An apparatus and method for storing and transporting hydrogen by employing carbon dioxide as a storage medium. An electrolyzer (20) uses energy from renewable sources (15) to provide hydrogen by dissociating water. A reactor (40) forms a product by reacting hydrogen and carbon dioxide (70). The product (50) is transported to a consumption location (80) or the storage location (85). A storage device (87) may be employed to store retained carbon dioxide (67) produced when the product is consumed. Retained carbon dioxide is transported to the reactor location (40) to be reacted with the hydrogen provided from a hydrogen source. (FIG. – 8b)
