The hydrogen production is meant to be a feature while the batteries are fully charged. > "When electricity prices are high, then you can discharge this battery, but when the electricity price is low, you can charge the battery and make hydrogen," says Mulder. > "useful substances can be generated from it too, such as ammonia or methanol, which are typically easier to store and transport." > "...it became a better battery when it was used as an electrolyser too. They were also surprised to see how well the electrodes held up to the electrolysis, which can excessively tax and degrade more traditional batteries."
