Energy Storage

India will use its internal market to scale up hydrogen projects, with Germany as a possible export destination. As part of a broader strategy, the countries will collaborate on a financial and technological level on energy transition projects.

A Chinese research group has combined compressed CO2 with combined heating and power (CHP) units for renewable energy storage. The system has achieved a total energy efficiency of 35.96% and an energy storage density of 1.54 kWh/m3.

The Bulgarian Ministry of Energy has announced that a BGN 240 million ($134 million) rebate scheme is now open for applications from households seeking to install solar water heating systems and rooftop PV arrays, potentially coupled with battery energy storage systems.

Owners and operators of PV hybrid systems need to monitor and control system operation and performance, which generally involves the collection of big data sets. Data visualization techniques can simplify the monitoring and allow issues to be quickly recognized, says IEA-PVPS.

Sales of gas and oil heating systems are also increasing, however, as the current figures from the Federation of German Heating Industry show. Overall, the market grew by 38% to 306,500 new heaters sold. However, the German Renewable Energy Federation warns against postponing the country’s Building Energy Act requirements to 2027.

The Australian government has presented its 2023-2024 budget, with AUD 2 billion ($1.35 billion) to be invested in hydrogen, while Austria, Germany, and Italy said they have started moving forward on a southern hydrogen corridor from North Africa to Northern Europe.

The Serbian government is seeking a strategic partner to develop at least five PV plants with a cumulative capacity of 1 GW/1.2 GWh and at least 200 MW/400 MWh of battery energy storage. State power company Elektroprivreda Srbije (EPS) will own and operate the assets.

Construction has been completed on what is now the largest battery system in the Australian state of New South Wales. The 150 MW/300 MWh Riverina and Darlington Point energy storage systems are made up of three co-located units, owned by Federation Asset Management and Edify Energy.

Hyme Energy has awarded Semco Maritime an engineering, procurement, and construction (EPC) contract for services for the 1.6 MWh Molten Salts Storage (MOSS) Project in Esbjerg, Denmark. The long-duration energy storage plant will charge from the grid and be used to demonstrate and test the molten hydroxide storage technology in a practical setting.

The African Development Bank (AfDB) is seeking consultants to conduct technical due diligence for four storage-connected solar projects in Mauritius.
