Fraunhofer ISE has presented the results of retrofit heat pump installations in multi-family homes in Germany. One demonstrator featured rooftop solar PV and a multi-source heat pump developed in partnership with Viessmann. It uses air and geothermal as heat sources.
SolarPower Europe says in a new report that households in Germany, Spain, and Italy can more than triple their savings by pairing PV with heat pumps. It said this combination helped families to save between 62% and 84% on their annual energy bills in 2022.
Pune-based Thermax has partnered with Australia’s Fortescue Future Industries to explore opportunities for the joint development of fully integrated green hydrogen projects for commercial and industrial customers in India. They also contemplate collaborating on electrolyzer and subsystem manufacturing facilities to support green energy projects in India.
Adani Group has committed to building 15 GW of renewable power projects in Andhra Pradesh, while Reliance announced its 10 GW solar plans for the state. Avaada, Greenko, Indosol, and ReNew have also pledged massive investments into the state’s renewables sector.
The Hyderabad-based developer will use the amount towards the capital expenditure of more than 25 GWh of pumped storage projects.
US engineers have built a scalable thermal energy storage prototype system that combines the best latent and sensible heat transfers. The technology, which is now market-ready after three years of testing, consists of engineered cementitious materials and thermosiphons in a combination that enables fast, efficient thermal performance at low cost.
Essar has formed Essar Energy Transition (EET) that will focus on investing in hydrogen, decarbonization, new energy infrastructure, and biofuels. EET plans to invest $3.6 billion in developing low-carbon energy transition projects in the UK and India over the next five years.
A joint study by IEEFA and Ember analysed 16 Indian states on their preparedness to shift away from fossil-fuel-based power, ability to incentivize greener market participation, power system’s reliability, and policies pushing for power sector decarbonization. It shows Karnataka and Gujarat fare well in progress towards clean electricity transition.
The pumped hydro storage plant, connected to the intra-state transmission system, is to be developed on a build-own-operate basis. Bidding closes on March 12.
Pumped hydro energy storage can be readily scaled to any required storage capacity at a known and affordable cost.
