Design and development of mixed metal oxides for high temperature thermochemical energy storage in active thermal barrier coating applications
Portilla Nieto, Yasmina (2022-10-17)This thesis proposes the design and development of novel mixed metal oxides as thermochemical material for application in thermal energy storage and especially as active thermal barrier coating. The development of this ... -
Effect of atomic substitution on the sodium manganese ferrite thermochemical cycle for hydrogen production
Torre, Francesco; Aguilar Sánchez, Teresa; Doppiu, Stefania; Oregui Bengoechea, Mikel; Arias Ergueta, Pedro Luis; Palomo del Barrio, Elena (Elsevier, 2022-10)This work presents the effect of atomic substitution on the MnFe2O4-Na2CO3 thermochemical cycle for H-2 production. The non-oxidative decarbonation/carbonation reaction of the MnFe2O4-Na2CO3 mixture is investigated as the ... -
Li4(OH)3Br-Based Shape Stabilized Composites for High-Temperature TES Applications: Selection of the Most Convenient Supporting Material
Mahroug, Imane; Doppiu, Stefania; Dauvergne, Jean-Luc; Serrano, Ángel; Palomo del Barrio, Elena (MDPI, 2021-05-13)Peritectic compound Li4(OH)3Br has been recently proposed as phase change material (PCM) for thermal energy storage (TES) applications at approx. 300 °C Compared to competitor PCM materials (e.g., sodium nitrate), the main ... -
NPG–TRIS Thermal Storage System. Quantification of the Limiting Processes: Sublimation and Water’s Adsorption
De La Pinta Alonso, Noelia; Santos Moreno, Sergio; Doppiu, Stefania; Igartua Aldamiz, Josu Mirena ; Palomo del Barrio, Elena; López, Gabriel Alejandro (MDPI, 2021-10-05)The NPG–TRIS binary system (NPG = (CH3)2C(CH2OH)2 = 2,2-dimetyl-1,3-propanodiol; TRIS = NH2C(CH2OH)3 = 2-Amino-2-(hydroxymethyl)-1,3-propanediol) was intensively investigated as a thermal energy storage system, due to the ... -
Sodium Manganese Ferrite Water Splitting Cycle: Unravelling the Effect of Solid–Liquid Interfaces in Molten Alkali Carbonates
Udaeta Gordón, Joseba; Oregui Bengoechea, Mikel; Torre, Francesco; Uranga, Nerea; Hernáiz, Marta; Lucio Castillero, Beatriz; Arias Ergueta, Pedro Luis; Palomo del Barrio, Elena; Doppiu, Stefania (ACS, 2024-06)In this work, the Na2CO3 of the sodium manganese ferrite thermochemical cycle was substituted by different eutectic or eutectoid alkali carbonate mixtures. Substituting Na2CO3 with the eutectoid (Li0.07Na0.93)2CO3 mixture ... -
Study of the Phase Transitions in the Binary System NPG-TRIS for Thermal Energy Storage Applications
Santos-Moreno, Sergio; Doppiu, Stefania; López, Gabriel Alejandro ; Marinova, Nevena; Serrano, Ángel; Silveira, Elena; Palomo del Barrio, Elena (MDPI, 2020-03-05)Neopentylglycol (NPG) and tris(hydroxymethyl)aminomethane (TRIS) are promising phase change materials (PCMs) for thermal energy storage (TES) applications. These molecules undergo reversible solid-solid phase transitions ...
