Conceived for the storage of residential and large scale renewable energy, the device has a rated power of over 150mW/cm², an energy density exceeding 40Wh/L, and a power density of 72.5mW/cm². The battery was built with an anode made of inexpensive viologen and its cost, according to its creators, may be lower than $100/kWh.

Microinverter provider Enphase has signed a deal with Swell Energy to participate in distributed virtual power plants in California, New York and Hawaii.

As research into non-rare metal catalysts continues, companies in northwest Europe are working on an offshore green hydrogen demonstration project, the first European data center to run on green hydrogen, and on hydrogen-based solutions for container transport. Meanwhile, European institutions are prepping for stronger hydrogen collaboration with Africa.

Recent BloombergNEF research shows that corporations procured a record 31GW of renewable energy in 2021, and LevelTen Energy says that growth occurred despite more than a year of price increases.

New research from Sweden showed that financing conditions and the choice of location are crucial factors in reducing the levelized cost of energy for utility scale solar parks built without subsidies in the Scandinavian country. According to the researchers, the project with the lowest LCOE in Sweden, of €0.02737/kWh, is a plant with an expected lifetime of 45 years, a 2% annual degradation rate, capex of €703,758 per megawatt installed, a yearly fixed operations and maintenance cost of €11,277 per megawatt, and a nominal weighted average cost of capital per annum of 0.2%.

Greenko Group has agreed to provide Ayana with 6GWh of pumped-hydro storage capacity from its project in the Indian state of Andhra Pradesh.

The Parque Solar Zonda project is expected to be built by Yacimientos Petrolíferos Fiscales (YPF) in three 100 MW phases and to require a total surface of 300 hectares.

Australia has hit a historic milestone – it has reached 25GW of installed solar capacity. As the Australian PV Institute noted on Monday, that’s more solar per capita than anywhere else in the world.

The project is relying on Sineng’s 3.15MW turnkey battery stations EH-3150-HA-UD 35 and is the first phase of a 300MW/600MWh that the Chinese state-owned power company China Three Gorges Corporation is building in China’s Shandong province.

Researchers from the United States have investigated how fuel cells and electrolyzers may be able to operate under intermittent availability provided by both wind and solar and have found that an affordable hydrogen-based system for seasonal energy storage could be achieved at a hydrogen price lower than $3, produced from inexpensive renewable electricity at $0.02/kWh.
