Several years ago, Kelsey Hultberg decided to make a pivot. Looking for a role with career growth opportunities, the communications professional thought she'd find something at an oil and gas company, but then she met John Berger, founder and CEO of Sunnova, who was looking for someone to stand up their communications team amidst the solar energy company's growth.

"He hooked me," Hultberg shares on the Houston Innovators Podcast. "He said, 'I've got big plans for this company. I see where this energy industry is going, I see that we're prime for a transition, and I want to take this company public.' And I started a few weeks later."

Hultberg has been telling the story for Sunnova — which equips customers with solar and storage technology, providing them with energy independence — ever since, through scaling, new technologies, and its IPO in 2019.

Each phase of the company represented different challenges for Hultberg and her communications team. As she explains on the podcast, consistently conveying a strong message is key in any industry, but especially energy.

"Communication is critical," Hultberg says, "having a strategy and really being able to articulate who you are, what you stand for, what is your mission, what is your vision — and really beyond that, what is your strategy for how you move forward. ... You can never say the same thing to the same people too many times, especially when you're a company that some people have never heard of before."

And while there's a unique challenge to communications for energy transition companies, Hultberg says she views it as a huge opportunity as long as you have the right structure in place.

"Of course communications and being as strategic as possible with the story that you're telling and the narrative that you're weaving for your different audiences, but then you layer on an industry that's rapidly changing and is tumultuous at times," she says. "Being able to come back to the core mission and values is really incredible."

Hultberg says that when she originally joined the team in 2017, she thought a solar energy company in Houston was an interesting choice — and it was. Texas was not one of Sunnova's biggest markets at the time, Hultberg explains, but things are different now.

"Over the last couple of years, especially after Winter Storm Uri, where you saw a lot of people go without power. ... We had a lot of customers say, 'That can't happen again,'" she says. "You're seeing the adoption and uptick in solar in storage because they are looking for grid reliability and affordability and they aren't getting it from their utility providers."

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.
