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.

Solar surpasses coal to become ERCOT’s third-largest power source in 2025

by the numbers

Solar barely eclipsed coal to become the third biggest source of energy generated for the Electric Reliability Council of Texas (ERCOT) in 2025, according to new data.

In 2024, solar represented 10 percent of energy supplied to the ERCOT electric grid. Last year, that number climbed to 14 percent. During the same period, coal’s share remained at 13 percent.

From the largest to smallest share, here’s the breakdown of other ERCOT energy sources in 2025 compared with 2024:

  • Combined-cycle gas: 33 percent, down from 35 percent in 2024
  • Wind: 23 percent, down from 24 percent in 2024
  • Natural gas: 8 percent, down from 9 percent in 2024
  • Nuclear: 8 percent, unchanged from 2024
  • Other sources: 1 percent, unchanged from 2024

Combined, solar and wind accounted for 37 percent of ERCOT energy sources.

Looking ahead, solar promises to reign as the star of the ERCOT show:

  • An ERCOT report released in December 2024 said solar is on track to continue outpacing other energy sources in terms of growth of installed generating capacity, followed by battery energy storage.
  • In December, ERCOT reported that more than 11,100 megawatts of new generating capacity had been added to its grid since the previous winter. One megawatt of electricity serves about 250 homes in peak-demand periods. Battery energy storage made up 47 percent of the new capacity, with solar in second place at 40 percent.

The mix of ERCOT’s energy is critical to Texas’ growing need for electricity, as ERCOT manages about 90 percent of the electric load for the state, including the Houston metro area. Data centers, AI and population growth are driving heightened demand for electricity.

In the first nine months of 2025, Texas added a nation-leading 7.4 gigawatts of solar capacity, according to a report from data and analytics firm Wood Mackenzie and the Solar Energy Industries Association.

“Remarkable growth in Texas, Indiana, Utah and other states ... shows just how decisively the market is moving toward solar,” says Abigail Ross Hopper, president and CEO of the solar association.

New UH white paper pushes for national plastics recycling policy

plastics paper

The latest white paper from the University of Houston’s Energy Transition Institute analyzes how the U.S. currently handles plastics recycling and advocates for a national, policy-driven approach.

Ramanan Krishnamoorti, vice president for energy and innovation at UH; Debalina Sengupta, assistant vice president and chief operating officer at the Energy Transition Institute; and UH researcher Aparajita Datta authored the paper titled “Extended Producer Responsibility (EPR) for Plastics Packaging: Gaps, Challenges and Opportunities for Policies in the United States.” In the paper, the scientists argue that the current mix of state laws and limited recycling infrastructure are holding back progress at the national level.

EPR policies assign responsibility for the end-of-life management of plastic packaging to producers or companies, instead of taxpayers, to incentivize better product design and reduce waste.

“My hope is this research will inform government agencies on what policies could be implemented that would improve how we approach repurposing plastics in the U.S.,” Krishnamoorti said in a news release. “Not only will this information identify policies that help reduce waste, but they could also prove to be a boon to the circular economy as they can identify economically beneficial pathways to recycle materials.”

The paper notes outdated recycling infrastructure and older technology as roadblocks.

Currently, only seven states have passed EPR laws for plastic packaging. Ten others are looking to pass similar measures, but each looks different, according to UH. Additionally, each state also has its own reporting system, which leads to incompatible datasets. Developing national EPR policies or consistent nationwide standards could lead to cleaner and more efficient processes, the report says.

The researchers also believe that investing in sorting, processing facilities, workforce training and artificial intelligence could alleviate issues for businesses—and particularly small businesses, which often lack the resources to manage complex reporting systems. Digital infrastructure techniques and moving away from manual data collection could also help.

Public education on recycling would also be “imperative” to the success of new policies, the report adds.

“Experts repeatedly underscored that public education and awareness about EPR, including among policymakers, are dismal,” the report reads. “Infrastructural limitations, barriers to access and the prevailing belief that curbside recycling is ineffective in the U.S. contribute to public dissatisfaction, misinformation and, in some cases, opposition toward the use of taxpayers’ and ratepayers’ contributions for EPR.”

Investment bank opens energy-focused office in Houston

new to hou

Investment bank Cohen & Co. Capital Markets has opened a Houston office to serve as the hub of its energy advisory business and has tapped investment banking veteran Rahul Jasuja as the office’s leader.

Jasuja joined Cohen & Co. Capital Markets, a subsidiary of financial services company Cohen & Co., as managing director, and head of energy and energy transition investment banking. Cohen’s capital markets arm closed $44 billion worth of deals last year.

Jasuja previously worked at energy-focused Houston investment bank Mast Capital Advisors, where he was managing director of investment banking. Before Mast Capital, Jasuja was director of energy investment banking in the Houston office of Wells Fargo Securities.

“Meeting rising [energy] demand will require disciplined capital allocation across traditional energy, sustainable fuels, and firm, dispatchable solutions such as nuclear and geothermal,” Jasuja said in a news release. “Houston remains the center of gravity where capital, operating expertise, and execution come together to make that transition investable.”

The Houston office will focus on four energy verticals:

  • Energy systems such as nuclear and geothermal
  • Energy supply chains
  • Energy-transition fuel and technology
  • Traditional energy
“We are making a committed investment in Houston because we believe the infrastructure powering AI, defense, and energy transition — from nuclear to rare-earth technology — represents the next secular cycle of value creation,” Jerry Serowik, head of Cohen & Co. Capital Markets, added in the release.
