    With the range of natural gas prices from 2016 as shown in the graph (Hydrogen Production Tech Team Roadmap, November 2017) putting the cost of steam-methane-reformed (SMR) hydrogen at between $1.20 and $1.50, the cost price of hydrogen via electrolysis is still over double 2015 DOE hydrogen target prices.

  6. Ozone - Wikipedia

    en.wikipedia.org/wiki/Ozone

    Ozone is a bent triatomic molecule with three vibrational modes: the symmetric stretch (1103.157 cm −1), bend (701.42 cm −1) and antisymmetric stretch (1042.096 cm −1). The symmetric stretch and bend are weak absorbers, but the antisymmetric stretch is strong and responsible for ozone being an important minor greenhouse gas .

  9. Droop speed control - Wikipedia

    en.wikipedia.org/wiki/Droop_speed_control

    Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid. It works by controlling the rate of power ...
