Houston is home to some of the nation's largest oil and gas exploration and production firms, making it one of the world’s most important energy capitals. Growing regional support for pioneering clean tech, such as carbon capture, will help achieve the crucial transition to net zero whilst maintaining economic stability, boosting local industries and creating jobs.

According to the International Energy Agency (IEA), North America and Asia Pacific are expected to hold the largest share in carbon capture capacity. North America’s world-leading carbon capture potential comes as no surprise given the nation’s dominance in oil and gas, and ideal geology for sequestration.

The IEA’s recently published World Energy Outlook 2023 depicts a global market that is in transition. With more companies, world leaders and governments recognizing that a shift towards sustainable energy is both inevitable and transformative, the question is no longer whether we switch to clean energy, but rather how soon the transition can happen.

For every $1 in investment spending on fossil fuels globally, $1.8 is now being spent to develop clean energy, according to the IEA. Although the clean energy market has almost doubled in the past five years to reach an estimated $2.8 trillion in 2023, investment needs to hit $4.2 trillion per year by 2030 to achieve the universally shared goal of net zero. The IEA believes around 1 Gigaton of CO2 must be captured in 2030, rising to 6 Gigatons by 2050 to achieve the Net Zero Emissions by 2050 Scenario (termed NZE Scenario). This presents a tremendous opportunity for government stakeholders and the business community in Houston to turbocharge the economy and protect the planet from the impact of climate change.

While volatility around the energy market lingers, sustainable technologies remain one of the most dynamic areas of global energy investment. An essential ingredient to its success is bringing on board innovators, entrepreneurs, corporations, and financiers to ensure technology innovation is front and center in facilitating the clean energy transition.

Carbon capture technology is critical, but energy leaders and hard-to-abate industries are under pressure to move faster. To do that, the carbon capture industry must scale up its deployment and increase adoption if hard-to-abate sectors are to address the 30 percent of global CO2 emissions for which they are responsible. Governments have a pivotal role to play in providing financial, regulatory and policy incentives, facilitating a collaborative environment between financiers, hard-to-abate operators, and clean tech companies. While we are moving in the right direction, there is no room for complacency or procrastination given the short timescales for meaningful action.

Over the past several years, Carbon Clean, a global company that is revolutionizing carbon capture, has enjoyed significant expansion in North America. Following the passage of the Inflation Reduction Act (IRA) in August 2022, we saw huge interest in our modular industrial carbon capture technology almost overnight, resulting in a 64 percent increase in inquiries from the U.S. To meet this booming demand, we have opened a U.S. headquarters in Houston, and have plans to double our U.S. headcount to meet industry requirements for our scalable and cost-effective technology, CycloneCC. In short, the United States is poised to become our biggest market. Given our latest lead investor and partner is Houston-based Chevron New Energies, there is no better place than Houston to drive innovation in the country’s energy sector.

The IRA did more than just bring in new inquiries for our breakthrough technology – it also signaled to the energy sector that the federal government is getting serious about bringing emissions down. The impact of the IRA cannot be overstated, especially for the point-source carbon capture technology pioneered by Carbon Clean. While the IRA involves billions of dollars of public investment, it is set up in such a way that companies must make substantial investments first, acting as a down payment on fostering jobs and ensuring the business community is delivering ambitious climate action. The benefits are being felt locally as well – cities like Houston are at the forefront of what the IRA has to offer, taking advantage of these investments and reducing emissions.

Companies and stakeholders across the energy spectrum need to act together and act fast. With the dramatic growth required for carbon capture to have full effect, it will be essential for government, industry, and innovators to join together to concentrate on a number of projects and clusters. We are confident that with new cutting-edge technology and broad collaboration we can rapidly get the world on the right path to net zero.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
