Each of the three parameters is useful to systematically differentiate investment opportunities for energy storage in terms of applicable business models.
Is energy storage a profitable business model?
Although academic analysis finds that business models for energy storage are largely unprofitable, annual deployment of storage capacity is globally on the rise (IEA, 2020). One reason may be generous subsidy support and non-financial drivers like a first-mover advantage (Wood Mackenzie, 2019).
How can energy storage be profitable?
Where a profitable application of energy storage requires saving of costs or deferral of investments, direct mechanisms, such as subsidies and rebates, will be effective. For applications dependent on price arbitrage, the existence and access to variable market prices are essential.
What is a business model for storage?
We propose to characterize a “business model” for storage by three parameters: the application of a storage facility, the market role of a potential investor, and the revenue stream obtained from its operation (Massa et al., 2017).

How will China's solar PV supply chain change in 2027?
China's shares within each of the different stages of the supply chain for solar PV would also remain stable for cells and modules, fall modestly for wafers, and increase modestly for polysilicon through to 2027. The slight changes are primarily due to project announcements in India, Thailand, the US and Vietnam.
How did China control the global solar market?
The increased installed capacity, the heavy manufacturing, and the availability of materials on its domestic land allowed China to control the global solar market by imposing quotas and restrictions on importing countries. We have shown that China alone installed more than 50 % of the total Asian solar capacity in the span of 25 years.

Are energy storage business models fully developed?
E Though the business models are not yet fully developed, the cases indicate some initial trends for energy storage technology. Energy storage is becoming an independent asset class in the energy system; it is neither part of transmission and distribution, nor generation. We see four key lessons emerging from the cases.

With the rise of intermittent renewables, energy storage is needed to maintain balance between demand and supply. With a changing role for storage in the ener-gy system, new business opportunities for energy stor-age will arise and players are preparing to seize these new business opportunities.
Can energy storage disrupt business models?
Energy storage has the potential to disrupt business models. Energy storage has been around for a long time. Ales-sandro Volta invented the battery in 1800. Even earlier, in 1749, Benjamin Franklin had conducted the first ex-periments. And the first pumped hydro storage facili-ties (PHS) were built in Italy and Switzerland in 1890.
Do energy storage technologies compete with other solutions?
Energy storage technologies compete with other solu-tions to deliver or absorb power when needed. Existing solutions, like grid expansion or more interconnections, the establishment of a capacity market for gas-fired pow-er plants or strategic reserves, still receive a great deal of attention from policy makers, regulators and system op-erators.
