Industrial green hydrogen could become a global commodity but local production is needed for transport uses

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.

Dutch grid company notifies further lengthy bottlenecks

The final 980 MW of transmission capacity in parts of the Friesland regional grid have been allocated to generation projects, and state-owned network business Tennet says bottlenecks could occur over the next seven years.

Universal electricity access by 2030 remains a distant dream

Energy efficiency, electrification of heating and transport, and the provision of clean cooking facilities are all going in the wrong direction as the Covid crisis deprived millions in sub-Saharan Africa of electricity use, according to a report by the IEA, IRENA, WHO, World Bank and UN Statistics Division.

Tennet begins internet-of-things grid balancing project

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.

IEA highlights solar’s dependence on Chinese copper processing

The sheer volume of new power lines which will be required to accommodate the rising tide of solar installations ensures copper has been included by the International Energy Agency on its list of minerals which must keep flowing if the energy transition is to stay on course. And it’s not production that’s the potential bottleneck.

China mandates energy storage as it sets 16.5% solar and wind target for 2025

The National Energy Administration has ordered grid companies to supply enough network connection points for all the solar and wind projects registered in 2019 and 2020, and said variable renewables should be supplying 11% of the nation’s electricity by the end of the year.

Solar and wind could provide half of 2040 power mix across 22 African nations

The International Renewable Energy Agency has combined energy infrastructure commitments across a huge swathe of the continent with hundreds of regional sites which offer rich solar and onshore wind potential, to determine what could be possible.

Special trade zones can help Africa’s energy transition

With investors often put off by a lack of supportive policy for renewables on the continent, the exceptions made to attract money to its economic trade zones might also prove more friendly to clean power infrastructure spending.

U.K. takes another tiny step to smart energy system

Energy regulator Ofgem has announced it aims to bring in market-wide half-hourly settlement across the retail electricity market – from October 2025. The long timescale reflects a sluggish attitude at an inconsistent regulator which appears to be planning an unpredictable route to net zero.

Add electric vehicles, not bulk transmission, for a low-cost, clean grid: UC Berkeley study

A 90% clean grid with a transition to EVs would achieve lower electricity costs than one without, the study shows. Transmission investments would mainly be spur lines to new renewable generation.
