net domestic outmigration we see in many of these areas," Wilder said.

Dallas-Fort Worth-Arlington was right behind Houston as the third-fastest growing U.S. metro in 2024. The Metroplex gained 177,922 residents last year, and now has a total population of more than 8.34 million.

The top 10 U.S. metros with the highest numeric growth from 2023 to 2024 are:

  • No. 1 – New York-Newark-Jersey City, New York-New Jersey
  • No. 2 – Houston-Pasadena-The Woodlands, Texas
  • No. 3 – Dallas-Fort Worth-Arlington, Texas
  • No. 4 – Miami-Fort Lauderdale-West Palm Beach, Florida
  • No. 5 – Washington-Arlington-Alexandria, D.C.-Virginia-Maryland-West Virginia
  • No. 6 – Phoenix-Mesa-Chandler, Arizona
  • No. 7 – Orlando-Kissimmee-Sanford, Florida
  • No. 8 – Atlanta-Sandy Springs-Roswell, Georgia
  • No. 9 – Chicago-Naperville-Elgin, Illinois-Indiana
  • No. 10 – Seattle-Tacoma-Bellevue, Washington

New report reveals how much Texans are warming up to AI

eyes on ai

When new technology emerges, many of us approach it with a certain amount of skepticism. That’s certainly true with artificial intelligence, which is creeping into practically every part of our existence. Pew Research Center surveys show that more than half (52 percent) of Americans are increasingly cautious about the growing presence of AI in their everyday lives.

So, how wary are Texans of AI? A new ranking from ZapCap, whose AI generates captions for videos, gives us a clue. Texas ranks 15th among the states that are most trusting of AI, with a trust score of 85 out of 100.

Translation: Texans appear to be OK with embracing AI.

To develop the ranking, ZapCap collected search volume data for AI-related queries, including terms such as “best AI tools,” “best AI assistants,” “how to use AI” and “ChatGPT.” ZapCap then calculated a trust score based on each state’s search activity and population.

“This research provides an insightful look into AI engagement patterns across the U.S., highlighting the states where AI is most actively explored and potentially trusted,” says ZapCap.

With an off-the-charts score of 116, California tops the list. California “demonstrates extraordinary AI engagement with over 44 million ChatGPT searches and 77,910 Claude.AI queries, marking the highest AI tool adoption rates across all metrics,” says ZapCap.

Here’s the rest of the top five, including their AI trust scores:

  • New York — 108
  • Massachusetts — 106
  • Virginia — 102
  • New Jersey — 99

The state with the least amount of AI trust is Minnesota, which received a ZapCap score of 22.

“What’s fascinating is that innovation is blooming far beyond the usual tech hotspots,” ZapCap’s Jessica Bui said in a release. “While California and New York continue to lead, states like Massachusetts and Virginia are rising as innovation powerhouses. Their rapid adoption of new technology proves that it's not about market size — it’s about fostering a culture where businesses and everyday people feel confident exploring what's next.”
