Amtrak and its partners will receive more than $2.1 billion in a federal program to improve existing routes and expand Amtrak service across the U.S.

That includes $500,000 from the Federal Railroad Administration awarded to the long-in-the-works high-speed rail project between Houston and Dallas, as well as another $500,000 awarded to the I-20 Corridor Long-Distance Passenger Rail Project.

The funding is via the newly-passed Infrastructure Investment & Jobs Act and includes multiple grants that will go to Amtrak and partners. This includes:

  • $108.5 million to Amtrak for station and service upgrades;
  • $2 billion to Amtrak partners in North Carolina, Virginia, Pennsylvania, and Maine for infrastructure upgrades
  • $34.5 million to 39 states and localities for planning and development of 69 new and improved intercity passenger rail corridors

These grants were awarded through the Federal Railroad Administration’s Federal-State Partnership for Intercity Passenger Rail Program for projects located across the National Network, as well as the Corridor Identification and Development Program (Corridor ID).

FRA Administrator Amit Bose says in a statement that these will be "transformative rail projects" that will provide climate-friendly alternatives to congested roads and airports.

“Today’s investments in passenger rail nationwide, made possible by the President’s Bipartisan Infrastructure Law, are another step forward as we expand and modernize our country’s rail network, providing more Americans the world-class passenger rail they need and deserve," Bose says.

Amtrak was awarded funding on a variety of projects, including four Corridor programs, designed to create a pipeline of intercity passenger rail projects.

Those include:

  • Texas High-Speed Rail Corridor. This proposed corridor would connect Houston and Dallas, Texas, with a new, dedicated and grade separated high-speed passenger rail service. This would provide new service on a new alignment, with station stops in Dallas, Brazos Valley and Houston.
  • Long Island Northeast Regional Extension. This proposed corridor would extend three existing daily Northeast Regional round trips between Washington, DC and New York City east to Ronkonkoma, NY, with stops at Jamaica (Queens, NY) and Hicksville, NY. This would entail track, station and infrastructure upgrades to accommodate these trains and better integrate Amtrak service with Long Island Rail Road commuter service.
  • Daily Cardinal Service. This proposed corridor would increase Cardinal service to operate daily, versus three days per week currently. This route operates between New York City and Chicago via Philadelphia, Baltimore, Washington, DC, Virginia, West Virginia, Kentucky, Ohio and Indiana.
  • Daily Sunset Limited Service. This proposed corridor would increase Sunset Limited service to operate daily, versus three days per week currently. This route operates between Los Angeles and New Orleans via Houston, San Antonio and El Paso, Texas; Tucson, Ariz.; and other communities.

The release does not say exactly how the $500,000 will be used. According to TxDOT, the current estimate for construction of track between Houston and Dallas is approximately $16 billion.

Houston-based ENGIE to add new wind and solar projects to Texas grid

coming soon

Houston-based ENGIE North America Inc. has expanded its partnership with Los Angeles-based Ares Infrastructure Opportunities to add 730 megawatts of renewable energy projects to the ERCOT grid.

The new projects will include one wind and two solar projects in Texas.

“The continued growth of our relationship with Ares reflects the strength of ENGIE’s portfolio of assets and our track record of delivering, operating and financing growth in the U.S. despite challenging circumstances,” Dave Carroll, CEO and Chief Renewables Officer of ENGIE North America, said in a news release. “The addition of another 730 MW of generation to our existing relationship reflects the commitment both ENGIE and Ares have to meeting growing demand for power in the U.S. and our willingness to invest in meeting those needs.”

ENGIE has more than 11 gigawatts of renewable energy projects in operation or under construction in the U.S. and Canada, and 52.7 gigawatts worldwide. The company is targeting 95 gigawatts by 2030.

ENGIE launched three new community solar farms in Illinois since December, including the 2.5-megawatt Harmony community solar farm in Lena and the Knox 2A and Knox 2B projects in Galesburg.

The company's 600-megawatt Swenson Ranch Solar project near Abilene, Texas, is expected to go online in 2027 and will provide power for Meta, the parent company of social media platform Facebook. Late last year, ENGIE also signed a nine-year renewable energy supply agreement with AstraZeneca to support the pharmaceutical company’s manufacturing operations from its 114-megawatt Tyson Nick Solar Project in Lamar County, Texas.

Houston geothermal company raises $97M Series B

fresh funding

Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.

Houston expert discusses the clean energy founder's paradox

Guest Column

Everyone tells you to move fast and break things. In clean energy, moving fast without structural integrity means breaking the only planet we’ve got. This is the founder's paradox: you are building a company in an industry where the stakes are existential, the timelines are glacial, and the capital requires patience.

The myth of the lone genius in a garage doesn’t really apply here. Clean energy startups aren’t just fighting competitors. They are fighting physics, policy, and decades of existing infrastructure. This isn’t an app. You’re building something physical that has to work in the real world. It has to be cheaper, more reliable, and clearly better than fossil fuels. Being “green” alone isn’t enough. Scale is what matters.

Your biggest risks aren’t competitors. They’re interconnection delays, permitting timelines, supply chain fragility, and whether your first customer is willing to underwrite something that hasn’t been done before.

That reality creates a brutal filter. Successful founders in this space need deep technical knowledge and the ability to execute. You need to understand engineering, navigate regulation, and think in terms of markets and risk. You’re not just selling a product. You’re selling a future where your solution becomes the obvious choice. That means connecting short-term financial returns with long-term system change.

The capital is there, but it’s smarter and more demanding. Investors today have PhDs in electrochemistry and grid dynamics. They’ve been burned by promises of miracle materials that never left the lab. They don't fund visions; they fund pathways to impact that can scale and make financial sense. Your roadmap must show not just a brilliant invention, but a clear, believable plan to drive costs down over time.

Capital in this sector isn’t impressed by ambition alone. It wants evidence that risk is being retired in the right order — even if that means slower growth early.

Here’s the upside. The difficulty of clean energy is also its strength. If you succeed, your advantage isn’t just in software or branding. It’s in hardware, supply chains, approvals, and years of hard work that others can’t easily copy. Your real competitors aren’t other startups. They’re inertia and the existing system. Winning here isn’t zero-sum. When one solution scales, it helps the entire market grow.

So, to the founder in the lab, or running field tests at a remote site: your pace will feel slow. The validation cycles are long. But you are building in the physical world. When you succeed, you don’t have an exit. You have a foundation. You don't just have customers; you have converts. And the product you ship doesn't just generate revenue; it creates a legacy.

If your timelines feel uncomfortable compared to software, that’s because you’re operating inside a system designed to resist change. And let’s not forget you are building actual physical products that interact with a complex world. Times are tough. Don’t give up. We need you.
