eHydrogenation: Hydrogen‐free Electrochemical Hydrogenation

open access: yesAngewandte Chemie International Edition, 2023
AbstractHydrogenation reactions are staple transformations commonly used across scientific fields to synthesise pharmaceuticals, natural products, and various functional materials. However, the vast majority of these reactions require the use of a toxic and costly catalyst leading to unpractical, hazardous and often functionally limited conditions ...

Metallic hydrogen [PDF]

open access: yesJournal of Physics: Condensed Matter, 2018
For over eighty years, scientists have been trying to produce lab-made metallic hydrogen, the holy grail of alternative fuels. In that process, diamond anvils must withstand pressures greater than those at the center of the earth—no mean feat. Recent research may have finally achieved hydrogen’s metallic state.

Hydrogen at the rooftop: Compact CPV-hydrogen system to convert sunlight to hydrogen [PDF]

open access: yes, 2018
Despite being highest potential energy source, solar intermittency and low power density make it difficult for solar energy to compete with the conventional power plants. Highly efficient concentrated photovoltaic (CPV) system provides best technology to

Hydrogen [PDF]

open access: yesMaterials, 2011
The idea of a “Hydrogen Economy” is that carbon containing fuels should be replaced by hydrogen, thus eliminating air pollution and growth of CO2 in the atmosphere. However, storage of a gas, its transport and reconversion to electricity doubles the cost of H2 from the electrolyzer.
