Lithium-ion based energy storage

Lithium-ion based energy storage

Danish Technology company ABB announced this week the successful commissioning of Denmark’s first urban energy storage system in the form of a Lithion-ion based battery energy storage system (BESS). The project, commissioned by Radius, DONG Energy’s electrical grid division, will be integrated with the local electricity grid in the new harbour district of Nordhavn, Copenhagen.

Giandomenico Rivetti, Managing Director of ABB’s High Voltage Products business unit said “We are delighted to implement this innovative solution which will help improve the security of power supplies and further support Denmark’s integration of renewable energy. This is an excellent example of ABB’s strategy of being able to supply eco-efficient and innovative solutions to the energy sector.

“As one of the key players in the smart energy revolution, ABB sees energy storage solutions as key part of the future grid in order to efficiently utilise renewable energy.”

In Denmark renewable energy sources such as wind and solar generate the majority of electricity supplied to the grid so this new battery storage system will play a major role on the country’s energy system. Due to the intermittent nature of renewable energy production the storage facility will be a key element of energy supply. ABB’s flexible and modular system can be used for different functionalities such as peak load shaving and frequency response.

“By integrating battery storage in Nordhavn we have the opportunity to learn more about how new technological solutions and market mechanisms interact with the grid,” said Knud Pedersen, Chairman of the Board at Radius, “I expect, that battery technology, on the longer horizon, holds the potential to reduce the load on the grid and make it run more cost-efficiently.”

The battery energy storage system is part of the “EnergyLab Nordhavn” project implemented in the Nordhavn district of Copenhagen. The project aims to develop and demonstrate energy solutions of the future. This includes providing valuable knowledge to help realize a more flexible and sustainable electricity grid with large amounts of renewable energy. These solutions are crucial for reaching the ambitious goal of turning Copenhagen into the world’s first carbon neutral capital in 2025.

“EnergyLab Nordhavn – new urban energy infrastructures” is a four-year project (2015-19) developing future energy solutions. It uses Nordhavn as an urban living laboratory and demonstrates how electricity, district heating, energy-efficient solutions and electrical transport can be combined into an intelligent, flexible and highly-optimised energy system. The project partners include The Technical University of Denmark, City of Copenhagen, By & Havn, HOFOR, Radius, ABB, Balslev, Danfoss, Clean Charge, METROTHERM, Glen Dimplex and the PowerLab facilities. Funding for the project is supported by the Danish Energy Agency.

In the UK this week VLC Energy, a joint venture formed by VPI Immingham and renewable investment fund Low Carbon, announced a similar project albeit on a larger scale with the total amount of energy storage capacity expected to be 50MW.

The joint venture between the two has been set up to fund early stage energy storage and renewable energy projects in the UK to complement VPI Immingham’s existing combined heat and power (CHP) generation. It is as part of this project that they intend to build two large-scale energy storage plants in Cleator in Cumbria and Glassenbury in Kent, with a combined capacity of 50MW (35MWh). The intention is then to have both connected to the grid by the end of the year.

Low Carbon CEO Roy Bedlow said: “Renewable energy is playing an increasingly important role in the UK’s energy mix and as this role expands, the development of energy storage plants will be central to the future success of the UK’s energy network.

“Furthermore, by actively building a robust portfolio of renewable energy projects at scale, we are substantively challenging the causes of climate change, while helping to meet the growing demand for renewable energy in the UK.”

The two projects will feature LG Chem lithium batteries and NEC management systems. VPI Immingham chairman and member of Vitol executive committee Russell Hardy said: “Batteries perfectly complement renewables and gas and together offer a cleaner, more efficient energy future for the UK.”

As with the Danish model when operational the two plants are expected to enhance National Grid’s ability to manage surges in supply from renewable energy sources as well as provide enhanced frequency response to the UK electricity grid among other services.

As renewable energy makes up a significant amount of our energy mix reliable energy storage is the next step to increasing our renewable capacity by negating the intermittency issue. At ILI Energy we have already commenced on our own energy storage project with pumped storage hydro.

However we appreciate that a mix of storage solutions will be required in order to maximise our renewable energy output. Therefore we are delighted to see lithium-ion based technology make the leap onto the commercial grid both here in the UK and in Denmark.

As the technology advances and costs reduce we can envision numerous lithium based storage facilities appearing throughout the grid network. As this will in part help secure our clean energy future projects such as these have our full support.
