Total cost of carbon capture and storage implemented at a regional scale: northeastern and midwestern United States.

We model the costs of carbon capture and storage (CCS) in subsurface geological formations for emissions from 138 northeastern and midwestern electricity-generating power plants. The analysis suggests coal-sourced CO emissions can be stored in this region at a cost of $52-$60 ton, whereas the cost to store emission from natural-gas-fired plants ranges from approximately $80 to $90. Storing emissions offshore increases the lowest total costs of CCS to over $60 per ton of CO for coal.

Diatoms: a fossil fuel of the future.

Long-term global climate change, caused by burning petroleum and other fossil fuels, has motivated an urgent need to develop renewable, carbon-neutral, economically viable alternatives to displace petroleum using existing infrastructure. Algal feedstocks are promising candidate replacements as a 'drop-in' fuel. Here, we focus on a specific algal taxon, diatoms, to become the fossil fuel of the future.

Continents divided: Understanding differences between Europe and North America in acceptance of GM crops.

The differences between GM policies in the US and Europe have several causes. GM technology holds a home court advantage in the US and European chemical companies did not support its introduction. The technology did not seem to provide benefits to consumers, and the crops it applied to were not so significant in Europe.
