High density thermal storage arrangement
An energy transportation and grid support system utilizes at least one transportable containment module capable of storing thermal or chemical energy typically produced from renewable or geothermal sources and providing connectivity with energy conversion equipment typically located in a land or sea-based operating facility. The system includes circuitry to hookup to an adjacent electricity grid for the provision of grid support and/or piping to move thermal energy typically used to drive steam turbines generating electricity. The operating facility also includes a communication arrangement to link with and exchange operations control data with a grid or heating operator and the energy transportation operator. The invention is directed to both apparatus and method for the energy transportation and grid support system.
1. A method of providing supplementary power for an electrical grid network and storing of energy in periods of excess electrical energy comprising transporting a charged large capacity thermal based energy storage arrangement from an energy producing first geographic region having a source of energy used to charge said large capacity thermal based energy storage arrangement to a net energy consuming second geographical region; the large capacity thermal based energy storage arrangement being positioned within a ship hull of a ship; the method comprising;
connecting the large capacity thermal based energy storage arrangement to an energy producing electrical grid network;
using the energy producing electrical grid network in selected periods of excess electrical power to power a plurality of embedded electrical heaters in said large thermal based energy storage arrangement to convert and store the excess electrical power as thermal energy in said large capacity thermal based energy storage arrangement;
moving said ship from the energy producing first geographic region to the net energy consuming second geographical region;
connecting said large capacity thermal based energy storage arrangement to a thermal energy conversion system;
connecting said thermal energy conversion system to an energy consuming electrical grid network;
using thermal energy from said large capacity thermal based energy storage arrangement to circulate a working fluid powering said thermal energy conversion system and produce electrical power for the energy consuming grid network to supplement the power thereof.
2. A method as claimed in claim 1 wherein said energy is stored as thermal energy in graphite cores of said large capacity storage arrangement.
3. A method as claimed in claim 2 including off-loading in a marine receiving arrangement said large capacity storage arrangement and continue to at least primarily support large capacity storage arrangement by buoyancy thereof in a water body.
4. The method of claim 1 further comprising the step of:
replacing said large capacity thermal based energy storage arrangement with a second large capacity energy storage arrangement located on a second ship when the energy stored in said large capacity thermal based energy storage arrangement is greatly less than the energy in said second large capacity energy storage arrangement.
