Electrochemical

The liquid is a suspension of nano-molecules, each of which acts like a little battery. In sufficient concentrations, the team says that the liquid can store very large amounts of energy, which can be released as electricity or hydrogen gas.

The DSS and GSS platforms integrates the battery, power conversion, and controls technology together. The system is pre-engineered to simplify design, installation, commissioning, operation, and maintainence.

Flow battery stores electricity as chemical energy in two large tanks.

It is a combination of lead acid and ultracapacitor

The technology is to mix powder with a liquid electrolyte

Glass-Protected lithium battery, protected lithium electrode, lithium air, lithium water, and lithium sulfur

A hybrid redox flow battery. As part of the ARPA-E (DAYS) program, the Primus Power team will work with the Columbia Electrochemical Energy Center to develop a long-duration grid energy storage solution by using a new approach to the zinc bromine battery, a popular chemistry for flow batteries. Taking advantage of the way zinc and bromine behave in the cell, the battery will eliminate the need for a separator to keep the reactants apart when charged, as well as allow all the electrolyte to be stored in a single tank, instead of multiple cells. This reduction in “balance of plant” hardware will reduce system cost.

Flow battery converts chemical energy into electricity by pumping electrolytes through a stack od electrochemical cells.

Aqueous Hybrid Ion is built from components that are made using abundant nontoxic materials the environment both in manufacturing process and energy storage.
