The French government’s decision to ban some short-haul flights if there is a rail alternative under two and a half hours is only symbolic, says Andrew Murphy at T&E. It would reduce French aviation emissions by only 0.8%. Expanded to rail journeys under five hours and it’s still only 4.5%. Long-haul flying is the much bigger problem, but the resulting emissions are outside of France’s current climate target. Instead of just talking about … [Read more...]
Which sectors need Hydrogen, which don’t: Transport, Heating, Electricity, Storage, Industry?
Which sectors are most suited to hydrogen, and which are not? For the answer, six academics from the UK and the Netherlands - Tom Baxter, Ernst Worrell, Hu Li, Petra de Jongh, Stephen Carr, and Valeska Ting – use their areas of expertise to neatly summarise hydrogen’s pros and cons in Road and Rail, Aviation, Heating, Electricity and Energy Storage, and Heavy Industry. Their general message seems clear: hydrogen is still very expensive, so it can … [Read more...]
UK rail: where are the electric-diesel hybrids, hydrogen, battery trains?
Cars and planes get much more attention than trains when it comes to emissions. That makes sense when, in the UK, transport accounts for 26% of all carbon emissions but only 1% of this comes from trains. Also, trains are already relatively emission-low: they release 0.046kg of COâ‚‚/km/passenger while a diesel car is more than double that. Marcus Mayers and David Bamford at Manchester Metropolitan University explain that the crucial difference is … [Read more...]
