Sodium-ion (Na-ion) batteries, a much more abundant and cheaper alternative to the standard Lithium-ion, are on the verge of commercialisation, explain Carlos Ruiz, Martina Lyons, Isaac Elizondo Garcia and Zhaoyu Wu at IRENA. Though there’s enough Lithium in the world to support global electrification targets, tightening demand and supply chain constraints point at the urgent need for an alternative. The cost of a Na-ion battery cell is expected … [Read more...]
U.S. Residential Distributed Solar: still getting cheaper, installation and permitting too, more batteries
John Rogers at UCS reviews the new and comprehensive “Tracking the Sun” report from Lawrence Berkeley National Laboratory which covers both residential and non-residential “grid-connected, distributed” solar PV systems in the U.S. There has been clear progress across the board, including PV module efficiency, system costs, installation and permitting, and the uptake of batteries. For example, median efficiency for modules in residential systems … [Read more...]
Latest U.S. modelling shows Battery Storage can support an 80% Renewables grid by 2050
NREL’s latest Storage Futures Study concludes that battery storage should be able to support an 80% renewables grid mix in the U.S. by 2050. Madeline Geocaris at NREL explains how they modelled hundreds of future scenarios to accurately represent the value of diurnal (<12 hours) battery energy storage. The high-storage scenarios made different cost and performance assumptions for storage, wind, solar PV, and natural gas. 15 storage … [Read more...]
Record Renewables additions for 2021 and 2022 despite supply bottlenecks prove Solar & Wind’s resilience
Despite – or perhaps because of – global market and political turmoil, renewable power is set to break another record in 2022. That’s after 2021 also saw record new capacity from solar, wind and other renewables worldwide. It’s mainly driven by solar PV in China and Europe as governments around the world take advantage of renewables’ energy security and climate benefits, according to the IEA’s latest Renewable Energy Market Update. 295GW of new … [Read more...]
U.S. DoE: National Roadmap for Grid-Interactive Energy-Efficient Buildings
Buildings account for more than 70% of U.S. electricity use and one-third of economy-wide CO2 emissions. Andrew Satchwell at the Lawrence Berkeley National Laboratory presents the U.S. Department of Energy’s comprehensive plan, “A National Roadmap for Grid-Interactive Efficient Buildings”, that could deliver up to $200bn in savings to the U.S. power system and cut CO2 emissions by 80m tons per year by 2030 (6% of total power sector emissions). … [Read more...]
