MIT researchers propose subsea version of pumped hydro for renewable energy storage

Green Car Congress

Researchers at MIT are proposing using a variation on pumped hydroelectric systems for storage of electricity produced by offshore wind farms. These structures would serve both as anchors to moor the floating turbines and as a means of storing the energy they produce. Earlier post.).

MIT and Lamborghini file patent on new MOF material for supercapacitors

Green Car Congress

The collaboration began three years ago when Automobili Lamborghini joined the MIT-Italy Program, and took a further step forward in 2017 with the launch of two research projects, one with Professor Mircea Dinc? At MIT, the Dinc? The e-motor also supports low-speed maneuvers such as reversing and parking with electric power.

ExxonMobil, MIT and Synthetic Genomics team publishes results of LCA on algal biofuels; potential for large reductions in GHG

Green Car Congress

In the accumulation cases, oil accumulated and stored in the algal cells is extracted from biomass that is harvested from the growth ponds. The researchers examined three distinct oil recovery options: dry extraction, wet extraction, and secretion. The dry and wet extraction options fall in this class.

Novel Li-metal electrode design could lead to more powerful solid-state batteries

Green Car Congress

Researchers at MIT and their colleagues are proposing a new design for electrodes that, based on the long-sought goal of using pure lithium metal as the anode, could lead to longer-lived batteries with higher energy densities. Thus, the whole solid battery can remain mechanically and chemically stable as it goes through its cycles of use.

Rechargeable membrane-less hydrogen bromine flow battery shows high power density

Green Car Congress

MIT researchers have engineered a new rechargeable, membrane-less hydrogen bromine laminar flow battery with high power density. In such a device, two liquids are pumped through a channel, undergoing electrochemical reactions between two electrodes to store or release energy. Credit: Braff et al. Click to enlarge.

MIT-led team devises new approach to designing solid ion conductors; implications for high-energy solid-state batteries

Green Car Congress

Researchers led by a team from MIT, with colleagues from Oak Ridge National Laboratory (ORNL), BMW Group, and Tokyo Institute of Technology have developed a fundamentally new approach to alter ion mobility and stability against oxidation of lithium ion conductors—a key component of rechargeable batteries—using lattice dynamics.

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

In contrast to previous flow batteries, the SSFC stores energy in suspensions of solid storage compounds to and from which charge transfer is accomplished via dilute yet percolating networks of nanoscale conductors. Source: Duduta et al. Click to enlarge. –3, in direct proportion to cell voltage.
