In addition, despite the rigorous development of renewables, carbon dioxide emissions are increasing, because the energy mix increasingly includes coal-fired power plants that emit large quantities of CO 2 to compensate for weather-related fluctuations in power generation from renewables and the closing of nuclear plants.
The objective of this topic is to fund high risk, high reward research efforts that will revolutionize technologies that capture carbon dioxide from coal-fired power plants, thereby preventing release into the atmosphere. Grid-Scale Rampable Intermittent Dispatchable Storage (GRIDS).
Some continue to burn coal, for example, because there are no other economically feasible choices for them. “We Efficient coal-burning plants Shutting down coalpower plants completely is unlikely to happen anytime soon, he predicted, especially since many countries are building new ones that have 40-year life spans.
And the Norwegian company H2Carrier recently received approval in principle for its concept for an industrial-scale floating production unit to make green ammonia at sea. Almost all hydrogen produced today is designated as brown, black, or gray, meaning it was generated by burning natural gas or coal.
Sven Thesen, the communication and technology director for Better Place , a start-up that is gaining traction (see this recent New York Times article ) in its effort to create a network for electric cars in various countries, likened the concept of electric cars to cellphones. Fifteen years ago, how many people had a cellphone?”
Grid Stability : Storing energy in the form of hydrogen helps stabilize the powergrid. By converting excess renewable energy into hydrogen, we can prevent overloading the grid. For example, some steel plants are experimenting with hydrogen to replace coal in the steelmaking process.
Audi Volkswagen-owned company exploring PHEVs Metroproject Quattro Sub-compact PHEV Concept Car shown October 2007; PHEV of A1 Sportback under consideration Bright Automotive For-profit spin off from Rocky Mountain Institute designing lightweight PHEVs, successor to RMIs 1990s "Hypercar" concept. Has shown some concept fuel-cell PHEVs.
That need for balance is true of electric powergrids, too. Spiking demand for electric heat collided with supply problems created by frozen natural-gas equipment and below-average wind-power production. Packetized energy management (PEM) allows the powergrid to flexibly handle a varying supply of renewable energy.
A January 2007 Pacific National Laboratory study shows that if we woke up tomorrow and all our vehicles could plug in, todays grid could support more than three-quarters of them charging at night without building a single power plant. Dont PHEVs just shift pollution from gasoline cars to power plants?
The winds had barely died down when electric-power specialists and others began calling for a radical overhaul of Puerto Rico’s electricity networks, one that would emphasize renewable energy, distributed generation, and, critically, microgrids. A microgrid is like a miniaturized, tightly controlled version of a powergrid.
It’s very similar to the infrastructure for electric cars because the idea, ultimately, for electric cars is that you also are revamping your grid to facilitate, whatchamacallit, intermittent renewable energy sources, like wind and solar, because having an electric car that runs off a coal-fired power plant is defeating the purpose, essentially.
