It can be used as feedstock, fuel or energy carrier and does not emit CO2<\/sub> when burnt, that is why you often hear about its high potential for decarbonizing our economy. But we don\u2019t want to decarbonize our atmosphere in total, we only want to come back to a CO2 <\/sub>ratio in the atmosphere like is was around 1900. What we really want to achieve is a defossilizing of our planet, which means to eliminate the burning of fossil fuels.<\/p>\n

In nature, we find it mostly in gaseous form (H2<\/sub>) and it is colorless. That is why, when you hear about \u201cwhite hydrogen\u201d, we refer to the naturally occurring one that might be (rarely) found in underground deposits. We don\u2019t have any viable strategy to use these deposits now, so\u00a0we apply different processes to generate it artificially<\/strong>.

Red Hydrogen from biomass<\/strong><\/h2>\n

Biomass can also be transformed\u00a0to produce hydrogen via gasification. Depending on the type of biomass but also on the use of carbon capture and storage technologies, the net carbon emissions can be lower than brown or grey hydrogen. If we capture the CO2 <\/sub>completely and if we don\u2019t have other emissions, it is like green hydrogen, but we call it red hydrogen.[\/vc_column_text][\/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_1610295825955{padding-top: 50px !important;padding-bottom: 50px !important;background-image: url(https:\/\/h2-industries.com\/wp-content\/uploads\/2018\/11\/LOHC-Kopie.jpg?id=995) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}”][vc_column][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” css=”.vc_custom_1610295743960{background-color: #c6c6c6 !important;}”][vc_column][vc_column_text]<\/p>\n

Grey: the most common one<\/strong><\/h2>\n

Most hydrogen nowadays comes from natural gas: it is bonded with carbon and can be separated from it via a process involving water called\u00a0\u201csteam reforming\u201d<\/strong>, but the excess carbon generates CO2<\/sub>. This hydrogen is called grey whenever the excess CO2<\/sub> is not captured. Grey hydrogen accounts for\u00a0most of the production today\u00a0and emits\u00a0about 9.3kg of CO2<\/sub> per kg of hydrogen production. Sometimes, hydrogen is referred to as \u201cgrey\u201d to indicate it was created from fossil fuels without capturing the greenhouse gases and the difference with brown or black hydrogen is just in the smaller amount of emissions generated in the process.[\/vc_column_text][\/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_1610295825955{padding-top: 50px !important;padding-bottom: 50px !important;background-image: url(https:\/\/h2-industries.com\/wp-content\/uploads\/2018\/11\/LOHC-Kopie.jpg?id=995) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}”][vc_column][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” css=”.vc_custom_1610295763853{background-color: rgba(30,83,188,0.67) !important;*background-color: rgb(30,83,188) !important;}”][vc_column][vc_column_text]<\/p>\n

Blue\u2026if you put the emissions underground<\/strong><\/h2>\n

Hydrogen is considered blue whenever the emission generated from the steam reforming process are captured and stored underground via industrial carbon capture and storage (CSS), so that it is not dispersed in the atmosphere. That is why Blue hydrogen is often considered a carbon neutral energy source, even though\u00a0\u201clow carbon\u201d\u00a0<\/strong>would be more accurate since\u00a0around 10-20% of the generated CO2<\/sub> cannot be captured.[\/vc_column_text][\/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_1610295825955{padding-top: 50px !important;padding-bottom: 50px !important;background-image: url(https:\/\/h2-industries.com\/wp-content\/uploads\/2018\/11\/LOHC-Kopie.jpg?id=995) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}”][vc_column][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” css=”.vc_custom_1610294271897{background-color: rgba(36,229,223,0.37) !important;*background-color: rgb(36,229,223) !important;}”][vc_column][vc_column_text]<\/p>\n

Turquoise: solid carbon as a by-product<\/strong><\/h2>\n

A new way of extracting hydrogen from natural gas is currently in experimentation phase. The gas can be decomposed at very high temperatures generating hydrogen and solid carbon thanks to a process called\u00a0methane pyrolysis<\/strong>. This hydrogen is then referred to as \u201cturquoise\u201d or low carbon-hydrogen.<\/p>\n

If the hydrogen is the result of a process called\u00a0water electrolysis<\/strong>\u00a0\u2013 that is using electricity to decompose water into hydrogen gas and oxygen, then we have a palette of 3 colors: pink, yellow and green. In this case, the full life-cycle emissions of this electricity-based hydrogen production, depends on how the electricity is generated.[\/vc_column_text][\/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_1610295825955{padding-top: 50px !important;padding-bottom: 50px !important;background-image: url(https:\/\/h2-industries.com\/wp-content\/uploads\/2018\/11\/LOHC-Kopie.jpg?id=995) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}”][vc_column][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” css=”.vc_custom_1610294347608{background-color: rgba(220,37,237,0.37) !important;*background-color: rgb(220,37,237) !important;}”][vc_column][vc_column_text]<\/p>\n

Pink: from nuclear energy<\/strong><\/h2>\n

Yellow: using a mix of whatever is available<\/strong><\/h2>\n

The colour yellow sometime indicates hydrogen produced via electrolysis through solar power, but often is also used to indicate that the electricity used for the electrolysis comes from mixed sources based on availability (from renewables to fossil fuels).[\/vc_column_text][\/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_1610295825955{padding-top: 50px !important;padding-bottom: 50px !important;background-image: url(https:\/\/h2-industries.com\/wp-content\/uploads\/2018\/11\/LOHC-Kopie.jpg?id=995) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}”][vc_column][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” css=”.vc_custom_1610295786774{background-color: rgba(21,229,18,0.75) !important;*background-color: rgb(21,229,18) !important;}”][vc_column][vc_column_text]<\/p>\n

Green: from renewables<\/strong><\/h2>\n

Green hydrogen, often also called \u201cclean hydrogen\u201d, produced using\u00a0electricity generated from renewables<\/strong>\u00a0and currently accounting for a small percentage of the overall hydrogen production. The European Commission intends to change that and built\u00a0an entire strategy to support hydrogen, highlighting its potential for a climate neutral Europe and putting it right at the center of the EU Green Deal (and its conspicuous budget).[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
