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.”

Syzygy inks long-term offtake agreement for first commercial SAF plant

fuel deal

Houston-based Syzygy Plasmonics has secured a six-year official offtake agreement for the entire production volume of its first commercial-scale biogas-to-sustainable aviation fuel project in Uruguay, known as NovaSAF-1.

SP Developments Uruguay S.A., a subsidiary of Syzygy, entered into the agreement with Singapore-based commodity company Trafigura, according to a news release. There is also an option for Trafigura to purchase additional volumes from future Syzygy projects.

The first deliveries from the landmark SAF facility are expected in 2028.

“This agreement marks a critical step in our journey toward commercial-scale impact and disrupting the SAF market,” Trevor Best, CEO of Syzygy Plasmonics, said in the news release. “With a signed offtake agreement from a global leader like Trafigura, and after having successfully completed FEED engineering in December, we're now ready to secure financing for the construction of NovaSAF-1 and move our technology from potential into production."

The NovaSAF-1 project will be located in Durazno, Uruguay. The facility will be the world's first electrified biogas-to-SAF facility producing renewable and advanced compliant SAF. Syzygy estimates that the project will produce over 350,000 gallons of SAF annually. The facility is expected to produce SAF with at least an 80 percent reduction in carbon intensity compared to Jet A fuel.

It’s backed by Uruguay’s largest dairy and agri-energy operations, Estancias del Lago. It will also work with Houston-based Velocys, which will provide Fischer-Tropsch technology for the project. Fischer-Tropsch technology converts synthesis gas into liquid hydrocarbons, which is key for producing synthetic fuels like SAF.

ERCOT to capture big share of U.S. solar power growth through 2027

solar growth

Much of the country’s growth in utility-scale solar power generation will happen in the grid operated by the Electric Reliability Council of Texas (ERCOT), according to a new forecast.

The U.S. Energy Information Administration (EIA) predicts that solar power supplied to the ERCOT grid will jump from 56 billion kilowatt-hours in 2025 to 106 billion kilowatt-hours by the end of 2027. That would be an increase of 89 percent.

In tandem with the rapid embrace of solar power, EIA anticipates battery storage capacity for ERCOT will expand from 15 gigawatts in 2025 to 37 gigawatts by the end of 2027, or 147 percent.

EIA expects utility-scale solar to be the country’s fastest-growing source of power generation from 2025 to 2027. It anticipates that this source will climb from 290 billion kilowatt-hours last year to 424 billion kilowatt-hours next year, or 46 percent.

Based on EIA’s projections, ERCOT’s territory would account for one-fourth of the country’s utility-scale solar power generation by the end of next year.

“Solar power and energy storage are the fastest-growing grid technologies in Texas, and can be deployed more quickly than any other generation resource,” according to the Texas Solar + Storage Association. “In the wholesale market, solar and storage are increasing grid reliability, delivering consumer affordability, and driving tax revenue and income streams into rural Texas.”
