SAN DIEGO, Jan. 22, 2021 /PRNewswire/ — Two many years following becoming the 1st battery of its type to be connected to the California grid to support assist trustworthiness and maximize the use of clean strength, the vanadium redox flow (VRF) battery centered at a San Diego Gasoline & Electrical substation is once more breaking new ground. This time, the emerging battery technological innovation is being tested as a indicates to enable obtain zero-emission microgrids – a resource to maintain communities and vital amenities run with thoroughly clean energy through adverse weather conditions disorders and Community Security Electric power Shutoffs.

With the assist of Japan’s New Energy and Industrial Engineering Advancement Corporation (NEDO) and the California Governor’s Place of work of Business and Financial Advancement (GO-Biz), SDG&E and Sumitomo Electric powered (SEI) launched the demonstration venture in 2017. The collaboration was not long ago prolonged for a further year as a result of the stop of 2021, to further test the battery’s microgrid capabilities and optimize its means to assist the grid with ancillary expert services these types of as voltage and frequency regulation. As opposed to the most common power storage technologies (stacked cells of lithium-ion batteries), the move battery getting analyzed is composed of tanks of liquid electrolytes and pumps. It commenced collaborating in the California Unbiased Process Operator’s (CAISO) wholesale electrical energy markets in December 2018 and was used last summer to support decrease the effects of rotating outages during a document heatwave.
“Long-length electricity storage and microgrids are each key to assisting California satisfy its clear electrical power, reliability and resiliency goals. We need breakthrough technologies to accomplish 100% renewable electricity on our grid and to power microgrids through emergencies,” mentioned SDG&E CEO Caroline Winn. “SDG&E is very pleased to enjoy a position in creating revolutionary remedies, like the stream battery technology, to support address California’s local climate-associated issues.”
Circulation battery devices have an envisioned lifespan of far more than 20 yrs and could have less degradation over time from repeated charging cycles than other chemical battery technologies.
“This venture is slicing-edge and serves as the proving floor for integrating stream batteries into microgrids,” NEDO Govt Director Sato Yoshiteru stated. “We are decided to add towards establishing revolutionary answers to environmental and electrical power troubles, these as bettering grid trustworthiness, which are amid the most vital concerns for the State of California.”
“I would like to express my deepest gratitude to GO-Biz, San Diego Gasoline & Electric powered and NEDO for implementation of the Sumitomo flow battery in California. This is a trusted, extensive-length technologies that gives a large diploma of operational flexibility and hearth safety, using non-flammable and re-usable electrolyte. Based on these rewards, I’m self-assured the move battery contributes to grid trustworthiness in California. I am established to help California arrive at its thoroughly clean power ambitions. I appear forward to continuing our partnership with San Diego Gas & Electric,” stated Hideo Hato, Senior Handling Director of Sumitomo Electrical.
In 2015, NEDO signed an settlement with GO-Biz to exam stream battery overall performance in a demonstration placing. NEDO then contracted with Sumitomo to put into practice the project. The move battery supplies 2 MW/8 MWh of strength, plenty of to power the equivalent of about 1,000 houses for up to 4 hrs.
“California has confirmed time and once more that addressing local weather modify is great for our natural environment, it can be excellent for long run generations, and it’s excellent for our economic climate – spurring new technologies and creating new markets on a regular foundation,” reported Tyson Eckerle, GO-Biz’s Deputy Director of Zero Emission Vehicle Market place Improvement. “We keep on to be proud global partners with NEDO as this game-changing technological innovation brings new alternatives and renewed economic expansion by renewable electrical power.”
Given that unveiling the project in 2017, SDG&E has been researching if stream battery technology can economically enhance the supply of dependable power to clients, integrate escalating amounts of renewable strength and boost the adaptability of grid functions. Like other electrical power storage programs, the stream battery absorbs or releases electrons as necessary to assist keep grid stability. For case in point, soaking up surplus solar vitality produced in the center of the working day and discharging it to the grid all through peak evening several hours.
SDG&E has been a chief in integrating power storage, as effectively as building microgrids. In 2013, SDG&E started functioning the to start with utility-scale microgrid in The united states – the Borrego Springs Microgrid. Past calendar year, it acquired a federal grant to upgrade the Borrego process to operate on 100% renewable power. In 2017, SDG&E unveiled what was then the world’s greatest lithium-ion battery storage facility. To day, SDG&E has about 100 MW of strength storage jobs finished or contracted and is performing to insert much more.
