Hydrogen can be produced from various sources including biomass, renewables and LNG and possesses high energy density and long-time storage—said the minister, who recently took the test drive of a hydrogen fuel cell based car manufactured by Toyota Kirloskar.
The combination of pumped hydro with other storage technologies can increase renewables penetration, improve operational safety and reduce maintenance costs at large-scale hydropower plants, according to new research. The study also focuses on techniques to determine the optimal size of renewables-based pumped hydro storage systems. Costs for hybrid solar-pumped hydro projects currently range from $0.098/kWh to $1.36/kWh.
The pilot plants—installed at a temple and a school—work on a membrane-based electrodialysis technology to provide clean drinking water.
While it has often been referred to as “the future of PV” in recent years, discussions surrounding bifacial technology are now very much in the present. Modules are beginning to roll off production lines in significant numbers, and industry players are boasting of gigawatts of bifacial projects that are already installed or in the late stages of development. But it’s still early days for the technology, and there are questions to answer for it to achieve its full potential. pv magazine investigates the modeling and optimization of bifacial PV’s performance.
A U.S. research group has developed a metal-carbon-nanotube composite – MetZilla – which can be embedded in commercial, screen-printable silver pastes and is said to reduce the formation of hotspots in solar modules and to prolong panel lifespan. The composite metal contacts are also ‘self-healing’ as they are able to regain electrical continuity after cycles of complete electrical failure caused by extreme strain.
Spanish researchers have discovered a material said to offer radiative cooling and self-cleaning of devices which undergo critical heating during operation, such as PV panels. The thermal emitter enabled the scientists to lower the daytime temperature of silicon wafers by 14 degrees Celsius.
The Smart Energy Hub can operate in electrolysis mode to store renewable energy as hydrogen, or in fuel cell mode to produce electricity and heat from previously produced hydrogen or methane. Its developers are the French Alternative Energies and Atomic Energy Commission and start-up Sylfen.
Amtronics’ Tech City facility—constructed to a 75,000 sq.ft footprint—will use US firm Quantum Materials Corp’s technology to manufacture quantum dots and thin-film quantum dot solar cells.
Indigenisation of electric powertrain components and battery pack assembly could produce a 5.7% higher output value addition (US$ 2.7 billion) for the Indian auto industry in case of an electric vehicle (EV) transition.
