A selection of ten companies are developing advanced solutions such as mobile flood barriers, solid-state batteries, and nuclear reactors to combat climate change. These firms exemplify key shifts in climate technology, including energy-intensive AI infrastructure. The list aims to highlight the most impactful players tackling urgent environmental issues.
WeLion New Energy has advanced its semi-solid-state battery technology, achieving an energy density of 824 wh/kg in testing during 2025. The company previously released a battery pack with 360 wh/kg in partnership with Nio, supporting over 1,000 km of range, though production costs limited its scale. Additionally, WeLion is developing batteries for maritime applications and exploring higher energy densities.
BYD Executive Vice President Stella Li said the company is in a "leading position" on solid-state battery technology and will release its first vehicle using the tech in 2027. This aligns with earlier statements from BYD battery subsidiary FinDreams, which said mass production of sulfide-based solid-state batteries would follow around 2030, with lithium iron phosphate batteries still used alongside them in lower-tier models.
