Potential of Aluminum as a Metal Fuel for Supporting EU Long‐Term Energy Storage Needs

Advanced Materials Technologies, Volume 9, Issue 15, August 7, 2024.
In this manuscript, Barelli et al. evaluates the long‐term energy storage (ES) needs associated to the EU's energy transition and proposes an innovative approach based on aluminum as a green energy carrier with high volumetric energy density. Abstract The EU's energy transition necessitates availability of green energy carriers with high volumetric ...

Oxide Scale Formation of Stainless Steels with Different Heating Methods – Effect of Hydrogen as Fuel

steel research international, Volume 95, Issue 1, January 2024.
Transition toward CO2‐free heating by replacing natural gas with H2 as the combustion gas, or by electrifying the reheating furnace, affects the oxide scale formation of stainless steels. The results indicate the potential reheating conditions to the use of H2 fuels with minor changes of oxide scale and the possibility to reduce oxidation by induction ...

Numerical models for the phenomenological study of flameless combustion

Ingeniería e Investigación, 2009
Flameless combustion is a technique which offers environmental advantages such as lower than 100 ppm NOx and CO emis- sions due to below 200 K temperature gradients. Flameless combustion also supplies higher than 70% energy efficiency.

Development of a Novel Cyclonic Flow Combustion Chamber for Achieving MILD/Flameless Combustion

Energy Procedia, 2015
burner. The main pre-heated flow rate composed by diluent and oxygen and the fuel (at environmental temperature) are fed inside the combustion chamber from one side. Diametrically opposed the feeding configuration is reproduced, thus realizing a cyclonic flow field inside the reactor. The outlet is located on the top of the chamber.
