Owners and operators of data centers are increasingly focused on sustainable energy sources such as wind, solar, and hydro technologies, which contribute to environmental improvement.
FREMONT, CA: Google has committed to achieving carbon neutrality on a 24/7 basis by 2030; Amazon Web Services (AWS) aims to achieve 80 percent renewable energy in data centers by 2024 and 100 percent by 2030, and Microsoft aims to achieve 70 percent renewable energy in data centers by 2023.
While powering data centers with renewable energy is a popular industry aim, significant obstacles are to overcome. While all data centers share a commitment to renewable energy, they must balance environmental aims and the requirement to offer clients uninterrupted service. Natural energy sources fluctuate, necessitating the development of reliable, cost-effective energy storage devices.

The data center industry has yet to settle on a standard method of renewable energy storage. However, as the deadlines for achieving objectives approach and data centers expand their efforts to meet environmental goals, a significant potential in data center energy storage is emerging.
Difficulties Associated with Energy Storage
Performance: To properly strike a balance between environmental goals and service reliability, energy storage technologies must meet certain performance parameters. Owners and operators of data centers must be certain that energy storage systems will function properly, reserving power until it is required and then releasing it as intended. While modeling and simulation can assist in demonstrating performance, the most effective method of gaining industry acceptability is through real-world adoption by industry leaders.
Cost: According to the US Department of Energy, energy storage technology contributes to between 30 percent and 40 percent of the entire cost of an energy system. While certain energy storage devices have functioned satisfactorily, they have proven too expensive for general implementation. A significant component of establishing an industry standard for renewable energy storage in data centers will be determining an affordable solution—for adoption, implementation, and operation.
Regulations: While laws have generally encouraged businesses to pursue green initiatives, an uncertain regulatory environment has significantly stifled energy storage innovation. Uncertain regulatory environments have fostered a fear of large-scale energy storage investment, impeding technical innovation and uptake.
Cooperation: Developing a sustainable data center energy storage system will involve collaboration across industries—between data center owners and operators, utility companies and agencies, public safety agencies, regulators, and insurers.
