DualFlow develops a radically new energy conversion and storage concept that combines water electrolysis, battery storage and coproduction of decarbonized chemicals into one single hybrid technology using water soluble redox mediators as energy transfer vectors. The system can be operated for electricity storage or for energy conversion to hydrogen and value added chemicals. During energy storage operation, the system works as a conventional stationary flow battery. The energy conversion starts when the battery is full but there is abundant inexpensive green electricity available. Now the battery is chemically discharged in a mediated electrolysis to produce hydrogen and value added chemicals. The energy conversion is realized by pumping charged battery electrolytes through reactors. For hydrogen production, reactor is filled with catalytic particles to catalyze electron transfer and hydrogen evolution. For value added chemical production the reactor consists of biphasic system where charged electrolyte oxidizes chemicals in an organic phase. The reaction products are then extracted into the organic phase. The energy conversion operation requires only reactors and catalyst for hydrogen evolution, indicating that the additive costs of the dual circuit is minimal. The concept results in flexible system capable of both energy storage and energy conversion to hydrogen. We strongly believe that this concept offers possibilities to produce inexpensive hydrogen, in a flexible manner without utilizing any critical raw materials.

DualFlow开发了一种全新的能源转换和储存概念，将水电解、电池储存和联合生产脱碳化学品整合为一项单一的混合技术，使用水溶性氧化还原介体作为能量转移载体。该系统可用于电力储存或将能量转换为氢气和增值化学品。在储能运行期间，该系统就像传统的静止流动电池一样工作。当电池充满，但有大量廉价的绿色电力可用时，能量转换就开始了。现在，电池在中间的电解过程中进行化学放电，以产生氢气和增值化学品。能量转换是通过将充电后的电池电解液泵入反应堆来实现的。对于制氢，反应器中填充了催化颗粒，以催化电子转移和放氢。对于附加值化学品的生产，反应器由两相系统组成，带电的电解液在其中氧化有机相中的化学品。然后，反应产物被提取到有机相中。能量转换操作只需要用于放氢的反应器和催化剂，这表明双回路的附加成本最低。这一概念使灵活的系统既能储存能量，又能将能量转化为氢气。我们坚信，这一概念提供了以灵活的方式生产廉价氢气的可能性，而不需要使用任何关键的原材料。
