The Isaac Peral (S-80 Plus) class is a Spanish class of submarines being built by the state-owned Spanish company Navantia at its Cartagena (Murcia) shipyard.

The class has its roots in the late 1990s, and Spain ordered the submarines into production in 2003. Due to problems with the design, it had to be extensively redesigned in the 2010s, and a Spanish government budget crisis forced additional delays. On November 30, 2023, the first submarine of the class entered service with the Spanish Navy.

The S-80's air-independent propulsion (AIP) system is based on a bioethanol-processor consisting of a reaction chamber and several intermediate Coprox reactors. Provided by Hynergreen from Abengoa, the system transforms the bioethanol (BioEtOH) into high purity hydrogen. The output feeds a series of fuel cells from UTC Power company.

The reformator is fed with bioethanol as fuel and oxygen (stored as a liquid in a high pressure cryogenic tank), generating hydrogen and carbon dioxide as subproducts. The produced hydrogen and more oxygen is fed to the fuel cells.

The first two boats will enter service without the AIP - it will be added during the first scheduled overhaul (7 years after delivery to the Spanish Navy). The third and fourth boat will receive the AIP unit during construction.
