Quotation for Low-Pressure Energy Storage Container Project for Railway Stations

What are the high priority storage options for refueling stations?

Per DOE directive, we are focused on high priority storage options around the compressed gas, liquid fuel, and onsite store at refueling stations. The project team should revisit the models and seek more input from industry. This comment was specific to the MDV/HDV analysis, but we agree this is broadly true for all the analysis we conduct.

What type of container system is used for low-pressure storage?

For low-pressure storage (nominally 172 bar), the panel chose to use a U.S. Department of Transportation (DOT) International Standards Organization (ISO) container system based on Type 4 vessels. A system using Type 110 vessels had a similar cost, but a larger footprint.

Do railway systems need electricity and hydrogen?

Therefore, railway systems will be likely to need both the electricity and hydrogen , and a part of renewable electrical power needs to be transmitted through cables for train traction, while the other part of renewable energy can be converted into hydrogen for energy storage using power-to-gas (PtG) technology.

How is hydrogen stored in railway vehicles?

Hydrogen storage capacity in the investigated railway vehicles, Appendix A. When hydrogen is stored inside dedicated machine housings placed on locomotive frames of shunting locomotives, less storage capacity tends to be possible than on the roof of railcars.
