This week, energy startups pitched virtually for venture capitalists — as well as over 1,000 attendees — as a part of Rice Alliance for Technology and Entrepreneurship's 18th annual Energy and Clean Tech Venture Forum.

At the close of the three-day event, Rice Alliance announced its 10 most-promising energy tech companies. Here's which companies stood out from the rest.

W7energy

Based in Delaware, W7energy has created a zero-emission fuel cell electric vehicle technology supported by PiperION polymers. The startup's founders aim to provide a more reliable green energy that is 33 percent cheaper to make.

"With ion exchange polymer, we can achieve high ionic conductivity while maintaining mechanical strength," the company's website reads. "Because of the platform nature of the chemistry, the chemical and physical properties of the polymer membranes can be tuned to the desired application."

Modumetal

Modumetal, which has its HQ in Washington and an office locally as well, is a nanotechnology company focused on improving industrial materials. The company was founded in 2006 by Christina Lomasney and John Whitaker and developed a patented electrochemical process to produce nanolaminated metal alloys, according to Modumetal's website.

Tri-D Dynamics

San Francisco-based Tri-D Dynamics has developed a suite of smart metal products. The company's Bytepipe product claims to be the world's first smart casing that can collect key information — such as leak detection, temperatures, and diagnostic indicators — from underground and deliver it to workers.

SeekOps

A drone company based in Austin, SeekOps can quickly retrieve and deliver emissions data for its clients with its advance sensor technology. The company, founded in 2017, uses its drone and sensor pairing can help reduce emissions at a low cost.

Akselos

Switzerland-based Akselos has been using digital twin technology since its founding in 2012 to help energy companies analyze their optimization within their infrastructure.

Osperity

Osperity, based in Houston's Galleria area, is a software company that uses artificial intelligence to analyze and monitor industrial operations to translate the observations into strategic intelligence. The technology allows for cost-effective remote monitoring for its clients.

DroneDeploy

DroneDeploy — based in San Francisco and founded in 2013 — has raised over $92 million (according to Crunchbase) for its cloud-based drone mapping and analytics platform. According to the website, DroneDeploy has over 5,000 clients worldwide across oil and gas, construction, and other industries.

HEBI Robotics

Pittsburgh-based HEBI Robotics gives its clients the tools to build custom robotics. Founded 2014, HEBI has clients — such as NASA, Siemens, Ericsson — across industries.

CarbonFree Chemicals

CarbonFree Chemicals, based in San Antonio and founded in 2016, has created a technology to turn carbon emissions to useable solid carbonates.

SensorUp

Canadian Internet of Things company, SensorUp Inc. is a location intelligence platform founded in 2011. The technology specializes in real-time analysis of industrial operations.

"Whether you are working with legacy systems or new sensors, we provide an innovative platform that brings your IoT together for automated operations and processes," the company's website reads.

Houston team develops low-cost device to treat infants with life-threatening birth defect

infant innovation

A team of engineers and pediatric surgeons led by Rice University’s Rice360 Institute for Global Health Technologies has developed a cost-effective treatment for infants born with gastroschisis, a congenital condition in which intestines and other organs are developed outside of the body.

The condition can be life-threatening in economically disadvantaged regions without access to equipment.

The Rice-developed device, known as SimpleSilo, is “simple, low-cost and locally manufacturable,” according to the university. It consists of a saline bag, oxygen tubing and a commercially available heat sealer, while mimicking the function of commercial silo bags, which are used in high-income countries to protect exposed organs and gently return them into the abdominal cavity gradually.

Generally, a single-use bag can cost between $200 and $300. The alternatives that exist lack structure and require surgical sewing. This is where the SimpleSilo comes in.

“We focused on keeping the design as simple and functional as possible, while still being affordable,” Vanshika Jhonsa said in a news release. “Our hope is that health care providers around the world can adapt the SimpleSilo to their local supplies and specific needs.”

The study was published in the Journal of Pediatric Surgery, and Jhonsa, its first author, also won the 2023 American Pediatric Surgical Association Innovation Award for the project. She is a recent Rice alumna and is currently a medical student at UTHealth Houston.

Bindi Naik-Mathuria, a pediatric surgeon at UTMB Health, served as the corresponding author of the study. Rice undergraduates Shreya Jindal and Shriya Shah, along with Mary Seifu Tirfie, a current Rice360 Global Health Fellow, also worked on the project.

In laboratory tests, the device demonstrated a fluid leakage rate of just 0.02 milliliters per hour, which is comparable to commercial silo bags, and it withstood repeated disinfection while maintaining its structure. In a simulated in vitro test using cow intestines and a mock abdominal wall, SimpleSilo achieved a 50 percent reduction of the intestines into the simulated cavity over three days, also matching the performance of commercial silo bags. The team plans to conduct a formal clinical trial in East Africa.

“Gastroschisis has one of the biggest survival gaps from high-resource settings to low-resource settings, but it doesn’t have to be this way,” Meaghan Bond, lecturer and senior design engineer at Rice360, added in the news release. “We believe the SimpleSilo can help close the survival gap by making treatment accessible and affordable, even in resource-limited settings.”

Texas among 5 hardest working states and more innovation news to know

Trending News

Editor's note: As we look back at the top Houston innovation news for the first half of September, reports show that Texas is one of the hardest working states, while local startup activity has slowed down. Plus, exciting medical innovation advancements. Here are the most-read InnovationMap stories from September 1-14.

Oxy's $1.3B Texas carbon capture facility on track to​ launch this year

gearing up

Houston-based Occidental Petroleum is gearing up to start removing CO2 from the atmosphere at its $1.3 billion direct air capture (DAC) project in the Midland-Odessa area.

Vicki Hollub, president and CEO of Occidental, said during the company’s recent second-quarter earnings call that the Stratos project — being developed by carbon capture and sequestration subsidiary 1PointFive — is on track to begin capturing CO2 later this year.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos.

Carbon dioxide captured by Stratos will be stored underground or be used for enhanced oil recovery.

Oxy says Stratos is the world’s largest DAC facility. It’s designed to pull 500,000 metric tons of carbon dioxide from the air and either store it underground or use it for enhanced oil recovery. Enhanced oil recovery extracts oil from unproductive reservoirs.

Most of the carbon credits that’ll be generated by Stratos through 2030 have already been sold to organizations such as Airbus, AT&T, All Nippon Airways, Amazon, the Houston Astros, the Houston Texans, JPMorgan, Microsoft, Palo Alto Networks and TD Bank.

The infrastructure business of investment manager BlackRock has pumped $550 million into Stratos through a joint venture with 1PointFive.

As it gears up to kick off operations at Stratos, Occidental is also in talks with XRG, the energy investment arm of the United Arab Emirates-owned Abu Dhabi National Oil Co., to form a joint venture for the development of a DAC facility in South Texas. Occidental has been awarded up to $650 million from the U.S. Department of Energy to build the South Texas DAC hub.

The South Texas project, to be located on the storied King Ranch, will be close to industrial facilities and energy infrastructure along the Gulf Coast. Initially, the roughly 165-square-mile site is expected to capture 500,000 metric tons of carbon dioxide per year, with the potential to store up to 3 billion metric tons of CO2 per year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” Hollub said.
