My conception is based on my developments of some years in a field of energy cheapening and sustainability and other novel technologies would be shortly disclosed below.
We can use a technological chain: remote solar power plants and/or wind ones - chemical energy (ammonia, RNH3) - liquid ammonia (liquefied at 20 bars) - delivering for consumers (up to 1000-s km by pipes) - electricity in local micro-grids. If remote poor settlements, trucks can distribute cheaply the said ammonia from a net of district ammonia storage tanks.
(1) The ammonia can be transformed in hydrogen by heating created by a small part of the said ammonia, and the said hydrogen can be transformed into electricity with very high energy efficiency if using hydrogen-air fuel cell being quite cheap device.
(2) Very cheap RE-electricity of much less than USD 0.01/kWh by high temperature heat (down to USD 0.001/kWh or cheaper) is offered and disclosed here too.
It allows RNH3 to be USD 20.0/ton + small CAPEX using metal-hydrogen/nitrogen chemical cycles with hydrogen of USD 0.1/kg if using the said cheap RE-energy.
(3) Such cheap H2 can be created by the water splitting at ~ 2500 Centigrade with a help of microwaves concentrated at the RE power plant remotely or by the RNH3 heating locally. Microwaves RF generators can be very energy effective and very simple, cheap and small device for such purpose.
Other attractive things are possible.
By one pipe of 1.0 m2 and 5 m/s we can deliver 3,000 MW power for some thousand km distance, and a cost of the delivery and energy consume for it is relatively negligible.
NH3 liquid is 680 kg/m3, so 5 * 680 * 3 * 286,000 kJ/ (2 * 18 * 17) = 4.800.000 kW. For 70% energy efficiency of H2-air fuel cell, it is 3,300 MW.
High temperature heat of about USD 0.001/kWh (CAPEX is about USD 10.0/kW) per unit
you can see in http://judbarovski.livejournal.com/133020.html (âSolar energy can be extremely cheap and all the year round, 9.03.2016). Arrays of a planar mirrors paired with a dish concentrators of 1 m2 each, so with a focal spot being motionless, they can be made of thin foils and thin sheets, and controlled by tiny and cheap sensors and servomotors.
The wind power can be very cheap too (see http://judbarovski.livejournal.com/136757.html , âBreakthrough concept of VAWT (vertical axis wind turbine)â, 11.19.2016). It is a chain of the VAWT-s lifted in the sky, and each the VAWT rotates in opposite direction to neighboring ones.Â It allows sufficiently to compensate torsion loads and to diminish a time of response to variable load on the total wind turbine. I firmly recommend not wide blades and not big power capacity to be used for one device.
The higher in the sky, the stronger wind and much more wind power can be harvested.Â
ItÂ isn'tÂ needed in any energy storage and land area consume. It can work in any place of land area in the Earth or offshore.
Metal-hydrogen/nitrogen fuel cell can be considered as a transformer of the heat in electricity with highest energy efficiency, because it can be recycled by decomposing of a product of its electrochemistry by concentrated solar heat (see in http://judbarovski.livejournal,com/84244.html (âNew type of ECG-Updatedâ. 12.15.2013).
Metal-hydrogen/nitrogen chemical cycle for ammonia production can be, for example:
(a) 3 CaH2 +N2 = Ca3N2 + 3 H2
(b) Ca3N2 + 6 H2 = 3 CaH2 + 2 NH3, and we can use several analogous processes instead it, with the same incredible cheap ammonia, here is USD20.0/ton NH3 calculated byÂ stoichiometry with my very cheap RE-energy and H2 (see above) + small CAPEX.
The water splitting to produce incredible cheap H2 was shorty, but clear disclosed above (also seeÂ http://judbarovski.livejournal.com/133945.html - âWater splitting down to 10 cents/kg H2 by microwave generatorâ, 9.18.2016).
Mobile application of the said electricity for urban traffic you can see, as an example, in http://judbarovski.livejournal.com/138073.html , âSelf-driving car as a grid element and its batteryâ, 12.12.2016). It is specially designed cheap urban EV-s powered from a city grid and equipped by tiny and cheap rechargeable battery used for emergency only.
Instead of the ammonia as energy delivery carrier we can use very
cheap artificial carbon based fuelsÂ made ofÂ CO2 and above mentioned cheap H2 (see
http://judbarovski.livejournal.com/134477.html , 9.20.2016).
For waste CO2 exhaust capture we can use two different technologies (see
(a) http//judbarovski.livejournal.com/132709.html , âSolvecolab-MIT,
Prize for CO2 sequestration from carsâ, 8.15.2016).
