Good morning everybody, and welcome to this course on bioenergy. I have already give you the introductory video about what the course will cover, but today we will slowly start to explore this wonderful world. So whenever we talk about energy, different kind of thoughts come in each one of us mind,
we think about oil, we think about electricity, we think about power stations, we think about filling fuels like petrol or gasoline or diesel into our cars or when you go to the kitchen we think about the cylinder gas,
cooking gas and all these things. They all are forms of energy, as a matter of fact, if we think over it, our whole civilization, our whole growth is a direct function of our energy consumption, as a matter of fact, it is being always said,
the development of a country, how developed it, is decided or the currency which is used for that is, how much per capita, energy consumption is there. Most developed societies of the world consume, way more energy as compared to the societies, which are not that well developed.
And that has a direct link to the economy of the world, and those which are you know, developed economies they consume way more energy. Those which are developing economies they consume less at lesser energy than the developed economies and those
which are underdeveloped economy has a scarcity of energy. So, our life, our day-to-day living, our national status, and our global standard and our global status with respect to other countries, is a direct function of energy. So, in this course, which is about bioenergy,
first of all, we will talk about the global energy landscape. So, and then in that global energy landscape where bioenergy stands and what is this by energy is all about because as you will go through different kind of monograms or different books, different lectures all over, there is every possibility that one may get confused because
there are several aspects of it and to give a holistic view is kind of bit challenging. So, in this course, my aim will be, to give my young readers
bit challenging. So, in this course, my aim will be, to give my young readers a very holistic view, a overall view and from that overall picture which so ever aspect of bioenergy in their life they wanted to pursue or even just wanted to get more and more knowledge into it.
They will have sufficient background so that they can proceed in that direction.
So it will be kind of a mapping the whole spectrum of bioenergy with respect to the global energy landscape, Okay. So in a way you can say, so let just start it.
So this is, what is our course title is and if you see this course title it has two parts and one part is this part which is the bio and the second part is this part which is the energy.
So, our initial talk will be on understanding how energy revolves around our life, okay. So
the core idea will be, once you kind of get an idea about the whole spectrum of bioenergy you can philosophize the whole subject. So, keeping that in mind, I have divided the course into five different segments. The first segment we will be talking about,
segment one or module one what you will see is about introduction to bioenergy.
So in the introduction to bioenergy, which is today is the first lecture of that, we will be covering, five lectures on it, on introduction and in those five lectures we will talk about the whole energy landscape and how in our day-to-day life energy plays a significant role,
followed by that we will move on to the module two, module two we will have basic biomass technology.
Which is essentially how in nature biomass is being produced which will include basic processes of photosynthesis and other route like chemosynthesis by which biomass is produced. And the part two will give you an overview of how these biomasses
are being transformed into different form of usable biomass, as a source of energy, having said this, we will move on to the third part of the course, where, we will be spending three weeks on it, on about different kind of biofuels which are being generated from this
different sources of biomass, okay. So, we talked about the biomass. Now, the course will move into three different fragments which are same, which is part three, which is biofuel
one, then we will go to part four which will be bio -fuel two and biofuel three. So, do not get confused the reason to give one to three is just to
biofuel three. So, do not get confused the reason to give one to three is just to classify them in different categories and kind of you know give you an overall picture of the different sources from with these different kind of biofuels are being developed. Followed by this, after the fifth section, we will move on to the sixth and the seventh section, which will essentially will be another route.
Where we will talk about the newer and newer technologies like bio power generation, one phase one and Phase two, so, in this section this is a section, where we will be investigating all the different kind of newer and newer technologies where different kind of
biomass or bio materials are being converted into different kind of charge storage devices, where the crop residues could be transformed into, say, supercapacitors or batteries to storage,
store charge or different kind of bio resources which may find, applications in solar cells, different kind of dyes, which may be used for harvesting solar energy at the very remote places. So,
places. So, such technologies, which are evolving technologies currently and which I believe that, will help you to broaden your horizon about the whole area of bioenergy will be covered in those sections which is numbered as sixth and seven. The last section, which is the bioenergy
induced distribution and economics. Okay. This is the last section which is who are the end-user and distribution, and of course, it will be linked to the economics of using bioenergy.
So, if you look at the course very carefully, you will realize, we have distributed the course in eight weeks. So, this is week one, what will be dealing with. This will be week two, five lectures, five lectures each and within the biofuels section week three, you have week four,
you have week five and then we have the bio power section, which will be week six, week seven and then we will be concluding on week eight.
So, what is important here is, if you have this map in your brain, this is how we are going to follow it to be very easy for you to know if you miss out any lecture or something you exactly know, where to dilate, and where to pick it up, and what I will do further, is once we will go to every week I will give you kind of an outline, how
say today's lecture is related to tomorrow's and likewise and so forth. So, you will have a mind map of all the forty lectures very clearly in your brain that what is the sequence, how I am trying to narrate the story of a very broad horizon called biomaterial bioenergy. Okay.
If you look around you will see, that how energy is involved in your life. We talked about, say air so, you needed to supply clean air, if you need clean air in any room or anywhere you need heavy duty pumps or HEPA filters or something to make the room clean,
say, for example, its operation theatre or in a very clean room for any kind of manufacturing.
We talk about water which is another resource. Okay, so let us kind of enumerate some of these things which will kind of give you an idea, how energy is really ruling our life. Okay,
So, say for example we talk about, like I will put three columns, which will kind of give you an idea. So say, for example, we talk about say air, these are the basic requirements,
an idea. So say, for example, we talk about say air, these are the basic requirements, basic needs of our life, then we talk about say, water okay, then of course food, then comes our shelter and then comes our clothing.
Now in order to have these things, so we need will always look for clean air we wanted drinking water then we will look for abundant food supply then we need eco-friendly shelters.
As you must be aware of government has promised that by 2020 each one of us will have their own home or housing then we need sustainable clothing.
For all these things, if you realize if you see the other side they all demand certain things in common. Now one of them for that we need clean pollution-free air that in requires energy in order to clean the air,
pollution-free air. Then water you need the purification that requires a lot of
pollution-free air. Then water you need the purification that requires a lot of energy input, so if you look at all the big water cleaning plants all over the world, in the cities in other places, if you kind of you know see they will be a place where all the water
is being collected and goes through a series of filtration assemblies which consumes a lot, lot and lot of energy to maintain over a period of time and that consumes a lot of electricity.
Then comes to the food if we talk about the food production in terms of the agriculture, we will talk a little bit more in our next slide on this thing. So those of you who are from village background and those of you are not you all are aware about that ammonia is being used for all the agricultural purposes, you will be surprised to know
that the amount of energy which is consumed for ammonia production is phenomenal and we will take this as a case study in our next slide. So before that let us finish this chart out here. Then we talk about the shelter, so we talked about the eco-friendly shelters
here. Then we talk about the shelter, so we talked about the eco-friendly shelters so then for that we need the construction materials which has to be developed. Okay,
and in terms of the clothing, you can we have the fiber production and these fibers could be natural as well as synthetic and if it is a natural fiber than we are talking about a form of biomass we will talk later on that and if it is synthetic then we are
transforming some certain things and this all demands a huge and amount of energy input.
So highlighting word is energy, so you may appreciate that for the bear requirements of our whole living, we are completely dependent on different kind of energy sources
and most of our energies are being provided by either by the fossil fuels or partly by solar very little though and these fossil fuels are used to produce electricity which runs our whole life, whether it is an air-conditioned room, whether in a very cold place you have to run a heater
or your other option is that you burn woods which is nothing but a biomass.
So, all our life is nothing but our energy economy. Now from here, I will take a very simple example to kind of give you an idea in our next slide. Okay, I told you that we will talk about a little bit about the agriculture, okay so let us move on to the
next slight where we will talk about. So, for the ammonia, so this is the molecule of ammonia NH3 okay this is the case study we are looking at, so ammonia is actually produced by
reacting hydrogen plus nitrogen okay, which is abundant okay by a process called Haber s process. And this Haber s process was developed more than a century ago in1905
process. And this Haber s process was developed more than a century ago in1905 now if you see this reaction, this reaction seems very simple I mean there is hardly anything which cannot be achieved in it, okay but here is the catch for this reaction. This reaction has an input of significant amount
of hydrogen and from where you obtained this hydrogen so, this hydrogen which is provided
by the natural gas which is why I steam reforming. There is a process called steam reforming. You can
go and check into all the Haber s process and all these things you will realize, so this steam processing so as a matter of fact, the largest in agriculture the largest consumer of fossil fuel in modern agriculture is ammonia production for fertilizer, of course via the Haber s process and this is of course we know that how essential it is for intensive agriculture.
And the specific fossil fuel input to fertilizer production is primarily the natural gas. And this natural gas is the one which helps in the production of the hydrogen and from here once this is produced these are put in a compressor, in the compressor from the compressor this is moved to a ammonia synthesis vessel.
And in the ammonia synthesis vessel this is a second source of energy expenditure, ammonia synthesis vessel has to be heated at 500 degree centigrade with a catalyst like iron, aluminum oxide, potassium oxide likewise.
So, these are the different catalyst which are used, from here the ammonia has to be removed.
You kind of kind of see that where all the energy is being used and then there is a cooling vessel which is involved here and this cooling chamber, this is re-circulated like this through a recirculation pump.
Now what I will do, I will highlight all those places, where energy is being consumed in order to run the recirculation pump, steam reforming and this is the third zone.
So, even it is it is most simplistic form if you look at the whole process, you will see, there are at least three different places where you have to consume significant amount of energy in order to produce the most or one of the very key fertilizer
for production of food. Now the question comes other way, if for one ammonia production which is a case study, we have to use that much fuel or that much energy has to be expended, so you needed that much amount of supply of natural gas or some other form which will produce that amount of steam reforming hydrogen,
steam reformed hydrogen, okay. Now if you look at it for any economy in the world wherever it is, you can classify, why I was telling this, let us say for example let us take the case study of India. If this is our, this box represent
India, okay, now we import oil, all of you are aware of, we are oil importer. Okay,
and in order to import oil, we have to use lot of our foreign exchange, foreign exchange spending. Now, in other words, this is what I was telling you
in the beginning, we are basically oil-derived energy making us a oil-dependent economy. And if we are on oil-dependent economy
oil-dependent economy. And if we are on oil-dependent economy it means either we should have sufficient oil for us or we import oil from other places where oil is produced in abundant, like Middle East, like in Latin America and all other places.
So what is the challenge? So, challenge is here, could, so it is coming back to the slide could we become from oil-dependent economy to be an oil-independent
economy and how we can become oil-independent economy and where lies our real hope, so, in today's lecture I will close in here with this question that how India from an oil-dependent
economy can become an oil- independent economy now having said this let us summarize what we talked today first we talked about that this course is aiming at giving you a overall picture of my energy with respect to the complete global
landscape of energy sources of energy okay. And consumption of energy then we discussed how a country is being position or it is triple position with respect to their energy consumption, if you are a high energy consumer, you fall underdeveloped countries, if you are a moderate energy consumer then you fall under developing countries and if you are
a low energy consumer then you fall below almost you can call it something like a poverty line or energy line. You can draw imaginary energy line if you're below that energy line of consumption then
energy line. You can draw imaginary energy line if you're below that energy line of consumption then you are really underdeveloped. Okay, then we talked about, how we have distributed this course in a way, so that this course will give you an overall picture so that at any point of your life you want to explore anything you exactly
know what is the map of all the developments which has happen and which are about to happen in next 50 years or so and then we talked about, how in your day-to-day life, whether it is a clean air, whether it is a water, whether it is a shelter, whether its food or whether it is clothing, how energy is directly involved in your day-to-day life okay.
And then we took a case study of ammonia, ammonia production by Haber s process and we showed you or rather we shared with each other that for such a simple molecule which is NH3 which is so very broadly used, the amount of energy which is being consumed. So that
from there we talked about we are energy-dependent economy and our rather the oil-dependent economy, how we can become an oil-dependent economy to an oil-independent economy could we really put our thrust on bioenergy production because that is where lies lot of our hope being a country which is not up
very close to the tropics and subtropics zone. Where there is abundant biomass production all over the nation, could we really make a difference in that area, so this is the overall spectrum, so apart from it what I will do all these lectures what you are seeing, what I am drawing in front of
you, I will scan some part of my own notes and I will just put them as PowerPoint for you people you can also go through them, okay. That will kind of give you an overall idea and I will send you all the references, which will also help you to refer to the right kind of books and
most importantly, it is a very important that through these small lectures you try to philosophize the subject it is very important because that is the most important thing.
It is not a informative thing, it is most important you should have a philosophical bent to realize that okay, what really needed to be done, do we address one of the most challenging question, could one day we become a oil-independent economy and we
should be so powerful enough that we should be able to you know give energy to others.
So with this, I will conclude my first lecture. In the second lecture, we will pick up the topic by looking at the global energy landscape where we stand and where lies the advantage of beings so uniquely positioned close to the equator and in a very
sub tropical zone where we really can have enormous biodiversity to support the cause, in which we are working towards called bioenergy okay. Thank you.
