1. Securing a commercial pilot

"As an early-stage clean energy developer, we struggled to convince key suppliers to work on our commercial pilot project. Suppliers were skeptical of our unproven technology and, given limited inventory from COVID, preferred to prioritize larger clients. We overcame this challenge by bringing on our top suppliers as strategic investors. With a long-term equity stake in Fervo, leading oilfield services companies were willing to provide Fervo with needed drilling rigs, frack crews, pumps, and other equipment." — Tim Latimer, founder and CEO of Fervo Energy

2. Finding funding

"Securing funding in Houston as a solo cleantech startup founder and an immigrant with no network. Overcome that by adopting a milestone-based fundraising approach and establishing credibility through accelerator/incubator programs." — Anas Al Kassas, CEO and founder of INOVUES

"The biggest challenge has been finding funding. Most investors are looking towards software development companies as the capital costs are low in case of a risk. Geothermal costs are high, but it is physical technology that needs to be implemented to safety transition the energy grid to reliable, green power." — Cindy Taff, CEO of Sage Geosystems

3. Market adoption

"Market adoption by convincing partners and government about WHP as a solution, which is resource-intensive. Making strides by finding the correct contacts to educate." — Janice Tran, CEO and co-founder of Kanin Energy

"We are creating a brand new financial instrument at the intersection of carbon markets and power markets, both of which are complicated and esoteric. Our biggest challenge has been the cold-start problem associated with launching a new product that has effectively no adoption. We tackled this problem by leading the Energy Storage Solutions Consortium (a group of corporates and battery developers looking for sustainability solutions in the power space), which has opened up access to customers on both sides of our marketplace. We have also leveraged our deep networks within corporate power procurement and energy storage development to talk to key decision-makers at innovative companies with aggressive climate goals to become early adopters of our products and services." — Emma Konet, CTO and co-founder of Tierra Climate

4. Long scale timelines

"Scaling and commercializing industrial technologies takes time. We realized this early on and designed the eXERO technology to be scalable from the onset. We developed the technology at the nexus of traditional electrolysis and conventional gas processing, taking the best of both worlds while avoiding their main pitfalls." — Claus Nussgruber, CEO of Utility Global

Houston innovator on the impact of facade enhancement on the energy transition

guest column

Imagine a world where outdated building facades transform overnight into modern marvels without the chaos of construction or the burden of exorbitant costs.

In the recent podcast episode on Energy Tech Startups, Anas Al Kassas, the CEO of INOVUES, unveils a groundbreaking technology that promises just that. This isn't just about a facelift; it's about revolutionizing energy efficiency, embracing smart-class innovations, and redefining the aesthetics of urban landscapes.

The Advantages of Facade Technology

One of the key advantages Al Kassas highlighted was the ability to significantly reduce both the cost and environmental impact of upgrading building facades. Al Kassas explained that by utilizing INOVUES' technology, the existing systems can be updated and improved without the need for removing or discarding the windows. This approach not only saves on material costs but also avoids disruption during installation. Additionally, the fast installation process and lower labor costs further contribute to the overall cost-effectiveness of the solution.

The Role of Design Aesthetics in Building Upgrades

While energy efficiency is a primary driver for building upgrades, Al Kassas emphasized the importance of design aesthetics in the commercial real estate market. He explained that modernizing the appearance of older buildings, which may still perform well but suffer from outdated perceptions, can attract more tenants and make them more competitive. With INOVUES' solution, building owners have the opportunity to improve the aesthetics of their facades by incorporating the latest glass technologies, colors, and frit patterns (translucent patterns on glass). This not only enhances the building's appearance but also contributes to glare reduction and customization options for different tenants' needs.

The Potential for Rentable Facades

During the conversation, Al Kassas speculated about the potential for rentable facades powered by INOVUES' technology. Just as Apple offers an upgrade plan for its devices, this concept proposes a similar model for building owners to continually incorporate the latest technologies every few years. By avoiding upfront costs and providing immediate benefits such as lower energy bills, improved tenant satisfaction, and a more sustainable building, this rentable facade approach could revolutionize the industry and make energy-efficient upgrades more accessible for a wider range of buildings.

The Current Funding Landscape and Future Growth

INOVUES' journey in securing funding, as discussed in the podcast, sheds light on the challenges faced by energy tech startups. The CEO highlighted the importance of timing and identifying the right investors who share the vision and understand the industry landscape. Despite the difficulties, INOVUES has successfully raised capital, including participation from a multinational building technology company. The company's next goal is to secure a series A funding round to scale their operations and expand their footprint in the market.

INOVUES' technology represents a sustainable solution for upgrading building facades without the need for extensive removal or disruptions. The combination of energy efficiency, improved design aesthetics, and the potential for rentable facades showcases the versatility and value of the company's technology. As the demand for sustainable building solutions continues to grow, and regulatory changes support energy efficiency projects, INOVUES is poised to make a significant impact in the industry. By focusing on both environmental and economic benefits, they are positioning themselves as a key player in the energy tech startup landscape.

Houston sustainability startup secures major milestone for energy efficient tool

patent progress

A Houston company that retrofits windows with smart glass innovations to reduce energy use is celebrating a handful of patents across North America and China.

INOVUES announced it secured several new patents from the United States Patent and Trademark Office, the Canadian Intellectual Patent Office, and the China National Intellectual Property Administration.

“These newly awarded patents reinforce our commitment to innovation and position us as a trusted partner for investors and industry partners,” says Anas Al Kassas, INOVUES founder and CEO, in a news release.

The company now has a total of four patents granted in the United States, Canada, and China, and four more patents pending in the United States, Canada, and the European Union. Additionally, INOVUES has trademark protection granted in the EU, United Kingdom, and China.

INOVUES's unique window treatment — its Insulating Glass Retrofit (IGR) and Secondary Glass Retrofit (SWR) technologies — directly impacts the built environment. The process includes 70 percent fewer materials compared to traditional methods and building owners see a 40 percent reduction in reduction in energy consumption following installation.

Last year, the company raised $2.75 million in venture funding. Kassas said at the time that the funding was slated o be used to scale up the team and identify the best markets to target customers, adding that he was looking for regions with rising energy rates and sizable incentives for companies making energy efficient changes.

"We were able to now implement our technology in over 4 million square feet of building space — from Boston, Seattle, Los Angeles, New York City, Portland, and very soon in Canada," he said in a December episode of the Houston Innovators Podcast.

SLB and NVIDIA expand partnership to scale AI across energy sector

AI partnership

Houston-based energy technology company SLB has expanded its 18-year tech collaboration with chipmaker NVIDIA to include the development of an “AI factory for energy.”

Through their partnership, SLB and NVIDIA will create AI infrastructure and models built around SLB’s existing digital platforms to help energy companies scale AI for data and operations.

In addition to the development of the “AI factory,” SLB will:

Provide modular design services to enhance NVIDIA’s blueprint for building, launching and operating gigawatt-scale AI data centers. In this case, modular design involves manufacturing data center components off-site.
Use NVIDIA’s AI infrastructure to improve the processing of large datasets and AI models across SLB’s digital platforms.

Energy companies generate vast amounts of operational data, which can slow down and silo decision-making, SLB says. By combining NVIDIA’s Omniverse libraries and its Nemotron open models with SLB’s digital and AI platforms, the companies aim to more rapidly transform data into actionable insights.

Omniverse libraries are sets of prebuilt 3D elements, such as objects, surfaces and interactive features, that make it easier to construct detailed virtual spaces without having to design everything manually. They’re commonly used for building immersive environments, digital replicas of real-world systems and simulation scenarios.

Nemotron open models are AI models that are freely available to download and modify. Instead of relying on a hosted service, you can run them on your own infrastructure and tailor them to fit specific needs.

Vladimir Troy, vice president of AI infrastructure at NVIDIA, says the energy sector is at the forefront of AI driving a “new industrial revolution.”

“The winners in AI will be companies with the best data, the deepest domain expertise, and the ability to scale,” Demos Pafitis, SLB’s chief technology officer, added. “By collaborating with NVIDIA to advance modular data center construction and harness our domain expertise and digital platforms, we’re enabling the energy industry to deploy AI at scale and transform operational data into smarter decisions.”

Oxy CEO Vicki Hollub to retire, Reuters reports

retirement plans

Vicki Hollub, CEO of Houston-based Occidental (Oxy), is set to retire this year, Reuters first reported Thursday.

Hollub has held the top leadership position at Oxy since 2016 and has been with the oil and gas giant for more than 40 years. Before being named CEO, she served as chief operating officer and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Reuters reports that a firm date for her retirement has not been set. Richard Jackson, who currently serves as Oxy's COO, is expected to replace Hollub in the CEO role.

Oxy is leading a number of energy transition projects.

It's subsidiary 1PointFive is developing a $1.3 billion direct air capture (DAC) project in the Midland-Odessa area that is slated to be the largest facility of its kind in the world. Known as STRATOS, it's designed to capture up to 500,000 metric tons of CO2 per year.

The company shared recently that Phase 1 of the project is expected to go online in Q2, with Phase 2 ramping up through the remainder of 2026.

“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 last year.

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

Oxy was one of the first to set ambitious net-zero goals. In a 2020 interview during CERAWeek, Hollub outlined Oxy's future as a “carbon management company.”

“Ultimately, I don’t know how many years from now, Occidental becomes a carbon management company, and our oil and gas would be a support business unit for the management of that carbon. We would be not only using [CO2] in oil reservoirs [but] capturing it for sequestration as well,” Hollub said.

Oxy opened its Oxy Innovation Center in the Ion last year, focused on advancing low-carbon technology. It also operates Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others.
