Scotland announces massive plan for heat pump deployment
The Scottish government wants to deploy renewable-powered heat pumps on at least 1 million homes and 50,000 non-domestic buildings by the end of this decade. For this purpose, it has created an advisory group and is now seeking to gather all potential stakeholders.
Indian utility seeks electrolyzer pilot projects
State-run power company NTPC wants to explore the feasibility of using hydrogen instead of diesel for back-up power and micro-grid application.
Photovoltaics and geothermal heat pumps for domestic hot water heating
According to a new study from LUT University, domestic water heating costs may be reduced by combining rooftop PV with geothermal heat pumps. Scientists developed a control method to minimize these costs by taking advantage of cheap spot market electricity and maximized PV power generation, as well as considering heat demand, PV generation forecasts, and heat pump efficiency.
Hydrogen-based storage system for residential applications
The system is based on a power-to-gas hydrogen technology and is intended to enable one and two-family homes to have an independent power supply throughout the year.
Greece to tender 700 MW of battery storage this year
Greece’s energy storage sector is heating up, with the government confirming plans to publish an energy storage policy framework and hold tenders for 700 MW of battery storage.
Green Cell unveils off-grid inverters for small residential buildings
Poland-based Green Cell is offering two versions of its new inverter, with power outputs of 1 kW and 3 kW. The inverters feature an efficiency of 90% and are recommended for small buildings such as cottages or year-round homes.
Cathode discovery ‘opens up new pathways’ for calcium-ion storage
Scientists in South Korea tested a new cathode material as part of a calcium-ion battery (CIB), achieving some impressive results. The material retained more than 90% of it initial capacity after 500 cycles, alongside some of the best performance results seen so far for this technology. The scientists say that this discovery opens up “an unexplored pathway toward the realization of stable and high-power cathodes in CIBs.”
Solarwatt, BMW launch new storage system for residential PV
The smallest of the storage units has a capacity of 4.8 kWh and an output of 1.5 kW. It can be expanded to eight battery modules in steps of 2.4 kWh and has a maximum of 57.6 kWh, and 6 kW, of power.
Northvolt gets cash boost to expand capacity of Swedish gigafactory to 60 GWh
The battery manufacturer is planning to raise $2.75 billion through a private placement and to use the funds to expand the capacity of its lithium-ion battery manufacturing site which is currently under construction in Sweden, from 40 GWh to 60 GWh.
Energy storage deployments slowed in the US in Q1, but the sector is on track for 3x growth in 2021, report says
Favorable federal tax policies and state regulatory reform could help the storage sector notch even higher rates of growth.
