A reader is impressed with Cheung Kong Infrastructure's (CKI) plans to use hydrogen as the fuel of the future.
CKI executive director Barrie Cook is promoting hydrogen as a back-up power solution for buildings in the Asia-Pacific region.
In a joint effort with Canada's Stuart Energy Systems, CKI wants to replace dirty diesel generators with cleaner hydrogen systems.
Quiz for readers: what, if anything, is wrong with the following statement: 'When you burn hydrogen, you produce oxygen and water . . . That's the beauty of it. Emissions are basically zero.' It's from a local newspaper article.
Quiz answer: According to our reader, David Webb, who knows his elements as well as his share price charts, this is nothing less than alchemy. Creating one basic element from another simply can't be done. What you actually produce when you burn hydrogen is steam.
Dirty old coal would be needed to extract the hydrogen from water. 'So you burn coal to get hydrogen - not exactly emission-free, is it?' Mr Webb says.
