The direct coupling of electrolyzers with PV and wind power systems will become the cheapest forms of energy in many parts of Europe, according to Aurora Energy Research. February 28, 2022 Ralph Diermann Image: DLR, Wikimedia CommonsFrom pv magazine GermanyUK-based Aurora Energy Research has analyzed the cost of producing hydrogen from electrolyzers under four different business models in eight European countries.The report shows that green hydrogen could be produced in some European countries in 2030 for around €3/kg, thus reaching cost parity with blue hydrogen, which is produced from natural gas, with storage of the carbon dioxide released in the process. However, it cannot compete with gray hydrogen – for this, the costs would have to drop to around €2/kg.A comparison of different business models shows that the most competitive system design differs from country to country…
