Work begins on 145 MW floating solar plant in Indonesia

South-East Asia’s biggest floating PV installation is under construction by Masdar and Indonesian energy company PT PJB. The two companies secured a PPA for the project with state electricity company Perusahaan Listrik Negara (PLN) in January 2020. The agreed tariff is US$0.0581/kWh.

Ever heard of photovoltachromics, the new tech for solar windows?

Researchers in China have developed a smart solar window tech based on a photovoltachromic device that is able to achieve a high pristine transmittance and to be self-adaptable to control indoor brightness and temperature. The device was assembled via a full solution process in an architecture incorporating glass, a fluorine-doped tin oxide (FTO) layer, a perovskite-based PV cell, an electrochromic gel, another FTO layer, and glass.

Four-terminal heterojunction perovskite tandem solar cell with 30.09% efficiency

Developed by a Vietnamese-Korean research group, the complex PV device was built with a bottom bifacial crystalline silicon perovskite-filtered heterojunction sub-cell that is able to absorb all solar spectra in the short-wavelength range.

Novel plant design for agrivoltaics improves yield

Developed by Chinese researchers, the novel design methodology consists of utilising metal brackets as mounting structures, conventional solar panels, and a grooved glass plate placed between the solar panels. According to its creators, it ensures a farmer’s average income increases by 5.14 times, including the solar power generation business. A system built with this approach should cost around €715 (AU$1145) per kW installed.

Solar-powered large scale microbial food production

Producing nutrient-rich microbes with solar PV has the potential to produce more food with fewer resources, according to a German research group that modelled the large-scale production of microbial biomass by combining ground-mounted photovoltaics, air, water, and nutrients.

A closer look at liquid air energy storage

A British-Australian research team has assessed the potential of liquid air energy storage (LAES) for large scale application. The scientists estimate that these systems may currently be built at a cost between €300 and €600 (AU$480 to $960) per megawatt-hour and that a positive business case could be favoured by certain conditions, including a determined price structure in the energy market and the presence of a grid unable to support high levels of renewable energy penetration.

Work begins on 115 MW solar park in the Philippines

PH Renewables, Inc. (PHRI), a subsidiary of Global Business Power Corporation (GBP), which is itself part of the Philippines power utility Manila Electric Company (Meralco), has begun construction on a 115 MW solar park in Rizal, Luzon.

Sunseap announces 2.2 GW floating PV project at Indonesian water reservoir

If built, the project would be the world’s largest floating PV power plant and would reach the same capacity as the largest ground-mounted facility currently in operation.

China wants to test vanadium redox flow batteries

A 125 kW/500kWh storage unit will be tested by China’s National Photovoltaic and Energy Demonstration Experimental Center. The storage system will be provided by Canadian specialist VRB Energy.

Hydrogen-fired gas turbines vs. lithium-ion storage

According to a new study from the Massachusetts Institute of Technology, hydrogen-fired gas plants will compete with lithium-ion storage for seasonal storage and their competitiveness will strictly depend on the heat rate of the gas power plants they may replace.
