Lithium-ion batteries: Rechargeable batteries noted for their efficiency, energy density and long life compared to alternatives. Lithium-ion units have established themselves as the premier model of battery for both stationary and mobile energy storage.

Lithium iron phosphate (LFP): The cheapest type of lithium battery, which avoid using the critical minerals nickel and cobalt. While offering lower range and energy density than lithium-ion equivalents, recent improvements have seen the model set to account for 39% of batteries used in EVs this year.

Sodium-ion batteries: Rechargeable batteries which use sodium instead of lithium. While less energy dense than lithium-ion counterparts, sodium-ion chemistries are more readily obtainable, making them attractive due to shortages in critical minerals.

Solid-state batteries: These are early-stage batteries which have a different structure to conventional storage units. Instead of a liquid electrolyte, solid-state batteries use a solid electrolyte. While possessing greater energy density and a longer life span than alternatives, solid-state batteries are yet to demonstrate commercial viability and scalability.

Critical minerals: Raw materials essential to the energy transition. They include lithium, cobalt, copper and nickel, among others.

Energy aggregator: An an organisation that creates competition in the energy market, by grouping customers together to secure better terms. This grants brokers within the market greater leverage when negotiating tariffs and provides access to better rates.

Front-of-meter: Energy assets directly connected to the utility grid or are owned and operated by utility companies.

Behind-the-meter: Energy-related assets connected directly to the consumer's electrical network. These assets are typically located within or close to the consumer's premises.

Land bank: Land available for a developer to use for future projects.

Offtakers: In project finance, buyers who contractually agree to purchase all or a substantial share of future production from the project.
