The wide diffusion of fuel cell (FC) powered Zero-Emissions Vehicles (ZEVs) is stopped by hydrogen storage technological drawbacks, as high cost and low storage volume density.
This chapter provides an overview of the state-of-the-art in hydrogen safety as a technological issue only.
Therefore, the current paper can provide guidance to the technological research on hydrogen injectors in hydrogen internal combustion engine.
Chapter 20: Conclusion: technological challenges in hydrogen storageThe book discusses a wide range of issues from the types of hydrogen scenarios that may lay ahead, to the science and engineering considerations in designing stores and investigating novel hydrogen storage materials.
Both cylindrical and fusiform carbon nanoscrolls are hollow, and therefore, they might be of particular interest for many technological applications like hydrogen storage, drug delivery, novel composite nanomaterial fabrication, etc.
Q methodology, an established form of discourse analysis, was therefore undertaken in order to explore the competing visions and perspectives of experts working in the radical technological field of hydrogen production from waste.
"We still need major technological advances to ensure hydrogen can be affordable, safe, cleanly produced and readily distributed," said Sen. Lamar Alexander, R-Tenn., at the Monday hearing.
In this study, a technological specimen representative of hydrogen type IV high-pressure storage vessel is studied.
Hydrogen sulfide capture is an important technological challenge in energy and fuel industries, and reactive adsorption over zinc oxide is considered as a highly efficient one.
An equation was also developed, the analysis of which showed, that the hydrogen content cannot be reduced by technological methods below 21 ml/100 g.
In this context, we will propose techno-economic inputs and technological background information for hydrogen delivery pathways in later work, as the final paper of this serial study.
