Fourteen companies pitched at the Rice Alliance for Technology and Entrepreneurship's Energy Venture Day at the 2021 Offshore Technology Conference, and virtual attendees voted on the companies they think are the most promising.

The companies, which hailed from three countries, again pitched virtually. Last year's venture day was also hosted virtually. The event's judging panel usually names 10 of the most promising companies at the event, however, just like last year, Rice Alliance put the power into the people viewing the pitches online.

Here are the four most promising energy tech companies that pitched at the annual OTC event.

American Hydrogen

Based in Tulsa, Oklahoma, American Hydrogen offers a fully integrated, end-to-end implementation solutions for hydrogen generation, storage, and distribution facilities.

"With roots in traditional energy, the American Hydrogen management team consists of senior oil and gas professionals who have spend decades developing infrastructure in prominent energy hubs across the United States. Through this field experience our team can furnish reliable and proven execution for an emerging clean technology market," per the company's website.

Alabastron Technologies

Houston-based Alabastron Technologies has developed a sensor that can detect organic and inorganic deposition in pipelines before any actual deposits form.

"Our service is a real-time closed-loop sensing, measurement and control strategy that remotely monitors oil production and the tendency of flow-restricting-substances or depositions prior to actual deposition," reads the company's website.

Applied Bioplastics

Applied Bioplastics, based in Austin, is commercializing an alternative to plastic by combining it plant fiber — operating with a carbon footprint 30 percent smaller than traditional plastic.

"Our products reduce petroleum dependency, pollution, and habitat destruction. Through our supply chains, we support eco-friendly agriculture in developing countries," according to the website.

DataSeer

Houston-based DataSeer is a cloud-based software application uses artificial intelligence to automatically detect, label and extract information from engineering data. The technology improves its customer's quality control and quality assurance of data extraction at scale.

"DataSeer was built in close collaboration with users at some of the largest engineering firms in the world, who we are proud to call our customers," the website reads.

Tech giant Apple doubles down on Houston with new production facility

coming soon

Tech giant Apple announced that it will double the size of its Houston manufacturing footprint as it brings production of its Mac mini to the U.S. for the first time.

The company plans to begin production of its compact desktop computer at a new factory at Apple’s Houston manufacturing site later this year. The move is expected to create thousands of jobs in the Houston area, according to Apple.

Last year, the Cupertino, California-based company announced it would open a 250,000-square-foot factory to produce servers for its data centers in the Houston area. The facility was originally slated to open in 2026, but Apple reports it began production ahead of schedule in 2025.

The addition of the Mac mini operations at the site will bring the footprint to about 500,000 square feet, the Houston Chronicle reports. The New York Times previously reported that Taiwanese electronics manufacturer Foxconn would be involved in the Houston factory.

Apple also announced plans to open a 20,000-square-foot Advanced Manufacturing Center in Houston later this year. The project is currently under construction and will "provide hands-on training in advanced manufacturing techniques to students, supplier employees, and American businesses of all sizes," according to the announcement. Apple opened a similar Apple Manufacturing Academy in Detroit last year.

“Apple is deeply committed to the future of American manufacturing, and we’re proud to significantly expand our footprint in Houston with the production of Mac mini starting later this year,” Tim Cook, Apple’s CEO, said in the news release. “We began shipping advanced AI servers from Houston ahead of schedule, and we’re excited to accelerate that work even further.”

Apple's Houston expansion is part of a $600 billion commitment the company made to the U.S. in 2025.

Houston energy trailblazer Fervo taps into hottest reservoir to date

Heating Up

Things are heating up at Houston-based geothermal power company Fervo Energy.

Fervo recently drilled its hottest well so far at a new geothermal site in western Utah. Fewer than 11 days of drilling more than 11,000 feet deep at Project Blanford showed temperatures above 555 degrees Fahrenheit, which exceeds requirements for commercial viability. Fervo used proprietary AI-driven analytics for the test.

Hotter geothermal reservoirs produce more energy and improve what’s known as energy conversion efficiency, which is the ratio of useful energy output to total energy input.

“Fervo’s exploration strategy has always been underpinned by the seamless integration of cutting-edge data acquisition and advanced analytics,” Jack Norbeck, Fervo’s co-founder and chief technology officer, said in a news release. “This latest ultra-high temperature discovery highlights our team’s ability to detect and develop EGS sweet spots using AI-enhanced geophysical techniques.”

Fervo says an independent review confirms the site’s multigigawatt potential.

The company has increasingly tapped into hotter and hotter geothermal reservoirs, going from 365 degrees at Project Red to 400 degrees at Cape Station and now more than 555 degrees at Blanford.

The new site expands Fervo’s geologic footprint. The Blanford reservoir consists of sedimentary formations such as sandstones, claystones and carbonates, which can be drilled more easily and cost-effectively than more commonly targeted granite formations.

Fervo ranks among the top-funded startups in the Houston area. Since its founding in 2017, the company has raised about $1.5 billion. In January, Fervo filed for an IPO that would value the company at $2 billion to $3 billion, according to

Axios Pro.
