Houston cleantech startup Helix Earth lands $1.2M NSF grant

federal funding

Renewable equipment manufacturer Helix Earth Technologies is one of three Houston-based companies to secure federal funding through the Small Business Innovation Research (SBIR) Phase II grant program in recent months.

The company—which was founded based on NASA technology, spun out of Rice University and has been incubated at Greentown Labs—has received approximately $1.2 million from the National Science Foundation to develop its high-efficiency retrofit dehumidification systems that aim to reduce the energy consumption of commercial AC units. The company reports that its technology has the potential to cut AC energy use by up to 50 percent.

"This award validates our vision and propels our impact forward with valuable research funding and the prestige of the NSF stamp of approval," Rawand Rasheed, Helix CEO and founder, shared in a LinkedIn post. "This award is a reflection our exceptional team's grit, expertise, and collaborative spirit ... This is just the beginning as we continue pushing for a sustainable future."

Two other Houston-area companies also landed $1.2 million in NSF SBIR Phase II funding during the same period:

  • Resilitix Intelligence, a disaster AI startup that was founded shortly after Hurricane Harvey, that works to "reduce the human and economic toll of disasters" by providing local and state organizations and emergency response teams with near-real-time, AI-driven insights to improve response speed, save lives and accelerate recovery
  • Conroe-based Fluxworks Inc., founded in 2021 at Texas A&M, which provides magnetic gear technology for the space industry that has the potential to significantly enhance in-space manufacturing and unlock new capabilities for industries by allowing advanced research and manufacturing in microgravity

The three grants officially rolled out in early September 2025 and are expected to run through August 2027, according to the NSF. The SBIR Phase II grants support in-depth research and development of ideas that showed potential for commercialization after receiving Phase I grants from government agencies.

However, congressional authority for the program, often called "America's seed fund," expired on September 30, 2025, and has stalled since the recent government shutdown. Government agencies cannot issue new grants until Congress agrees on a path forward. According to SBIR.gov, "if no further action is taken by Congress, federal agencies may not be able to award funding under SBIR/STTR programs and SBIR/STTR solicitations may be delayed, cancelled, or rescinded."

Houston clean-tech co. with NASA ties wins big at SXSW 2025

And the winner is...

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.

2 sustainability-focused student startups named to Houston accelerator

ready to grow

Rice University's Liu Idea Lab for Innovation & Entrepreneurship, or Lilie, has named eight teams to the second cohort of the Lilie Summer Venture Studio, and two have sustainability as a goal.

According to Rice, the 12-week program received a record number of applications, that spanned the campus' degree offerings.

“We are thrilled to see such a high level of interest and excitement from Rice students for a high-growth venture accelerator,” Kyle Judah, executive director of Lilie, said in a statement. “The diversity and creativity in this year's applications were truly inspiring, and we’re excited to support these promising ventures with the resources and mentorship they need to hit escape velocity and create the next generation of pillar companies for Houston, Texas and the world.”

The selected teams will receive $15,000 in non-dilutive funding from the accelerator, along with access to coworking space and personalized mentorship in the Liu Idea Lab.

Coflux Purification, a patent-pending in-stream module that breaks down PFAS using a novel absorbent for chemical-free water, was named to the cohort, as was Solidec, a technology platform that extracts molecules from water and air, transforms them into pure chemicals and fuels without any carbon emissions.

Here are the rest of the teams for the 2024 Lilie Summer Venture Studio:

  • Docflow, focused on streamlining residency shift scheduling
  • JewelVision, building virtual fitting rooms for jewelry e-commerce retailers using generative AI
  • Levytation, using data science and AI to answer critical questions about sales and customers for coffee shop management
  • OnGuard, a marketplace to book off-duty police officers and security professionals
  • Roster, leverages data on athletes in the NCAA Transfer Portal to automatically send updates on players to coaches
  • Veloci, a running shoe venture that addresses common pains through shoe design

Lilie launched the Summer Venture Studio last year. According to Rice, two out of the six teams selected, Helix Earth Technologies and Tierra Climate, which both also tackle sustainability challenges, raised venture capital funds after completing the accelerator program.

Helix Earth Technologies also went on to earn the inaugural TEX-E Prize at CERAWeek in 2023.

“The track record of our Summer Venture Studio Accelerator speaks for itself, despite being early in our second year," Taylor Anne Adams, head of venture acceleration programs at the Liu Idea Lab, said in a statement. "This is the power of entrepreneurship programming that is designed by founders, for founders, that happens at the Liu Idea Lab.”

Last year, Lilie also named 11 successful business leaders with ties to Houston to its first Lilie’s Leadership Council. Each agreed to donate time and money to the university’s entrepreneurship programs.

Oxy CEO Vicki Hollub to retire, Reuters reports

retirement plans

Vicki Hollub, CEO of Houston-based Occidental (Oxy), is set to retire this year, Reuters first reported Thursday.

Hollub has held the top leadership position at Oxy since 2016 and has been with the oil and gas giant for more than 40 years. Before being named CEO, she served as chief operating officer and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Reuters reports that a firm date for her retirement has not been set. Richard Jackson, who currently serves as Oxy's COO, is expected to replace Hollub in the CEO role.

Oxy is leading a number of energy transition projects.

It's subsidiary 1PointFive is developing a $1.3 billion direct air capture (DAC) project in the Midland-Odessa area that is slated to be the largest facility of its kind in the world. Known as STRATOS, it's designed to capture up to 500,000 metric tons of CO2 per year.

The company shared recently that Phase 1 of the project is expected to go online in Q2, with Phase 2 ramping up through the remainder of 2026.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos last year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” she added.

Oxy was one of the first to set ambitious net-zero goals. In a 2020 interview during CERAWeek, Hollub outlined Oxy's future as a “carbon management company.”

“Ultimately, I don’t know how many years from now, Occidental becomes a carbon management company, and our oil and gas would be a support business unit for the management of that carbon. We would be not only using [CO2] in oil reservoirs [but] capturing it for sequestration as well,” Hollub said.

Oxy opened its Oxy Innovation Center in the Ion last year, focused on advancing low-carbon technology. It also operates Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others.

Hertha Metals named world's  No. 1 most innovative manufacturing co. of 2026

top innovators

Led by Conroe-based Hertha Metals, five organizations in the Houston area earned shoutouts on Fast Company’s list of the World’s Most Innovative Companies of 2026.

Hertha Metals ranked No. 1 in the manufacturing category.

Last year, Hertha unveiled a single-step process for steelmaking that it says is cheaper, more energy-efficient and just as scalable as traditional steel manufacturing. It started testing the process in 2024 at a one-metric-ton-per-day pilot plant.

At the same time, Hertha announced more than $17 million in venture capital funding from investors such as Breakthrough Energy, Clean Energy Ventures, Khosla Ventures, and Pear VC.

“We’re not just reinventing steelmaking; we’re redefining what’s possible in materials, manufacturing, and national resilience,” Laureen Meroueh, founder and CEO of Hertha, said at the time.

Meroueh was also recently named to Inc. Magazine's 2026 Female Founders 500 list.

Hertha, founded in 2022, says traditional steelmaking relies on an outdated, coal-based multistep process that is costly, and contributes up to 9 percent of industrial energy use and 10 percent of global carbon emissions.

By contrast, Hertha’s method converts low-grade iron ore into molten steel or high-purity iron in one step. The company says its process is 30 percent more energy-efficient than traditional steelmaking and costs less than producing steel in China.

Last year, Hertha said it planned to break ground in 2026 on a plant capable of producing more than 9,000 metric tons of steel per year. In its next phase, the company plans to operate at 500,000 metric tons of steel production per year.

Here are Fast Company’s rankings for the four other Houston-area organizations:

  • Houston-based Vaulted Deep, No. 3 in catchall “other” category.
  • XGS Energy, No. 7 in the energy category. XGS’ proprietary solid-state geothermal system uses thermally conductive materials to deliver affordable energy anywhere hot rock is located. While Fast Company lists Houston as XGS’ headquarters, and the company has a major presence in the city, XGS is based in Palo Alto, California.
  • Houston-based residential real estate brokerage Epique Realty, No. 10 in the business services category. Epique, which bills itself as the industry’s first AI brokerage, provides a free AI toolkit for real estate agents to enhance marketing, streamline content creation, and improve engagement with clients and prospects.
  • Texas A&M University’s Nanostructured Materials Lab in College Station. The lab studies nano-structured materials to make materials lighter for the aerospace industry, improve energy storage, and enable the creation of “smart” textiles.
