Wondering what energy tech companies you should keep an eye on? Wonder no more.

As a part of 2021 CERAWeek by IHS Markit, the Rice Alliance for Technology and Entrepreneurship hosted a virtual pitch competition today featuring 20 companies in four sessions. Each entrepreneur had four minutes to pitch, and then a few more to take questions from industry experts.

"Of the companies here today, we've intentionally selected a diverse group," says Brad Burke, managing director of the Rice Alliance at the start of the event. "They range from companies looking for their seed funding to companies that have raised $20 million or more."

The following companies pitched at the event: Acoustic Wells, ALLY ENERGY, Bluefield Technologies, Cemvita Factory, Connectus Global, Damorphe, Ovopod Ltd., DrillDocs, GreenFire Energy, inerG, Locus Bio-Energy Solutions, Nesh, Pythias Analytics, REVOLUTION Turbine Technologies, Revterra, ROCSOLE, Senslytics, Subsea Micropiles, Syzygy Plasmonics, Transitional Energy, and Universal Subsea.

At the end of each session, attendees voted via Zoom poll on which startup had the most potential. According to the event attendees, the most promising energy tech companies are:

REVOLUTION Turbine Technologies

Asheville, North Carolina-based REVOLUTION Turbine Technologies, an inaugural Greentown Houston member company, is working to "put a green spin on power." The company's micro-Expansion Turbine System produces green power for digital oilfield and pipeline initiatives through the recovery of excess natural gas pressure.

"RTT's technology provides a scalable, clean energy source to reliably power digital oilfield and pipeline initiatives at a significantly low operating cost," says Christopher Bean, founder and CEO, in his presentation. "Never has it been more important to make production and pipeline operations greener, safer, and efficient."

Connectus Global

Connectus Global, based in Calgary, provides custom technology solutions that can increase productivity, profits, and competitiveness. Connectus' Real-Time Location System, or RTLS, uses Ultra-Wide Band for communication and triangulation while hosting a Radio Frequency Identification Device, which come in the form of badges, tags, and receivers.

"In our first year, we received $800,000 in revenue and are on track to hit our numbers — $3.6 million — at the end of this fiscal year," says Mike Anderson, CEO of the company, in his presentation." We have a global white labeling agreement with Honeywell and we make up about 75 percent of their digitized workforce management portfolio."

The company's U.S. office is located in Houston.

DrillDocs

Houston-based DrillDocs has created an automated drilling cuttings characterization service, called CleanSight, that supports an operator's understanding of their wellbore's state of stability and cleanness in real time.

"We're taking computer vision to the drilling rig," says Calvin Holt, CEO and co-founder at DrillDocs, in his presentation. "Now for the first time, drilling and geomechanics teams will have unique, real-time data to ascertain the well's condition."

Revterra

Revterra, a Houston-based company and inaugural Greentown Houston member company, is creating a flywheel energy storage system for long-duration grid-scale applications.

"For those of us in Texas, the power outages we experienced a couple weeks ago are a stark reminder that the stability and the resiliency of our electric grid should be a top priority as we transition to low-emission power sources," says Ben Jawdat, founder and CEO at Revterra, in his presentation. "Energy storage is a critical element in both grid stability and enabling our transition to sustainable energy."

5 can't-miss innovation events at CERAWeek featuring Houston speakers

where to be online

While usually hundreds of energy experts, C-level executives, diplomats, members of royal families, and more descend upon Houston for the the annual CERAWeek by IHS Markit conference, this year will be a little different. Canceled last year due to COVID-19, CERAWeek is returning — completely virtually.

The Agora track is back and focused on innovation within the energy sector. The Agora track's events — thought-provoking panels, intimate pods, and corporate-hosted "houses" — can be accessed through a virtual atrium.

Undoubtedly, many of the panels will have Houston representatives considering Houston's dominance in the industry, but here are five innovation-focused events you can't miss during CERAWeek that feature Houstonians.

Monday — New Horizons for Energy & Climate Research

The COVID-19 pandemic has made vivid and real the risks of an uncontrolled virus. Risks posed by climate change are also becoming more palpable every day. At the forefront of understanding these risks, universities are developing solutions by connecting science, engineering, business, and public policy disciplines. Along with industry and governments, universities are critical to developing affordable and sustainable solutions to meet the world's energy needs and achieve net-zero emission goals. Can the dual challenge of more energy and lower emissions be met? What is some of the most promising energy and climate research at universities? Beyond research, what are the roles and responsibilities of universities in the energy transition?

Featuring: Kenneth B. Medlock, III, James A. Baker, III, and Susan G. Baker Fellow In Energy And Resource Economics, Baker Institute and Senior Director, Center For Energy Studies at Rice University

Catch the panel at 1 pm on Monday, March 1. Learn more.

Tuesday — Conversations in Cleantech: Powering the energy transition

With renewables investment outperforming oil and gas investment for the first time ever in the middle of a pandemic, 2020 was a tipping point in the Energy Transition. Low oil prices intensified energy majors' attention on diversification and expansion into mature and emerging clean technologies such as battery storage, low-carbon hydrogen, and carbon removal technologies. Yet, the magnitude of the Energy Transition challenge requires an acceleration of strategic decisions on the technologies needed to make it happen, policy frameworks to promote public-private partnerships, and innovative investment schemes.

Three Cleantech leaders share their challenges, successes, and lessons learned at the forefront of the Energy Transition. What is their vision and strategy to accelerate lowering emissions and confronting climate change? Can companies develop clear strategies for cleantech investments that balance sustainability goals and corporate returns? What is the value of increasing leadership diversity for energy corporations? Can the Energy Transition be truly transformational without an inclusive workforce and a diverse leadership?

Featuring: Emily Reichert, CEO of Greentown Labs, which is opening a location in Houston this year.

The event takes place at 11:30 am on Tuesday, March 2. Learn more.

Wednesday — Rice Alliance Venture Day at CERAWeek

The Rice Alliance for Technology and Entrepreneurship pitch event will showcase 20 technology companies with new solutions for the energy industry. Each presentation will be followed by questions from a panel of industry experts.

Presenting Companies: Acoustic Wells, ALLY ENERGY, Bluefield Technologies, Cemvita Factory, Connectus Global, Damorphe, Ovopod Ltd., DrillDocs, GreenFire Energy, inerG, Locus Bio-Energy Solutions, Nesh, Pythias Analytics, REVOLUTION Turbine Technologies, Revterra, ROCSOLE, Senslytics, Subsea Micropiles, Syzygy Plasmonics, Transitional Energy, and Universal Subsea.

Houston universities climb the ranks on annual list of most patents issued

top 100

The University of Houston and Rice University have claimed spots on the National Academy of Inventor's Top 100 U.S. Universities Granted Utility Patents.

The list is based on data obtained from the U.S. Patent and Trademark Office and ranks U.S. academic institutions that are advancing innovation by the number of utility patents issued in the prior year.

Utility patents are among the world’s most valuable assets because they give inventors exclusive commercial rights to produce and use their technology. The universities ranked on the list collectively hold nearly 6,500 patents.

“In the ever-evolving innovation landscape, it is imperative that the U.S. is remaining competitive and at the forefront of today’s emerging research and technologies,” Paul R. Sanberg, president of the NAI, said in a news release. “Ensuring the security of intellectual property through patenting is a crucial component to this and allows those innovations to be effectively moved to market, where they can create valuable societal and economic impact. The Top 100 U.S. list celebrates U.S. universities and their inventive staff and faculty for their dedication in ensuring their innovations and IP are protected.”

The University of Houston System came in at No. 62 with 34 patents, and Rice University claimed the No. 68 spot with 30 patents.

Both universities climbed up the rankings this year. Last year, UH was ranked No. 63 with 27 patents. Rice climbed an impressive 26 spots this year, after ranking No. 94 with 14 patents issued in 2023.

“Granted U.S. utility patents can tremendously help in commercializing the technologies covered by such patents by attracting industry investment and commercial partners on a global level,” Neha Malik, assistant director for intellectual property management in Rice's Office of Technology Transfer, said in a release. “Advancing in this list memorializes Rice’s commitment to support research programs of Rice faculty by generating a path for the university to bring its research to the marketplace.”

Other Texas universities on the list include:

  • No. 3 University of Texas System (234 patents)
  • No. 35 The Texas A&M System (61 patents)
  • No. 73 Texas Tech University System (25 patents)
  • No. 80 Baylor University (20 patents)

The University of California (540 patents) claimed the No. 1 spot again this year, followed by the Massachusetts Institute of Technology (295 patents), which also placed second for 2024.

First large-scale affordable housing project of 3D-printed homes rises in Houston

Building Blocks

What’s being promoted as the world’s first large-scale affordable housing development built using 3D technology is taking shape in Houston.

Houston-based 3D construction company HiveASMBLD has teamed up with Houston-based Cole Klein Builders and the City of Houston on the Zuri Gardens project. Located near Hobby Airport on Martindale Road, the first 3D-printed home at Zuri Gardens is set to be completed in October.

“Zuri Gardens was born from the frustration of watching hardworking families get priced out of safe, resilient housing. We knew there had to be a better way — and with this project, we’re proving that there is,” says Vanessa Cole, co-founder of Cole Klein Builders.

“By combining visionary design, advanced construction technology, and powerful partnerships, we’re building more than just homes — we’re creating a blueprint for the future of equitable homeownership in Houston and beyond.”

The development is being created for households earning up to 120 percent of the median income in the Houston metro area. For a four-member household in the Houston area, the 120 percent limit in 2025 is $121,300, as set by the U.S. Department of Housing and Urban Development (HUD).

The 13-acre Zuri Gardens development will feature 80 energy-efficient homes averaging 1,360 square feet. Prices will be in the mid to high $200s. The homes will qualify for up to $125,000 in down payment assistance from the City of Houston.

HiveASMBLD will print two different home designs, each with two-bedroom and two-and-a-half bathroom configurations, along with an office/flex space and a covered patio.

“The community we envision for Zuri Gardens is modern, safe, and one that residents will be proud to call home. When completed using HiveASMBLD’s innovative technology, this 3D-printed multifamily community will exemplify the future of residential affordable living,” says Timothy Lankau, founder and co-CEO of HiveASMBLD.

Developments like Zuri Gardens are popping up around the country.

“3D-printed homes are revolutionizing the construction industry by making home builds faster, cheaper, and more sustainable,” according to The Zebra, an Austin-based insurance marketplace. “In less than 24 hours, 3D printers can print the foundation and walls for a small home at a fraction of the cost of typical construction.”

U.S. News & World Report explains that unlike a traditional home, a 3D-printed home is printed in place, “just like you’d print a knickknack on your home 3D printer. Layer by layer, proprietary concrete blends are used to build the wall systems of the home in any type of design that a builder can imagine.”

Texas is home to several trailblazing 3D-printed projects.

In the U.S., the first 3D-printed home was built in 2018 in Austin, and the first 3D-printed multistory home was completed in 2023 in Harris County’s Spring Branch neighborhood. Meanwhile, the world’s largest neighborhood of 3D-printed homes is located in the Austin suburb of Georgetown.

Grand View Research predicts the global market for 3D-printed construction will approach $4.2 billion by 2030.
