Hydrogen storage: Materials, methods and perspectives
TL;DR: In this article, a review focusing on various hydrogen producing and storing methods that can be employed for creating a hydrogen economy is presented, where the latest advancements that have been made on different hydrogen storing materials and hydrogen storing technologies which have proven useful both on gravimetric and volumetric basis, have been highlighted.
A Lifecycle Emissions Model (LEM): Lifecycle Emissions from Transportation Fuels, Motor Vehicles, Transportation Modes, Electricity Use, Heating and Cooking Fuels, and Materials
TL;DR: In this paper, a recently revised version of the greenhouse-gas emissions model was presented, called the Lifecycle Emissions Model (LEM), which calculates energy use, air-pollutant emissions, and CO2-equivalent emissions of carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), chlorofluorocarbons (CFC-12), nitrogen oxides (NOx), carbon monoxide (CO), non-methane organic compounds (NMOCs) weighted by their ozone-forming potential, sulfur
