The heat storage tank is 45 m high and has a capacity of 56 million liters. It will store district heating water at a temperature of 98 C and, according to Vattenfall, will use heat produced with renewable electricity coming from the grid.

Hurricane-force wind gusts hit New England during a late-October storm, damaging at least one rooftop solar array and leading Commercial Solar Guy to offer a few pointers.

Through the procurement exercise, the Danish authorities want to allocate 429 MW of renewable energy capacity. The tender will be open to PV, wind, hydro and wave power projects.

The Danish Energy Agency has granted permission, to two power-to-X specialists, for the development of innovative projects without having to comply with the country’s energy legislation. This exemption is part of an upcoming pilot scheme to support new clean energy technologies, including green hydrogen.

BP, Iberdrola and Enagás will power a 20 MW electrolyzer with 40 MW of solar in Spain. Automotive manufacturers Hyundai, Stellantis, Toyota and BMW sent a letter to European Commission Vice-President Frans Timmermans asking to support the continued expansion of a 700 bar hydrogen refuelling network in Europe.

Furthermore, Michelin said it wants to become a world leader in hydrogen fuel cell systems and ScottishPower aims to build a green hydrogen plant at a wind power complex. Moreover, a study led by scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory suggested new strategies to design perovskite materials to speed up the oxygen evolution reaction (OER), a process that frees up molecular oxygen from water and is key for hydrogen production.

The Institute for Solar Energy Research Hamelin (ISFH) is testing if renewables can cover 80% of electricity and heating demand combined in some town districts in southern Germany.

The tender is aimed at procuring 2 GW of capacity in response to the chronic short-term electricity supply gap that is affecting the country and its mining sector. The South African government has selected three LNG projects that may secure around 60% of the awarded capacity and several renewable energy projects including solar, wind and storage. The procurement exercise attracted a lowest bid of $ 0.0998/kWh.

EDF and Oceanus plan to build a pumped hydro storage station and a desalination system powered by wind and solar. The system will use saltwater to produce hydropower during periods of high demand, while producing affordable freshwater.

A new, nature-inspired algorithm has been applied by scientists in Egypt and Saudi Arabia to optimize the production of green hydrogen via solar and wind power generation. The proposed energy system consists of PV and wind power generation, a water electrolyzer, a tank of hydrogen gas, a fuel cell, and an inverter that brings the generated electricity to final consumers.
