The green energy gap. Finding the future of storage.

Capture vs. Storage

The goal of green energy storage is to supplement and eventually replace the fossil fuel power grid. Despite rapid growth in capture technology, renewable sources like wind and solar are unpredictable. The future of a sustainable grid relies on innovative storage systems to close the gap.

7,856 TWh of green electricity captured in 2021.

In 2021, the world generated 7,856 TWh of electricity, up 22% from 2020. 22,500+ TWh is our global annual need.

Only 0.34 TWh of green electricity storage capacity in 2021.

In 2021, the rated power of global GESS was only 340 GWh (0.34 TWh). Only an additional 550 GWh is predicted to be operational by 2023.

Lithium-ion controls more than 90% of the global energy storage market.*

Advantages

Short-term efficiency: Peak efficiency at 90% – 95% up to 2,500 cycles (or 3 – 5 years)
Inexpensive: Manufacturing cost decreased 65% – 90% in the last decade
Easy to deploy: Compatibility with existing loads and grid applications

Disadvantages

Long-term inefficiency: After 5,000 cycles (or 10 years) efficiency drops to 70%
Safety: Unprotected circuits require regular monitoring to avoid battery fires
Environmental impact: Production plunders water reserves and pollutes soil

Current and future storage alternatives

By exploring alternatives to Lithium-ion, we can install more permanent, safe, and effective storage solutions to unlock the potential of Green Energy Storage Systems.

Alternative Batteries (BESS)

Alternative metal-ion batteries, such as Sodium, Potassium and Aluminium have shown potential to be more cost effective than Li-ion. Superior electrolyte exchange, conductivity, and current collectors make these viable alternatives to support existing battery storage infrastructure.

Compressed Air (CAES)

Ambient air or another gas is compressed and stored underground at high pressure. When energy is needed, the air or gas is super heated in an expansion turbine to drive electric generators.

Superconducting Magnets

Direct current is pushed through a superconducting coil that has been cryogenically cooled to below its critical superconducting temperature. The result is a magnetic field which stores electrical energy..

Pumped Hydroelectric

Two water reservoirs at different elevations generate power as water moves from one to the other by utilizing the downward momentum of gravity. The flow of the water turns electric turbines, but also requires some power to cycle water back to high elevation.

Flywheel (FESS)

Kinetic energy is stored by accelerating a rotational device at high speed and then drawing on its rotational energy to power generators with very little frictional loss. The device is then recharged by the same means.

Ultracapacitors

Capacitors use static electricity (electrostatics) generated between conducting metal plates, which are separated positive and negative charges. They are non-toxic, have an exponentially longer charge efficiency, and cost/weigh less than chemistry batteries.
