The future of electric power in displacement powerboats is really interesting and exciting.
10th Ave Terminal in SD is a relatively small dock for the Dole banana ships and break bulk carriers that periodically visit. Overall, ship visits are light as 99% percent of the SoCal shipping traffic goes to LA/SP and some to Oxnard. These particular docks are near hotels and residential homes with lower income families to the East.
This proposed little tug fits the definition of a harbor tug well, and will likely have limited run times/distances involved for its use case.
SD is also looking to install electrical shore power connections for the ships along this dock to reduce their Gen run time. IE, container ships in LA can have limited port time but break bulk ships doing their own offloading can be parked here for a week or more. Many of the bulk ships who visit are older, foreign flagged, and emit more unburned HC and Nox than newer ships, hence the desire for a electrical connection for shore power. And, I get it, some of the energy source will be hydrocarbon fuels to provide the electricity, but it’s a cleaner source of power than these old ships engines. California gets it power supply from a wide variety of sources (renewables constantly growing). We still import <10% from other states that burn coal, but we will be phasing out coal produced electricity by 2026.
A lot of people on TF believe man made climate change from fossil fuels is bogus even though the vast majority of climate scientists and others who have PHD/PE after their name have shown us otherwise. With the internet, social media, and forums, we have given a voice to many people who could barely sit through one required class of chemistry in high school, but now they have strong opinions on scientific matters and know more than the experts. At first it was distressing, now just amusing, and they are not going to change their opinions. Distrust of experts is something that has been whipped up in our recent past for a variety of uses, and very successfully I must say. I would therefore expect the usual negative comments towards people who are trying to make a difference and look for alternate solutions. As I stated before, it doesn’t matter what we think (myself included), the next generation gets to decide how they want to play this out. Manage your own destiny, or others will do it for you.
