What is fourth power's approach to utility-scale energy storage?

Fourth Power's approach to utility-scale energy storage considers the expected growth of wind and solar generation.

How does 4th power work?

Fourth Power’s system converts renewable energy to heat, or thermal energy, which can be stored until needed. The thermal battery heats liquid tin and moves it through a piping system to heat stacks of carbon blocks until they glow white hot. The system then exposes thermophotovoltaic (TPV) cells to the light and converts it into electricity.

Why should you choose fourth power?

With Fourth Power’s solution, the renewable energy that would otherwise be wasted due to curtailment can be stored for over a month and discharged over any period from a few hours to a few days while maintaining the lowest possible cost. Fourth Power can meet today’s short-duration (5-hour) needs and the future’s longer-duration (100-hour) needs.

Why is 4th power a grid-scale battery?

Each subsystem of Fourth Power’s thermal battery is separately housed – this allows energy and power to be scaled independently. Grid-scale, long-duration batteries must have flexible discharge rates and reaction times to give grid operators complete control over how and when the stored energy is used.

Who is the EVP of Engineering at 4th power?

Huang will serve as EVP of Operations, leading the creation of Fourth Power’s project execution engine, which will productize designs for high-speed deployment. As EVP of Engineering, Schweiger will spearhead product development validation and build the engineering team necessary for large-scale deployments.
