Conceptualizing novel CH₃OH-based thermochemical energy storage routes via a modeling approach

Thermal energy storage systems are an emerging option for efficient energy conversion and storage, especially if they can concentrate solar energy. This work studies a flexibleCH₃OH-to-CH₄ conversion system from intermediate conversion to synthesis gas. The design is based on a combination of proces...
