Photo voltaic, wind fully exchange diesel at South Pole Station – pv journal Worldwide


Researchers from Argonne National Laboratory have concluded that renewable vitality can partially exchange diesel gas to energy devices and supply warmth to the South Pole. They suggest a hybrid photo voltaic, wind and vitality storage that may cut back diesel consumption by 95% and save roughly $57 million in 15 years, after an preliminary funding of $9.7 million.

Scientists from Argonne National Laboratory and National Renewable Energy Laboratory (NREL) of the US Department of Energy (DOE) are investigating the potential for utilizing renewable vitality to energy the Amundsen-Scott South Pole Station in Antarctica.

The facility, the place local weather change and cosmology research are carried out, makes use of solely non-renewable vitality sources to energy devices and warmth scientists.

“All the vitality on the South Pole is at present produced by diesel gas and a generator,” stated Amy Bender, a physicist in Argonne’s High Energy Physics division and the corresponding writer of the analysis paper. “We’re asking whether or not a shift to renewables is feasible. This examine is the start of attempting to make that case.”

New analysis examines the feasibility of photo voltaic, wind turbine mills, lithium-ion vitality storage, and long-term vitality storage on web site in numerous mixtures, with and with out present diesel vitality technology.

“We did an in depth evaluation of which sort of battery is finest relying on whether or not you are utilizing photo voltaic or wind or each for energy,” stated Sue Babinec, program lead for stationary storage. within the Argonne. “The sorts of batteries you want for renewable vitality energy do not simply have to final for years, they should present vitality for an extended time frame.”

The group concluded that the least-cost system consists of three sources of vitality technology and lithium-ion vitality storage. To provide the 170 kW of energy wanted by the station, it proposes a hybrid system consisting of 180 kW of photo voltaic panels, 570 kW of wind generators, and a 3.4 MWh lithium-ion storage system battery vitality.

Researchers estimate that this technique can cut back diesel consumption by 95% in comparison with a full diesel configuration, leading to roughly 1200 metric tons of carbon footprint prevented annually. Using NREL’s Renewable Energy Integration and Optimization software program, the researchers estimated that the system would require an preliminary funding of $9.7 million. They say the funding pays for itself in gas value financial savings in simply two years, and can finally save roughly $57 million over 15 years.

The evaluation, Techno-economic evaluation of renewable vitality technology within the South Pole, was printed in Renewable and Sustainable Energy Reviews.

“The DOE and universities all over the world are attempting to decarbonize our six continents,” stated Ralph Muehleisen, chief constructing scientist and group supervisor for Buildings & Industrial Technologies at Argonne, “They’re simply beginning to get to Antarctica, so we’re now truly, for the primary time, speaking about decarbonizing the world.
