A Houston company has teamed up with a Utah-based sustainable cement alternatives producer to construct eco-friendly homes made from 3D-printed pieces.

HIVE 3D was already revolutionizing the home-builder industry with its lightweight gantry system and mobile robotic arm system to 3D print its homes, but it took a giant leap further with its partnership with Eco Material Technologies.

Together, they are building the world’s first near-zero-carbon, 3D-printed homes. Using Eco Material’s cement mixture called PozzoCEM Vite, which has 92 percent lower emissions than traditional concrete that can set in just a few minutes, they are focusing on providing a sustainable, cost-efficient and affordable housing solution.

“We want our homes to last 1,000 years,” Timothy Lankau, CEO, Hive 3D CEO, tells InnovationMap. “We want archaeologists to dig them up and wonder what they were. I mean, you go to the Parthenon in Rome, and it looks similar today to how it did 2,000 years ago because the materials are so stable.

“Concrete's just a very stable material. It doesn't change over time, and that's also why building with stone and masonry is important for the future. We think it's more sustainable because it's ultimately going to be better in terms of longevity.”

Key collaboration

Eco Material Technologies and HIVE 3D’s collaborative mission began through a mutual desire to develop sustainable and eco-friendly solutions for the construction industry.

“Both companies recognized the pressing need to reduce the environmental impact of traditional construction materials and processes and the need for affordable, high-quality housing,” says Grant Quasha, CEO of Eco Material Technologies. “The partnership between the two companies began when Eco Material Technologies reached out to HIVE 3D to explore the potential of incorporating their eco-friendly materials into 3D printed construction.

“HIVE 3D recognized the opportunity to combine their expertise with sustainable material solutions. The finished product of this collaboration is an eco-friendly construction material that can be 3D printed into various structural elements like walls, floors and columns.”

Proof of concept

HIVE 3D’s first full project, a 3,150-square-foot home located in Burton, Texas, was printed with a rotating team of just four people using PozzoSlag, which replaces 50 percent of the portland cement in concrete and has been used in roads and bridges in Texas for over a decade.

The home used several innovations that hadn’t been used in a 3D printed house before, including parametric wall designs, foamcrete wall insulation, and pigmented concrete layers.

“Our product is more sustainable because it utilizes proprietary technology that allows for the use of alternative materials to replace the clinker and processes from traditional cement that contribute to its high emissions,” says Quasha. “It is estimated that the portland cement industry contributes to 8 percent of global emissions annually, but by utilizing Eco Material Technologies' cement replacement solutions ... builders can significantly decrease their carbon emissions without compromising on the product's setting time or long-term strength."

Each ton of portland cement replaced by a ton of Eco Material's products, PozzoSlag or Pozzocem, reduces emissions by close to one ton, Quasha explains.

The Calais project, located in Round Top, Texas, behind the Halles, an antique shopping and design destination, broke ground in March 2023 and will feature a collection of tiny homes known as casitas, including studio, single-bedroom and two-bedroom models, ranging from 400 to 900 square feet.

“These small homes will serve as a model for affordable and eco-friendly housing throughout the country,” says Lankau. “We plan to build them at a speed and cost point that is unprecedented in the affordable housing space.

“Ultimately, we want to build houses at a disruptive price point. We want to be vertically integrated and put our homes on the market at a significant discount to market wherever they are. And by significant, we're talking 20 or 30 percent. That's our goal.”

The right resources

HIVE 3D worked with CyBe Construction to create a mobile construction 3D printer and mixing system that allows the printing mortar to be mixed onsite, which eliminates a significant amount of labor and time, which means those savings can be passed on to the consumer.

“We worked with a company called CyBe in the Netherlands to build a robotic arm, and that arm has about an 11-foot reach, and it can go all the way in a circle around itself,” says Lankau. “So, it drives around the foundation of the house, printing sections of the house at a time. So, it'll print a section, drive to the next section, and print the next section.

“So instead of having this many different materials and these many different traits, people that do all these different things, we have a machine that just uses one material and prints the wall.”

HIVE 3D has an internal engineer that works through all of the structural issues that may come up on projects and helps them build homes with monolithic, foot-thick concrete walls with rebar and steel supported in them.

According to Lankau, their 3D printed homes are tornado-proof, hurricane-proof, pest-proof, bullet-proof and can virtually withstand anything because of the sustainable materials used to build them.

“They're everything-proof,” says Lankau. “Just because of the natural strength of the concrete and the steel we use to create them, they can support millions of pounds. So, it's actually a stronger material than a typical house. By a factor of 100. Like I said, it's bulletproof and tornado-proof. You could drive a car into it, and it would total the car. I mean, it's a very, very sturdy structure.”

A bright future

Moving forward, HIVE 3D would like to continue to innovate and advance its 3D printing technology by leaps and bounds.

“The science fiction goal here, which is maybe a five-year goal, is to be able to drive onto a site, press a button, and watch the robots work,” says Lankau. “We want to be a significant home builder. So, in five years, we want to be building a lot of houses quickly and affordably and we want to continue to automate more and more of the process.”

Right now, there is no formal process for commissioning a HIVE 3D printed home. Perspective customers are directed to the website, then put in a request to build a home, go through a screening process and if the project is a good fit, they'll put that project into their pipeline.

“We can build them quickly. It's just a matter of getting to them,” says Lankau. “We're also going to be doing some developments in Texas probably to start. We also have some international things that we'll be looking into next year. But right now, it's mostly in Texas. We'll be building some developments and putting those homes on the market. We hope to have some out this year and then a bigger chunk next year as we get more machines working. Those will be announced on our website.”

As HIVE 3D continues to find ways to scale its business model, there is a laser focus on the diminishing idea of the “American Dream,” where young families are able to purchase their first home. With the rising costs of supplies and labor, those families have been priced out of the market.

“That’s almost all we think about,” says Lankau. “Homeownership and that part of the American Dream is really struggling right now because the affordability gap between what the average person makes and what the average house on the market costs is just getting wider and wider.

According to Lankau, there are a lot of options to address the supply gap, but there aren’t an equal number of options to solve the affordability issue. Their goal is to find the best ways to deliver real cost savings over both traditional construction and other automated technologies.

“About three weeks ago, we kind of hit the inflection point in our current project where we printed a little house in three days. The cost of the house was what we wanted the cost to be, which is a disruptive amount less than what you could do traditionally or with any other construction technique. And we said, okay, now we're far enough along. We have this system. It's a scalable system. So, we're right now putting some capital together to go out and buy, build more of these machines and get out and start doing these truly affordable housing projects. Because that's where our heart is. Our heart's on the affordable side.”

HIVE 3D’s project in Burton, Texas isn’t available for sell yet, but it will be listed on Airbnb for interested customers to go and experience when it’s completed.

Additionally, the Casitas units in Round Top will be short-term rentals for festival patrons.

“We’ll go directly to market with our next projects,” says Lankau. “And then we'll sell that big house property in Burton at the end of this year.”

Enbridge's new Texas solar project to power Meta data centers

solar deal

Construction is underway on a new 600-megawatt solar project in Texas that will supply renewable energy to Meta Platforms Inc., the owner of Facebook, Instagram and other tech platforms.

Calgary-based Enbridge Inc., whose gas transmission and midstream operations are based in Houston, announced that Meta has agreed to purchase 100 percent of the power generated by its new $900 million solar project known as Clear Fork.

The clean energy developed at Clear Fork will be used to support Meta’s data center operations, according to a news release from Enbridge. Meta has had net-zero emissions across its operational portfolio since 2020, according to its 2024 environmental report. The company matches 100 percent of its data center usage with renewable energy.

"We are thrilled to partner with Enbridge to bring new renewable energy to Texas and help support our operations with 100% clean energy, " Urvi Parekh, Head of Global Energy at Meta, said in a news release.

The Clear Fork project is expected to be operational by the summer of 2027. It will join Enbridge’s first solar power project in Texas, Orange Grove, which was activated earlier this year, as well as the company’s Sequoia solar project, which is scheduled to go online in early 2026.

"Clear Fork demonstrates the growing demand for renewable power across North America from blue-chip companies who are involved in technology and data center operations," Matthew Akman, executive vice president of corporate strategy and president of power at Enbridge, said in the news release. "Enbridge continues to advance its world-class renewables development portfolio using our financial strength, supply chain reach and construction expertise under a low-risk commercial model that delivers strong competitive returns."

Energy experts: Executive order enhances federal permitting for AI data centers

Guest column

In an effort to accelerate the development of artificial intelligence, President Trump signed an executive order (EO) aimed at expediting the federal permitting process for data centers, particularly those supporting AI inference, training, simulation, or synthetic data generation.

Following the White House’s issuance of a broader AI Action Plan, the EO seeks to streamline regulatory burdens and utilize federal resources to encourage the development of data centers supporting AI, as well as the physical components and energy infrastructure needed to construct and provide power to these data centers.

Qualifying Projects

The EO directs several federal agencies to take actions to incentivize the development of “Qualifying Projects,” which the EO defines as “Data Centers” and “Covered Component Projects.” The EO defines “Data Center Projects” as facilities that require over 100 megawatts (MW) of new load dedicated to AI inference, training, simulation, or synthetic data generation. The EO defines Covered Component Projects as materials, products, and infrastructure that are required to build Data Center Projects or upon which Data Center Projects depend, including energy infrastructure projects like transmission lines and substations, dispatchable base load energy sources like natural gas, geothermal, and nuclear used principally to power Data Center Projects, and semiconductors and related equipment. For eligibility as a Qualifying Project, the project sponsor must commit at least $500 million in capital expenditures. Data Center Projects and Covered Component Projects may also meet the definition of Qualifying Project if they protect national security or are otherwise designated as Qualifying Projects by the Secretary of Defense, Secretary of the Interior, Secretary of Commerce, or Secretary of Energy.

Streamlining Permitting of Qualifying Projects

The EO outlines the following strategies aimed at improving the efficiency of environmental reviews and permitting for Qualifying Projects:

  • NEPA Applicability: The Council on Environmental Quality (CEQ), in coordination with relevant agencies, is directed to utilize existing and new categorical exclusions under the National Environmental Policy Act (NEPA) to cover actions related to Qualifying Projects, which “normally do not have a significant effect on the human environment.” The EO states that where federal financial assistance represents less than 50 percent of total project costs of a Qualifying Project, the Project shall be presumed not to be a “major Federal action” requiring NEPA review.
  • FAST-41: The Executive Director of the Federal Permitting Improvement Steering Council (FPISC) is empowered to designate a Qualifying Project as a “transparency project” under the Fixing America’s Surface Transportation Act (FAST-41) and expedite its transition from a transparency project to a “covered project” under FAST-41. FPISC is directed to consider all available options to designate a Qualifying Project as a FAST-41 covered project, even where the Qualifying Project may not be eligible.
  • EPA Permitting: The US Environmental Protection Agency (EPA) is directed to modify applicable regulations under several environmental protection statutes impacting the development of Qualifying Projects on federal and non-federal lands. EPA is also directed to develop guidance to expedite environmental reviews for identification and reuse of Brownfield and Superfund Sites suitable for Qualifying Projects. Importantly, state environmental permitting agencies are not subject to the EO.
  • Corps Permitting: The US Army Corps of Engineers is directed to review the nationwide permits issued under Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act of 1899 to determine whether an activity-specific nationwide permit is needed to facilitate the efficient permitting of activities related to Qualifying Projects.
  • Interior Permitting: The US Department of the Interior is directed to consult with the US Department of Commerce regarding the streamlining of Endangered Species Act consultations for Qualifying Projects, and to work with the US Department of Energy to identify federal lands that may be available for use by Qualifying Projects and offer appropriate authorizations to project sponsors.

Federal Incentives for Qualifying Projects

The EO also directs the US Secretary of Commerce to “launch an initiative to provide financial support for Qualifying Projects,” which may include loans, grants, tax incentives, and offtake agreements. The EO further directs all “relevant agencies” to identify and submit to the White House Office of Office of Science and Technology Policy any relevant existing financial support that can be used to assist Qualifying Projects, consistent with the protection of national security.

The EO reinforces the Trump administration’s focus on AI and creates new opportunities for both AI data center developers and energy infrastructure companies providing power or project components to these data centers. Proactive engagement with relevant agencies will be crucial for capitalizing on the opportunities created by this EO and the broader AI Action Plan. By leveraging these financial and environmental incentives, project developers may be able to shorten permitting timelines, reduce costs, and take advantage of federal financial support.
