clean energy for the future

Hydro­gen at Wolftank

Hydro­gen is a very ver­sa­ti­le and non-pol­lu­ting energy carrier: its use pro­du­ces only water. It is also very light and has an extre­me­ly high gra­vi­metric energy density. Green hydro­gen is a “game changer” for decar­bo­niz­a­ti­on. Wolf­tank Group pro­vi­des long-stan­ding exper­ti­se, invests in R&D and builds the necessa­ry hydro­gen infra­st­ruc­tu­re for an emis­si­on-free future.

Hydro­gen is vir­tual­ly ever­y­whe­re, accoun­ting for an esti­ma­ted 75% of the mass of the entire uni­ver­se. Nevertheless, it only occurs in bound form, as a com­po­nent of larger che­mi­cal com­pounds such as water. Thus, hydro­gen must be pro­du­ced with an addi­tio­nal energy input and is the­re­fo­re a secon­da­ry energy carrier, com­pa­ra­ble to electri­ci­ty or heat. 

Hydro­gen is a very ver­sa­ti­le and non-pol­lu­ting energy vector: its use only pro­du­ces water. It is also very light and, at the same time, has an extre­me­ly high gra­vi­metric energy density: one kilo­gram of hydro­gen con­tains an enor­mous amount of energy, making it an effi­ci­ent and very light­weight energy carrier.

There are dif­fe­rent methods of hydro­gen pro­duc­tion, which use several primary energy sources. Depen­ding on the origin of the energy used in the process and the asso­cia­ted emis­si­ons, the hydro­gen pro­du­ced can be clas­si­fied into dif­fe­rent “colours”. The “green” or “rene­wa­ble” hydro­gen is the most inte­res­ting, since its manu­fac­tu­ring process does not cause direct carbon dioxide emis­si­ons, neither during pro­duc­tion nor during combustion. 

“Green” hydro­gen is pro­du­ced from rene­wa­ble energy sources and with low (or zero) asso­cia­ted pol­lutant emis­si­ons. The best ack­now­led­ged green hydro­gen pro­duc­tion method is the elec­tro­ly­sis of water, which con­sists of sepa­ra­ting the water’s mole­cu­le into its com­pon­ents (hydro­gen and oxygen) by app­ly­ing electric current in an elec­tro­che­mi­cal device called an electrolyser.

In the context of climate change, the Paris Agree­ment (2015) estab­lis­hed a global frame­work by limi­t­ing global warming to well below 2°C and con­ti­nuing efforts to limit it to 1.5°C. To achieve this target, science sug­gests that humans would need to neu­tra­li­ze their impact on the global climate by 2050 at the latest.

Fol­lowing this advice, the Euro­pean Union has deve­lo­ped its “Green Deal” roadmap, which aims to achieve climate neu­tra­li­ty in 2050. In Sep­tem­ber 2022, the Euro­pean Union took a his­to­ric decisi­on: It is estab­li­shing a EUR 3 billion Euro­pean Hydro­gen Bank that will further boost the hydro­gen market and develop it from a niche to a mass market.

Hydro­gen will be a “game changer” for Europe. Within this frame­work of necessa­ry decar­bo­ni­sa­ti­on, green hydro­gen plays a key role worldwide.

to 2024
Pro­duc­tion of hydro­gen from non-fossil (green) sources reaches a total capa­ci­ty of 6GW (1 million tons).
2025 to 2030
Incre­a­se total power to 40GW
within 2050

Sep­tem­ber 2022 announcement 

EU Hydro­gen Bank is created with an initial capital of € 3 billion to help the market, which needs to reach the EU’s pro­po­sed 2030 target of pro­du­cing 10 million tonnes of rene­wa­ble hydro­gen each year.
