“…The potential of solar energy is abundant to be utilized and combined with biomass, water, geothermal and of course hydrogen production through electrolysis known as Alkaline Elecrolyser (ALEL), Proton Exchange Membrane (PEM), and Solid Oxide Electrolyser (SOE) [26]. The potential for electrical energy in Turkey mostly comes from hydropower because there is a high water flow rate of around 202 m3∕s so it is possible to produce 108.53 kt of hydrogen per day [27].The basic material for hydrogen production in Turkey is water from sea water, lakes, and river water [28].…”

The use fossil energy consumption in Indonesia is increasing along with population growth and industrial development. Fossil energy oil and coal can produce greenhouse gas emissions and environment pollution. The largest producer of CO2 emissions comes from exhaust gases in the production process and motor vehicles. Indonesia's energy mix target in 2025 is around 23% from New and Renewable Energy (NRE). Given the importance of using NRE, Indonesia is starting to look for alternative energy that is environmentally and sustainable, like hydrogen energy. Green hydrogen technology has the potential to be developed in Indonesia. Hydrogen production processes commonly carried out are through the electrolysis of water, methanol, and biomass. The use of hydrogen can be applied to motor vehicles and power plants. Hydrogen can reduce greenhouse gas emissions. However, Indonesia has problems in developing green hydrogen technology, one of which is the high production cost, so it requires other parties to develop it.

“…Hydrogen contributes to different forms of energy, such as generating electricity via fuel cells and fuel for gas turbines or internal combustion engines. Hydrogen can be generated from many sources using different methods and technologies, including fossil fuels and renewable energy sources. , Global demand for hydrogen is generated by approximately 48% of natural gas, 30% by heavy oils and naphtha, 18% by coal, and the remaining 4% is produced by the electrolysis method of water. − Among these methods, hydrogen production via electrolysis of water has attracted the attention of many researchers in recent years due to its important advantages in both alkaline and acidic environments. − However, the overpotential in the electrodes, which is an important issue in water electrolysis, is a disadvantage due to high energy consumption and production costs. These disadvantages can be solved by the development of new cathode and anode electrode materials with high electrocatalytic activity, high corrosion resistance, low overpotential, and a large active surface area in hydrogen evolution reactions (HERs) and oxygen evolution reactions (OERs). − The development of new and low-cost electrode materials with high kinetic activity and good electrical conductivity is important to reduce energy losses in electrochemical applications.…”

Additive manufacturing has been a very promising topic in recent years for research and development studies and industrial applications. Its electrochemical applications are very popular due to the cost-effective rapid production from the environmentally friendly method. In this study, three-dimensional (3D) printed electrodes are prepared by Ni and Co coatings in different molar ratios. Different Ni/Co molar ratios (x:y) of the Ni/Co/x:y alloys are prepared as 1:1, 1:4, and 4:1 and they are named Ni/Co/1:1, Ni/Co/4:1, and Ni/Co/1:4, respectively. According to the results, when the 3D electrode samples are coated with Ni and Co at different molar ratios, the kinetic performance of the NiCo-coated 3D electrode samples for hydrogen evolution reaction is enhanced compared to that of the uncoated 3D electrode sample. The results indicate that the Ni/Co/1:4-coated 3D electrode has the highest kinetic activity for hydrogen evolution reactions (HERs). The calculated Tafel′s slope and overpotential value (η10) for HER are determined as 164.65 mV/dec and 101.92 mV, respectively. Moreover, the Ni/Co/1:4-coated 3D electrode has an 81.2% higher current density than the other electrode. It is observed that the 3D printing of the electrochemical electrodes is very promising when they are coated with Ni–Co metals in different ratios. This study provides a new perspective on the use of 3D printed electrodes for high-performance water electrolysis.

“…Steam reforming is one of the major technologies for the industrial production of hydrogen. However, the accompanied emissions pose concerns for the environment [ 2 , 3 ]. Water, as the simplest of the molecules, contain 11.11 wt % of hydrogen, which along with its natural abundance makes it the pivotal theme of enormous research undertaken for hydrogen production by using either the electrochemical or the photocatalytic pathways [ 4 , 5 ].…”

The over-dependence on fossil fuels is one of the critical issues to be addressed for combating greenhouse gas emissions. Hydrogen, one of the promising alternatives to fossil fuels, is renewable, carbon-free, and non-polluting gas. The complete utilization of hydrogen in every sector ranging from small to large scale could hugely benefit in mitigating climate change. One of the key aspects of the hydrogen sector is its production via cost-effective and safe ways. Electrolysis and photocatalysis are well-known processes for hydrogen production and their efficiency relies on electrocatalysts, which are generally noble metals. The usage of noble metals as catalysts makes these processes costly and their scarcity is also a limiting factor. Metal nitrides and their porous counterparts have drawn considerable attention from researchers due to their good promise for hydrogen production. Their properties such as active metal centres, nitrogen functionalities, and porous features such as surface area, pore-volume, and tunable pore size could play an important role in electrochemical and photocatalytic hydrogen production. This review focuses on the recent developments in metal nitrides from their synthesis methods point of view. Much attention is given to the emergence of new synthesis techniques, methods, and processes of synthesizing the metal nitride nanostructures. The applications of electrochemical and photocatalytic hydrogen production are summarized. Overall, this review will provide useful information to researchers working in the field of metal nitrides and their application for hydrogen production.
