Alkane Energy - a company that specialises in the capturing of waste coal methane and turning it into power - is trading up on the completion of 3 new projects.

Given that there's so much coal left in the world and India and China's clear intention not to decouple economic growth from rising carbon emissions, there ought to be a a good opportunity for Alkane to go international. Right now, they've only got one plant in Germany and 3 more on the way.

It's a shocking figure that China produces 35% of the world's coal but over 80% of the mining deaths - more than 6000 a year. I have heard that this is because Chinese miners like to smoke on the job, igniting any waste methane that may arise.

So there's a real opportunity for someone to get some carbon credits, set up a waste methane plant and save some lives into the bargain. China plans to increase electricity production by 6 times by 2020, so they need all the power they can get.
