Study finds direct seawater splitting has substantial drawbacks to conventional water splitting, offers almost no advantage

Green Car Congress

To meet this challenge and to satisfy the constant energy demand of society, electricity must be stored in times of overproduction to provide energy when little sunshine and wind is available. To store the green electricity in a highly scalable way, it must be converted into chemical energy. Energy Environ. Diess et al.

Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

Benson from Stanford University and Stanford’s Global Climate and Energy Project (GCEP) has quantified the energetic costs of 7 different grid-scale energy storage technologies over time. To quantify the long-term energetic costs, Barnhart and Benson came up with a new mathematical formula they dubbed ESOI, or energy stored on investment.

DOE issues RFI for hydrogen delivery R&D, targeting cost of $2-4 gge

Green Car Congress

The operating and maintenance cost of in-service compressors is exacerbated by the on/off cycling of the compressors resulting from a lack of station demand. The capital cost of the commercial hardware remains high due to low production volumes. Storage Cost Reduction Opportunities.

NREL study finds high-pressure hydrogen pipeline system could potentially make hydrogen cost-competitive with gasoline

Green Car Congress

A new study by a team at the National Renewable Energy Laboratory (NREL) concludes that a high-pressure, scalable, intra-city hydrogen pipeline system could improve the economics and logistics of hydrogen delivery, making it potentially cost-competitive with gasoline. kg—approximately equivalent to a gasoline cost of $2.7/gal

—Grey hydrogen gas, in other words—not a big win for the climate or the environment. The hydrogen gas produced in the summer will be stored and converted into electricity and heat in the winter. The hydrogen gas produced in the summer can be stored in an underground pressure vessel until winter. —Johan Martens.
