Researchers from Rensselaer Polytechnic Institute in the United States have developed a special class of materials for bulky calcium ions, providing pathways for their facile insertion into battery electrodes.

Terabase Energy has raised $44 million in a recent funding round to support digital and robotic platforms for the development of utility-scale solar power plants.

Mitsubishi Power Americas and Magnum Development are set to begin construction on a 300 GWh underground storage facility in the US state of Utah. It will consist of two caverns with capacities of 150 GWh, to store hydrogen generated by an adjacent 840 MW hydrogen-capable gas turbine combined cycle power plant.

The US Energy Information Administration expects 17.8 GW of solar capacity to be added to the grid by the end of this year.

A US-Chinese research group has built a perovskite solar cell with a hole-transporting material (HTM) based on conducting polyaniline (PANI) polymer. The device showed significantly higher efficiency than a reference solar cell relying on an HTM made of commonly used PEDOT:PSS.

Rob Barnett, a senior clean energy analyst for Bloomberg, forecasts a 30% increase in global PV deployment this year, and double-digit growth through 2025.

The US module level power electronics provider also introduced an installer certification course.

The PEM fuel cell test in New York demonstrated the viability of this technology at 3 MW, the first time at the scale of a backup generator at a data center. Meanwhile, a Spanish-Indian venture will develop up to 300 MW of installed green hydrogen production capacity in the Iberian Peninsula, and a Norwegian-German partnership aims to have a demo track powered by a fuel cell system on the road in mid-2023.

Peak solar production does not coincide with peak heating demand, and a team of researchers determined that meeting this demand with renewables alone will require massive deployment of renewables on top of existing fossil generation.

Solar module prices fell despite supply chain pressures, rising shipping costs, and increased materials costs.
