Ethanol as a hydrogen carrier with a value-added co-product
Traditional liquid organic hydrogen carriers rely on return/re-charge of the carrier and financial subsidy. We show that ethanol, available at scale from fermentation, can be a revenue-positive hydrogen carrier, owing to the value of its potassium acetate co-product, itself an emerging fertilizer.
