6 FAQs about [Profit analysis of energy storage and cooling system]
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.
How do business models of energy storage work?
Building upon both strands of work, we propose to characterize business models of energy storage as the combination of an application of storage with the revenue stream earned from the operation and the market role of the investor.
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).
What is the total energy consumption of a liquid cooling data center?
The total energy consumption includes the energy consumptions of the cabinets, uninterruptible power supply (UPS), cooling system, lighting system, power transfer, and distribution system. The PUE of the liquid cooling data centers can usually be reduced to below 1.3 [6, 7].
What is the energy-saving ratio of waste heat-driven cooling system?
Due to the coupled energy-saving effect of the proposed system with waste heat-driven cooling, waste heat-driven power generation and UPS replacement with energy storage batteries, the energy-saving ratio of the proposed system reaches 26.2 %, which is higher than the other energy-saving methods. Table 2.
