Renewable Energy Investment in South Africa

South Africa faces the dual challenge of pursuing economic growth and protecting the environment. South Africa has set up the institutional infrastructure for renewable energy projects which are beginning to pay dividends in the form of big investments from foreign as well as local investors and development of commercial solar, wind and biomass energy projects. […]

Financial Aspects of CDM Projects

The primary goals of CDM projects are to promote sustainable development in developing countries and to allow industrialized countries to earn emissions credits from their investments in emission-reducing projects in developing countries. Any CDM project requires a tremendous amount of administrative work which makes carbon finance a complicated undertaking.  A wide array of transaction costs associated with […]

Biological Desulphurization of Biogas

Biogas basically consists of methane and carbon dioxide. In addition, it also contains unwanted contaminants, especially hydrogen sulfide (H2S). Hydrogen sulfide mainly occurs because of the degradation of sulfur-containing proteins (e.g. methionine and cysteine) or the desulfurization of sulfates. The fermentation of manure and other organic wastes shows typical H2S concentrations in the range of […]

Overview of Biomass CHP

Biomass CHP is the simultaneous generation of multiple forms of useful energy (usually mechanical and thermal) in a single, integrated system using biomass wastes. Biomass conversion technologies transform a variety of wastes into heat, electricity and biofuels by employing a host of strategies. Conversion routes are generally thermochemical or biochemical, but may also include chemical and physical. […]

Bioenergy in South Africa

South Africa is endowed with abundant renewable resources in the form of biomass, solar and wind energy. The Government’s White Paper on Renewable Energy Policy, released in 2003, supports the development of alternative energy systems with an ambitious target of generating 10,000 GWh green electricity by 2013. The introduction of Renewable Energy Feed-in-Tariff (REFIT) has […]

MENA’s Great Strides in Solar Sector

With the scheduled procurement of over 4 GW of solar power this year, the MENA region is making great strides toward establishing itself as a rising gigawatt-scale solar market. According to the Middle East Solar Industry Association (MESIA), over 3 GW was added to the MENA region’s pipeline in 2015.  Egypt firmly established itself as a hot […]

Energy Partnership in South Asia

South Asia has an interesting mix of countries displaying diversity in terms of natural resources, landscape, per capita income, culture, happiness index, etc. On the energy front all these countries today are facing a multitude of challenges in meeting their rapidly growing requirements in a sustainable manner. While governments of each of these countries have […]

Introduction to Hydrothermal Carbonization

Most would agree that the production of biofuels is important, even necessary, for our future. There are significant differences in the production of various biofuels, especially concerning the production of biocoal, which will impact the acceptance and use of biofuel in the future. This article focuses on one technology for the production of biocoal which […]

Bioenergy in Middle East and North Africa

There is a large potential for renewable resources in the Middle East which have remained more or less unharnessed. Apart from solar and wind, the Middle East also has abundant biomass energy resources which have remained unexplored to a great extent. According to conservative estimates, the potential of biomass energy in the Euro-Mediterranean region is […]

Renewable Energy in South Africa

South Africa, the most industrialized country in Africa, is highly dependent on conventional fuels which make it one of the largest emitters of greenhouse gases in the world. Coal provides around 75% of the fossil fuel demand and accounts for 90% of power generation in the country. A smooth transition to a low-carbon society requires […]

Break Free from Fossil Fuels

“Not in my back yard” a well known metaphor that explains the human actions, people were extremely happy when fossil fuels were found, the thought that their problems are finally going to be solved, not knowing the adverse effect of this discovery , and no one had questioned about the future. Probably now, while you are reading this article […]

World’s Largest CSP Plants

With mammoth CSP plants in varying states of operation all across the world, the search for the true ‘world’s largest’ plant generally points to either California, Nevada, or Morocco. But which is really the biggest? What is Concentrated Solar Power Using mirrors to concentrate the sun’s energy, CSP technologies upgrade traditional steam turbines or engines to create electricity from heat. And, […]

Storage Systems for Biomass

Sufficient storage for biomass is necessary to accommodate seasonality of production and ensure regular supply to the biomass utilization plant. The type of storage will depend on the properties of the biomass, especially moisture content. For high?moisture biomass intended to be used wet, such as in fermentation and anaerobic digestion systems, wet?storage systems can be […]

Waste to Energy Industry – Trends and Forecasts

Incineration, with energy recovery, is the most common waste-to-energy method employed worldwide. Over the last five years, waste incineration in Europe has generated between an average of 4% to 8% of their countries’ electricity and between an average of 10% to 15% of the continent’s domestic heat. Around 130 million tonnes of municipal solid waste […]
