‘Clean Energy and Water Technologies’ is now a social enterprise based in Melbourne, Australia. The purpose of this enterprise is to introduce zero-emission technologies and zero-discharge. technologies for seawater desalination plants. This blog will publish articles relevant to zero-emission technologies for power generation and zero-liquid-discharge technologies for the water industry. Both the above pollutions are responsible for the warming globe and climate change.

How to eliminate CO2 emissions from power plants and the discharge of highly Saline brine from the desalination plant to avoid climate change?
Why is decarbonizing the steel industry challenging, and what is the solution? Let me explain in simple terms. Iron ore in the form of Oxides, Fe2O3 and FeO, requires splitting, similar to H2O. It can be divided, like H2O, into H2 and O2 using electrolysis, which is increasingly becoming a solution to decarbonize. Fe2O3 can also be split into Fe and O2 using an electrolytic process. That is probably the next innovative solution to decarbonize the steel industry. However, it will require massive amounts of electricity, which must be generated again, to achieve Carbon neutrality. It is a vicious cycle; the only solution is to create a base load electricity with zero Carbon emissions, so that clean electricity can be used in steel production, to introduce Electric Vehicles, and even to generate Hydrogen on a 24/7 basis, without depending entirely on renewable energy or emitting CO2 into the atmosphere.
That is why, in CEWT, our total focus is on reducing CO2 emissions by converting Carbon emissions into a Hydrocarbon molecule through gasification, introducing a water molecule. Water and Energy are two sides of the same coin. Finally, no decarbonization is possible without water.
CEWT's technology utilizes closed-cycle oxy-combustion of R-LNG to generate a base-load power. A part of CO2 is recycled into the gas turbine, thus reducing the CO2 emission and the CO capturing cost and storage under pressure. The same R-LNG is subject to reformation in an SMR using our proprietary process to generate hydrogen-rich syngas. In addition to the captured CO2, the hydrogen-rich is subject to methanation, converting into synthetic methane gas SMG. The resulting SMG is recycled to the gas turbine, substituting R-LNG, thereby closing the cycle. It is a perfect example of a circular economy. The result is that no more fresh fossil fuel is required to generate a base-load power (24/7) while achieving zero CO2 emissions. It means there are no emissions and no requirement for fossil fuels. With increasing demand for base load electricity, while there is a serious threat of global warming and climate change due to CO2 emissions, CRT is the only hope to avoid catastrophic climate change.
We can use CRT for any CO2 emissions process, such as steel production using blast furnaces, base-load electricity, cement production plants, Aluminum production, glass manufacturing, caustic soda, and soda ash production.
CEWT offers a proprietary desalination technology that generates Sodium chloride brine directly from seawater as a by-product of desalination, with a 65% recovery of potable water. CEWT offers a distinctive solution to address the challenges of climate change, which is exacerbated by CO2 emissions and the discharge of highly saline brine into the ocean.
