For several years now, Matthew Costello has been navigating the maritime shipping industry looking for problems to solve for customers with his company, Voyager Portal.

Initially, that meant designing a software platform to enhance communications and organization of the many massive and intricate global shipments happening every day. Founded in 2018 by Costello and COO Bret Smart, Voyager Portal became a integral tool for the industry that helps users manage the full lifecycle of their voyages — from planning to delivery.

"The software landscape has changed tremendously in the maritime space. Back in 2018, we were one of a small handful of technology startups in this space," Costello, who serves as CEO of Voyager, says on the Houston Innovators Podcast. "Now that's changed. ... There's really a huge wave of innovation happening in maritime right now."

And, predictably, some of those waves are caused by new momentum within the energy transition.

"The energy transition has thrown up a lot of questions for everyone in the maritime industry," Costello says. "The regulations create a lot of questions around cost primarily. ... And that has created a huge number of opportunities for technology."

Fuel as a primary cost for the maritime industry. These cargo ships are traversing the world 24/7 and burning fuel at all times. Costello says there's an increased focus on the fuel process — "all with a goal of essentially reducing carbon intensity usage."

One of the ways to move the needle on reducing the carbon footprint of these ships is optimizing the time spent in port, and specifically the delays associated. Demurrage are charges associated with delays in loading and unloading cargo within maritime shipping, and Costello estimates that the total paid globally in demurrage fees is around $10 billion to $20 billion a year.

"These fees can be huge," Costello says. "What technology has really enabled with this problem of demurrage is helping companies drill down to the true root cause of what something is happening."

All this progress is thanks to the enhancement — and wider range of acceptance — of data analysis and artificial intelligence.

Costello, who says Voyager has been improving its profitability every quarter for the last year, has grown the business to around 40 employees in its headquarters of Houston and three remote offices in Brazil, London, and Singapore. The company's last round of funding was a series A in 2021. Costello says the next round, if needed, would be next year.

In the meantime, Voyager is laser focused on providing optimized, cost-saving, and sustainable solutions for its customers — around half of which are headquartered or have a significant presence in Houston. For Costello, that's all about putting the control back into the hands of his customers.

"If we think back to the real problems the industry faces, a lot of them are controlled by different groups and parties. The fact that a ship cannot get in and out of a port quickly is not necessarily a function of one party's issue — it's a multitude of issues, and there's no one factor," Costello says on the show. "To really make the whole process efficient end-to-end you need to provide the customer to access and options for different means of getting cargo from A to B — and you need to have a sense of control in that process."

UH lands $1M NSF grant to train future critical minerals workforce

workforce pipeline

The University of Houston has launched a $1 million initiative funded by the National Science Foundation to address the gap in the U.S. mineral industry and bring young experts to the field.

The program will bring UH and key industry partners together to expand workforce development and drive research that fuels innovation. It will be led by Xuqing "Jason" Wu, an associate professor of information science technology.

“The program aims to reshape public perception of the critical minerals industry, highlighting its role in energy, defense and advanced manufacturing,” Wu said in a news release. “Our program aims to showcase the industry’s true, high-tech nature.”

The project will sponsor 10 high school students and 10 community college students in Houston each year. It will include industry mentors and participation in a four-week training camp that features “immersive field-based learning experiences.”

“High school and community college students often lack exposure to career pathways in mining, geoscience, materials science and data science,” Wu added in the release. “This project is meant to ignite student interest and strengthen the U.S. workforce pipeline in the minerals industry by equipping students with technical skills, industry knowledge and career readiness.”

This interdisciplinary initiative will also work with co-principal investigators across fields at UH:

  • Jiajia Sun, Earth & Atmospheric Sciences
  • Yan Yao and Jiefu Chen, Electrical and Computer Engineering
  • Yueqin Huang, Information Science Technology

According to UH, minerals and rare earth elements have become “essential building blocks of modern life” and are integral components in technology and devices, roads, the energy industry and more.

Houston microgrid company names new CEO

new hire

Houston-based electric microgrid company Enchanted Rock has named a new CEO.

John Carrington has assumed the role after serving as Enchanted Rock's executive chairman since June, the company announced earlier this month.

Carrington most recently was CEO of Houston-based Stem, which offers AI-enabled software and services designed for setting up and operating clean energy facilities. He stepped down as Stem’s CEO in September 2024. Stem, which was founded in 2006 and went public under Carrington's leadership in 2021, was previously based in San Francisco.

Carrington has also held senior leadership roles at Miasolé, First Solar and GE.

Corey Amthor has served as acting CEO of Enchanted Rock since June. He succeeded Enchanted Rock founder Thomas McAndrew in the role, with McAndrew staying on with the company as a strategic advisor and board member. With the hiring of Carrington, Amthor has returned to his role as president. According to the company, Amthor and Carrington will "partner to drive the company’s next phase of growth."

“I’m proud to join a leadership team known for technical excellence and execution, and with our company-wide commitment to innovation, we are well positioned to navigate this moment of unprecedented demand and advance our mission alongside our customers nationwide,” Carrington said in the news release. “Enchanted Rock’s technology platform delivers resilient, clean and scalable ultra-low-emissions onsite power that solves some of the most urgent challenges facing our country today. I’m energized by the strong momentum and growing market demand for our solutions, and we remain committed to providing data centers and other critical sectors with the reliable power essential to their operations.”

This summer, Enchanted Rock also announced that Ian Blakely would reassume the role of CFO at the company. He previously served as chief strategy officer. Paul Froutan, Enchanted Rock's former CTO, was also named COO last year.
