“…However, such process is also linked to the generation of CO2 emission, which fades the concept of "green hydrogen production" [10]. Aside from that, safety issues related to the physical hydrogen storage by compression and cooling means are also focus of discussion because of the very high pressure level (up to 700 to 800 bar) or very low temperatures (-252 ºC) required [11][12][13][14][15].…”

The photocatalytic dehydrogenation of formic acid has recently emerged as an outstanding alternative to the traditional thermal catalysts widely applied in this reaction.The utilization of photocatalytic processes for the production of hydrogen is an appealing strategy that perfectly matches with the idea of green and sustainable future energy scenario. However, it sounds easier than it is, and great efforts have been needed to design and develop highly efficient photocatalysts for the production of hydrogen from formic acid. In this work, some of the most representative strategies adopted for this application are reviewed, by paying particular attention to those systems based on TiO2, CdS and C3N4.

“…Statistics of accidents with CNG (compressed natural gas) vehicles shows that more than 1/3 of a total number of tank ruptures in a ¦re is due to pressure relief device failure. Volume of storage tanks ranges from 20 to 140 l. The risk of hydrogen-powered vehicles is above the acceptable level of 10 −5 if the onboard storage tank has ¦re resistance rating below 47 min for example of London roads [1]. This accounts for nonzero probability of thermally activated pressure relief device (TPRD) failure.…”

The development of computational §uid dynamics (CFD) model to simulate blast wave and ¦reball dynamics after high-pressure hydrogen tank rupture in a ¦re is described. Parametric study is performed to de¦ne the e¨ect of submodels, numerical methods, and parameters on the convergence of the simulations and reproduction of experimental data. Experiments with initial pressure in hydrogen tank of 350 and 700 bar were used to validate the model. The e¨ect of hydrogen combustion and tank opening on the blast wave strength is assessed. The simulated cases include instantaneous tank opening and half tank opening.

“…Much has been written in recent years about the future of hydrogen as an alternative to fossil fuels [1][2][3][4][5][6][7][8][9][10] and the challenges that ensue concerning safety aspects involving hydrogen containment or storage. These safety aspects are also of great importance in the context of nuclear decommissioning operations where hydrogen issues arise due to the corrosion of nuclear waste [11][12][13][14].…”

“…The dynamic pressure of the cloud explosion was found to be of similar order to the overpressure and the explosion/flame region approximately 1.25 times the original width of the cloud. Dadashzadeh et al [2] have recently provided a risk assessment methodology for onboard hydrogen-powered vehicle storage. The fire risk is defined in terms of "cost of human life per vehicle fire, and annual fatality rate per vehicle".…”

Many studies have been devoted to understanding the consequence of ignition events that could occur as a result of using hydrogen as an alternative to fossil fuels or when hydrogen is present in large scale industrial or nuclear waste sites. Little attention has however, been given to the effect of explosion in small scale operations: this could involve service work with manual handling and manipulation of gas containing packages or vessels. The purpose of this study is to begin to address this knowledge gap and report the results of an experimental program carried out to simulate the effect of localised and weakly confined small volume hydrogen explosions on personal safety. Three aspects of personal injury consequences are considered; injury from shock loading to the head/brain, skin burns and acoustic/hearing damage. It is concluded from ignition and acoustic noise exposure experiments, carried with stoichiometric hydrogen /air mixtures, that injuries arising from shock loading or burns to the skin are less likely than hearing damage. It is suggested that further work should focus on the noise exposure and hearing damage effects of small scale explosions.
