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

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.

“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.” Read more.

Texas ranks among the 5 best states to start a business in 2025

Best for Biz

As one of the largest states in the U.S., it's no surprise Texas is big on business and entrepreneurship. Now the state is earning new praise among WalletHub's 2025 list of "Best & Worst States to Start a Business."

The Lone Star State claimed the No. 4 spot in the report's rankings, proving that Texas is in a much better business shape than it was last year when it earned No. 8 in WalletHub's annual report.

The study compared all 50 states across 25 metrics to determine the best places to start, grow, and find success with a new business. Factors that were considered include the number of startups per capita, job growth rates, financing accessibility measures, labor costs and corporate tax rates.

The three states to outperform Texas in the 2025 report are Florida (No. 1), Georgia (No. 2), and Utah (No. 3). Idaho rounded out the top five.

Across the study's three main categories, Texas performed the best in the "business environment" category, earning No. 1 nationally. This section compares the states based on five-year business survival rates, average business revenues growth and more.

Texas ranked No. 12 in the nationwide comparison of "access to resources" – which covers working age population growth, venture investment amounts per capita and other means – and earned a fair No. 34 in the report's "business costs" ranking.

But Texas can still do better with its business friendliness to reclaim a top-three overall ranking, which the state last earned in 2023.

WalletHub analyst Chip Lupo said in the report that it is imperative for potential new business owners to establish their enterprise in a place that can maximize their ability to succeed.

"Around half of all new businesses don’t survive five years, so the idea of becoming a business owner can be daunting, especially with the current high cost of living," Lupo said. "The best states have low corporate tax rates, strong economies, an abundance of reliable workers, easy access to financing and affordable real estate. On top of that, you’ll need to make sure you start in a place with an engaged customer base, if you’re operating locally."

Houston has also proven to be at the top of the destination list for entrepreneurs who are looking for their next venture.

The top 10 best states to start a new business in 2025 are:

  • No. 1 – Florida
  • No. 2 – Georgia
  • No. 3 – Utah
  • No. 4 – Texas
  • No. 5 – Idaho
  • No. 6 – Oklahoma
  • No. 7 – Nevada
  • No. 8 – Colorado
  • No. 9 – Arizona
  • No. 10 – Kentucky

Play it back: Why this Houston geothermal innovator's company is set for a hot year of growth

houston innovators podcast Episode 271

Last year was one full of big wins for Fervo Energy and its CEO and co-founder, Tim Latimer. The company secured around $600 million in investment and financing across a few deals and is aiming for a 2026 delivery date of its next project.

Fervo Energy, which is built off of a unique horizontal well drilling technology, is currently scaling at around a 100x pace, as Latimer explained in May on the Houston Innovators Podcast, thanks to its latest project, Project Cape, located in Southwest Utah, that will include around 100 wells with significantly reduced drilling cost and an estimated 2026 delivery. Latimer says there are a dozen other projects like Project Cape that are in the works.

"It's a huge ramp up in our drilling, construction, and powerplant programs from our pilot project, but we've already had tremendous success there," Latimer says of Project Cape. "We think our technology has a really bright future."

Revisit the podcast episode below where Latimer talks about Fervo's fast growth and promising future.

Latimer has been bullish on geothermal as a clean energy source since he quit his job as a drilling engineer in oil and gas to pursue a dual degree program — MBA and master's in earth sciences — at Stanford University. He had decided that, with the reluctance of incumbent energy companies to try new technologies, he was going to figure out how to start his own company. Through the Stanford program and Activate, a nonprofit hardtech program that funded two years of Fervo's research and development, Latimer did just that.

"Every overnight success is a decade in the making, and I think Fervo, fortunately — and geothermal as a whole — has become much more high profile recently as people realize that it can be a tremendous solution to the challenges that our energy sector and climate are facing," he says on the Houston Innovators Podcast.

And the bet has more than paid off. In December, Fervo raised $255 million in new funding and capital availability. A $135 million corporate equity round was led by Capricorn’s Technology Impact Fund II and a $120 million letter of credit and term loan facility was granted by Mercuria, an independent energy and commodity group that previously invested in the company. Read more about the round.

In addition to the raise, Fervo also announced other exciting news since the episode aired, including being named among Time Magazine's top inventions of the year and expanding its partnership with Meta.

UH researchers develop breakthrough material to boost efficiency of sodium-ion batteries

eyes on clean energy

A research lab at the University of Houston has developed a new type of material for sodium-ion batteries that could make them more efficient and boost their energy performance.

Led by Pieremanuele Canepa, Robert Welch assistant professor of electrical and computer engineering at UH, the Canepa Research Laboratory is working on a new material called sodium vanadium phosphate, which improves sodium-ion battery performance by increasing the energy density. Energy density is the amount of energy stored per kilogram, and the new material can do so by more than 15 percent. With a higher energy density of 458 watt-hours per kilogram — compared to the 396 watt-hours per kilogram in older sodium-ion batteries — this material brings sodium technology closer to competing with lithium-ion batteries, according to the researchers.

The Canepa Lab used theoretical expertise and computational methods to discover new materials and molecules to help advance clean energy technologies. The team at UH worked with the research groups headed by French researchers Christian Masquelier and Laurence Croguennec from the Laboratoire de Reáctivité et de Chimie des Solides, which is a CNRS laboratory part of the Université de Picardie Jules Verne, in Amiens France, and the Institut de Chimie de la Matière Condensée de Bordeaux, Université de Bordeaux, Bordeaux, France for the experimental work on the project.

The researchers then created a battery prototype using the new materia sodium vanadium phosphate, which demonstrated energy storage improvements. The material is part of a group called “Na superionic conductors” or NaSICONs, which is made to let sodium ions move in and out of the battery during charging and discharging.

“The continuous voltage change is a key feature,” Canepa says in a news release. “It means the battery can perform more efficiently without compromising the electrode stability. That’s a game-changer for sodium-ion technology.”

The synthesis method used to create sodium vanadium phosphate may be applied to other materials with similar chemistries, which could create new opportunities for advanced energy storage. A paper of this work was published in the journal Nature Materials.

"Our goal is to find clean, sustainable solutions for energy storage," Canepa adds. "This material shows that sodium-ion batteries can meet the high-energy demands of modern technology while being cost-effective and environmentally friendly."
