Houston energy dealmaker Stephen Trauber has been tapped as chairman and global head of the energy and clean technology business at publicly traded investment bank Moelis & Co.

In 2010, The Wall Street Journal called Trauber “one of the best-connected energy bankers in Houston.”

Trauber comes to New York City-based Moelis from Citi, where he recently retired as vice chairman and global co-head of natural resources and clean energy transition. Before that, he was vice chairman and global head of energy at UBS Investment Bank, where he worked with Ken Moelis, who’s now chairman and CEO of Moelis.

“The global energy ecosystem is undergoing major consolidation and change,” Trauber says in a Moelis news release. “I look forward to actively participating in its strategic evolution and working with so many of our clients that are evaluating how best to create value during this period of transformation.”

In conjunction with Trauber’s hiring, Guggenheim Securities executives Muhammad Laghari and Alexander Burpee are joining Moelis as managing directors in Houston. They’ll work with upstream and midstream oil and gas clients. Laghari and Burpee previously were colleagues of Trauber at Citi.

During his career, Trauber has advised on more than $700 billion in energy deals, including mergers, acquisitions, and IPOs. Among the industry heavyweights involved in those deals were BP, Halliburton, Kinder Morgan, Nabors, Occidental Petroleum, Schlumberger, Shell, and Weatherford International.

“Steve is a recognized leader in the industry who has played a key role in many of the energy sector’s landmark transactions,” says Navid Mahmoodzadegan, co-founder and co-president of Moelis.

Three years ago, Trauber made waves when Spring-based ExxonMobil

rejected his pitch “to commit to a target for net-zero emissions even after shareholders staged a revolt over the company’s climate policy,” Bloomberg reported at the time.

Last year, Trauber joined the board of directors of Houston-based NEXT Renewable Fuels, the board of directors of Houston-based ASEAN Energy, and the M&A and transactions advisory board of London-based professional services giant Aon.

The three new hires at Moelis follow the September 2023 launch of its Clean Technology Group. Arash Nazhad of Houston is co-leader of the group.

Investment banking firm launches cleantech group, names Houston-based co-leader

new hire

A Houston investment banker has been tapped as co-leader of a new team at investment bank Moelis & Co. that will mine the energy sector for cleantech deals.

Publicly traded Moelis said September 7 that it hired Arash Nazhad as Houston-based managing director and co-head of its newly formed clean energy technology group. Nazhad joins Moelis from financial services giant Citigroup, where he was managing director of its clean energy investment team. He worked at Citigroup for nine years.

During his tenure at Citigroup and, before that, Norwegian energy company Equinor (which operates a Houston office), Nazhad helped carry out more than $50 billion in M&A advisory activities and helped raise over $40 billion in capital for clients. He’s been involved in the rollout of more than 20 IPOs.

“Moelis is very well-positioned to help clients navigate the far-reaching implications of the energy transition that is underway,” Nazhad tells EnergyCapitalHTX. “Houston is a major player in the cleantech ecosystem, and I’m thrilled to join Moelis and leverage the breadth of the firm’s capital market solutions, advisory services, and global connectivity to support clients in this space.”

Nazhad will run the new Moelis group alongside Rick Polhemus, the investment bank’s San Francisco-based managing director. Polhemus, formerly an executive at investment bank Morgan Stanley, joined Moelis last October.

Jeff Raich, co-founder and co-president of Moelis, says the backgrounds of Nazhad and Polhemus make them “uniquely positioned to lead our efforts and expand opportunities for clients in this rapidly changing environment.”

“The energy transition that is underway demands integrated advisory services, access to capital, and strategic long-term planning,” adds Navid Mahmoodzadegan, co-founder and co-president of Moelis.

“Achieving net-zero emissions will require a significant increase in spending,” Mahmoodzadegan adds, “and our dedicated clean energy efforts better position us to be a seamless partner to our strategic, financial sponsor, and venture capital clients as we leverage our dynamic advisory practice and global connectivity.”

Nazhad and his colleagues will be searching for cleantech deals in a supercharged sector.

The International Energy Agency says global investment in cleantech is on track to hit $1.7 trillion this year. An impressive share of that money is being pumped into cleantech startups. Globally, VC funding in the cleantech sector soared from $1.9 billion in 2019 to $12.3 billion in 2022, according to management consulting firm Oliver Wyman.

Nazhad’s M&A experience should prove particularly beneficial for Moelis’ new cleantech arm.

A recent report from management consulting firm West Monroe indicates cleantech M&A “is picking up speed.” The report is based on the firm’s survey of 200 corporate and private equity executives.

“The overarching trend is that cleantech is no longer the stuff of speculation, but a viable sector benefiting from a confluence of tailwinds, including high energy demand, the need for secure supplies that complement fossil fuels, and more ambitious policymaking efforts targeting decarbonization,” the report says.

Hobby debuts solar canopy as airport system reaches new sustainability milestone

solar solutions

Houston's William P. Hobby Airport is generating its own clean energy.

Houston Aiports announced that Hobby's red garage is now home to a "solar canopy" that is producing energy at 100 percent capacity to power daily operations. The photovoltaic (PV) solar system generated more than 1.1 gigawatt-hours of electricity in testing, and is expected to produce up to 1 megawatt-hour now that it's operating at full power.

“This project is proof that sustainability can be practical, visible and directly tied to the passenger experience,” Jim Szczesniak, director of aviation for Houston Airports, said in a news release. “Passengers now park under a structure that shields their cars from the Texas sun while generating clean energy that keeps airport operations running efficiently, lowering overall peak demand electrical costs during the day and our carbon footprint. It’s a win for travelers, the city and the planet.”

The project was completed by Texas A&M Engineering Experiment Station (TEES) and CenterPoint Energy. It's part of Houston Airport's efforts to reduce carbon emissions by 40 percent over its 2019 baseline.

In a separate announcement, the airport system also shared that it recently reached Level 3 in the Airports Council International (ACI) Airport Carbon Accreditation program after reducing emissions by 19 percent in three years. This includes reductions at George Bush Intercontinental Airport (IAH), Hobby and Ellington Airport/Houston Spaceport.

The reductions have come from initiatives such as adding electric vehicles to airport fleets, upgrading airfield lighting with LED bulbs, adding smarter power systems to terminals, and improving IAH's central utility plant with more efficient equipment. Additionally, the expansion to Hobby's West Concourse and renovations at IAH Terminal B incorporate cleaner equipment and technology.

According to Houston Airports, from 2019 to 2023:

  • IAH reduced emissions by 17 percent
  • Hobby reduced emissions by 32 percent
  • Ellington Airport reduced emissions by 4 percent

"I see firsthand how vital it is to link infrastructure with sustainability,” Houston City Council Member Twila Carter, chair of the council’s Resilience Committee, said in the release. “Reducing carbon emissions at our airports isn’t just about cleaner travel — it’s about smarter planning, safer communities and building a Houston that can thrive for generations to come.”

Houston Methodist leader on the push for sustainable health care and new local event

Q&A

Every industry can play a role in the energy transition, and Houston Methodist is leading the charge in the health care sector.

Culminating at this week’s inaugural Green ICU Conference, part of Houston Energy and Climate Startup Week, the health care system has spent the last three years taking a closer look at its environmental footprint—and showing other hospital systems and medical organizations how they too can make simple changes to reduce emissions.

The event, held tomorrow, Sept. 17, at TMC Helix Park, will bring together health care professionals, industry leaders, policymakers and innovators to explore solutions for building a more sustainable healthcare system.

In an interview with EnergyCapital, Dr. Faisal N. Masud, medical director of critical care at Houston Methodist and a champion for sustainability efforts across the system, shares the inspiration behind the event and what attendees can expect to take away.

Tell us about how the Green ICU Conference came to be.

Houston Methodist’s inaugural Green ICU conference is about three years in the making. It originated because Houston Methodist recognized the significant impact health care has on sustainability and the lack of similar initiatives in the U.S.

The Center for Critical Care at Houston Methodist launched a sustainability-focused ICU initiative, published a roadmap and became involved in international efforts to develop guidelines that many other organizations now use. Our work led to the creation of the first Green ICU Collaborative in the country, and the Green ICU Conference was established to share best practices and address the global impact of critical care on the environment.

What were some of the biggest takeaways from the collaborative, and how are they represented in this new event?

Through the Green ICU Collaborative, we’ve seen that health care professionals can make a significant impact on sustainability through simple, practical changes, and many solutions can be implemented without major costs or compromising patient care. Additionally, there’s a strong link between environmental stewardship and patient safety and quality. These lessons will be represented in the new Green ICU Conference by showcasing easy-to-adopt best practices, emphasizing the importance of sustainability in daily health care operations, and fostering a sense of shared responsibility among attendees to improve both patient outcomes and environmental impact.

Why are ICUs considered to be such carbon hot spots?

ICUs are considered carbon hot spots because they care for the sickest patients, requiring intensive therapies, numerous medications and a large amount of equipment, such as ventilators and pumps. This makes them the most resource- and energy-intensive areas in a hospital. A single day in the ICU can have a greenhouse gas impact equivalent to driving a car 1,000 kilometers.

The U.S. health care sector is responsible for approximately 8.5 percent of greenhouse gas emissions, and hospitals are the second-most energy-intensive commercial buildings in the country. With the Texas Medical Center being in the heart of Houston, it’s critical that health care organizations play a role in this area.

That’s why the Center for Critical Care launched a system-wide Green ICU Initiative with the Houston Methodist Office of Sustainability to help reduce our carbon impact and waste while continuing to provide unparalleled patient care. Innovation is part of our culture, and that extends into our sustainability efforts. Houston Methodist’s Green ICU initiative is the first-of-its-kind in the U.S.

What efforts has Houston Methodist taken to cut emissions?

The first step to cutting emissions is measuring an organization’s carbon footprint to determine the best path forward. Houston Methodist’s Office of Sustainability has aggregated two years of baseline emissions data pending third-party validation. The hospital has taken several steps to cut emissions, including implementing composting programs, installing solar panels, improving energy utilization and participating in global plastic recycling initiatives. These efforts are part of a broader commitment led by our Office of Sustainability to reduce the hospital’s environmental footprint.

Tell us a little more about the event. Who should attend? What do you expect to be some of the highlights?

The Green ICU Conference, taking place during Houston Energy and Climate Week, is focused on health care sustainability, bringing together health care professionals, engineers, experts and anyone interested in reducing health care’s environmental impact. With participants and speakers from six countries, the conference brings together leading experts who aim to raise awareness, share best practices and offer practical, easy-to-adopt solutions for making health care more sustainable.

Highlights include perspectives from leading voices in health care sustainability, real-world examples of successful sustainability initiatives and opportunities for networking and collaboration. Anyone interested in health care, sustainability,or making a positive impact in their community should consider attending.

And, because of increasing interest, we’ve opened up the opportunity for attendees to join virtually at no cost or in person.

What do you hope attendees take away? What are your major goals for the event?

The main goals of hosting the Green ICU Conference for the first time are to raise awareness about the environmental impact of health care; engage and empower attendees to implement easy, practical sustainability solutions; and foster a sense of shared community and responsibility.

I hope attendees leave the event feeling motivated and equipped to make meaningful changes in their own practices, whether that’s improving patient care, supporting their colleagues, or leaving their organization and environment in a better place for future generations.

Texas House Democrats urge Trump administration to restore $250M solar grant

solar grants

Eight Democratic members of the U.S. House from Texas, including two from Houston, are calling on the Trump administration to restore a nearly $250 million solar energy grant for Texas that’s being slashed by the U.S. Environmental Protection Agency (EPA).

In a letter to Lee Zeldin, head of the EPA, and Russell Vought, director of the federal Office of Management and Budget (OMB), the House members urged the two officials to reinstate the nearly $250 million grant, which was awarded to Texas under the $7 billion Biden-era Solar for All program. The Texas grant was designed to assist 28,000 low-income households in installing solar panels, aiming to reduce their energy bills.

“This administration has improperly withheld billions in congressionally appropriated funding that was intended to benefit everyday Americans,” the letter stated.

The letter claimed that numerous court rulings have determined the EPA cannot repeal already allocated funding.

“Congress made a commitment to families, small businesses, and communities across this country to lower their utility bills and reduce harmful pollution through investments in clean energy. The Solar for All program was part of that commitment, and the EPA’s actions to rescind this funding effectively undermine that congressional intent,” the House members wrote.

The six House members who signed the letter are:

  • U.S. Rep. Sylvia Garcia of Houston
  • U.S. Rep. Al Green of Houston
  • U.S. Rep. Greg Casar of Austin
  • U.S. Rep. Jasmine Crockett of Dallas
  • U.S. Rep. Lloyd Doggett of Austin
  • U.S. Rep. Julie Johnson of Dallas
  • U.S. Rep. Marc Veasey of Fort Worth

The nearly $250 million grant was awarded last year to the Harris County-led Texas Solar for All Coalition.

In a post on the X social media platform, Zeldin said the recently passed “One Big Beautiful Bill” killed the Greenhouse Gas Reduction Fund, which would have financed the $7 billion Solar for All program.

“The bottom line is this: EPA no longer has the statutory authority to administer the program or the appropriated funds to keep this boondoggle alive,” Zeldin said.
