Motivated by possible future applications in low pressure drop reactors for hydrogen production by fixed bed chemical looping steam reforming (CLSR), novel high porosity fibrous mats of aluminosilicate fibres have been investigated as a substrate for Ni/Co oxygen carriers (OC's). When compared...

The aim of this work was to assess the technical viability of glycerol/fat co-gasification. The gasification performance was studied in a downflow fixed bed reactor using steam as oxidizing agent. Tests were performed with a mixture of 10% of fat and 52% of water, and the effect of temperature...

In Germany decarbonization of the electricity sector by fostering renewables and now phasing out coal-fired power is on track to reach the 2050 de-carbonisation targets, while decarbonising non-electric energy consumption is proving to be more difficult. The present discussion of a national...

This paper analyses whether ammonia can be viewed as an economically efficient and technologically suitable solution that can address the challenge of large-scale, long-duration, transportable energy storage in the decarbonized energy systems of the future. It compares all types of currently...

Current research into the pattern of energy usage in South Africa reveals an extraordinarily heavy reliance on coal-fired electricity, a strategy that is not only unsustainable but which has resulted in serious air pollution problems. The paper argues that this development ought to be seen in...

Nowadays, the global warming is considered as a world problem because it influences the environment by increasing the average temperature of earth surface. One of the greenhouse gases that release from human activities and fossil fuels combustion in industry is CO2. Several technologies are...

Some of the components of the climate system, the oceans and biosphere primarily affects the concentration of greenhouse gases in the atmosphere. Plants take CO2 from the atmosphere and convert it in the process of photosynthesis, carbohydrate. In the industrial era, human activities have...

This paper presents a brief literature review concerning the costs and benefits of electric vehicles and hybrid electric vehicles, highlighting their advantages in terms of greenhouse gas emissions reductions. Even though electric and electro-hybrid vehicles must still overcome many cultural and...

In order to have sustainable development, it is necessary to manage energy use and greenhouse gases (GHG) emission in all production processes. The aim of this study was to compare wheat production in dryland and irrigated agroecosystems in terms of greenhouse gases (GHG) emission based on...

The paper presents part of the overall United Nations Environment Programme Mediterranean work on the Implications of Future Climatic Changes for the Mediterranean Coastal Region. Most of this was published in Climatic Changes and the Mediterranean; Environmental and societal impacts of climatic...
