As the world pays more and more attention to reducing emissions and mitigating climate change, analysts believe that the most abundant element in the universe— hydrogen —has the potential to become a mainstream energy technology and a key clean fuel source in the future that could help reduce greenhouse gas emissions. In some industries, including oil refining, ammonia production, and methanol production, hydrogen is already widely used. But if hydrogen were to support the world’s energy transition and help tackle greenhouse gas emissions, it would need dozens of billions of US dollars of investment every year to overcome the barriers it faces now. These are the challenges for building the necessary infrastructure to create a true global hydrogen economy, to producing hydrogen cost-effectively from renewable sources and with zero emissions. In a nutshell, hydrogen has great potential but it needs to tackle the scale and source challenges to become […]
