From virtual to reality: This Houston extended reality CEO weighs in on energy transition applications

Q&A

Founded in 2023, MadXR is a Houston-based Extended Reality startup. The innovative company specializes in safety training experiences for the energy sector and beyond. From pre-built virtual reality training modules to custom developed, end-to-end XR solutions, MadXR creates interactive, lifelike virtual reality and augmented reality experiences that allow trainees to practice safety procedures in a controlled environment.

Houston Energy Transition Initiative recently connected with Miranda Palmisano, CEO of MadXR, to discuss the applications and benefits of XR—and how it can help energy companies reduce HSE risk and carbon intensity like never before.

HETI: You were at Chevron for nearly 10 years before MadXR. How did your experiences at Chevron shape your approach to starting and running your own company?

Miranda Palmisano: Prior to founding MadXR, I held many different roles at Chevron across upstream and downstream. As the Connected Worker Product Manager, I drove digital acceleration for our global field and maintenance teams in refineries, terminals, and manufacturing sites, elevating efficiency and safety. During that time, I began exploring the value case of VR across Chevron.

I formed the Extended Reality Team and shortly became the Extended Reality Product Manager. Our team began using VR to conduct safety training within a virtual environment. It allowed us to train Chevron’s workforce safer and more efficiently by providing hands-on experience without the risk of real-world errors.

HETI: What inspired you to start your own company?

MP: Extended reality is an exciting new technology, and I quickly discovered the growing need for flexible, cost-effective XR content development in relation to life-saving-action training, such as confined-space entry, lockout/tagout procedures, and working from heights. I believe that affordable and high-quality XR experiences should be accessible to all companies, regardless of budget. That’s why MadXR has transparent pricing options that range from pre-built VR training modules to turnkey teams—and we empower our customers to take full ownership of their content and assets.

HETI: How has being based in Houston helped MadXR?

MP: The network in Houston is unmatched. In the energy capital of the world, it’s much easier to access the companies we’re targeting and hire the talent we need to grow. Innovation hubs like Houston’s Ion District have given us the resources and opportunities to connect with a vast number of forward-thinking businesses.

HETI: Do you believe XR will be instrumental in helping companies reach low carbon or net zero goals?

MP: XR is poised to revolutionize the energy industry, offering unprecedented opportunities for efficiency, engagement, and environmental sustainability. Imagine donning a headset and virtually navigating a facility halfway across the globe in real-time, or preparing your entire team with comprehensive virtual training before they physically enter a site. These scenarios highlight XR’s potential to enhance operational efficiency and employee engagement significantly. Beyond the immediate benefits, XR also plays a crucial role in reducing carbon emissions by eliminating the need for unnecessary travel. This technology isn’t just about improving current processes; it’s about reimagining the future of energy industry operations in a more sustainable, efficient, and engaging way.

HETI: MadXR will be celebrating its first anniversary in April. Can you tell us more about your vision for the future and what you’re focused on in 2024?

MP: In 2023, we were focused on ramping up and generating awareness. This year, we’re dedicated to expanding our reach and impact. We plan to incorporate AI into our learning modules and XR development to make them even more informational and interactive.

While our primary focus is on energy, we’re exploring how we can extend XR training to other industries, including automotive, healthcare, and pharmaceuticals.

Gold H2 harvests clean hydrogen from depleted California reservoirs in first field trial

breakthrough trial

Houston climatech company Gold H2 completed its first field trial that demonstrates subsurface bio-stimulated hydrogen production, which leverages microbiology and existing infrastructure to produce clean hydrogen.

Gold H2 is a spinoff of another Houston biotech company, Cemvita.

“When we compare our tech to the rest of the stack, I think we blow the competition out of the water," Prabhdeep Singh Sekhon, CEO of Gold H2 Sekhon previously told Energy Capital.

The project represented the first-of-its-kind application of Gold H2’s proprietary biotechnology, which generates hydrogen from depleted oil reservoirs, eliminating the need for new drilling, electrolysis or energy-intensive surface facilities. The Woodlands-based ChampionX LLC served as the oilfield services provider, and the trial was conducted in an oilfield in California’s San Joaquin Basin.

According to the company, Gold H2’s technology could yield up to 250 billion kilograms of low-carbon hydrogen, which is estimated to provide enough clean power to Los Angeles for over 50 years and avoid roughly 1 billion metric tons of CO2 equivalent.

“This field trial is tangible proof. We’ve taken a climate liability and turned it into a scalable, low-cost hydrogen solution,” Sekhon said in a news release. “It’s a new blueprint for decarbonization, built for speed, affordability, and global impact.”

Highlights of the trial include:

  • First-ever demonstration of biologically stimulated hydrogen generation at commercial field scale with unprecedented results of 40 percent H2 in the gas stream.
  • Demonstrated how end-of-life oilfield liabilities can be repurposed into hydrogen-producing assets.
  • The trial achieved 400,000 ppm of hydrogen in produced gases, which, according to the company,y is an “unprecedented concentration for a huff-and-puff style operation and a strong indicator of just how robust the process can perform under real-world conditions.”
  • The field trial marked readiness for commercial deployment with targeted hydrogen production costs below $0.50/kg.

“This breakthrough isn’t just a step forward, it’s a leap toward climate impact at scale,” Jillian Evanko, CEO and president at Chart Industries Inc., Gold H2 investor and advisor, added in the release. “By turning depleted oil fields into clean hydrogen generators, Gold H2 has provided a roadmap to produce low-cost, low-carbon energy using the very infrastructure that powered the last century. This changes the game for how the world can decarbonize heavy industry, power grids, and economies, faster and more affordably than we ever thought possible.”

Rice University spinout lands $500K NSF grant to boost chip sustainability

cooler computing

HEXAspec, a spinout from Rice University's Liu Idea Lab for Innovation and Entrepreneurship, was recently awarded a $500,000 National Science Foundation Partnership for Innovation grant.

The team says it will use the funding to continue enhancing semiconductor chips’ thermal conductivity to boost computing power. According to a release from Rice, HEXAspec has developed breakthrough inorganic fillers that allow graphic processing units (GPUs) to use less water and electricity and generate less heat.

The technology has major implications for the future of computing with AI sustainably.

“With the huge scale of investment in new computing infrastructure, the problem of managing the heat produced by these GPUs and semiconductors has grown exponentially. We’re excited to use this award to further our material to meet the needs of existing and emerging industry partners and unlock a new era of computing,” HEXAspec co-founder Tianshu Zhai said in the release.

HEXAspec was founded by Zhai and Chen-Yang Lin, who both participated in the Rice Innovation Fellows program. A third co-founder, Jing Zhang, also worked as a postdoctoral researcher and a research scientist at Rice, according to HEXAspec's website.

The HEXASpec team won the Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge in 2024. More recently, it also won this year's Energy Venture Day and Pitch Competition during CERAWeek in the TEX-E student track, taking home $25,000.

"The grant from the NSF is a game-changer, accelerating the path to market for this transformative technology," Kyle Judah, executive director of Lilie, added in the release.
