The Future of Hydrogen
In the presented work, we performed an integrated techno-environmental assessment of hydrogen production from woody biomass gasification, combined with CO 2 capture and storage CCS. We have included three different types of gasification technologies for syngas production. CO 2 is captured from the syngas with conventional amine-based technology. Based on our integrated approach linking detailed process simulation with Life Cycle Assessment, we are able to quantify benefits and potential trade-offs of a wide range of process configurations from both technical and environmental perspectives in a consistent way. We have also performed a comparative evaluation of hydrogen use in fuel cell electric vehicles passenger cars and freight trucks , to investigate the role of hydrogen in decarbonizing the transport sector.
At the request of the government of Japan under its G20 presidency, the International Energy Agency produced this landmark report to analyse the current state of play for hydrogen and to offer guidance on its future development. The report finds that clean hydrogen is currently enjoying unprecedented political and business momentum, with the number of policies and projects around the world expanding rapidly. It concludes that now is the time to scale up technologies and bring down costs to allow hydrogen to become widely used. The pragmatic and actionable recommendations to governments and industry that are provided will make it possible to take full advantage of this increasing momentum. Hydrogen and energy have a long shared history — powering the first internal combustion engines over years ago to becoming an integral part of the modern refining industry.
Hydrogen production from sustainable resources for the generation of pure and low cost hydrogen is described in the chapter. Several potential hydrogen production techniques are introduced and analyzed. The challenges and the advantages of each production method will be discussed. Furthermore, the chapter will introduce hydrogen infrastructure development for mobility applications and will discuss hydrogen storage challenges. Hydrogen production for fuel cell technologies requires an improvement regarding sustainability of the hydrogen supply and an improvement regarding decentralized hydrogen production.

In any future hydrogen-based economy, key economic determinants will be the cost and safety of the fuel distribution system from the site of manufacture of the hydrogen to the end user. This is true of any fuel, but hydrogen presents unique challenges because of its high diffusivity, its extremely low density as a gas and liquid, and its broad flammability range relative to hydrocarbons and low-molecular-weight alcohols. These unique properties present special cost and safety obstacles at every step of distribution, from manufacture to, ultimately, on-board vehicle storage. Also critical is the form of hydrogen being shipped and stored. Hydrogen can be transported as a pressurized gas or a cryogenic liquid; it can be combined in an absorbing metallic alloy matrix or adsorbed on or in a substrate or transported in a chemical precursor form such as lithium, sodium metal, or chemical hydrides.

Hydrogen is used extensively for its chemical properties, and on a global basis most hydrogen is produced from fossil fuels. As shown in Chapter 5 , the committee believes that a transition to a hydrogen energy system would likely rely on hydrogen H 2 from the reforming of natural gas and from electrolysis powered by a grid mix inclusive of coal-fired power plants. The fossil resources combusted or used as feedstock during such a transition will produce by-product carbon dioxide CO 2.

Hydrogen not only needs to be produced, but it also needs to be transported and stored in the place of consumption. Such activities are particularly difficult due to the characteristics of hydrogen.
