AquaBattery develops eco-friendly, cost-effectively scalable, and safe electrical energy storage technologies. Their flagship products are the BlueBattery and GreenBattery, which can store excess renewable energy in saltwater.
In short, AquaBattery has the following technologies to offer.
BlueBattery: storage of electricity in concentration gradients of fresh and saltwater. GreenBattery: storage of electricity in concentration and pH gradients.
TerraBattery: storage of electricity in nickel-iron cells with an expected service life of 20+ years. At the end of life, this battery is fully recycled.
The problem we are solving
AquaBattery provides eco-friendly, cost-effectively scalable, and safe energy storage technologies to help accelerate the energy transition to 100% renewable energy without the need of significantly upgrading the PowerGrid connections.
Customers can increase their self-consumption of renewable energy that they generate locally without being limited by the grid connection. They can, for instance, choose to pay less by opting for a lower capacity grid connection. The excess energy obtained during peak production periods (e.g. from solar PV), that cannot be readily supplied to the grid as a result of the limitation, can be stored and delivered to the grid when the grid connections allow it i.e. during the night. AquaBattery endorses local generation and consumption of renewable energy. Thus, the key problems that we are addressing are: (1) help customers install more renewable energy generation capacity (e.g. putting more solar panels) without being limited by the PowerGrid and (2) increase self-consumption of renewable energy.
What is unique about our flagship products is that it can store renewable energy that is required to bridge a period with low solar and wind energy output (i.e. the Dunkelflaute) in a cost-effective manner. Namely, we can increase the storage capacity independently from the power unit. Dunkelflaute last typically 12 days and conventional batteries technologies such as those based on lead acid and lithium would become unaffordable at this scale and also unsafe.
