Wärtsilä and partners developing emissions-free barge concept

Green Car Congress

The concept is supported by the Dutch Ministry of Infrastructure and Water Management. The concept is based on the use of replaceable battery containers, to be known as “ZESPacks”. To make it easier for barge operators to sign-on to the concept, a ‘pay-per-use’ financing model has been developed.

New Lithium rechargeable semi-solid flow cell offers energy densities an order of magnitude greater than previous flow batteries; possible applications in transportation and grid-scale storage

Green Car Congress

The new semi-solid flow cells, which can use established lithium intercalation compounds, could deliver energy densities of 300–500 Wh L -1 (specific energy of 130–250 Wh kg -1 ) at system-level costs, depending upon the chemistries, of $250 kWh -1 and $100 kWh -1 for transportation and grid level storage, respectively, the researchers conclude.

DOE awarding $35M to 11 projects for hydrokinetic turbine development; ARPA-E SHARKS

Green Car Congress

Hydrokinetic energy is an abundant renewable resource that can boost grid resiliency and reduce infrastructure vulnerability, but it is currently a cost prohibitive option compared to other energy generating sources. These methodologies will significantly decrease the levelized cost of energy (LCOE) of the final HKT design.
