Are VRFBs a promising energy storage candidate?

With a plethora of available BESS technologies, VRFBs are widely considered a promising energy storage candidate. The uniqueness of VRFB is the possibility to set independently the power of the battery by the size of the device and the energy for the battery by the size of the tank for liquid reagents.

Can VRFB be recycled?

On another side, VRFB is aqueous, which implies lower costs on thermal management in comparison with other BESS. In parallel, vanadium electrolyte can be 100% recycled. Existing VRFB still have a low energy density. Our collaborative project is focused on this problem.

How do infra funds help wind and solar projects in Sweden?

Infra funds like GreenVoltis play a key role in providing structured financing to improve project bankability and long-term profitability. An increasing number of wind and solar developers in Sweden are expanding into BESS project development, but grid constraints remain a significant hurdle. Limited grid connection capacity is slowing deployment.

What are the disadvantages of VRFB?

However, the main drawback of VRFB is the low power per area of the electrode/cell, which implies that the cell must be large to produce a certain amount of power and/or that multiple cells must be assembled in parallel to increase the power, which increases the costs.

How will the mfrr market change?

mFRR market changes - such as the transition to 15-minute settlement periods and price-area-based pricing—will drive higher volatility and greater profit opportunities. BESS will increasingly be paired with renewable projects - boosting value creation and grid stability.

How will wholesale electricity markets affect mfrr?

Wholesale electricity markets will play a greater role - particularly in southern Sweden (SE3 and SE4), where price spreads are similar to Germany. mFRR market changes - such as the transition to 15-minute settlement periods and price-area-based pricing—will drive higher volatility and greater profit opportunities.
