1.0 Introduction
This section of the paper will discuss mainly on the background research, aims and
objectives, research questions, outcomes and summary of this section.
1.1 Background of the study
Biomass is termed as a resource which is gathered by the burning of woods and various
other organic matters. Although the burning of fuels releases carbon dioxide emissions, the
utilization of biomass is termed as renewable resource. The utilization of renewable resources
has been adopted in various places in the United Kingdom as well. The utilization of biomass
can be adopted for converting into bio-energy which in turn will generate electricity (Marshall &
Thenkabail, 2015). This is termed as a renewable energy generation. These types of energy are
also used in place of other conventional energy sources. The utilization of the biomass resource
can also be used to generate heat for various reasons and can also be used in the form of bio-fuel.
The constituents of plant based biomass are the lignin or cellulose while wastage and animal
wastes can also be used for obtaining energy from it.
It has been stated that 50 percent of the power generated in the United Kingdom comes
from various amounts of low-carbon based sources. Although the utilization of biomass
resources for burning processes leads to the formation of a large amount of gaseous emissions,
the government of UK thinks of it as a renewable source of energy (Tilly et al., 2016). A major
power station of the United Kingdom has switched their requirements from the utilization of coal
to biomass. Many other power station of The United Kingdom has reinstated their business
operations from the utilization of coal based power plant to biomass based.

2.0 Literature review
This section of the paper is concerned with the discussion of the associated literature
which is related to the topic. The various aspects to be considered for this research is also
depicted in this section of the paper.
2.1 Crops
For the utilization of biomass energy from the plant based resources, the adoption of
energy crops are a pre-requisite. There are three different types of energy crops which are
broadly adopted for the type of resources obtained from them. The first type of crop is the
agricultural energy crops which include oil crops, sugar crops and starch crops (Kross et al.,
2015). These comprises of wheat, barley, oat, potato and sugar beet. The second type of crop is
the non-weedy crops which mainly includes hemp and rye. The third type of crop is the short
rotation based energy crops which consists of eucalyptus, sycamore and poplar.

There are many other types of crops which are grown in the United Kingdom but these
crops are considered mainly due to their energy harvesting capabilities. These crops can remain
in situ conservation for a range of 7 to 25 years. In addition, these crops have much deeper
rooting characteristics. Moreover, their growth rate is very rapid which in turn produces much
high amount of yield (Bendig et al., 2015). Furthermore, the fertilizer input and the pesticide
input is also very low which helps in better productivity of the crops. The harvesting of these
crops takes place in the winter season and in the early spring season. These crops are also
supposed to reach greater heights and form dense plantations.
For the research involved in this paper, the utilization of five different crops is required.
These five crops are wheat, barley, oat, potato and sugar beet. These crops will be collected and
the biomass content will be calculated. These crops will be stored in plastic bags which can be
re-sealed whenever required (Dong et al., 2016). These will then be kept in a cool condition and
the weighing of the crops will be done which will then be dried. If the sample plant is not being
weighed for measuring fresh weights, they will be transported in wet ice and will be weighed
within the next 24 hours.
2.2 Biomass estimation
There are various methods which can be utilized in the context of estimating biomass
content of crops. These are mainly used to find out the amount of resources that can be obtained
for obtaining the necessary requirements. The vegetation will be measured by considering the
quadrate frame of measurement. In this case, the delineation of the areas are required using the

UNITED KINGDOMS
help of these types of frames (Ledo et al., 2018). The measurement of multiple areas from such
quadrates is to be considered which will help in collecting the samples as required from the
whole plantation involved.
Although the need for calculating the biomass is a necessary consideration in case of any
plantation, the most common method of calculating the biomass is by using the harvest based
method. This involves removing the biomass and then drying it in the oven. This is used to
remove the water content from the plants involved which is then weighed. The water content of
plants can vary depending on the time of estimation (Fu et al., 2014). The water content varies
during the day and during the night. In addition, the seasonal basis is also responsible for
changing the water weight. This is the reason for drying the samples for collecting weights.
Another consideration to b adopted is the presence of the plants with respect to ground level.
For considering the biomass concentration, some plants have higher density above the
ground level while some others have low density in that region (Eitel et al., 2014). For various
processes involved in researches, the utilization of above ground measurements are more
preferred than the below ground measurements. This is mainly because there are various
problems associated in collecting information and data associated from below ground
measurements.
The use of various equations will be adopted for calculating the biomass of the crops
involved. With reference to the larger plantations, the calculation of biomass is based on the
various sections of them. These sections are mainly calculated by considering the stem, branch,
foliage and fruits (Jannoura et al., 2015). In each of the plantation involved, there are difference
calculation based metrics which are used for determining the biomass present.

Stem biomass=0.0478∗(DBH2∗H)0.8665
B ranch biomass=0.061∗(DBH2∗H)0.8905
Foliage biomass=0.2650∗(DBH2∗H)0.4701
Fruit biomass=0.0342∗(DBH2∗H )0.5779
In case of these above equations, the DBH is termed as the diameter of the breast height
which is used to denote the main diameter involved. The H symbol stands for height which
denotes the height of the concerned sample. Using these equations, the calculations of biomass is
made.

2.3 Biomass estimation from the crops
The estimation of the biomass and its assessment processes is comprised of two different
stages. The first stage is the power plant design stage and the other is the power plant re-

commissioning stage. The methods involved in both the stages of biomass estimation are same
but the objectives involved in them are totally different.
Estimating biomass at the power plant design stage:
In the power plant design stage, the method involves a detailed analysis and assessment
at the village level and the regional level. The regional level comprises of both the block and the
district involved. There are four main objectives of this design stage. The first objective is to
make a successful forecasting of its availability for considering its supply for a span of five
years. This step is followed by adopting the estimation of the pricings of the biomass resources
for the next five year period. The third objective is to apply for streamlining the process involved
which will help in providing biomass as a resource for the next time period of five years (Bendig
et al., 2014). The last step involved is validating the gasification technology which is based on
the use of biomass as a resource. This validation is considered in terms of calculating type of
technology to be used and the capacity of the storage services. For example, in case of a 30Kw
gasifier which is running daily for 10 hours, the calculation is done by considering the number of
days available. In case the number of days being 350, the total number of biomass to be
generated is 210 MT (30 * 10 * 350 * 2= 2, 10,000 Kg= 210 MT).
Estimating biomass at the power plant re-commissioning stage:
In this stage of re-commissioning power plant, the analysis and evaluation of the biomass
content is considered. This is done by considering both the level of villages and regional aspects
so that an effective evaluation can be carried out. These evaluations are done on a detailed basis
such that all the objectives and steps involved are met. The first step involved is to estimate the
availability of the supply of biomass based resources. The next step is similar to the above
