Imagine a device that fits inside a pair of shoes, harvests the energy leftover from walking and stores it in AAA or watch batteries. At the Center for Research in Advanced Materials (CIMAV) in Chihuahua, Mexico, scientists have done just that.
An unusual, groundbreaking solar plus energy-storage microgrid project in Rutland, Vt., was recently announced. The Stafford Hill Solar Farm is being developed by Green Mountain Power in collaboration with Dynapower and GroSolar.
While battery innovators have continued to tweak their products’ chemistries in search of the perfect, safe and affordable companion to rooftop photovoltaic (PV) panels, a number of energy-storage entrepreneurs have made an end-run around this technology conundrum.
A group of researchers at the Massachusetts Institute of Technology (MIT) say liquid metals could provide the solution to the solar energy-storage problem, ensuring that the power is available at all times and not just when the sun is shining.
It seems like, every other week, a leading research lab announces a breakthrough technology to make batteries more powerful, more durable or a whole lot less expensive—after just a few more years of research and development.
Solar photovoltaics and electric vehicles (EVs) are two shining stars of the sustainable-energy movement. Despite their growing market shares, limitations remain, and few would have guessed that pairing these technologies would offer relief.
New York recently strengthened its power supply with the completion of two projects: an underground and underwater 660-megawatt electric transmission project between New Jersey and Manhattan and a low-cost, commercial battery-storage system on the campus of the City College of New York (CCNY).
If wind- and solar-generated electricity are changing the way we look at our relationship to the grid, the transformation is only visible when the sources of that generation are in full force or, more specifically, when the gusts are strong and the sun is high.
According to the National Alliance for Advanced Battery Technology, the confluence of powerful trends underway across the nation’s electrical-energy system is driving the need for a drastically different approach to managing the grid system in the 21st century.
Thus far, the structure and integrity of the grid have limited the deployment and effectiveness of intermittent alternative energies, such as solar photovoltaics (PV). The sun may not always shine enough to meet demand.
