Our planet’s climate is changing at an alarming rate, in large part due to anthropogenic or human-induced emissions. To scale back these emissions, countries around the world are adopting clean, renewable energy sources, which are becoming more cost-effective than their polluting counterparts in many places. With use limitations facing existing renewables, the world strives to achieve net-zero emissions; Hydrogen will complement other low or zero-carbon energy sources and become a key component of our planet’s clean energy mix, particularly by decarbonising hard-to-abate industries such as steel, cement, aviation, and shipping.
