Pipeline robotics: How this Houston startup is revolutionizing corrosion monitoring

After working for years in the downstream energy industry where safety and efficiency were top priorities, Dianna Liu thought there was a way technology could make a huge difference.

Despite loving her company and her job, she took a leap of faith to start a robotics company to create technology to more safely and efficiently monitor corrosion in pipelines. ARIX Technologies has developed software and hardware solutions for its customers with pipelines in downstream and beyond.

"Overall, this industry is an industry that really harps on doing things safely, doing things well, and having all the data to make really informed decisions," Liu says on the Houston Innovators Podcast. "Because these are huge companies with huge problems, it takes a lot of time to set up the right systems, adopt new things, and make changes."

But it's an industry Liu knows well, so she founded ARIX in 2017 and created a team of engineers to create the first iteration of the ARIX robot, which was at first made of wood, she says. Now, years later, the much-evolved robot moves up and down the exterior of the pipe, using its technology to scan the interior to evaluate corrosion. The technology works with ARIX's software to provide key data analysis.

With customers across the country and the world, ARIX has a strong foothold in downstream, but has garnered interest from other verticals as well — even working with NASA at one point, Liu says.

"Staying in downstream would be nice and safe for us, but we've been very lucky and have had customers in midstream, upstream, and even outside oil and gas and chemicals," she says. "We've gotten inquiries ranging from cosmetics plants to water or wastewater — essentially anything that's round or a pipe that can corrode, we can help with."

Liu, who goes into detail on the show about how critical establishing a positive company culture has been for ARIX, shares a bit about what it's been like growing her company in Houston.

"Houston being the Energy Capital of the World opens a lot of doors to both customers, investors, and employees in a way that's unparalleled. It is a great place to build a company because of that — you have all this expertise in this city and the surrounding areas that's hard to find elsewhere," she says. "Being such a hub — not only for energy, but in terms transportation — means it's easy for us to get to our customers from around the world."

Houston-based Occidental Petroleum is gearing up to start removing CO2 from the atmosphere at its $1.3 billion direct air capture (DAC) project in the Midland-Odessa area.

Vicki Hollub, president and CEO of Occidental, said during the company’s recent second-quarter earnings call that the Stratos project — being developed by carbon capture and sequestration subsidiary 1PointFive — is on track to begin capturing CO2 later this year.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos.

Carbon dioxide captured by Stratos will be stored underground or be used for enhanced oil recovery.

Oxy says Stratos is the world’s largest DAC facility. It’s designed to pull 500,000 metric tons of carbon dioxide from the air and either store it underground or use it for enhanced oil recovery. Enhanced oil recovery extracts oil from unproductive reservoirs.

Most of the carbon credits that’ll be generated by Stratos through 2030 have already been sold to organizations such as Airbus, AT&T, All Nippon Airways, Amazon, the Houston Astros, the Houston Texans, JPMorgan, Microsoft, Palo Alto Networks and TD Bank.

The infrastructure business of investment manager BlackRock has pumped $550 million into Stratos through a joint venture with 1PointFive.

As it gears up to kick off operations at Stratos, Occidental is also in talks with XRG, the energy investment arm of the United Arab Emirates-owned Abu Dhabi National Oil Co., to form a joint venture for the development of a DAC facility in South Texas. Occidental has been awarded up to $650 million from the U.S. Department of Energy to build the South Texas DAC hub.

The South Texas project, to be located on the storied King Ranch, will be close to industrial facilities and energy infrastructure along the Gulf Coast. Initially, the roughly 165-square-mile site is expected to capture 500,000 metric tons of carbon dioxide per year, with the potential to store up to 3 billion metric tons of CO2 per year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” Hollub said.
