Current status of water electrolysis for energy storage

1. Introduction. Power-to-Gas (PtG) and Power-to-Liquids (PtL) are often discussed as important elements in a future renewable energy system (. , , ).The conversion of electricity via water electrolysis and optionally subsequent synthesis together with CO or CO 2 into a gaseous or liquid energy carrier enables a coupling of the electricity, chemical, mobility and heating sectors.

Hydrogen, in principle still lighter, ignites very easily Boron: A Better Energy Carrier than Hydrogen? while with boron the easy part is the handling. If drivers send slabs of (even less ignitable!) boria across the Earth, and get back boron, both forms'' manageability helps this energy tap be efficient.

Reaction rate - Wikipedia

2018-12-29For a chemical reaction a A + b B → p P + q Q, the rate equation or rate law is a mathematical expression used in chemical kinetics to link the rate of a reaction to the concentration of each reactant. It is often of the type: = [] [] For gas phase reaction the rate is often alternatively expressed by partial pressures.. In these equations k(T) is the reaction rate coefficient or rate
