How to promote energy storage construction

Why do we need energy storage technology?

With the continuous growth of renewable energy sources such as solar and wind energy, the demand for energy storage technology is becoming increasingly urgent. Photovoltaic and wind power generation systems have fluctuating production capacity due to weather and other factors, while energy demand is all-weather.

Why is storage important in a building?

Storage sited at buildings can serve as important resources to promote grid reliability and flexibility, increase renewable penetration, and increase energy resilience. Current thermally driven loads make up more than 45% of the annual electrical energy consumed on-site in residential and commercial buildings (Figure 1).

Are energy storage systems safe for commercial buildings?

For all of the technologies listed, as long as appropriate high voltage safety procedures are followed, energy storage systems can be a safe source of power in commercial buildings. For more information on specific technologies, please see the DOE/EPRI Electricity Storage Handbook available at: TABLE 1. COMMON COMMERCIAL TECHNOLOGIES

What is energy storage?

Basics of Energy Storage Energy storage refers to resources which can serve as both electrical load by consuming power while charging and electrical generation by releasing power while discharging. Energy storage comes in a variety of forms, including mechanical (e.g., pumped hydro), thermal (e.g., ice/water), and electrochemical (e.g., batteries).

What are the benefits of thermal energy storage?

Advances in thermal energy storage would lead to increased energy savings, higher performing and more affordable heat pumps, flexibility for shedding and shifting building loads, and improved thermal comfort of occupants.

How does energy storage work?

Energy storage can smooth both the momentary, and longer term fluctuations in power from intermittent renewable resources. There are currently no revenue streams associated with smoothing the short term fluctuations in power since the electric grid provides these same services at no cost.
