Producing hydrocarbon fuels from air and electricity?

Publish date: October 7, 2011

Air Fuel Synthesis (AFS) is claiming to be able to produce hydrocarbon fuels from air and electricity and is preparing a demonstration project.

The proposed method involves reacting sodium hydroxide with carbon dioxide from the air and electrolysing the resulting sodium carbonate to form pure carbon dioxide. Hydrogen is produced by electrolysing water vapour captured with a dehumidifier.

‘All the chemists say it won’t [react] but it will,’ said Tony Marmont, company chairman and a visiting professor at Loughborough University. ‘All I can say is it will. CO2 is reckoned to be an inert gas but I’m afraid it isn’t.’

AFS says its process only uses around 21.4KWh of electricity to produce one litre of fuel with an energy conversion efficiency of around 45 per cent.

The firm is planning to open a five-litres-a-day pilot plant in Teeside, funded by private investors, before the end of the year. Once the company has proved the concept, it hopes to commercialise it as a way for companies with vehicle fleets and for communities in remote locations to produce their own fuel using renewable electricity.

The role of CCS in Germany’s climate toolbox: Bellona Deutschland’s statement in the Association Hearing

After years of inaction, Germany is working on its Carbon Management Strategy to resolve how CCS can play a role in climate action in industry. At the end of February, the Federal Ministry for Economic Affairs and Climate Action published first key points and a proposal to amend the law Kohlenstoffdioxid Speicherungsgesetz (KSpG). Bellona Deutschland, who was actively involved in the previous stakeholder dialogue submitted a statement in the association hearing.

Bellona’s new working paper analyzes Russia’s big LNG ambitions the Arctic

In the midst of a global discussion on whether natural gas should be used as a transitional fuel and whether emissions from its extraction, production, transport and use are significantly less than those from other fossil fuels, Russia has developed ambitious plans to increase its own production of liquified natural gas (LNG) in the Arctic – a region with 75% of proven gas reserves in Russia – to raise its share in the international gas trade.
