Cemvita Factory has made big moves in its leadership team. The low-carbon biotech and synthetic biology solution provider has recently made three strategic appointments: Charles Nelson was hired as chief business officer, Roger A. Harris was promoted to chief commercial officer, and Alex Juminaga was recruited as head of strain development.

“Scaling to meet market demand requires the right team at the right time,” says Tara Karimi, co-founder and CTO of Cemvita, in a news release. “With Charlie, Roger, and Alex’s leadership, we’re well-positioned for growth at a time when the demand for decarbonization solutions is greater than ever.”

With over 10 years in product development, engineering, and technology commercialization experience, Nelson will oversee all aspects of sales, business development, and customer success.

“At Cemvita, we create sustainable solutions to challenges across heavy industries,” says Nelson in the release. “Our goal is to reinvent heavy industries in ways that speak to the future, reduce companies’ carbon footprints, and even create jobs; I’m delighted to help lead the charge.”

Harris originally joined Cemvita as vice president of technology commercialization a year ago and has over two decades of experience in research and development, and engineering. In his new role, he is responsible for scaling and commercializing the startup's technology.

“Cemvita is positioned incredibly well to support heavy industry in efforts to innovate, and to help oil and gas diversify offerings and reduce dependency on carbon-intensive products,” says Harris in the release. “It is an exciting time and I’m thrilled to be with Cemvita.”

Lastly, Alex Juminaga will lead the Cemvita biofoundry’s production of novel biomolecules. He brings over a decade of laboratory experience — specializing in metabolic engineering, protein expression/purification, enzyme kinetics and binding assays, analytical chemistry, and more.

“The field of synthetic biology is just getting started, with thousands of microbes yet to be discovered,” says Juminaga. “I’m excited to work alongside the brilliant scientists at Cemvita as we uncover new microbiomes and new uses for these tiny treasures.”

NASA signs on latest tenant for new Exploration Park campus, now underway

space hub

Exploration Park, the 240-acre research and commercial institute at NASA's Johnson Space Center, is ready for launch.

Facilities at the property have broken ground, according to a recent episode of NASA's Houston We Have a Podcast, with a completion date targeted for Q4 2026.

The research park has also added Houston-based KBR to its list of tenants. According to a news release from the Greater Houston Partnership, the human spaceflight and aerospace services company will operate a 45,000-square-foot food innovation lab at Exploration Park. KBR will use the facility to focus on customized food systems, packaging and nutrition for the low Earth orbit economy.

“Exploration Park is designed for companies in the space ecosystem, such as KBR, to develop, produce, and deploy innovative new technologies that support space exploration and commerce,” Simon Shewmaker, head of development at ACMI Properties, the developer behind Exploration Park, said in the GHP release. “This project is moving expeditiously, and we’re thrilled to sign such an innovative partner in KBR, reflecting our shared commitment to building the essential infrastructure of tomorrow for the next generation of space innovators and explorers.”

NASA introduced the concept of a collaborative hub for academic, commercial and international partners focused on spaceflight in 2023. It signed leases with the American Center for Manufacturing and Innovation and the Texas A&M University System for the previously unused space at JSC last year.

“For more than 60 years, NASA Johnson has been the hub of human space exploration,” Vanessa Wyche, NASA Johnson Space Center Director, said in a statement at the time. “This Space Systems Campus will be a significant component within our objectives for a robust and durable space economy that will benefit not only the nation’s efforts to explore the Moon, Mars and the asteroids, but all of humanity as the benefits of space exploration research roll home to Earth.”

Texas A&M is developing the $200 million Texas A&M Space Institute, funded by the Texas Space Commission, at the center of the park. The facility broke ground last year and will focus on academic, government and commercial collaboration, as well as workforce training programs. ACMI is developing the facilities at Exploration Park.

Once completed, Exploration Park is expected to feature at least 20 build-to-suit facilities over at least 1.5 million square feet. It will offer research and development space, laboratories, clean rooms, office space and light manufacturing capabilities for the aerospace, robotics, life support systems, advanced manufacturing and artificial intelligence industries.

According to the GHP, Griffin Partners has also been selected to serve as the co-developer of Exploration Park. Gensler is leading the design and Walter P Moore is overseeing civil engineering.

Houston cleantech co. plans first-of-its-kind sustainable aviation fuel facility

coming soon

Houston-based Syzygy Plasmonics announced plans to develop what it calls the world's first electrified facility to convert biogas into sustainable aviation fuel (SAF).

The facility, known as NovaSAF 1, will be located in Durazno, Uruguay. It is expected to produce over 350,000 gallons of SAF annually, which would be considered “a breakthrough in cost-effective, scalable clean fuel,” according to the company.

"This is more than just a SAF plant; it's a new model for biogas economics," Trevor Best, CEO of Syzygy Plasmonics, said in a news release. "We're unlocking a global asset class of underutilized biogas sites and turning them into high-value clean fuel hubs without pipelines, costly gas separation, or subsidy dependence.”

The project is backed by long-term feedstock and site agreements with one of Uruguay's largest dairy and agri-energy operations, Estancias del Lago, while the permitting and equipment sourcing are ongoing alongside front-end engineering work led by Kent.

Syzygy says the project will result in a 50 percent higher SAF yield than conventional thermal biogas reforming pathways and will utilize both methane and CO2 naturally found in biogas as feedstocks, eliminating the need for expensive CO2 separation technologies and infrastructure. Additionally, the modular facility will be designed for easy replication in biogas-rich regions.

The new facility is expected to begin commercial operations in Q1 2027 and produce SAF with at least an 80 percent reduction in carbon intensity compared to Jet A fuel. The company says that once fully commercialized the facility will produce SAF at Jet-A fuel cost parity.

“We believe NovaSAF represents one of the few viable pathways to producing SAF at jet parity and successfully decarbonizing air travel,” Best added in the release.
