In the 2019 State of the City Address hosted by the Greater Houston Partnership on May 20, Mayor Sylvester Turner took the stage at the Marriott Marquis in front of over 1,500 Houstonians.

Some of the obvious topics were of course on the table — pension reform, hurricane recovery, job growth — but Mayor Turner surprised attendees with the announcement of a public-private parks program and again alluded to the re-envisioned of Astroworld.

Here's what all the mayor promised in his address.

Public-private partnerships for Houston parks

Houston's major parks have undergone major transformations lately backed by private investments — Buffalo Bayou Park, Memorial Park Conservancy, and Bayou Greenways 2020, to name a few — but the city would like to shift focus to smaller, neighborhood parks across the city. To do this, Mayor Turner called for 50 companies to sponsor 50 parks.

"Today, I am asking the Greater Houston Partnership, the Houston Parks Board, and the Parks Department, to help me bring together 50 companies to form a citywide coalition for our neighborhood parks — primarily in underserved communities," Mayor Turner says.

Scott McClelland, president of HEB Food and Drug and board chair of the GHP, offered up HEB as a corporate partner for the program on the spot, despite the formal details of the program not yet being disclosed. Mayor Turner did specify that the park sponsorship would be a commitment over a few years.

"The 50 for 50 effort will touch every district in the city. All Houstonians should have easy access to welcoming, well-maintained, safe, and fun parks," he says.

A developed innovation corridor and a resurgence of AstroWorld

In both in his introductory address and fireside chat with McClelland, Mayor Turner talked about the emergence of Houston's innovation ecosystem. He cites the 140 percent increase in technology jobs as well as the 3,000 reported startups that call Houston their home. He mentions that Silicon Valley-based accelerator program Plug and Play is preparing to enter the market and another 25 million investment from the Houston Exponential fund of funds is expected.

"We're not walking; we're sprinting," Mayor Turner says. "There is no better place for an [innovation] ecosystem to take place than Houston."

Mayor Turner also credited Rice University's The Ion project as a major source of growth for the city's innovation ecosystem.

"We are building an innovation hub and corridor — in collaboration with academia, thank you, Rice, for loaning us the Sears building on South Main, and the energy and tech companies."

When discussing the innovation district, the mayor also gave a shout out to Travis Scott for being the "instigator" of a new AstroWorld-like theme park the city has in the works, but no details were disclosed in the address.

Rethinking Houston's transportation system

As Houston's population continues to grow, Houstonians spend more and more time in their cars fighting traffic. The mayor called for action to reimagine Houston's transportation.

"Our city has changed, the region is changing, and our transportation, transit, and mobility must change," he says. "People want options, and we must give them options."

Mayor Turner alluded to the Metro Next plan that will be on the ballot this November. While he didn't go into much detail, he encouraged support for the plan.

A raise for the Houston Fire Department

McClelland started the fireside chat with a question about the state of things after Proposition B's repeal following being deemed unconstitutional. The proposition, which originally passed last fall, would have matched Houston firefighters' salaries with police officers.

The mayor says that with the repeal, no layoffs or job cuts will be made within the Houston Fire Department. He recognizes that firefighters are in need of a raise, but it must be one the city can afford.

"Our firefighters are deserving of a pay raise," Mayor Turner says. "What I've put forth is 9.5 percent over three years, but look, my door is open."

The best is yet to come

Mayor Turner wrapped up his address on a positive note, saying that the city's growth will continue.

"The state of our city is strong, resilient, and sustainable," he says. "The best for us as a city has yet to come."

All of these initiatives on the mayor's agenda are working for toward uniting and enhancing Houston.

"We are building one complete city," he says. "And we work together, we win."

Rice University breaks ground on new innovation hub, The Arc

breaking ground

Construction is officially underway on Rice University's The Arc in Houston’s Ion District.

The university broke ground on the 200,000-square-foot research, corporate innovation and office building on Nov. 4. The facility will share a plaza with the existing Ion building, fostering collaboration within the innovation space, according to Rice.

“The Arc will bring Rice’s extraordinary research and talent and Houston’s impactful innovation ecosystem into even closer connection with the industries and innovators working to solve some of the world’s most consequential challenges,” Rice President Reginald DesRoches said in an announcement. “That constant exchange of ideas and expertise will help move discoveries more rapidly from the laboratory to real-world impact.”

Construction is scheduled to be completed by Q2 2028. Rice Real Estate Co. is developing the project, and Rice University will occupy about 80,000 square feet in the building (about 40 percent). Preleasing has begun, with floor plans ranging from 28,000 to 31,000 square feet.

The Arc will feature conference and meeting spaces, an amenity lounge, fitness center, outdoor plazas, underground parking, and on-site retail and dining, according to the release.

It aims to host tenants focused on artificial intelligence and machine learning, data science, robotics, quantum science and engineering and energy, including Rice's new AI Foundry.

Rice says the AI Foundry will be a space where university experts and partners can support organizations with AI challenges. Rice recently committed to hiring 75 new AI-focused faculty and announced plans to launch a new Master of Artificial Intelligence (MAI) next fall.

“The AI Foundry is exactly the kind of collaboration the Arc is designed to enable,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs at Rice, added in the release. “By bringing Rice researchers together with industry partners in a shared environment, we can accelerate the movement of ideas from research into practical applications while helping organizations build the capabilities they need to succeed as AI continues to evolve.

Developers of The Arc are targeting LEED Gold certification by incorporating smart building automation and energy-saving features into the project's design. Rice first announced the project in September 2025.

Houston battery tech startup FlowCellutions acquired by Katy energy co.

M&A

Katy-based TerraFlow Energy, an energy storage and infrastructure company, has acquired Houston-based battery technology startup FlowCellutions. Financial terms weren’t disclosed.

FlowCellutions still operates under its established name, but with the tagline “A TerraFlow Energy Company.” Becca Segel, founder and CEO of FlowCellutions, now runs the business as its president.

FlowCellutions specializes in electrochemical sensing, diagnostics, analytics, and testing that offer insights into battery chemistry, charging capabilities, and system performance.

“FlowCellutions has always been focused on developing better ways to understand what is happening inside a flow battery and using that information to improve how these systems perform,” Segal said in a press release. “Joining TerraFlow gives us the opportunity to apply that work at a much larger scale while continuing to build the capabilities and expertise that make FlowCellutions unique.”

The FlowCellutions platform supports data centers and other heavy users of power. It’s designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from about seven years to more than 30 years.

Segel founded the company in 2022. A member of Greentown Labs, the company raised more than $2 million in non-dilutive funding and received $1.5 million in National Science Foundation funding earlier this year.

FlowCellutions is one of five finalists in the Energy Transition Business category of InnovationMap’s 2026 Houston Innovation Awards.

“FlowCellutions brings a depth of scientific and technical expertise that fits naturally with where TerraFlow is going,” Jon Parrella, CEO of TerraFlow, said in the release.

“As we move from developing these systems to deploying them at commercial scale, understanding performance at a deeper level matters,” he said. “Bringing FlowCellutions into TerraFlow strengthens that capability and gives both teams more opportunity to advance the technology.”TerraFlow, founded in 2024, develops long-duration energy storage and power infrastructure for data centers, industrial facilities, utilities and other large power consumers.

As part of the 2026 Houston Innovation Awards, our Scaleup of the Year category honors innovative later-stage startups that have recently reached a significant milestone in company growth. Three scaleups have been named finalists for the 2026 award.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.
