Scientists from the Fraunhofer Institute for Photo voltaic Power Programs ISE have developed a technical idea and design for a hydrogen era plant optimized for marine use. The “OffsH2ore” undertaking goals to outline a technically and economically optimized design for an built-in offshore hydrogen manufacturing plant utilizing proton trade membrane (PEM) electrolysis, together with the transport of compressed hydrogen fuel to land.
The facility provide for electrolysis comes from an offshore wind farm immediately linked to the five hundred MW electrolysis platform. The platform can produce as much as 50,000 tons of inexperienced hydrogen per 12 months. Recent water for the PEM electrolyser is obtained by desalinating seawater utilizing residual warmth from electrolysis.
The produced hydrogen is purified and dried, compressed to 500 bar, and transferred to a transport vessel that may carry as much as 400 tons of hydrogen from the platform to the mainland. This idea is unbiased of the hydrogen transport pipeline and affords flexibility within the alternative of location.
“The outcomes present that the manufacturing of hydrogen immediately within the sea with a PEM electrolyzer is technically and economically possible,” defined the scientists.
The undertaking is funded by the German Federal Ministry for Financial Affairs and Local weather Safety.
“With the idea offered by the consortium, speedy and large-scale implementation is practical,” the researchers mentioned.
The idea ensures the manufacturing of hydrogen with out territorial competitors.
“Offshore hydrogen manufacturing affords the chance to cowl your complete worth chain on the nationwide degree whereas breaking the growth of offshore wind energy and the growth of the grid,” mentioned Marius Holst, the undertaking coordinator.
To find out the price of hydrogen manufacturing, step one is to find out the cost-optimal capability of the offshore wind farm based mostly on the electrolysis capability of 500 MW. The minimal price of hydrogen manufacturing outcomes from wind energy of 602 MW. On this case, they quantity to five.92 EUR/kg which is slightly below 5,000 hours of full cost of electrolysis.
Hydrogen manufacturing prices enhance and full cost instances lower with decrease air capability. For instance, a wind farm with a capability of 490 MW ends in hydrogen manufacturing prices of €6.37 ($7.04)/kg and full load hours of about 4,225 h/a. On account of the low wind capability, the five hundred MW electrolysis is simply too giant and can’t function at a nominal load.
The consortium engaged on the undertaking contains Fraunhofer ISE, PNE AG as undertaking coordinator, SILICA Verfahrenstechnik GmbH, KONGSTEIN GmbH, and Wystrach GmbH.
Scientists from the College of Adelaide in Australia have lately found a approach to produce hydrogen immediately from untreated seawater. For this, they launched an acid layer of catalysts in situ.
