Plus, the Norwegian government is set to devote €2.5 million into a joint venture trying to develop liquid organic hydrogen carrier solutions for shipping by the middle of the decade.

Although self-consumption of solar power is the optimal economic approach, the expense of household batteries at present outweighs the increased ability they offer to use electricity generated on the roof. Whether aggregated ‘virtual batteries’ offer better returns is an open question, due to lack of electricity company transparency.

The NewMotion electric vehicle (EV) charging business owned by Anglo-Dutch energy giant Shell has become the first such entity to obtain a licence to provide grid balancing services in the Netherlands. Dutch grid company Tennet has licensed NewMotion to provide megawatt-scale balancing services to maintain grid frequency at 50 Hz by varying the rate at […]

Long distance, point-to-point transport of green hydrogen for industrial use can harness the cheap solar electricity available in some parts of the world but distributing the energy-storage gas to individual refueling stations, for vehicle fuel cell use, will likely have to depend on production nearby.

Household heat pumps, EV chargers and rooftop solar panels will be able to earn their owners benefits in return for helping to balance grid networks struggling to accommodate new solar and wind power generation.

The 98.7%-efficient device features six MPPT trackers and an overall input voltage range that is from 200 V to 1000 V.

The board of Xinyi Solar has announced it expects to have to install energy storage at its Chinese solar projects from July onwards, as a result of the recently launched five-year plan.

Instead of splurging €11 billion of EU cash on uneconomic new generation capacity, the Italian authorities–and electricity bill payers–would be better served investing in a mix of current clean power technologies which would include almost 17 GW more solar capacity.

Hydrogen transportation and submarine power lines have been compared by an international research team to find out which may be the cheapest option to connect for energy exchange regions separated by the sea. According to their findings, the hydrogen shipping alternative does not present very good prospects of applicability in the future, unless some disruptive technological breakthroughs are made. What makes compressed and liquified hydrogen ships still attractive, however, is that they can export energy almost anywhere, and that electrolysis and liquefaction plants are relatively easy to expand compared to marine cables.

Covid-19 border closures meant the first ‘active network management’ system was planned and commissioned for the Asian nation by the U.K. division of Saudi-owned smart grid specialist ZIV Automation.
