Hydrogen: Targeting $1/kg in 1 Decade

Abstract

The societal energy system is evolving rapidly as the impacts of our existing energy system are better appreciated and advances in wind and solar energy technologies have dramatically decreased the cost of renewable resources. Simultaneously, the importance of energy transfer across timeframes (e.g., dispatchable generation, long-duration storage) and the difficulty of decarbonizing the industrial loads and transportation demands using electricity are being recognized. These changes result in a much greater need and role for hydrogen and electrochemical technologies. This need has resulted in a major focus across the globe on developing and implementing different hydrogen-relevant technologies to meet cost targets that enable large-scale commercial viability and deployment. At the center of this need is achieving low-cost clean hydrogen in the near future.
