PG&E’s 75MW Energy Storage Procurement to Test Flywheels, Zinc-Air Batteries Some new technologies alongside lithium-ion in California’s latest big utility storage round In choosing their first round of procurements to meet the state’s 1.3-gigawatts-by-2020 energy storage mandate, California’s big investor-owned utilities have largely stuck to tried-and-true lithium-ion batteries — until now. On Wednesday, Pacific Gas … Continue reading #PGE ’s 75MW Energy Storage Procurement to Test Flywheels, Zinc-Air Batteries→
Toronto Hydro Pilots World’s First Offshore Compressed-Air Energy Storage Project A set of pipes running nearly two miles out into Lake Ontario are part of a novel project to help Toronto Hydro extend the life of its distribution equipment. The two-year pilot is not another tidal energy project — it’s the first test of an … Continue reading Toronto Hydro Pilots World’s First Offshore #Compressed-Air Energy Storage Project→
Some energy storage already cost competitive, new valuation study shows A new report from Lazard breaks down the costs of 8 different storage technologies Asessing the value of energy storage is one of the burning issues facing the electricity sector today, and a new valuation matrix from the firm Lazard could give utilities and policymakers … Continue reading Some energy storage already cost competitive, new valuation study shows→
MESA, vanadium batteries put to the test in Pacific Northwest The future of utility-scale energy storage could soon be on display in the Pacific Northwest. Three Washington state utilities are deploying a total of five cutting-edge systems that will be evaluated by the Pacific Northwest National Laboratory in Richland, Wash. Three of the systems were … Continue reading MESA, #vanadium batteries put to the test in #Pacific_Northwest→
Despite green outcry, CPUC approves SoCal Edison gas & storage plans SCE’s LCR-RFO was challenged on several fronts by a variety of stakeholders. The Sierra Club, for instance, argued that certain contracts with affiliates of NRG Energy did not meet the requirements for a demand response resource or even a preferred resource under the LCR-RFO … Continue reading Despite green outcry, #CPUC approves #SoCal_Edison gas & storage plans→
Why The Future For Energy Storage Just Got Brighter The energy storage market is rapidly becoming one of the most exciting spaces in all of renewables. Unlike solar, wind, coal, and natural gas power which are all substitute forms of generation, there really is no other mechanism to perform the function of energy storage outside … Continue reading Why The Future For Energy Storage Just Got Brighter→
New type of ‘flow battery’ can store 10 times the energy of the next best device Industrial-scale batteries, known as flow batteries, could one day usher in widespread use of renewable energy—but only if the devices can store large amounts of energy cheaply and feed it to the grid when the sun isn’t shining and … Continue reading New type of ‘flow battery’ can store 10 times the energy of the next best device→
LEVELIZED COST OF STORAGE ANALYSIS Energy storage systems are be rated in terms of both instantaneous power capacity and potential energy output (or “usable energy”). The instantaneous power capacity of an energy storage system is defined as the maximum output of the invertor (in MW, kW, etc.) under specific operational and physical conditions. The potential … Continue reading LEVELIZED COST OF STORAGE ANALYSIS→
STORING ENERGY IN LIQUID FORM Researchers in Singapore have created a new kind of redox flow battery with an energy density around ten times higher than conventional redox flow batteries. Never heard of a redox flow battery? These rechargeable batteries have more in common with fuel cells than conventional batteries. They use two circulating liquids … Continue reading STORING ENERGY IN LIQUID FORM→
