Hydrogen technology adoption analysis in Africa using a Doughnut-PESTLE hydrogen model (DPHM)

Review of developments in portable hydrogen production using microreactor technology.

Numerical Analysis of Hydrogen Transport using a Hydrogen-Enhanced Localized Plasticity Mechanism

In this study, the hydrogen transport phenomenon was numerically evaluated by using hydrogen-enhanced localized plasticity (HELP) mechanisms. Two dominant governing equations, namely, the hydrogen transport model and the elasto-plastic model, were introduced. In addition, the implicitly formulated equations of the governing equations were implemented into ABAQUS UMAT user-defined subroutines. T...

Bohr Model of Hydrogen

The atomic theory of matter has a long history, in some ways all the way back to the ancient Greeks (Democritus ca. 400 BCE suggested that all things are composed of indivisible “atoms”). From what we can observe, atoms have certain properties and behaviors, which can be summarized as follows: Atoms are small, with diameters on the order of 0.1 nm. Atoms are stable, they do not spontaneously br...

Simulating Market Transformation Dynamics Using a Hybrid Energy Economy Model: a Look at the Adoption of Hydrogen Fuel Cell Vehicles

Policymakers committed to inducing technological change need information about the Likely effects of alternative policies, potential adoption rates of clean technologies, and costs to society in the long run. My goal was to use a "hybrid energy economy model (CIMS), which combines a degree of behavioural realism, technological explicitness, and economy-wide feedback capabilities, to develop pol...

Technology Transitions: identifying challenges for hydrogen vehicles

Automobile firms are now developing alternatives to internal combustion engines (ICE), including hydrogen fuel cells and ICE/electric hybrids. Adoption/diffusion dynamics for alternative powered vehicles are more complex than those typical of most new products, due to the enormous size and importance of the automobile industry, the size and impact of the vehicle fleet, the presence of scale and...
