Hydrogen is a central pillar of the energy transformation required to limit global warming under two degrees Celsius. To achieve such-degree scenario, the world will need to make dramatic changes year after year and decrease energy-related CO2 emissions by 60% until 2050 – even as the population grows by more than 2 billion people and billions of citizens in emerging markets join the global middle class. Hydrogen can play seven major roles in this transformation:
- Enabling large-scale renewable energy integration and power generation
- Distributing energy across sectors and regions
- Acting as a buffer to increase energy system resilience
- Decarbonizing transportation
- Decarbonizing industrial energy use
- Helping to decarbonize building heat and power
- Providing clean feedstock for industry.
In all seven application areas, hydrogen can offer economically viable and socially beneficial solutions. In our vision, hydrogen enables the deployment of renewables by converting and storing more than 500 TWh of otherwise curtailed electricity. It allows international energy distribution, linking renewable-abundant regions with those requiring energy imports. It is also used as a buffer and strategic reserve for power.
