This research introduces a ‘Hydrogen Interconnector System’ (HIS) as novel method for transporting electrical energy over long distances. The system takes electricity from stranded renewable assets, converts it to hydrogen in an electrolyser plant, transports the demand centre via pipeline, where is reconverted either gas turbine or fuel cell plant. paper evaluates competitiveness of technology...

Abstract Green hydrogen produced from wind, solar or hydro power is a suitable electricity storage medium. Hydrogen typically employed as mid- to long-term energy storage, whereas batteries cover short-term storage. can be by any available electrolyser technology [alkaline electrolysis cell (AEC), polymer electrolyte membrane (PEM), anion exchange (AEM), solid oxide (SOEC)] if the fed renewable...

In Europe, electrification is considered a key option to obtain cleaner production of steel at the same time as electricity system portfolio expected consist an increasing share varying renewable (VRE) generation, mainly in form solar PV and wind power. We investigate cost-efficient designs hydrogen-based steelmaking systems dominated by VRE. develop apply linear cost-minimization model with ho...

The electrochemical conversion of excess CO2 into valuable chemicals, such as carbon monoxide (CO) and formic acid (HCOOH) offers the possibility combating climate change, while simultaneously providing sustainable raw materials for chemical industry. system design choice has large implications economic competitiveness processes. impact low-temperature electrolyser on potential CO HCOOH product...

The most recent investigations of operating conditions in a forward-bias bipolar-membrane zero-gap electrolyser using silver cathode catalyst for the reduction CO 2 to at low temperatures and near-ambient pressures are reported. First, performance was investigated as function feed humidification composition. highest partial current density 127 mA cm ?2 , which obtained an iR-corrected cell volt...

The aim of the work was to study effect electrolysis on process anaerobic digestion in example poultry manure with an inoculum activated sludge from a municipal wastewater treatment plant. set achieved by solving following tasks: microcopiing during under influence treatment; studying dynamics biogas yield and its component composition change pH values redox potential (ORP) experiments combinat...

Smart grids and smart microgrids (SMGs) require proper monitoring for their operation. To this end, measuring, data acquisition, storage, as well remote online visualization of real-time information, must be performed using suitable equipment. An experimental SMG is being deployed that combines photovoltaics the energy carrier hydrogen through interconnection photovoltaic panels, electrolyser, ...

Résumé This paper deals with multi-physics modelling of the stationary system. This modelling is the rst step to reach the fuel cell system dimensioning aim pursued. Besides this modelling approach based on the stationary energetic system, the novelty in this paper is both the new approach of the photovoltaic EMR modelling and the EMR of the hydrogen storage process. The granular modelling appr...

Increasing densities of (electrode–electrolyte-pore) triple phase boundaries (TPBs) / reaction sites enhance performances solid oxide electrochemical reactors (SOERs) in both fuel cell (SOFC) and electrolyser (SOE) modes. Inkjet 3D printing is capable construction ceramic microstructures on support layers, enabling fabrication SOERs with enhanced active area to geometric ratios, thereby up-scal...
