Curtailing solar photovoltaics is here to stay, overbuilding PV will become normal
As the penetration of variable renewable energy increases, curtailment of solar PV generation will only increase. Since curtailment will almost always be cheaper than investing in new transmission capacity or new grid-scale storage, curtailed energy should be rewarded, so that PV investment decisions can include curtailment as one of the flexibility options for grid operators.
A closer look at China’s Great Solar Wall
The US National Aeronautics and Space Administration (NASA) has published aerial images of the Great Solar Wall, China’s largest renewable energy project. The installation is expected to reach 100 GW of capacity by 2030.
Controlling water-to-water CO2 heat pump for optimal coefficient of performance
Scientists have designed a novel control approach for water-to-water heat pumps that use carbon dioxide. They relied on a virtual heat pump for their tests. The coefficient of performance (COE) improved by up to 14.6%.
Perovskite solar cell based on hole-selective interlayer achieves 26.39% efficiency
Researchers in China claim to have built a perovskite solar cell that can effictively reduce ion migration and offer superior stability. The device utilizes an ultrathin membrane made of a polymeric material known as PDTBT2T-FTBDT (D18), which reportedly offers conformal coverage on the surface of perovskite film due to its high fluidity.
Samsung launches monobloc air-to-water heat pumps
The Korean manufacturer said its new products are now available in the North American market and are suitable for multi-unit homes, apartments, new-builds and retrofits. The systems work with new AI technology and reportedly perform better when connected to a PV system.
NTPC allocates 1.2 GW of wind-solar hybrid capacity in India at $0.040/kWh
Adani Renewable Energy, Adyant Enersol (Datta Infra), Ampin Energy, Green Prairie Energy (EverGreen Power) and JSP Green (Jindal Renewables) have won in NTPC’s latest auction for 1.2 GW of wind-solar hybrid capacity in India.
Jordanian government promotes small scale solar
The new government of Jordan has been described by analysts as progressive on clean energy. Public support for solar has already been widespread, with tariffs for home systems encouraging people to adopt low-cost energy.
