Diamond Infrastructure Solutions has given Third Pillar Solar exclusive rights to access Diamond’s Texas reservoirs for the possible launch of utility-scale floating solar installations. Both companies are based in the Houston area.

The potential investment in the floating solar project exceeds $700 million, and the project is expected to generate up to 500 megawatts of solar energy.

“Our agreement with Third Pillar marks a bold step forward in how we think about infrastructure and sustainability. By transforming underutilized water surfaces into clean energy assets, Diamond is advancing its commitment to innovation while delivering long-term value,” Ed Noack, CEO of Diamond Infrastructure Solutions, said in the release.

Dow Chemical Co. and a fund directed by Macquarie Asset Management announced the formation of Diamond in 2024. Dow holds a majority stake in Diamond, which owns Gulf Coast infrastructure used by Dow and other industrial customers at five locations in Texas and Louisiana.

The solar installations are scheduled to be built and in operation by the end of the decade.

The agreement between Diamond and Three Pillar “demonstrates the growing appetite for utility-scale energy solutions and highlights how floating solar can enhance and transform the value of existing infrastructure, all while providing cost-competitive energy, preserving agricultural land, reducing evaporation losses, and existing out of public view,” Jaimeet Gulati, CEO of Third Pillar, added in the realease.

Founded in 2022 and majority-owned by renewable energy investor Glentra Capital, Third Pillar develops, owns and operates floating photovoltaic solar installations. The installations are designed to float in places such as wastewater lagoons, reclaimed sand and gravel pits and industrial reservoirs. Third Pillar’s development pipeline contains more than 60 projects.

The Texas-Louisiana Gulf Coast is the backbone of America’s energy and chemical economy. Texas produces roughly 43% of U.S. crude oil and 28% of natural gas, while Texas and Louisiana together account for about half of the nation’s refining capacity, processing 9.3 million barrels of crude per day across 50 refineries. The region also produces approximately 80% of the nation’s primary petrochemicals and ships more than $117 billion in chemical products annually from Texas alone. Continue reading.

4. 8 CERAWeek 2026 takeaways from a new Houston energy leader

My first CERAWeek was a blur. Having top energy executives, policymakers, and technologists all gathered in Houston—over 11,000 of them this year—was both overwhelming and energizing. The theme was “Convergence and Competition: Energy, Technology, and Geopolitics,” and walking through the George R. Brown Convention Center, it was immediately clear that this was no ordinary industry conference. As a first-timer with a Greentown Labs lens, here’s what really stuck with me. Continue reading.

5. Greentown Labs names new COO, appoints new Head of Houston

Greentown Labs has reshuffled its leadership, elevating Houston leaders into new roles. Lawson Gow was named COO of the Houston- and Boston-based climatech incubator in February 2026. In his new role, he will focus on optimizing Greentown's structure, building new internal and external systems and developing a plan for growth. Continue reading.

Rice, UH launch joint effort to accelerate plastics recycling solutions

plastics partnership

Institutes at two Houston universities are joining forces to help position the city as a global leader in plastics recycling innovation.

The Center for Energy Studies (CES) at Rice University’s Baker Institute for Public Policy and the University of Houston’s Energy Transition Institute (UH-ETI) have announced a strategic partnership that aims to develop real-world solutions for plastic recycling.

The universities will kick off the new initiative with the Annual Sustainability Summit: Innovations and Collaborations in Circularity & Supply Chain Resilience event April 22 at the Baker Institute.

“Houston sits at the center of the global plastics and petrochemical value chain, which makes it uniquely positioned to lead in circular solutions,” Rachel Meidl, deputy director of CES, said in a news release. “This partnership is about moving beyond theory and bringing together data, policy and industry insight to accelerate technologies and frameworks that can scale.”

The partnership—which was made official during CERAWeek—will integrate policy, economics, science and engineering. The universities will work to “share data, insights, networks and connections to advance global work in protecting the environment, economy and society,” according to a news release from Rice.

Initially, the universities will focus on evaluating scalable advanced recycling pathways, developing policy frameworks to improve plastics circularity, analyzing emerging technology and using industry stakeholders for deployment.

Plastics circularity aligns with Rice and UH’s energy transition efforts to advance a circular economy. UH's ETI recently published a white paper that analyzes how the U.S. currently handles plastics recycling and advocates for a new approach. Ramanan Krishnamoorti, author of the paper and vice president of energy and innovation at UH, said the partnership with Rice’s Baker Institute could help bring some of the ideas outlined in the paper to reality.

“Our research has shown that a uniform approach may be the best way for the U.S. to tackle plastic waste,” Krishnamoort said in a news release. “By partnering with Rice’s Baker Institute for Public Policy, we will be better positioned to deliver real-world solutions that advance a circular plastics economy.”

Fervo Energy adds former eBay CEO Meg Whitman, other leaders to board

power players

As it prepares for a highly anticipated IPO, Houston-based geothermal power provider Fervo Energy has added four heavyweights to its board of directors.

The most notable new board member is Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE, and former U.S. ambassador to Kenya. She joined the Fervo board as lead independent director.

One of the other high-profile new board members at Fervo is Jessica Uhl. She was chief financial officer of Shell from 2017 to 2022 and spent a little over a year as president of GE Vernova, a GE energy spinoff. She is a former board member of GE, Goldman Sachs and Shell. Today, Uhl advises investment firms on energy matters.

Another energy industry veteran, Trey Lowe, also joined the Fervo board. Lowe is senior vice president and chief technology officer at oil and gas producer Devon Energy, a Fervo investor that’s moving its headquarters from Oklahoma City to Houston. Before Devon, Lowe worked in the U.S. and Norway for Houston-based energy technology company SLB.

The fourth new director at Fervo is Robert Keehan, who spent 37 years at professional services firm PwC. He most recently was PwC’s chief global auditor and earlier was a partner in the firm’s energy practice.

Keehan and Uhl will serve as independent directors, which are non-executive governance and oversight roles, while Lowe is a non-independent director, which is a more hands-on role.

With the four new directors, Fervo has seven board members.

The arrival of the four new board members comes at a monumental time for Fervo, a provider of utility-scale geothermal energy:

“Energy markets are demanding dependable, carbon-free power at an unprecedented scale, and Fervo is uniquely positioned to supply it,” Tim Latimer, co-founder and CEO of Fervo, said in December.
