IRENA is predicting the future of liquid biofuels by monitoring the number and technology-type of patents. It’s not looking good. The first thing to note is that, after a promising rise, the total number of patents has slid from over 6,000 in 2011 to around 2,500 in 2017. That’s reflected in the dramatic fall in global biofuel investments, from $27bn in 2007 to $2bn in 2017. The likely main cause is a lack of stable regulation, say Alessandra … [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...]
UK’s net-zero ambition: counting all emissions, not just in-country
The UK’s Committee on Climate Change (CCC) has advised its government to go zero-carbon by 2050. But, say Joe Blakey and Marc Hudson of the University of Manchester, counting all emissions means counting the carbon footprint of imports too. Including these (and excluding emissions from exports) the UK’s footprint is 70% higher than the figure used by the CCC. The same is likely true for all high income economies. And the cost of successful … [Read more...]
Sails make a comeback as shipping heads for complete decarbonisation by 2035
Last year’s ITF report asserts that an almost complete decarbonisation of shipping could be achieved by 2035 using currently known technologies. Whilst LNG is gaining momentum, hydrogen, ammonia and biofuels could be more sustainable means of delivering much of the required reductions, complemented by a mix of electronic propulsion and wind assistance. The message, according to independent journalist Eric Marx, is “Hold on. There’s a decade of … [Read more...]
Shipping: regulations facilitating switch to LNG
How do we solve shipping’s “chicken-and-egg” dilemma: LNG producers wait for enough ships to run on LNG, while shipping companies wait for producers to increase their supply? The ‘virtuous circle’ of steady growth in LNG shipping in the North Sea/Baltic Sea area can provide an important case study for the rest of the world, according to a reportby the Oxford Institute for Energy Studies. It concludes that LNG will grow as a shipping fuel … [Read more...]
Shipping to halve carbon footprint by 2050 under first sector-wide climate strategy
Global shipping must at least halve its emissions by 2050, according to an international deal adopted on Friday. Reaching an agreement on how to achieve this goal will be difficult as countries already challenge many proposed measures, writes Sara Stefanini of Climate Home News.
