HISD receives millions in funding from EPA for clean school buses

Houston Independent School District is hopping on the city's net-zero carbon emissions bus, so to speak, thanks to more than $6.2 million in funding that came from the Environmental Protection Agency last year.

The funds are part of the EPA's Clean School Bus Program Fiscal Year 2022 rebate competition, which will award nearly $51 million in funds from President Biden’s Bipartisan Infrastructure Law to Texas school districts, and $965 million in total to districts around the country.

Houston's $6.2 million will go toward 25 new school buses, according to a statement from the EPA. Fifteen of the vehicles will be brand-new electric buses.

"Taking steps to make our school buses greener while remaining safe and effective is not only imperative for the wellbeing of students and bus drivers, but also for the public at large,” Houston Congressman Al Green said in a statement. “I applaud this announcement by the EPA under President Biden’s leadership. I look forward to seeing the positive impact that this outstanding award to purchase electric and propane school buses will have on reducing our carbon footprint.”

HISD's next step was to submit Payment Request Forms with purchase orders that shows the district has ordered the new buses and eligible infrastructure.

The district is among 13 Texas school districts to receive funding. Dallas ISD, the second largest school district in the state behind HISD, was awarded roughly $7.6 million. Killeen ISD and Socorro ISD received the largest sums among the districts, totalling nearly $9.9 million in funding each.

At the time of the statement from October, the EPA had selected 389 applications across the country totaling $913 million to support the purchase of 2,463 buses, mainly in areas serving low-income, rural, and/or Tribal students. More applications are under review, and the EPA plans to announce additional districts that will receive funding, bringing the total investment to the full $965 million, in the coming weeks, according to a statement.

The EPA intends to make available another $1 billion for clean school buses in Fiscal Year 2023.

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."
