@BBCScienceNews @MattMcGrathBBC As @Peters_Glen points out in kleinmanenergy.upenn.edu/energy-policy-… the first priority is emissions reductions. DAC (Direct Air Capture) powered by renewables has potential but the framing by Carbon Engineering / BBC on capturing carbon to create fuel is problematic on several levels. 1/n
@BBCScienceNews @MattMcGrathBBC @Peters_Glen Firstly, Road, Rail & Shipping even, being electrified making fuel redundant; and in a competing hydrogen economy with fuel, it would be non-carbon based one. Leaving Aviation: 13% of transport and just 3% of all sector global emissions. DAC focused on that no silver bullet. 2/n
@BBCScienceNews @MattMcGrathBBC @Peters_Glen Secondly, in terms of Govt financing, would we focus that on decarbonising road, or decarbonising aviation? DAC may be great to invest some $ in as Devt phase tech, but big $$$ need immediately in road sector. Not either / or in terms of end state, timing wise sorry it is. 3/n
@BBCScienceNews @MattMcGrathBBC @Peters_Glen Finally, worth stressing … the Carbon Engineering focus is on carbon capture for fuel, for burning. This makes zero change to CO2 in atmosphere. They will merely recycle it … it's CCE (Carbon Capture and re-EMIT) tech. So don't conflate with 'Carbon Capture and STORAGE' . End/n
