Grids & Integration

Italian researchers have looked at the potential of thermal and electrical energy storage to improve self-consumption rates in buildings when coupled with PV-powered heat pumps. They have concluded that such an approach could yield self-consumption rates of more than 80%.

While electric companies in the Global North wrestle with how to keep the lights on as ever bigger solar and wind park capacities come online, developing-world utilities are experimenting with new ways of working and transforming the relationship between themselves and millions of new customers.

Italy’s Prysmian has finalized the deployment of a high-voltage direct current (HVDC) submarine transmission line spanning 1,400 km, connecting Denmark to the United Kingdom.

New research from Finland shows that the best season for rooftop PV generation in the Arctic is spring, and that the best tilt angle for rooftop systems is 28 degrees. It also showed that vertical PV installations perform better in winter.

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.

The Southern California Gas Company has agreed to a settlement of $175,000, without admitting fault, to cease claims that their gas is ‘renewable’. The company will also update its website to clarify that only 5% of its gas comes from renewable sources.

A group of researchers in Denmark has investigated how Carnot batteries may be used to store renewable energy in their home country and have found that these devices may provide a significant contribution only under a certain cost threshold.

The Ukrainian solar industry had hoped that a long-anticipated counter-offensive against the Russians would help reclaim PV assets on the eastern bank of the Dnipro River. The brutal reality is that the destruction of the Kakhovka dam has likely severely damaged solar plants in the affected territories, reports Ian Skarytovsky.

The typical volume of excess clean power wasted daily on the island has rocketed since last year. With a fossil fuel industry veteran heading the energy department after February’s presidential election, what prospect is there of a green transition?

New research has shown that Israel has the technical potential to deploy 172.5 GW of photovoltaics, of which 132.1 GW would be from conventional installations and 40 GW from agrivoltaics. If deployed, this full potential would require energy storage with a capacity of at least 500 GWh and strong development of vehicle-to-grid technologies.
