As the global deployment of renewable technologies accelerate, finding efficient ways to store energy will aid in responding shifting demands. A prospective option not only harvesting solar but also emission‐free heating is MOlecular Solar Thermal (MOST) storage. central part MOST applications develop methods release stored energy. Herein, Quadricyclane (QC)‐to‐Norbornadiene catalyzed back reaction explored a specially designed packed‐bed reactor. Four distinctly sized and purposely synthesized platinum on activated carbon catalysts are studied trigger heat from energy‐dense QC isomer. The fully characterized using variety structural, surface, spectroscopic techniques. Parameters optimize catalytic conversion flow conditions including particle size packing behavior, rates, molecular residence times. Moreover, CO pulse chemisorption technique, site time yield values turnover number reported. Complementary reactions, computational fluid dynamic simulations applying lattice Boltzmann two packed beds different ranges done evaluate fluid‐dynamic behavior within reactor bed ascertain ideal density for catalysis applications.
