The real solution for Carbon problem:
When mother nature buried Carbon under the ground by way of fossil, we human beings mined them at enormous cost and added further value by combustion with air converting it into CO2 (carbon dioxide). In fact, we human beings added enormous value to carbon that remained buried (with zero value) for millennia. We were interested in the heat of combustion but forgotten about the CO2 emission. This is the fundamental flaw in the commercialization of thermal power using fossil fuels. Now there is a price to pay. There are only 2 options to overcome this problem.
1 We can completely ignore and ban fossil fuel all together at enormous cost (we have already invested in trillions in mining, processing, transporting and storing) and seek completely a new solution without any Carbon at all. This is unlikely to happen.
2 We can continue to use fossil fuel and generate base load power as we have been doing for decades but capture CO2 and convert it back into fuel so that it can be recycled with Zero CO2 emission. This is certainly feasible.
Many “so called innovators” are suggesting alternatives to fossil power generation using renewable source of energy. These sources were available with us from the beginning of the world as we know it, but they are intermittent. We are used to 24
The real solution lies in using intermittent renewable energy to generate base load power (24 x 7) with zero Carbon emission. Renewable Hydrogen can achieve this goal. In doing so battery can also play a small role but not a major role. Couple of things should happen to achieve this goal.
1. Capturing CO2 at the lowest cost. It can be best achieved using Oxy combustion of fossil fuel such as LNG (because it is a purified form of natural gas) using Brayton cycle with 100 % CO2 capture.
2. Generate renewable Hydrogen (RH) using electrolysis using renewable energy source such as solar and wind etc. Technology is well proven and commercially available.
3. Convert captured CO2 into CH4 using methanation reaction (which is already commercially practised) and recycling CH4 as a fuel to continue the base load power generation as usual. The newly generated CH4 becomes a renewable natural gas (RNG) by substituting fossil Hydrogen with renewable Hydrogen (RH). This technology developed by CEWT is known as Carbon Recycling Technology (CRT). It is a perfect example of a circular economy. Governments around the world should scrap fossil subsidies, tax Carbon @ $100.Mt ( at least) and offer liberal subsidies to renewable energy so that the cost of renewable hydrogen (RH) is at the lowest. CRT will allow Carbon to remain below ground as nature has done for several years. CRT will allow to run base load power (24 x 7) using RNG with ZERO CARBON EMISSION.
The above process is the only economical, commercial and environmental solution to the problem of global warming and climate change. All other methods will be expensive, time consuming with no guaranteed results and are unlikely to happen in the shortest time we have.
We at CEWT have the solution (not just theoretical but practically and commercially implementable immediately) and we seek like-minded partners and investors to team up with us so that we can show case the technology and implement them worldwide.
