About this Research Topic
To achieve the sustainability and the stability of the energy system, primary energy consumption slowly but steadily moves from fossil to renewable sources. A transition is therefore unavoidable from a unique and stock-based resource to a large variety of sources. Energy storage into energy carriers of all sorts becomes necessary; it includes power-to-fuel (such as hydrogen, ammonia, methane, methanol), new generation biofuels (XTL), waste-to-fuel technology and metal chemical looping.
These energy carriers span such a large range of physico-chemical properties that their characterization is key to enabling their pure or combined use. This Research Topic aims at contributing to a better characterization of these fuels and their reactivity, from a fundamental perspective in simplified reactors, to their performance in more realistic applications.
Contributions should answer one of these questions for any alternative energy carrier:
1. Through what mechanism does its conversion produce energy?
2. What are the pollutants or limitations in using these energy carriers?
3. What are the performances of energy carriers in more realistic applications?
Keywords: waste-to-fuel, energy carrier, biofuel, combustion, power-to-fuel
