Summary

Story summary

Researchers from Tokyo’s Institute of Science developed a hydrogen battery that operates at 90°C.
The battery uses magnesium hydride as the anode and hydrogen gas as the cathode, with a solid-state electrolyte.
This could enable hydrogen batteries in electric vehicles and reduce reliance on lithium-ion batteries.
In the United Kingdom, BYD has achieved an 880% year-on-year increase in electric vehicle sales, driven by affordability and government support for zero-emission vehicles.

History

Historical Context

The hydrogen economy gained traction in the 2000s, but interest surged again in the 2010s, leading to the formation of the World Hydrogen Council in 2017. By 2022, only 70,200 hydrogen vehicles were sold globally, compared to 26 million electric vehicles. The unveiling of a hydrogen battery in 2023 at Tokyo’s Institute of Science highlights ongoing innovations aimed at reducing reliance on lithium-ion technology.
