A Houston company has signed onto an offshore carbon storage deal in Denmark.

Fidelis New Energy Europe, the European arm of Houston-headquartered Fidelis New Energy, and Norway-based Carbon Centric have signed a letter of intent for Fidelis recently announced Norne Carbon Storage Hub in Denmark. With the agreement, Norne will "safely and permanently store CO2 emissions of Carbon Centric's clients," according to a news release.

"Norne enables the safe and environmentally friendly decarbonization of key segments of the Danish and European economies while ensuring industries remain globally competitive due to the low overall costs of CO2 mitigation," Bengt Jarlsjo, co-founder, president, and COO of Fidelis, says in a news release. "This announcement with Carbon Centric is an important milestone for the decarbonization of Denmark and Northern Europe. We look forward to our continued collaboration with Carbon Centric."

Carbon Centric plans to store around 800,000 tons of CO2 annually with Norne by 2027, according to the release, and the company's CO2 will be moved to Fidelis' CO2 reception facility at the Port of Aalborg. Carbon Centric has carbon management already underway in Norway and Iceland, with others planned in Denmark and Sweden.

"At Carbon Centric we have been looking for a company like Fidelis that will be able to ensure cost-effective large scale carbon storage for our clients. Norne is visionary with its ability to scale up quickly and will allow us to build out our businesses together," Kenneth Juul, Carbon Centric chief commercial officer and co-founder, says in the release. "With Denmark's foresight of moving quickly toward onshore carbon storage and with Fidelis' plans and prior three years of work on the Norne vision to provide carbon storage solutions on both Jutland and Zealand, we see a great opportunity to expand our activities in Denmark."

Carbon Centric is just the latest customer for the Norne Carbon Storage Hub, which was announced in May by Fidelis. The facility is billed as being "safe, ESG-friendly, and economically advantaged." The hub reportedly aims to store more than 20 million tons of CO2 per year by 2030.

Earlier this month, Fidelis New Energy selected Mason County, West Virginia selected Mason County, West Virginia, as the site for its carbon neutral hydrogen production facility and low carbon microgrid — The Mountaineer GigaSystem and the Monarch Cloud Campus for data centers powered by net-zero hydrogen.

Houston climatech startup raises $29M funding round​

fresh funding

Houston-based NanoTech Materials has closed a $29.4 million Series A.

The round was led by Austin-based HPI Real Estate & Investments. Houston-based Goose Capital and Austin-based Milliken & Company also participated.

Nanotech has developed its patented Insulative Ceramic Particle (ICP) technology, which reduces heat transfer in buildings and outdoor infrastructure, improving efficiency and safety. It's known for its Cool Roof Coat, Wildfire Shield and Insulative Coat: Cool Touch product lines.

With the new funding, Nanotech plans to scale operations and expand its market reach for its products.

“We’re addressing one of the pressing and urgent challenges facing infrastructure owners today: controlling energy costs and extending asset life,” Mike Francis, CEO and co-founder of NanoTech Materials, said in a news release. “This financing marks a transformative moment for us. It allows us to rapidly scale production and bring our high-performance materials to market faster, while delivering measurable cost savings and redefining what resilience looks like in today’s built environment.”

Nanotech launched in 2020 and was the first company selected for Halliburton Labs. It moved into a 43,000-square-foot space in Katy in 2023. It brought on new partners that expanded the company's reach in the Middle East and Singapore the following year. Its technology was recognized as one of Time magazine's 200 Best Inventions of 2024.

“We were early investors in Nanotech Materials and are pleased to continue supporting the company as it becomes a leader in breakthrough materials science and technology,” John Chaney, investor at Goose Capital and board member at NanoTech, added in the release. “NanoTech’s ability to elevate fire resilience and energy efficiency in the built environment is critical for strengthening and hardening infrastructure. Its pioneered approach is transforming current building standards and making our lives safer.”

The company has secured $34.4 million in total to date, according to the release. It raised an oversubscribed funding round in 2023 and a $5 million seed round in 2020.

Houston clean energy startup acquired by battery storage company FlexGen

m&a activity

A North Carolina company has acquired Houston-based Clean Energy Services, a provider of services for battery energy storage systems and utility-scale solar, for an undisclosed amount.

The buyer is Durham, North Carolina-based FlexGen Power Systems, a provider of battery energy storage software and services.

Clean Energy Services (CES), whose offices are at the Ion, will operate as a subsidiary of FlexGen. Existing CES customers will continue to receive services from CES without disruption or change, FlexGen says.

“Demand for reliable, high-performance power is accelerating, and customers need partners who can deliver at scale,” Kelcy Pegler, CEO of FlexGen, said in a news release. “The addition of CES strengthens our service platform and reinforces our leadership in energy storage technology.”

Ahmad Atwan and Constantine Triantafyllides co-founded CES in 2022. As a startup, CES had raised $8 million in venture capital, according to PitchBook.

“CES has achieved a market leadership position in battery storage services by focusing on reliable speed of service delivery and optimizing asset performance,” Atwan, the company’s CEO, added the release. “FlexGen and CES have been strong partners for years, and this transaction enables us to deliver more robust solutions across a complementary set of customers and markets.”

CES will continue to operate its remote operations center in Houston for over 1 gigawatt of solar assets and 4.5 gigawatt-hours of battery assets, while FlexGen will maintain its remote operations center in Durham.

Halliburton Labs names 4 new clean energy startups to incubator

green team

Four new companies have joined Halliburton Labs, the incubator for early-stage energy and climate startups run by Houston energy giant Halliburton.

Halliburton Labs provides the emerging companies with mentorship, industry connections, laboratory access and other resources as they work toward commercialization, according to a news release.

The four new members include:

  • Nandina REM, a Singapore-based company that delivers carbon fiber thermoplastics. It turns end-of-life assets into new, reliable, high-performance materials for the aviation, aerospace and defense industries in a fraction of the time of standard supply chains.
  • Noon Energy, a California-based company that delivers clean, reliable electricity with ultra-long duration energy storage. Its system uses solid oxide electrochemical cells and stores energy as abundant, flexible industrial gases.
  • Proof Energy, a Silicon Valley-based company developed by the Lawrence Berkeley National Laboratory that is commercializing next-generation metallic solid oxide fuel cell (M-SOFC) technology. Its system uses widely available fuels such as ethanol, methanol, ammonia, and natural gas as hydrogen carriers to enable lower-cost, low-emission commercial transportation, and also offers a zero-emission heating solution to preserve battery range in electric vehicles.
  • Tidal Metals, a New Jersey-based company that has developed technology to economically make decarbonized magnesium metal from seawater and electricity.

"Halliburton Labs exemplifies our commitment to advance a secure and pragmatic energy future," Jeff Miller, chairman, president and CEO of Halliburton, said in the news release. "We welcome these companies into our ecosystem, where they will gain access to the tools, expertise, and connections needed to scale their technologies."

Auckland-based Aquafortus Technologies and California-based Sunchem joined Halliburton Labs in September. With the addition of the four new members, the incubator currently supports six early-stage companies.
