thermochemical

And some investors argue that Range Fuels and others using what is called a thermochemical process to convert cellulosic material have the best chance of success.

But Nernst showed in 1906 that it is possible with the aid of the third law, to derive the necessary parameters from the temperature dependence of thermochemical quantities.

STAR-H2 is an adaptation for hydrogen production, with reactor heat at up to 800°C being conveyed by a helium circuit to drive a separate thermochemical hydrogen production plant, while lower-grade heat is harnessed for desalination (multi-stage flash process).

Small nuclear power reactors 2009

Outlet temperature of over 900°C and aiming for 1000°C enables thermochemical hydrogen production via an intermediate heat exchanger, with electricity cogeneration, or direct high-efficiency driving of a gas turbine (Brayton cycle).

Generation IV nuclear reactors 2009

Its fuel is in 'prisms' and its main purpose is to develop thermochemical means of producing hydrogen from water.

This could be used in thermochemical hydrogen manufacture.

Temperatures range from 510°C to 1000°C, compared with less than 330°C for today's light water reactors — this means that four of the reactors can be used for thermochemical hydrogen production.

Generation IV nuclear reactors 2009

Operating temperature of 550°C is readily achievable but 800°C is envisaged with advanced materials to provide lead corrosion resistance at high temperatures and this would enable thermochemical hydrogen production.

Generation IV nuclear reactors 2009

A secondary coolant system is used for electricity generation, and thermochemical hydrogen production is also feasible.

Generation IV nuclear reactors 2009

They employ similar reactor technology to the VHTR, for power generation, thermochemical hydrogen production or other process heat.
