The primary objective of the GREENWELLS program is the development of chemical reactors and supporting units that economically store at least 50% of incoming intermittent electrical energy in carbon-containing liquids. To achieve attractive economics, ARPA-E expects that chemical reactors will need to be dynamically operable to optimize the entire system of renewable energy production, electrolysis capital, and energy storage. If successful, the GREENWELLS program will provide low-cost carbon-containing liquids that enable the transportation and storage of renewable energy, are suitable as-is or with upgrading for use in the difficult-to-decarbonize sectors, and will speed the development of new renewable energy projects by alleviating requirements for connection to an electric grid.
Technical approaches of interest include but are not limited to:
(1) Dynamic Reactor Design
(2) Novel Catalyst Development and Optimization
(3) Manufacturing of Modular Reaction Systems
(4) Transient Modelling and Process Optimization
