The uptake of EVs in the years ahead will add up to staggering battery capacity, mostly sitting idle on driveways. The two-way flow of electricity from EV batteries, known as vehicle to grid, could not only enable power systems to rely on intermittent renewables, but could also be the trump card for network operators to respond to grid disturbances. However, there are still a few catches to be worked out, as Marija Maisch explains.

Canada’s First Hydrogen and German consulting firm FEV are developing a hydrogen fueling station for remote locations where there are no electrical power grids available. Furthermore, Japan and Indonesia have started to cooperate on hydrogen and carbon capture technologies and the UK gas grid is set to start blending hydrogen around the country from next year.

Elsewhere, French renewable hydrogen startup Lhyfe has announced it is building an electrolyzer in eastern Germany, and Los Angeles-based Southern California Gas has launched a hydrogen-powered drone to monitor its gas grid.

Deployment in the building integrated PV segment is accelerating, and so too are the number of solar products available to architects and developers. And while BIPV had long been the segment in which an array of thin-film technologies could shine, they are now in increasingly stiff competition with crystalline silicon rivals.

Elsewhere, the ‘world’s first hydrogen racing truck’ has set out on this year’s Dakar Rally, with sponsorship from Saudi Aramco, and French hydrogen equipment business McPhy has been selected as preferred supplier for the GreenH2Atlantic project in Portugal.

Sharply rising PV module prices were one of the most notable developments in global solar markets in 2021. And while it dampened PV installations, with some projects delayed or canceled, the higher prices may point to a future where robust and stable demand leads to more sustainable pricing trends.

JinkoSolar says the collaboration could be the first-ever integration of next-generation N-type technology into solar hydrogen production. Meanwhile, Russia is reportedly ready to collaborate with the European Union on hydrogen energy projects, and Snam Group has signed a term sheet with the Torino Airport Management Company for the construction of a hydrogen-ready fuel cell system in cogeneration mode with a capacity of 1.2MW at Torino Airport.

Green hydrogen can play a vital role in decarbonizing 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.

Buildings are key to our daily lives and significantly impact our health and wellbeing. The majority also have substantial carbon footprints, employing heavy use of fossil fuels across their lifetimes, from their construction, use, and demolition phases. Thus, in Q4 2021, pv magazine’s UP Initiative focused on the role solar and energy storage can play in greening the world’s urban spaces.

Renewable energy and battery storage has racked up another banner year in 2021, according to end-of-year analysis from Rystad Energy. While there was growth across segments, residential solar has seen the most impressive gains, surpassing the commercial and industrial (C&I) segment for the year.
