CCS (carbon capture and sequestration) and CCUS (Carbon capture, utilization, and storage) technologies are essentially “after thought” to fix the CO2 emission by 2050. It also indirectly encourages continuity of fossil fuel usage for a foreseeable future to help those industries who have invested billions of dollars in creating their infrastructures such as “fracking”. Fracking generates hundreds of cubic meters of toxic effluent whose salinity is more than ten times that of the salinity of seawater. It is an environmental nightmare. Are these technologies practicable? Will they pay $100 or more for a ton of CO2 to capture and then transport hundreds of kms distance to find a suitable site; and even if they pay what will be the cost implications? Certainly, their cost of production will sharply increase, which will be necessarily passed on to the consumers whether it is a power industry or oil and gas industry. Why some of the CCS projects are dormant in many parts of the world? They claim injecting CO2 into existing oil field will increase oil production. Is there an evidence to substantiate such claims? But how many such oil fields exist in Australia, for example? The same question should be raised for all the countries around the world especially those oil importing countries like India, for example. IEA should publish necessary data to back up they claim that CCS and CCUS will lead to zero emission by 2050. In the absence of such data and hard evidence and the cost and economic analysis these projects will lead us nowhere? Without imposing Carbon tax as a financial incentive (not as a penalty) will these industries embark upon such a venture? The Carbon tax cannot be less than $250/Mt (because Carbon capture from air, for example, cost more than $150 to 200/Mt depending upon the maturity of technology). Now they want to utilize capture Carbon to produce synthetic fuel with green Hydrogen. Green hydrogen is awfully expensive, renewable energy is costly and storing them is prohibitively costly and converting them to Hydrogen by electrolysis is even more expensive. Despite all these expensive measures can zero emission be achieved by 2050. The cost of green fuel will be 10 times more than fossil fuels currently used. Will consumers afford to pay for such high fuel cos? Many questions remain unanswered. The word “Carbon capture” implies continuity of fossil fuel. It is like tobacco industry. At least in cigarette packs there is a warning ” smoking is injuries to health” but there is no such warnings in CCS or CCUS because the “captured CO2 will be released into atmosphere slowly at the point of usage in the near future , for example, Urea made out of captured CO2 will slowly release CO2 back into atmosphere by soli enzymes. Conversion to “concrete” or “nano Carbon” are claimed to be potential products but only future can tell. We are talking about “billions of tons of CO2”. Only carbon recycling and circular economy will be the answer and not CCS or CCUS.
‘Clean Energy and Water Technologies’ is now a social enterprise based in Melbourne, Australia. The purpose of this enterprise is to introduce a zero emission technology developed and patented by Ahilan Raman, the inventor of the technology. A 25 Mw demonstration plant will be installed to show case the above technology. This platform also used as a blog will publish articles relevant to Zero emission technologies for power and Zero liquid discharge technologies for water industries.

New realities of decarbonizing fossil economy and the science of climate change
Global warming and
climate change are the topics of the day and doomsday predictions are
abounding. In a divided world of differing ideologies and dogmas, emotions play
a major role and all conclusions are drawn out of such emotions. Emotional
intelligence is the key and in-depth analysis will clear the clouds of doubts
and disbeliefs and not just raw emotions.
When quantum science emerged as a mainstream
science substituting classical science the world changed dramatically often
leading to spirituality or eastern philosophy of ancient India. When Albert
Einstein said, “I hope the moon is still there when I am not looking at it”, it
had huge implications and a few decades later quantum science confirmed that
Einstein was wrong. In other words, it is the conscience
that creates the reality. With this is the reality of science one may wonder whether “reality” has anything
to do with “science” at all. Albert Einstein in his own words said, “As far as
the laws of mathematics refer to reality, they are not certain; as far as they are
certain they do not refer to reality”.
Let us examine about the
science of global warming due to man-made GHG emissions resulting in climate
change. Electricity was a new form of energy discovered in eighteenth century
and it became part of human civilization ever since. But it was already existed
in nature in the form of lightning, but we were unable to recognize it or reproduce
it in the scale that can be useful to us. Then the question is whether
electricity was discovered by human beings at all and if so, can we reproduce
“lightning?” and use this electricity without emitting any carbon emission at
all. The answer is no, at least for now due lack of technology to predict
lightning, tapping it economically and storing it for distribution.
Theoretically lightning alone can supply all the electricity world needs but
practically it is almost impossible to utilize it for the above reasons. When
electromagnetism and electricity were discovered they did not relate it to
“lightning” but claimed as a separate discovery between the relationship
between magnetic and electric charges which resulted in generating electricity.
Then later we were able to explain “lightning” due to positive and negative
charges between the cold clouds and rising hot air with water.
Science is nothing but
explaining nature with theoretical concepts and physical demonstrations. That
is why yoga sutra describes the world as a phenomenal world and it is an
irreducible experimental substance. That is the peculiarity of science because
it is the human conscience that creates this scientific reality. I too conclude
that “as far as law of science of climate change refers to reality, they are
not certain; as far as they are certain they do not refer to reality.” Similarly,
science has nothing to do with economics and but we human beings made economics
as a measure of one’s life and his or her success. This is the fundamental flaw
in human thinking. One can conclude that all man-made theories and practices
are fundamentally flawed which is evident from the world of turmoil we are
witnessing and living in. We failed to ask emotionally intelligent questions by
endless pursuit of happiness through money and materials in the name of
science.
As I mentioned in my
previous article we developed generating electricity from thermal source and we
ended up digging fossil fuels at enormous cost and added further value by
combustion with air generating huge amount of CO2.But we never estimated the
cost of CO2 at that time and we never realized the future impact of such a CO2
emissions from fossil fuels till now. Even now we do not want to put a price
for CO2 emissions and continue to emit by simply denying the fact that such
unabated emissions will have consequences. We conveniently use science and
economics when it suits us, otherwise we reject them outright when it does not
suit us. All climate change denials come from the fear of economic collapse
unconsciously.
Therefore, the first step
in achieving zero carbon emission is to eliminate fossil fuels completely or
impose penalty to discourage emissions if we accept global warming and climate
change as the reality. Without taking this first step we cannot move
forward.
Now there is a new
awakening that Hydrogen will substitute fossil fuels with zero emissions. This
is again a mistake. Imaging all cars and power plants using hydrogen and fuel
cell and emit (only) water vapour into the atmosphere. I am sure that will
drastically change our climate in a very short span of time. The atmospheric
moisture will dramatically increase trapping enormous amount of heat and
precipitation. The consequences will be dire. Every kg of Hydrogen will require
9 kgs of water. Renewable Hydrogen is a precious commodity and it can be
used only to decarbonize the fossil economy and cannot be used a fuel directly.
Such an attempt will be a failure.
Alternatively, we can
continue to use fossil fuel as usual but eliminate CO2 emission by simply
recycling in the form of RNG (renewable natural gas) using renewable hydrogen.
This may look as an expensive proposal at the first instance, but it will
become a norm in the long run and we human beings have a capacity to adopt to
this new reality. It is now possible to
capture CO2 economically and substantially while generating power using direct
Carbon fuel cell with highest electrical efficiency. It can be easily recycled
in the form of RNG. Why Governments don’t act?
In the absence of above alternative,
we may have to face the consequences of climate change due to man-made
emissions and simply be content with an American slogan, “In God we
trust”.
