Houston had a strong showing at the 2025 SXSW Pitch showcase in Austin, with two local startups claiming top prizes, including a novel clean-tech startup.

Clean-tech company Helix Earth, which spun out of Rice University and was incubated at Greentown Labs, won in the Smart Cities, Transportation & Sustainability contest.

"We faced impressive competition from a well-chosen set of finalists, and we're honored to be chosen as the winners. One of the judges even commented, ‘Who knew you could make air conditioning sexy,’” Brad Husick, Helix's co-founder and chief business officer, said in a release.

Helix Earth was launched in 2022 and is known for its space capsule air filtration system that was co-developed for NASA. The commercial air conditioner add-on technology, now in a pilot phase, has been used to retrofit HVAC systems for commercial buildings and can save up to 50 percent of the net energy, cutting down on emissions and operating costs, according to the company. Its co-founder and CEO Rawand Rasheed was named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.

“This win validates our mission to drive sustainable innovation in commercial air conditioning and beyond. We are excited about the future of Helix Earth and the impact we will have in reducing energy consumption and emissions," Rasheed said in a statement.

Little Place Labs, a Houston space data startup, also walked away a winner in the Security, GovTech & Space competition. The company uses advanced AI and machine learning to deliver near-real-time space analytics for both ground and space-based applications. Its software aims to help first responders, mission planners and decision-makers detect anomalies and make informed decisions quickly. It was co-founded in 2020 at Oxford by Houstonian and CEO Bosco Lai and Gaurav Bajaj and participated in the 2023 AWS Space Accelerator.

"This all started with a simple mission: To deliver real-time space insights to help first responders, mission planners, and decision-makers act before problems arise,” Little Place Labs wrote on LinkedIn. "Today, that mission feels even stronger."

One of SWSX's marquee events, the pitch competition, held March 8-10, featured 45 finalists, selected from 589 applicants, in nine categories.

Two other Houston companies were finalists this year:
  • Trez, a Latino-focused fintech company that uses AI and voice-command payroll through WhatsApp to provide culturally relevant payroll and streamline financial operations for Latino business owners.
  • Tempesst Droneworx, a veteran-owned software company that's Harbinger software providing real-time contextual intelligence for early warning detection, reducing time to decision and speeding time to action.

Jesse Martinez, founder of invincible, and Anu Puvvada of KPMG were two judges representing Houston.

According to SXSW, 647 companies have participated in SXSW Pitch over the years, with over 93 percent receiving funding and acquisitions totaling nearly $23.2 billion. See the full list of 2025 winners here.

Experts address Houston's energy transition role — from research to commercialization

HOUSTON @ SXSW

Every part of the energy industry is going to have a role in the energy transition — from the universities where the research and development is happening to the startups and the incumbent industry leaders, as a recent SXSW panel discussed.

“We are well known in Houston for being the energy capital of the world," Jane Stricker, executive director of the Houston Energy Transition Initiative, says as moderator of the panel. "The industry typically comes together with stakeholders to think about the solutions and how to solve this dual challenge of continuing to provide more energy to the world but doing it in a way that significantly reduces emissions at the same time.”

The panel, entitled "Ground Zero: Creating Pathways from Research to Scale Deployment," was put on by HETI, an organization under the Greater Houston Partnership, and took place Sunday, March 12, in Austin at SXSW.

“I often say that I believe Houston is ground zero for the transition because we have this unique combination of assets, infrastructure, innovation, research at universities, and a collective understanding of the importance of energy to people’s lives that allows us to tackle this problem in new ways," she continues.

Sticker was joined by Paul Cherukuri, vice president for innovation at Rice University; Juliana Garaizar, chief development and investment officer at Greentown Labs; and Tara Karimi, co-founder and CTO of Cemvita Factory. The panel highlighted the challenges facing Houston as it promises to lead the energy transition.

For Cherukuri, whose innovation-focused position was newly created when he was appointed to it last August, it's a pivotal moment for research institutions.

"It's really an exciting time in Houston because universities are changing," says Cherukuri. "Rice University itself is changing in dramatic ways, and it's a great opportunity to really plug into the energy transition inside of Houston."

The role he plays, as he explains, is to connect Rice innovators to the rest of the city and the world.

"We have to partner through the accelerators as well as with with companies who can catch what we've made and take it to scale," he continues. "That's uniquely something that we can do in Houston. It's not something that a lot of cities can do."

Representing the scaling efforts is Greentown Labs, and Garaizar explains how the Massachusetts-based organization, which has its second outpost in Houston, connects its member companies to corporate partners that can become funders, pilot partners, customers, and more. But scaling can only be accomplished with the right technologies and the proper funding behind them.

"Sixty percent of the technologies that are going to be used to decarbonize the world haven't yet been invented," she says on the panel. "So, there's a huge pull for technology right now. And we see people who are only on the private equity space now finally invested in a lot of earlier series like series A, but there's still some road to to be made there."

Houston-based Cemvita Factory is in the scale phase, and Karimi explains how she's actively working with companies to apply the company's unique biotechnology to convert CO2 to natural resources to accommodate each customer's needs. Cemvita is on the front lines of interacting with incumbent energy businesses that play a major role in the future of energy.

"The way we communicate with energy companies, we tell them that us to be the innovation arm for you and we work together," Karimi says. "I think it's everybody needs to understand it's a transition. There is no way to just change the way that chemicals are produced just immediately and replace it with something new. It's a transition that needs both aspects."

Lithium refiner expands into Houston with new Energy Corridor office

new to hou

Battery-grade lithium carbonate manufacturer Stardust Power has expanded into Houston’s Energy Corridor, the company tells Energy Capital.

The company’s new office will serve as a project execution hub to support operations and planning for the company’s forthcoming lithium refinery in Muskogee, Oklahoma, according to a news release. The Greenwich, Connecticut-based, publicly traded company says the facility will be one of the largest lithium refining operations in the United States. The refinery is expected to have production capacity of up to 50,000 metric tons per year and seeks to address the critical shortage of U.S. lithium refining capacity.

Battery-grade lithium carbonate is commonly used in electric vehicle batteries and energy storage systems.

The company says it chose Houston as the location for its new execution hub for its rich history of expertise in engineering, a robust energy infrastructure ecosystem, and access to a leading talent pool for engineering, procurement and construction professionals. The Houston project hub will work closely with the company’s existing office in Oklahoma City.

“The Houston office strengthens our operational footprint at a critical phase of development,” Chris Celano, COO of Stardust Power, said in the release. “By building out a dedicated project management hub in one of the most experienced energy markets in the world, we are positioning the Company for execution as we advance the Muskogee refinery.”

Currently, the Houston office plans to accommodate a workforce of about 20 people with the possibility to add staff upon reaching project milestones, according to a representative from the company.

“This expansion reflects our commitment to deliver domestic, battery-grade lithium that supports U.S. energy security and industrial growth,” Celano added in the release.

In August, Stardust Power secured an offtake agreement to supply up to 20,000 metric tons of battery-grade lithium carbonate by 2030 from the Muskogee, Oklahoma, refinery to New York-based battery technology company Charge CCCV. Stardust reports that the deal adds to a separate non-binding agreement for up to 25,000 metric tons annually for 10 years with an undisclosed global trading company.

European cleantech company breaks ground on Houston manufacturing site

coming soon

Spanish renewable energy company Power Electronics broke ground on its new 53-acre Houston campus on Sept.24.

The new site is expected to create over 400 local jobs and deliver 40 gigawatts of production capacity per year. The company said in a news release that the campus is expected to be the largest manufacturing site for power conversion systems in the U.S. Power Electronics specializes in solar, energy storage, data centers and electrification technologies.

A completion date and operational start date have not yet been announced.

“For the first time in many years, the United States will be able to meet its growing need for sustainable power generation capacity and energy resilience through local manufacturing, supported by the most advanced technology in the world,” David Salvo, CEO of Power Electronics, said in the news release. “Our [40-gigawatt] Houston Campus will help shape the future of energy and AI growth globally."

Once operational, the manufacturing site will feature two buildings of approximately 150,000 square feet and 700,000 square feet. They will house production, logistics, R&D, corporate offices, training and electronic manufacturing departments.

The company says the Houston campus will be its most automated inverter production site by using advanced technologies in production to streamline day-to-day processes. Inverters convert direct current (DC) electricity that is generated by solar panels and batteries to alternating current (AC) electricity used by electrical grids.

Power Electronics' global headquarters is in Valencia, Spain, with U.S. operations in Houston, Tampa, and Gilbert, Arizona. Its North American headquarters is located at its existing North Houston office on East Airtex Drive. Community Impact News reports that the new manufacturing site is located in the Cy-Fair/Jersey Village area.

Power Electronics shared on LinkedIn that the new Houston campus represents its commitment to its American business and will allow it to serve the market with "greater scale, proximity and local expertise." It currently has more than 116 gigawatts installed in the U.S. and is working toward a global goal of 105 gigawatts of annual global production capacity.

Major oil exporters agree to keep production steady in November 2026

Oil News

Seven major oil-exporting countries agreed Sunday to keep production steady in November at a time when the Iran war has driven the price of benchmark Brent crude oil above $100 a barrel.

The so-called OPEC+ subgroup — Saudi Arabia, Russia, Iraq, Kuwait, Kazakhstan, Algeria and Oman — will meet again on November 1 to review conditions in the oil market.

The fighting with Iran, which began with U.S. and Israeli attacks on Feb. 28, has disrupted global oil supplies and driven prices higher.

The group of seven wealthy democracies said Friday that they plan to release 100 million barrels of oil and fuel products in the coming weeks, starting with “substantial” amounts of diesel.

Diesel prices recently hit record highs in the United States, squeezing farmers, truckers and consumers who depend on the fuel.

The G7 promised a “frontloaded substantial release” of diesel within the next 20 days and the rest over four months.
