Green Technology

Howard University, Washington, DC, has entered into a partnership with Parento Energy to create a microgrid for the university campus.

Mircogrid growth is being driven by concerns about the robustness of the national energy infrastructure as well as green jobs and green technology growth.  Along with the smart grid they are seen as the futur

e way power will be brought to users.

Can your car - or your hybrid - help power the grid?

" ... exploring plug-in hybrid electric vehicles (PHEV) that not only use grid electricity to meet their power needs, but also the car's potential to store electricity from the wind or sun, or even feed electricity back into the grid, earning money for the owner."

" ... vehicle-to-grid (V2G) integration ... improve the sustainability and resilience of the transportation and electric power infrastructures ... new era in which vehicles and electric "fuel" infrastructure become a system."

" electric cars become "distributed" storage, doubling as mobile holding tanks for electricity, ready to serve in their down time."

As both wind and solar power are intermittent - unlike gas, coal, oil or nuclear fired power plants - there is a need for an effective way to store these energy sources until they are needed.  The ability to smooth the supply with the demand is becoming more important as solar and wind start to power the grid.

Compressed Air Energy Storage - CAES " ... stores off-peak energy, in the form of compressed air in an underground reservoir, and releases this energy during peak hours. ... used for load management of intermittent renewable energy resources or as a stand-alone intermediate generation source for capturing energy arbitrage, capacity payments and ancillary services. ..."

"Renewable power sources are critical to addressing climate change. CAES greatly enhances the value of renewable power sources by (1) storing energy produced by renewables when demand is low and releasing it when it is needed, and by (2) rapidly providing power in the event of a sudden loss of renewables generation. ..."
