On stream

Have your say

I UNDERSTAND The Scotsman intends to publish an energy supplement on Monday, as a follow-up to the Fracking Conference held on 11 December.

One of the conference speakers, Allan MacAskill of Scottish Renewables, appeared unaware in his comments of recent developments in tidal-stream power generation at the Pentland Firth. He seemed to suggest tidal power generation was 20 years away.

In September this year the Scottish Government consented the first tidal power station at the Pentland Firth to Meygen, a company owned by Atlantis Resources. Construction is due to begin in the second quarter of 2014. Once built, it is estimated to generate 86 megawatts. A new power link is also planned to southern Scotland from the Gills Bay/Canisbay area to transport the Pentland Firth energy south.

It is intended that this will be the first of many new major tidal-stream projects in Scotland, and I hope your energy review will not overlook the importance of the forthcoming tidal-stream power generation developments.

I SEE Algy Cluff is proposing that coal under the Forth be subjected to underground gasification (your report, 12 December).

Ironically, he proposed this ­bizarre idea at the Fife Renewables Centre. It runs counter to the whole notion of renewable energy because partial ignition of coal using underground ­oxidation produces two gases – carbon monoxide, which is highly toxic, and carbon dioxide, which causes atmospheric heat retention. This will, in due course, leak to the surface and result in further climate change.

This is the precise reverse of carbon capture, which is what the renewables industry is proposing as one possible solution to the inexorable increase of atmospheric carbon dioxide.
