Greenchek Technology Inc. is a hydrogen technology development company. The Company is engaged in developing, manufacturing its emission reduction device (ERD-4.0) for the transportation industry and the electrical power generation plant (ERD 1.0) used in combination with cryptocurrency self-mining. The Company’s segment includes Hydrogen energy for emission reduction, and Hydrogen energy-based cryptocurrency self-mining. The ERD 4.0 is engineered to operate in a modular format for greater efficiency. The ERD-4.0 is designed for installation on all vehicles with an internal combustion engine (ICE). The compact, self-contained ERD-4.0 includes a modular multiple-cell Electrolyser (creates electrolysis) unit for an internal combustion engine that can be retrofitted to any type of ICE to enhance the combustion process, independent of the fuel used (gasoline, diesel, ethanol or propane/natural gas). The ERD-4.0 system offers a programmable controller with fault detection.
