LOHC Technologie - A Overview<\/h1><\/div>
LOHC is the storage solution of the future – we explain how it works.<\/div><\/div>[\/vc_column][\/vc_row][vc_row full_width=”stretch_row_content_no_spaces” bg_type=”image” parallax_style=”vcpb-default” bg_image_new=”id^995|url^https:\/\/h2-industries.com\/wp-content\/uploads\/2018\/11\/LOHC-Kopie.jpg|caption^null|alt^null|title^LOHC-Kopie|description^null” bg_img_attach=”fixed” css=”.vc_custom_1607615567759{padding-top: 50px !important;padding-bottom: 50px !important;}”][vc_column][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]The so-called Marlotherm is used as a Liquid Organic Hydrogen Carrier (LOHC), i.e. a liquid carrier medium for hydrogen. This oil-like liquid has been used as a heat transfer oil in a wide variety of applications and industries for years. Its ability to chemically bind hydrogen was discovered some time ago. By chemically binding the hydrogen, it can also be stored under normal conditions, contrary to current practice.<\/p>\n

This makes hydrogen handling not only safer, but also cheaper. With LOHC, the volatile hydrogen gas no longer needs to be cooled or compressed in a costly and energy-intensive manner in order to enable economical transport.<\/p>\n

One m\u00b3 LOHC enables the safe storage of 57 kg H2<\/sub>.[\/vc_column_text][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” bg_type=”image” parallax_style=”vcpb-default” bg_image_new=”id^995|url^https:\/\/h2-industries.com\/wp-content\/uploads\/2018\/11\/LOHC-Kopie.jpg|caption^null|alt^null|title^LOHC-Kopie|description^null” bg_img_attach=”fixed” css=”.vc_custom_1608457255308{padding-top: 50px !important;padding-bottom: 50px !important;}”][vc_column][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<\/p>\n

What can LOHC do?<\/h2>\n

With LOHC we have the possibility to compensate for temporal fluctuations and also local discrepancies between the generation and the demand of energy. This makes hydrogen easy to transport. For example, from northern Germany, where hydrogen can be produced using wind energy, to the south, where hydrogen can help reduce CO2<\/sub> emissions in refineries.<\/p>\n

Use at petrol stations or in ship drives is just as conceivable as use in the glass and cement industries. All areas in which hydrogen can be used can and will also benefit from LOHC as hydrogen storage.[\/vc_column_text][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” bg_type=”image” parallax_style=”vcpb-default” bg_image_new=”id^995|url^https:\/\/h2-industries.com\/wp-content\/uploads\/2018\/11\/LOHC-Kopie.jpg|caption^null|alt^null|title^LOHC-Kopie|description^null” bg_img_attach=”fixed” css=”.vc_custom_1608457262758{padding-top: 50px !important;padding-bottom: 50px !important;}”][vc_column][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<\/p>\n

How does LOHC work?<\/h2>\n

With pressures between 30 – 50 bar and catalysts specially developed for this application, the LOHC can be hydrogenated, i.e. hydrogen can be chemically bound. The resulting hydrogenated LOHC + can then be handled using the known infrastructure for fuels such as gasoline and diesel. The hydrogenation process is exothermic. The waste heat developed in this way can be used in other processes and thus increases the overall system efficiency.<\/p>\n

If the hydrogen is needed again, for example in chemical process plants, the steel industry or to supply fuel cells in order to use electrical energy, it can be extracted again from the LOHC +.<\/p>\n

In order to dehydrate the LOHC +, i.e. to release the hydrogen from the liquid again, the LOHC + passes through a dehydrogenation reactor, which contains the catalyst required for this process. In contrast to hydrogenation, dehydrogenation is an endothermic reaction. The necessary energy must therefore be added and can, for example, be made available within the system by using the hydrogen itself or provided by other, external heat sources.<\/p>\n

The dehydrogenated LOHC- can now be returned to the location of the hydrogenation and reloaded with hydrogen. The cycle is closed. The LOHC itself is not consumed, but reused many times over. The service life is also increased by the possibility of purification as soon as this becomes necessary after various (de) hydrogenation cycles.[\/vc_column_text][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” bg_type=”image” parallax_style=”vcpb-default” bg_image_new=”id^995|url^https:\/\/h2-industries.com\/wp-content\/uploads\/2018\/11\/LOHC-Kopie.jpg|caption^null|alt^null|title^LOHC-Kopie|description^null” bg_img_attach=”fixed” css=”.vc_custom_1608457262758{padding-top: 50px !important;padding-bottom: 50px !important;}”][vc_column][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<\/p>\n

What is LOHC?<\/h2>\n

LOHC is a heat-resistant oil with a capacity of 57 kg hydrogen per 1 m3<\/sup>. Hydrogen is chemically bound to and released from the LOHC in a chemical reaction on a catalyst.[\/vc_column_text][vc_row_inner content_placement=”middle”][vc_column_inner width=”1\/2″]

Storage and transportation of hydrogen<\/h2>\n

Storing and transporting hydrogen is one of the key challenges in the new global hydrogen economy. This is because hydrogen in its natural, gaseous form has the lowest density of all gases and is also highly flammable when mixed with the smallest amount of air. Storage of hydrogen as a liquid needs a lot of energy as it requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is \u2212252.8\u00b0C. Another storing and transportation option is the conversion of hydrogen into ammonia. To transport it ammonia gas is chilled and compressed to convert it from a gaseous to a liquid state. When released into the environment, liquid ammonia rapidly boils and returns to its gaseous state. Liquid ammonia expands to a gas at a ratio of 850:1. This means that a relatively small release of liquid ammonia can easily turn into a massive cloud of ammonia gas, evolving into catastrophic incidents. In addition, ammonia is flammable and is considered immediately dangerous to life and health. All of the above storage and transportation means require not only very careful handling, but also special design storage and transportation infrastructure.
\nLOHC as a carrier oil for hydrogen in contrary has many physicochemical similarities to diesel. Thus, LOHC can be handled in the existing infrastructure for liquid fuels, like oil tankers, trains or trucks, even existing oil-pipelines and storage facilities can be used. Due to their good energy storage densities, low cost, as well as unproblematic toxicology and handling, LOHC is one of the safest and most economical ways of storing and transporting hydrogen.[\/vc_column_text][vc_row_inner][vc_column_inner width=”1\/4″][vc_single_image image=”6946″ img_size=”large”][\/vc_column_inner][vc_column_inner width=”1\/4″][vc_single_image image=”6944″ img_size=”large”][\/vc_column_inner][vc_column_inner width=”1\/4″][vc_single_image image=”6942″ img_size=”large”][\/vc_column_inner][vc_column_inner width=”1\/4″][vc_single_image image=”6940″ img_size=”large”][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” bg_type=”image” parallax_style=”vcpb-default” bg_image_new=”id^995|url^https:\/\/h2-industries.com\/wp-content\/uploads\/2018\/11\/LOHC-Kopie.jpg|caption^null|alt^null|title^LOHC-Kopie|description^null” bg_img_attach=”fixed” css=”.vc_custom_1608457262758{padding-top: 50px !important;padding-bottom: 50px !important;}”][vc_column][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<\/p>\n

LOHC technology turns hydrogen into a secure power storage technology<\/h3>\n

H2<\/sub>-Industries solutions render the use of hydrogen gas in power storage technology simple, safe and effective making it possible to store, transport and release large quantities of electricity in an environmentally friendly, harmless way.[\/vc_column_text][\/vc_column][\/vc_row][vc_row bg_type=”bg_color” bg_color_value=”#ffffff”][vc_column css=”.vc_custom_1661843622838{background-color: #ffffff !important;}”]

H2<\/sub>-Industries technology is revolutionary and portends a huge advance in the electricity market.it Hydrogen has become a safe energy source from creation, storage, and transport to release.<\/p>\n

The LOHC technology is based on liquid carriers, that bind hydrogen chemically.\u00a0 Within H2<\/sub>\u2019s process, stored hydrogen is not volatile and cannot self-discharge. The LOHC can be charged and discharged only in combination with a catalyst, infusing and releasing hydrogen, as often as needed making it remarkably cost effective[\/vc_column_text][\/vc_column][\/vc_row][vc_row bg_type=”bg_color” css=”.vc_custom_1661852008405{padding-bottom: 70px !important;background-color: #ffffff !important;}” bg_color_value=”#ffffff”][vc_column][vc_single_image image=”3414″ img_size=”large” alignment=”center” onclick=”zoom” css=”.vc_custom_1609796589393{padding-bottom: -10px !important;}”][\/vc_column][\/vc_row][vc_row bg_type=”bg_color” css=”.vc_custom_1661852102841{padding-bottom: 70px !important;background-color: #ffffff !important;}” bg_color_value=”#f4fafe”][vc_column][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” bg_type=”image” parallax_style=”vcpb-default” bg_image_new=”id^995|url^https:\/\/h2-industries.com\/wp-content\/uploads\/2018\/11\/LOHC-Kopie.jpg|caption^null|alt^null|title^LOHC-Kopie|description^null” bg_img_attach=”fixed” css=”.vc_custom_1608457255308{padding-top: 50px !important;padding-bottom: 50px !important;}”][vc_column][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<\/p>\n

Hydrogenation of the LOHC<\/h3>\n

H2<\/sub>-Industries storage solutions work by charging (hydrogenation) and discharging (dehydrogenation) the LOHC. The charging and discharging are independent processes using proprietary catalyst technology<\/p>\n

The chemical process for storing hydrogen in the LOHC is performed under pressure. This allows an electrolyser to deliver the hydrogen directly, rendering additional energy-intensive compression unnecessary. The chemical reaction in which the hydrogen is bound in the LOHC takes place in a hydrogenation unit with a bed of porous noble metal catalysts and metered LOHC. This exothermic reaction heat releases heat, which is further utilised in downstream processes. Finally, the hydrogen-charged LOHC+ (perhydro-dibenzyltoluene) is pumped into the storage tank.<\/p>\n
