On September 16, 2024, the HYSKY Society hosted the 58th episode of HYSKY Monthly featuring industry experts Michael Lewison and Michael Maher from T.O. Viridi, as they shared their insights into the ethanol revolution and hydrogen infrastructure. The discussion, part of the HYSKY Monthly series of hydrogen aviation webinars, delved into using existing resources to foster a hydrogen-based energy landscape.
Ethanol vs. Methanol: The Safer and Ready Alternative
One of the central themes discussed was the choice between ethanol and methanol as carriers for hydrogen. Michael Lewison highlighted how ethanol emerges as the more favorable option due to its current availability and better safety profile compared to methanol, which poses toxicity risks. This makes ethanol a safer and more practical option for widespread adoption in hydrogen energy systems.
Strategic Production and Infrastructure Optimization
The abundance of ethanol infrastructure in the United States presents a unique opportunity for efficient hydrogen distribution, a point emphasized by both Lewison and Maher. This infrastructure can be leveraged for on-site hydrogen production and storage, especially in large-scale environments like airports. By integrating ethanol facilities, the transition to a hydrogen economy can be streamlined. Notably, ethanol also involves biogenic carbon capture, offering a potential net negative carbon process, enhancing its appeal from an environmental perspective.
Hydrogen’s Role in Sustainable Aviation
From an aviation viewpoint, hydrogen presents a promising path for sustainability. The discussion noted that hydrogen could play a pivotal role in aviation's future by being produced at airports using local resources like solar energy, as seen in places such as Denver. Despite challenges like seasonal snowfall, ethanol stands out as a key player in achieving sustainable aviation goals.
Addressing Infrastructure and Public Perception Challenges
However, the transition to a hydrogen economy is not without its hurdles. Electricity costs in regions like California pose challenges to adopting hydrogen solutions, as discussed by Lewison and Maher. The speakers underscored the necessity of innovative approaches to these obstacles, including maximizing local resources and enhancing transportation networks.
Public perception of hydrogen is another critical aspect. Making comparisons between hydrogen and alcohol—substances that are widely known—can help demystify hydrogen and promote its acceptance.
Embracing Hydrogen for a Greener Tomorrow
The journey to a hydrogen economy is challenging yet filled with possibilities for innovation. T.O. Viridi believes that by championing ethanol as a transitional medium, utilizing existing infrastructure, and fostering public engagement, hydrogen can become a cornerstone of our sustainable energy future.
