Hydrogen Storage Materials

by Darren P. Broom

The problem of storing hydrogen safely and effectively is one of the major technological barriers currently preventing the widespread adoption of hydrogen as an energy carrier and the subsequent transition to a so-called hydrogen economy. Practical issues with the storage of hydrogen in both gas and liquid form appear to make reversible solid state hydrogen storage the most promising potential solution. Hydrogen Storage Materials addresses the characterisation of the hydrogen storage properties of the materials that are currently being considered for this purpose. The background to the topic is introduced, along with the various types of materials that are currently under investigation, including nanostructured interstitial and complex hydrides, and porous materials, such as metal-organic frameworks and microporous organic polymers. The main features of Hydrogen Storage Materials include: an overview of the different types of hydrogen storage materials and the properties that are of interest for their practical use;descriptions of the gas sorption measurement methods used to determine these properties, and the complementary techniques that can be used to help corroborate hydrogen uptake data; andextensive coverage of the practical considerations for accurate hydrogen sorption measurement that drive both instrument design and the development of experimental methodology.Hydrogen Storage Materials provides an up-to-date overview of the topic for experienced researchers, while including enough introductory material to serve as a useful, practical introduction for newcomers to the field.

Hydrography and Navigation on the Congo River: A Century of Visual History

by Paul Van Pul

In a time without GPS and echosounder, European engineers and black labourers worked for decades to get a better understanding of the nautical intricacies of the Congo River. This is the first comprehensive story, in text and custom-made maps, of the, in flow, second largest river in the world. We follow the earliest explorers mapping the river, the expeditions to find an alternative access to the ocean and the first land and hydraulic surveys to improve navigation. The constant movement of shallows and islands keeps the guardians of the river constantly on their toes. Over the years, better technologies on all fronts improved safety, data collection and fairway maintenance. In conclusion, the author describes a proposal to develop a 21st container port that would rival any port facilities on the African west coast.

Hydrohumanities: Water Discourse and Environmental Futures

by Kim De Wolff, Rina C. Faletti and Ignacio López-Calvo

A free open access ebook is available upon publication. Learn more at www.luminosoa.org. Discourse about water and power in the modern era have largely focused on human power over water: who gets to own and control a limited resource that has incredible economic potential. As a result, discussion of water, even in the humanities, has traditionally focused on fresh water for human use. Today, climate extremes from drought to flooding are forcing humanities scholars to reimagine water discourse. This volume exemplifies how interdisciplinary cultural approaches can transform water conversations. The manuscript is organized into three emergent themes in water studies: agency of water, fluid identities, and cultural currencies. The first section deals with the properties of water and the ways in which water challenges human plans for control. The second section explores how water (or lack of it) shapes human collective and individual identities. The third engages notions of value and circulation to think about how water has been managed and employed for local, national, and international gains. Contributions come from preeminent as well as emerging voices across humanities fields including history, art history, philosophy, and science and technology studies. Part of a bigger goal for shaping the environmental humanities, the book broadens the concept of water to include not just water in oceans and rivers but also in pipes, ice floes, marshes, bottles, dams, and more. Each piece shows how humanities scholarship has world-changing potential to achieve more just water futures.
