  • Energy and the Hydrogen Economy
    Energy and the Hydrogen Economy Ulf Bossel Fuel Cell Consultant Morgenacherstrasse 2F CH-5452 Oberrohrdorf / Switzerland +41-56-496-7292 and Baldur Eliasson ABB Switzerland Ltd. Corporate Research CH-5405 Baden-Dättwil / Switzerland Abstract Between production and use any commercial product is subject to the following processes: packaging, transportation, storage and transfer. The same is true for hydrogen in a “Hydrogen Economy”. Hydrogen has to be packaged by compression or liquefaction, it has to be transported by surface vehicles or pipelines, it has to be stored and transferred. Generated by electrolysis or chemistry, the fuel gas has to go through theses market procedures before it can be used by the customer, even if it is produced locally at filling stations. As there are no environmental or energetic advantages in producing hydrogen from natural gas or other hydrocarbons, we do not consider this option, although hydrogen can be chemically synthesized at relative low cost. In the past, hydrogen production and hydrogen use have been addressed by many, assuming that hydrogen gas is just another gaseous energy carrier and that it can be handled much like natural gas in today’s energy economy. With this study we present an analysis of the energy required to operate a pure hydrogen economy. High-grade electricity from renewable or nuclear sources is needed not only to generate hydrogen, but also for all other essential steps of a hydrogen economy. But because of the molecular structure of hydrogen, a hydrogen infrastructure is much more energy-intensive than a natural gas economy. In this study, the energy consumed by each stage is related to the energy content (higher heating value HHV) of the delivered hydrogen itself.

  • Hydrogen from Biomass Gasification

All rights Reserved ISBN, 978-1-910154-59-5 Published by IEA Bioenergy IEA Bioenergy, also known as the Technology Collaboration Programme (TCP) for a Programme of Research, Development and Demonstration on Bioenergy, functions within a Framework created by the International Energy Agency (IEA). Views, findings and publications of IEA Bioenergy do not necessarily represent the views or policies of the IEA Secretariat or of its individual Member countries. Executive Summary Hydrogen will be an important renewable secondary energy carrier for the future. Today, hydrogen is predominantly produced from fossil fuels. Hydrogen production from biomass via gasification can be an auspicious alternative for future decarbonized applications, which are based on renewable and carbon-dioxide-neutral produced hydrogen. This study gives an overview of possible ways to produce hydrogen via biomass gasification. First, an overview of the current market situation is given. Then, hydrogen production based on biomass gasification is explained. Two different hydrogen production routes, based on biomass gasification, were investigated in more detail. Hydrogen production was investigated for steam gasification and sorption enhanced reforming. Both routes assessed, appear suitable for hydrogen production. Biomass to hydrogen efficiencies (LHV based) of up to 69% are achieved and a techno-economic study shows, hydrogen selling prices of down to 2.7 EUR·kg-1 (or 79 EUR·MWh-1). Overall it can be stated, that governmental support and subsidies are necessary for successful implementation of hydrogen production based on biomass gasification technologies.

Approximately 10-11 million metric tonnes of hydrogen are produced in the US each year, enough to power 20-30 million cars or 5-8 million homes.1 Major current uses of the commercially produced hydrogen include oil refining (hydro-treating crude oil as part of the refining process to improve the hydrogen to carbon ratio of the fuel), food production (e.g., hydrogenation), treating metals, and producing ammonia for fertilizer and other industrial uses.

  • Options for Producing Low-Carbon Hydrogen at Scale
    Options for producing low-carbon hydrogen at scale POLICY BRIEFING POLICY BRIEFING Politics and science frequently move on vastly different timescales. A policymaker seeking evidence on a new policy will often need the answer in weeks or months, while it takes years to design and undertake the research to rigorously address a new policy question. The value of an extended investigation into a topic cannot be understated, but when this is not possible good evidence is better than none. The Royal Society’s series of policy briefings is a new mechanism aiming to bridge that divide. Drawing on the expertise of Fellows of the Royal Society and the wider scientific community, these policy briefings provide rapid and authoritative syntheses of current evidence. These briefings lay out the current state of knowledge and the questions that remain to be answered around a policy question often defined alongside a partner.

  • Thermochemical Water Splitting Cycles
    Thermochemical water splitting cycles Two processes to effect splitting of the water molecule by means of an external heat source are competing for adoption, for the long-term production of hydrogen: high-temperature electrolysis, and splitting the water molecule through a succession of chemical reactions: a thermochemical cycle. Both processes form part of a strategy of voluntary reduction of greenhouse-gas emissions, and of alternatives to ever-scarcer fossil resources, and thus do not involve hydrocarbons. ince hydrogen is only an energy carrier, not a Sprimary energy source,some such source must be available if hydrogen is to be generated. Aside from hydrocarbons,only nuclear energy currently has the capability to supply such energy, for the mass produc- tion of hydrogen.Hydrogen demand should experience strong growth in coming years.At present, and for the short term, hydrogen is mainly used in the chemical and oil industries,in particular to produce lighter frac- tions from heavy hydrocarbons. If, in the decades to come, hydrogen were to be used in transportation, the energy landscape would undergo an upheaval. To take an example: if in France hydrogen were to substitute wholly for gasoline in transportation,and if that hydro- gen were to be generated by means of nuclear power stations,the current fleet of such power stations would have to be increased practically fourfold! Which shows how important the stakes are, and the need to subject these two paths to detailed investigation, in order to be in a position to make the right choices, when the time arrives. It should be noted that this research is a long-term effort,and that,for several decades yet,hydro- Stroppa/CEA gen will be produced, in the main, by methane refor- P.

Abstract: Global energy sources are being transformed from hydrocarbon-based energy sources to renewable and carbon-free energy sources such as wind, solar and hydrogen. The biggest challenge with hydrogen as a renewable energy carrier is the storage and delivery system’s complexity. There- fore, other media such as ammonia for indirect storage are now being considered. Research has shown that at reasonable pressures, ammonia is easily contained as a liquid. In this form, energy density is approximately half of that of gasoline and ten times more than batteries. Ammonia can provide effective storage of renewable energy through its existing storage and distribution network.
