Houston-based Sunnova Energy International, a provider of commercial and residential solar energy services, has teamed up with fintech platform Tenet Energy to help Americans buy electric vehicles and solar power systems.

The two companies will offer special discounts and financing plans to encourage Sunnova customers to switch to electric vehicles purchased through Tenet and Tenet customers to adopt Sunnova’s solar energy systems.

“Our suite of energy solutions — which includes EV chargers — addresses the concerns of higher electricity costs associated with fueling EVs while enabling buyers the convenience of charging from home as they electrify their transportation,” Michael Grasso, executive vice president and chief revenue officer at Sunnova, says in a news release.

The goal of the partnership is to enable homeowners to charge electric vehicles with solar power, which the companies say would lower utility and fuel costs.

“Our mission is to help Americans electrify their lives, starting with their vehicle,” says Alex Liegl, CEO of New York City-based Tenet. “EVs are an excellent way to begin your sustainability journey and save money, but they are also part of a broader energy system that works synergistically with other clean energy home assets like solar.”

Editor's note: Start your week off strong with three quick things to catch up on in Houston's energy transition: a roundup of events not to miss, a Houston energy executive to know, and more.

Needs improvement: Texas finishes low on list of EV charging stations despite increased efforts in Houston

A SmartAsset study looked at the closest EV charging stations equivalent to a trip to the gas station — factoring in each state's population. California, with its 14,500 charging stations, has five times the EV charging stations as New York (3,327), Florida (2,913) and Texas (2,472). While California ranked No. 1 on the list, Texas found itself at No. 41.

The report used EV charger and station data for each state from the U.S. Department of Energy for 2022 and 2021. Population data is for 2022 and comes from the U.S. Census Bureau 1-Year American Community Survey. Cities were also ranked by the number of fast chargers per capita. In 2022, Texas had 1,386 fast DC chargers, 2,472 EV charging stations, and a fast charger growth year over year 53.5 percent. Read more.

Incoming:  Houston recycling company names new CEO

David Hudson has been named CEO of Elemental Recycling. The company, founded in 2019, is an investment of Freestone, a portfolio company of Tailwater Capital. He succeeds Tom Samuels, former CEO and board chair of the company.

Texas City ammonia plant acquired by Yara in $1.3 billion deal

Ammonia Acquisition

Yara North America, a subsidiary of Norwegian fertilizer and ammonia producer Yara International, has agreed to buy an ammonia production plant in Texas City for $1.3 billion.

The seller is GCA Holdings, an affiliate of Texas City-based chemical manufacturer Gulf Coast Ammonia, which is owned by private equity firms Lotus Infrastructure Partners and MB Energy.

The Texas City plant, with an eventual annual capacity of 1.3 million metric tons, is expected to start full production by the end of this year. Yara says the ammonia produced by the plant will serve its own fertilizer production system and its key customers.

During a recent call with analysts and investors, Magnus Ankarstrand, executive vice president and CFO of Yara International, said the plant holds the potential to become one of the company’s most profitable plants. The $1.3 billion purchase price, he added, “is a very attractive entry ticket to ammonia production in the U.S. at a very attractive cost.”

The Texas City plant will add to Yara’s holdings in the Lone Star State, as Yara is the majority owner of an ammonia, hydrogen and nitrogen production plant in Freeport.

Construction of the ammonia plant began in 2020, but technical and infrastructure issues delayed the project. On its website, Gulf Coast Ammonia says the plant represented a $600 million investment.

“Gulf Coast Ammonia is a world-class asset that required disciplined execution across development, financing, construction, and commercial structuring,” Philipp Pletka, managing director of Lotus Infrastructure Partners, says in a news release.

Trexlertown, Pennsylvania-based Air Products, which owns and operates the country’s largest hydrogen pipeline network, will continue to supply hydrogen and nitrogen for the plant under a long-term deal with Yara, according to the release.

However, the news comes two days after Yara International announced that it would no longer be purchasing ammonia assets in the Louisiana Clean Energy Complex (LCEC) from Air Products. In a separate release, Yara said it planned to reallocate funds toward "alternative mature U.S. ammonia investment opportunities with more competitive returns."

Houston hypersonic engine company lands $91M to accelerate production

Clean Speed

Houston-based Venus Aerospace has closed a $91 million Series B round and plans to scale the production of its hypersonic engine.

The round was led by Houston-based Mercury Fund with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity and other investors, according to a news release.

The investment comes about a year after Venus completed the first U.S. flight test of its high-thrust rotating detonation rocket engine (RDRE). The engine is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus Aerospace says the latest round of funding will allow it to move the RDRE from demonstration to deployment and meet customer requirements for the near-term defense and space industries. The company says that the reusable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types.

“This financing marks an important step in moving Venus from breakthrough demonstration to scaled capability,” Sassie Duggleby, co-founder and CEO, said in the news release. “Our customers need propulsion systems that go farther, can be produced reliably and are built on supply chains they can trust. We are advancing that capability with American engineering and manufacturing talent to strengthen U.S. defense, expand space access and support the future of high-speed flight.”

Venus Aerospace raised a $20 million Series A in 2022, led by Wyoming-based Prime Movers Lab. At the time, the company said it would put the funding toward three main technologies: a next-generation rocket engine, aircraft shape and leading-edge cooling system.

The company also picked up an investment from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, in November 2025—in addition to funding from other investors over the years.

“Since our initial investment, Venus has progressed very quickly in its technology development," Chris Moran, vice president and general manager of Lockheed Martin Ventures, added in the release. "Our reinvestment in Venus recognizes Venus’ accomplishments to date and focus on speed to manufacture, cost management and reduction of supply chain constraints. Venus is working effectively to position its propulsion system for the production scale required by defense programs.”

"Venus is exactly the kind of company Houston capital should be backing," Blair Garrou, co-founder and managing partner at Mercury Fund, added in the release. "It combines multiple frontier technologies, domestic manufacturing and clear commercial and national security relevance. We believe this team is positioned to lead an important new chapter in defense and space, and we are proud to support a company building breakthrough technology here in Texas."

Venus Aerospace and Houston clean tech startup Vaulted Deep were also named to the World Economic Forum's Technology Pioneers community earlier this summer.
