Modeling and analysis of Wind Hydrogen energy system

Abstract

Wind-hydrogen energy system is one of the promising energy alternatives for the future which enhances wind energy utilization. Wind energy is the most attractive source of electricity for distributed hydrogen production because the cost of wind-generated electricity is becoming competitive. Hydrogen can be produced from solar and wind energy by using electrolysis and by directly splitting water using photo electrochemistry, photo biological organisms (and other pathways), and heat-driven chemical reaction cycles.

Ethiopian Wind data assessment

The title may look strange but for sure Ethiopian wind data is unique. First because it is recorded only five times a day (few missing values) second, there is no night time data third long term standard measurements are absent. Therefore if you are designing and simulating an energy system consisting of wind turbines, because of these errors in the wind data your model is invalid. The good news is this can be tackled , thanks to the brilliant method developed by Dr Getachew Bekele, [see below].

Potential Bioenergy Options In Developed and Developing countries

In the EU15, agriculture occupies 40% of the total land area and nearly 30% of the continent land is covered with forest. Future potential of organic waste Organic wastes, wood industry residues, agricultural; and food processing residues, manure is 100Mtoe in 2010. The total biomass energy potential in North America is 19.9EJ/annum.This clearly shows

Circulating fluidized bed design,Part Three, Design Procedures

Design procedures

Calculate Minimum fluidization velocity: (could be calculated with the software as well)

Calculate Terminal velocity of the particle

Circulating fluidized bed design, Part Two, Ergun visual CFB

Methodology

In this exercise a 40MW soft wood fired CFB unit is designed. Calculation of important parameters are done using Ergun Visual CFB and also manually.

Ergun visual CFB

It consists of items important for design of CFB as shown in the diagram below. Data are fed to each item in the menu to calculate parameters like Umf, Ut, pressure drop and so on.
