The most viable stationary energy storage solution for grid applications

Periodic Reporting for period 1 - Nano-Edison (The most viable stationary energy storage solution for grid applications)

Reporting period: 2019-08-01 to 2019-11-30

Grid stability is an increasingly challenged as power distribution evolves to a more decentralized model with progressively higher shares of renewable energies. Battery energy storage systems (BESS) are emerging as potential solutions to increase system reliability, due to their unique capability to absorb, hold and reinject electricity, as well as offer ancillary grid services. However, mature BEES technologies for grid-scale applications are still expensive, have limited lifespans and carry inherent risks.

By applying its patented nanotechnology, GreenVolt has developed Nano-Edison, the first BESS that meets all the criteria for grid-scale applications (safe, environmental, low-cost, scalable), simplify the associated infrastructure and provide key grid balancing services. The achievement of these objectives is perfectly aligned to current smart grid challenges to achieve safer, cleaner and more competitive electricity supply, enabling thus the transition towards renewable energies.
Technical upgrades have been defined and scheduled, including testing and validation stages, and an industrialization route. Commercial strategy has been confirmed based on the urgent needs of grid-scale BESS by transmission and distributor system operators, upward trend of the involved markets, and absence of both direct competitors and conflicts with IPR. We performed a risk assessment to make sure that the most relevant risks are identified and set a contingency plan. We also valued participation in related-events as strategy to attract new clients and partners. Revenue streams, pricing and cost revision were established, resulting in a business opportunity for Greenvolt of 5-year estimated profitability of 32.8 M€ (ROI = 10.7) and 30 new employees.
Owing to its disruptive nanotechnological design, Nano-Edison battery offers: (i) specific power ≥200W/kg, (ii) charge/discharge efficiencies over 99.9%, (iii) depth of discharge of 100% (vs. 80% of Li-ion and lead-acid batteries) (iv) service life of 20,000 cycles (x8 higher than Li-ion batteries) and (V) very competitive manufacturing costs <90 €/kWh (comparable to pump hydro-storage). In addition, Nano-Edison is extremely tolerant to fire/explosion hazards and made of non-toxic materials. The result is a solution that can answer European grid challenges of reduce costly fluctuations in frequency, voltage and power flow cause by the progressively more decentralized model and with higher shares of renewable energies.
