Barely a month after the U.S. Federal Energy Regulatory Commission (FERC) licensed the nation’s first commercial hydrokinetic power station, Houston-based Hydro Green Energy in January completed installation of the first of two turbines at an existing run-of-river hydropower plant on the Mississippi River for the Minnesota city of Hastings. When the second turbine is installed later this spring, the two hydrokinetic turbines will constitute a floating array that will sit on top of a barge at the Army Corps of Engineers’ Lock & Dam No. 2.

Like the airline industry, power generators all over the world have been seeking alternative fuels with which to produce electricity, and the blends are bound to get stranger. One company is looking to make liquid fuels from chicken fat, beef tallow, and pork lard, for example. Here’s a list of innovative fuels that generators could use in the near future.

Solar panel prices have taken a 10% tumble since October last year, and they are expected to drop another 15% to 20% this year, owning to an oversupply from the mass of new factories and draining demand in Germany and Spain, where solar incentives were recently cut. In the U.S., the low prices — pushed even lower by the renewed solar tax credits that took effect on Jan. 1 and other incentives — have heightened demand, both on the distributed generation level and at utility scale.

American Superconductor Corp. (AMSC) and Northrop Grumman Corp. in January said they successfully completed a full-power test of the world’s first 36.5-MW high-temperature superconductor (HTS) ship propulsion motor.
