Coal gasification and fuel cells – better than CCS? by Justin Blows

According to this report, there is growing interest in a new way of exploiting coal in which coal is gasified underground to produce hydrogen and carbon dioxide and the hydrogen then used to power a fuel cell. Coal gasification is explained here

Advocates claim that this approach will be cheaper and more
environmentally friendly than using coal fired power stations with carbon capture and storage. Apparently, the impact of the mining process is reduced and moving coal around is avoided altogether.

Australian clean coal technology specialist Linc Energy and British fuel cell firm AFC Energy have entered a partnership in this area. I found these patents by AFC energy.

Clean Coal refused Clean Development Mechanism status – again. by Justin Blows

According to this report, a decision has been made in the Copenhagen meeting to exclude clean coal from the Clean Development Mechanism (CMD).

The CDM mechanism provides carbon credits to developed nations in return for investment in sustainable projects in the developing world, such as renewable energy and methane gas capture projects.  The CMD scheme has the potential to significantly lower the costs of the deployment of technologies such as clean coal, increasing their competitiveness.

Apparently, Brazil and allied countries blocked the inclusion of clean coal into the CDM.

This is another blow for clean coal which has been recently attacked as being unviable and too late to make a difference. Many believe, however, that clean coal is an essential technology if the world is to get any where near the required carbon reduction targets.

Grown packaging material to replace polystyrene by Justin Blows

Polystyrene based packing materials are a major waste headache.  This sort of material can escape into the environment and contribute to environmental catastrophes such as the Great Pacific Garbage Patch also known as the North Pacific Gyre – an area  at least the size of Texas full of plastic, down to about a depth of  about six metres  (Read here about a man’s attempt to SWIM across this Texas size piece of ocean) 

Now, the people at ECOVENTIVE have come up with a reportedly patented idea for a more environmentally friendly packing material which they call ECOCRADLE .   Apparently, a growing organism is used to transform agricultural byproducts like cotton seed hulls and buck wheat hulls into a protective packaging materials with properties similar to polystyrene – except it is biodegradable.

Apparently, the organism grows quickly, in just 7 days it produces miles of tiny white fibers which envelope and digest the seed husks, binding them into a final product. The entire process is reported to use about 10 times less energy per unit of material than the manufacturing of synthetic foams.
