    And there you have it. One of the two hardest techs to convert to 100% renewables (when H2 from )-is being converted a decade early World’s first liquid H2 fuel cell cruise ship combines 3.2MW H2 with and will operate in 2023

    Two measures have now been proposed to IMO: adding CH4 slip to the EEDI to avoid tradeoffs between CO2 and GHGs, and setting a CH4 slip standard for engines based the performance of high pressure systems. OEMs can support both if they believe CH4 slip can be managed.

    Wow, January 2020 was the warmest on record and greater than 3°C above the 1981-2010 climate average in Europe. The average global temperature was also the highest on record. 🔥 More info ():

    Shipping companies are increasingly turning to less expensive liquified natural gas, which is cleaner burning than conventional fuel oil, to power their fleets. But a new study suggests that move is actually worse for the climate. Here’s why.

    It’s now clear that if the world is to meet the climate targets it promised in Paris, natural gas, like coal, must be deliberately and rapidly phased out. There’s no time for a bridge. And clean alternatives are ready.

    I just listened to with on Podcast: Does shipping have a gas problem? Very interesting findings by Hope we can hear from LNG sector and their views on this.

    "Switching ships to LNG is worse than doing nothing.” In 2013, the organization behind this report, International Council on Clean Transportation, exposed Volkswagen's cheating on emissions from its diesel cars.

    For the curious, by estimates LNG has no climate benefit for cruise ships even over the long-term (100 year GWP).

    I participate in ⁦⁩ env meetings and can attest that good data are appreciated and very unlikely to “just persuade national delegations to the IMO to vote for business as usual and forget any future environmental progress” out of frustration.

    Independent of Arctic routes, the shift toward low and zero carbon fuels, renewably generated and with a lower energy density than HFO, will open up new challenges to centralized fossil fuel bunkering. New study out soon to start unpacking this.
