A PHEV (plug-in hybrid electric vehicle) is a hybrid electric vehicle whose battery can be recharged by plugging a charging cable into an external electric power source, and also internally by its on-board internal combustion engine-powered generator. Most PHEVs are passenger cars, but there are also PHEV versions of commercial vehicles and vans, utility trucks, buses, trains, motorcycles, mopeds, and even military vehicles.

Phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. The three principal phosphate producer countries are China, Morocco and the United States which account for about 70% of world production. Phosphate is a component of lithium iron phosphate batteries. This battery chemistry is often used in power tools, electric vehicles, solar energy installations and more recently large grid-scale energy storage.

Pink hydrogen is generated through electrolysis powered by nuclear energy. Nuclear-produced hydrogen can also be referred to as purple hydrogen or red hydrogen. In addition, the very high temperatures from nuclear reactors could be used in other hydrogen productions by producing steam for more efficient electrolysis or fossil gas-based steam methane reforming.

A Power Purchase Agreement (PPA) often refers to a long-term electricity supply agreement between two parties, usually between a power producer and a customer (an electricity consumer or trader). The PPA defines the conditions of the agreement, such as the amount of electricity to be supplied, negotiated prices, accounting, and penalties for non-compliance.  A PPA is the principal agreement that defines the revenue and credit quality of a generating project and is thus a key instrument of project finance. There are many forms of PPA in use today and they vary according to the needs of buyer, seller, and financing counter parties.
