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.
