Our pathway toward decarbonization and achieving the 1.5° Celsius target necessitates supportive regulatory frameworks mandating energy-efficiency measures across the commercial, industrial, and residential segments. It also requires significant economic investments driving renewables and the switch to nuclear low-carbon and large-scale CCUS technologies. Interest in hydrogen as a low- or zero-carbon energy carrier has grown in recent years. Many governments acknowledge that a hydrogen-based economy could be the best alternative to the present fossil fuels-based economy and an answer to concerns over carbon emissions, energy security, and climate change.

Though the promise of hydrogen as an essential tool in catalyzing the transition toward a sustainable energy economy is huge, its current application is mostly limited to the industrial sector. Many projects across power generation, transport, and other segments are still in their pilot stages and require technological and cost breakthroughs for increased adoption. There is still a long way to go, and it will likely take another 10 to 20 years before the hydrogen economy becomes mainstream across the global power sector and other segments.
