With strong government backing; a systems approach to development that views each component of hydrogen production and delivery as a whole; and growing demand, Australia could be on track for a commercially viable green hydrogen industry by 2030.

In May 2022, PV experts from around the world convened in Germany for the third Terawatt Workshop. Almost one year later, takeaways from discussions at the workshop – combined with a wide-ranging review of research on decarbonization pathways, energy demand projections, and the state of the art in PV technology – led to the conclusion that 75 TW of installed solar capacity by 2050 was a realistic global target. More than 50 leading PV industry figures recently outlined the opportunity and the challenges that solar will face in reaching this goal.

The deployment of a vanadium flow battery at a fire station run by Native Americans illustrates the role that the energy storage technology can play in ensuring that nobody is disadvantaged by the shift away from fossil fuels.

Brazil’s newly elected government, under Luiz Inácio “Lula” da Silva, will face energy-transition and decentralization issues during critically important years in the fight to curb climate change. Livia Neves reports from Rio de Janeiro.

Photovoltaics can wipe out 4.25 billion tons of carbon emissions every year this decade, according to the UN Intergovernmental Panel on Climate Change. Even so, the actions announced so far remain way short of what is needed, with capital flows to fossil fuels still greater than the cash directed toward combating climate change.

A report by Germany’s Energy Watch Group thinktank has said we would be better off sticking to coal and oil than switching to gas because emissions of methane, the most potent greenhouse gas, caused by gas extraction render any related carbon savings irrelevant.
