New APS Report: Developing Energy Storage Technologies Among Crucial Steps Toward Increasing Renewable Electricity on Nation’s Grid
Integrate Renewable Energy On the Grid
APS (American Physical Society) developed a new report on integrating renewable energy. From the news, there are several recommendations made by the study for policy makers, regulatory agencies(DOE, FERC), forecasts providers, wind plant operators. The focus is mainly on energy storage, long-term transmission, business case and forecasting.
In addition to the perspectives in the report, I would like to make the following comments:
(1) The energy storage: besides searching for battery chemistries, it should be emphasized (worth exploring) that PHEVs could possibly act as economically viable storage devices after their usage is substantially increased (probably in need of government's promotions and subsidies).
(2) I highly agree with the viewpoint that regulatory agencies should develop response other than maintaining conventional reserve (the last point),but one aspect that should be included, besides energy storage and long-distance transmission, is the demand response. Energy conservation or consumption shifting from peak hours to off-peak hours should be considered as a new type of reserve with great value to reduce the conventional reserve.
Integrate more renewable energy! Let's make effort together.
