Other Hydrogen Production Methods
Sustainable Hydrogen Production, 2016Co-Authors: Ibrahim Dincer, Calin ZamfirescuAbstract:In this chapter, a number of atypical Hydrogen production methods are discussed in this chapter based on a literature survey of past publications. The focus of the chapter is on older or relatively known methods. Some of these older methods may be interest in newer Green Hydrogen production applications. The following hybrid thermochemical water splitting methods are discussed: photo-thermochemical, photo-electro-thermochemical, radio-thermochemical. Two methods applicable to Hydrogen production from fossil fuels using process/waste heat generated by nuclear reactor are discussed, namely coal hydrogasification and nuclear-based natural gas reforming. Also, solar thermochemical reformation of fuels to generate Hydrogen is introduced. Past studies demonstrated an electrolysis method conducted in molten alkali rather than in alkaline solution. This process can be conducted at temperature over 250°C which brings thermodynamic benefits toward better efficiency. This process is also reviewed and discussed based on some critical literature information. Finally, the chapter ends with a section on Green Hydrogen from ammonia in which clean ammonia synthesis, ammonia distribution and storage and Hydrogen generation from ammonia are taught.

Chapter 4 – Hydrogen Production by Thermal Energy
Sustainable Hydrogen Production, 2016Co-Authors: Ibrahim Dincer, Calin ZamfirescuAbstract:In this chapter, thermal (primarily heat) energy-driven Hydrogen production methods are classified, discussed and evaluated with a focus on Green-Hydrogen generation. It begins with a section on thermochemical-Hydrogen production fundamentals, with a review of the thermodynamic analyses of thermochemical reactions and equilibrium calculations through Gibbs free energy minimization. The efficiency formulations for the performance assessments of thermochemical-Hydrogen production systems are proposed through energy and exergy approaches. The thermochemical-Hydrogen production methods are thereafter introduced in sequence, starting with water thermolysis, pure thermochemical water-splitting cycles, hybrid cycles and gasification for Green-Hydrogen production. Furthermore, various integrated systems for Hydrogen production using nuclear, solar-thermal, biomass-based and clean-coal process Hydrogen production are introduced and discussed with some case studies.

Green methods for Hydrogen production
International Journal of Hydrogen Energy, 2012Co-Authors: Ibrahim DincerAbstract:This paper discusses environmentally benign and sustainable, as Green, methods for Hydrogen production and categorizes them based on the driving sources and applications. Some potential sources are electrical, thermal, biochemical, photonic, electro-thermal, photo-thermal, photo-electric, photo-biochemical, and thermal-biochemical. Such forms of energy can be derived from renewable sources, nuclear energy and from energy recovery processes for Hydrogen production purposes. These processes are analyzed and assessed for comparison purposes. Various case studies are presented to highlight the importance of Green Hydrogen production methods and systems for practical applications. © 2011, Hydrogen Energy Publications, LLC.

Design for On-Site Hydrogen Production for Hydrogen Fuel Cell Vehicle Refueling Station at University of Birmingham, U.K.
Energy Procedia, 2012Co-Authors: Daniel Symes, Alex Shields, Aman Dhir, Waldemar Bujalski, Ben Green, Bushra Al-duri, Matt LeesAbstract:Abstract In April 2008, the University of Birmingham launched the first permanent Hydrogen Refuelling Station in the UK. This enabled the refuelling of the only at the time fleet of Hydrogen Hybrid Fuel Cell Vehicles (HHFCV) in the UK. To maintain the low emissions ethos, the ultra-high purity “Green” Hydrogen for the refuelling station was supplied off site, from a third party contractor. The University aims to be the first campus in the UK that is carbon neutral and this project scopes to produce “Green” Hydrogen on-site to power the fleet of HHFCVs. Electrolysis is currently the only commercial method for producing ultra-high purity Hydrogen without the need for, what could prove to be very costly, additional purification steps. Working in collaboration with ITM Power, a HPac Model electrolyser has been installed to produce electrolytic Hydrogen on-site (up to 1.25 kgH2/day). The HPac uses PEM technology, which eliminates the need for hazardous alkaline substances, to produce Hydrogen. The input requirements are ASTM Type 2 de-ionised (DI), water and 240 V power supply. Hydrogen is produced at pressures up to 15 bar [1]. However, there is a need to incorporate this unit within the existing Hydrogen infrastructure incorporating 350 bar Air Product refuelling station. An integrated delivery system has been designed and initial results are presented herein.

modelling and control of Hydrogen and energy flows in a network of Green Hydrogen refuelling stations powered by mixed renewable energy systems
International Journal of Hydrogen Energy, 2012Co-Authors: Hanane Dagdougui, Ahmed Ouammi, Roberto SacileAbstract:Abstract The planning of a Hydrogen infrastructure with production facilities, distribution chains, and refuelling stations is a hard task. Difficulties may rise essentially in the choice of the optimal configurations. An innovative design of Hydrogen network has been proposed in this paper. It consists of a network of Green Hydrogen refuelling stations (GHRSs) and several production nodes. The proposed model has been formulated as a mathematical programming, where the main decisions are the selection of GHRSs that are powered by the production nodes based on distance and population density criteria, as well the energy and Hydrogen flows exchanged among the system components from the production nodes to the demand points. The approaches and methodologies developed can be taken as a support to decision makers, stakeholders and local authorities in the implementation of new Hydrogen infrastructures. Optimal configurations have been reported taking into account the presence of an additional Hydrogen industrial market demand and a connection with the electrical network. The main challenge that has been treated within the paper is the technical feasibility of the Hydrogen supply chain, that is mainly driven by uncertain, but clean solar and wind energy resources. Using a Northern Italian case study, the clean Hydrogen produced can be technically considered feasible to supply a network of Hydrogen refuelling stations. Results show that the demands are satisfied for each time period and for the market penetration scenarios adopted.

2011 IEEE International Systems Conference, 2011Co-Authors: Hanane Dagdougui, Ahmed Ouammi, Roberto SacileAbstract:In this paper, an optimization model of Green Hydrogen Refuelling Station (GHRS) is presented. The GHRS is powered completely by a wind farm to satisfy predefined Hydrogen fuel and electrical energy demands. The model based on a mathematical programming is developed to control both energy and Hydrogen flows exchanged among the system components. The optimization model has been applied on one week basis to a case study in the province of Savona, Italy. Optimal results are reported taking into account the presence of an additional Hydrogen industrial market and a connection with the electrical network.

thermodynamic feasibility analysis of a water splitting thermochemical cycle based on sodium carbonate decomposition
International Journal of Hydrogen Energy, 2019Co-Authors: Fernando Olmos, Brian P Hennessy, Ioannis V Manousiouthakis, Ibubeleye Somiari, Vasilios I ManousiouthakisAbstract:Abstract A novel water-splitting thermochemical cycle for the production of Green Hydrogen is introduced. This three-step cycle is based on the thermal decomposition of sodium carbonate. In this work, thermodynamic equilibrium analysis of the cycle's constituent reactions is performed, for a variety of temperatures, pressures, and dilution ratios. Feasible temperature/pressure/dilution operating windows are identified for the cycle's reactions such that the maximum temperature of the cycle can be generated using current concentrated solar power (CSP) technologies, thus enabling the replacement of steam methane reforming (SMR) as the major industrial production method of Hydrogen.
