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.

The event takes place at 9 am on Wednesday, March 3. Learn more.

Thursday — How Will the Energy Innovation Ecosystem Evolve?

Although the cleantech innovation ecosystem—research institutions, entrepreneurs, financiers, and support institutions—is diverse and productive, converting cleantech discoveries and research breakthroughs into commercially viable, transformative energy systems has proven difficult. With incumbent energy systems economically efficient and deeply entrenched, cleantech innovation faces a fundamental dilemma—the scale economies necessary to compete require a large customer base that does not yet exist. How is our clean energy innovation ecosystem equipped to be transformative? What needs to be strengthened? Is it profitable to focus on individual elements, or should we consider the system holistically, and reframe our expectations?

Featuring: Barbara Burger, vice president of innovation at Chevron and president at Chevron Technology Ventures

The event takes place at 7:30 am on Thursday, March 4. Learn more.

Friday — Cities: Managing crises & the future of energy

Houston is the capital of global energy and for the past four decades the home of CERAWeek. Mayor Sylvester Turner will share lessons from the city's experience with the pandemic, discuss leadership strategies during times of crisis, and explore Houston's evolving role in the new map of energy.

The event takes place at 8 am on Friday, March 5. Learn more.

How executive education retains your best employees + drives success

Investing in People

Hiring is tough, but retaining great people is even harder. Ask almost any manager what keeps them up at night, and the answer usually comes back to the same thing: How do we keep our best employees growing here instead of looking elsewhere?

One reliable approach has held up across industries. When people see their employer investing in their development, they’re more likely to stay, contribute, and imagine a future with the organization.

The data backs this up. Employees who take part in ongoing training are far less likely to leave, and the effect is especially strong for younger workers. One national survey found that 86% of millennials would stay with an employer that invests in their development. Companies that build a real learning culture see retention jump by 30-50%. The pattern is consistent: When people can learn and advance, they stay.

The ROI of executive education
Professional development signals value, but it also builds capability. When people have access to structured learning, they become better problem-solvers, more adaptable, and more confident leading through change.

That's the focus of Executive Education at Rice University's Jones Graduate School of Business. The portfolio is built for the realities of modern leadership: AI and digital transformation courses for teams navigating new technologies, and deeper programs in innovation and strategy for leaders sharpening long-term thinking.

“People, managers, professionals, and executives in all functional areas of business can benefit from this program,” notes Jing Zhou, Mary Gibbs Jones Professor of Management and Psychology at Rice. “We teach the fundamental principles of how to drive innovation and broaden the cognitive space.”

That perspective runs through every offering, from the Rice Advanced Management Program to the Leadership Accelerator and Leading Innovation. Each program gives participants practical tools to think strategically, work across teams and make meaningful change inside their organizations.

Building the leadership pipeline
Leadership development isn’t a perk anymore. It’s a strategic need for any organization that wants to grow and stay competitive.

Employers know this — nearly two-thirds say leadership training is essential to their success — yet employees still report feeling stalled. Reports find 74% of employees feel they aren’t reaching their potential because they lacked meaningful growth opportunities.

Rice Business designs its Executive Education programs to address that gap. The Rice Advanced Management Program, for example, supports leaders preparing for C-suite, board, or enterprise-level roles. Its format — two in-person modules separated by several weeks — gives participants space to test ideas at work, return with questions, and build on what they’ve learned. The structure fits demanding executive schedules while creating room for deeper reflection and richer peer connections.

Just as important, the program helps senior leaders align on strategy and culture. Participants develop a shared language and build stronger relationships, which translates into clearer decision-making, better collaboration, and less burnout across teams.

Houston’s advantage
Houston gives Rice Business Executive Education a distinctive edge. The city’s position in energy, healthcare, logistics, and innovation means participants are learning in the middle of a global business ecosystem. That proximity brings a mix of perspectives you don’t get in more siloed markets, and it pushes leaders to apply ideas to real-world problems in real time.

The expertise runs deep on campus, as well. Participants learn from faculty who are shaping conversations in their fields, not just teaching from a playbook. For many organizations, that outside perspective is a meaningful complement to in-house training — a chance to stretch thinking, challenge assumptions, and broaden leadership capacity.

Rice Business offers multiple paths into that experience, from open-enrollment programs like Leading Organizational Change, Executive Leadership for Women, or Driving Growth through AI and Digital Transformation to fully customized corporate partnerships. Across all formats, the focus is the same: education that is practical, relevant, and built for impact.

Investing in retention and results
When organizations make room for real development, the payoff shows up quickly: higher engagement, stronger leadership pipelines, and lower turnover. It also shapes the culture. People are more willing to take risks, ask better questions, and stay curious when they know learning is part of the job.

As Brent Smith, senior associate dean for Executive Education at Rice Business, explains, “There’s a layer of learning in leadership that’s about helping people adopt a leadership identity — to see themselves as the actual leader for their organization. That’s not an easy transition, but it’s the foundation of lasting success.”

For companies that want to build loyalty, deepen leadership capacity, and stay competitive in a fast-changing environment, investing in people isn’t optional. Rice Business Executive Education offers a clear path to do it well. Learn more here.
