SafePass is a reusable visitor pass for large campuses — corporate, schools, oil and gas, etc. — that need a digital system to protect both the campus and the visitor. Photo via safepassglobal.com

There's an only public service announcement from the 1960s that asks, "It's 10:00 p.m., do you know where your children are?" The idea behind it was to encourage parents to ensure their children's safety, by encouraging them to be home before what was then the youth curfew in several states.

"Do you know where your visitors are right now?" asks the SafePass website, providing an answer: "You do if you have SafePass."

The visitor management system is the brainchild of Ronald Huff, who initially envisioned the system as a hall pass for students. The electronic pass would monitor students in real time, if they left class to go to the nurse or the restroom, meaning adults would be able to find them in the event of an emergency. But as Huff and his business partners proceeded through product development, they realized SafePass had a stronger lure as a system that could manage visitors across several platforms – business, schools, and secure environments.

The system works like this: companies issue a SafePass visitor badge to visitors, contractors or others who are temporarily on the grounds of their facilities. The badge records signal strengths from WiFi routers set up around the facility and tracks where the visitor is in real time.

"Visitors don't know a facility as well as the people who work there every day do," said Huff. "If there's smoke or a fire, they might get lost. So, SafePass helps provide a record of where they are, meaning that people can find them if there's an emergency or an evacuation."

SafePass is also reusable. The electronic badge is designed to be used over and over again, unlike common printed paper badges that visitors stick on.

"We're 100 percent eco-friendly," said Huff.

He and his partners built the demo for the product at the end of 2017 and began shopping it at trade shows. The reaction was immediate, with multiple companies wanting to take on the system. SafePass is about to launch a pilot phase with some Fortune 100 companies, and has plans to expand soon beyond that.

Companies can currently email their floor plans to SafePass, which creates routes within the floor plans, fixing geolocations. Then the signal strength from WiFi routers is digitally mapped within the building using an Android app. This allows the electronic badge to know where a guest is as he or she is traveling throughout a given facility.

"I think most people know that cell phones record almost everything we do," said Huff, explaining that SafePass isn't designed to infringe on personal privacy. "This isn't a Big Brother situation. Above all else, we're concerned about the safety of both people who are visiting a facility and those who work there every day."

Huff said SafePass can also help companies with safety and security compliance. For instance, oil and gas companies are audited by third parties on how secure their facilities are. SafePass' technology helps them not only score higher on an audit, but actually keep their facilities secure.

"A product like ours solves so many different problems," he said.

After nearly two and half years of development, Huff said he's excited about what's to come.

"This is really my baby," he said of the company. "And it's been such a blessing to work with this team of developers and programmers and sales people. We've got a great team and great clients. This is a dream come true."

SafePass has made a splash on the Houston digital innovation scene and was even named one of the most promising startups at the recent Texas Digital Summit.

NASA signs on latest tenant for new Exploration Park campus, now underway

space hub

Exploration Park, the 240-acre research and commercial institute at NASA's Johnson Space Center, is ready for launch.

Facilities at the property have broken ground, according to a recent episode of NASA's Houston We Have a Podcast, with a completion date targeted for Q4 2026.

The research park has also added Houston-based KBR to its list of tenants. According to a news release from the Greater Houston Partnership, the human spaceflight and aerospace services company will operate a 45,000-square-foot food innovation lab at Exploration Park. KBR will use the facility to focus on customized food systems, packaging and nutrition for the low Earth orbit economy.

“Exploration Park is designed for companies in the space ecosystem, such as KBR, to develop, produce, and deploy innovative new technologies that support space exploration and commerce,” Simon Shewmaker, head of development at ACMI Properties, the developer behind Exploration Park, said in the GHP release. “This project is moving expeditiously, and we’re thrilled to sign such an innovative partner in KBR, reflecting our shared commitment to building the essential infrastructure of tomorrow for the next generation of space innovators and explorers.”

NASA introduced the concept of a collaborative hub for academic, commercial and international partners focused on spaceflight in 2023. It signed leases with the American Center for Manufacturing and Innovation and the Texas A&M University System for the previously unused space at JSC last year.

“For more than 60 years, NASA Johnson has been the hub of human space exploration,” Vanessa Wyche, NASA Johnson Space Center Director, said in a statement at the time. “This Space Systems Campus will be a significant component within our objectives for a robust and durable space economy that will benefit not only the nation’s efforts to explore the Moon, Mars and the asteroids, but all of humanity as the benefits of space exploration research roll home to Earth.”

Texas A&M is developing the $200 million Texas A&M Space Institute, funded by the Texas Space Commission, at the center of the park. The facility broke ground last year and will focus on academic, government and commercial collaboration, as well as workforce training programs. ACMI is developing the facilities at Exploration Park.

Once completed, Exploration Park is expected to feature at least 20 build-to-suit facilities over at least 1.5 million square feet. It will offer research and development space, laboratories, clean rooms, office space and light manufacturing capabilities for the aerospace, robotics, life support systems, advanced manufacturing and artificial intelligence industries.

According to the GHP, Griffin Partners has also been selected to serve as the co-developer of Exploration Park. Gensler is leading the design and Walter P Moore is overseeing civil engineering.

Houston cleantech co. plans first-of-its-kind sustainable aviation fuel facility

coming soon

Houston-based Syzygy Plasmonics announced plans to develop what it calls the world's first electrified facility to convert biogas into sustainable aviation fuel (SAF).

The facility, known as NovaSAF 1, will be located in Durazno, Uruguay. It is expected to produce over 350,000 gallons of SAF annually, which would be considered “a breakthrough in cost-effective, scalable clean fuel,” according to the company.

"This is more than just a SAF plant; it's a new model for biogas economics," Trevor Best, CEO of Syzygy Plasmonics, said in a news release. "We're unlocking a global asset class of underutilized biogas sites and turning them into high-value clean fuel hubs without pipelines, costly gas separation, or subsidy dependence.”

The project is backed by long-term feedstock and site agreements with one of Uruguay's largest dairy and agri-energy operations, Estancias del Lago, while the permitting and equipment sourcing are ongoing alongside front-end engineering work led by Kent.

Syzygy says the project will result in a 50 percent higher SAF yield than conventional thermal biogas reforming pathways and will utilize both methane and CO2 naturally found in biogas as feedstocks, eliminating the need for expensive CO2 separation technologies and infrastructure. Additionally, the modular facility will be designed for easy replication in biogas-rich regions.

The new facility is expected to begin commercial operations in Q1 2027 and produce SAF with at least an 80 percent reduction in carbon intensity compared to Jet A fuel. The company says that once fully commercialized the facility will produce SAF at Jet-A fuel cost parity.

“We believe NovaSAF represents one of the few viable pathways to producing SAF at jet parity and successfully decarbonizing air travel,” Best added in the release.
