Energy Storage

Overview

Energy Storage

The progressive cost reduction of renewable energy technologies has created an unstoppable growth in the demand for Renewable Energy Sources (RESs) at a global level. The intermittent nature of RESs, however, causes network planning and network stability issues for energy system operators. To overcome these issues, new energy storage facilities are required.

Today, a variety of different technologies, such as mechanical, thermal, chemical, electrochemical, and Battery Energy Storage Systems (BESS), are being further developed and are already competing on the short-, medium- and long-term energy storage device markets.

While Pumped Hydro Storage (PHS) still constitutes a 95% share of the currently installed storage capacity, various other energy storage technologies, which cover different storage durations and frequencies of power supply, are experiencing rapid growth and consequently a drop in price. Drawing on over 20 years of proven references, ILF is a leading player in pumped hydro storage and emerging technologies, supported by extensive experience in gas and power generation applications.

Moreover, ILF is involved in some of largest on and off-grid BESS projects to date for various use cases such as back-up power, frequency regulation, demand shifting and peak shaving, as well as in the planning of an advanced power-to-hydrogen facility. ILF offers the complete package of engineering services, from the early stages of project appraisal, selection of the optimal solution, to project execution.

ILF also has experience in developing technologies such as gravity storage and liquid air energy storage. ILF renders all the services required for the successful implementation of energy storage projects.
