Research Project Description:
A major challenge of our time is to decrease the level of greenhouse gases to reduce global warming. Over ninety percent of global hydrogen is produced through a process of steam methane reforming (SMR) of natural gas which is contributing nearly 900 million tons of carbon dioxide into the atmosphere. Today, there is a need for sustainable innovations. Here at UCSB, the Mike Gordon Lab is studying a clean energy solution known as methane pyrolysis to produce hydrogen gas in a sustainable way. Methane pyrolysis does not involve the release of carbon dioxide into the atmosphere but involves the decomposition of methane (natural gas) into hydrogen gas and solid carbon. We are studying conditions that influence the rate at which methane is converted to hydrogen and carbon. Specifically, improved FTIR reference standards were established during my work in the Gordon lab and more efficient experimental design was accomplished that will enhance future work in this project. By improving the efficiency of methane pyrolysis, our work contributes to a more sustainable future.

Curriculum Project Title:
Curriculum Project Description:
In a classroom setting, students participate in experiments to explore the phenomena of using water as a fuel in a fuel cell car. These experiments involve electrolysis, where water is split into hydrogen and oxygen using an electric current. The generated hydrogen is then utilized in a hydrogen fuel cell, which combines it with oxygen to produce electricity, powering the fuel cell car. Throughout the unit, students engage in sense-making activities, including whiteboard modeling, to deepen their understanding of hydrogen as a clean energy source. By actively participating in these experiments and discussions, students gain valuable insights into the potential of hydrogen as a sustainable fuel for transportation.
