Idem’s Clean Energy Research (ICLER)

Innovative Technologies for Generating Clean Energy


About Us

Welcome to ICLER

In his capacity as the Entropy Inc. Research Chair in Carbon Capture Technology, Dr. Idem is strategically poised to leverage his extensive background spanning over two decades in training engineers, researchers, and technical personnel. This expertise is centered on the intricate domains of design, development, deployment, and operation of clean energy generation systems. Driven by this wealth of experience, Dr. Idem is dedicated to facilitating Entropy’s ambitious objective of overhauling and de-carbonising its energy infrastructure to attain net-zero emissions.

Introducing Idem’s Clean Energy Research, (ICLER), a pioneering platform meticulously tailored to disseminating the profound research endeavors undertaken by Dr. Idem’s esteemed research group at the Idem’s Clean Energy Research, (ICLER), University of Regina. Our commitment is to deliver intellectually stimulating and enlightening content within the realm of clean energy. This is merely a preliminary glimpse into the wealth of knowledge we aim to provide.

Anticipate a comprehensive exploration of topics such as carbon capture and storage (CCS) within the context of fossil fuel-based power generation, CCS integration with biofuels, hybrid CCS systems encompassing both fossil fuels and biofuels, hydrogen energy, alternative energy paradigms, and a diverse array of innovative concepts and strategies aimed at achieving environmentally sustainable and cost-effective solutions.

Keep an eye out for forthcoming updates on our exciting new venture!

Storage and Utilization of CO2 in Ready-mix Concrete Using CO2-loaded Aqueous Inorganic Solvent

By: Benjamin Asare

Recently, there has been significant attention focused on utilizing captured CO2 to produce valuable materials. An example is sequestering CO2 through mineral carbonation and converting it into a commercially valuable product (Jang et al., 2016. Constr Build Mater, vol. 127, pp. 762–773, Elsevier Ltd).....

Using Catboost-SMOTE Machine Learning to Discover Brand New Amines which can be Synthesized and Tested for their CO2 Capture Performance

By: Pailin Muchan and Teeradet Supap

This post highlights a powerful statistical technique known as Synthetic Minority Over-sampling Technique (SMOTE) that was also used in combination with Categorical Boosting (Catboost) technique in our recently published work on development of a predictive degradation model of amine used in CO2 capture process. Theoretically, SMOTE is...

ICLER team visit to KNUST and UMAT Universities of Ghana

Last November, the ICLER program Chair together with some members of the team paid a visit to two universities in Ghana: Kwame Nkrumah University of Science and Technology (KNUST), in Kumasi, and the University of Mines and Technology (UMaT), in Tarkwa. The purpose of the visit was to explore the possibility of collaboration between CETRI and the universities for students’ exchange, as well as share ideas and discuss valuable inputs from both sides in relation to carbon capture, utilization and storage.

Production of Clean Energy: What Can Engineers Do?

Raphael Idem, PhD, P.Eng. – Clean Energy Technologies Research Institute Faculty of Engineering & Applied Science – University of Regina

Abstract: Energy is required for industrialization and maintaining/improving our standard of living. At the moment, the majority of the energy is sourced from fossil fuels. This leads to the generation of GHGs, especially CO2, which is blamed for global warming and climate change. Many useful strategies have been conceived to mitigate this issue. None is a silver bullet. Therefore, one policy fits all type solution may not work. What is needed is to select and mix strategies depending on the natural resources of each jurisdiction. The challenge lies in finding the most effective mixing formula for the least cost per jurisdiction such that the targets on environment, economy and society’s living standard are met. These are tasks engineers perform, which may involve research, development, design, construction, operation, etc.

This presentation discussed the strategies and the varied roles engineers can play based on their best strengths to achieve cost-effective solutions that meet the targets.
