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.”

Booming Houston suburb launches innovation grant to attract startups

innovation incentive

Think you’ve got a burgeoning startup? Consider moving it to southwest Houston. The City of Sugar Land announced the Sugar Land Starts Innovation Fund last week to support companies that move jobs to the area.

“The Sugar Land Starts Innovation Fund is designed to support companies that are ready to grow and make a meaningful, long-term commitment to our community,” Colby Millenbruch, business recruitment manager for the City of Sugar Land, said in a news release. “By focusing on revenue-generating startups and performance-based incentives, we are creating a clear pathway for innovative companies to scale while reenergizing existing office space.”

The performance-based, non-equity dilutive grant program is open to companies that demonstrate at least $250,000 in generated revenue or $500,000 in institutional backing from a bank or venture capital firm. They must commit to hiring or relocating at least three employees in Sugar Land for a minimum of three years and at an average salary of $61,240. Compliance will be verified through Texas Workforce Commission reporting.

The fund builds off the Sugar Land Plug and Play partnership to turn the city into an innovative technology hub.

Collaboration with the Silicon Valley-based startup incubator and accelerator on a physical location in southwest Houston has supported 22 startups and has raised $6.5 million in capital since it officially launched in Sugar Land last March. Companies located at the Sugar Land Plug and Play include Synaps, a browser-based design platform for architects, and Intero Biosystems, which produces miniature human organs for preclinical drug development.

In addition to direct funding and business space, both the new grant and the overall Plug and Play project facilitate meetings with Houston-area businesses like CenterPoint Energy.

This should not only bring new industries to Sugar Land, but also allow existing companies to expand outward as technological investors to create a web of new progress.

“This investment is about more than technology. It’s about creating an environment where innovation can take root, grow, and deliver lasting value for the Sugar Land community,” David Steele, director of Texas at Plug and Play, added in the release. “Sugar Land is setting itself apart by taking a long-term view, investing in founders, partnerships, and technologies that will define the next chapter of growth. We’re proud to partner with the city in building an innovation ecosystem that benefits both entrepreneurs and the broader community.”

Income study shows $100,000 salary goes further in Houston in 2026

Money Talk

A 2026 income study has good news for big earners in Houston: A six-figure salary goes further than it did last year.

A Houston resident's $100,000 salary is worth $84,840 after taxes and adjusted for the local cost of living, according to the new financial analysis from SmartAsset. That's about $1,500 more than Houstonians were bringing home last year.

The 2026 take-home pay is about 8 percent higher than it was in 2024, when the same salary had an adjusted value of $78,089.

SmartAsset used its paycheck calculator to apply federal, state and local taxes to an annual salary of $100,000 in 69 of the largest American cities. The figure was then adjusted for the local cost of living (which included average costs for housing, groceries, utilities, transportation, and miscellaneous goods and services). Cities were then ranked based on where a six-figure salary is worth the least after applicable taxes and cost of living adjustments.

Houston ranked No. 60 in the overall ranking of U.S. cities where $100,000 is worth the least. If the rankings were flipped and the cities were ranked based on where $100,000 goes the furthest, that places Houston in the No. 10 spot nationwide.

Manhattan, New York remains the No. 1 city where a six-figure salary is worth the least. A Manhattan resident's take-home pay is only worth $29,420 after taxes and adjusted for the cost of living, which is 3.10 percent lower than it was in 2025.

SmartAsset determined Manhattan has a 29.7 percent effective tax rate on six-figure salaries. Meanwhile, the effective tax rate on a $100,000 salary in Texas (based on the eight cities examined in the report) is 21.1 percent. It's worth highlighting that New York implements a statewide graduated-rate income tax from 4-10.90 percent, whereas Texas is one of only eight states that don't tax residents' income.

Oklahoma City, No. 69, is the U.S. city in the report where a $100,000 salary stretches the furthest. A six-figure salary is worth $91,868 in 2026, up from $89,989 last year.

This is the post-tax value of a $100,000 salary in other Texas cities, and their ranking in the report:

  • Plano (No. 27): $72,653
  • Dallas (No. 47): $80,103
  • Austin (No. 53): $82,446
  • Lubbock (No. 59): $84,567
  • San Antonio (No. 62): $86,419
  • El Paso (No. 67): $90,276
  • Corpus Christi (No. 68): $91,110
According to the report, getting some "financial breathing room" by making six-figures really depends on where someone lives and what their lifestyle is. For residents living in the 42 states that levy some amount of income tax, their take-home pay dwindles further."And depending on how taxes are filed, reaching a $100,000 income may push a household from the 22 percent to 24 percent marginal tax bracket," the report's author wrote. "Meanwhile, locations with high costs across housing and everyday essentials may be less forgiving to a $100,000 income."

Rice University partners with astronaut foundation to offer new STEM scholarship

space scholars

Rice University has partnered with The Astronaut Scholarship Foundation (ASF) to offer a new scholarship opportunity for junior or senior STEM majors, beginning this spring.

The prestigious Astronaut Scholarship includes up to $15,000, mentorship, networking and a paid trip to the ASF Innovators Symposium and Gala. The scholarship is funded by the James A. Lovell Jr. Family Endowment, in honor of the late American astronaut and founder of the ASF.

“This scholarship opportunity represents an exciting new avenue for Rice STEM students to synthesize their experiences in courses and research and their commitment to advancing the public good as leaders in their field,” Danika Brown, executive director for the Center for Civic Leadership at Rice, said in a news release. “We are so grateful to the Lovell family and to the foundation for investing in Rice students, and we are confident that the foundation will be impressed with our nominees and that selected students will have a life-changing experience as astronaut scholars.”

The Rice Space Institute and the Center for Civic Learning recently hosted the ASF at the Ralph S. O’Connor Building for Engineering and Science.

At the ASF event, Jeff Lovell—son of James Lovell, who commanded Apollo 13 and flew on Apollo 8—announced the scholarship aimed at Rice STEM students. Charlie Duke, who served as spacecraft communicator for the Apollo 11 Moon landing and as the lunar module pilot for Apollo 16, also spoke at the event.

The ASF awarded 74 scholarships to students from 51 universities across the U.S. last May.

The ASF awarded its first seven $1,000 scholarships in 1986 to pay tribute to the Mercury 7 astronauts. It has since awarded more than $10 million to more than 850 college students.

So far, only students from Texas A&M University and the University of Texas at Austin have received the scholarship in Texas.
