“…One of the above methods, the WE process, is a green energy method, which produces ultrapure hydrogen (≫99.999) but costs more than conventional methods . IEA (International Energy Agency) analysis shows that renewable energy’s cost of hydrogen production could fall 30% by 2030 . Although WE can solve environmental problems as a renewable energy production technology, the application of this method is still minimal .…”

The rising demand for fossil fuels and the resulting pollution have raised environmental concerns about energy production. Undoubtedly, hydrogen is the best candidate for producing clean and sustainable energy now and in the future. Water splitting is a promising and efficient process for hydrogen production, where catalysts play a key role in the hydrogen evolution reaction (HER). HER electrocatalysis can be well performed by Pt with a low overpotential close to zero and a Tafel slope of about 30 mV dec −1 . However, the main challenge in expanding the hydrogen production process is using efficient and inexpensive catalysts. Due to electrocatalytic activity and electrochemical stability, transition metal compounds are the best options for HER electrocatalysts. This study will focus on analyzing the current situation and recent advances in the design and development of nanostructured electrocatalysts for noble and non-noble metals in HER electrocatalysis. In general, strategies including doping, crystallization control, structural engineering, carbon nanomaterials, and increasing active sites by changing morphology are helpful to improve HER performance. Finally, the challenges and future perspectives in designing functional and stable electrocatalysts for HER in efficient hydrogen production from water-splitting electrolysis will be described.

“…There is a relevant synergy between the accelerated implantation of renewable energies and the production and use of hydrogen. Plans for the use of hydrogen have been developed in Australia [8,9], Brazil [10], France [11], Germany [12,13], Japan [14,15], The Netherlands [16,17], Great Britain [18] and USA [19]. The different strategies depend on the methods of producing hydrogen and the main uses of hydrogenation in accordance with the particularities of each country [20,21].…”

The unbridled use of fossil fuels is a serious problem that has become increasingly evident over the years. As such fuels contribute considerably to environmental pollution, there is a need to find new, sustainable sources of energy with low emissions of greenhouse gases. Climate change poses a substantial challenge for the scientific community. Thus, the use of renewable energy through technologies that offer maximum efficiency with minimal pollution and carbon emissions has become a major goal. Technology related to the use of hydrogen as a fuel is one of the most promising solutions for future systems of clean energy. The aim of the present review was to provide an overview of elements related to the potential use of hydrogen as an alternative energy source, considering its specific chemical and physical characteristics as well as prospects for an increase in the participation of hydrogen fuel in the world energy matrix.

“…136 There are many future energy roadmaps based on hydrogen which detail the construction of hydrogen generation facilities at the GW scale within the next 10 years. 137 The European Union has projected up to 40 GW of stationary electrolyser capacity by 2030 138 which will be difficult to meet given that the current production of iridium and platinum for PEM electrolysers could only support an estimated 3–7.5 GW annual manufacturing capacity. 139 In addition the stack life of an electrolyser is around 7–10 years, 136 therefore recovering the PGMs from the MEA will be critical in the future when hydrogen production plants at the GW scale are being considered.…”
