Descripción del proyecto
Óxido de grafeno reducido: una fuente de energía eléctrica asequible, ecológica y a demanda
La generación de electricidad a partir de fuentes renovables resulta impredecible, pero el hidrógeno (H2) ofrece una vía prometedora para el almacenamiento de energía. Dado que aproximadamente el 95 % del H2 procede de la ruptura del enlace carbono-hidrógeno (C-H) de los hidrocarburos, el almacenamiento de hidrógeno unido a carbono podría ofrecer una solución a largo plazo. Sin embargo, la extracción de hidrógeno de los hidrocarburos líquidos requiere la emisión de CO2. Para hacer frente a este problema, el proyecto financiado con fondos europeos LESGO busca almacenar energía en el enlace C-H del óxido de grafeno reducido (rGO-H). Entre las ventajas del rGO-H se incluye un almacenamiento seguro, un transporte sencillo, una densidad energética más de cien veces mayor que la del gas de H2 y la ausencia de emisiones de CO2 durante el proceso de generación de electricidad. El proyecto promoverá una forma respetuosa con el medio ambiente y asequible de suministrar energía a demanda allí donde sea requerida.
Objetivo
Hydrogen is being pursued as a promising route to store energy, potentially mitigating the unpredictability of electricity generation based on renewables. Provided that more than 95% of H2 produced comes from breaking the C-H bond in hydrocarbons, it is natural to think that storing H bound to C may provide a long-term solution to this challenge. However, liquid hydrocarbons are not an optimal solution given that the process of extracting H from them involves CO2 emissions. LESGO proposes to store energy in the C-H bond of reduced graphene oxide (rGO-H). rGO-H can be stored safely, exhibits an energy density more than 100 times larger than that of H2 gas, and can be easily transported wherever the electricity generation is needed. LESGO will demonstrate that rGO-H can become an ideal energy stock at an affordable cost and used to supply electrical power on demand where it is required. In the complete cycle from sun light to electrical power the raw material for storage evolves from graphite back to graphite with no CO2 emissions in any intermediate step. LESGO’s consortium has been structured to bring together a highly interdisciplinary community that will enable the emergence of an ecosystem around a circular economy relying on the use of: widely available raw materials, storing energy in chemical bonds, using it in applications that require electrical power, and finally recovering the materials for a second or multiple lives. Industrial (GRAPHENEA, HST, GENCELL and CRF), academic (UDE and AALTO) or research center (IREC and ICFO) activities are completely interwoven throughout the entire implementation of LESGO. Within the duration of LESGO, CRF will develop an application in the transport sector where rGO-H will be tested as the fuel in a support battery providing a fast charging for current electric vehicles. When looking ahead beyond the consortium, DBT will foster the engagement of a wider stakeholder/public community to consolidate the ecosystem around rGO-H.
