Mærsk Group exploring use of lignin-based marine biofuels; CyclOx and B21st

Green Car Congress

With an annual fuel bill of US$7 billion for vessel operations, the Mærsk Group continually considers ways to reduce its bunker fuel consumption. Greater efficiency is the primary way of achieving this; alternative fuels are another. —Jacob Sterling, head of Environment and CSR, Mærsk Line. Earlier post.).

DNV GL paper suggests near-term success for LNG in shipping; alternative fuel mix to diversify over time

Green Car Congress

Well-to-Propeller GHG emissions results for marine alternative fuels. DNV GL has released a position paper on the future alternative fuel mix for global shipping. Shipping must change, and we must contribute technical measures, operational measures and alternative fuels to meet the challenges we are tackling.

The Case for Nuclear Cargo Ships

Cars That Think

At the same time, it’s becoming apparent that alternative-fuel solutions we’re looking at have big drawbacks, and that producing these fuels will take a lot of green power that will be needed to replace coal and gas on shore. It’s becoming more and more apparent that we need to do something about emissions,” he notes. “At

Study: alcohol, biomethane and ammonia are the best-positioned fuels to reach zero net emissions for shipping; OPEX, not CAPEX challenge

Green Car Congress

The energy conversion rate of this system is higher than that of biomaterial-based systems, but the production pathway cannot tap into potential energy sources as e.g. waste biomass. The main challenge for ammonia is that it is highly toxic and even small accidents can create major risks to the crew and the environment.

NRC report finds that large-scale production of algal biofuels poses sustainability concerns; not a definitive barrier

Green Car Congress

One of the primary motivations for using alternative fuels for transportation is reducing greenhouse gas emissions. The introduction of large-scale algae cultivation systems in arid or semi-arid environments could alter the local climate of the area by increasing humidity and altering temperature extremes.
