solar-powered spotlight

Green Mountain Energy Sun Club has supplied a grant of nearly $103,000 to a local Indian arts center to make sustainable improvements to its facilities.

Silambam Houston will use the grant to help with the installation of a rooftop solar array and a new pavilion at its Pearland dance studio, which will be called The Green Mountain Energy Sun Club Sustainability Pavilion. The venue will serve as an outdoor gathering space for events at the facility.

“At Green Mountain Energy, we recognize that our choices can have a profound impact on our environment,” Mark Parsons, Green Mountain Energy vice president, says in a news release. “We’re proud to support the rich and diverse culture of the Indian community, and we’re glad to help Silambam take the next step toward a more sustainable future.”

The 14.58 kW solar structure is expected to offset 100 percent of the building’s energy needs, which would save the organization more than $4,000 per year for the next 25 years. Sun Club has donated more than $14 million for 164 projects across Texas and the Northeast since it was founded in 2022.

Silambam is an Indian classical arts organization with an arts academy program that serves 180 students each week with more than 20 teaching artists on staff. The professional dance company has more than 20 dancers that regularly perform at Houston venues like Miller Outdoor Theater where they will perform next on June 7.

“We are thrilled to be able to weave sustainable practices into our arts programming, while also giving back to the community,” founder and executive artistic director of Silambam Dr. Lavanya Rajagopalan said in a news release. “The annual savings from this project will allow us to increase artist pay, provide tuition waivers for economically disadvantaged students, and/or provide free or pay-what-you-can access to our ArtStream Concerts, all while benefiting the environment.”

earth day win

Discovery Green celebrated Earth Day with a major milestone this year — achieving it’s Zero Waste goal.

The nonprofit, along with Citizens’ Environmental Coalition and Houston Public Works, are announced that the 2024 Green Mountain Energy Earth Day, which generated more than 3,800 pounds of garbage, diverted the majority of that waste from landfills. "Zero Waste," as defined by the Environmental Protection Agency, is successfully diverting at least 90 percent of waste from the landfill.

On Earth Day, Discovery Green composted 2,200 pounds of waste and recycled 1,300 pounds of trash.

“Part of Discovery Green Conservancy’s mission is to serve as a village green for our city and be a source of health and happiness for all. Our goal is to sustain an exceptional environment for nature and people,” Discover Green President Kathryn Lott says in a news release. “We are beyond thrilled to have achieved Zero Waste certification.”

The achievement was made possible by volunteers from the University of Houston – Downtown.

Steve Stelzer, president of Citizens’ Environmental Coalition’s board of directors, acknowledged how rare the achievement is in a public space in a major city like Houston.

“Discovery Green Conservancy stepped up and made a commitment to weigh, measure and record everything. They should be congratulated to have done this at this scale,” Stelzer adds. “The Conservancy said they were going to do it and they did. It’s an amazing accomplishment.”

The 2024 event included:

  • 31,000 visitors in attendance
  • 60 + exhibitors
  • 100 + volunteers
  • 12 artists
    • 9 chalk artists
    • Donkeeboy and Donkeemom
    • Mark Bradford
  • 25 Mark Bradford artworks made of scrap presented in partnership with Houston First
  • 4 short films shown
  • 3,836.7 pounds of waste collected during Green Mountain Energy Earth Day

Houston nonprofit flips switch on solar panel project thanks to sustainability grant

shine on

A Houston-area farm is one step closer to operating completely off-grid thanks to new solar panels installed with funding provided by a grant.

In a step towards a greener future, Hope Farms, a 7-acre farm operated by a Houston nonprofit organization, Recipe for Success Foundation, unveiled 18 new solar panels on Tuesday. This significant move is part of a collective effort to completely transition the farm to solar power, demonstrating its commitment to sustainability.

“The industry (solar power) itself is intimidating to people,” Gracie Cavner, founder and CEO of Hope Farms and Recipe for Success, tells EnergyCapital. “Part of our work is to inspire people to replicate what we're doing. We want to show that things aren't as hard as you think they are.”

The nonprofit organization is recognized in Houston for its work in addressing childhood obesity, with a long held mission of demystifying the common misconceptions around healthy eating. It is now tackling another challenge: dispelling the myth that solar power implementation is difficult. Hope Farms' latest initiative will not only further its energy independence, it will also show that adopting renewable energy, similar to embracing healthy food choices, is a feasible option.

The 18 solar panels will power the farm's composting toilet facility and all of the electricity used in its barn, which acts as its market stand and kitchen. Its next green phase is fast approaching and will implement solar panels on top of its flower studio, where the farm's internet and security systems reside. Its final phase will install a water well pump.

“We really did a lot of direct learning,” Cavner said. “We worked directly with solar engineers, not somebody with a company that benefited from us making one decision or another. I feel like more people would have solar if they realized they could do that.”

This is not the first green step Hope Farms has taken thanks to a Green Mountain Energy Sun Club grant, and certainly not the last. Last year, the farm cut the ribbons to its rainwater capture system that now saves roughly 95,000 gallons of water per year by capitalizing on the city’s abundant rainfall.

Since the farms beginning in 2016, it has relied on solar, even when it was only fields lit by a few lights. Soon, Hope Farms will be completely off-grid, running its entire operation on sustainable resources.

“With this expansion, I feel like it’s going to be taking the rock out of the middle of the river,” Cavner said. “It’s going to open up this train and make it easier for anybody to jump in and do it. The first step is kicking the door open and making more people want to pursue it.”

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.
