**Key Takeaway:** In-depth understanding of the state and potential of hydrogen technologies, especially PEM electrolyzers and fuel cells, in transitioning to sustainable energy.

Host Tyler Campbell provides a comprehensive overview of the role of electrolyzers and fuel cells within the hydrogen sector, featuring insights from industry leaders at Accelera by Cummins. The episode takes place live from CERAWeek, a prominent energy conference.

Tyler is joined by Dr. Andreas Lippert, VP and General Manager of Electrolyzers, and Allison Trueblood, General Manager of Fuel Cells and Hydrogen Technologies at Accelera. The conversation begins with an introduction to Accelera, explaining its focus on the zero-emissions technology sector and its strategic acquisitions and joint ventures aimed at advancing decarbonization technologies.

Allison discusses the development of Accelera’s fuel cell technologies, including the details of their growth and advancements from low-pressure fuel cells to their upcoming fourth generation of higher power cells. She explains how the fuel cells are integrated within broader vehicle systems to enhance efficiency and performance.

Andreas describes the technological specifics of electrolyzers, focusing on proton exchange membrane (PEM) technology and its advantages for integrating with renewable energy sources due to its rapid response times and compact size.

Throughout the episode, both guests discuss the commercial applications of their technologies, particularly in heavy-duty transportation and industrial sectors, emphasizing the importance of hydrogen as a diverse tool for energy transfer and storage. The dialogue also covers the market dynamics affecting the adoption of hydrogen technologies, such as infrastructure development, regulatory incentives, and the total cost of ownership.

To conclude, the episode engages a broader discourse on how the hydrogen industry can play a crucial role in global decarbonization efforts, with a particular emphasis on the "hard to abate" sectors. Andreas and Allison outline the strategic directions of Accelera by Cummins, highlighting their commitment to innovation and partnership within the hydrogen and broader zero-emission technology spaces.

By the end of the podcast, listeners gain a clear understanding of the current state and exciting future of hydrogen technologies, particularly within the realm of PEM electrolyzers and fuel cells, and the critical role these technologies play in the transition to sustainable energy systems.
