Houston’s Greentown Labs announced new resources and equipment for its members thanks to two corporate partnerships.

Greentown Houston is now home to new tools from Emerson and Puffer to help members implement strong foundations for access to contextualized data.

Automation is the theme with the latest resources, as the process assists with a startup's journey to “standardization and scalability” according to a news release from Greentown Labs. Members will have access to these two units and platforms. The DeltaV Automation Platform is a data-driven decision-making resource that aims to improve operational performance while reducing risks, costs, and downtime. It integrates real-time analytics, advanced automation solutions, sophisticated control systems, and lifecycle services.

Puffer-Sweiven is a localized, single point of contact for sales, service, and applied engineering for Emerson Automation Solutions in the Texas Gulf Coast and Central Texas area with the capabilities to combine with other members in North America to leverage global reach and technologies. Puffer is an Emerson Impact Partner.

With access to the two units, Greentown Labs member companies can further explore easy-to-use, integrated-by-design DeltaV Distributed Control System. With the system, companies and members can better scale new technologies into pilot scale, optimize processes for high quality products, and implement a smart foundation for access to contextualized data. Global ROC is one company that is already utilizing the new resources at Greentown Labs.

“Our member Global ROC, which is developing a solution for cooling tower systems that reduces chemical consumption, saves water, and reduces energy costs, plans to use the system in two ways,” Global ROC CEO Ely Trujillo said to Greentown Labs via LinkedIn.

The startup will be able to create a control method that can be applied to future projects by using and comparing Global ROC’s products with the Delta V’s advanced function blocks. Trujilloalso plans to train team members to set up a Proportional Integral Derivative (PID) controller. The PID involves building a lab test box that connects to the DeltaV’s CHARM modules to control a process to a temperature by varying amperage through the DeltaV’s PID controller.

As part of the 3-year kickoff of the Texas Exchange for Energy and Climate Entrepreneurship (TEX-E), Greentown Labs also celebrated 87 Texas students from The University of Texas at Austin, Texas A&M University, University of Houston, Rice University, Prairie View A&M University, and the Massachusetts Institute of Technology have been accepted into this year's Fellowship. The students will gain access to hands-on experiences including internships, pitch competitions, entrepreneurship bootcamps, courses, and conferences geared to help the climate and energy-transition innovation field.

In March, Greentown Labs and Browning the Green Space were named the newest accelerator for the Advancing Climatetech and Clean Energy Leaders Program, or ACCEL. The seven selected startups will have a year-long curated curriculum, incubation at Greentown's two locations, and a non-dilutive $25,000 grant.

A research lab at the University of Houston has developed a new type of material for sodium-ion batteries that could make them more efficient and boost their energy performance.

Led by Pieremanuele Canepa, Robert Welch assistant professor of electrical and computer engineering at UH, the Canepa Research Laboratory is working on a new material called sodium vanadium phosphate, which improves sodium-ion battery performance by increasing the energy density. Energy density is the amount of energy stored per kilogram, and the new material can do so by more than 15 percent. With a higher energy density of 458 watt-hours per kilogram — compared to the 396 watt-hours per kilogram in older sodium-ion batteries — this material brings sodium technology closer to competing with lithium-ion batteries, according to the researchers.

The Canepa Lab used theoretical expertise and computational methods to discover new materials and molecules to help advance clean energy technologies. The team at UH worked with the research groups headed by French researchers Christian Masquelier and Laurence Croguennec from the Laboratoire de Reáctivité et de Chimie des Solides, which is a CNRS laboratory part of the Université de Picardie Jules Verne, in Amiens France, and the Institut de Chimie de la Matière Condensée de Bordeaux, Université de Bordeaux, Bordeaux, France for the experimental work on the project.

The researchers then created a battery prototype using the new materia sodium vanadium phosphate, which demonstrated energy storage improvements. The material is part of a group called “Na superionic conductors” or NaSICONs, which is made to let sodium ions move in and out of the battery during charging and discharging.

“The continuous voltage change is a key feature,” Canepa says in a news release. “It means the battery can perform more efficiently without compromising the electrode stability. That’s a game-changer for sodium-ion technology.”

The synthesis method used to create sodium vanadium phosphate may be applied to other materials with similar chemistries, which could create new opportunities for advanced energy storage. A paper of this work was published in the journal Nature Materials.

"Our goal is to find clean, sustainable solutions for energy storage," Canepa adds. "This material shows that sodium-ion batteries can meet the high-energy demands of modern technology while being cost-effective and environmentally friendly."
