New material could capture carbon more efficiently (Day 287)

A cleaner fossil-fuelled future is something that I, along with many of my colleagues, aspire to achieve during my lifetime. Carbon capture, storage and use, and its potential to mitigate climate change figures strongly on my research agenda.

So I was particularly pleased to learn that researchers from New Mexico State University (NMSU), US, have developed a new material that could capture carbon dioxide more efficiently and with greater capacity than any technology currently in place.

Now you may think this a bold claim, but the research focuses on adsorption as opposed to absorption – which is the most common method used for capturing carbon dioxide.

Nasser Khazeni, a chemical and materials engineering PhD student from NMSU, led and developed the research into this new technology, with specific focus on post-combustion separation of carbon dioxide.

Going the extra litre (Day 182)

In today’s blog we are heading towards Puerto Palomas, Chihuahua, Mexico, which is a small town with a population of around 5,000 people located just south of the US border near Columbus, New Mexico.

It’s a part of the world that has an average annual rainfall in the region of 361 mm (14.21 inches). In comparison, parts of the UK has more than ten times this level (4,577 mm or 180.2 inches).

Aquifer wellWater supplies for North and South of the border are drawn from the same aquifers, some of which are contaminated with arsenic and fluoride.

On the US side, the water is treated using a reverse osmosis system to provide all residents with clean water.

On the Mexican side, the water supply is only disinfected with chlorine. The levels of arsenic and fluoride contaminating the water supply is toxic to the people who drink it over a long period of time.
