How does 4th power energy storage work?

Fourth Power said its energy storage system converts renewable energy, such as solar or wind power, to thermal energy, which can be stored until needed. The thermal battery heats (Figure 2) liquid tin, and then moves it through a piping system (Figure 3) to “heat stacks of carbon blocks until they glow white hot (Figure 4).

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.

Why should you invest in fourth power?

With the support of our investors, Fourth Power will accelerate our mission and reshape the clean energy landscape by making grid-scale thermal battery storage the most cost-effective solution for power production. We are energized by the opportunity to create a better, more sustainable future.”

What is 4th power used for?

4. Fourth Power’s carbon blocks are used to store energy at record-breaking temperatures. They glow white hot and transfer heat back to electricity via thermophotovoltaics, or TPV. Source: Fourth Power

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.
