Re ''The Coal Trap'' (editorial, May 30):
A recent study by the Department of Energy's Idaho National Laboratory shows that coal-to-liquid diesel fuels will be at least as clean as the fuels they replace, or cleaner. In fact, the laboratory concluded that coal-to-liquid fuels can be up to 46 percent cleaner in terms of carbon dioxide emissions using a biomass co-feed.
The laboratory also found that coal-to-liquid fuels will dramatically reduce emissions of harmful pollutants like nitrogen oxide, sulfur dioxide and particulate matter. (emphasis - JtM)
The Idaho National Laboratory report is a case study of a real-world coal-to-liquid facility set for construction in southeastern Ohio. A limited package of federal support for coal-to-liquid fuels is needed to reduce America's foreign oil dependency and to guard against foreign energy cartel price manipulation.
A robust domestic coal-to-liquid industry offers the dual benefit of greater energy security and environmental performance.

"According to the year-long INL study of the Ohio River Clean Fuels project modeling, Baard’s CTL fuels will yield 46 percent less emissions of carbon dioxide and other greenhouse gases than conventional low-sulfur diesel transportation fuels. (Carbon dioxide emission reductions are achieved using a 30 percent biomass co-feed, carbon capture and storage technology, and combined cycle, co-generation processes.) All emission reductions documented in the study were measured on a wells-to-wheels basis using the Argonne National Lab GREET (Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation) model of transportation fuels.
The INL study demonstrates that CTL fuels produce dramatically fewer emissions of regulated pollutants when compared to low-sulfur diesel fuel. Baard’s virtually sulfur-free CTL fuel will reduce emissions of sulfur dioxide by more than 80 percent and cut nitrogen oxide emissions by more than 20 percent. In addition, INL found that Baard’s CTL fuel will reduce particulate matter emissions by nearly 20 percent, slash emissions of volatile organic compounds by close to 20 percent and also reduce emissions of carbon monoxide...".
Yeah, yeah, we know - there is the biomass co-feed stipulation, but we've been urging that, anyway. And, instead of storage, we can use the CO2, along with waste heat, to generate the needed biomass.

The Semet Tar Ponds project has already been intensely studied and cleanup efforts have long been under way.
In the summer of 1995, Honeywell performed an interim remediation effort by putting a temporary cover on the Semet Tar Ponds, primarily to reduce emissions and odors. This cover is replaced annually. Honeywell also launched a scientific investigation into the characteristics of the materials there, leading to the discovery of a way to convert the Semet tar material into a high-BTU-content fuel. Pilot studies have proven that this hazardous waste can be safely recycled."
One of Honeywell's early enterprises was the manufacture of various products from coal tar - and, they were obviously careless about what they did with the wastes. But, here we have a case somewhat analogous to the Schuylkill, PA, coal-mine-refuse-to-liquid-fuel enterprise.
It emphasizes the point that there is value in coal waste. We should start looking at it as a resource, and focus our efforts on ways to use it constructively, rather than waste our time, as well as this potentially valuable asset, defending ourselves against the, sometimes justified, charges of environmental activists.
