Today, only 5 percent of New Jersey’s total electricity generation is from renewable sources. This is mostly solar with some biomass and wind. However, the 2019 NJ Energy Master Plan sets a goal of 100 percent of the state’s energy needs coming from clean energy by 2050. There are many pieces to hitting this target, but the state has mandated that 50 percent of its electricity should come from renewable sources by 2030. For example, 3,500 megawatts (MW) of offshore wind generation capacity is a part of this mandate. This figure represents 20 percent of today’s 18,000 MW of total electric generator capacity.
Eos Energy Storage, the leading manufacturer of safe, low-cost and long-duration zinc battery storage systems, today announced that it has partnered with EPC firm Nayo Tropical Technology Ltd. to deploy the company’s Aurora EnergyBlock™ battery energy storage system (BESS). Eos’ EnergyBlock is part of a project to bring power to underserved areas and will integrate into rural microgrid developments beginning in the African country of Nigeria. Results from the deployment of this microgrid BESS solution will give utilities and energy providers options for the best storage technologies for rural locations and environments.
Japanese telecoms giant Nippon Telegraph and Telephone (NTT) is plotting a major renewables play in the country, investing up to US$1 billion a year up to 2030. National newspaper Nikkei reported earlier this week that NTT is planning to invest some ¥1 trillion (US$9 billion) to establish itself as a major player in Japan’s renewable energy market, deploying utility-scale generation and electricity transmission and distribution to complement its existing business units.
More than 500 residential energy storage batteries will be aggregated into a virtual power plant (VPP) by US utility Portland General Electric (PGE), with some participating households offered US$5,000 rebates on battery system purchases as well as money off their monthly electricity bills.
The COVID-19 pandemic has served as a “test case demonstration” for grid reliability with a higher use of renewables in recent months, according to Deloitte Consulting. Through mid-June, renewable energy overtook coal generation in the mix for 116 days, compared to 39 days in 2019. A Deloitte Resources 2020 study, discussed on Wednesday at a panel on the pandemic impacts of energy management, anticipates a growing level of wind and solar penetration, despite the pandemic and ensuing economic conditions.
Researchers in the Cockrell School of Engineering at The University of Texas at Austin have built a new type of battery that combines the many benefits of existing options while eliminating their key shortcomings and saving energy. Most batteries are composed of either solid-state electrodes, such as lithium-ion batteries for portable electronics, or liquid-state electrodes, including flow batteries for smart grids. The UT researchers have created what they call a “room-temperature all-liquid-metal battery,” which includes the best of both worlds of liquid- and solid-state batteries.
The consolidation of the top two residential solar companies in the U.S. comes as both companies have adapted to growing demand in the distributed solar sector. Sunrun offers energy storage and grid services, working with utilities and grid operators on virtual power plants that combine distributed energy systems. Sunrun expects to offer battery storage to the combined base of nearly 500,000 solar customers.
“ESA commends the House Select Committee on the Climate Crisis for continuing to prioritize meaningful recommendations that include support for a stand-alone investment tax credit for energy storage. Energy storage is an enabling technology that aligns with the Committee’s focus on grid resilience, achieving net zero emissions, and bringing clean and advanced energy sources to our electric grid. We thank the Select Committee for understanding the importance of a storage ITC to foster resilient, efficient, sustainable and affordable electric service. ESA encourages Congress to pass legislation that includes a storage ITC with a direct payment option to support economic recovery and make the American economy more resilient.”
Scientists led by MIT have suggested chitin, a carbon and nitrogen-rich material made from waste shrimp shells, could produce sustainable electrodes for vanadium redox flow batteries and other energy storage technologies.
In the previous edition of PV Tech Power, we spoke to four leading developers of solar-plus-storage and standalone energy storage projects about what it takes to get projects over the line, their experiences in the field – and what sort of technologies are making their efforts possible. This time around, we’ve spoken in depth with two of the system integrator/ manufacturers that supply that segment of the energy storage market. Danny Lu, vice president at Powin Energy and Dr Zhuang Cai, R&D director at Sungrow, share their insights on what it means to build lithium-ion battery storage systems at scale.
