The United Kingdom subsidiary of Houston-based cleantech startup Revolution Turbine Technologies has received a $200,000 grant from the U.K.’s Strategic Innovation Fund to help produce zero-emission electricity.

The project, led by Revolution Turbine Technologies (RTT) in tandem with regional utility Northern Gas Networks and British government agency Digital Catapult, will explore installation of RTT’s proprietary micro-turbines within the Northern Gas Networks’ natural gas distribution network. It’ll be the first time RTT’s technology has been introduced into the global market for natural gas distribution.

RTT’s U.K. subsidiary received the grant from the U.K.’s £450 million Strategic Innovation Fund. The fund backs projects that are designed to help U.K. energy systems reach net-zero targets.

RTT’s co-founder and CEO, Christopher Bean, says in a news release that the grant “will accelerate our development efforts and be instrumental in advancing commercialization of our technology.”

The RTT technology set to be added in the U.K. holds the potential to be rolled out in the U.S. and elsewhere in Europe in the effort to combat carbon dioxide emissions, Bean says.

“Launching 40 projects in parallel, involving 100 percent of the UK energy networks, shows we can embrace new approaches, move quickly, and take more calculated risks," says Matt Hastings, deputy director of the Ofgem SIF program at Innovate UK, in the release." We strongly believe we can make the UK the best place in the world to be an energy consumer, and the best place in the world to be an energy entrepreneur. Working together, we can use the Strategic Innovation Fund to help turn the UK into the ‘Silicon Valley’ of energy.

RTT’s cleantech harvests excess pressure in flows of natural gas to generate zero-emission, off-grid electricity for energy pipelines, energy facilities, and gas distribution networks.

RTT was accepted into Greentown Labs Houston’s first group of cleantech startups in 2020. The startup relocated its headquarters from Asheville, North Carolina, to Greentown Labs Houston last year. Also in 2021, John Jeffers and Tim Moor came aboard as co-founders. Jeffers is RTT’s chief marketing officer, and Moor is its chief technology officer.

According to Crunchbase, RTT raised $1.6 million in seed funding in 2015 and an undisclosed amount of seed funding in 2021.

5 can't-miss innovation events at CERAWeek featuring Houston speakers

where to be online

While usually hundreds of energy experts, C-level executives, diplomats, members of royal families, and more descend upon Houston for the the annual CERAWeek by IHS Markit conference, this year will be a little different. Canceled last year due to COVID-19, CERAWeek is returning — completely virtually.

The Agora track is back and focused on innovation within the energy sector. The Agora track's events — thought-provoking panels, intimate pods, and corporate-hosted "houses" — can be accessed through a virtual atrium.

Undoubtedly, many of the panels will have Houston representatives considering Houston's dominance in the industry, but here are five innovation-focused events you can't miss during CERAWeek that feature Houstonians.

Monday — New Horizons for Energy & Climate Research

The COVID-19 pandemic has made vivid and real the risks of an uncontrolled virus. Risks posed by climate change are also becoming more palpable every day. At the forefront of understanding these risks, universities are developing solutions by connecting science, engineering, business, and public policy disciplines. Along with industry and governments, universities are critical to developing affordable and sustainable solutions to meet the world's energy needs and achieve net-zero emission goals. Can the dual challenge of more energy and lower emissions be met? What is some of the most promising energy and climate research at universities? Beyond research, what are the roles and responsibilities of universities in the energy transition?

Featuring: Kenneth B. Medlock, III, James A. Baker, III, and Susan G. Baker Fellow In Energy And Resource Economics, Baker Institute and Senior Director, Center For Energy Studies at Rice University

Catch the panel at 1 pm on Monday, March 1. Learn more.

Tuesday — Conversations in Cleantech: Powering the energy transition

With renewables investment outperforming oil and gas investment for the first time ever in the middle of a pandemic, 2020 was a tipping point in the Energy Transition. Low oil prices intensified energy majors' attention on diversification and expansion into mature and emerging clean technologies such as battery storage, low-carbon hydrogen, and carbon removal technologies. Yet, the magnitude of the Energy Transition challenge requires an acceleration of strategic decisions on the technologies needed to make it happen, policy frameworks to promote public-private partnerships, and innovative investment schemes.

Three Cleantech leaders share their challenges, successes, and lessons learned at the forefront of the Energy Transition. What is their vision and strategy to accelerate lowering emissions and confronting climate change? Can companies develop clear strategies for cleantech investments that balance sustainability goals and corporate returns? What is the value of increasing leadership diversity for energy corporations? Can the Energy Transition be truly transformational without an inclusive workforce and a diverse leadership?

This Houston neighbor was the fastest growing U.S. city in last decade

Booming Burb

It's no secret that Houston's population is growing faster than most other metros in the U.S., but now a surprising Houston-area neighbor has been named the No. 1 fastest-growing suburb nationwide over the last decade: the booming city of Fulshear.

Fulshear led the nation with an astonishing 1,082 percent increase in population from 2014 to 2023, according to a recent growth study by marketplace platform StorageCafe.

Overall, Texas cities dominated StorageCafe's list of the top 10 fastest-growing U.S. cities from 2014 to 2023.

The report said the city had nearly 27,000 residents in 2023, but now the U.S. Census Bureau estimates Fulshear's population has now grown to more than 42,600 people.

"With its blend of a relaxed lifestyle, urban conveniences, top-rated schools and strong job opportunities, Fulshear consistently ranks among the best places to live in Texas," the report's author wrote.

This isn't the first time Fulshear has entered the spotlight for its exploding population: it was the No. 2 fastest-growing U.S. city in 2023, and recently came out on top of GoBankingRates' new study ranking of the fastest-growing affluent suburbs in America for 2025.

Several other Houston-area suburbs also saw major growth over the last decade, including Manvel (No. 24), Katy (No. 82), and Conroe (No. 83).

"Manvel doubled its population between 2014 and 2023, while Katy and Conroe each recorded increases of over 50 percent," the report said. "By contrast, Houston itself grew by just 6 percent, aligning with the average growth rate for large U.S. cities."

The report added that the Houston area's population surge has also led to a high demand for housing, where home values have risen 60 percent over the last 10 years. Home prices in Fulshear stood at more than $521,000 in November 2024, whereas Manvel's home prices were over $431,000 during that same period.

For comparison, the national average price of a home is $354,000.

Katy and Conroe had the most affordable home prices out of the four Houston suburbs in the report, at $347,740 and $318,952, respectively, for November.

StorageCafe says the reasons for population shifts vary greatly, with many people seeking out cities with a more affordable cost of living, or those moving for socioeconomic factors like better employment opportunities.

"Population growth is far from even across the U.S. Some cities are experiencing significant increases, directly driven by steady in-migration, rising immigration and birth rates outpacing death rates," the report said. "But what’s fueling these trends runs deeper — economic and social forces like shifting job markets, the rise of remote and hybrid work and soaring living costs are all reshaping where people choose to live."

Other fast-growing Texas cities
Texas had the greatest number of cities to earn spots in the report's ranking of the 100 fastest-growing U.S. cities over the last decade, with 25 total cities making the cut with the highest growth rates nationwide.

Dallas-Fort Worth had the highest number of fastest-growing Texas suburbs on the list, comprising 11 cities: Celina (No. 2), Melissa (No. 3), Princeton (No. 7), Prosper (No. 8), Fate (No. 9), Anna (No. 14), Midlothian (No. 33), Royse City (No. 43), Forney (No. 45), Little Elm (No. 58), and Frisco (No. 72).

Meanwhile, Austin had five suburbs land on the list: Manor (No. 6), Leander (No. 16), Kyle (No. 53), Hutto (No. 54), and Buda (No. 68).

San Antonio also had five suburbs make the top 100, including Boerne (No. 63), Selma (No. 74), Fair Oaks Ranch (No. 70), New Braunfels (No. 77), and Canyon Lake (No. 99).

The top 10 fastest-growing cities over the last decade are:

  • No. 1 – Fulshear, Texas
  • No. 2 – Woodbridge, Virginia
  • No. 3 – Celina, Texas
  • No. 4 – Davenport, Florida
  • No. 5 – Melissa, Texas
  • No. 6 – Manor, Texas
  • No. 7 – Princeton, Texas
  • No. 8 – Prosper, Texas
  • No. 9 – Fate, Texas
  • No. 10 – Nolensville, Tennessee

Houston space tech startups share latest updates on lunar missions and more

space update

Houston-based space tech companies Axiom Space and Intuitive Machines recently shared updates on innovative projects and missions, each set to launch by 2027.

Axiom Space

Axiom Space, developer of the world’s first commercial space station and other space infrastructure, is gearing up to launch two orbital data center nodes to low-earth orbit by the end of 2025.

The Axiom Space nodes will lay the foundation for space-based cloud computing. Axiom says orbital data centers provide cloud-enabled data storage and processing, artificial intelligence, and machine learning directly to satellites, constellations, and other spacecraft in Earth’s orbit. This innovation will reduce reliance on earth-based systems, enhance wireless mesh networks and improve real-time operation of space-borne assets, according to Axiom.

Axiom has been working on the development of orbital data centers since 2022. The two nodes going into space in 2025 will be part of Kepler Communications’ 10-satellite data relay network, which is scheduled to launch by the end of this year. Axiom Space and Kepler Communications have been collaborating since 2023.

Kam Ghaffarian, co-founder, executive chairman, and CEO of Axiom, says his company already has deals in place with buyers of space-based cloud computing services. Orbital data centers “are integral to Axiom Space’s vision of era-defining space infrastructure, unlocking transformational capabilities and economic growth,” he says.

Axiom Space says it will be able to buy additional payloads on Kepler’s network to boost capacity for orbital data centers. The two companies will team up to provide network and orbital data center services to various customers.

Intuitive Machines

Meanwhile, Intuitive Machines, a space exploration, infrastructure and services company, has picked SpaceX’s Falcon 9 rocket to launch its fourth delivery mission to the moon. The launch will include two lunar data relay satellites for NASA.

Intuitive Machines says its fourth lunar delivery mission is scheduled for 2027. The mission will comprise six NASA commercial lunar payloads, including a European Space Agency drill set designed to search for water at the moon’s south pole.

“Lunar surface delivery and data relay satellites are central to our strategy to commercialize the moon,” Intuitive Machines CEO Steve Altemus says.

The first of five lunar data relay satellites will be included in the company’s third delivery mission to the moon. The fourth mission, featuring two more satellites, will be followed by two other satellite-delivery missions.

Houston doctor aims to revolutionize hearing aid industry with tiny implant

small but mighty

“What is the future of hearing aids?” That’s the question that led to a potential revolution.

“The current hearing aid market and technology is old, and there are little incremental improvements, but really no significant, radical new ideas, and I like to challenge the status quo,” says Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist.

Moses is the creator of NanoEar, which he calls “the world’s smallest hearing aid.” NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power—and a superior hearing experience—than the best behind-the-ear hearing aid.

“You put the NanoEar inside of the eardrum in an in-office procedure that takes literally five minutes,” Moses says.

As Moses explains, because of how the human cochlea is formed, its nerves break down over time. It’s simply an inevitability that if we live long enough, we will need hearing aids.

“The question is, ‘Are we going to all be satisfied with what exists?’” he asks.

Moses says that currently, only about 20 percent of patients who need hearing aids have them. That’s because of the combination of the stigma, the expense, and the hassle and discomfort associated with the hearing aids currently available on the market. That leaves 80 percent untapped among a population of 466 million people with hearing impairment, and more to come as our population ages. In a nearly $7 billion global market, that additional 80 percent could mean big money.

Moses initially patented a version of the invention in 2000, but says that it took finding the right team to incorporate as NanoEar. That took place in 2016, when he joined forces with cofounders Michael Moore and Willem Vermaat, now the company’s president and CFO, respectively. Moore is a mechanical engineer, while Vermaat is a “financial guru;” both are repeat entrepreneurs in the biotech space.

Today, NanoEar has nine active patents. The company’s technical advisors include “the genius behind developing the brains in this device,” Chris Salthouse; NASA battery engineer Will West; Dutch physicist and audiologist Joris Dirckx; and Daniel Spitz, a third-generation master watchmaker and the original guitarist for the famed metal band Anthrax.

The NanoEar concept has done proof-of-concept testing on both cadavers at the University of Antwerp and on chinchillas, which are excellent models for human hearing, at Tulane University. As part of the TMC Innovation Institute program in 2017, the NanoEar team met with FDA advisors, who told them that they might be eligible for an expedited pathway to approval.

Thus far, NanoEar has raised about $900,000 to get its nine patents and perform its proof-of-concept experiments. The next step is to build the prototype, but completing it will take $2.75 million of seed funding.

Despite the potential for making global change, Moses has said it’s been challenging to raise funds for his innovation.

“We're hoping to find that group of people or person who may want to hear their children or grandchildren better. They may want to join with others and bring a team of investors to offset that risk, to move this forward, because we already have a world-class team ready to go,” he says.

To that end, NanoEar has partnered with Austin-based Capital Factory to help with their raise. “I have reached out to their entire network and am getting a lot of interest, a lot of interest,” says Moses. “But in the end, of course, we need the money.”

It will likely, quite literally, be a sound investment in the future of how we all hear the next generation.
