IMO, Nissan would be wise to utilize this technology primarily as a range extender for its BEVx vehicles of all sizes.
Electricity from the grid off-peak will always be much cheaper (and in terms of total environmental impact, usually "cleaner") that ethanol or any other hydrocarbon fuel.
Nissan to develop ethanol-based fuel cell technology by 2020
...Nissan said its technology would be ready for use in vehicles in 2020, adding it could be used to extend the range of larger, electric vehicles such as delivery vans.
It would target a cruising range of around 800 kilometers per fuelling, more than the range for gasoline-powered vehicles of just over 600 kilometers.
The automaker said running costs for the FCVs would be roughly similar to those of electric vehicles, while declining to give details on vehicle pricing...
Unlike its rivals' offerings, Nissan's technology does not require hydrogen to be stored in vehicles, reducing the need for expensive bulky hydrogen tanks, and would not require fuelling stations, which have been slow to spread globally...

Nissan announces development of the world’s first SOFC-powered vehicle system that runs on bio-ethanol electric power
YOKOHAMA, Japan – Nissan Motor Co., Ltd. announced today that it is currently researching and developing a Solid Oxide Fuel-Cell (SOFC)-powered system that runs on bio-ethanol electric power. The new system – a world first for automotive use – features an e-Bio Fuel-Cell with an SOFC power generator. SOFC is a fuel cell utilizing the reaction of multiple fuels, including ethanol and natural gas, with oxygen to produce electricity with high efficiency.
About e-Bio Fuel-Cell
The e-Bio Fuel Cell generates electricity through the SOFC (power generator) using bio-ethanol stored in the vehicle. The e-Bio Fuel-Cell uses hydrogen transformed from fuel via a reformer and atmospheric oxygen, with the subsequent electrochemical reaction producing electricity to power the vehicle.
Unlike conventional systems, e-Bio Fuel-Cell features SOFC as its power source, affording greater power efficiency to give the vehicle cruising ranges similar to gasoline-powered cars (more than 600km). In addition, the e-Bio Fuel-Cell car's distinct electric-drive features — including silent drive, linear start-up and brisk acceleration — allow users to enjoy the joys and comfort of a pure electric vehicle (EV).
Fuel-cell systems use chemicals that react with oxygen, generating power without release of harmful byproducts. Bio-ethanol fuels, including those sourced from sugarcane and corn, are widely available in countries in North and South America, and Asia. The e-Bio Fuel-Cell, using bio-ethanol, can offer eco-friendly transportation and create opportunities in regional energy production, while supporting existing infrastructure.
When power is generated in a fuel-cell system, CO2 is usually emitted. With the bio-ethanol system, CO2 emissions are neutralized from the growing process of sugarcane making up the bio-fuel, allowing it to have a "Carbon-Neutral Cycle," with nearly no CO2 increase whatsoever...
The e-Bio Fuel-Cell will realize the concept of "Nissan Intelligent Power," promoting greater efficiency and electrification of cars and the joys of driving, alongside battery EVs, such as the Nissan LEAF, Nissan e-NV200 and "e-Power," which is equipped with an engine housing an exclusive large-capacity motor and power generator...
