Climate change is an issue that scientists, engineers, politicians, and many others have been grappling with for decades now, but it’s much more than that. It's ever present in our lives.
Fundamentally, climate change is part of the dialogue of our future. With this podcast, Cutting Carbon, we’re sharing our thoughts on the factors at play today as well as the journey ahead.
We’ll be talking to scholars, technology experts, and industry luminaries to get their views on decarbonization. We’ll be providing you with the basics of what decarbonization is, the technologies behind it, why it matters, and how we can think about implementing these technologies and strategies into how we generate power.
Decarbonizing many sectors of the economy, including transportation and power, may require low or zero carbon fuels. Hydrogen is a popular favorite, and there are multiple technologies available that produce hydrogen for power generation applications. They are typically described by a color (grey, blue, green, red, pink, turquoise, white) instead of the actual production method. Jeff and Brian discuss these production pathways along with their challenges and requirements.
Hydrogen may be a fuel of the future, but there are multiple steps to developing a hydrogen economy. Once hydrogen is produced it needs to be stored and transported. Then there are the potential issues in the end use of hydrogen as a fuel that must be considered.
In this episode, Brian and Jeff welcome John Intile, VP of Engineering for GE Gas Power, for a discussion on the use of hydrogen as fuel for gas turbines. Since hydrogen has very different physical and chemical properties relative to methane (the main component in natural gas and LNG), John provides insights into GE's experience with hydrogen and potential impact to a power plant configuration. Additionally, the team discusses the implications to the transportation and storage of hydrogen for power generation.
Imagine operating a power plant on traditional fuels, like natural gas or LNG, but with reduced carbon emissions. This is the potential impact of post-combustion carbon capture technologies. These systems, when applied to power plants, can remove (or capture) large portions of the CO2 that would otherwise be emitted to the atmosphere.
Our guest, John Catillaz, Decarbonization Marketing Director for GE Gas Power, joins us for a discussion on this technology. John explains how this technology works, and provides the information on the broader context of carbon capture utilization and sequestration (CCUS).
The use of capture technologies to abate carbon emissions depends on our ability to use or store CO2. The good news is that the storage of CO2 has been ongoing for decades.
Our guest, Chris Consoli, a senior consultant at the Global Carbon Capture and Storage Institute (GCCSI) explains the geological science behind carbon capture. In this episode, Chris provides technical details, key statistics, and real world examples.

Have you ever wanted to hear about the decarbonization of power from the perspective of a company that develops both renewable and natural gas power projects? Here's the opportunity.
Jeff and Brian are joined by Tom Rumsey, SVP of External and Regulatory Affair, at Competitive Power Ventures (CPV). Tom provides his views on many facets of decarbonizing the power sector including policy, regional electric power systems, and technology.

The February 2021 winter storm in Texas that left millions of people without power was a tragedy. Brian and Jeff discuss what happened to both electricity supply and demand in Texas leading up to, and during the crisis.
Examining what happened provides an opportunity to reflect on how we might prevent similar situations from happening in the future, especially as we may be become more reliant on a few sources of electricity.

Global climate change is real. We have a limited time to take action to limit the impact and to prevent massive long-term global changes. Conversation with Brian Gutknecht, GE’s Chief Marketing Officer.
Carbon emissions are prevalent in multiple sectors, not just power. Industry, transportation and agriculture all contribute to global CO2 emissions. Guest: Neva Espinoza, Vice President, Energy Supply and Low-Carbon Resources at the Electric Power Research Institute (EPRI).

Decarbonizing power is a team sport. Today, there are still a billion people in the world without electricity. By 2050 the world is expected to need ~42,000 Terawatt Hours of electricity, adding about 400 TWh of additional power every year; that’s twice as much electricity as California generates today. Can this all be done by renewables? We hope that the continued growth of renewable power generation will lead to wind and solar being 50% of total electricity generation by 2050. But where will the other 50% come from? In this episode Brian and Jeff explore this paradox with Vic Abate, GE Chief Technology Officer and the CEO of GE Research.
What do terms like carbon neutral, carbon negative, zero carbon mean? What are the implications of various scope levels of emissions? What is carbon intensity? Want to know more? Jeff Goldmeer and Brian Gutknecht explain what these key terms mean and why it matters.
We don't have to invent new technology to begin to combat climate change today. Gas-fired generation is flexible, affordable, reliable, and produces less than half CO2 of coal, while coal-to-gas switching represents a fast and effective win for emissions reduction. But what technology options exist for gas turbines to reduce carbon emissions. Jeff and Brian talk about the use of hydrogen as a power generation fuel and the potential for carbon capture technology to be applied to power plants.
Did you know that a gas turbine sucks in enough air to fill a Goodyear blimp in ~10 seconds? Our guest Dr. Jacqueline O’Connor, Director of the Penn State Center for Gas Turbine Research, Education, and Outreach at The Pennsylvania State University, explains the main components of a gas turbine and how these amazing machines manage one of the most extreme environments that human engineers have developed.
