hydrogen storage

Researchers in Spain has found that combining PV power generation with fuel cells and battery storage may help homes considerably reduce their levelized cost of energy. Their simulation reportedly demonstrated homes may also become completely self-sufficient.

Researchers in Australia have compared the technical and financial performances of a hydrogen battery storage system and a lithium-ion battery when coupled with rooftop PV. They evaluated two commercially available systems – LAVO and Tesla Powerwall 2 – and found that the lithium-ion battery provides better financial profits, whereas the hydrogen battery offers more battery lifespan for long duration of energy storage.

As the Oxford Institute for Energy Studies underlines the delays in hydrogen storage investments, a group of researchers have developed a cost-effective material to absorb hydrogen at non-cryogenic temperatures, which they consider optimal for fuel cell storage systems.

Researchers in Spain have studied the impact of hydrogen production and storage technologies in risk management for energy communities with internal price-tariff systems. They found that the optimal involvement in futures markets and spot markets will depend on a community’s risk aversion and self-sufficiency.

EntX has secured a license to explore salt deposits along the western side of the Eyre Peninsula in South Australia for the purpose of hydrogen storage.

Finnish and German researchers have assessed the role of seasonal hydrogen storage for PV prosumer households with a “least-cost” model at a global level up to 2050. They have found that seasonal hydrogen storage can only be expected in a niche, off-grid market.

Finnish researchers have studied different scenarios to convert a Nordic oil-heated townhouse into a carbon-neutral building. They dimensioned an off-grid PV-powered heat pump system using waste heat recovery from a hydrogen storage system and calculated its life-cycle cost. They concluded that the solution is less profitable than grid-connected systems.

Pusan National University researchers have found that hydrogen vaporization increases significantly as cryogenic tanks become emptier. The research sheds light on a key technology to transport hydrogen.

Gravitricity, an Edinburgh-based storage specialist, aims to develop the first full-scale demonstration of its underground hydrogen storage solution by working with structural engineering contractor VSL Systems UK.

Australia’s Energy Estate has signed a new agreement with Abergeldie, which designs vertical man-made caverns for hydrogen storage. The partnership will focus on a range of projects, including a 1.6 GW hydrogen network.
