As the world considers how to establish a path toward limiting the rise in global temperatures by curbing emissions of greenhouse gases, it is widely recognized that the power-generation sector has a central role to play. Responsible for one-third of total global carbon emissions, the sector’s role is, in fact, doubly crucial, since decarbonizing the rest of the economy vitally depends on the growing demand for renewable electricity (for example in electric vehicles and residential heating).
Most projections suggest that in order for the world’s climate goals to be attained, the power sector needs to decarbonize fully by 2040. And the good news is that the global power industry is making giant strides toward reducing emissions by switching from fossil-fuel-fired power generation to predominantly wind and solar photovoltaic (PV) power.
However, the rising share of renewables in the power mix brings with it new challenges. Not least of these are the structural strains on existing power-generation, transmission, and distribution infrastructure created by new flows of electricity and by the inherent variability of renewables, including potential imbalances in supply and demand, changes in transmission flow patterns, and the potential for greater system instability. One answer, explored in a new industry report with insights and analysis from McKinsey, is long-duration energy storage (LDES). The report, authored by the LDES Council, a newly founded, CEO-led organization, is based on more than 10,000 cost and […]
