Green hydrogen can play a vital role in decarbonising the economy and enabling countries to reach net-zero emissions. The economics of producing green hydrogen from electrolysis are maturing as developers scramble to meet expected future demand. Everoze partner Nicolas Chouleur and Neoen hydrogen expert Sacha Lepoutre discuss a case study that shows how stacking different revenue streams could improve the economics of renewable energy projects.

Urban transportation is key to modern civilization. It has enabled humans to travel long distances and is one of the building blocks of industry and leisure. But it has come at a cost. In the first quarter of 2022, pv magazine’s UP Initiative will focus on the rise of e-mobility. We will examine urban transportation and the role electric vehicles, trains, and two- and three-wheelers can play in greening the electricity grid. In addition to technological innovation, we will also investigate market projections, the policies and infrastructure required, and the role solar and storage will play in taking this nascent industry full throttle.

The latest estimates of electricity generation costs in Australia have confirmed solar and wind continue to be the cheapest sources of new-build electricity generation, even when factoring in additional integration costs such as storage and new transmission infrastructure.

Australian green energy company Port Anthony Renewables’ oversubscribed capital raising exercise has put a fresh $3 million directly into its commercial scale hydrogen precinct ahead of a planned Australian Securities Exchange (ASX) listing next year. Meanwhile, Longi reportedly plans to build 1.5 GW of production capacity of electrolysers next year, up from 500 MW today.

Australia’s energy system was already a complex web, but it’s now transforming into the work of a labyrinth spider, which build tunnels so complicated and thick they look like white silk vortexes. You get the picture. Or you will from reading the Generator Insights 2021 report published today.

A U.S.-Israeli consortium is developing synchroinverters – inverters that mimic a synchronous generator and are able to actively respond to the grid’s frequency changes while stabilising the voltage. The new devices are expected to do this simultaneously and provide grid stability services in less than 16.67 milliseconds.

With Scottish company Smarter Grid Solutions having already seen its software deployed in the U.K., a pilot project in New York State has been a resounding success for a grid solution the NREL has predicted could unlock swathes of network capacity without the need for new power lines.

An Italian company has developed a system that can store energy from wind, solar and grid electricity by compressing and using CO2 without any emissions. The system draws CO2 from an inflatable atmospheric gas holder, stores it, and uses it to produce power again, when demand for stored energy arises.

Hitachi Energy has won Northern Territory Labor’s tender for the Darwin-Katherine ‘Big Battery’, which is expected to unlock more capacity for residential and industrial PV, generate cost savings of $9.8 million and pay for itself in approximately five years.

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.
