In November, the Nebraska Public Power District (NPPD) announced a partnership with Finland’s Lappeenranta University of Technology and Wärtsilä, a Finnish manufacturer, to explore using that company’s technology to generate electricity from methanol, which would be synthesized by combining hydrogen and carbon dioxide.
While a news release touts the study as intending to help “accelerate the move towards a future where energy will be produced from 100 percent renewable carbon free sources,” NPPD does not yet know whether any carbon reduction benefits will result. Read more here.

ASU engineers break solar cell record, ASU News
Arizona State University researchers continue to break solar cell efficiency records in an effort to harness the sun’s energy more economically as a renewable source for electricity. Last year, Assistant Professor Zachary Holman and Assistant
Research Professor Zhengshan “Jason” Yu in ASU’s Ira A. Fulton Schools of Engineering set a world record of 23.6 percent
efficiency for a tandem solar cell stacked with perovskite and silicon.
The number was a few percentage points shy of the
theoretical efficiency limit for silicon solar cells alone. Now, the team improves upon the record by nearly two percentage points, to 25.4 percent, in a joint project with researchers at the University of Nebraska–Lincoln, predicting they’ll be nearing 30 percent tandem efficiency within two years.

Stanford scientists locate nearly all U.S. solar panels by applying machine learning to a billion satellite images, Stanford University News. Stanford researchers have identified the GPS locations and sizes of almost all U.S. solar power installations from a billion images. Using the data, which are public, they identified factors that
promote the use of solar energy and those that
discourage it. Photo: Telesis Inc’s solar array in Lincoln
