: Researchers at Imperial College London (ICL) have recently developed a predictive model that can be used to determine the lifetime cost of 9 electric energy storage technologies in 12 different applications from 2015 to 2050. The conclusion of the model is that lithium-ion batteries will be the cheapest technology in the next few decades. The results of this research have been published in the journal Joule.

Researchers at Imperial College London (ICL) have recently developed a predictive model that can be used to determine 9 types of electricity storage in 12 different applications between 2015 and 2050 The lifetime cost of the technology. The conclusion of the model is that lithium-ion battery cells will be the cheapest technology in the next few decades. The results of this research have been published in the journal Joule.

The senior author of the paper, Iain Staffell, said: “We found that lithium-ion batteries follow the pace of development of crystalline silicon solar panels. Lithium-ion batteries used to be expensive and only suitable for small Many applications, but they are now being manufactured in large-scale quantities, and their costs are falling much faster than other energy storage technologies.'

The ICL model combines 30 Data from multiple peer-reviewed studies. Studies have shown that the cheapest energy storage mechanism at present is pumped storage combined with hydroelectric power generation. The water source is pumped to higher altitude storage tanks through backup energy, and then releases the water's gravitational potential energy when needed. However, over time, the cost of pumped storage will not decrease, while the cost of lithium-ion batteries will continue to decrease. This makes the latter the best choice for most applications after 2030.

The lead author Oliver Scht said that personally, he has always been skeptical about the energy storage technology of lithium-ion batteries, but when it comes to the overall cost of energy storage, The rate of decline in the cost of lithium-ion batteries will give it a significant advantage. In the future, although researchers cannot predict how new materials or technologies will affect market trends, they hope that the model can be used to test various technical cost and performance assumptions and help industries and policy makers make wise investment decisions.
