Hydrogen has become the talk of the town in recent years, with its potential to revolutionize the transportation sector. The possibilities seem endless for this molecule, touted as a versatile and lightweight energy carrier.
It comes as no surprise that researchers like Karen Bridges from the University of Minnesota’s Humphrey School of Public Affairs are intrigued by hydrogen’s potential. In a high-level review paper commissioned by the Minnesota Freight Advisory Committee, Bridges highlights the viability of hydrogen as a carbon-neutral fuel alternative.
Bridges believes that hydrogen could be the “missing link” in the quest for decarbonization. Its energy density makes it suitable for heavy freight transportation over long distances. Additionally, hydrogen is easy to store, transport, and can be utilized in various industries such as aviation, international shipping, rail, and trucking.
However, there is one significant drawback when it comes to hydrogen: not all of it is truly “clean.” The process of obtaining hydrogen involves splitting existing molecules, either from natural gas or water, using electricity. The cleanliness of the hydrogen depends on the source molecule, the energy used in the splitting process, and the presence of a carbon capture method to mitigate byproducts.
The cleanest method is “green” hydrogen, produced by splitting water molecules using renewable energy sources. This method eliminates carbon byproducts, but its production cost is currently the highest. On the other hand, “blue” hydrogen splits natural gas molecules and incorporates a carbon capture system, striking a balance between cost and cleanliness. Finally, “grey” hydrogen also splits natural gas molecules but lacks a carbon capture system.
To make hydrogen an affordable and viable option for freight companies, the production of green hydrogen needs to be scaled up while driving down its cost. Regional and cross-sector cooperation is crucial in developing hydrogen infrastructure.
Thankfully, federal initiatives are already underway to support hydrogen advancement. The Clean Hydrogen Production Tax Credit program and the Regional Clean Hydrogen Hubs Program, dedicated to clean hydrogen production, storage, and transportation, are prime examples.
The future of hydrogen looks promising, with significant strides being made in policy and technology. As we witness these developments unfold, it is clear that hydrogen has the potential to transform the way we fuel our transportation systems.
