Description du projet
Une approche durable, en une seule étape, de production de gaz de synthèse
Le gaz de synthèse, un produit intermédiaire essentiel dans l’industrie chimique, est un mélange d’hydrogène et de monoxyde de carbone. Le projet SOMMER, financé par l’UE, se propose de développer une voie neutre en carbone de production de gaz de synthèse en intégrant l’énergie solaire dans un réacteur catalytique à membrane pour séparer l’eau et le CO2. Cette approche innovante supprimera le besoin d’énergie fossile pour produire le gaz de synthèse et remplacera le gaz naturel par du CO2 comme matière première. La technologie proposée combinera un processus en une seule étape de conversion thermochimique du CO2 et de l’H2O avec des catalyseurs hautement sélectifs, une membrane composite à double phase et une centrale thermique solaire concentrée. Le concept permettra un fonctionnement adaptable en alternant deux modes: une approche solaire à 1 500 °C et une approche basée sur le biogaz à 900 °C.
Objectif
SOMMER will develop and demonstrate a novel carbon-neutral pathway for syngas production by integrating solar energy directly into a catalytic membrane reactor for the splitting of H2O and CO2 (e.g. captured from high carbon emitting industries or by direct air capture). This will allow SOMMER to overcome the fossil-based energy requirements for the production of syngas and to consume CO2 instead of natural gas as feedstock. Syngas, the mixture of H2 and CO, is a crucial intermediate product in the chemical industry. Thus, SOMMER will consider the entire value-chain from CO2 provision from a cement plant to syngas formation and further processing syngas to valuable and shippable products such as DME or methanol.
The core of the SOMMER technology lies in the optimized energy integration of an emerging single-step CO2 and H2O thermochemical conversion process supported by highly selective catalysts and a dual-phase composite membrane, and a concentrated solar-thermal plant to supply the thermal energy demand. The main outcomes of SOMMER involve the experimental demonstration and evaluation of the innovative solar-powered membrane technology, and the development of high performance and cost-effective membranes as key components, thereby bringing the technology to the next level. SOMMER will advance membrane manufacturing via slip-casting, as a more mature approach, and via additive manufacturing to optimize the effective membrane surface area in the reactor. The concept is expected to have the future advantage of prolonged and flexible operation by switching between two operational Cases: I) Purely solar approach at 1500 °C and II) a biogas-supported approach at 900 °C.
In addition, the identification of technological, ecological and economical potential for a flexible and highly efficient solar syngas production will contribute to the development of a detailed roadmap and provide the basis for the pre-commercialization through follow-up R&D development activities.
