Estudio de viabilidad de LOHC para transporte de H2

Abstract

El presente trabajo evalúa la viabilidad técnica y económica de transportar hidrógeno utilizando Portadores Orgánicos Líquidos de Hidrógeno (LOHC) a través de la infraestructura de oleoductos existente, como una solución para la economía del hidrógeno. Inicialmente, se realiza un análisis comparativo de tres sistemas LOHC principales: Tolueno / Metilciclohexano, Dibenciltolueno / Perhidrodibenciltolueno y N-etilcarbazol / Perhidro-N-etilcarbazol. El sistema NEC es descartado en una fase preliminar debido a que su forma deshidrogenada es sólida a temperatura ambiente, lo que impide su bombeo por tuberías convencionales sin modificaciones costosas. Mediante cálculos hidráulicos detallados, basados en las especificaciones reales del oleoducto, se simula el transporte de los pares TOL/MCH y DBT/H18-DBT. Los resultados demuestran que el sistema DBT/H18-DBT es técnicamente inviable para la infraestructura actual. Su elevada viscosidad, especialmente en su forma hidrogenada, genera pérdidas de carga por fricción que resultan en una presión requerida superior a la máxima admisible por la tubería y la capacidad de las bombas existentes. En contraste, el par TOL/MCH resulta ser técnicamente viable. Su baja viscosidad, comparable a la de los combustibles convencionales, permite su transporte dentro de los límites operativos del sistema. Finalmente, el estudio concluye con un análisis económico y logístico. Se determina que un ciclo completo de transporte puede entregar 198.181 kg de hidrógeno puro, con un coste energético de bombeo de 0,0082 € por kg de H2. Si bien la reutilización de infraestructuras es prometedora, se subraya que este coste representa solo una pequeña fracción del coste total de entrega. Las propiedades fisicoquímicas del LOHC, especialmente la viscosidad, son el factor crítico determinante para la viabilidad de su transporte por oleoducto.
