Clean energy technologies play a crucial role in combating climate change by significantly reducing harmful emissions. Low emissions hydrogen, produced through water electrolysis, offers promise in industries where emission reduction is challenging. Renewables like solar and wind energy need expedited deployment to meet targets effectively. Electric vehicles show promise, but their adoption in emerging markets requires attention. Carbon capture storage faces challenges due to high costs, necessitating a hub model for faster scalability. Additionally, smart grids are vital for efficiently managing electricity supply and demand. To unlock the full potential of these technologies, global efforts are needed to address gaps and accelerate their deployment for a greener future.
