“…, η T2G‐DC is an approximate value of the efficiency of the FC and HV battery system. η T2G‐DC is in line with the 43–51 % FC system efficiencies of FCEVs in driving mode at 10–15 % rated power reported in literature , , . The η T2G‐DC of 45 % (53 % on an LHV basis) is close to the reported Hyundai ix35 FCEV FC system DC efficiency of 46.8% (55.3 % on an LHV basis) .…”

“…To further reduce grid connection times, the inverter could also be switched on before connecting and turning on the FCEV, eliminating additional start‐up and grid frequency synchronization time from the inverter. Moreover, inductive discharging instead of conductive discharging (by cable) could reduce any further grid connection time , and likewise specialized FCEV V2G inverters with reduced reaction time and tailored Maximum Power Point Tracking or combining the V2G inverter with solar photo‐voltaic inverters .…”

The world's future energy supply will include intermittent renewable sources, such as solar and wind power. To guarantee reliability of supply, fast‐reacting, dispatchable and renewable back‐up power plants are required. One promising alternative is parked and grid‐connected hydrogen‐powered fuel cell electric vehicles (FCEVs) in “Vehicle‐to‐Grid“ systems. We modified a commercial FCEV and installed an external 9.5 kW three‐phase alternating current (AC) grid connection. Our experimental verification of this set‐up shows that FCEVs can be used for mobility as well as generating power when parked. Our experimental results demonstrate that present‐day grid‐connected FCEVs can respond to high load gradients in the range of –760 % s−1 to + 730 % s−1, due to the parallel connection of the high voltage battery and the fuel cell stack. Virtual power plants composed of multiple grid‐connected FCEVs could perform higher power gradients than existing fast‐reacting thermal power plants with typical power gradients of 1.67 % s−1. Hydrogen consumption in 9.5 kW AC grid‐connected mode was 0.55 kg h−1, resulting in a Tank‐To‐Grid‐AC efficiency of 43% on a higher heating value basis (51 % on a lower heating value basis). Direct current to alternating current efficiency was 95 %.

“…[18] 4 Usage -Modular Infrastructures Next to different possibilities for production and storage, there are also several approaches how to design the infrastructure depending on the application. Several parameters have to be considered when planning a hydrogen infrastructure [28][29][30][31][32]: -amount, pressure level, quality of hydrogen, -central or decentral application, electricity generation, operation strategies. Uneconomic operation of actual infrastructure concepts is mainly caused by high investment costs, high operating costs and the low system utilization in the market launch phase as well as the lack of flexibility in terms of expandability of the considered infrastructure.…”

A simulation tool called HYDRA to optimize individual hydrogen infrastructure layouts is presented. The different electrolyzer technologies, namely proton exchange membrane electrolysis, anion exchange membrane electrolysis, alkaline electrolysis, and solid oxide electrolysis, as well as hydrogen storage possibilities are described in more detail and evaluated. To illustrate the application opportunities of HYDRA, three project examples are discussed. The examples include central and decentral applications while taking the usage of hydrogen into account.
