Development and validation of a new magnetocaloric high-performance hydrogen liquefier prototype

HyLICAL将有助于达到基于磁制冷的8千瓦时/公斤的能源需求和120 K的液化成本。HyLICAL开发的磁热氢液化(MCHL)技术的实施提供了以下前景：i)5 TPD的小液化量的能效提高了20%；ii)在目标节能的基础上，资本支出(CAPEX)和运营费用(OPEX)至少减少了20%；iii)分散(本地)生产液氢(LH2)，从而减少了远距离分配和运输的需要；iv)将MCHL技术与离网配置的可再生能源(绿色氢气)生产氢气相耦合；v)整合到传统液化工厂，以提高其整体能源效率；六)氢气液化和液化氢储罐汽化管理工艺的应用。MCHL技术将能够分散生产绿色LH2，与化石来源的LH2竞争，如果当地有绿色能源(例如，生物基或来自可再生能源的电力)，还将进一步减少长途运输LH2的需要。我们将在项目结束时将MCHL技术的技术相关性级别从最初的TRL 3提高到TRL 5。这将通过将示范器的液化能力从目前的SOA(&lt；1公斤/天)大幅提高到接近100公斤/天来实现。正如电话会议中强调的那样，我们将证明，没有内在的限制阻碍MCHL技术扩大到适应100TPD以上的流量，从而满足重型移动部门和其他地方对大规模产能的需求。

HyLICAL will contribute to reaching an energy demand of 8 kWh/kg and a liquefaction cost of < 120 K) based on magnetic refrigeration. The implementation of the magnetocaloric hydrogen liquefaction (MCHL) technology developed in HyLICAL offers the following perspectives: i) Increased energy efficiency of >20% for small liquefaction volumes of 5 TPD; ii) Reduced capital expenditures (CAPEX) and operating expenses (OPEX) by at least 20% in addition to the targeted energy savings; iii) Decentralized (local) production of liquid hydrogen (LH2), thus reducing the need for distribution and transport across long distances; iv) Coupling of the MCHL technology to hydrogen production from renewables (green hydrogen) for off-grid configurations; v) Integration into conventional liquefaction plants to increase their overall energy efficiency; vi) Application of the process for the liquefaction of hydrogen and for boil-off management of LH2 tanks. The MCHL technology will enable the decentralized production of green LH2, in competition with LH2 from fossil sources, and will furthermore reduce the need to transport LH2 over large distances if there is a local green energy source available (e.g., bio-based or electricity from renewables). We will drive the Technology Relevance Level for MCHL technology from initially TRL 3 to TRL 5 at project end. This will be achieved by significantly increasing the liquefaction capacity of the demonstrator from the current SoA (<1 kg/day) to close to 100 kg/day. We will demonstrate that there are no intrinsic limitations that prevent the MCHL technology from being scaled up to suit flowrates above 100 TPD, as highlighted in the call, thus satisfying the need for large-scale production capacities needed in the heavy-duty mobility sector and elsewhere.
