Large-scale storage options for compressed hydrogen
Researchers from Finland and Sweden have reviewed different ways to store compressed gaseous hydrogen, including storage vessels, geological storage, and other underground options.
Baywa re wraps up major virtual PPA with Finnish packaging giant
The German clean power company and Huhtamaki have signed a 10-year deal that will ensure the construction of two solar farms in southern Spain with an aggregate generation capacity of around 135 MWp.
Low-bandgap GaInNAsSb solar cell for multi-junction architectures
Developed by researchers in Finland, the solar cell is intended to be used as part of lattice-matched multi-junction solar cells. It achieved a short-circuit current density of 15.2 mA/cm2 and external quantum efficiency of 0.79.
Massive solar project under development in Finland
The solar park will occupy 500ha of abandoned peatland in southern Finland. The project’s levelized cost of energy is estimated at less than €0.04/kWh.
Commission flags up €875m renewables project fund
A call for grant proposals has been promised this month, with the bloc’s executive yesterday firing the gun on a separate exercise related to cross-border EU energy infrastructure projects.
The Hydrogen Stream: Plans for $75bn, 50 GW green energy hub in Western Australia
Plus, as the European Commission prepares to present its ‘Fit for 55’ climate change package tomorrow, European companies are continuing to develop hydrogen plans, including Shell in Norway and Siemens in Germany.
‘Residential batteries are less profitable than selling excess power to the grid’
Although self-consumption of solar power is the optimal economic approach, the expense of household batteries at present outweighs the increased ability they offer to use electricity generated on the roof. Whether aggregated ‘virtual batteries’ offer better returns is an open question, due to lack of electricity company transparency.
Photovoltaics and geothermal heat pumps for domestic hot water heating
According to a new study from LUT University, domestic water heating costs may be reduced by combining rooftop PV with geothermal heat pumps. Scientists developed a control method to minimize these costs by taking advantage of cheap spot market electricity and maximized PV power generation, as well as considering heat demand, PV generation forecasts, and heat pump efficiency.
Best membrane for non-aqueous redox flow batteries
A Chinese-Finnish research team has identified composite membranes as the best future option for non-aqueous redox flow batteries.
Lithium saturation to make old batteries new
Scientists investigating the aging mechanisms affecting today’s lithium-ion batteries observed that the loss of lithium over time is one of the main causes of performance loss. With this in mind, they developed and tested a “relithiation” process that promises to eliminate much of the cost and complexity from recycling battery components and materials.
