Investors at the Rice Alliance Energy Tech Venture Forum have named the 10 most-promising startups among the group of 100 clean tech companies participating in the event.

The 22nd annual event was held yesterday, Sept. 18, at Rice University’s Jones Graduate School of Business and was part of the second Houston Energy and Climate Startup Week.

The most-promising startups will receive $7,000 in in-kind legal services from Baker Botts.

The 10 most-promising companies included:

Houston-based Xplorobot, which has developed laser gas imaging technology for the first handheld methane detection device approved by the EPA as an alternative test method
Seattle-based Badwater Alchemy, a desalination company that uses nano materials to purify saline water at a fraction of the cost of traditional methods
San Francisco-based Ammobia, which is developing a clean ammonia production process
Illinois-based Celadyne Technologies, which is building hydrogen for industrial decarbonization with durable and efficient fuel cells and electrolyzers
Massachusetts-based MacroCycle Technologies, which converts plastic waste in the form of bottles, food trays and polyester textiles into virgin-grade mPET resin
Massachusetts-based AtoMe, which uses nano-ceramics to develop ultra-durable metals for 3D printing
Colorado-based Advanced Thermovoltaic Systems (ATS) Energy, a renewable energy semiconductor manufacturing company
North Carolina-based Lukera Energy, which is converting waste methane into high-value fuel
Midland, Texas-based AI Driller, a company that uses AI and machine learning to enable remote operations and provide historical drilling data for survey management, anti-collision monitoring and iob reporting
New York-based Fast Metals Inc., which has developed a chemical process to extract valuable metals from complex toxic mine tailings that is capable of producing iron, aluminum, scandium, titanium and other rare earth elements using industrial waste and waste CO2 as inputs

Arculus Solutions won the People's Choice Award. The New Jersey-based company retrofits natural gas pipelines for safe hydrogen transportation. It also won Track A: Hydrogen, Fuel Cells, Buildings, Water, & Other Energy Solutions at the Energy Venture Day and Pitch Competition during CERAWeek earlier this year.

The 100 energy technology ventures selected to participate in the forum were named earlier this year. See the full list here.

Houston data center capacity could more than double by 2028, CBRE report says

data analysis

The Houston market could more than double its data center capacity by the end of 2028, a new report indicates.

The report, published by commercial real estate services provider CBRE, says greater demand for data center capacity in the Houston area is being fueled by energy companies, along with large-scale cloud services and AI-driven tenants.

In the second half of 2025, the Houston market had 154 megawatts of data center capacity, which was on par with capacity in the second half of 2024. Another 28.5 megawatts of capacity was under construction during that period.

“Multiple providers are advancing new builds and redevelopments, including significant power upgrades to recently purchased buildings, underscoring long-term confidence even as the market works through elevated vacancy and uneven absorption,” CBRE says of Houston’s data center presence.

One project alone promises to significantly boost the Houston market’s data center capacity. Data center developer Serverfarm plans to use part of a $3 billion credit facility to build a 250-acre, AI-ready data center campus near Houston with a potential capacity of more than 500 megawatts. The Houston campus and two other Serverfarm projects are already leased to unidentified tenants, according to CoStar.

A 60-megawatt, AI-ready Serverfarm data center is under construction in Houston. The $137 million, 438,000-square-foot project, located near the former headquarters of computer manufacturer Compaq, is supposed to be completed in the third quarter of 2027.

Data Center Map identifies 59 data centers in the Houston area managed by 36 operators, including DataBank, Data Foundry, Digital Realty, IBM, Logix Fiber Networks, Lumen and TRG Datacenters. That compares with more than 180 data centers in Dallas-Fort Worth, more than 50 in the San Antonio area and 40 in the Austin area.

Texas is home to more than 400 data centers, according to Data Center Map.

In November, Google said it’s investing $40 billion to build AI data centers in West Texas and the Texas Panhandle.

“This is a Texas-sized investment in the future of our great state,” Gov. Greg Abbott said when Google’s commitment was announced. “Texas is the epicenter of AI development, where companies can pair innovation with expanding energy. Google's $40 billion investment makes Texas Google's largest investment in any state in the country and supports energy efficiency and workforce development in our state.”

Houston energy transition ecosystem rebrands as 'Energytech Cypher'

new look

Houston-based Energytech Nexus has rebranded.

The cleantech founders community will now be known as Energytech Cypher. Organizers say the new name was inspired by the Arabic roots of the word cypher, ṣifr, which is also the root of the word zero.

"A cypher is a key that unlocks what's hidden," Nada Ahmed, co-founder and chief revenue officer of Energytech Cypher, said in a news release. "And zero? Zero is where every transformation begins, the leap from 0 to 1, from idea to reality, from potential to power. We decode the energy transition by connecting the right founders, the right capital, and the right corporate partners at the right time, because the most important journey in energy is the one that takes you from nothing to something."

Energytech Nexus has rebranded to Energytech Cypher.

Co-founder and CEO Jason Ethier says that the name change better reflects the organization's mission.

"The energy transition doesn't have a technology problem. It has a connection problem," Ehtier added in the release. "The right founders exist. The right investors exist. The right partners exist. What's been missing is the infrastructure to bring them together—to decode the complexity, remove the friction, and make sure the best technologies find the markets that need them. That's what this community has always done. Energytech Cypher is the name that finally says it."

Energytech Cypher, previously known as Energytech Nexus, was first launched in 2023 and has grown from a podcast to a 130-member ecosystem. It has supported startups including Capwell Services, Resollant, Syzygy Plasmonics, Hertha Metals, Solidec and many others.

It is known for its flagship programs like the Pilotathon, which connects founders with industry partners for pilot opportunities. The event debuted in 2024.

Energytech Cypher also launched its COPILOT Accelerator last year. The accelerator partners with Browning the Green Space, a nonprofit that promotes diversity, equity and inclusion (DEI) in the clean energy and climatech sectors. The inaugural cohort included two Houston-based startups and 12 others from around the U.S.

It also hosts programs like Liftoff, Energy Tech Market, lunch and learns, CEO roundtables, investor workshops and international partnership initiatives.

Last year, Energytech Cypher also announced a new strategic ecosystem partnership with Greentown Labs, aimed at accelerating growth for clean energy startups. It also named its global founding partners, including Houston-based operations such as Chevron Technology Ventures, Collide, Oxy Technology Ventures, and others from around the world.
