Energy storage in long-term system models: a review of considerations, best practices, and research needs

Collaborations between academia and industry are growing in scope, duration, and sophistication. The best collaborations recognize the unique strengths and skill sets of both parties and are structured to leverage what each party does best. In many cases, these collaborations develop into long-term relationships, and it is important to develop the systems and structures needed to support these relationships to ensure that they meet the needs of both sides. Successful collaborations require the formulation of a governance structure to facilitate communication, decision-making, assessment of progress, and the inevitable changes of direction that accompany product development. This panel explored the pragmatic aspects of successfully structuring collaborations and managing the relationships after the deal is done. Several dominant themes associated with successful collaborative relationships emerged from the discussion, and these will be explored in this article.

Short And Long Term

For renewable energies to succeed in replacing fossil fuels, large-scale and affordable solutions are needed for short and long-term energy storage. A potentially inexpensive approach of storing large amounts of energy is through the use of a concentration flow cell that is based on cheap and abundant materials. Here, we propose to use aqueous iron chloride as a reacting solvent on carbon electrodes. We suggest to use it in a red-ox concentration flow cell with two compartments separated by a hydrocarbon-based membrane. In both compartments the red-ox couple of iron II and III reacts, oxidation at the anode and reduction at the cathode. When charging, a concentration difference between the two species grows. When discharging, this concentration difference between iron II and iron III is used to drive the reaction. In this respect it is a concentration driven flow cell redox battery using iron chloride in both solutions. Here, we investigate material combinations, power, and concentration relations.
