Environmental assessment of swedish all-vanadium liquid flow energy storage battery

What is a vanadium flow battery?

The vanadium flow battery (VFB) can make a significant contribution to energy system transformation, as this type of battery is very well suited for stationary energy storage on an industrial scale (Arenas et al., 2017 ). The concept of the VFB allows conver electrical energy into chemical energy at high efficiencies.

Are lithium-ion and vanadium flow batteries environmental burdens?

This study investigates the environmental burdens of lithium-ion and vanadium flow batteries, focusing on their life cycle and their use for renewable energy storage in grid applications.

Are vanadium redox flow batteries good for the environment?

While the production of vanadium redox flow batteries led to the highest impact values for six categories including global warming potential, 184 kg CO 2 eq/kWh; and cumulative energy demand, 5200 MJ/kWh.

Does a life cycle assessment affect the environmental impact of Ow batteries?

The present study focuses on using life cycle assessment to evaluate the environmental impact associated with the industrial-scale production of flow batteries and the corresponding sensitivity to materials selection decisions.

How many cycles can a vanadium redox flow battery withstand?

A vanadium redox flow battery can withstand up to 15,000 cycles, with one in Japan reported to have exceeded 200,000 cycles. However, the upper limit reported in the literature is in the range of 10,000–15,000 cycles.

Are flow batteries a promising technology for stationary energy storage?

Among the various types of battery storage systems, flow batteries represent a promising technology for stationary energy storage due to scalability and flexibility, separation of power and energy, and long durability and considerable safety in battery management ( Alotto et al., 2014; Leung et al., 2012; Wang et al., 2013 ).
