why are we still using coal?

Coal use has declined overall during the pandemic, despite a sharp increase in energy consumption in China, whose strong economic growth and heavy reliance on its coal-fired power plant infrastructure means that the overall decline in consumption has only reached a paltry 0.8%. Other countries, such as Japan, continue to build coal-fired power plants, jeopardizing the global target, while other coal powers such as Australia, Germany and India are beginning to set targets to close mines and transition to renewables, decisions that the figures more than justify. Coal consumption in the United States has been in free fall since 2019, the year that also marked the beginning of the end of coal in Europe, implying that even heavy industries such as steel are switching to renewables and dramatically reducing pollution levels in some areas.

Europe is moving much faster than expected: several countries have already closed all their coal mines; Belgium, Austria and Sweden have shut down all coal-fired power plants while others are in the process of doing so. Other countries are showing that they can live without coal for long periods of time.

However, in global terms, the figures show that we still have a problem: explosive growth in China and India has led to the world doubling its coal-fired power generation capacity to 2,045GW since 2000, plus another 200GW under construction and 300GW in the pipeline. Plant closures in Europe and the US have meant 268GW less for the time being, with 213GW more already planned, and the actual amount of coal-generated power has leveled off since 2014, meaning that built plants are operating fewer hours and are therefore even less profitable than expected. In total 19 of the 80 countries operating coal-fired power plants have already set a date for their total closure.

In practice, this is a loss-making industry in which large investment funds and some sovereign wealth funds such as Ireland and Norway are no longer investing in, but from which we do not seem to be able to free ourselves. Developed countries burned (and continue to burn) coal for decades, but that doesnt justify developing countries doing the same now. At some point it will be necessary to single out, sanction or isolate countries that continue operating coal-fired power plants if global emissions targets are to be met.

The scientific community agrees that the world urgently needs to stop burning coal, given that we already have energy sources that are not only significantly cheaper, but are also compatible with more productive uses of land. Coal is simply an outdated and harmful technology long overdue for retirement. What are we waiting for?

factors affecting strength and durability of densified biomass products - sciencedirect

Effectiveness of a densification process to create strong and durable bonding in densified products such as pellets, briquettes, and cubes can be determined by testing the strength (i.e., compressive resistance, impact resistance, and water resistance), and durability (i.e., abrasion resistance) of the densified products. These tests can indicate the maximum force/stress that the densified products can withstand, and the amount of fines produced during handling, transportation, and storage. In this article, the procedures used for measuring the strength and durability of the densified products are discussed. The effects of constituents of the feed such as starch, protein, fiber, fat, lignin and extractives; feed moisture content; feed particle size and its distribution; feed conditioning temperature/preheating of feed; added binders; and densification equipment variables (forming pressure, and pellet mill and roll press variables) on the strength and durability of the densified products are reviewed. This article will help select process parameters to produce strong and durable densified products from new biomass feedstocks or animal feed formulations. Guidelines for developing standards on criteria for the acceptance levels of strength and durability of the densified products are presented.
