The feeling is all too familiar for Houstonians. Tropical Storm Imelda hit Houston with devastating flood waters just two years after Hurricane Harvey did its damage.

With any obstacle or challenge, there is room for innovation. Over the past year, InnovationMap has covered various flood tech startups in Houston. Here are six innovations that can make a difference the next time a storm decides to take its toll on Houston.

Self-deploying flood protection for buildings

A self-deploying flood damage prevention device caught Tasha Nielsen's eye on a trip to Denmark, and then launched the U.S. iteration of FloodFrame to bring the technology here.

FloodFrame works by using buoyancy. A lightweight cloth is wrapped around a tube is installed underground outside the perimeter of your home or business. One end of that cloth is attached to a box that is also installed underground. As flooding begins, an automatic system will release the lids to deploy the inflation of the tube that will protect the structure. When the flood comes in, the system will float on top of the flood — kind of like a pool noodle — and protect the structure from the water.

FloodFrame adds a level of security during flooding events and can be considered more cost-effective when compared to the high cost of renovating or rebuilding after flooding.

"Right now we are focused on residential but I think there's a huge potential for it to go commercial. A lot of commercial buildings are self insured, and commercial developers, industrial developers, this would be a drop in the bucket for the overall cost of the entire project," Nielsen tells InnovationMap. "For homeowners, it's kind of a bigger expense, but I think there is the potential for homebuilders to include it as an option in the entire package of a new house because when you put it in to a mortgage, it's only another like $0.50 a month."

Floodwaters from Hurricane Harvey seriously damaged about 600,000 vehicles in the Houston area, which included Rahel Abraham's 2008 Infiniti G35. Now, Abraham's brainchild forms the backbone of her Houston-based startup, ClimaGuard LLC. The company's waterproof, temperature-resistant, portable Temporary Protective Enclosure (TPE) can entirely cover a compact car, sedan, or midsize SUV. It comes in three sizes; the cost ranges from $349 to $499.

To protect a vehicle, someone sets a TPE on the ground, a driveway, or another flat surface, then drives the vehicle onto the bottom part of the product, and connects the bottom and top parts with the zipper. Abraham likens it to a clamshell preserving a pearl.

"My goal is not to make it to where it's an exclusive product — available only to those who can afford it — but I want to be able to help those who it would make even more of an economic impact for," Abraham tells InnovationMap.

A network to find shelter.

It only took a natural disaster for Reda Hicks to make her startup idea into a reality.

"I had been thinking on what it would be like to help people find space to do business in and how businesses find a way to stay in business a long time," Hicks tells InnovationMap. "But, I was afraid of the tech."

Hicks, who has practiced law for almost 15 years, wanted to create a website that allows for people with commercial space — a commercial kitchen, conference room, spare desks, etc. — to list it. Then, space seekers — entrepreneurs, nonprofits, freelancers, etc. — can rent it. When Hurricane Harvey hit, Hicks was kicking herself for not acting on her idea sooner.

"It was really Harvey and having so many people desperate to find space for emergency purposes that made me realize there are so many contexts in which people need space right away for something specific," she says. "Certainly the primary user is the entrepreneur trying to grow their business, but there are so many other reasons why a community would need better access to the space it already has."

Now Hicks is growing GotSpot in hopes that short-term rental space and emergency housing can be smooth sailing no matter the circumstances. Recently, the company was named a finalist for MassChallenge Texas in Austin.

In the wake of Hurricane Harvey, many Houstonians began to think of solutions for the next time Mother Nature struck with her full-force of flooding. Gensler designers Chelsea Bryant, Jordan Gomez, Luisa Melendez, Barbara Novoa, Benjamin Nanson, Maria Qi, and Melinda Ubera created a solution as a part of Gensler's By Design program called Fil Trat. The tower can absorb, filter, and store flood waters until the bayou is ready for the water to be released — cleaner than it was before.

During Harvey, thousands of people were displaced, but Fil Trat has a solution for that too. The tower's floors would alternate between filtration floors and shelters, which could house up to 24 families per floor.

While the suggested Houston locale would be by Buffalo Bayou, the group suggests putting the tower in other coastal cities at risk of devastating flooding.

Nearly two years after Hurricane Harvey battered the Houston area, a flock of electronic "rubber ducks" flew above homes in Katy in a broader endeavor to keep first responders and victims connected during natural disasters.

Developers and backers of Project Owl, an Internet of Things (IoT) hardware and software combination, conducted a pilot test of this innovation June 1 — the first day of this year's hurricane season. In the Katy test, 36 "ducks" took flight.

"So, our technology can be deployed to help communities that have been destroyed after natural disasters by providing quickly accessible communications network to coordinate and organize a response," Bryan Knouse, co-founder and CEO of Project Owl, tells InnovationMap.

The DuckLink network comprises hubs resembling rubber ducks, which can float in flooded areas if needed. It takes only five of these hubs to cover one square mile. This network sends speech-based communications using conversational systems (like Alexa and Facebook Messenger) to a central application. The app, the Owl software incident management system, relies on predictive analytics and various data sources to build a dashboard for first responders.

Restored native wetland coastal prairies.

Before it was the fourth largest city in America, Houston was a prairie. That type of ecosystem — thick with prairie grass — is very absorbing when it comes to rain water. Cassidy Brown Johnson, a Rice University lecturer and president of the Coastal Prairie Partnership, has been taking every opportunity to raise awareness on the importance of prairie restoration.

"It's really surprising to people that the trees and all this lushness is actually all artificial," Johnson says. "We know that this ecosystem evolved with the cyclical flooding events that happened here."

This movement to bring back Houston's ancient ecosystem is a new focus on a few prairie conservationist groups — and even the Harris County Flood Control. This has been going on for a while, but recent flooding events have opened the eyes of people now looking for reliable solutions to flooding problems.

"After Hurricane Harvey, people started realizing that this might be one of the solutions we could actually investigate and see if it can help us," Johnson says. "A green space is going to absorb way more water than a parking lot."

Memorial Park Conservancy's master plan redevelopment project, which is being supported by the Kinder Foundation, includes a lot of prairie restoration plans is expected to deliver by 2028.

The project is a collaborative effort between MPC, Uptown Houston TIRZ, and Houston Parks, Kinder Foundation, and Recreation Department to redevelop the 1,500-acre park. An ongoing part of the transformation will be stormwater management upgrades. MPC has budgeted $3 million to this asset of the renovation. While a part of the plan is tributaries for run-off water, bringing back prairie and wetlands will do a great deal to help abate stormwater.

"We're taking ball fields, parking lots, and roads and converting them back to what was here — native wetland coastal prairie," MPC president and CEO Shellye Arnold tells InnovationMap. "This serves important stormwater purposes."

Houston researchers make headway on affordable, sustainable sodium-ion battery

Energy Solutions

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”

FAA demands investigation into SpaceX's out-of-control Starship flight

Out of this world

The Federal Aviation Administration is demanding an accident investigation into the out-of-control Starship flight by SpaceX on May 27.

Tuesday's test flight from Texas lasted longer than the previous two failed demos of the world's biggest and most powerful rocket, which ended in flames over the Atlantic. The latest spacecraft made it halfway around the world to the Indian Ocean, but not before going into a spin and breaking apart.

The FAA said Friday that no injuries or public damage were reported.

The first-stage booster — recycled from an earlier flight — also burst apart while descending over the Gulf of Mexico. But that was the result of deliberately extreme testing approved by the FAA in advance.

All wreckage from both sections of the 403-foot (123-meter) rocket came down within the designated hazard zones, according to the FAA.

The FAA will oversee SpaceX's investigation, which is required before another Starship can launch.

CEO Elon Musk said he wants to pick up the pace of Starship test flights, with the ultimate goal of launching them to Mars. NASA needs Starship as the means of landing astronauts on the moon in the next few years.

TMC med-tech company closes $2.5M series A, plans expansion

fresh funding

Insight Surgery, a United Kingdom-based startup that specializes in surgical technology, has raised $2.5 million in a series A round led by New York City-based life sciences investor Nodenza Venture Partners. The company launched its U.S. business in 2023 with the opening of a cleanroom manufacturing facility at Houston’s Texas Medical Center.

The startup says the investment comes on the heels of the U.S. Food and Drug Administration (FDA) granting clearance to the company’s surgical guides for orthopedic surgery. Insight says the fresh capital will support its U.S. expansion, including one new manufacturing facility at an East Coast hospital and another at a West Coast hospital.

Insight says the investment “will provide surgeons with rapid access to sophisticated tools that improve patient outcomes, reduce risk, and expedite recovery.”

Insight’s proprietary digital platform, EmbedMed, digitizes the surgical planning process and allows the rapid design and manufacturing of patient-specific guides for orthopedic surgery.

“Our mission is to make advanced surgical planning tools accessible and scalable across the U.S. healthcare system,” Insight CEO Henry Pinchbeck said in a news release. “This investment allows us to accelerate our plan to enable every orthopedic surgeon in the U.S. to have easy access to personalized surgical devices within surgically meaningful timelines.”

Ross Morton, managing Partner at Nodenza, says Insight’s “disruptive” technology may enable the company to become “the leader in the personalized surgery market.”

The startup recently entered a strategic partnership with Ricoh USA, a provider of information management and digital services for businesses. It also has forged partnerships with the Hospital for Special Surgery in New York City, University of Chicago Medicine, University of Florida Health and UAB Medicine in Birmingham, Alabama.
