The last time renewable chemicals developer Gevo (GEVO: Nasdaq) was featured in this forum in August 2014, the stock was looking quite oversold around $0.50 per share. The stock had recently taken a tumble after management sold 30 million shares of the company’s common stock at $0.60 a share at the end of July 2014. The plan was to use the $19 million in new capital to upgrade a production plant in Minnesota to better produce renewable isobutanol along with ethanol fuel.

Cars powered by fuel cells or batteries are only as clean as the electricity used to produce the power source. Proponents of hydrogen fuel cells argue that fuel cells have an edge over batteries, because hydrogen can ultimately be made cleaner with innovations in hydrogen production.
Steam reforming of natural gas is the most common source of hydrogen and for the most part it is still the most cost-effective process for large-scale production of hydrogen. Since ethanol is a renewable resource, the steam reforming of ethanol has been proposed by some as a promising alternative to reforming a fossil fuel like natural gas. Until recently steam reforming ethanol for hydrogen was a topic discussed only in scientific papers. Most have dismissed this alternative for renewable hydrogen as not commercially viable.

Electric vehicles (EVs) like the Tesla Model S are powered with energy stored batteries usually sitting on the car floor. The energy is sourced from power plants that deliver electricity to outlets at homes, business or charging stations. Since most electricity generated in the U.S. is produced by burning coal, there is more likely than not a lump of coal in the ‘well-to-wheel’ analysis of the total environmental impact for the Tesla Model S.

Near the close of 2014, Nuvera Fuel Cells was acquired by NACCO, an operating company of Hyster-Yale Materials Handling, Inc. (HY: NYSE). Nuvera sells a proprietary fuel cell stack under the brand name Orion for industrial mobility, automotive and aerospace applications. The company also sells its PowerTap Hydrogen Station for on-site hydrogen generation (see image below). The purchase price was not disclosed and Hyster-Yale has not provided guidance on how the deal will impact its sales and earnings in 2015.
