Sustainable hydrogen generation and storage – a review

Abstract

This paper reviews the renewable hydrogen generation pathways, along with purification and storage technologies, and discusses the hydrogen economy and future prospects from an Indian context.

Investigation of Active Spots on a TiC@MnSe Nanocomposite: An Efficient Electrocatalyst for the Oxygen Evolution Reaction

“…10 In contrast to electrocatalytic water splitting, the photoelectrocatalytic and photocatalytic water-splitting approaches are slow in hydrogen generation and sessional dependent. 11 So, in essence of available options, electrocatalytic water splitting is a supercilious and attractive option. Predominantly, electrocatalytic water splitting is conducted under three types of electrolyzers, namely, alkaline, acidic, and solid oxide electrolyzers.…”

“…Mainly, three approaches are adopted for water splitting acknowledged as photoelectrocatalytic, photocatalytic, and electrocatalytic water splitting . In contrast to electrocatalytic water splitting, the photoelectrocatalytic and photocatalytic water-splitting approaches are slow in hydrogen generation and sessional dependent . So, in essence of available options, electrocatalytic water splitting is a supercilious and attractive option.…”

Hydrophilic amorphous Cr2O3 supported Co species toward efficient hydrogen production from ammonia borane under visible light irradiation

“…Hydrogen (H 2 ) as clean energy has attracted much attention owing to zero carbon emissions and high combustion value. 1–3 Ammonia borane (NH 3 BH 3 ) as a promising hydrogen storage material with high hydrogen content (19.6 wt%) can present the solution for the challenges of safe transportation and storage of H 2 . 4,5 The hydrolysis of NH 3 BH 3 (NH 3 BH 3 + 2H 2 O → NH 4 BO 2 + 3H 2 ) is considered a promising strategy to generate H 2 due to the mild reaction conditions.…”

Phyto‐synthesized ZnO/ZrO2 binary oxide as a new electro‐catalyst for water splitting application ZnO/ZrO2 for water splitting application

“…However, this manufacturing path not only increases the use of fossil fuels but also boosts CO 2 emissions globally. [11,12] Therefore, finding a clean, sustainable, and effective H 2 manufacturing route is urgently needed. Electrochemical water splitting for hydrogen and oxygen production is thought to be a promising method to provide affordable clean energy if renewable energy or surplus electricity is fully available.…”

“…It uses both H 2 O and CH 4 as the principal sources. However, this manufacturing path not only increases the use of fossil fuels but also boosts CO 2 emissions globally [11,12] . Therefore, finding a clean, sustainable, and effective H 2 manufacturing route is urgently needed.…”
