With the rise of renewable energy such as solar and wind (see last month’s Wind Energy Technologies in the Spotlight here), there is a need to buffer the variable energy generated by using energy storage technologies.
Energy Storage technologies help solve two main challenges in the energy transition: 1) it makes it possible to improve the match in production of renewable energy with the market’s demand, and 2) it helps distribute when the electricity system reaches its limits. Namely, energy storage can help with distributing the produced renewable energy at times when the electricity grid is less occupied and play a role in congestion management.
Given its critical role in the Energy Transition, this month’s spotlight is on Energy Storage Technologies. We have compiled a list featuring eight (8) innovative technologies. There are many technologies available for Energy storage, but they all differ based on these key characteristics: energy density, lifespan, materials used, cost, application, efficiency and safety. Here you will find novel technologies that are in testing phase with key industry players as well as proven ones that have already been deployed in operational environments.
Zenon Energy - ESS | A battery technology to solve grid infrastructure, congestion, and solar profitability
Zenon Energy focuses on building renewable battery systems that have the same usable lifetime as solar and wind assets. Zenon developed the battery enclosure, electronics, software, and containerized designs to build simple and cost-effective systems. Zenon Energy-ESS technology has many advantages such as Extreme lifecycle - proven and tested, Safest titanium-based battery chemistry and fast charging and discharging.
QuinteQ Energy | Flywheel energy storage
Developed by the Boeing Company, and brought to the market by QuinteQ: QuinteQ Energy offers a frictionless, no-wear, modular flywheel, which is containerized and easy to move around. The QuinteQ Flywheel is unique in its unlimited cycles, low standby losses, high-efficiency, and low levelized cost of storage. This results in a fifteen-fold performance increase and cost reduction versus chemical batteries.
HBr Flow Batteries | Electricity Storage at an unrivalled cost level
Elestor’s mission to build a storage system with the lowest possible storage costs per kWh resulted in HBr Flow Batteries being made of hydrogen and bromine, two widely available resources at a global scale. Another advantage of selecting hydrogen and bromine is that these enable a high power density [W/m2] as well as a high energy density [kWh/m3], both contributing to the reduction of storage costs per kWh.
Modular Battery Solutions | High performance batteries made to power any application
ELEO provides cutting-edge battery systems with a superior energy density to power a wide variety of electric applications. The advanced Battery Management System and exceptional thermal management bring significant benefits to performance, safety and lifetime.
Mobile Electricity Generators with Renewable Energy | Reduce costs and help the environment using clean energy for your operations
This technology by Kemtecnia is meant to be used as actual diesel gen-sets -on fixed installations and mobile operations- with the benefit of using only free and renewable energies; photovoltaic and eolic, and this results in significant cost reduction -fuel, logistics, maintenance, etc. Advantages: Modular design, customizable for each client specifications, Long lifetime, more than 25 years, powerful and sustainable.
Cased-wellbore compressed air storage | Innovative technology as a geo-energy storage system
The Cased-Wellbore Compressed Air Storage (CWCAS) technology is an advanced type of Compressed Air Energy Storage (CAES) process that is designed as a versatile and cost-effective renewable energy storage system. The system uses power from renewable sources to operate a compressor to compress ambient air. The high-pressure air is then stored inside a deep well(s), cased with high-grade steel. When there is a power demand, the compressed air is extracted from the well to generate power with an expander-generator.
Mobile and stationary Battery Systems | Powering electrification by connecting generation and application
SmartGrid designs, develops, builds and instals (mobile) battery systems based on Lithium Iron Phosphate technology from 120kWh and upwards. Through modular product design, SmartGrid’s technology can support all energy storage challenges, no matter the complexity. Choose from their container-based solutions, request a custom project or go mobile with a trailer battery.
Pumped/Turbine Hydro Electric Storage system | Combining Dutch water management expertise with renewable energy in a whole new concept
Delta21 is a high water defence and an energy storage system built comprising a row of dunes and a lake of approximately 20 km2, with a pumping station and a lockable barrier. The dunes together with the lockable barrier are designed to provide sufficient protection against high seawater levels till the end of this century. Delta21 has been developed as a solution for Water Safety, Energy Storage & Nature Restoration and Recovery. Storage enables considerable reduction of renewable energy to be installed and increases the occupancy rate of the existing capacity
