US scientists have improved the performance of intermediate-temperature electrolyzers based on protonic ceramic electrochemical cells. Germany and India have signed a hydrogen cooperation deal, while ArcelorMittal has tested the use of green hydrogen in the production of direct reduced iron at a steel plant in Canada.
The Canadian provincial government’s Green Economy Plan, launched in November 2020, envisages a 37.5% reduction in greenhouse gas emissions en route to net zero by mid century.
Prior to these amendments, Ontario’s net metering regulation required the customer to own or operate the renewable generation system to qualify as an eligible generator.
Building-integrated photovoltaics provider Mitrex said its system will provide St. Mary’s University student residence with a power-producing microgrid.
A floating, reverse-osmosis-based unit turns seawater into potable drinking water through the power of the sun and waves. Oneka developed the product, which requires no external electricity source and no land.
Scientists in Canada fabricated a perovskite solar cell based on an inverted structure that achieved 23.9% efficiency, and maintained 92% of its initial performance after 500 hours of accelerated aging tests. By carefully controlling the thickness of the perovskite layer, the group was also able to gain control of “quantum mechanics” properties such as the movement of electrons within the layer and the wavelengths of light absorbed.
Researchers in Canada have conducted a series of simulations to understand how spectrum splitters may raise the efficiency of two-terminal tandem solar cells and have found that efficiency gains may be of up to 6%. The proposed cell configuration was also found to be economically competitive.
