Founded in 2015, Activate Global Inc. is a 501(c)3 nonprofit organization that partners with US-based funders and research institutions to support scientists at the outset of their entrepreneurial journey by providing personalized expertise, tools, and resources that may otherwise be inaccessible. The organization recently launched its fifth community in Houston, and just closed the application window for the 2024 Activate Fellowship Cohort.

We recently connected with energy industry veteran and Activate Houston Managing Director Jeremy Pitts to learn more about how Activate is empowering scientists and engineers as they pave the way to a low-carbon future.

HETI: Activate was founded in 2015 and has established fellowship programs in Silicon Valley, Boston, New York, and a remote Anywhere Community. Why was Houston the next logical choice for an Activate Community?   

Jeremy Pitts: There is no doubt that Houston is going to be a major player in the energy transition, so it’s a logical place for Activate to be as we do our part to help bring ground-breaking technology out of the lab and deploy it to solve the world’s biggest challenges.

Houston is already the best place to scale a company working on the types of hard tech solutions that Activate focuses on. Houston has the talent, capital, and resources to build and deploy things at the scale needed to have a global impact. There is a good chance that many of our current Activate companies and alumni will end up in Houston as they pursue their scale-up plans. Activate alum Tim Latimer and Fervo Energy are great examples of this.

Houston is also an interesting fit for Activate as we believe we can fill a gap in the current ecosystem by providing support for entrepreneurs at the earliest stages of their journey. By providing funding and support, we can keep those entrepreneurs in Houston as opposed to moving to the coasts. We are hopeful that not only can we directly support a small number of the most promising entrepreneurs, but we can indirectly support many more by creating an ecosystem where early-stage capital starts to find its way to Houston to support these revolutionary and impactful technologies.

HETI: Activate Communities work closely with climate tech programs at leading colleges and universities, including UC Berkeley, U Mass Boston, and Columbia University. What can you tell us about Activate Houston’s plans for collaboration with area colleges and universities?

JP: Activate’s goal is to be as inclusive as possible. One of our main goals is to find fellows who we can have as big of an impact on as possible, potentially being the difference between whether they are successful or not. To that end, we plan to partner and engage with all of the research institutions across Houston and the surrounding areas. In just our first few months of being on the ground in Houston and recruiting for our first cohort, we have already engaged with Rice, UH, Prairie View A&M, TSU, Texas A&M, UT, and the Texas Medical Center. We have also begun outreach and preliminary conversations with institutions outside of the Houston area, like UT Dallas, SMU, Baylor, UTEP, etc. Our goal is to find the most promising entrepreneurs and the most impactful technologies that we can help and support, regardless of where they come from.

We will also be looking to engage with some of these institutions to make resources available to our fellows to support the research they are doing once in the Activate program. These conversations are in the early stages, but the facilities at UH Technology Bridge and TMC’s Innovation Factory are great examples of how the Houston ecosystem can support our fellows.

HETI: How do fellowships like Activate differ from traditional accelerator programs and why are they such an important component of the energy transition?

JP: Accelerators in general are a great resource for entrepreneurs to quickly learn the fundamentals around building a company and gain access to a network of investors, mentors, and partners that they would have trouble accessing on their own.

While Activate has a lot of overlap with accelerators in terms of what we provide, we classify ourselves as a fellowship and not an accelerator. The reasons for this primarily lie in the fact that we are a non-profit. This allows us to do a few things different from traditional accelerators. First, our program does not charge any fees or equity. Because our success is not tied to the financial outcomes of the companies, we are able to take much bigger risks in terms of the technology we support and we are also able to take a fellow first approach, as sometimes the best outcome for the fellow as a person is not the best financial outcome for the company. Second, we are much more patient, offering a full two years of support for our fellows and continuing to support our alumni community after they have left the program.

Activate’s unique fellowship program can play an essential role because many of the technologies and breakthroughs necessary to solve the world’s biggest challenges are really hard. It can take a long time to develop these technologies and often they are too risky and unproven at the early stages to be able to attract the capital they need to turn the technology into a commercial solution. Activate can support these hard technologies and provide a two-year safety net for our fellows as they work through those early challenges and progress their solution to a point that the private markets will support the business coming out of our program. We have been quite successful with this approach thus far, as the 145 companies we have created have raised nearly $1.4B in follow-on funding, representing a 23X multiplier on the funds Activate has directly deployed to support the fellows.

HETI: You’re the co-founder of Greentown Labs, now the nation’s biggest climate tech incubator. How does that experience help in your new role as MD at Activate Houston?

JP: The biggest takeaway for me from my time building Greentown is the power of community. Early-stage deep tech founders face monumental challenges. Having a community of like-minded individuals nearby who are facing their own similar challenges and serve as both a support network and a sounding board to help work through those challenges can be the difference between success and failure. I hope to leverage those learnings to really focus on Activate Houston being an incredibly strong community where the founders can lean on each other, and me, for the support they need.

In addition, Greentown also serves as a gathering place for bringing the larger climate community together, which is so vital in pushing forward the energy transition. In the early days of Greentown, those events happened on an almost ad hoc basis, as there wasn’t previously a place for people interested in climate to gather. Greentown has changed a lot over the years – the facilities are quite a bit nicer than where we started – but it has done an amazing job continuing to fill that role as the center of the climate ecosystem and bringing together a community of like-minded individuals. Anyone who attended the recent Greentown Climatetech Summit and experienced the standing-room-only crowds of passionate people can attest to that. Certainly, Greentown already fills that role for Houston and does it well, but my experience with the power of community will lead me to lean into Houston’s climate community and encourage our fellows to do the same, to be active members in strengthening the entire climate and innovation ecosystem in Houston. All boats rise together in the rising sea that is Houston’s climate and innovation ecosystem.

HETI: What are you most looking forward to with the upcoming launch of Houston’s 2024 Cohort?

JP: I’m looking forward to getting started – welcoming our first cohort into Houston and showing the rest of the country that Houston can hold its own when it comes to hard tech and world-changing innovation.

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.
