Jeffrey Benoit, Vice President of Clean Energy Solutions at PSM - a Hanwha company, and Bobby Noble, Senior Program Manager, Gas Turbine R&D – EPRI, spoke to

at PowerGen 2025 in downtown Dallas. The duo discussed roadblocks with lower-carbon fuel supply, how technology is not standing in the way of advancing gas turbines in the new energy era, and, as Noble said, “Carbon capture is just another tool in our toolbox” of developing a cleaner energy landscape.

Jeffrey Benoit of PSM says there are no big technical barriers, “it’s a matter of getting these technologies into products and commercially operated gas turbines.”

Gas Turbines Don’t Suffer from Technical Roadblocks, Just To Market 

TURBO: Are there any policy- or technology-related roadblocks for gas turbines during the clean energy transition?

 When we think about roadblocks, there are technical aspects and certain limitations for as-found gas turbines. But then, of course, there's the entire supply chain for the hydrogen. Where is hydrogen or ammonia or other low-carbon/no-carbon fuel coming from? Those are challenges that are being addressed by other parts of the industry. As we focus on the gas turbine itself, it's really just the continual development of capabilities.

 One of the great things that we're focused on is we, from a technology standpoint, don't see any significant barriers. It is simply a just a matter of putting the pedal to the metal and getting these technologies into products, validated, not only in 10th full-pressure, full-condition test rigs but also into gas turbines that are operating in a commercial environment and finding that partner with an operator—that is part of the DNA of PSM. A lot of our capabilities and products have been done with these true innovators looking to put first-of-a-kind types of technology. So, when it comes to fuel flexibility and optionality, this is an area we are very focused on. It's just a matter of focusing on it and getting it done. We know the hydrogen economy; the ammonia economy is coming; we want to be right there and make it as seamless as possible for the end users, particularly those in power, to take advantage of this.

TURBO: How does carbon capture and sequestration (CCS) fit into this developing energy landscape?

 Carbon capture is another tool in our toolbox. So, when we think about options, this is yet another option. As Jeff and some of our other panelists pointed out this morning, as we're looking at 

the role of the gas turbine in the future

, we think about a base-loaded combined cycle unit that may not be the ideal place to utilize hydrogen or ammonia, simply because of the sheer amounts of fuel needed for those gas turbines. So, if this unit is a unit that will be base-loaded, carbon capture can play a crucial role in ensuring that that unit becomes a carbon-free asset that we need for the future. At EPRI, we're doing a lot of work in the space of CCS. We've been involved in a couple of demonstrations, particularly right now a lot of the work full-scale-wise has been around coal units. But we're continuing to move in and looking at opportunities for gas turbines and to continue to push the capabilities there further, so as we see this continuing to progress as in parallel, we're progressing the capability for utilizing low-carbon fuels.

Gas Turbines Evolving to Reduce Technical Barriers, But Go-to-Market Challenges Remain

During our visit to PowerGen 2025 in downtown Dallas, 

Jeffrey Benoit, Vice President of Clean Energy Solutions at PSM - a Hanwha company

, and Bobby Noble, Senior Program Manager, Gas Turbine R&D at EPRI, about gas turbine-equipped power plants, hydrogen- and ammonia-fueled 

, and other updates and advancements in the industry.

Jeff Benoit and Bobby Noble discuss the reliability and flexibility of gas turbines and how they satisfy many needs within power generation. 

Gas Turbines are Centerstage in the Energy Future 

TURBO: With increasing renewable energy penetration, how will existing gas turbine-equipped power plants be modified to support an intermittent grid?

 With the increased penetration of renewables, one thing we have to continue to focus on is the resiliency and reliability of the grid. Anytime you put an asset onto the grid that is not dispatchable and to the controls outside of your home, there are challenges. So, one of the things for gas turbines is filling that dispatchable need and being flexible and able to respond.

 For me, my company is responsible for retrofits, conversions, and upgrades for the installed fleet of gas turbines. So, one of the things that we're doing, and being asked for by our customers, is how to improve operational flexibility, how to improve efficiency, how to provide peaking power while maintaining emission compliance. All these technologies that we have can be manifested in products that can be easily dropped into these gas turbines, and you need that resiliency and the ability to modify the operational profile to balance renewables.

TURBO: What role will hydrogen- and ammonia-fired gas turbines play in a decarbonized future? What are the latest developments in these fields?

 Hydrogen and ammonia add to our optionality, which is going to be key as we look at the needs for decarbonization. These fuels act not only as fuel and a potential fuel replacement for gas turbines but also as an energy-storage mechanism. Coupled with energy storage and the energy released at dispatchable opportunities, these will continue to be an avenue to help us have that resilient and reliable future.

 Fuel flexibility with hydrogen, refinery off-gas, or ammonia is just a natural extension of the flexibility inherent in the gas turbines. We are focused on combustion retrofits that allow hydrogen consumption up to 100%. So, think about this: meeting emissions requirements, with the ability to operate on 100% natural gas all the way with a variable blend up to 100% hydrogen—these are products that we've spent years and years developing in our test facility in Germany to make sure that we're not going to cause any issues with the operation of the power plant. Of course, the other side of the equation is where is the hydrogen or ammonia going to come from?

Turbo Tour of EthosEnergy’s facility in Houston, Performance Center Director Daniel Tegtmeier offered his insights into the growth and evolution of remote monitoring, its advantages and challenges, and how the company seeks to establish partnerships in all things turbine- and plant-related.

Daniel Tegtmeier of EthosEnergy shares how remote monitoring has grown over the past several years and the advantages and challenges of virtual capabilities. 

Remote Monitoring: Growth, Advantages, and Challenges

Q: How has remote monitoring grown and evolved over the past several years? What’s next?

What started as very manual processes has now evolved to mostly automatic and automatically generated monitoring activities. What used to take operators and engineers days to troubleshoot problems is now an automated process via advancements in technology.

Q: EthosEnergy now has full start/stop capability on natural gas-fired power plants. What advantage does this offer your customers?

It’s more than just start and stop in thermal plants; we can start and stop renewable assets as well. Some of the advantages of remote operation are efficiencies. You could streamline the staffing model for intermittent thermal assets. Secondly, our package includes remote monitoring and advanced analytics that’s applied to the remote operation of customer assets, ensuring that they stay competitive in today’s market.

Q: What’s the biggest challenge facing the power industry as it relates to remote operations?

The biggest challenge is the reluctance to shift operating modes from mostly on-site human presence—operating the plant as designed—to remote facilities that apply humans to asset monitoring.

Q: What are EthosEnergy’s five- to 10-year goals?

The five-year goal is growth. EthosEnergy aspires to be a partner in all things turbine- and plant-related, and it’s not just the power industry. Turbines are used in a host of operations like LNG and oil and gas—we seek to be the largest partner for all those industries in the realm of rotating equipment. We want to increase partnerships and our OEM presence.

GE Vernova VPs Excited About Spin-Off, Tackling Climate Change

Q: After 130 years, GE spun off GE Vernova. What are your teams most excited about for its power segment?

 “My team is the same as the entire organization. We're excited about being part of a purpose-built company that is made up of 12 businesses operating as one and is focused on electrifying the world while decarbonizing it. We are uniquely positioned with those 12 businesses to cover a range of product portfolios, including power generation but also transmitting that power through the grid and optimizing that power as it flows through that grid. No other company can say, from front to back, that they're better equipped to face the challenge of the energy dilemma and decarbonize while we electrify.”

“It gets me up in the morning, just thinking about solving one of the world's greatest challenges, climate change, and working on great technologies, such as hydrogen combustion, carbon capture and storage, and direct air capture. That's what gets me up in the morning—that’s what gets my team up in the morning. We are going to be able to solve these problems, and we think of this as a great opportunity and a great responsibility.”

In Part 2 of our interview with GE Vernova's John Intile and Shane Long, the two VPs share what their teams are most excited about in light of GE Vernova’s recent spin-off.

GE Vernova's VP Talk Challenges with Energy Transition 

Long said: “First, let's describe the problem: We have to simultaneously electrify the world while decarbonizing it. The IEA estimates by 2040 we'll need 55% more electricity than we did in 2022. No notable goals have net-zero-carbon emissions by 2040 or 2050. So, one thing that's top of mind for challenges is just basic uncertainty—uncertainty in global policies with respect to carbon emissions; uncertainty in geopolitical tensions that exist in the world; and then uncertainty with how we can pay for this and economic policies that are needed to solve these challenges.”

Intile said: “After retiring most of the uncertainty, you start to put the plans into motion. When you think about the scale and capacity required to grow at the need of meeting the demands for what we see in 2040—project permitting, site readiness, etc.—everything it takes to get power generation up and running - it's no small feat. And that power generation is going to feed into a grid that, quite honestly, has a lot of questions about its stability. So, how do we think about challenges such as grid forming and how these electrons move from the source of generation to consumption—that's going to be a challenge that was not there in the past decade. With more renewable penetration—meaning that the power can fluctuate when the sun is not shining, when the wind is not blowing—we have to account for that, so do we have the right amount of inertia on the grid to account for that?”

GE Vernova's Shane Long Talks Gas Power Supply Chain

Long said: “Lean transformation has been the most impactful change for the gas-power supply chain in the last five years. Dating back to 2019, we embarked on a journey to transform the way we operate inside our factories as well as with our suppliers. Over the course of those five years, we've been focused on connecting operations together—creating a flow of our products through our factories, which allows us to highlight and isolate problems or inefficiencies. We’ve then organized our team around solving those problems and driving more efficiency in the day-to-day operations. Once we established flow, it allowed the team to understand where our problems were and gave them a chance to focus on root-cause understanding and eliminate those problems.

“Early on, the journey was predominantly focused inside our factory network. Over the last two to three years, we have extended that journey to include our supply base. Now we think about the solution from a value-stream perspective, so we're able to partner with our suppliers, who are critical to our success, and help them through the same steps of the journey, including waste identification, connecting operations, creating flow, and giving them a chance to problem solve, much like what we do in our factories. Now that we have the connected view of the value stream, those inefficiencies start to multiply, resulting in better safety, better quality, improved delivery, and cost productivity. We are seeing that start to emerge from our efforts over the last five years, and it's putting us in a better position to serve our customers.”
