ARPA-E to award $27M for advanced nuclear reactor systems operational technology: GEMINA

Green Car Congress

Electric Power Research Institute: Build-to-Replace: A New Paradigm for Reducing Advanced Reactor O&M Costs - $999,464. X-energy: Advanced Operation & Maintenance Techniques Implemented in the Xe-100 Plant Digital Twin to Reduce Fixed O&M Cost - $6,000,000.

ARPA-E awarding up to $24M to 10 projects to support advanced nuclear power plants

Green Car Congress

As utilities have begun retiring older plants, however, comparatively high costs have made it difficult to justify building new nuclear power plants. In the building phase, cost savings may be realized through modular and advanced manufacturing techniques that bring most of the work to the factory instead to the construction site.

The Case for Nuclear Cargo Ships

Cars That Think

Researchers are considering three different types: a lead-cooled fast reactor, a uranium-fueled, helium-gas-cooled reactor, and a molten-salt-cooled reactor, shown here [below, at bottom]. The first was the American NS Savannah , built in the late 1950s at a cost of $46.9 One is a thorium-fueled molten-salt reactor.

Muons and ADNA proposing using accelerator-driven subcritical reactor for heat for production of synthetic fuels and chemicals

Green Car Congress

An initial proposed plant using GEM*STAR’s with the Fischer-Tropsch process would produce 70 million gallons of diesel fuel per year at an estimated cost of production of less than $2.00 The type of spallation target: lead, lead– bismuth, tungsten, molten salt, etc. Muons, Inc. , biomass or coal).

Li-Metal and Blue Solutions sign joint development and commercialization agreement to advance development of next-generation batteries

Green Car Congress

Existing commercial lithium metal production uses the electrolysis of a molten mixture of lithium chloride (45%) and potassium chloride (55%) at 400–450 °C in a low-carbon steel container suspended in a refractory brick chamber, which serves as the negative electrode in the electrolysis cell.

Researchers propose new aluminum–sulfur battery with molten-salt electrolyte; low-cost, rechargeable, fire-resistant, recyclable

Green Car Congress

An international team of researchers led by Quanguan Pang at Peking University and Donald Sadoway at MIT reports a bidirectional, rapidly charging aluminum–chalcogen battery operating with a molten-salt electrolyte composed of NaCl–KCl–AlCl 3. A paper on the work is published in Nature.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

The company is building these shipping container systems, which work like giant batteries that store energy as heat and pressurized air , rather than a chemical reaction (Cheesecake’s name is derived from a nerdy acronym for their technology.) Batteries have a powerful spigot, but that comes at the cost of a small tub.
