Hydrogen's Role in Decarbonization
- Hydrogen's decarbonization potential is debated, with proponents viewing it as key and others questioning its viability.
- The need for decarbonization solutions and market opportunities drive interest from various industries.
Hydrogen for Excess Renewables
- Hydrogen is proposed for utilizing excess renewable electricity and providing energy storage during periods of low renewable generation.
- However, the economics of hydrogen production for this purpose, especially considering intermittency, are highly unfavorable.
