Klaus Brun and Rainer Kurz break down the myth that electrification and electric-motor drives are decarbonized. 

TurboTime Podcast: Debunking Machinery Decarbonization Myths

In this interview with Scott DeNeale, a Water Resources Engineer at Oak Ridge National Laboratory, we discuss the lab’s current research projects in hydropower and trends such as low-head and modular designs and metal additive manufacturing to manufacture Francis turbines. The lab is working on a lot of exciting work, and even though hydropower has been around for 150 years, DeNeale said there is a lot of opportunity to complement new generation with environmental compatibility.

An interesting fact is that only 3% of the more than 90,000 damns in the United States use hydropower. Why? Listen to find out!

TURBO: Can you tell us a little about Oak Ridge National Lab?

 Oak Ridge National Laboratory is the largest multi-program science and technology laboratory in the United States. It's managed by UT Battelle but is owned by the U.S. Department of Energy. As part of my research, I do a lot of work for hydropower. The research and development that I do touch on a lot of different things. We look at grid integration, markets, reliability, performance, hydrology and hydraulics, water management, biodiversity and ecosystem science. We look at technological advancement as well.

TURBO: What recent advancements have you seen in turbomachinery used in hydropower technology and pumped storage hydropower technology?

 Conventional hydropower—what we would speak to is the age of the big dams is over, so a lot of what we're looking at is retrofitting existing dams, replacing units, or adding new units to existing dams. And there's an area looking at canals and conduits as well. So, some of the advancements that I've seen are really geared toward the existing infrastructure, which has largely low-head or low-pressure potential. It’s a little bit different design that is used to capture that design point. Another area is modular technologies and standard technologies. Conventionally, a lot of turbines are custom-built, so the ability to have a standard design that could be plug-and-play has been of interest. We've had some research over the past 10 years related to that, working with industry on advancing their concepts as well. 

For pumped storage … I would refer you to a report from some of my friends at Argonne National Laboratory. They have done some great documentation of innovations—a lot of it's conceptual for pump storage but some cool innovations there. However, there has been no new pump storage since 2012. And, even with that, that was a very small project. So, since the mid-nineties, there really hasn’t been much of anything in terms of new pump storage, but there is a great demand for it.

Scott DeNeale of Oak Ridge National Lab shares trends in hydropower—from modular designs to additive-manufactured Francis turbines. 

TurboTime Podcast: Modular and Low-Head Designs are Trending in Hydropower 

In this episode of the TurboTime Podcast, Myth Busters Klaus Burn of Ebara Elliott Energy, and Rainer Kurz of RKSBenergy LLC, discuss root-cause analysis (RCA), including what it is, the philosophy and methodologies behind it, what actions should and should not be taken, and more.

Brun said: “RCA, some folks call it root-cause failure analysis, looks at something that failed: Your machine had a catastrophic failure, or you’re missing performance by a percent or two—something is not as you would expect in a compressor or gas or steam turbine, and you want to figure out what it is. So, you perform an RCA based on certain symptoms. In most cases, RCA starts with a review of the machine’s operation that may have preceded the failure and in some cases a metallurgical investigation, which is one of the best indicators as to what failed. It can indicate it was high-cycle fatigue, sudden overload, corrosion or erosion, for example. Then you figure out what excitation may have caused the high-cycle fatigue or what in your process gas may have caused corrosion or erosion.”

Kurz said: “In a way, this is a bit like a detective story. You find something failed, aka the dead body, and then you gather evidence. One of the key things in root-cause failure analysis is that you not only gather evidence, but you also document it. One of the key problems when these reports are written is you have a failure in 2015, for example, and you conduct an RCA, and the next similar failure isn’t for another 10 years. (These events don’t happen that often.) And if you haven't documented what you did for the first one, you can’t use it as a starting point.”

Klaus Brun and Rainer Kurz discuss root-cause analysis—what it is, its methodologies, and why it’s so important to managing turbomachines.

TurboTime Podcast: Root Cause Analysis with the Myth Busters 

During this episode of the TurboTime Podcast, Klaus Brun and Rainer Kurz discuss how hydrogen is transported and its use as an energy carrier. They then discuss how ammonia is produced, its advantages and limitations, and for what industries it’s a suitable solution.

“We’ve previously talked about hydrogen in some of our Myth Buster podcasts and how it’s relevant to a decarbonized energy economy as an energy carrier. Unfortunately, hydrogen itself has a lot of nasty characteristics: it's hard to compress, highly flammable, as a gas it’s not easy to deal with, etc. From a transportation and storage perspective, it leaks, has many safety issues, causes hydrogen embrittlement, etc., making it difficult to transport.”

“Making ammonia is nothing new. We know how to how the process works, but it is an energy-intensive process. But ammonia is a very toxic gas. It causes skin burns rapidly if you touch it in liquid form. In vapor form, even at less than 100 PPMs, it’s very irritating, so it creates a lot of issues from the handling perspective.”

In this episode of the TurboTime podcast, Myth Buster Klaus Brun and Rainer Kurz discuss ammonia. 

TurboTime Podcast: Ammonia with the Myth Busters

This episode of the TurboTime podcast features an onsite interview from our Turbo Tour of EthosEnergy’s Light Gas Turbine and Performance Center Facility in Houston. Assistant Editor James Cook talks with Daniel Tegtmeier, Director of EthosEnergy's Performance Center, about remote monitoring and operations, the changing energy landscape, and the benefits of remote start/stop and virtual capabilities.

Q: How does remote monitoring keep simple-cycle assets viable in a market focused on renewable energy?

 If you think about a machine built 20+ years ago and its efficiency, it still has a place in the market when competing with renewables. It’s not like it used to be though—these units used to run wide-open, 24/7. They’re now intermittent assets competing with renewables and zero-cost fuels, but once the wind stops blowing and the sun stops shining, that load is gone.

These are simple-cycle configurations, so they can come online quickly and be at 100 - 120 MW in less than an hour. So, you’re going to staff a facility 8,000 hours per year in case they call you up? That’s part of what we do and the justification for remote operations—you need the intermittent load from simple-cycle assets in rapid fashion, but you can’t afford to staff these places full-time.

Q: In addition to that justification, are there any safety improvements delivered through remote start/stop and control capabilities?

 Economics seems to drive most decision processes behind whether you’re remotely operating a facility or not; however, there’s a huge safety aspect. You don’t need people there 24 hours a day around equipment with a lot of pent-up energy, so exposure levels drop dramatically. For the most part, these machines are designed so well and over-engineered from day one that they’re conducive to [remote monitoring].

In this episode of the TurboTime podcast, Daniel Tegtmeier, Director of EthosEnergy’s Performance Center, talks about remote operations and monitoring. 

TurboTime Podcast: Remote Monitoring with EthosEnergy

In this episode of the TurboTime podcast, Klaus Brun and Rainer Kurz talk about turbine degradation. They define terms such as fouling, corrosion, erosion, and rubbing and dig a little bit into what causes degradation, how it can be measured and minimized, and the difference between recoverable and non-recoverable degradation.

Burn explained: “A gas turbine system consists of a compressor, combustor, and one or several turbines, so degradation at its highest level is simply measured by what power output and efficiency to expect under certain operating conditions from a new machine and how much less power and less efficiency do you get after that machine has been running for thousands or tens of thousands of hours. The primary measurement is really on a macro level.”

During this episode, the Myth Busters break down the many terms associated with degradation, what components degrade, how it can be measured and minimized, and more. 

TurboTime Podcast: Turbomachine Degradation with the Myth Busters

In this episode of the TurboTime Podcast, we talk with Giuseppe Tilocca, Scientific Officer at ETN Global, a non-profit member association in the gas turbine technology space. ETN Global’s recent global report, 

Decentralized Energy Systems: Toward Carbon-Neutral Energy Solutions for Gas Turbines

, compares decentralized systems to centralized heat and power units and highlights its advantages—including modularity, the possibility to exploit waste heat avoiding energy transmission losses, and reducing energy distribution costs. Tilocca reviews these advantages in detail, as well as trends and emerging market opportunities, and he dives into gas turbines and how they fit into decentralized energy systems.

“Considering this specific report, we all know that the energy sector is transforming very quickly, and it's mainly driven by the increasingly high share of renewable energy sources,” Ticolla said. “In this scenario, which is dominated by variable sources whose daily, weekly, and seasonal flexibility are set to go dramatically, to meet the system requirements while accomplishing the ambitious decarbonization goals, we need to support traditional centralized generation with a mix of the centralized components.”

So, how does ETN Global define decentralized energy systems, and what are their advantages?

“Historically, we established centralized energy systems, meaning large plants located far from consumers,” Tilocca explained. “The reason behind it is merely economy of scale and efficiency, so it is cheaper to have one big plant than many small ones; however, with the increasing integration of variable renewable energy sources, which are inherently decentralized, we now need to adapt our infrastructure and incorporate technologies that are traditionally used for centralized energy. By definition, a decentralized energy system is located close to the consumption nodes—so on the end user side of the network—and therefore it's connected to the distribution grid rather than the transmission grid. The advantages of a decentralized energy system are mainly modularity, the possibility of exploiting waste heat, and a positive contribution to stability. In particular, one of the main advantages of being close to consumption nodes is avoiding transmission and distribution losses and also costs compared to centralized generation. Centralized energy systems are pivotal in meeting the pillars of the energy trilemma, which stress the principles of affordability, security, and climate neutrality and hence it aligns with the requirements for the transition toward 2030 but also 2040 and 2050.”

ETN Global’s Scientific Officer, Giuseppe Tilocca, talks about the association’s recent report on decentralized energy systems—their advantages and challenges, trends, and where and how gas turbines fit in.  

TurboTime Podcast: Decentralized Energy Systems with ETN Global 

In this episode of the TurboTime Podcast, the Myth Busters discusses the role of turbomachinery in energy transport and storage, including how gas turbines maximize energy density. They dive into various forms of energy storage—including batteries, hydrogen, and mechanical and thermal energy—for various energy sources such as wind, solar, fossil fuels, etc., and more.

During the energy transport and conversion processes, for example in the case of hydrogen, there are significant energy losses. The lowest losses are with coal, then oil and fossil fuels. As a result of these losses, “Hydrogen is a viable solution for storage, but it’s not a great solution to power a large-scale electric power plant by itself,” Kurz said.

Really, energy comes down to sustainability, affordability, and sustainability of supply – and in this equation, renewables are typically intermittent and not a reliable full-time source of energy.

So where does turbomachinery fit into all of this?

“From a turbomachinery perspective, if you exclude electric—because as Rainer said, it's not always applicable, as you can’t transport energy from Venezuela to Florida along an electric line—then you have to convert your energy stored material, be it natural gas, oil, coal, or from an alternative source then you have to convert it into hydrogen or ammonia or something else, and then transport it,” Brun explained. “All these convergent processes utilize turbomachinery. We have maybe 100 years of experience transporting oil in pipelines and ships and trucks and that involves a lot of pumping—we're very good at pumping – it’s very efficient. We also have about a similar amount of time compressing natural gas, which over the last 40 - 50 years we've used a lot more centrifugal compressors for transporting natural gas. Now we're running into the challenge of sustainable alternative energies where basically you're saying, ‘OK, I'm going to take my wind and solar electric and convert them to let's say hydrogen or ammonia or dimethyl ether or methanol—there are a lot of fluids that you can make from electricity that are energy carriers—but then they have to be transported. Hydrogen is the lightest gas (We had a previous podcast where we talked about the challenges of 

). Similarly, ammonia is a liquid that has to be transported at slightly refrigerated temperatures, and it brings its own challenges because it's highly poisonous and very corrosive to a lot of materials. Dimethyl ether is not that hard to transport—it’s similar to diesel—but it's very expensive to make. Methanol is also highly poisonous. So there are a lot of other challenges that you now face with these energy carriers that you worry about when transporting your original form of energy to the end user.”

Klaus Brun and Rainer Kurz dial into energy storage and transport—why they are necessary, how turbomachinery fits into these processes, and more. 

TurboTime Podcast: Energy Transport and Storage with the Myth Busters 

Myth Busters Klaus Brun and Rainer Kurz join the TurboTime podcast to chat about additive manufacturing. They dive into its history in the industry, its advantages as a viable technology, its limitations, and new advancements that could drive the technology further.

Brun explained: “About 40 years ago, additive manufacturing technology started coming out based on using materials such as polymers and resins that were heated up and layered on top of each other using some kind of robotic arm or plotter that in the 3D space. It wasn’t all that relative from a turbomachinery perspective at the time because yes, you could use that to make a mold for a cast, but other than that, it wasn’t realistic. About 20 years ago, we started seeing additive manufacturing using metals. There are a number of techniques, but the most popular ones are direct metal sintering or selective metal-laser sintering—these techniques are when you have a layer of metal and a heat source, and you put the heat source on the powder-metal layer to create a 3D geometry in 3D space. That technique has developed over the last 20 years—it came out with lots and lots of promises, some of which held up while other promises didn't hold up."

“From a turbomachinery perspective, there are many parts in a compressor, for example, or a gas or steam turbine, that are relatively standard pieces; you would probably not use additive manufacturing for those pieces because they're always the same, so you would cast them or quickly machine them. But then there are certain pieces that are either very intricate in geometry, so they require many smaller pieces to be put together or that are customized like impellers for centrifugal compressors. So here, theoretically, additive manufacturing should have an advantage because additive manufacturing provides you with the potential to build customer parts.” 

What’s the history of additive manufacturing, how is it used to manufacture turbomachines, and does it really have a future in the turbo industry? Find out more from the Myth Busters in this episode of the TurboTime Podcast. 

TurboTime Podcast: Additive Manufacturing with the Myth Busters 

Myth Busters Klaus Brun and Rainer Kurz join the TurboTime podcast to talk about turbomachinery factory and field testing—why are turbomachines tested, what’s standard, what’s extra, are the costs really worth it, uncertainty versus accuracy testing, different types of compressor-performance tests, how to test a gas and a steam turbine, and when is a full-string test necessary?

Brun explained: “When you make a machine of any kind, before delivering it to a customer, you want to make sure it actually functions, so standard tests are performed and then there are additional tests that some customers may require. Complex turbomachines—compressors, gas turbines, steam turbines, and even pumps—require some kind of factory testing to make sure the machine meets the basic functionality, it doesn't fly apart, and it performs at a certain level. From there, it gets a little more complicated, as each machine is different. For example, a gas turbine performance test can be performed in the factory or the field. In the factory, a prescribed test by API 616 could be used.

“A field test is a fundamentally different test where the machine is already installed, commissioned, started up, and sent to some engineers or technicians in the field to test under the conditions that may not necessarily be identical to the conditions that the machine was originally designed for or contractually agreed to or under factory testing conditions, so it's a more challenging test.”

In this episode of the TurboTime podcast, Klaus Brun and Rainer Kurz discuss turbomachinery factory and field testing—what they are good for, cost, and more.

Dr. Adolfo Delgado, Associate Professor of Mechanical Engineering at Texas A&M University’s Turbomachinery Laboratory, guided the 

 team through the lab, located in College Station, Texas, during our visit last month.

During our tour, he spoke about the latest research being conducted on rotating equipment systems and components and relevant trends and changes. According to Delgado, the industry’s most prevalent trend is transitioning toward high-power density machines, which the Lab’s component-level testing addresses.

Adolfo Delgado of Texas A&M’s Turbomachinery Laboratory says component-level testing and development have significant impacts on the industry as a whole.

Texas A&M’s Dr. Delgado Talks Component-Level Testing, Power Density Trends

TURBO: What improvements or research have been applied to rotating equipment, rotor dynamics, pumps, etc., at the Turbo Lab?

There are a number of developments and improvements that have been made over the years. We constantly work with our sponsors to understand the industry’s needs and how we can help improve their equipment. In terms of what we do here, we’ve mainly worked with components and have improved bearings, seals, and dampers. These are components that go directly into the machines and have a significant impact on the industry.

TURBO: What trends are you seeing in the rotating equipment space?

A constant trend that we’re seeing in the industry is increasing power density, and everything we do in terms of improving machinery is toward that goal. We work at a component and system level to find ways to improve power density. Another trend we’re seeing is high-power density CO

 for power generation, and it’s pushing the need for high-power density machines.

TURBO: What changes have you seen in rotating equipment in the past 3 – 5 years?

The main change we’re seeing in the rotating equipment field goes, again, toward having machines that can increase their power output while maintaining the size or shrinking the machine and maintaining the same power output. These initiatives require new mechanical components that are able to withstand high velocities or high speeds, as well as high forces. We may have to revisit some of these mechanical components.

In our final video from PowerGen 2025 with Jeffrey Benoit, Vice President of Clean Energy Solutions at PSM - a Hanwha company, and Bobby Noble, Senior Program Manager, Gas Turbine R&D – EPRI, the duo talks about the future of and what a decarbonized electric grid may look like, how OEMs are answering the call to create more power to satisfy demand coming from data centers, and availability versus sustainability.

Bobby Noble of EPRI says gas turbines are “well sought after” thanks to data center power demands and shifts in the energy portfolio mix. 

A Decarbonized Electric Grid is a Mix of Gas Turbines, Low-Carbon Fuels, Renewables

TURBO: In 10 years, what may the decarbonized electric grid look like?

 Ten years from now seems like a long time, but it's really not. Many projects take five to 10 years to develop and actually come full circle. It's one of those deals where, 10 years from now, we really need to start today. We're seeing capabilities being extended for utilizing low-carbon fuels, and we are starting to see some of these examples. When we think about the mix and what the future looks like, we have to think about gas turbines, low-carbon fuels, and carbon capture. Still, we also need to think about how renewables will continue to grow—wind and solar— and energy storage options and how those play into the mix. Lastly, nuclear, advanced nuclear, and small modular reactors —all these advancements that we need to be working on and focusing on today must be part of that mix in the future.

Gas turbines are playing an even more crucial role in ensuring the reliability and flexibility of our power-production landscape and portfolio in the United States. When we look at decarbonization on an overall basis, tremendous quantities of renewables are being put in place that can destabilize the grid. And gas turbines can provide that underpinning of reliability. Battery storage will also be very important in handling the microvoltage variations in various parts of the grid. Hydrogen for power production will be enabled mostly by the oil and gas industry. Here we are in Dallas, but right here in Texas, there are tremendous investments by the oil and gas industries and by those moving hydrocarbons, ammonia, and natural gas around. This is where I believe the genesis of the decarbonized power for gas turbines is going to happen.

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

Conference Coverage

Jim Crouse, President and CEO of Capstone Engineered Solutions, and Bert Warner, Director of Commercial Business Development at the Propane Education & Research Council (PERC), shared at POWERGEN 2025 the advantages and specifics of propane-powered machinery, its availability via widespread transportation infrastructures, and how it compares to alternative/traditional fuels.

TURBO: What advantages do propane-powered turbomachines have over traditional, natural gas-fired power generation?

Propane is a great fuel because of its ease-of-storage, portability, and ease to refill. We’d see it as a replacement for diesel, where we could include a propane storage and supply system with a turbine or engine. This makes it easy for customers to deploy and use the technology, almost as easy or as easy as using or renting a diesel generator set.

TURBO: Are there examples of large-scale propane-fired options that use turbomachinery? If so, what are they and how do they work?

We’ve done several large-scale multi-MW projects in places like Fiji with Fiji Water. In the Caribbean, there’s a number of propane liquefied petroleum gas-fired combined heat-and-power systems. We also have smaller systems in the hundreds of kW’s—these are readily available as well.

TURBO: On the supply side, how does propane’s availability and transportation infrastructure compare to natural gas, ammonia, or hydrogen?

Propane’s flexibility is that you can have it delivered wherever you want. You aren’t beholden to where the existing lines are, and you can create your own pathway for deliver. It’s overly abundant and we’ve got more of it than we could ever use. The fact that we can take it and transport it anywhere gives propane a great advantage.

Bert Warner of PERC and Jim Crouse of Capstone discuss propane’s greatest benefits: ease of deployment and transportation infrastructure.

Propane Advantages: Availability, Portability, and Flexibility

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.
