That's a wrap on Offshore Technology Conference, which took place at NRG Park from Monday, May 6, to Thursday, May 9. The 55th annual conference welcomed over 30,000 participants from 107 countries to discuss the evolving offshore energy sector.

"It was inspiring to see the global energy community come together to discuss and partner in solutions that will shape a sustainable future," Alex Martinez, chair of the OTC board, says in a news release. "As the world’s population continues to grow and require more energy, there is no other event that provides attendees with more diverse conversations focused on the latest developments needed to accelerate the global energy mix.”

With an estimated $3 billion impact on the local economy, the four-day event featured a 1,300-company showcase as well as over 50 sessions, including panels, fireside chats, and networking events. Many of these sessions included thought leadership from Houston professionals overseeing energy transition initiatives at their respective companies.

In fact, OTC returned its Energy Transition Pavilion for 2024 to highlight innovative solutions within energy transition, which included geothermal energy, rig electrification, and the role of AI and data analytics. Additionally, the event featured its Offshore Wind Thread across three days of discussion.

OTC honored two sets of honorees throughout the week too. Three Distinguished Achievement Award recipients were honored at a reception ahead of the official conference and nine young professionals were named as the 2024 Emerging Leaders cohort on May 7.

The organization has already committed to returning to Houston next year. OTC 2025 will take place May 5 to 8, again at NRG Center.

Houston-based Helix Earth Technologies has closed a $12 million Seed 2 funding round to scale manufacturing of its energy-efficient commercial HVAC add-on technology.

Veriten, a Houston-based energy investment firm, led the round. Rua Ventures, Carnrite Ventures, Skywriter LLC and Textbook Ventures also participated.

Helix Earth—which was founded based on NASA technology, spun out of Rice University and has been incubated at Greentown Labs—is developing high-efficiency retrofit dehumidification systems that aim to reduce the energy consumption of commercial HVAC units. The company reports that its technology can lead to "healthier indoor air, lower energy bills, reduced building maintenance, and more comfortable spaces for building owners and occupants."

"Building owners are dealing with rising energy costs, uncontrolled humidity, and aging infrastructure with no viable, cost-effective path forward. We are in the field today solving these problems for commercial customers, and this capital puts us on an aggressive path to scale,” Rawand Rasheed, Helix Earth co-founder and CEO, said in a news release.

“The strength of this round reinforces our team's conviction that we can transform innovation-starved sectors with transformational solutions that deliver order-of-magnitude improvements to owners and operators, for both their bottom line and the environment,” Rasheed added.

Maynard Holt, Veriten’s founder and CEO, said that the investment firm is tripling its investment in Helix Earth.

"The team has built breakthrough technology with real applicability across multiple industries,” Holt said in the release. “Their first product will have an immediate and measurable impact on our energy system, and they are already pursuing adjacent innovations to help heavy industries operate more efficiently and with less waste. This is a well-rounded team with a proven track record of strong execution and disciplined capital management.”

Helix Earth also closed a $5.6 million seed funding round in 2024, led by Veriten.

Last year, the company secured a $1.2 million Small Business Innovation Research (SBIR) Phase II grant and won in the Smart Cities, Transportation & Sustainability contest at the 2025 SXSW Pitch Showcase. Rasheed was also named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.
