Energy Storage

EleXsys Energy’s technology allows the controlled flow of excess energy from distributed rooftop-solar generators to help stabilize global grids as they increasingly transition to renewables. The world could feel the positives of mass transition to solar within five years.

Big plans for hydrogen development were announced this week in Germany, Namibia, Italy, Spain, Norway, Australia and the United States.

Dutch renewables company Photon Energy is teaming up with Australian technology provider and project developer RayGen Resources to develop a facility that will deliver 300 MW of solar generation and 3.6 GWh of energy storage. The technology used is claimed to have an LCOE of less than $0.072/kWh.

Lazard’s newly released Levelized Cost of Energy Analysis 15.0 and Storage 7.0 reports that solar and wind are the most competitive electricity sources in the US energy market. According to the investment bank’s 2021 study, gas combined cycle has the lowest LCOE of $0.045-$0.074/kWh among the conventional sources and that of coal and nuclear is $0.065-$0.152/kWh and $0.131-$0.204/kWh, respectively.

Developed by Italian dry bottom ash handling system provider Magaldi Power, the system produces green thermal energy — steam or hot air — which can be used directly in industrial plants or for the generation of electricity using steam turbines. The system consists of a blower, a fluidization air blowing system, a fluidization air suction system, an air filter and fan, an air pre-heater, and an integrated thermal energy storage module. Silica sands are the system’s storage media.

Australian energy storage specialist Redback Technologies has unveiled a newly expanded product range. It has added a series of grid-tied solar inverters and new beefed-up battery products to its line of modular storage systems for residential and commercial customers.

The US battery manufacturer entered the stationary storage business with a new product for residential customers. The lithium iron phosphate (LFP) battery is compatible with new or existing PV systems.

Proposed by Egyptian scientists, the proposed GIS technique considers a pumped-hydro project’s head and elevation difference, the penstock-length distance from the base plant, the site’s slopes and slope of the ground surface, the distance to the national grid and road networks, and the soil suitability. It also takes into account constraints such as land use and restrictions.

The French energy company blamed interconnection costs along with global supply chain and production issues, and tariff and trade disputes.

The lack of an incentive regime for battery projects and the like – whether a fixed feed-in tariff or market-driven contracts-for-difference program – is likely to see the COP26 host miss its 100%-clean-power-by-2035 commitment, according to K2 Management.
