Abstract
Beneficial use structures are disclosed that include coal combustion residuals (“CCR”) mixed with water and a binder to form a structural material, and adapted to be compacted for use in the formation of the beneficial use structure. Various structures having beneficial uses are described, including compressed air storage facilities and a pumped hydroelectric facility, including such a facility adapted for use with a lock system of a waterway.
Claims9
A beneficial use structure, comprising coal combustion residuals (“CCR”) mixed with water and a binder to form a structural material, and adapted to be compacted for use in formation of the beneficial use structure, wherein the beneficial use structure includes a pumped water storage reservoir, comprising:
- a. a base constructed of compacted CCR to increase the height of the storage facility to a predetermined amount above surrounding terrain and thereby provide for greater stored potential hydro energy;
- b. a water storage impoundment constructed on the base and constructed from a material selected from the group of materials consisting of at least one layer of roller-compacted concrete or strengthened CCR;
- c. drains positioned in a bottom of the impoundment;
- d. conduits connected for water flow from the drains;
- and
- e. at least one hydroelectric pump/generator connected to the conduits for receiving water outflow from the impoundment to generate electricity for use during peak use periods to supplement electricity generated by conventional electric utility generators and in low utilization periods to pump water into the impoundment through the drains.
A beneficial use structure, comprising coal combustion residuals (“CCR”) mixed with water and a binder to form a structural material, and adapted to be compacted for use in formation of the beneficial use structure, wherein the beneficial use structure is a pumped hydroelectric facility adapted for use with a lock system of a waterway, comprising:
- a. a base constructed of compacted CCR and positioned on a terrain for increasing the elevation of the hydroelectric facility about the lock system of the waterway;
- b. a water impoundment having raised walls constructed of a material selected from the group consisting of compacted concrete and compacted low leaching and low permeability strengthened CCR;
- c. a lock filling piping system that interconnects the water impoundment with the lock system of the waterway for increasing the fill rate of the lock system to permit an increased rate of transit of vessels through the lock system;
- d. intake pipes positioned upstream of the lock system for receiving water from the waterway;
- and
- e. a hydroelectric generator/pump facility for receiving water from the intake pipes and generating electricity from movement of the water from the intakes pipes through the hydroelectric generator/pump facility.
