The level of renewable use is now so high in Germany that serious electric grid reliability and stability issues now exist which require both fossil power plant emergency backup for failed renewable production and dictate rejecting renewable energy to ensure operation of fossil plants required for electric grid reliability and stability.

When China halted plans for more than 100 new coal-fired power plants this year, even as President Trump vowed to “bring back coal” in America, the contrast seemed to confirm Beijing’s new role as a leader in the fight against climate change.
But new data on the world’s biggest developers of coal-fired power plants paints a very different picture: China’s energy companies will make up nearly half of the new coal generation expected to go online in the next decade.
These Chinese corporations are building or planning to build more than 700 new coal plants at home and around the world (…)

The United States has a broader array of energy options than China does. However, China is innovating and investing heavily in what it has, and some of the transformations it is achieving already are truly impressive.
China’s leaders have made a strategic choice about the direction of the country: They are aiming to shift from an economy based on heavy, polluting industries to one driven by technology and innovation. The political will for this upgrade has roots in both international geostrategic ambitions and domestic popular grievances about lagging standards of living—and it is beginning to bear fruit. In the process, however, vested interests and technical stumbling blocks have wasted resources and acted as a ballast against Chinese progress. China has the potential to do much more, and the international community should push it to achieve that potential.

New coal plants in Africa are largely being paid for by China and developed countries that are turning away from the technology at home.

Anyone with doubts about China’s demand for energy including for thermal coal needed to sustain its gigantic economy should cast their eyes over the latest statistics for power generation from Beijing’s National Statistics Bureau.
These data are a treasure trove in terms of revealing trends in China’s energy production and appetite for thermal coal sourced from both inside China and from imports shipped from countries including, Australia, Indonesia and Russia.

A l’origine de la révolution industrielle, le charbon demeure au XXIe siècle une énergie privilégiée dans le monde. Il permet d’assurer les besoins énergétiques de l’équivalent de presque un homme sur trois (le charbon satisfait 29% de la consommation d’énergie finale en 2012 selon l’AIE). Il est la première source d’énergie utilisée pour produire de l’électricité (environ 40% de l’électricité mondiale est produite à partir de charbon).

China’s natural gas production surged to a record last month and coal output rebounded as economic growth accelerated power use in the world’s largest energy user.
Natural gas production in March rose 8.2 percent from the average of the first two months of the year to a record 13.6 billion cubic meters, according to data Monday from the National Bureau of Statistics. Coal output rose almost 13 percent over the same period to average 9.67 million tons a day, the highest daily level since December, according to Bloomberg calculations based on the data.

The resurgence is due to the industry making itself more competitive, in much the same manner that the shale oil & gas players made themselves more competitive in response to a collapse in commodities prices.

Chinese engineer and inventor Feng Weizhong has an easy answer to how China plans to keep slashing coal use and power-station emissions while relying on coal to provide at least 55 per cent of its massive energy demand for decades to come. The effervescent Professor Feng, who is also general manager of a large Shanghai power plant, explained to The Australian how the country can contrive to do both at the same time. “Simple! It’s clean coal!”

Des chercheurs allemands étudient la possibilité de transformer dans la région de la Ruhr une mine de charbon en un site de stockage hydroélectrique. En Rhénanie-du-Nord-Westphalie (ouest de l’Allemagne), l’extraction au sein de la mine de charbon de Prosper-Haniel a débuté en 1863. Une procédure de fermeture de cette mine, qui fournit encore près de 2,5 millions de tonnes de charbon par an(1), devrait être engagée fin 2018. Mais l’activité ne devrait pas s’arrêter sur le site : il est prévu que la mine soit transformée en une station de transfert d’énergie par pompage (STEP).

Just a few short years ago, few would have dared to predict that coal could have a future in the energy policies of emerging and developed countries alike. Yet the fossil fuel is undergoing an unexpected renaissance in Asia, buoyed by technical breakthroughs and looming questions about squaring development with energy security.
