Power systems have always required flexibility to adapt to changes in demand and resource availability. Integrating renewable energy sources, such as wind and solar, is posing new challenges as these sources are weather-dependent. The growing share of renewables in power generation is leading to a need for increased flexibility in power systems to ensure reliability, affordability, and cleanliness. Experts highlight the importance of a diverse range of energy technologies to meet this challenge, with a focus on addressing seasonal variations and supporting decarbonization. Green hydrogen is identified as a key player in providing flexibility by offering solutions such as blending with natural gas, supporting hard-to-abate sectors, and acting as an energy storage medium. Projects like the ACES Delta in Utah demonstrate the potential of energy storage through carbon-free hydrogen production. As renewable energy penetration increases, finding the right mix of solutions, including a combination of renewables, natural gas, and hydrogen, will be essential to navigate the evolving energy landscape.
