E – 2022 2022 Grid Energy Storage Technology

In this online engineering PDH course, an abridged version of the Department of Energy’s 2022 Grid Energy Storage Technology Cost and Performance Assessment is presented. The Assessment is part of DOE’s effort to provide a standardized approach to analyzing the cost elements of grid energy storage technologies, engaging industry to identify these various cost elements, and projecting 2030 costs based on each technology’s current state of development. Some of the technologies are relatively unknown except to specialists in the field, for example, gravity-based storage systems consisting of heavy bricks lifted by a crane, a heavy piston lifted by pressurized water in a mine shaft, or heavily-loaded railroad cars moved up a hill. Other technologies such as batteries of various types, compressed-air energy storage, pumped storage hydropower, thermal energy storage and hydrogen are also considered.
