State of the Art - High Level Introduction

15

Current refueling protocols are insufficient for use in heavy duty applications, as they do not support:

  • Fills to the required amount of hydrogen

Most refueling protocols are limited to 10 or 30kg.

  • Fills in the required speed / high enough transfer rates of hydrogen to the applications

The required flow rates for HD applications are just not supported by current protocols

  • The meeting of cost targets for hydrogen to customer

Current refueling protocols do not support the required cost decrease path to diesel parity by forcing the station to over-design

  • Clear but flexible criteria on how to fill an application with hydrogen

Either the protocols are too prescriptive or non-informative, such as with SAE-J-2601/2

WP4 simulations: to help establishing protocols for HD refuelling

Structure

To launch the different simulations, these elements are mandatory (should be defined in WP2 and 3):

  • Composite tank characteristics
  • HRS characteristics
  • Refuelling protocol basics

The different simulations (Air Liquide and Engie) needed:

  • Fast simulations (SOFIL / HYFIL) for the different refuelling

conditions

  • CFD calculations in some specific cases (outside the

applicability range of engineering models) Validation of some modelling cases with experimental results in WP5

3 governing factors identified:

  • Amount of energy stored => Range
  • Time to refuel
  • Cost equivalency
  • If these can be equal or better compared

to current (fossil) use cases, barriers to adaptation will be low Applications in comparison:

  • HD long haul trucks
  • Inland shipping vessels (4 types)
  • Passenger trains (regional transport)
  • Mainline locomotive
  • Hydrogen transport systems
  • Garbage trucks

*it is likely such a system would have at least two independent tank systems, therefore half the flowrate can be assumed. **it is currently unsure whether these applications are feasible to refuel with gaseous hydrogen in their current operational scheme. It is well possible that options can be found to shorten the distances between fills or switch to alternative modes of supplying molecules, such as swappable containers, LH2 or other alternatives.

State of the Art

52

  • Currently used refuelling protocols
  • LD: mostly SAE J 2601 (1-10kg)
  • LD: some proprietary protocols for type 3 CHSS vehicles, e.g. Symbio
  • MD: JPEC-S-0003 (up to 30kg)
  • Bus + train applications: boundary conditions from SAE J2601/2 (not a full protocol) with individual ramp

rates and configurations of the HRS

  • -> creates application specific issues when applications change
  • LH2 and CCH2 will be analyzed later – focus on GH2

Gap Analysis of existing protocols

53

  • Shortcomings of current protocols:

 Static, very conservative tables (unforgiving in operation)  Very narrow control margins on Temperature and Pressure (cost drivers)  Stacking of tolerances (e.g. Worst case tank model + hot/coald soak + most unfavourable heat capacities of components + ...)  Data on end temperatures of fills  High cost of precooling - often to unnecessarily high levels of accuracy and depth  Structure means that any other concept than a station with HP-buffer tanks (e.g. Direct compression) is almost impossible  Above limits add up and will not let us achieve fossil cost parity for larger applications  Limitations to 60g/s or 120g/s peak flow will not let us achieve refueling time parity for larger applications

Recommendations for future protocols

54

  • No tank size classes
  • No precooling classes (like MC method)
  • No worst case tank model
  • Ideally, target application is known well enough to predict a near optimal fill
  • Ideally, limitations of the station (e.g. Capacity, remaing stock, etc. are taken into account)
  • Ideally, customer can choose to fill for 5, 10, 50€ or so

WP2 recognizes need to fill CHSS with 0- ~8000kg in the mid term – protocol should be usable for all of

  • these. Most pressing need is to verify range most typically used for HD LH trucks and city buses, but protocol

should conceptually be capable of delivering the full range

Gap Analysis of existing Hardware

67

  • Nozzles and receptacles:

The most commonly used hardware is H70 LD with up to 60g/s flow

Buses and trains mostly use H35HF with up to 120 g/s

  • Neither of these give enough flowrate to refuel the applications

as needed

  • It is necessary to develop appropriate hardware (nozzles,

receptacles, breakaways, hoses, control valves, flow meters, etc.) for applications in the required ranges

  • It is highly recommended to create an intercompatibility

between pressure ranges to allow access to low cost

  • hydrogen. It is proposed to introduce a „ultra high flow“ class of

components, similar to LD:

Hardware Development

  • Scope of Work

1. Procure prototypes – RFP circulated globally to potential suppliers in 2019 2. Test – based on existing standards with some modifications

1.

High Flow Target: 180 g/s (10.8 kg/min)

2.

H70 vehicles with onboard storage sizes 30-100kg 3. Publish – publish results and receptacle design establishing prior art and preventing patents and subsequent licensing of receptacle design 4. Standardize – submit receptacle design to global standard associated with fueling hardware: create new documents where necessary
