Gravity energy storage (GES) is an innovative technology to store electricity as the potential energy of solid weights lifted against the Earth's gravity force. When surplus electricity is available, it is used to lift weights. [pdf]
Currently, the energy grid is changing to fit the increasing energy demands but also to support the rapid penetration of renewable energy sources. As a result, energy storage devices emerge to add buffer capacity. [pdf]
NamPower, Namibia's state-owned power utility, has signed a contract with a Chinese joint venture to build the first utility-scale battery energy storage system (BESS) in the country and the Southern African region. [pdf]
Clockwork mechanisms are intricate systems that rely on mechanical energy to perform their functions, typically found in devices such as watches, clocks, and music boxes. At the heart of these systems lies the mainspring, a coiled spring that stores energy when wound. [pdf]
Modern systems like kinetic energy recovery systems (KERS) can store up to 500 joules per crank – enough to power a smartphone for 15 minutes of talk time [4]. In remote steppes where electricity grids fear to tread, nomadic families use hand crank storage units with flywheel technology. [pdf]
Let’s cut to the chase: In December 2023, Windhoek made history by launching Namibia’s first grid-scale energy storage system. This 54MWh project in Erongo Region isn’t just a battery installation – it’s a game-changer for a country where 70% of electricity was imported pre-2023 [1]. [pdf]
Mechanical watches use mainsprings to store energy, which is released gradually to power the watch. New materials and technologies like the Co-Axial escapement and unbreakable mainsprings enhance energy efficiency and durability. [pdf]

That’s essentially what clockwork energy storage devices aim to achieve. As the global energy storage market surges toward $33 billion annually [1], these mechanical marvels are carving a niche in renewable energy systems by offering simplicity and reliability. Let’s unravel why this old-school. .
tricity. Using this principle, . Grid-connected energy storage is needed in three categories: short duration (less than 1 hour) to regulate frequency; long duration (8 to 16 hours) for shiftin avy high-velocity spinning wheels. To avoid energy losses, the wheels are kept in a frictionless vacuum. [pdf]
