Ramana Power Cycle (RPC)
RPC is a newly developed patent (pending) technology from Australia to generate a base load power (24x7) using Renewable Hydrogen and CO2 with Zero emission,
The process discloses a method and system to generate CO2 from seawater along with Hydrogen using any renewable energy source to produce synthetic methane gas known as renewable synthetic methane (RSMG) to generate a base load power. The CO2 can be from various sources apart from sea such as power plants using fossil fuel, steel, cement, coke oven gas, or any syngas generated from various known methods from various sources such as steam methane reformer etc. The process can use any Oxy-combustion CO2 power cycle such as CES, Graz cycle, Allam cycle (using super critical CO2 as a working fluid) or a conventional combined cycle power plant using air combustion to generate a base load power 24 x 7 with ZERO EMISSIONS. The cost of power is estimated to be competitive even in the absence of Carbon pricing or Carbon tax. Needless to mention the unit cost of power can be further reduced by using Carbon pricing or Carbon tax. It is up to individual governments to introduce such a mechanism in order to deploy RPC on a larger scale.
The advantage with the system is it can generate electric power from CO2 with the highest electrical efficiency up to 70% while achieving Zero emissions. It effectively solves the global warming and climate changes problems using existing technologies and infrastructure without a need to develop a new power technology from scratch.
It can be retrofitted with any existing and operating fossil fuel-based power plant OR any large-scale renewable energy plant. It does not require storage batteries or any energy storing devices. The minimum viable capacity starts with 100 Mw and can be scaled up to 500 Mw and beyond and power can be exported to the grid directly through a substation. Optionally the process requires only sun and sea (ocean is the largest reservoir of Carbon, Hydrogen and heat to generate a base load power along with potable water with Zero Carbon emission and achieves circular economy).
