Markets & Policy

New research from Stanford University professor Mark Jacobson seeks to remove any doubts about grid stability in a world powered entirely by renewable energy. The latest study models 100% wind water and solar powered grids across the United States, finding no risk of blackouts in any region and also broad benefits in cost reduction, job creation and land use.

The hype surrounding green hydrogen is real, but does the cost-reduction outlook for its production technologies live up to it? Christian Roselund looks at the technology, transportation, application and enabling policies behind the promising green energy carrier.

China is once again the focus of attention across the global solar PV industry. The country’s manufacturers have had a turbulent 2021, but domestic demand remains strong, particularly from the booming residential rooftop segment. Despite the supply challenges, China will likely reach 50 GW this year and possibly even 100 GW next year. Given the dynamic market and policy landscape, pv magazine publisher Eckhart K. Gouras recently caught up with long-time China solar expert Frank Haugwitz, the founder of the Asia Europe Clean Energy (Solar) Advisory (AECEA).

Large-scale renewable energy generators, including wind and solar PV farms will ramp up to 140 GW from the current 15 GW, more than doubling every decade to 2050 while rooftop solar is expected to increase from 15 GW to 70 GW over the same period as the “accelerating” transformation of Australia’s energy sector continues.

Gujarat-based solar manufacturer Solex plans to have 1 GW of cell and 3.7 GW of module capacity operational in 2023.

The impression of another big battery being installed on the site of one of Australia’s recently decommissioned “coal clunkers” was lost on few. Battery system provider Fluence says the Hazelwood Battery Energy Storage System’s business case was bolstered by recent reforms and new technology to take advantage of rapidly changing wholesale electricity market dynamics.

The 300 MW / 450 MWh Victorian big battery in Geelong has today commenced operation. In spite of fire breaking out during commissioning in July, the battery has been delivered in record time, taking less than a year to build and begin operations.

The International Energy Agency said the four nations are on track to contribute 85% of the 18 GW of global renewables capacity which is set to be dedicated to green hydrogen production by 2026. Elsewhere, the Port of Valencia has unveiled a plan to install a green hydrogen supply station in the new year.

Two of Australia’s most prominent energy players, AGL Energy and Fortescue Future Industries, today announced plans to repurpose infrastructure at AGL’s Hunter Valley coal stations to turn them into green hydrogen hubs.

A consortium including Australian concentrated solar thermal power company Vast Solar has filed to patent a new tank design for thermal energy storage systems. The new design, it says, substantially mitigates the risk of tank failures which have been identified as one of the key shortcomings of the economical storage technology.
