Abstract

Curtailment of renewable power, which results from the intermittency of renewable sources, is inevitable from an economic perspective, especially for islanded systems. This work explores the economic value of curtailed renewable power using methanol production with a dedicated renewable power system as a basis. A cascade design of methanol plants is proposed that the first plant is powered by renewable energy directly from renewable power generation, whereas the subsequent plants are powered using the curtailed energy from the previous plant. The size of the subsequent plants and energy storage units are optimised using a modelling approach. When the first and the second plant are compared, ..
