Grids & Integration

Matt Harper, chief commercial officer of newly-merged British-Canadian vanadium redox flow battery business Invinity Energy Systems has spoken to pv magazine about the VS3-022 Battery Unit it is marketing for grid scale solar-plus-storage projects and why it may be a better bet than lithium-ion.

Researchers from Finland’s Lappeenranta University of Technology have assessed the economic advantages of a fully interconnected global network. They found that an international grid could contribute to a global LCOE of €52.50/MWh. The higher complexity of such a system, however, would only be marginally compensated by additional economic benefits.

The state-owned electric company, which has finally pivoted towards green energy, is developing a subsidy-free approach.

A thinktank has studied whether increased solar energy would contribute significantly to reducing the carbon footprint of the French and European electricity systems in an attempt to respond to a common French refrain the nation needs no further decarbonization of energy because it has nuclear power.

The losers in a world which no longer runs on fossil fuels are obvious but the dividend from shrugging off hydrocarbon dependency will be spread around most of the world so it is the nations which are winning the cleantech manufacturing and intellectual property race which appear best positioned for the future.

Perhaps it is not surprising a report co-produced by Europe’s solar industry places PV at the heart of a zero-carbon, mid-century energy system on the continent. However, the study does flesh out two out of three scenarios in which becoming carbon-neutral by 2050, or even 2040, could be possible.

Although the energy price recovered this week, ultra low levels driven by bumper solar power generation on a sunny weekend in Germany reportedly put further pressure on the business case for conventional energy.

Industry body SolarPower Europe hosted a webinar to consider how the global public health crisis will affect solar. While workers and materials are still available, industry experts are concerned about the state of the financial sector. Banks could become more conservative and raise the cost of capital for renewables projects.

With its sonnenVPP, German battery company Sonnen wants to improve the efficiency of virtual power plants which it says can offer primary balancing energy from houses with solar and storage and can operate up to 90% more cost-effectively.

German companies Uniper and Siemens will cooperate on joint projects to advance the use of green hydrogen and sector coupling. Conventional, gas-fired hydrogen production plants will be gradually transformed as part of the initiative.
