According to the Economist, hydrogen technologies could eliminate 10% of today’s greenhouse-gas emissions by 2050.

Hydrogen is not easy to store as it needs to be under high pressures and not many materials are impermeable to hydrogen gas itself.

Hydrogen is used in several industrial applications today, Energy storage, Metall processing, Electronics, pharmaceutical. Leakage occur all through the value chains, while storing, transporting and using.

Graphmatech has a unique solution to massively reduce hydrogen gas emissions from storage and transport of hydrogen (Up to 80%) leading to reduced costs and greenhouse gas emission.

GMT technology corresponds to a reduction by 443 tons/year of hydrogen gas in 2030 and 1930 tons/year of hydrogen gas in 2034.

Some of the most promising cost saving features of Graphmatech’s technology are:

• Reducing hydrogen gas leakage by up to 80% in type IV CPV’s, allowing for more efficient storage and less loss of hydrogen over time.
• Enabling thinner liners by reducing hydrogen gas leakage and increasing liner strength.

Reducing pipe thickness at maintained hydrogen gas leakage rates, saving cost and material usage with maintained performance

Graphmatech’s solutions for decreased hydrogen permeation finds great use in both energy storage and transportation of hydrogen. The following sectors are of critical importance:

Hydrogen storage - Hydrogen storage infrastructure is expanding quickly across transport, industry, and energy systems. The build‑out is happening both within large‑scale storage, transport infrastructure, refueling networks, and integration into existing gas grids. Currently, 45 countries have hydrogen infrastructure in operation or under construction (H2-Stations - H2Stations.org). This transition to hydrogen-based energy requires materials which can withstand both leakage and mechanical load

Automotive (heavy trucks) – Hydrogen is emerging as one of the most serious alternatives to diesel for heavy‑duty trucks, especially where long range, fast refueling, and high payload matter. Hydrogen can enable the following key needs of heavy-duty trucks:

• Long driving range (as compared to battery driven trucks, hydrogen can provide significantly longer driving range before refuelling/charging).
• Fast refueling - Refueling time is similar to diesel: typically 5–15 minutes for a heavy truck.
• Ability to carry heavy loads - Battery‑Electric Trucks (BEVs) require very large battery packs (often 500–1000+ kWh) for long‑haul use, which can weigh several tonnes. Hydrogen Fuel Cell Trucks (FCEVs) store energy in compressed hydrogen tanks, which are far lighter than multi‑ton battery packs. This vastly increases the ability of the truck to carry heavy loads.
• Existing diesel trucks can be retrofitted to use H2 in their conventional combustion engine, reducing emissions at a faster pace and reducing the cost of lowering CO2 emissions.

In LIFE HYDROGRAPH project, the advantages of both FCEVs and H2-combustion as compared to BEVs will be further enhanced. Decreasing hydrogen leakage by up to 80%, enabling thinner and lighter constructions and longer driving range can enable the full potential of FCEVs.

Aviation and Unmanned Aerial Vehicles (UAV) -Hydrogen fuel source is becoming a major focus in aerospace and unmanned aerial vehicles (UAVs). The reasons for this focus are plenty:

• Hydrogen fuel cells emit only water, enabling zero emissions, clean operation and green aviation.
• Hydrogen has one of the highest gravimetric energy densities of any fuel which makes it relevant to replace currently used fossil fuels in aviation and directly addresses the “battery endurance bottleneck” in airborne transport.
• Longer flight times, greater range, and heavier payloads become possible.

This enables cost-effective and environmentally friendly aviation and UAVs.
Aviation is now regulated under several major CO₂‑related frameworks, at both the global and regional levels including ICAO’s CO₂ Standard, CORSIA, and the EU Emissions Trading System (EU ETS). The goal of these regulations are to decrease CO2 emissions and push manufacturers toward more fuel‑efficient aircraft technologies. Graphmatech’s solution can decrease hydrogen leakage from storage tanks by up to 80% and enable thinner and lighter constructions, supporting the development to improved fuel-efficiency.

UAVs find increasing use in agriculture, Emergency response and disaster management, infrastructure inspection and defence and security. With Graphmatech’s solutions, flight times can be further enhanced by the efficient reduction of hydrogen leakage without sacrificing weight of the construction.
