Hydrogen production using solar radiation

Operational Conditions Affecting Hydrogen Production by the Photoreforming of Organic Compounds using Titania Nanoparticles with Gold

“…Besides cleaner electrochemical processes, numerous production methods have been studied to look for a more sustainable production system such as thermochemical processes using biomass, gasification, and pyrolysis and biological processes by dark and photofermentation using bacteria and microalgae. If we consider solar energy as a front‐running clean, abundant, and secure energy source, some researchers have faced the increasing demand for energy by proposing a photocatalytic hydrogen production process as a way to store solar energy as chemical energy …”

“…However, one of the barriers to the expansion of the use of hydrogen is its current unsustainable production process,w hich is mainly based on fossil fuels;t he steam reforming of methane and the gasification of coal share 96 %o fthe world market.

Operational Conditions Affecting Formaldehyde and Formic Acid Formation as By‐Products of Hydrogen Production via Photo‐Reforming of Methanol Using Nanoparticles of TiO2

“…Photocatalytic hydrogen production process is a way to store solar energy in chemical energy using nano‐sized semiconductors . Titanium dioxide is the most widely used semiconductor for photocatalytic applications because it is stable, noncorrosive, harmless, abundant, inexpensive, and able to generate the water splitting reaction and photo‐reforming of several organic compounds …”

Solar power tower as heat and electricity source for a solid oxide electrolyzer: a case study

“…The concept of the high‐temperature steam electrolysis (HTSE) was first investigated in the 1980s within the project HOT ELLY by the German Dornier System in cooperation with the companies Lurgi and Bosch . Then, several companies and research institutes initiated HTSE activities, such as the Idaho National Laboratory (INL), Japan Atomic Energy Research Institute (JAERI), and Westinghouse Electric . The electrolyte for steam electrolysis is no more liquid but consists of a solid electrolyte of stabilized ZrO 2 ceramics, well known as solid oxide electrolyte .…”
