Convoy survey: Trucking divided on sustainability, climate change

Small and mid-size trucking operators have mixed views on sustainability, especially on the viability of electric vehicles (EVs). There seems to be some split between younger operators and older ones, with the younger ones much more attuned to an acceptance of sustainable requirements.

Convoy, the surveying organization, operates a load matching service, which helps truckers reduce deadhead or empty runs, and therefore makes a contribution to sustainable operation. , as well as earning more for truckers.

It’s no surprise that the initial cost of new EVs is a serious problem for these smaller truckers. Even with lower maintenance and operating costs, the shortage of charging stations and repair facilities means buying a new EV truck is not an option most of these folks are considering.

However, they are concerned about operational cost savings, and the factors preventing EV use should decline in significance as more of them hit the road. When petroleum fuels are so high-priced, the electric alternative looks more practical.

It will be a few years before the number of charging stations will be large enough for many truckers. However, fleets with shorter day-long routes, roughly 250-300 miles or less, which return to a base station, are natural candidates for EV trucks. If manufacturing can get going, we will see these operations choosing new EVs, since the y can control the needed infrastructure.

It will take longer to satisfy the owner-operator crowd that there are enough charging stations. I have not seen a significant study of the density of charging stations or their placement to support general truck movements, say based on the Convoy to-from waybills. Knowing where charging is needed would go a long way toward defining how to proceed.

Low loads double methane slip on LNG carrier voyage

A study by scientists from Queen Mary University oof London scientists measured methane and CO2 emissions from marine power sources. They instrumented a new LNG carrier (2021 completion), on both the main engines and the generator engines.

Note that generator engine emissions are not considered in monitoring the emissions from a ship, according to current standards.

The methane slip, escape of methane through gaps and orifices in the machinery, was found to be quite low, and the generator engines were found to be the biggest source.

This is a quite new ship and one might expect lower emissions from the latest technology. But the study points to the need for including generator engines in the rules and in the monitoring. Studies on other ships and other voyages would be a good idea, and to their credit, the ship owner, Cheniere, has said it will continue to study emissions from its fleet.

Power cuts hit China factories and give container shipping another shock

What else could go wrong for supply chains? Now government-imposed power cuts are threatening factory output in China.

The cuts in power generation are due to the Chinese government’s desire to keep emissions down to their target.
