Contributions were made to the performance improvements of the Injera baking stove. A
strong understanding of heat transfer modes was established and used to evaluate design
enhancements, aided by software applications ...
Smallholder farmers in Ethiopia face significant postharvest losses, particularly with perishable
products like onions. Solar dryers offer a promising solution, though their adoption is still early.
This research designs, ...
Nowadays, the need to replace nonrenewable fuels with renewable fuels such as bioethanol produced from lignocellulose biomass has gained attention. This study aims to convert cornstalk biomass into bioethanol via a biochemical ...
Coal, natural gas, and crude oil are major sources of energy. But they are nonrenewable
and continuously pollute the environment. Using renewable energy resources such as
biogas is one solution to address these issues. ...
Biogas is a green energy which can subsidize the energy constraint in one’s country. Biogas production using digesters plants in Ethiopia relay on single substrate and without fermentative microbe inoculation. These and ...
Through experimental tests and simulation, this work examined the drying characteristics, and
performance of forced convection Solar Bubble parboiled rice dryer. For the drying
characterizations and ...
Cement manufacturing is one of the most energy intensive processes and is accountable
for substantial pollutant emissions. Increasing energy costs forces Cement manufactures
and researchers to search for alternative ...
Rural electrification is the process of bringing electricity supply to rural and remote areas.
In this research an off –grid hybrid solar PV, wind turbine and diesel generator design
system was done to provide ...
Biogas is a renewable energy that is produced from organic waste. To enhance the calorific value
and better employ the biogas and eliminate undesirable parts from the raw biogas, it is important to
upgrade biogas by ...

The effect of microwave-assisted alkaline (MWA)pretreatments and acid hydrolysis of
lignocellulosic Wheat Straw were investigated. Pretreatment is a major step for the
efficient and effective ...
As described in Chapter 1, hydrokinetic technology has attracted a lot of interest as a
sustainable energy generation alternative, especially in places where conventional hydropower
technology ...
This thesis deals with the study of existing energy utilization and the integration of solar
photovoltaics into an existing diesel grid-connected hybrid system to improve the
reliability of continuous power ...

. Solar thermal process heating systems are a promising renewable
fuel replacement ...
The purpose of this study was to contribute to the advancement and development of
hydrokinetic turbines (HKTs), with a particular focus on vertical axis hydrokinetic
turbines (VAHKTs). HKTs are a comparably new energy ...
Doping is an alternative strategy for the alteration of as-prepared nanomaterial’s to
enhance their optical, structural, and electrical and electrochemical properties of
electrode materials. In ...
Hydrochar is a solid product of hydrothermal carbonization (HTC) of
organic materials. HTC is suitable for converting wet feedstock. Water hyacinth (WH), the
aquatic and hence wet plant, is becoming overwhelming ...
Energy is a critical requirement for economic development and specifically to improve
living conditions. It is one of the basic inputs in everyday life of human beings.
Geothermal Energy is one of the renewable energy ...
The production of reducing sugar is the most crucial process in the production of
cellulosic ethanol and can be divided into two steps. First, pretreatment removes the
unwanted constituents of lignocellulose to ...
