Heat is a type of energy, so BTU can be directly compared to other measurements of energy such as joules (SI unit of energy), calories (metric unit), and kilowatt-hours (kWh). 1 BTU = 0.2931 watt-hours. 1 BTU = 0.0002931 kWh. 1 kWh ≈ 3412 BTU. BTU/h, BTU per hour, is a unit of power that represents the energy transfer rate of BTU per hour.
RedT Energy Storage (2018) and Uhrig et al. (2016) both state that the costs of a vanadium redox flow battery system are approximately $ 490/kWh and $ 400/kWh, respectively [ 89, 90 ]. Aquino et al.
