Claverton Hydrogen Storage on IGCC Sites

Dear Neil

You asked if it would be practical to store syngas as a method of allowing IGCC-CCS plants to respond to the overnight fall in demand

The prospects of the on-site storage of syngas, to enable an IGCC to vary its output seem limited. The gas that would have to be stored would have to be hydrogen. Otherwise, the processes by which the carbon in the syngas is removed would have continuously vary their throughput. Only the gasifier and air separation unit ( for supply of oxygen) would run at a constant output

Unfortunately, a very large amount of gas is produced when gasifying

Prof Klaus Illum talks about atmospheric C02 levels and climate change

From – Klaus Illum3 February 2009 The time scales of the graphs above and below differ by a factor 1,000. The composition of the atmosphere (H2O, NH3, N2O, CH4, O2, …..) has changed during the last hundreds of millions of years. During the last hundred thousands of years the CO2 concentration has fluctuated at a […]

The NASA Climate Scientist James Hansen – urgent warning

The NASA Climate Scientist James Hansen and an international team of researchers have very recently completed a paper for the Open Atmospheric Science Journal, concerning an in-depth analysis of Climate history at the Earth’s Polar regions, relating it to today’s warming conditions.

Published on 7th November 2008, the peer-reviewed research paper shows, by careful calculations on proxy data for the very distant past, that we should expect high Climate Sensitivity, the warming signal of the Earth in response to Greenhouse Gas accumulation above ground.

The team looked at the relative changes in Carbon Dioxide concentrations in the Earth’s atmosphere and showed that the rate of change showed strong negative “radiative forcing” clearly associated with the formation of the polar ice caps, and used that as a basis for calculating the Climate Sensitivity.

Squaring the Circle on Coal – Carbon Capture (CCS)

By Chris Hodrien

2008 Claverton Conference Paper Synopsis: Huge global reserves of coal remain, well-distributed among relatively stable supplier nations, and its production is increasing. With the recent rapid increases in oil and gas prices, especially in the UK, it is again becoming the minimum cost option for power generation and heavy industry. Large thermal (steam turbine) powerplant is also the global utilities’ preferred generating option because of its predictability/reliability, operational characteristics, retrofit to existing powerplant sites and “fit’ to the existing grid structure.
