Houston-based cleantech company 1PointFive is among the recipients of e-commerce giant Amazon’s first investments in carbon-fighting direct air capture (DAC).

Amazon has agreed to buy 250,000 metric tons of carbon removal credits from Stratos, 1PointFive’s first DAC plant, over a 10-year span. That commitment is equivalent to the amount of carbon stored naturally across more than 290,000 acres of U.S. forecasts, says Amazon.

Financial terms of the deal weren’t disclosed.

1PointFive is a carbon capture, utilization, and sequestration (CCUS) subsidiary of Houston-based energy company Occidental Petroleum.

The carbon captured for Amazon will be stored deep underground in saline aquifers — large geological rock formations that are saturated in saltwater.

As Amazon explains, DAC technology filters CO2 from the atmosphere and stores it in underground geological formations. Aside from being stored, removed carbon can be used to make building materials like bricks, cement, and concrete.

1PointFive is constructing its first DAC plant in Ector County, which is anchored by Odessa. The facility is expected to be the world’s largest DAC plant, capturing up to 500,000 tons of CO2 per year. Amazon Web Services (AWS) will provide real-time performance data for the plant.

“Amazon’s purchase and long-term contract represent a significant commitment to direct air capture as a vital carbon removal solution,” Michael Avery, president and general manager of 1PointFive, says in a news release. “We are excited to collaborate with Amazon to help them achieve their sustainability goals.”

1PointFive broke ground on the Stratos plant in April. Its project partners include British Columbia-based Carbon Engineering and Australia-based Worley. The plant is expected to be fully operational by mid-2025.

1PointFive envisions establishing more than 100 DAC facilities around the world by 2035.

The Amazon deal isn’t the only major deal for 1Point5 this summer.

In August, the U.S. Department of Energy (DOE) announced a $600 million grant for a 1PointFive-operated DAC hub that will be built in South Texas. The more than 100,000-acre hub, comprising 30 individual DAC projects, eventually may remove and store up to 30 million metric tons of CO2 per year.

Also in August, Japan’s All Nippon Airways (ANA) said it reached an agreement with 1PointFive to buy 10,000 metric tons of carbon removal credits per year over a three-year period starting in 2025. The credits will be generated by 1PointFive’s Stratos plant.

In the U.S., DAC has gotten a huge boost from the federal government. The Inflation Reduction Act, passed in 2022, includes tax credits for capturing and storing carbon via DAC.

The International Energy Agency says 27 DAC plants have been commissioned around the world, with at least 130 more in the development stage. One forecast predicts the value of the global market for DAC systems will climb past $2.3 billion by 2030.

Shell partners with UK-based co. for hydrogen electrolyzer pilot

ultra-efficient electrolyzer

Shell Global Solutions International, a subsidiary of Shell, which maintains its U.S. headquarters in Houston, has signed a collaboration agreement with London-based Supercritical Solutions to advance Supercritical’s ultra-efficient hydrogen electrolyzer technology toward a field pilot demonstration.

In the deal, the companies will collaborate on a paid technology feasibility study that will support the evaluation and planning of the pilot demonstration, according to a news release. Supercritical Solutions’ technology aims to deliver high-efficiency renewable hydrogen at a lower cost for the industrial hydrogen market.

"Signing this collaboration agreement with Shell is a major milestone for Supercritical Solutions and an important step on our commercialisation journey,” Luke Tan, co-founder of Supercritical, said in the news release. “We are directly addressing the cost and complexity barriers facing the renewable hydrogen market. We are excited to move forward with a company like Shell, whose global leadership has been proven to accelerate innovative technologies to market.”

Supercritical’s hydrogen electrolyser technology can operate at high temperatures and pressures of up to 220 bar without the need for an external hydrogen compressor, rare-earth materials or easily degradable membranes. The technology removes the typical compression step in the process while delivering hydrogen at industry standards. It requires significantly less energy than many traditional electrolyzers and is more cost-efficient.

This recent investment builds on an ongoing relationship between Shell and Supercritical. Supercritical was founded in 2020 and was runner-up in Shell’s New Energy Challenge, which helps startups and scaleups develop sustainable technologies, in 2021. Shell Ventures then invested in Supercritical’s Series A funding round in 2024 with Toyota Ventures.

3 Houston-area companies named to Global Cleantech 100

Energized

Three Houston-area companies—Amperon, Hertha Metals and Vaulted Deep—appear on this year’s Global Cleantech 100 list.

The unranked list, generated by market intelligence and advisory firm Cleantech Group, identifies the 100 privately held companies around the world that are most likely to make a significant impact in the cleantech market over the next five to 10 years.

For the 2026 list, Cleantech Group received more than 24,000 Global Cleantech 100 nominations from nearly 60 countries. Cleantech Group scored those companies and narrowed the contenders to 264. An expert panel reviewed those nominees, and the list was whittled down to the 100 winners.

Here’s a rundown of the three Houston-area honorees:

Amperon

Founded in 2018 by Sean Kelly and Abe Stanway, Houston-based Amperon offers an AI-enabled energy forecasting and analytics platform designed to help stabilize electric grids. Amperon received undisclosed amounts of venture capital from National Grid Partners and Tokyo Gas Co. Ltd. last year and announced a recent investment from Samsung Ventures earlier this month.

Hertha Metals

Founded in 2022 by Laureen Meroueh, Conroe-based Hertha Metals provides a single-step process for producing sustainable steel. Last year, the company emerged from stealth mode and raised more than $17 million in venture capital.

Vaulted Deep

Vaulted Deep’s technology injects excess organic waste underground to remove carbon dioxide from the atmosphere. Julia Reichelstein and Omar Abou-Sayed founded the Houston-based company in 2023. Last year, the startup raised $32.3 million in venture capital. Also in 2025, Vaulted Deep signed a 12-year deal with software giant Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.

Vaulted Deep also made the list last year, along with Houston-based Syzygy Plasmonics and Fervo Energy. Fervo was also named the 2025 North American Company of the Year by Cleantech Group.
