WATER AND ENERGY ARE TWO SIDES OF THE SAME COIN

 




I always believed one can create energy from water and water from energy. Ancient Hindus believed water comes from fire and fire comes from water, two fundamental building blocks out of five elements that are necessary for Creation.

Water (H2O) is made up of two atoms of Hydrogen and one atom of Oxygen. The structure itself is an absolute beauty because it contains both reductant and oxidant tied up inseparably in such a way it requires enormous energy to separate them. Individually Hydrogen forms an explosive mixture with air on combustion. People familiar with Oxy Hydrogen will know such a stoichiometric mixture of Hydrogen and Oxygen in gaseous form by water electrolysis generate a flame that can cut an iron piece but leaves water on condensation. Current methods of Electrolysis using PEM (proton exchange membrane) can not only split water into Hydrogen and Oxygen but also separates them simultaneously into two different gases. Fuel cell just reverses the above reaction by combining Hydrogen and Oxygen generating electrical power and heat as a by-product. The fundamental facts about water and energy remain the same for millennia.

We are now facing a new challenge of global warming and climate change that is supposed to be caused by the unabated emission of CO2 into the atmosphere by the combustion of fossil fuels. The world is now gearing up to achieve net-zero emission by 2050. In my opinion, it is not such a big challenge, but the world has neglected emissions for too long. The science of electricity generation using electromagnetism is far from perfect in the sense it failed to consider the emissions by combustion of fossil fuels. The simple solution is to reduce the oxides of Carbon back into Carbon so that there will be zero-emission. Unfortunately, we never used pure Oxygen for combustion but air because it is readily available and cheap to use. But it generates not only CO2 but also NOx, NO2, H2S, SO2, etc. all contributing to air pollution which is now affecting the world by way of global warming and climate change. The CO2 level in the atmosphere has now reached 415 ppm which is only part of the anthropogenic CO2 emission since the industrial revolution. About a third of it has been absorbed by the ocean thus acidifying the seawater. The pH level of the sea is slowly but steadily decreasing making it more acidic. Thanks to the enormous buffering capacity of the sea and such a change are hardly noticeable. But it will soon change the chemistry of the water. It is a complex situation with the changing chemistry of seawater due to absorption of CO2, heat, increasing salinity. Sea levels rise due to melting of glaciers, constant discharge of highly concentrated effluent discharges from seawater desalination plants and power plant cooling towers, etc.  Climate modeling in the future will be challenging.

I previously posted an article on “Zero-emission baseload power using only sun and sea”. It has attracted many viewers worldwide especially in my blog/: https://www.clean-energy-water-tech.com.

I have already filed a provisional patent application with IP Australia, and I am in the process of filing an international patent application so that I can secure an IP with a value. The technology is based on a couple of well-proven concepts and it will not be difficult to implement them commercially. A couple of multinational companies has already endorsed my process they are even willing to take part as EPC (engineering, procurement, and construction) contractors.

I am planning to seek donations and contributions from my worldwide audience by way of crowdfunding to secure an IP worldwide so that I can practically contribute my knowledge and experience to address one of the greatest challenges of global warming and climate change.

Please watch this blog and my next article will elaborate on my patented technology.

 CARBON RECYCLING TECHNOLOGY (CRT) also known as RAMANA POWER CYCLE (RPC) FOR A ZERO EMISSION BASELOAD POWER USING ONLY SUN AND SEA.

I invite everyone to contribute by way of donations to my campaign at

  https://readyfundgo.com/?post_type=ignition_product&p=52427.

The funds will be used to seek international patent for my invention as an intellectual property. It will enable me to demonstrate further the invention by installing a 25 Mw baseload power plant with zero emissions using only sun and sea. It is a small beginning for a lasting solution for a net zero emission technology. It will also help reduce ocean acidification and help marine life including corals. It will be the new beginning !

Renewable synthetic methane gas (RSMG) and Ramana Power Cycle (RPC) for Zero emission base load power.


RSMG is an abbreviation for ‘Renewable synthetic methane gas’ and it is a new form of a Carbon negative synthetic fuel to substitute natural gas. It is synthesized using  CO2 extracted from the sea or from power plant using Oxy combustion CO2 power cycle at the site such as CES, Graz cycle or Allam cycle (using supercritical CO2 as working fluid)  and Renewable Hydrogen (RH) by the following reactions using a renewable energy source.
1.    CO2=> CO + ½ O2 (electro-chemical reduction)
2.    CO + 3 H2=> CH4 + H2O (catalytic conversion)
There are other methods too can be applied but our patented process uses a unique method to synthesize RSMG from CO2 and renewable Hydrogen with a heating value (LHV) around 52 Mj/kg.
By using only, the sun and sea water, RSMG is continuously synthesized using continuous renewable energy such as OTE (ocean thermal energy) on 24 x 7 basis. Ocean is the largest reservoir for clean drinking water, Carbon dioxide, Hydrogen and thermal energy and it is imperative that the absorbed CO2 is extracted along with  stored thermal energy in order to restore the warming ocean to pre-industrial state to mitigate climate change. The success of the system depends on the availability of the lowest cost of renewable energy on 24 x7 basis such as Hydro or OTEC. Alternatively, the cost of renewable energy should be less than a $0.05/kwh.
What is RSMG?
RSMG is like natural gas with higher heating value consisting of pure methane and Hydrogen with no other impurities such as sulfur compounds or CO2. It is synthesized using a proprietary technology using CO2 extracted from seawater and renewable hydrogen (RH) using a renewable energy sources such as OTEC or Solar/wind etc. It can be compressed like CNG or liquified like LNG and can be transported or shipped to various destinations. RSMG is a Carbon negative fuel because it uses already absorbed CO2 from the sea and not from burning fossil fuel and it is also renewable because the O2 from CO2 emission is substituted with renewable Hydrogen (RH) constituting synthetic CH4. The purpose of this technology is to recycle Carbon indefinitely at the site of usage and that is why transportation in the form of CNG or LNG is discouraged.

Ramana Power Cycle (RPC)
RPC is a new patent (pending) technology to generate a base load power 24 x7 using a renewable synthetic methane gas (RSMG) with Zero emission. By constantly recycling CO2 in the form of RSMG during Oxy combustion CO2 power cycle we can eliminate usage of fossil fuel completely. Moreover, there will be no need to extract further CO2 from seawater for a specific power plant because Carbon is being recycled constantly. Only further RH will be required to run the base load power plant.
How RPC works?
RPC uses an Oxy combustion power cycle such as CES, Graz cycle or Allam cycle (using super critical CO2 as a working fluid) to generate a base load 24 x7 power. It uses 80% of CO2 generated internally leaving 20% high purity pipeline grade CO2 which is used to synthesize RSMG at site for recycling. That is why RSMG is renewable. Thus, RPC continues to generate a base load power with Zero emission. The electric efficiency of RPC is nearly 70 % and the cost of power is competitive to any other power source. By continuously generating RSMG and recycling CO2 it achieves Zero emission without any requirement of fossil fuel such as natural gas. Thus, the process can decarbonize the fossil fuel industry completely at the fastest time frame. Using 100% renewable hydrogen (RH) in gas turbine is still a long way off to achieve a commercial reality. Currently only up to 30% RH has been tested along natural gas (30:70) and there are several technical problems to be solved with combustor. Moreover, the maximum efficiency in Hydrogen based gas turbine will not exceed 35% at the maximum.

How RPC is different from Allam cycle, for example?
Allam cycle has been selected by IEA (International energy agency) as the most efficient (electric efficiency at 55.4%) Oxy combustion power cycle to generate a base load power using natural gas. It generates 20% pipeline grade CO2 as by-product suitable for CCS applications. It requires natural gas as a fuel. It generates pure Oxygen from air using ASU (air separation unit) by cryogenic process. Air separation is an energy intensive process consuming as much as 15% generated power internally thereby reducing overall electric efficiency of the system. Moreover 20% CO2 discharged from the plant requires long distance piping and sequestration both are expensive thus increasing the cost of power.
RPC uses pure Oxygen generated as by-product of renewable hydrogen (RH) by electrolysis for Oxy combustion of RSMG and to continue to generate a base load power at highest electrical efficiency at competitive rate. Synthesis of RSMG is highly exothermic chemical reaction which generates superheated steam as a by-product which generates additional power using steam turbine thus enhancing the overall electric efficiency of RPC.
RPC is suitable only for large power generation such as 100 Mw and above. The process requires the cheapest and continuous renewable energy source such as OTEC, offshore wind turbines supplemented by PV solar. The main advantage of the system is it does not require large scale energy storage and the base load power can be exported directly to the grid using a substation as it has been done over several decades.
RPC has the potential to decarbonize the fossil economy at the fastest rate than any other methods currently used.
Any power generation technology should be able to meet the following seven criteria in order to be successful.
1.Power availability.
2.Power dispatchability.
3.Zero emissions.
4.Lowest levelized cost of power
5.Potential to decarbonize the fossil economy at the shortest time frame.
6.Potential to Completely eliminate fossil fuel
7. Sustainable and has a potential to achieve circular economy.
RPC can meet all the above seven criteria.
