This paper presents a day-ahead economic optimization scheduling model for Regional Electricity–Hydrogen Integrated Energy System (REHIES) with high penetration of renewable energies. The electricity–hydrogen coupling devices are modelled energy storage units and Insensitive Electrical Load (ISEL). proposed objective function is able to capture the maximum benefits REHIES in terms can be summar...

Green methanol and green ammonia produced by renewable electricity electricity-based hydrogen become the backbone for a defossilised global chemical industry.

Hydrogen can be produced from fermentation of sugars in wastewaters, but much of the organic matter remains in solution. We demonstrate here that hydrogen production from a food processing wastewater high in sugar can be linked to electricity generation using a microbial fuel cell (MFC) to achieve more effective wastewater treatment. Grab samples were taken from: plant effluent at two different...

We are developing a novel high-efficiency, high-temperature steam electrolyzer. Although water or steam electrolysis is well known to be one of the cleanest ways to produce hydrogen, widespread utilization is hindered by high operational costs because of high electricity consumption. To decrease the electrical power input requirements in electrolysis, our approach uses natural gas as an anode d...

Introduction The use of hydrogen as a clean and sustainable fuel depends on an efficient and inexpensive method of producing the gas. Currently, most hydrogen is produced from steam reformation with hydrocarbons, where water splitting (hydrolysis) is performed by reacting steam to carbon-based fuels. To avoid the use of hydrocarbons and greenhouse gas emissions, hydrolysis is also possible thro...

The development of hybrid systems of renewable electricity generation with or without hydrogen storage, particularly in isolated sites, whose aim is to ensure power supply without interruption and minimize the environmental hazard, represents a viable and sustainable solution. It is in this context that this work was undertaken, it relates to the study and the dimensioning of a hybrid autonomou...

Fuels based on renewable energy sources (RES) are considered as an important mean to cope with environmental problems in transport. The core objective of this paper is to investigate the perspectives of “renewable fuels” from economic, energetic and ecological points-of-view in a dynamic framework till 2050. Renewable fuels are various 1 and 2 generation biofuels as well as electricity and hydr...
