Energy Source, a Brazilian battery specialist, is currently providing energy storage services with reused and recycled batteries. Battery recycling and related metals recovery are conducted separately, without the burning of materials.
Underwater gravity energy storage has been proposed as an ideal solution for weekly energy storage, by an international group of scientists. The novel technology is considered an alternative to pumped-hydro storage for coasts and islands without mountains that are located close to deep waters, and may also be interesting for PV if used to store green hydrogen.
The facility is expected to be located in the state of Ceará and to be powered by around 3.6 GW of wind and solar facilities located in the region. The project developer is Australia-based Enegix Energy.
A report by Finnish company Wärtsilä has estimated the potential impact if every dollar committed to a non-renewables energy sector recovery was instead funnelled to clean power.
Brazil now has 12 GW of underperforming hydropower capacity, according to U.S. researchers. Large-scale floating PV is an ideal solution to offset this shortfall, due to its high capacity factor, load correlation, and high potential output during periods of high demand.
While the full extent of the impact of the Covid-19 pandemics on the renewable energy market is yet to reveal itself, Norwegian consultancy Rystad Energy predicts new solar and wind projects will grind to a halt this year and experience a ripple effect in the years beyond as currencies across the globe continue to fall against the US dollar.
Researchers in Brazil have suggested using solar radiation databases and simulator software to scale PV-diesel mini-grid generators. The profiles of PV generation and mini-grid load demand are critical to finding the right balance, according to the academics.
