The Hydrogen Stream: UK researching hydrogen storage nodes
Ofgem has awarded GBP 500,000 ($677,000) to a consortium led by National Gas and Gravitricity to develop a lined shaft system for storing up to 100 tons of green hydrogen underground. The six-month project aims to assess feasibility ahead of a potential demonstration in 2026.
High-frequency monitoring of floating PV
Researchers in Brazil have installed a vertical thermistor chain with six temperature loggers beneath a floating PV plant and at a nearby reference site. The system also recorded dissolved oxygen and photosynthetically active radiation to assess environmental impacts.
Shifting cloud patterns boost solar potential in the Amazon
In a new weekly update for pv magazine, Solcast, a DNV company, reports that solar irradiance levels across the Amazon Basin were 10% higher than the long-term average during April and May, reflecting a decadal trend towards drier conditions in the region.
Brazil solar imports slow as new China trade routes open
Brazil’s solar imports fell 33% to $722 million in the first four months of 2025 amid project delays and oversupply, as new trade routes began cutting costs and freight times to the country’s North and Northeast regions.
Entre a Geração Distribuída e o Mercado Livre de Energia
Com mais consumidores se tornando elegíveis a migrar para o mercado livre e a conexão das últimas usinas de geração distribuída no antigo modelo de compensação, como as empresas que atuam hoje com energia solar distribuída poderão se adaptar e continuar oferecendo soluções competitivas para seus clientes? Quais são as oportunidades e quais são os desafios da relação entre geração distribuída e o mercado livre?
Floating solar hits $65/MWh LCOE in Brazil, with up to 24 GW of potential
Floating solar could add 17 GW to 24 GW of capacity in Brazil, depending on pricing scenarios, while also reducing water evaporation by up to 50% and conserving water for hydroelectric generation, according to a new study.
Brazil generates 88% of power from renewables in 2024
Brazil’s electricity mix was 88% renewable in 2024, with wind and solar supplying about 24% of total demand, according to new data from state-owned energy agency Empresa de Pesquisa Energetica (EPE).
Improving perovskite solar cell durability via formamidinium cations
A team of São Paulo-based researchers have found incorporating formamidinium cations into methylammonium-based lead iodide perovskite films increases the durability of perovskite solar cells when fabricated and measured under ambient conditions.
A critical moment for Brazilian energy storage
A national procurement round for energy storage systems, planned in the second half of the year, is at risk of lengthy delay just as the grid operator is being forced to curtail large volumes of excess clean electricity.
Brazilian government to propose full opening of energy market by 2028 and end of discounts for renewables
The proposed reform of the electricity sector includes the creation of the supplier of last resort, possible flexibility for consumers without contracts and the end of TUST and TUSD discounts for renewable power plants. The plan also imposes a minimum load of 30 MW for self-production by equalization and determines changes in the cost sharing of the sector.
