Variable renewable energy (VRE) is forecast to reach 50% of total generation by 2050. To balance the inherent variability, a surge in storage technology with respect to grid power and quality is expected. The most popular technology, lithium ion battery storage does not come without its constraints. Read Peter Lo’s writing on the trends surrounding storage and variable renewable energy.
Rapid acceleration of changes in the energy sphere renders preparations for their implicit challenges difficult. Bloomberg’s recently published 2018 New Energy Outlook (NEO) highlights key market drivers and integrates insight from a variety of experts to evaluate how the energy market will evolve in the coming decades.
From a pragmatic perspective, the electricity system will have to technologically adapt to enable these trends without inflating costs or dangerously destabilising the system. Electrical Engineer, Alex Kleidaras reviews some of the claims of NEO, with regards to their implications and requirements for their feasibility.
A modern grid supplying modern electricity demands should be able to provide environmentally friendly energy securely and at an affordable price at once. There are a number of technology pathways being suggested to modernise the electricity grid, and adapt it to the new reality of distributed variable renewable generation. This article gives an overview of these technologies.
