As more and more renewables come onto grids around the world, peak loads and peak production curves will shift dramatically, causing usage spikes at times when grid operators are used to seeing dips and seemingly random spikes in generation when the wind picks up. To smooth out these curves and … [continued]
Four Phi Suea solar homes being developed in Chiang Mai, Thailand, will convert excess energy into hydrogen and store it in fuel cells. Here is how the energy system functions: During daytime, excess solar power from PV panels is directed to run electrolyzers and produce hydrogen. Said hydrogen can then be … [continued]
German energy giant Siemens has a solution in the works to tap the unused wind-powered electricity that goes to waste at night because no one is up and about. The planet’s daily temperature swings stir up night-time winds, just when no one needs electricity. Solving the storage issue is especially … [continued]
In a study published in a recent issue of Chemical Communications, a team of researchers from Virginia’s George Washington University explain a revolutionary way to make lime cement that releases zero CO2 emissions – and costs less too. After coal-powered electricity, cement manufacture is the next biggest emitter of greenhouse gases, because … [continued]
A lab at MIT, led by Dr. Daniel Nocera, have invented a new and novel form of storing energy that may prove to be an important milestone in the development of alternative energy. In fact, the obvious utility of the process has engendered a bit of excitement, but this excitement has also generated some misconceptions about the process that I would like to clear up, now that I have a more complete understanding of how it works.
