Project description
Advanced water splitting technology to boost hydrogen production from solar energy
Using sunlight and water, which are both abundant on Earth, to create hydrogen fuel has great potential for creating a clean and renewable energy source. Hydrogen and oxygen are produced by thermochemical water splitting at high temperatures from concentrated solar power. The EU-funded HySelect project aims to develop an efficient and cost-effective method of hydrogen production based on a two-step water splitting cycle. This two-step process will include sulphuric acid decomposition into sulphur dioxide at a high temperature and sulphur dioxide electrolysis at a lower temperature (50-80 °C). HySelect will demonstrate two full-scale plant prototype devices for both parts of the hybrid sulphur cycle.
Objective
HySelect will demonstrate the production of hydrogen (H2) by splitting water via concentrated solar technologies (CST) with an attractive efficiency and cost, through the hybrid sulphur cycle (HyS). The HyS consists of two central steps: the high temperature -yet below-900C -decomposition of sulphuric acid forming sulphur dioxide (SO2) and the subsequent low temperature (50-80C) SO2 depolarised electrolysis (SDE) of water to produce H2. HySelect will introduce, develop and operate under real conditions a complete H2 production chain focusing on two innovative, full scale plant prototype core devices for both steps of the HyS cycle: an allothermally heated, spatially decoupled from a centrifugal particle solar receiver, sulphuric acid decomposition-sulphur trioxide splitting (SAD-STS) reactor and a sulphur dioxide depolarized electrolyser (SDE) without expensive Platinum Group Metals (PGMs). Furthermore, a heat recovery system will be integrated to exploit the temperature difference within the cycle and boost the overall process efficiency. In the course of the work, non-critical materials and catalysts will be developed, qualified and integrated into the plant scale prototype units for both the acid splitting reactor and the SDE unit. Experimental work will be accompanied by component modelling and overall process simulation and culminate with a demonstration of the complete process integrating its key units of a 750kWth centrifugal particle receiver, a hot particles storage system, a 250kWth SAD-STS and a 100kWe SDE into a pilot plant. Testing for a period of at least 6 months in a large-scale solar tower, driven with smart operation and control strategies, will establish the HySelect targeted efficiency and costs. Finally, an overall process evaluation will be carried out in order to assess the technical and economic prospects of the HySelect technology, directly linked to the know-how and developments of the sulphuric acid and water electrolysers industries.
