Key challenges for underground hydrogen storage
An international research team has presented challenges and knowledge gaps in the implementation of large scale underground storage of hydrogen. The main issues associated with this technology relate to the fluid flow behavior of hydrogen in subsurface reservoirs, geochemical reactions caused by hydrogen injection, biotic reactions caused by excess hydrogen, and the geomechanical response of the subsurface to hydrogen storage.
LG Electronics offers hybrid system combining heat pump, PV and storage
The system generates electricity and heat for residential houses and small businesses. An integrated energy management system should guarantee maximum self-consumption of the solar power produced.
European joint venture wants to deploy 4 GW of PPA-linked solar across UK, Germany and the Netherlands
Ampyr Solar Europe, a new joint venture between Naga Solar, the AGP Group, and Hartree Partners, will develop ground-mounted photovoltaic projects in the three European countries. The solar parks will be financed through power purchase agreements with energy suppliers and businesses.
The Smarter E Europe postponed to July
The organizers of Intersolar and Ees Europe, in Munich, the largest photovoltaic and storage trade fairs in Europe, have decided to postpone the two events by six weeks. They hope that in the second half of the year there will be fewer restrictions and that the summer will have a dampening effect on the coronavirus pandemic.
Germany installed 4.88 GW of solar in 2020
The country saw around 525 MW of new PV capacity come online in December alone. The feed-in tariffs for PV systems not exceeding 750 kW in size were reduced by 1.4%.
European Commission approves further €2.9bn battery research project
Companies from a dozen EU member states will commit the public funds in a bid to come up with novel battery chemistries and production methods as well as recycling and circular economy innovation.
Axitec launches modular residential battery
The battery has a storage capacity ranging from 10 to 15 kWh and is already commercially available in Germany and Europe.
Silicon-carbide inverter for medium-voltage grids
Developed by scientists from German research institute Fraunhofer ISE, the silicon-carbide device claims 98.4% efficiency and could be used in utility-scale photovoltaic projects.
European scientists want to develop hybrid vanadium redox flow battery with supercapacitor
European scientists are designing a new type of redox flow storage system aimed at flexibly balancing power grids in the event of critical conditions. Funded by the EU, the research project is being coordinated by the Landshut University of Applied Sciences and runs until 2023.
Jenny Chase predicts up to 194 GW of solar this year
Falling module prices will help PV post another record year after an estimated 132 GW was installed worldwide in 2020, according to an energy transition investment trends report published by Bloomberg New Energy Finance.
