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.

Tech giant Apple opens Advanced Manufacturing Center at massive Houston facility

up and running

Cupertino, California-based Apple Inc. unveiled its Advanced Manufacturing Center in the Houston area last week, marking the completion of the second of three facilities the tech giant plans to launch in the city by the end of this year.

The 20,000-square-foot training center will welcome small- and medium-sized businesses for free training and educational sessions to "help accelerate smart manufacturing across America," according to a release from Apple. Apple opened a similar Apple Manufacturing Academy in Detroit last year.

The AMC is part of Apple's 500,000-square-foot site in northwest Harris County. It also features a massive manufacturing site for Apple’s advanced AI servers and Mac mini. The facility was originally slated to open in 2026, but Apple began producing its advanced AI servers ahead of schedule in 2025.

The company said it plans to begin manufacturing its Mac mini at the site this year. The move will bring production of the compact desktop computer to the U.S. for the first time.

“In less than nine months, we have invested hundreds of millions of dollars into this Houston facility. We stood up a factory, started production, and shipped the first advanced AI servers off the line. Today, we’re thrilled to open our new Advanced Manufacturing Center, a place where businesses, workers, and students can learn the same innovative processes that we use to make Apple’s most groundbreaking products. And we’re pleased to begin Mac mini production later this year,” Tim Cook, Apple’s CEO, said in the news release. “We believe in American workers and American ingenuity, and we are moving at an incredible pace because we want to build more than great products. We want to build the future of American manufacturing.”

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

The company originally announced plans in February 2025 to open a 250,000-square-foot Houston factory, but doubled the facility's planned size about a year later. Apple has reported that the factory will employ thousands of workers.

“Houston is grateful to Apple for this significant investment in our city. The Advanced Manufacturing Center will create local jobs and will continue improving the quality of life of Houston residents," Houston Mayor John Whitmire added in the release. "The AMC also recognizes our city as a growing technology hub and solidifies Houston’s leadership in the manufacturing sector of the United States.”

The opening comes on the heels of New Jersey-based pharmaceutical giant Bristol Myers Squibb Co. officially naming Houston home of its new $2.3 billion, state-of-the-art manufacturing site. Read more here.

$5B MD Anderson-anchored Austin medical center to break ground this fall

moving forward

Construction on the $1 billion first phase of the AI-native University of Texas Dell Medical Center in Austin—which will feature a hospital operated by Houston’s UT MD Anderson Cancer Center—is set to start this fall.

The UT System Board of Regents approved funding for first-phase construction on Aug. 12.

The medical center—now expected to cost $5 billion, up from the initial $2.9 billion estimate—will span about 2.5 million square feet. It will include 300 to 500 patient beds, outpatient facilities, an emergency department and specialized care for cancer patients.

MD Anderson will bring its world-renowned oncology programs to the center’s integrated health care model, Dr. Claudia Lucchinetti, senior vice president of medical affairs at UT Austin and dean of the university’s Dell Medical School, tells Health Leaders.

Earlier this year, Austin tech billionaire Michael Dell and his wife, Susan, pledged $750 million for development of the medical center. The medical center, scheduled for completion in December 2030, will be a cornerstone of the new 300-acre UT Dell Campus for Advanced Research, a medical education and research hub.

“Through this new campus and medical center, Texas will lead America in health care innovation,” Gov. Greg Abbott said when the research campus was announced in April. “The next generation of medical breakthroughs will take place in Central Texas.”

The medical center will fold AI tools and other technology into the infrastructure, rather than having them added after it’s built. Among other capabilities, the technology will monitor real-time medical data, automate data entry, and help health care professionals quickly predict and identify risks to patients, according to Health Leaders.

“We are not just building a new medical center,” Lucchinetti says. “We are building a fundamentally new model of health. It’s not just a new facility. It’s not just a new collaboration. It is a convergence of capabilities that rarely come together at the same time.”
