Third Annual Energy Venture Day and Pitch Competition Announces Winners at CERAWeek

Published Mar 21, 2024 by Hailea Schultz

CERAWeek Pitch Competition 2024

More than 40 energy startups from across the globe participated in the third annual Energy Venture Day Pitch Competition, hosted by the Partnership’s Houston Energy Transition Initiative (HETI) alongside Rice Alliance for Technology & Entrepreneurship and TEX-E. 

The competition, held during S&P’s 2024 CERAWeek, was an opportunity for the Partnership to convene key energy industry members and investors to spotlight innovative energy transition startups. 

“This event showcases what Houston is all about,” said Bobby Tudor, HETI Chair. “If you have a promising technology with the potential to create real impact, Houston is the place where that idea reach scale. In this region, new companies can connect with our incumbent industry, solve mutual challenges, and deploy novel solutions.” 

Startups competed across five categories: carbon capture use and storage, energy storage, hydrogen solutions, TEX-E and people’s choice. The winners were selected by a panel of industry experts and investors, including Halliburton Labs, Mitsubishi Heavy Industries, Chevron Technology Ventures and more. Here are the winners: 


  • Ardent – Delaware-based startup that develops cost-effective and energy-efficient advanced membrane technologies to accelerate decarbonization across heavy industries like cement, steel and petrochemical. 

Energy Storage 

  • SunGreenH2 – Singapore-based startup that is cultivating high-performance electrolysers to significantly boost hydrogen production efficiency and reduce costs, aiming for affordable green hydrogen on a global scale. 

Hydrogen Solutions 

  • Thiozen – California-based spinout from MIT working to commercialize a process that can produce hydrogen from sour gas waste streams. 


  • Solidec – Houston-based spinout from Rice University that is developing a platform technology that captures carbon and generates chemicals without fossil fuels, using only air, water, and electricity. 

People's Choice

  • Decimetrix - Houston-based startup headquartered inside GreenTown labs that offers a comprehensive carbon footprint management solution.

Hydrogen Fuel Experiment to Take Off at IAH

George Bush Intercontinental Airport (IAH) has been chosen as one of the five North American locations where Airbus will study the feasibility of creating a hydrogen hub.   The European multinational aerospace corporation is partnering with the Center for Houston’s Future (CHF) and Houston Airport System to examine the viability of equipping airports with the infrastructure to support hydrogen fuel for aircraft. The analysis, expected to conclude in March 2025, will focus on identifying potential opportunities and barriers to hydrogen usage at airports, as well as defining the requirements for an ‘end-to-end' hydrogen supply chain, as Airbus works to achieve its goal of having hydrogen commercial aircraft operational and carrying passengers by 2035.  “Building airplanes which run on clean hydrogen may take some time, but we can begin today by looking at how we can use clean hydrogen in airport operations, such as ground equipment and public transportation so we can be ready for the future,” CHF CEO Brett Perlman said.  The airline industry is increasingly investing in sustainable aviation fuel (SAF), an alternative fuel made from non-petroleum feedstocks that reduces emissions from air transportation to reach net zero carbon goals.  According to the U.S. Department of Energy, aviation accounts for 2 percent of all carbon dioxide (CO2) emissions and 12 percent of all CO2 emissions from transportation worldwide. This collaborative effort can help accelerate SAF technology and adoption.  “As we continue to expand and modernize our facilities, participating in this sustainability study is crucial,” said Jim Szczesniak, Aviation Director for the City of Houston. “Continuing to build a sustainable airport system will ensure a healthy future for Houston, attract top talent and businesses, and demonstrate our commitment to being a responsible global citizen.”  The Airbus announcement follows the recent creation of the Sustainable Aviation Fuel Coalition, a nonprofit made up of key airlines, manufacturers and trade groups to advance the development of low-carbon fuels and decrease emissions in the industry. The organization will also advocate for federal policies that support the creation of a robust domestic market with lower prices and higher supply. Coalition members with a strong Houston presence include United Airlines, the Boeing Company and Sumitomo Corporation of Americas.  Other SAF developments include an agreement between United and Cemvita Corporation, a Houston-based cleantech startup focused on applying synthetic biology to enable a sustainable energy transition, to supply the airline with up to one billion gallons of sustainable aviation fuel from their first full-scale SAF plant over the next twenty years.   Learn how the Energy Capital of the World is leading the energy transition to a low-carbon, energy-abundant future.

BP Donates $200K to Houston Community College for EV Safety Training

Demonstrating its continued commitment to advancing the energy transition and bolstering the region’s workforce, BP donated $200,000 to Houston Community College (HCC) to fund an electrical vehicle safety and mechanic training course for City of Houston and Harris County employees. The initiative underscores the international company’s commitment to sustainability and aims to equip local technicians with the specialized skills needed for the future of transportation.  The program aims to train more than 250 fleet department employees this year by providing safety knowledge for handling EVs and advanced training on repairs and maintenance.  “We embrace Houston's role as the energy capital of the world and we continue to support the city and the county and their efforts to advance the energy transition,” Mark Crawford, Sr. Vice President of Diversity, Equity and Inclusion at bp, said during a check presentation at an HCC Board of Trustees meeting. “We are excited for the year ahead and many technicians who will depart HCC campus with a certificate in hand and new knowledge to utilize.”  Click to expand bp check presentation to HCC to fund EV safety training   In 2020, the City of Houston released its Climate Action Plan which included converting non-emergency, light-duty municipal vehicles to electric by 2030. Harris County has a similar goal to transition its fleet to electric vehicles.  HCC’s Northeast College President Michael Edwards applauded bp’s investment and commitment to strengthening communities, creating sustainable jobs and advancing the transition.   “bp America seeks to work with partners to develop initiatives for the area's most impacted by the energy transition and enable the workforce to gain the skills needed for future energy systems,” said Michael Edwards, PhD, President of HCC’s Northeast College Campus.    Earlier this year, bp launched its first U.S. EV charging station, bp Pulse, at the company’s Energy Corridor headquarters. The station, offering 24 high-speed EV charge points, is part of bp’s plan to invest $1 billion in EV charging infrastructure by 2030.  Learn more about Houston's energy industry.
