US renewable energy farms outstrip 99% of coal plants economically – study
It is cheaper to build solar panels or cluster of wind turbines and connect them to the grid than to keep operating coal plants
“Coal is unequivocally more expensive than wind and solar resources, it’s just no longer cost competitive with renewables,”
On average, the marginal cost for the coal plants is $36 each megawatt hour, while new solar is about $24 each megawatt hour, or about a third cheaper.

RESILIENCE & BACK-UP POWER - e-Zinc
Resilience and back-up power requirements vary by customer and application, but in many cases necessitate energy supply over several days. This is an ideal application for e-Zinc’s technology because of its ability to provide multiple days of energy capacity. As an example, for a large residential or small commercial/industrial site in California, e-Zinc’s technology could […]
Is Repurposing EV Batteries for Grid Energy Storage a Sustainable Plan?
How sustainable is is the plan to reuse and recycle electric vehicle (EV) batteries in their second-life cycle?
75% of spent EV batteries will be reused in second-life by 2025,
EV batteries can retain up to two-thirds of their initial energy storage capacities in their second life.
Companies like General Motors (GM) and Nissan made way for turning second-life EV batteries into grid storage businesses in 2015. These manufacturers aren't the only companies dealing with EV battery reuse, with BMW having a few projects up their sleeves as well.
460,000 metric tons of lithium-ion batteries were to be recycled in 2020. To put that in perspective, we reclaimed batteries from less than a 5.6million EVs and got that weight. Yet, EVs only accounted for about 6% of global car sales in 2021.The 2020 recycling unit is obviously small when compared to the amount that would potentially be gotten from
20% of EVs to be sold worldwide by 2025. Accordingly, this yields a massive increase in EV batteries at their second life in the next two decades or less.The numbers keep surging, and an estimated value of 1.2million metric tons of EV batteries could be available for recycling in 2030
And much more is required to transport these dead batteries to recycling sites, which makes up about 40% of the recycling cost.
The First Commercial Sand-based Thermal Energy Storage in the World Is in Operation – BBC News Visited Polar Night Energy — Polar Night Energy
Polar Night Energy’s first commercial sand-based high temperature heat storage is now in operation at Vatajankoski power plant area. The heat storage, which has a hundred tons of sand inside, is producing low emission district heating to the city of Kankaanpää in Western Finland. BBC made a story ab
Storing renewables with high-rise elevators
Lift Energy Storage Technology is a proposed long-term storage solution that relies on elevators to bring solid masses to the tops of buildings in charging mode. It then lowers the same mass to produce electricity in discharge mode.

Turning high-rise buildings into batteries
With the rapid reduction in the costs of renewable energy generation, such as wind and solar power, there is a growing need for energy storage technologies to make sure that electricity supply and demand are balanced properly. IIASA researchers have come up with a new energy storage concept that could turn tall buildings into batteries to improve the power quality in urban settings.
