The Hydrogen Stream: Hydrogen buses less efficient than battery models
Italian researchers have compared the performance of hydrogen and electric buses in northern Italy, while DNV has released its guidelines to validate claims related to low-carbon renewable hydrogen and ammonia attributes.
New control technique for microgrid-connected PV systems
An international research group has applied for the first time integral backstepping control (IBC) as a control strategy for PV systems connected to microgrids. Through a series of simulations, the scientists found the new approach can provide better results than classic backstepping control (BC) and other techniques.
Lochinvar unveils heat pump to supply hot water at up to 70 C
Lochinvar has developed a heat pump with a hot water supply of up to 70 C, with a coefficient of performance (COP) of 5.5. The system is entirely cascadable, offering outputs ranging from 88 kW to 880 kW. It also includes 455 liters of hot water storage capacity and uses propane (R290) as a refrigerant.
Jaguar building large-scale storage system with second-life EV batteries
Jaguar Land Rover and Wykes Engineering are building a 2.5 MWh storage system with electric-vehicle batteries taken from Jaguar I-PACE cars. The large-scale system will store wind and solar at an undisclosed location in the United Kingdom.
Engie acquires Broad Reach Power
Engie has acquired 350 MW of operating storage assets and 880 MW of assets under construction from US battery specialist Broad Reach Power, with commissioning of the latter assets expected by the end of 2024.
