Discussion Overview
The discussion revolves around the feasibility of efficiently storing hydrogen as a solid for vehicle use, particularly in the context of a science fair project. Participants explore the theoretical and practical challenges associated with achieving solid hydrogen at extremely high pressures and the materials required for such storage.
Discussion Character
- Exploratory
- Debate/contested
- Technical explanation
Main Points Raised
- One participant, macfan, suggests that hydrogen can become a solid at 3,500,000 psi, potentially offering more power in less space for vehicle efficiency.
- Another participant argues that achieving such high pressures requires a diamond anvil cell and questions the practicality of storing solid hydrogen in useful quantities.
- macfan references a source claiming to solidify hydrogen and questions the validity of the initial skepticism.
- A participant clarifies that the term "solid" in the referenced source may refer to hydrogen being absorbed in a solid lattice rather than being in a true solid state.
- macfan inquires about the methods for pumping high pressure into a storage unit while maintaining low temperatures.
- Another participant questions the advantages of solid hydrogen over liquid hydrogen, suggesting that the solid form may not be denser.
- macfan reiterates their project question about creating solid hydrogen on a 1/10 scale.
Areas of Agreement / Disagreement
Participants express differing views on the feasibility of solid hydrogen storage, with some questioning the practicality and others exploring theoretical possibilities. No consensus is reached regarding the viability of the proposed project.
Contextual Notes
Participants highlight limitations related to the extreme pressures required, the materials capable of containing solid hydrogen, and the definitions of "solid" in the context of hydrogen storage.
