Abstract

In 2012 VUB carries out a project for the GDF SUEZ, called "Intermittent RES". This project assesses the environmental impact of the growing share of intermittent electricity production. In order to increase the percentage renewable energy in the production of electricity, the share of wind energy needs to increase. However, wind powered electricity production does not follow the demand side of the electricity market, as it is highly influenced by the wind speeds varying each moment. In electricity system with high penetration levels of wind energy there is a need for flexible producers to balance the differences between demand and production side. The "Intermittent RES" project focuses on the environmental impact of thermal balancing plants like flexible gas turbines and turbojets. This 'business as usual' balancing will create an extra burden for the production of one kWh from wind energy.

However there are innovative approaches to balance the electricity system, avoiding the impact of thermal balancing plants. This project wants to assess these promising new technologies on their environmental point of view. Electricity storage is a promising method that can balance the intermitency and allow unused electricity to be used later on. There are many storage systems available for back-up such as pumped hydro storage, batteries, fly wheels, electrochemical capacitors, etc. It is important to assess the environmental performance of storage systems in order to ensure the sustainability of wind and PV electricity. Life cycle assessment of these storage systems could make it possible to know and compare the environmental impacts of different storage systems. The objective of this project is to conduct a cradle-to-grave life cycle assessment of different storage systems to balance intermittent RES.
