Most Maritime Shipping Battery Propulsion Studies Are Already Obsolete

Most maritime battery studies are already obsolete. That is not a criticism of the researchers who wrote them. It is a recognition that their assumptions were grounded in the battery costs and energy densities available at the time. Several of the most detailed recent merchant shipping studies modeled battery system … [continued]

Remote communities in the United States, who often rely on imported diesel to power their microgrids, are exploring the viability of using the powerful currents of free-flowing rivers to produce electricity using novel technologies like this hydrokinetic device installed on Alaska’s Kvichak River in 2019.
