Here are the most promising energy tech startups in the market today. Natalie Harms/InnovationMap

This week, 39 energy startup companies from all over the world pitched in Houston — and nine were recognized as being the most promising of the batch.

The Rice Alliance for Technology and Entrepreneurship returned its Offshore Technology Conference pitch event to its in-person capacity and host the annual event at the Ion Houston for the first time. The event featured three-minute pitches from the companies, and a select group of corporate and venture investors decided on the top nine to honor.

"We asked investors and corporates to look at the companies here today and help us determine the companies most promising — based on those that have an innovative technology that is solving a large problem, has customers willing to pay for it, and has the right team to build and grow their company," Brad Burke, managing director of the Rice Alliance says to the crowd at the event on May 3.

Here's which energy tech companies stood out to investors.

EarthEn

EarthEn, a Chandler, Arizona-based company, is a grid-scale energy storage solution. The technology can provide short-term — 6 to 8 hours — and long-term — over 100 hours — storage. The EarthEn pods provide a cheaper alternative and are built using 3D printing.

Echogen Power Systems

Based in Akron, Ohio, Echogen Power Systems has created a technology that captures heat that would otherwise be lost and converts it to a useable power source. The solution allows for any customer that operates at significant levels of heat to have a cost-effective energy option.

FuelX Innovation

Based in Aiken, South Carolina, FuelX Innovation is manufacturing solid-state hydrogen products and power systems, impacting mobile hydrogen fuel cell-powered applications. The company is focused on producing the lowest cost Alane, or aluminum hydride, for the fuel cell.

Lillianah Technologies

Lillianah Technologies, based in the Houston area in Spring, uses algae to remove carbon dioxide from the atmosphere. The company sells carbon offsets to corporations.

oPRO.ai

oPRO.ai — which is based in Los Altos, California — is providing its customers with deep learning optimization software for process and responsible operations for oil and gas, petrochemical, chemicals, and metal industries.

Proteum Energy

Phoenix, Arizona-based Proteum Energy provides its customers low-cost, clean hydrogen by reforming renewable ethanol into renewable hydrogen.

Sync Power Solutions

Embracing a clean sheet approach, Sync Power Solutions, based in Abilene, Texas, created a solution involving a redesign of electric motors and generators to increase energy efficiency, save on costs, and more.

Utility Global

Houston-based Utility Global is using high temperature electrolysis without the use of electricity to produce hydrogen from waste gases.

ZL Innovations

Based in Portland, Oregon, ZL Innovations is focused on eliminating greenhouse gas emissions from failed industrial valves. The company's solution is a magnetic actuation assembly that can be better sealed to prevent emissions.

MD Anderson launches $10M collaboration to advance personalized cancer treatment tech

fighting cancer

The University of Texas MD Anderson Cancer Center and Japan’s TOPPAN Holdings Inc. have announced a strategic collaboration to co-develop TOPPAN Holdings’ 3D cell culture, or organoid, technology known as invivoid.

The technology will be used as a tool for personalized cancer treatments and drug screening efforts, according to a release from MD Anderson. TOPPAN has committed $10 million over five years to advance the joint research activities.

“The strategic alliance with MD Anderson paves a promising path toward personalized cancer medicine," Hiroshi Asada, head of the Business Innovation Center at TOPPAN Holdings, said in a news release.

Invivoid is capable of establishing organoid models directly from patient biopsies or other tissues in a way that is faster and more efficient. Researchers may be able to test a variety of potential treatments in the laboratory to understand which approach may work best for the patient, if validated clinically.

“Organoids allow us to model the three-dimensional complexity of human cancers in the lab, thus allowing us to engineer a powerful translational engine—one that could not only predict how patients will respond to therapy before treatment begins but also could help to reimagine how we discover and validate next-generation therapies," Dr. Donna Hansel, division head of pathology and laboratory medicine at MD Anderson, added in the news release. “Through this collaboration, we hope to make meaningful progress in modeling cancer biology for therapeutic innovation.”

The collaboration will build upon preclinical research previously conducted by MD Anderson and TOPPAN. The organizations will work collaboratively to obtain College of American Pathologists (CAP) and Clinical Laboratory Improvement Amendments (CLIA) certifications for the technology, which demonstrate a commitment to high-quality patient care. Once the certifications are obtained, they plan to conduct observational clinical studies and then prospective clinical studies.

“We believe our proprietary invivoid 3D cell culture technology, by enabling the rapid establishment of organoid models directly from patient biopsies, has strong potential to help identify more effective treatment options and reduce the likelihood of unnecessary therapies,” Asada added in the release. “Through collaboration on CAP/CLIA certification and clinical validation, we aim to bring this innovation closer to real-world patient care and contribute meaningfully to the advancement of cancer medicine."
