The Rio Grande LNG Project (RGLNG), an LNG export facility in Cameron County, Texas with planned capacity for exporting up to 27 million tons of LNG per year, makes a giant leap toward the final investment decision stage with the latest agreements signed by NextDecade Energy announced earlier today.

Entry to this next phase includes executing investor agreements with Global Infrastructure Partners (GIP) and TotalEnergies (TTE). In addition, TTE commits to purchasing 5.4 million tons of LNG annually for the next 20 years from the first three trains (RGLNG Phase 1) that will transport to the facility, with additional options to purchase from subsequent trains.

“This announcement marks a momentous milestone for NextDecade,” said Matt Schatzman, chairman and CEO of NextDecade, in the release. “We are excited to work with GIP and TotalEnergies on RGLNG and our proposed CCS project at RGLNG. We are also eager to grow our partnership with GIP and TotalEnergies focusing on our shared vision to reduce carbon emissions in the energy sector.”

“With the world increasingly moving toward sustainable solutions, this partnership among GIP, TotalEnergies and NextDecade reinforces our shared commitment to helping lead the transition and shaping of the future of energy,” added Bayo Ogunlesi, chairman and Chief Executive Officer of Global Infrastructure Partners. “This venture marks a critical step in displacing coal usage and upholds GIP’s commitment to promoting decarbonization, energy security and energy affordability. Our shared vision with TotalEnergies and NextDecade, combined with our capabilities, will undoubtedly help catalyze the development of cleaner energy.”

"We are delighted to join forces with NextDecade and GIP on the development of this new US LNG project, for which TotalEnergies shall leverage its extensive experience in LNG and technical expertise in major industrial project development," commented Patrick Pouyanné, chairman and CEO of TotalEnergies. “Our involvement in this project will enhance our LNG capacity by 5.4 MTPA strengthening our ability to ensure Europe's gas supply security and to provide Asian customers with an alternative fuel that emits half as much as coal.”

Pending execution of the FID and definitive documentation, GIP becomes the majority investor in Phase 1 of the RGLNG, and TTE will acquire another 16.67%. Both companies will also have options to invest in Trains 4 and 5 servicing the South Texas LNG export facility and options to invest in future carbon capture and sequestration (CCS) efforts planned for RGNLG.

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.

Houston AI energy forecasting company lands investment from Samsung Ventures

funding for forecasts

Amperon, a Houston-based AI-powered forecasting solutions company, has received an investment for an undisclosed amount from Samsung Ventures, the corporate venture arm of Samsung Group.

According to Amperon, the funding will be put toward the company's global growth and next-generation product development. Samsung Ventures invests in emerging businesses developing technologies for the AI, advanced devices and energy-related sectors.

“Samsung Ventures’ investment is a strong validation of our mission to transform the way energy is forecasted and traded,” Sean Kelly, CEO and co-founder of Amperon, said in a news release. “Samsung’s global footprint and leadership in semiconductors, data infrastructure, and AI acceleration make them a natural fit as we expand Amperon’s reach into energy-intensive sectors like data centers. Their track record of scaling next-generation technologies aligns perfectly with our vision to build a more intelligent, resilient, and data-driven energy system.”

Amperon was founded in 2018. Its AI models combine real-time weather, consumption and market data for energy retailers, utilities and independent power producers.

Last year, the company launched its weather-informed grid demand Mid-Term Forecast (MTF), which provides users with data on electricity demand up to seven months in advance. It also secured strategic investments from Acario, the corporate venture capital and innovation division of Tokyo Gas, as well as National Grid Partners, the venture investment and innovation arm of National Grid (NYSE: NGG).

After expanding into Europe in 2024, the company has continued to see international growth, and currently operates in the U.S., Canada, Mexico, Australia, Europe and the Middle East.

“Amperon has demonstrated strong technical capabilities and global traction in a rapidly evolving energy landscape,” a spokesperson for Samsung Ventures added in the release. “Their ability to forecast and model real-time energy data at global scale positions them as a key enabler of smarter energy systems and climate resilience. We are pleased to invest in a company developing technologies that support a more sustainable and digitized world.”
