It is time to tax Carbon emissions


There is a growing concern among the nations in the world about the changing climate due to greenhouse gas emissions (GHG) and the natural disasters associated with them such as loss of human lives and billions of dollars’ worth of damages in assets. Yet there is no political will or consensus among the largest emitters of CO2 on Carbon emissions at the peril of their own economy and the rest of the world. Paris agreement remains on paper, but largest emitters are either moving away from such an agreement or they continue to emit CO2 without any regard to their agreement. Unfortunately, such a situation has risen due to a scepticism among the public and politicians about the relationship between greenhouse gas emissions and climate change. They believe science has failed to establish a clear evidence between GHG emissions and climate change. Secondly there is a fear among the public and politicians that complete elimination of CO2 will be a prohibitively expensive exercise and such expenses will be eventually passed on to the consumer and such a move will make the governments in power unpopular and it is a risk and they may lose their future elections as a government. Some countries such as US, Australia and many EU countries believe elimination of CO2 completely will lead to job losses and lead to closure of industries such as automobiles, coal mines, steel plants, cement plants and make the government unpopular. All these notions are based on an erroneous belief that it is impossible to eliminate man made CO2 emissions from earth without compromising an economic growth or risking high energy bills. CO2 emissions can be eliminated by simply converting them back into a fuel using renewable Hydrogen. For example, CO2 emissions by using natural gas such as combined cycle or cogeneration/ trigeneration plants can be recovered and converted back into SNG using renewable Hydrogen so that natural gas can be substituted with SNG. Such substitution will spur the growth of renewable energy industries such as solar, wind, geothermal and biogas in a big time while fossil fuel industries can continue their operations with Zero Carbon emissions. But this will be practically possible only if renewable hydrogen industry is suitably rewarded while penalties are levied against CO2 emitters. The market will take care of the rest of the issues and government can stay away from the politics of Carbon and allow industries to address GHG emission problems. Currently the cost of recovering CO2 from polluting plants is about US$ 75/Mt and therefore Government should tax polluters at least at the rate of US$ 100/Mt and pass it on to renewable Hydrogen generators @ US$ 100 /Mt of CO2 eliminated as an incentive. It will lead to a healthy and robust industrial growth, large scale employment and guaranteed sustainability. It will completely eliminate the necessity to store energy. At the same time, it can also help create alternative energy technologies such as batteries and Fuel cell etc and eliminate CO2 emissions from transportation. Renewable Hydrogen can supply energy sustainably and there will be no need for mining coal or exploring oil and gas to manufacture Nitrogenous fertilizers. Petrochemical industries too can continue their operations without CO2 emissions. The only requirement will be to design a plant for a pre or post combustion CO2 recovery and Oxy-combustion technology for fossil fuels. #tax Carbon emissions # renewable Hydrogen # Zero Carbon emission Advertisements

Carbon Recycling Technology


CRT Carbon Recycling Technology known as “Ramana Cycle” is a new patented concept and system that addresses current problems faced by energy industries with a single solution Current problems: 1.Renewable energy is only a fraction of total energy generated world-wide. Fossil fuel especially natural gas in the cleanest and most widely accepted fuel for base load power generation. However, it emits CO2 a greenhouse gas causing climate change. 2. Electric and Fuel cell cars can eliminate Carbon emission from our roads, but it will dramatically increase the electricity requirement which cannot be met by renewable energy sources alone. Eventually the electricity demand will have to be met by fossil fuels which will sharply increase CO2 emissions in a short span of time thus exacerbating global warming. 3.Grid connected renewable energy has many problems due to intermittent nature of renewable energy such as synchronicity, electronic interface with HT lines, metering etc. There is at least 22% loss while transmitting renewable energy into the grid creating dispatchability issues. Power is transmitted 24 x 7 on HT lines. Solution: CRT addresses all the above issue with a single solution as described below. CRT synthesizes a synthetic fuel CH4, a Hydrocarbon known as SNG (synthetic natural gas) using Carbon from CO2 emissions of gas based power plants and renewable Hydrogen generated from water using renewable energy sources such as Hydro/solar/wind /biomass/ geothermal etc. Once SNG is generated then it can substitute natural gas currently used in power generation. It means one can generate their own SNG and need not depend on oil and gas industries and use conventional gas turbine and generate base load power and transmit using existing transmission lines. This power can be used by electric as well by Fuel cars. There will be a net Zero Carbon emission.The same system can also supply Hydrogen to Fuel cell cars. CRT can be implemented using existing systems supplied by internationally known companies with proven technologies and systems. There are absolutely no commercial risks whatsoever. These systems can be deployed immediately, and they are commercial ready. Each plant is designed specifically based on the capacity, location and purpose.
