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."

Hazardous waste company with Houston presence to make $3B acquisition

big deal

Veolia, a Boston-based company with major operations in Texas, is purchasing hazardous-waste company Clean Earth from Enviri as part of a $3 billion deal.

Veolia is a private water operator, technology provider and hazardous waste and pollution treatment company that operates a large hazardous waste treatment and incineration facility in Port Arthur. Hazardous waste treatment is a growing sector as the clean energy, semiconductor manufacturing, healthcare and pharmaceutical industries generate high levels of waste that need to be handled safely.

Acquiring Clean Earth’s 82 facilities, which include 19 EPA-permitted sites, will expand Veolia’s reach into 10 new states and will position the company as the second-largest hazardous waste operator in the U.S., according to a news release. The deal is Veolia’s sixth and largest North American acquisition of 2025.

“(The acquisition) allows us to unlock the full value potential of our U.S. hazardous waste activities and to double our size on this critical, fast-growing sector, creating a No. 2 player,” Estelle Brachlianoff, CEO of Veolia, said in a news release. “We reinforce our global capacities in hazardous waste and further increase our international footprint.”

Veolia’s Port Arthur facility specializes in servicing generators with large-volume waste treatment requirements.

The transaction is expected to close mid-2026. Veolia hopes the increased exposure into industries such as retail and healthcare will help to offer a full range of environmental services across the U.S.

“This continued transformation of our portfolio enhances the growth profile and strength of our group, uniquely positioned to tackle the sustained demand for environmental security,” Brachlianoff added in the release.

Reliant partners to expand Texas virtual power plant and home battery use

energy incentives

Houston’s Reliant and San Francisco tech company GoodLeap are teaming up to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant (VPP) network in Texas.

Through the new partnership, eligible Reliant customers can either lease a battery or enter into a power purchase agreement with GoodLeap through its GoodGrid program, which incentivises users by offering monthly performance-based rewards for contributing stored power to the grid. Through the Reliant GoodLeap VPP Battery Program, customers will start earning $40 per month in rewards from GoodLeap.

“These incentives highlight our commitment to making homeowner battery adoption more accessible, effectively offsetting the cost of the battery and making the upgrade a no-cost addition to their homes,” Dan Lotano, COO at GoodLeap, said in a news release.“We’re proud to work with NRG to unlock the next frontier in distributed energy in Texas. This marks an important step in GoodLeap reaching our nationwide goal of 1.5 GW of managed distributed energy over the next five years.”

Other features of the program include power outage plans, with battery reserves set aside for outage events. The plan also intelligently manages the battery without homeowner interaction.

The partnership comes as Reliant’s parent company, NRG, continues to scale its VPP program. Last year, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 in an effort to help households manage and lower their energy costs.

“We started building our VPP with smart thermostats across Texas, and now this partnership with GoodLeap brings home battery storage into our platform,” Mark Parsons, senior vice president and head of Texas energy at NRG, said in a the release. “Each time we add new devices, we’re enabling Texans to unlock new value from their homes, earn rewards and help build a more resilient grid for everyone. This is about giving customers the opportunity to actively participate in the energy transition and receive tangible benefits for themselves and their communities.

How Corrolytics is tackling industrial corrosion and cutting emissions

now streaming

Corrosion is not something most people think about, but for Houston's industrial backbone pipelines, refineries, chemical plants, and water infrastructure, it is a silent and costly threat. Replacing damaged steel and overusing chemicals adds hundreds of millions of tons of carbon emissions every year. Despite the scale of the problem, corrosion detection has barely changed in decades.

In a recent episode of the Energy Tech Startups Podcast, Anwar Sadek, founder and CEO of Corrolytics, explained why the traditional approach is not working and how his team is delivering real-time visibility into one of the most overlooked challenges in the energy transition.

From Lab Insight to Industrial Breakthrough

Anwar began as a researcher studying how metals degrade and how microbes accelerate corrosion. He quickly noticed a major gap. Companies could detect the presence of microorganisms, but they could not tell whether those microbes were actually causing corrosion or how quickly the damage was happening. Most tests required shipping samples to a lab and waiting months for results, long after conditions inside the asset had changed.

That gap inspired Corrolytics' breakthrough. The company developed a portable, real-time electrochemical test that measures microbial corrosion activity directly from fluid samples. No invasive probes. No complex lab work. Just the immediate data operators can act on.

“It is like switching from film to digital photography,” Anwar says. “What used to take months now takes a couple of hours.”

Why Corrosion Matters in Houston's Energy Transition

Houston's energy transition is a blend of innovation and practicality. While the world builds new low-carbon systems, the region still depends on existing industrial infrastructure. Keeping those assets safe, efficient, and emission-conscious is essential.

This is where Corrolytics fits in. Every leak prevented, every pipeline protected, and every unnecessary gallon of biocide avoided reduces emissions and improves operational safety. The company is already seeing interest across oil and gas, petrochemicals, water and wastewater treatment, HVAC, industrial cooling, and biofuels. If fluids move through metal, microbial corrosion can occur, and Corrolytics can detect it.

Because microbes evolve quickly, slow testing methods simply cannot keep up. “By the time a company gets lab results, the environment has changed completely,” Anwar explains. “You cannot manage what you cannot measure.”

A Scientist Steps Into the CEO Role

Anwar did not plan to become a CEO. But through the National Science Foundation's ICorps program, he interviewed more than 300 industry stakeholders. Over 95 percent cited microbial corrosion as a major issue with no effective tool to address it. That validation pushed him to transform his research into a product.

Since then, Corrolytics has moved from prototype to real-world pilots in Brazil and Houston, with early partners already using the technology and some preparing to invest. Along the way, Anwar learned to lead teams, speak the language of industry, and guide the company through challenges. “When things go wrong, and they do, it is the CEO's job to steady the team,” he says.

Why Houston

Relocating to Houston accelerated everything. Customers, partners, advisors, and manufacturing talent are all here. For industrial and energy tech startups, Houston offers an ecosystem built for scale.

What's Next

Corrolytics is preparing for broader pilots, commercial partnerships, and team growth as it continues its fundraising efforts. For anyone focused on asset integrity, emissions reduction, or industrial innovation, this is a company to watch.
