Electrochemical generation of hydrogen by non-precious metal electrocatalysts at a lower overpotential is a focus area of research directed towards sustainable energy. The exorbitant costs associated with Pt-based catalysts is the major bottleneck associated with commercial-scale hydrogen generation. Strategies for the synthesis of cost-effective and stable catalysts are thus key for a prospect...

In December 2019, the European Commission unveiled an ambitious project, Green Deal, which aims to lead Union climate neutrality by 2050. This is a significant challenge for all EU countries, and especially Poland. The role of hydrogen in processes decarbonization economy transport being discussed many countries around world find rational solutions this difficult complex problem. There ongoing ...

We examine a different approach to complete the decarbonization of Russian economy in world where climate policy increasingly requires radical reduction emissions wherever possible. propose an energy system that can supply solar and wind-generated electricity fulfill demand which accounts for intermittency problems. This is instead common planning expensive carbon capture storage, massive incre...

Abstract The hydrogen economy has been a major vision for many futurists, over half century, as way to transition world not dependent on fossil fuels (Bockris, Science 176:1323, 1972). As with views, the complete perspective from which all potential change can be viewed. It therefore passionate if somewhat fundamentalist following. This paper outlines how electrification now superseded much of ...

Abstract With increasing global interest in molecular hydrogen to replace fossil fuels, more attention is being paid potential leakages of into the atmosphere and its environmental consequences. Hydrogen not directly a greenhouse gas, but chemical reactions change abundances gases methane, ozone, stratospheric water vapor, as well aerosols. Here, we use model ensemble five atmospheric chemistry...

This article identifies and discusses the scientific challenges of hydrogen storage in porous media for safe efficient large-scale energy to enable a global economy.

In article number 2010483, Lars Bannenberg, Herman Schreuders, and Bernard Dam develop materials to optically sense hydrogen. These can be used in versatile hydrogen sensors, being essential for the implementation of a green economy. Using nanoconfinement effects alloying, they rationally design thin film optical sensing material with exceptional characteristics, including range seven orders ma...

Under the rapid development of sharing economy, performance is important for the prosperity of this innovative commercial model. However, the performance in sharing economy is less discussed in the academic field. Revenue and occupancy rate are widely applied as two ideal measures of performance in hospitality market. This study tries to fill the research gaps with both two measurements. Based ...

The only remaining controversy in Taiwan’s efforts to standardize its pinyin system for Chinese is whether to adopt Tongyong or Hanyu; while the former has an intense symbolic value of indigenization, the latter enjoys a substantial globalized distribution. This paper first makes clear the nature of ‘interface’ of any pinyin system and examines this seemingly domestic issue from the perspective...
