To Store or Not to Store: That is the Question

Green Car Congress

Typical daily grid demand. “ Why do you need energy storage on the grid, when the grid is full of power plants that generate all the energy that is needed? ” It would seem like a good question to ask and applies the same logic has been used for the past fifty years in determining grid strategy.

Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. —Rodney Keith, manager for the advanced concepts group working on the Brayton cycle technology. Maybe it’s just a pontoon bridge, but it’s definitely a bridge.

RMIT researchers develop concept “proton flow battery”

Green Car Congress

RMIT University (Australia) researchers have developed a concept battery based on storing protons produced by splitting water—a reversible fuel cell with integrated solid proton storage electrode. The concept integrates a composite metal hydride–nafion electrode into a reversible proton exchange membrane (PEM) fuel cell.

DOE announces $31M in funding to advance H2@Scale

Green Car Congress

The US Department of Energy announced up to $31 million in funding ( DE-FOA-0002022 ) to advance the H2@Scale concept. By producing hydrogen when power generation exceeds load, electrolyzers can reduce curtailment of renewables and contribute to grid stability. Earlier post.) Hydrogen produced from existing baseload (e.g.,

Siemens Energy, FFI and GeoPura developing prototype ammonia cracker to produce hydrogen

Green Car Congress

We have just 13 years to deliver a net-zero electricity grid for the UK. It can be used for storing large amounts of hydrogen in a liquid form that builds on existing global supply chain infrastructure. The technology could then be scaled up for future markets, including industry, heat, and grid-scale power generation.
