What happens to wind power when there is no wind? Why it makes perfect sense that old, polluting and inefficient coal fired power stations should be retained and receive a capacity payment

This note argues that environmentalists will have to recognise that part (and a small price) of the price we pay for creating significant additional capacity of intermittent / variable renewables is the continued existence of coal fired plant, operating at a very low capacity factor. (And of course it will make us less vulnerable to […]

Carbon-free shipping – using renewables to create ammonia by electrolysis during peak periods to be used as shipping or aviation fuel

Carbon-free shipping. (Ed. – ammonia makes a very good aviation fuel) Ammonia (NH3) could be used as a carbon free fuel for shipping. It could be made from atmospheric nitrogen combined with renewable energy derived hydrogen. Ammonia’s hydrogen could react with oxygen to power engines, turbines or fuel cells, emitting N and H2O. Oxygen pre-separation […]
