After six months of incubating with Shell through Greentown Labs, the 2023 Greentown Go Make startup cohort has completed with its recent showcase.

The six participating startups — Caravel Bio, Circularise, Corumat, Lydian, Maple Materials, and Universal Matter — were originally announced in October. The cohort was selected from over 100 applications, and experts from Shell worked to support the cohort as they navigated the program.

Universal Matter, headquartered in Burlington, Ontario, Canada, with a Houston office, is developing a proprietary flash Joule heating process that converts carbon waste into high-value and high-performance graphene materials to efficiently create sustainable, circular economies.

During the program, Universal Matter worked with Shell to identify eight potential collaboration areas across upstream carbon feedstocks, downstream end-use applications for the startup’s graphene, and more, according to a news release from Greentown.

“Go Make 2023 was run with exceptional efficiency to ensure that all startup members were able to gain maximum benefit from exchanges with the corporate partner,” says Universal Matter’s VP of Strategic Planning Peter van Ballegooie.

“The one-on-one exchanges were extremely useful to startups, as they facilitated the connections to the relevant business units within Shell that could potentially benefit from the novel technologies being developed," he continues. "Establishing the connectivity to the right discussion partners within those various business units was absolutely key to the successful outcome of the program.”

Greentown shared more about each of the company's progress throughout the program in a blog post.

Greentown Labs names 6 energy tech startups to Shell-backed accelerator

ready to go make

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. 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.”

“Through this fellowship program, we can support outstanding graduate students from across the university who are conducting cutting-edge research across a variety of fields,” Carrie Masiello, director of the Rice Sustainability Institute, said in a news release. “This year, our 2026 Chevron Fellows are working on research that reflects the diversity of the sustainability research at Rice … and these scholarly endeavors exemplify the breadth and depth of research enabled by Chevron’s generous support.”

The Chevron Fellows program launched at Rice last year, naming 10 graduate students to the inaugural cohort. It is funded by Chevron and was created through a partnership between the Rice Sustainability Institute. Chevron launched a similar program at the University of Houston in 2023.

“Rice University continues to be an exceptional partner in advancing energy innovation,” Chris Powers, director of exploration commercial and portfolio at Chevron, added in the release. “The Chevron Energy Fellows program showcases the brilliance and drive of Rice graduate students, whose research in areas like carbon conversion, solar materials and geothermal sensing is already shaping the future of sustainable energy. We’re proud to celebrate their achievements and look forward to the impact they’ll continue to make across the energy landscape.”

Houston clean energy company to develop hybrid renewable project in Port Arthur

power project

Houston-based clean energy company Diligence Offshore Services has announced a strategic partnership with Florida-based floating solar manufacturing company AccuSolar for the development of a renewable energy project in the Port Arthur area.

Known as the Pleasure Island Power Collective, it will be built on 2,275 acres across Pleasure Island and Sabine Lake. It is expected to generate 391 megawatts of clean power, alongside a utility-scale battery energy storage system. It will also feature a 225-megawatt coastal onshore wind farm, with energy produced on-site used to power a data center for adaptive superintelligence, making it entirely self-sustained by renewable sources, according to the company.

AccuSolar will design and manufacture the project and power will be distributed through the Canaan Energy Corridor

“We are incredibly proud to partner with a fellow U.S. company like AccuSolar,” Harry C. Crawford III, founder and managing member of Diligence Offshore, said in a news release. “Their expertise in American manufacturing and floating solar technology is essential to the success of the Pleasure Island Power Collective.”

The project is expected to bring economic growth and a significant number of manufacturing jobs to the area during the construction phase and long-term operations.

Diligence Offshore is pursuing a DPA Title 1 DX rating under the Defense Production Act to help advance the project's development schedule, according to the release, which could lead to immediate manufacturing jobs.

“This partnership not only strengthens our domestic supply chain but also accelerates our vision to bring economic freedom and climate resilience to the Gulf Coast,” Crawford added in the release.
