Cornerstone Mag

Cornerstone, the official publication of the world coal industry, was launched by the World Coal Association in the spring of 2013. Cornerstone is an internationally recognized, high-quality, objective publication that includes content investigating all aspects of the global coal industry. The electronic version is offered free of charge through this website.

“Although coal and renewable energy sources might appear to be strange bedfellows… we could see increased deployment of combinations of the world’s two fastest-growing energy sources becoming a reality.”

The Energy Frontier of Combining Coal and Renewable Energy Systems

MillDecorativePhotoCorrectedSizedThe world is undoubtedly hungry for energy and this hunger is growing. There are strong incentives to develop improved sources of energy. By 2040, the world’s population will have reached nearly nine billion.1 All of these people will need to be housed, fed, and have the opportunity to make a living; this inevitably means that much more energy is going to be needed. By 2040, global energy demand will be about a third greater than current levels.2

Developing Country Needs Are Critical to a Global Climate Agreement

imageAs another round of climate talks approaches, recent headlines have highlighted the critical role developing countries play in achieving a climate agreement—and they are. Concerned about the restrictions it might place on their efforts to grow their economies and eradicate poverty, many developing countries are cautious about what a future global agreement on climate change might mean. With one billion people living in extreme poverty in addition to a similar number with incredibly low standards of living, it is hardly surprising that poverty eradication ranks number one on the list of priorities for developing country governments.1

The Flexibility of German Coal-Fired Power Plants Amid Increased Renewables

Opening ImageGerman energy policy is determined by different ambitious targets. That is especially true as far as the electricity sector is concerned. The main characteristics of electricity-sector policy are a complete phasing out of nuclear energy, the transition to a power supply based mainly on renewable energy, and the reduction of energy consumption by continuously increasing efficiency. The main purpose of these changes is to reach a nearly CO2-free power supply by 2050. The central challenges are keeping the power system stable and secure while maintaining consumer electricity prices at a competitive, affordable level.

Exploring the Status of Oxy-fuel Technology Globally and in China 

Zheng-Fig3Oxy-fuel technology is characterized by the use of pure oxygen or oxygen-enriched gas mixtures to replace air during combustion of (most often) fossil fuels. After the fuel is burned, flue gas with a high concentration of CO2 is generated, which facilitates the capture of CO2. First proposed by Abraham in 1982, the purpose of the technology was to produce CO2 for enhanced oil recovery (CO2-EOR).1 As concerns related to climate change have intensified, the need to control CO2 emissions (as the principal greenhouse gas) has also gradually increased in prominence. As a technology option with great potential for reducing CO2 emissions, oxy-fuel combustion has become a focus of research worldwide.2
