Zinc Batteries Power Stationary Energy Storage
As solar, wind and other renewable resources play a larger role on the power grid, renewables’ essential partner—energy storage—must keep pace to provide power at peak hours when the sun doesn’t shine, and the wind doesn’t blow.
Rechargeable zinc batteries offer an ideal energy storage solution; they can release power back to the grid for many hours or even days at a time. With numerous chemistries and design innovations, zinc batteries increasingly meet residential, commercial and microgrid energy storage market needs and demonstrate zinc’s capabilities and benefits in stationary storage.
COMMENTARY
One of the well-developed zinc battery chemistries is zinc-bromine flow, which proves ideal for both small commercial uses and for medium to large grid-sized applications. The energy is stored in a zinc bromide solution, which flows continuously past the electrodes, where it reacts and generates electricity. This liquid-based battery is non-flammable, long-lasting, fully recyclable and tolerates a wide range of temperatures. The batteries also are scalable for medium or large-scale projects.…
Two Killed in Collapse of Coal Pile at Colorado Power Plant
Two employees of a company that manages coal-handling operations for Xcel Energy’s Comanche Generating Station in Colorado were killed June 2 when they were trapped in a coal pile that collapsed at the power plant.
The collapse happened Thursday morning about 8:30 a.m. Mountain time, according to officials. Rescue crews located the victims Thursday afternoon. Officials said the victims, whose names were not immediately released, were working on the 80-foot-high pile of coal. Officials said it is not known what the workers, sub-contractors from Savage Services, were doing at the time of the incident.
Comanche is a three-unit coal-fired plant. Comanche’s 857-MW Unit 3 is the largest coal-burning unit in Colorado.
Pueblo Fire Inspector and Public Information Officer Erik Duran told media, “EMS emergency services responders on site determined that [the victims] were dead on scene.” Duran said responders recovered the bodies of “two men, one in his 20s and one in his 30s. We reached the first victim at around 3 p.m.…
The POWER Interview: How Solar Can Solve the C&I Power Puzzle
Commercial and industrial (C&I) enterprises rely on their power supply. Many facilities, such as hospitals, federal institutions, and military bases—those considered mission critical—have long been at the forefront of finding solutions to keep their lights on.
In today’s world, the need for reliable and resilient power is critical for a wide range of industries. Uninterrupted power is essential, not only for operations but also for safety. Power outages can bring economic disaster for businesses that don’t have a power system that can ensure the lights don’t go out.
That’s why more and more C&I enterprises are installing their own power generation systems, to keep their business up and running. Many are embracing renewable energy solutions as part of their sustainability efforts, recognizing the importance of decarbonization as they design their own onsite generation, or as they purchase power from others—be it solar power, wind power, or another distributed energy resource.
Kirk Edelman, chief commercial officer with New York City-based Safari Energy, a solar energy company, answered questions from POWER about the solar industry and how it fits within the growing need for commercial and industrial facilities to produce their own power to ensure a reliable and resilient supply of electricity.
GE Turbines Will Equip Vietnam’s First LNG-Fueled Power Plant
Two units of a new gas-fired power plant in Vietnam will feature the first use of General Electric’s (GE’s) H-Class turbine in the country.
GE on May 16 announced that PetroVietnam Power Corp.’s (PV Power’s) Nhon Trach 3 & 4 Power Plant, with 1.6 GW of generation capacity, will use two GE 9HA.02 gas turbines. It also will be the first power station in Vietnam fueled by liquefied natural gas (LNG).
The new units are expected to provide electricity for three large industrial areas in the southern region of the country including Ho Chi Minh City, Dong Nai, and Ba Ria–Vung Tau provinces.
LNG projects are being developed in Vietnam as the country tries to wean itself off coal-fired power generation, which supplies about half the country’s electricity. Prime Minister Pham Minh Chinh in November of last year said Vietnam wants to achieve net-zero carbon emissions by 2050.
The country’s ruling Communist Party has said it does not want to build nuclear power plants, and in 2016 scrapped plans for reactors backed by both Japan and Russia.…
The POWER Interview: Importance of Pricing Data for Renewable Energy
The highs and lows of markets for renewable energy are driving more interest in granular pricing data. Any company embarking on a new project must do its research to ensure that it calculates the proceeds based on the right financial information. With so much data now readily available, it’s more important than ever to use the right data, and make accurate calculations.
Amid the boom in demand for renewable power plants, that is not always happening when backers go to measure the value of the energy they will generate. Here’s why, according to Jennifer Newman, vice president of Atmospheric Science Research at REsurety, the Boston, Massachusetts-based renewable industry data and analytics company, who says friends don’t let friends use “8760s.”
POWER: What is an 8760 and how is it used in the renewable energy industry?
Newman: An 8760 (sometimes referred to as a typical meteorological year or TMY) consists of hourly generation values for a wind or solar project for all 8,760 hours of a typical year.…
