In June alone, new PV systems totaling 430 MW were connected to the German grid. The country’s cumulative operational PV capacity reached 55.3 GW at the end of June.
Italian scientists have assessed the technical potential of vapor compression heat pumps assisted by photovoltaic-thermal systems. They analyzed two main configurations of this combination describing the advantages and disadvantages of both solutions. The cheapest and easiest to deploy system is a single-source direct-expansion (DX) configuration for hot water for space heating or domestic hot water.
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 per kilowatt-hour and that a positive business case could be favored 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.
Necessity, as it’s said, is the mother of invention. For architect Samira Jama Aden, who plays a central role at Helmholtz-Zentrum Berlin’s BAIP consultancy for building-integrated photovoltaics (BIPV), the need for solar to be part of our built environment is becoming unavoidable. And for Aden, her mission is personal.
Plus there is news this week of a green hydrogen tie-up in India, plans for another German production facility, and of new hydrogen transport networks for Switzerland and the U.S.
The Swiss group has acquired an integrated solar roof system solution from an unidentified German engineering service provider for this purpose. The aim is grow this sector from a niche market.
Paris intends to secure 34 GW of solar, onshore wind and hydroelectric generation capacity by 2026 by offering generators premium payments – determined by competitive reverse-bidding among developers – to top-up the market electricity price.
