“…In addition, the worldwide percentage of energy produced by renewable energy is higher than in the U.S.A., reaching the 24% of the total [ 5 ], with the 58% purchased from hydroelectric source. Within this picture, hydrogen role is growing in importance as it can be used as energy vector and/or fuel mixed with the fossil ones [ 6 , 7 , 8 ]. Concerning hydrogen, one of the hardest issues to be solved is its efficient storage, which has been the subject of extensive research and multiple solutions are currently viable.…”

Influence of Chiral Compounds on the Oxygen Evolution Reaction (OER) in the Water Splitting Process

Results are presented concerning the influence on the water splitting process of enantiopure tartaric acid present in bulk solution. Stainless steel and electrodeposited nickel are used as working electrode (WE) surface. The latter is obtained by electrodeposition on the two poles of a magnet. The influence and role played by the chiral compound in solution has been assessed by comparing the current values, in cyclic voltammetry (CV) experiments, recorded in the potential range at which oxygen evolution reaction (OER) occurs. In the case of tartaric acid and nickel WE a spin polarization of about 4% is found. The use of the chiral environment (bulk solution) and ferromagnetic chiral Ni electrode allows for observing the OER at a more favorable potential: About 50 mV (i.e., a cathodic, less positive, shift of the potential at which the oxygen evolution is observed).

Summary One‐step electrochemical preparation of chlorine doped graphene coated electrodes was succeed by cyclic voltammetric method for the first time in the literature in this work. Because hetero atom and oxygen functional groups doped graphene‐based electrodes can improve the electrochemical performance of the battery with formed defects sides on the main structure of the electrodes, the modification of graphene‐based electrodes by chlorine and oxygen including functional groups such as ―Cl, ―ClO4, ―ClO3, ―OH, and ―C═O have been done by arranging of scanned potential in cyclic voltammetric treatment. The structural features of chlorine doped graphene electrodes were analyzed by scanning electron microscopic analysis. Chemical structures of the surface of the electrodes were elucidated by X‐ray photoelectron spectroscopy. Raman analyses were carried out to determine the optical properties of the electrodes. Chlorine doped graphene‐based electrodes were also used as positive electrode component of a vanadium redox battery for the first time in the literature. The electrodes showed great electrochemical performance as positive electrode materials of the battery.

“…The resultant hydrogen can have various applications, one of which is the consumption of hydrogen as a raw material by the petroleum industry . Moreover, it can be injected into existing natural gas infrastructure to produce a cleaner mixture called hydrogen‐enriched natural gas (HENG), which can be used in current applications without the need for additional modification. Furthermore, the hydrogen can be used to generate a renewable natural gas (RNG) after combining it with a CO 2 stream from biogas or any other CO 2 emitters (e.g., cement industry) in a methanation process .…”

Power-to-gas (PtG) is an evolving energy storage technique that can transfer surplus and intermittent renewable generated power into a marketable hydrogen, among other ancillary services for the electrical grid. This study provides a comparative assessment of blending 10 % corn-ethanol and using an electrolytic hydrogen supply via PtG on the well to wheel of gasoline fuel, based on Ontario's energy system. The analysis is performed using the GREET 1 model to investigate the energy and emissions results of the subject comparison. Consequently, PtG renewable hydrogen, when used for gasoline production, is found to decrease 4.6 % of the natural gas consumption of the gasoline cycle and, therefore, increase the renewable content of gasoline. Furthermore, the deployment of electrolytic hydrogen at the refinery results in minimizing gasoline carbon intensity by 0.15 kg CO 2 e per 100 km (0.5 g CO 2 e per MJ) of the fuel. When associated with the annual gasoline sales in Ontario, the use of electrolytic hydrogen can offer a reduction of 0.26 MT of greenhouse gas emissions yearly. Moreover, the hydrogen supply from the PtG method used for gasoline production may contribute to lowering VOCs, NO x , PM 10 , and PM 2.5 criteria air pollutants from the gasoline cycle, which cannot be achieved with blending corn-based ethanol. Therefore, the results of this paper support the inclusion of the PtG concept in renewable fuels regulations for petroleum fuels.
