100’s of GW of Solar and Wind based Renewable Energy (RE) systems has been deployed. With increase in scale the costs have decreased which had made RE projects not just sustainable but also economical compared to fossil fuel sources. The biggest hurdle in the continued deployment is due to the intermittency of both Solar and Wind.
The section highlights key use case of Delectrik’s products. In general, any application that requires at least 4 hrs of daily storage is a potential application. While the energy density of Flow Batteries is lower compared to solid state batteries the area required on stationary application especially couple with PV the area required is insignificant. In 1 acre of space 50 MWH of Flow Battery can be deployed which is ~2% of the space required for PV in terms of equivalent energy production.
Reach out to us with specific requirements and Delectrik will help with the techno-commercial assessment. Typically, daily load profile, current energy mix (costs, availability), potential to add on-site solar, geographic location is all is required for first pass assessment.
Round the Clock (RTC) or Firm Dispatchable Renewable Energy (FDRE) Projects
A lot of recent RE projects now require Round the Clock or Firm Dispatchable RE. Long -duration Flow Batteries can be coupled with PV/Wind to provide firm predictable power. The exact storage sizing depends upon the location and the yearly spread of Solar and Wind power availability.
Energy Shifting
The intermittent nature of Solar and Wind limits their daily availability to less than a third. Addition of Long duration storage allow’s storage of excess RE and shift it to times when it is not available. The combined cost of energy is still favorable compared to the cost of the alternative grid tariff.
OFF Grid Mining or other Industrial Sites
Several industrial operations globally such as mining sites are not connected to the mainstream grid. These rely on Diesel to carry out their operations. Substituting Diesel with Solar and Flow Batteries makes it a very compelling use case both in terms of economic and sustainability with attractive ROI’s.
Off-Grid Remote Communities Microgrid
Several inhabited regions of the world lack access to conventional grid electricity. Given the remote nature and or less occupancy makes for the regular electricity distribution infrastructure unviable. Decentralized Electricity in the form Solar and Flow Battery ESS based microgrid can serve these remote communities.
Commercial and Industrial (C&I)
The power tariff for Commercial and Industrial units is typically highest among all consumers. With the drop RE prices C&I units have started adding RE plants either on-site or off-site with feed in tariffs. These consumers can only offset a part of their demand from RE. Long duration storage allows complete or near complete transition to clean, sustainable and affordable electricity.
Industrial/Warehousing Real Estate
The Decentralized electric system of PV + ESS + EV Charging in an opportunity for real estate developers of Industrial and Warehousing companies to embed these in their original plan. Today’s real estate developers can become mini electric utilities of the Future.
EV Charging
The transition to electric vehicle’s requires a transition on similar scale would be required to electricity charging infrastructure. Since, the current penetration of EV’s is still a small percentage of overall vehicles, using RE and Flow Batteries present a cost-effective and sustainable way to charge the EV’s. This is especially viable for fleet or logistics companies where large scale charging stations can be setup.
Residential
Residential scale rooftop solar are increasingly being deployed globally. The size is limited by the daytime load as the excess energy typically is wasted or even in presence of net-metering policies the returns are unfavourable. This is driving the demand for home storage systems. Safe and long-life Flow Batteries of sizes 10 – 40 kWh is a great addition to solar home systems for meeting most of the daily requirements of typical home.
