“Capacity deferral is the primary source of storage value”

Big batteries derive most their value from replacing gas peaker plants and averting the installation of excessive amounts of transmission and generation infrastructure. However, batteries cannot replace all gas plants, MIT researchers found. From a holistic economics perspective, there is a certain share of storage that is considered cost-efficient. With battery costs declining, that share is constantly increasing.

Battery manufacturing capacity set to increase fourfold to 1.3 TWh by 2030

Analysts at Wood Mackenzie have looked at plans for the incoming decade and concluded that about 119 manufacturing sites will be up and running by 2030. China currently sits firmly in the driving seat, with Asia Pacific comprising 80% of global manufacturing capacity, but Europe is catching up.

Green hydrogen to reach price parity with grey hydrogen in 2030

IHS Markit’s latest report looks at a wave of new investments in large-scale projects. Economies of scale and technological improvements, as well as renewables deployment, could make green hydrogen price-competitive with grey and blue hydrogen.

Long read: Shadow boxing

The amount of non-uniform shading an array will experience determines the technology choices that can be made. However, it can be complicated to formulate more general rules for when to use what type of technology. Most would agree that module-level power electronics are better at handling non-uniform shading, but how do they handle the sun? A recently promoted study brought the discussion into sharp relief.

Affordable hydrogen-fueled flight possible in 2035

Hydrogen-fueled aviation has a realistic chance of helping the sector achieve climate goals, according to a European Union-commissioned study.

Leaked: EU hydrogen strategy eyes €140 billion turnover by 2030

The European Commission has sent the European Green Deal on its way and a preliminary version of its anticipated hydrogen strategy has been leaked. The plan does not lack ambition, as the EU seeks to assert tech leadership in green hydrogen through coordinated efforts across the value chain.

Solar-powered trees for cool spots in urban hot spots

A Japanese consortium has started producing solar-powered ‘urban furniture’. The result is a solar-plus-battery bench with cooling elements and vaporizers.

Evaluating battery chemistries for grid-level storage

Researchers in China have ranked some of the most commonly used battery chemistries according to parameters deemed important for grid-level storage. The team gave a score in each category and determined a winner – and it wasn’t lithium-ion.

Solar cells from space are on the way

A team at the U.S. National Renewable Energy Laboratory has come up with a new process that would reduce the production cost of highly expensive – and highly efficient – gallium arsenide cells.
