With retail e-commerce sales in the U.S. projected to soar from $501 billion in 2018 to $740 billion in 2023, it's no wonder that Houston's industrial market is expanding faster than Santa's bag of toys.

E-commerce is one of the main drivers of an upturn in industrial construction in the Houston area. Estimates from four commercial real estate services companies show that during the third quarter, anywhere from 13.3 million square feet to 18.5 million square feet of industrial space was under construction in the region. That volume is up considerably from the second quarter of 2019 and from the same period in 2018.

Around the country, the "need for speed and choice" to appease shoppers is driving a lot of the increased demand for industrial space, Hamid Moghadam, chairman and CEO of industrial REIT Prologis, recently told Wall Street analysts. That, he said, is because "the more choices you want and the quicker you want them, the more inventory you need to position near the customers."

Rob Stillwell, executive managing director in the Houston office of commercial real estate services company Newmark Knight Frank, says many of the local industrial facilities geared toward e-commerce are being built in and around pockets of residential growth. This includes a swath from I-10 West in Katy to I-45 North toward The Woodlands. Among the facilities popping up in that corridor are massive projects for Amazon, FedEx, and UPS, according to Stilwell.

"E-commerce is likely a contributing factor to many distribution operations in Houston, but not the sole reason for the strong demand seen in the market," Stilwell says. Many new or expanding industrial tenants in the market do have an e-commerce component, he adds, yet won't be leasing space just for e-commerce purposes.

In Houston, e-commerce-fueled construction of industrial space is especially prevalent near George Bush Intercontinental Airport, according to commercial real estate services company Cushman & Wakefield. However, Houston's northwest submarket is seeing the most industrial construction in the area, with 5.5 million square feet underway in the third quarter.

Commercial real estate services company JLL pegs the southeast submarket as the hottest, with its third-quarter report showing 3.5 million square feet of new industrial projects underway there.

Aside from e-commerce, the Port of Houston and the petrochemical sector are propelling industrial construction in the area, Cushman & Wakefield says.

Around the Houston area, nine of the 89 industrial spaces under construction in the third quarter exceeded 500,000 square feet, Cushman & Wakefield says. Several of those lack a specific e-commerce element. This includes a 1 million-million-square-foot manufacturing facility for Coca-Cola, a more than 770,000-square-foot distribution center for Home Depot, and a nearly 550,000-square-foot distribution center for Costco.

Cushman & Wakefield warns that Houston's industrial market could suffer from an oversupply of space, as well as from a drop in shipping activity prompted by ongoing trade disputes and a decline in oil prices. Although industrial vacancy is expected to rise slightly through 2021, the company says, "demand continues for more modern, state-of-the-art facilities and market fundamentals remain healthy."

During the third quarter, only one-fourth of the space under construction in the Houston area was preleased, according to commercial real estate services company Colliers International. However, another 10 percent to 25 percent of that inventory should be preleased before the facilities are completed, the company says.

The area's industrial vacancy rate rose to 7.7 percent in the third quarter as new projects came online, Cushman & Wakefield says. Once more supply arrives, the vacancy rate is expected to tick up.

"Low interest rates and robust investor demand are expected to continue generating strong interest for Houston industrial assets. On the fundamentals side, the market is closely watching new inventory additions," JLL says.

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.”
