The bravest recovery strategies will invest robustly in new yet-to-take-off clean energy technologies. If you are going to have to spend hundreds of billions to revive your economy isn’t it better to replace the old with the new rather than prop up what you’ll have to abandon soon anyway? In anticipation of that happening, new technologies are lining up. Here, Cédric Philibert at the IFRI Centre for Energy & Climate summarises their detailed … [Read more...]
Green Ammonia can replace fossil fuel storage at scale
What’s the best way to store energy, from industry scale to electric vehicles, replacing the widespread use of fossil fuels? Pure hydrogen is an energy dense alternative, but the gas takes up a lot of space. Liquid ammonia doesn’t, yet it contains the hydrogen and therefore the energy. Ian Wilkinson at Siemens explains the advantages of using ammonia, NH3. Already the world produces 180m tonnes a year, worth €80bn. It’s mainly for agricultural … [Read more...]
The outlook for Powerfuels in aviation, shipping
The development and commercialisation of powerfuels is in its very early stages. Powerfuels are synthetic gaseous and liquid fuels produced from green electricity. The plan is to use them when there is no viable alternative, like aviation and shipping. The big hurdle is cost, currently in the range of €3-5/litre, or five to ten times the price of fossil fuels. Dolf Gielen and Gabriel Castellanos at IRENA and Kilian Crone at the German Energy … [Read more...]
Shipping: commercially viable zero emission deep sea vessels by 2030
Last year the International Maritime Organization, recognising the slow progress the sector had made, set ambitious targets to reduce shipping emissions by at least 50% by 2050 compared to 2008. Companies started lining up to face the challenge. But the shipping sector is very energy intensive. Bunker fuel costs can account for 24 - 41% of total shipping costs, so any clean fuel transition must be competitively priced. The fact that alternatives … [Read more...]
