Driving down solar costs key to unlocking green hydrogen future
Jim Tyler, CEO of solar tech specialist Erthos, says that reducing the cost of solar electricity will be needed to unlock the next chapter of the energy transition: a green hydrogen economy.
The Hydrogen Stream: Water splitting with solar-to-hydrogen efficiency of 12%
A Japanese team is working on a solar water splitting system with a 12% solar-to-hydrogen efficiency, while UK researchers have identified the reason why graphene’s dense crystalline structure is much more permeable to protons.
Sun’Agri reveals agrivoltaics performance in heat waves
France’s Sun’Agri has revealed the results of a test showing how agrivoltaic installations effectively lower temperature and relative humidity during periods of drought.
Voltfang unveils outdoor storage system with recycled EV batteries
Germany’s Voltfang has developed outdoor stationary storage systems featuring recycled electric-vehicle batteries with capacities ranging from 33 kWh to 644 kWh.
Toshiba claims 16.6% efficiency for polymer film-based large-area perovskite solar module
Japanese electronics giant, Toshiba, is continuing to improve the performance of its perovskite solar cell technology.
3U launches heat pump for residential applications
Germany’s 3U Holding AG said its ThermCube heat pump is an ideal solution for new and existing detached and semi-detached houses with a total heat demand of between 6 kW and 11 kW. The new product has reportedly a heat output of 2.33 kW to 8.20 kW and a flow temperature of up to 70 C.
Decentralized heat pumps with district heating could cut opex by 24%
Researchers in Finland say that decentralized heat pumps could provide significant cost savings when selling surplus heat into district networks. However, they warned that capital expenditure remains high.
New DPP converter to improve yield in PV systems under permanent mismatch
Brazilian scientists have created a new hybrid converter topology based on differential power processing (DPP) that can help reduce power losses in PV systems under permanent mismatch conditions, as well as temporary ones caused by partial shading, dirt and snow. The converter consists of a hybrid topology that combines the PV-to-PV and PV-to-Bus architectures and reportedly solve some of the issues presented by both configurations.
Multi-day energy storage increases grid capacity by factor of 10
Form Energy has released a white paper that provides further evidence that multi-day energy storage, like its iron-air technology, can substantially reduce the costs for New York to achieve its ambitious decarbonization targets.
