HYSTORSYSBringing you hydrogen compression solutions

HYMEHC

HYSTORSYS is a spin-off company from the Norwegian Institute for Energy Technology (IFE), and focuses on the use of metal hydrides for compression of hydrogen by means of thermal energy.

HYSTORSYS benefits from more than 40 years experience from IFE concerning the properties, synthesis and behaviour of hydrogen in solid materials – the metal hydrides (MH).

HYSTORSYS supplies thermal compressors for hydrogen with virtually no moving parts and practically no noise and vibrations. Exploiting waste heat, the compressor may be operated at almost no energy cost.

HYSTORSYS is developing metal hydride compressors with a very low maintenance level, and hence also low maintenance cost.

HYSTORSYS metal hydride compressors, named HYMEHC-x (x denoting Nm3/h H2, i.e., the hydrogen flow rate), will be available in capacity from 0.5 - 30 Nm3/h and pressures 100 - 200 bar (depending on inlet pressure).

– the thermal hydrogen compressors from HYSTORSYS – an innovative compressor solution featuring economical as well as technical advantages compared to other compressor designs.

Hydrogen is used in wide range of industries today. Hydrogen is considered as the most viable fuel alternative to petrol and diesel for road transport.Hydrogen is usually stored as compressed gas and in special cases as liquid hydrogen.Compression is typically achieved by means of mechanical compression, while liquefaction requires cooling to a temperature of -253°C.

About metal hydrides

The hydrogen molecules are split into atomic hydrogen at the metal surfaces

The atomic hydrogen gradually fills the metal lattice

Fully ”charged” the volumetric hydro-gen density of the MH-system is of the same order as for liquid hydrogen or better

Metal hydrides have the unique feature of adsorbing hydrogen when they are cooled and releasing hydrogen when they are heated. Moreover, the gas quality might actually improve during this process. HYSTORSYS is using these features in its new compressor design.Special alloys of metals will ensure optimal operation of the compressors in the selected temperature range.

The first full scale metal hydride hydrogen compressor, a HYMEHC-10 (10 Nm3/h), is in operation at the HyNor Lillestrøm hydrogen refuelling station in Norway (www.hynor-lillestrom.no).

A second compressor, a HYMEHC-5 (5 Nm3/h), iscurrently undergoing testing and validation at ourresearch facilities – providing valuable information tofurther improve design features.

In the unlikely event there is traces of impurities in theinlet hydrogen it will be removed by the metal hydride– in this way the compressor acts as a purification unit.This provides high quality hydrogen and guarantees ahigh purity level for required applications.

Furthermore, the HYMEHC hydrogen compressor from HYSTORSYS is flexible in production and design. The compressor can be made to specific customer needs with respect to size/capacity installations (floor, roof- or wall-mounted) and operated unattended.

The hydride compressor takes thermal energy from hot water for compression. Access to waste heat or geo-thermal water will give customers a big advantage as then energy consumption will be minimal compared to mechanical compressors. Thus it fits perfectly for many industries and/or in combination with reformers which usually operates at high temperatures.

To provide customers with an improved compressor quality with:

• Lower failure rates• High H2 purity• Lower operational costs

IndustryHydrogen is widely used in industry. Some have theirown on-site plants for hydrogen production, whilemany get their gas trucked in in cylinders fromindustrial gas companies. A majority of thesecustomers have regular deliveries of standard 200 bar / 50 litre hydrogen bottles (i.e., 10 Nm3 ofhydrogen).

As road transport of hydrogen becomes morechallenging, hydrogen consumers have started toexplore the option of securing their hydrogen supplyby establishing small on-site hydrogen generationplants. In order for such on-site hydrogen plants tobe efficient, a hydrogen backup/storage solutioninvolving hydrogen compression is needed.

HYSTORSYS metal hydride compressors can serve theindustrial gas companies as well as the industries andcompanies establishing their own on-site hydrogengeneration plants, potentially providing a solution for on-site bottling of hydrogen for backup. The HYMEHC is easily scalable from 0,5 Nm3 and up. Possible small compressors fit well for such backup solutions and/or other applications where small quantity is needed.

Hydrogen refuelling stationsHydrogen refuelling stations for cars and buses are agrowing market for hydrogen compressors. Hyundai, Toyota and Honda are all bringing vehicles to the market in the 2015-17 timeframe. Other car manufacturers will follow in the 2017 onwards timeframe. Hence, over thenext few decades hundreds or thousands of hydrogenstations are expected worldwide with the majority inEurope, USA, and Japan.

It’s our ambition is to supply compressors to this newmarket sector as well, specifically where waste heat is available, i.e. from H2 production.

HYSTORSYS AS is a Norwegian company owned byNorsk Innovasjonskapital III AS (managed byTeleventure Management), Prototech AS and JonEriksen, who is the company’s founder and ManagingDirector.Chairman of the board is Christopher Kloed (HonoraryMember of the Norwegian Hydrogen Forum) who hasmore than 20 years of working experience from thehydrogen sector.

PartnershipsThe company have maintained strong links to IFEwhich through their long-term research effortspossesses a world-leading expertise on hydrogensystems in general and metal hydrides in particular.HYSTORSYS subcontracts most of the production withcarefully selected partners, leaving the metal hydridetechnology, prototype development and design as thecorner stones of the in-house activity. The firstcompressors were built by Aquagas AB in Sweden.HYSTORSYS also has a co-operation arrangement withits owner Prototech and the hydrogen refuellingprovider HyNor Lillestrøm AS.

Partnering processAs the company expands, HYSTORSYS plan to partnerwith one or more companies/financial institutions thatcan complement HYSTORSYS both on the financial andtechnical side.
