In the realm of traditional energy storage technologies, a diverse array of methods has been employed to capture and utilize energy efficiently. From the ubiquitous lithium-ion batteries to the innovative pumped hydro storage systems, each approach offers unique advantages and challenges. In this segment, we explore the workings of these traditional technologies, their applications, and their contributions to the evolving landscape of energy storage.

Battery Technology

Lithium-ion batteries stand as the undisputed champions in the realm of portable energy storage. Their dominance in the market can be attributed to their high energy density, relatively low self-discharge rate, and lightweight design. At the heart of a lithium-ion battery lies a complex interplay of chemical reactions that facilitate the storage and release of electrical energy.

In simplified terms, a lithium-ion battery consists of three primary components: a cathode, an anode, and an electrolyte. During charging, lithium ions migrate from the cathode to the anode through the electrolyte, where they become embedded within the anode material. This process is reversed during discharge, as the lithium ions move back to the cathode, releasing electrical energy in the process.

Hydrogen Fuel Cells

Hydrogen fuel cells offer an alternative approach to energy storage, utilizing hydrogen gas as a fuel source to generate electricity through electrochemical reactions. At its core, a hydrogen fuel cell comprises an anode, a cathode, and an electrolyte membrane. Hydrogen gas is supplied to the anode, where it undergoes oxidation, releasing electrons that flow through an external circuit to produce electrical energy. Meanwhile, oxygen from the air reacts with electrons and protons at the cathode, forming water as a byproduct.

Despite their promise, hydrogen fuel cells face several limitations, including high production costs, limited infrastructure, and challenges associated with hydrogen storage and distribution. Current applications primarily focus on niche markets such as stationary power generation and transportation, with ongoing efforts to overcome technical and economic barriers.
