Which outcome limits sustained thermochemical energy storage density?

💡 Explanation

Sustained thermochemical energy storage is limited by accelerated catalyst deactivation, because the slow buildup of byproducts poisons the catalytic surface. Therefore catalytic activity falls, rather than maintaining high conversion rates or a favorable energy balance.
