Irreversible climate change and human failure !
Increasing ocean salinity, decreasing ocean pH, increasing CO2 concentration and water vapor in the atmosphere will irreversibly change the climate. All the above four parameters are directly attributed to human activity and they are inter-related. Warming ocean and increasing evaporation in some parts of the world, large scale (billions of m3/day) discharge of highly concentrated saline effluent from seawater desalination plants around the world, unabated emission of CO2 and water vapor by burning fossil fuels, ocean acidification by CO2 absorption are directly connected with human activities. NASA is monitoring seawater salinity and water vapor concentration in the atmosphere using special satellites while NOAA is monitoring ocean acidification and salinity of the oceans. They can only provide information and warnings but it is up to relevant government authorities to act. Failure to act will cost lives and the economy and the world is already witnessing them. Oil and gas companies are now using a new slogan (carbon capture and storage or sequestration and reuse) to prolong continuity of fossil fuels. “carbon capture” guarantees continuity of “Carbon emissions”. The real solution is to “decarbonize our air and sea” and recycle Carbon internally in a closed system not “carbon capture or reuse and claim Carbon neutrality”. These projects will exacerbate climate change if we fail to decarbonize air and sea using renewable Hydrogen. An estimated 2000 billion tons of CO2 is already available in air and sea since the industrial revolution and there is no need for any fresh fossil fuel. We are facing “irreversible climate change and human failure to address them in a timely manner”. Bold leadership and political will while monitoring ‘misleading players’ and penalizing emitters by imposing Carbon tax will be the key.

RPC is a newly developed patent (pending) technology from Australia to generate a base load power (24 x 7) 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  gas (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 RSMG 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).
