The global renewable energy industry is up against one huge challenge: How to store the massive quantities of intermittent solar and wind power it generates. This is because whenever the wind blows and the sun shines, wind turbines and photovoltaic plants frequently generate an energy surplus. Calm conditions, overcast skies and solar cycles, on the other hand, result in a lack of renewable energy production. This challenge is not limited to any particular region or sector: it’s relevant and solutions are now in worldwide demand.
Combining CMBlu’s organic flow batteries with photovoltaic or wind farms strongly decreases intermittency and flattens the renewable power generation curve. The following applications and cases demonstrate just some of the sizeable financial and sustainability benefits of our organic battery technology:
Whenever regulations require an intraday balancing of production and consumption of green electricity, batteries are able to temporarily decouple the actual power generation process from its grid feed-in. This enables photovoltaic or wind farm operators to adapt their power production to the physical demand profile of their customers and to raise the consumers’ share of green power. This, in turn, raises the value of power sold through renewable power purchase agreements (PPAs), and the value of the PPAs themselves. Especially PPA providers can then benefit from more profitable agreements.
Depending on individual subsidies or feed-in tariffs, higher feed-in flexibility enables photovoltaic or wind farm operators to maximize their power generation revenues (for example by preventing losses when prices dip below zero).
Battery-based peak shaving of the feed-in profiles prevents cut-offs in power generation when grid overload occurs. This also circumvents limited grid access capacity and helps reduce costs for overall grid development.
Here, hybrid solutions such as offshore wind farms combined with organic flow batteries and hydrogen electrolyzers are able to optimize the costs, energy efficiency and sustainability of entire cross-sector systems. In these cases, CMBlu batteries buffer the volatility of wind power generation and raise the full load hours of the electrolyzers.
Of course, all of these behind-the-meter measures are complemented by selling free battery capacity to the electricity markets. Energy arbitrage in the day-ahead and real-time or intraday markets, together with profitable opportunities in ancillary services, will generate considerable added revenues. Finally, CMBlu will provide an integrated AI-based software platform to tap into this full value chain, from optimized battery operation to full electricity market access.
