Hydrogen

MASH Makes the world’s cheapest green hydrogen in a decentralized manner that also sequesters carbon.

The need for advanced fuels such as Hydrogen, and particularly green H₂ is projected to grow greatly over the next decades, and many technologies are being developed to serve this market. MASH Makes’ Innovation aims to accelerate this development, unlocking the potential of sustainable fuels, and giving MASH’s clients access to the latest and greatest.

Using the TwoStage gasifier, the most efficient machine of its kind in the world, MASH is able to produce high-quality H₂ (up to 98% purity) from waste.

How do we do it?

The TwoStage Gasifier (MM-G101C): This gasifier design is widely acknowledged as the most efficient and well-documented market and the TwoStage gasification technology was developed at DTU Chemical Engineering by Ulrik Birk Henriksen. As indicated by its name, it features two separate stages – pyrolysis and gasification (see picture below). In separating the stages, a wealth of advantages is gained including high efficiency, flexibility and drastically reduced maintenance due to the elimination of the tar issue mentioned above.

Unlike many other sustainable energy solutions (solar, wind, boilers), the gasifier is extremely flexible and compact. The system is fully contained (aside from the feedstock storage area) in a 20-foot container, which can be easily moved if necessary.

The machine has a capacity of approx. 1.5 tonnes/day of feedstock that can have a moisture content of up to 58% (using an in-built steam dryer). The output is syngas (with a cold gas efficiency of >90%). Around 5-10% of the input remains as char – which is similar in properties to Activated Carbon.

Hydrogen production from the TwoStage gasifier essentially requires a separation unit in the form of a PSA (Pressure Swing Adsorber) and if required, a gas compressor. These bolt-ons are standard equipment that is also available in modules – thereby adhering to MASH Makes’ philosophy of compact design and on-site delivery of fuel products. The attractive net output of H₂ from the combined system is a result of the high concentration of H₂ in the output syngas from the TwoStage gasifier.

How do we do it?

Our primary customers for H₂ will be the transport sector and heavy industries, which currently contribute to a combined 14% of global GHG emissions and are difficult to (directly) decarbonize. Green H₂ from MASH’s innovation could help these to reduce their emissions by up to 34%:

Automotive transport: With hydrogen-powered vehicles already in the market, this is an obvious sector for MASH to supply to. The idea of hydrogen fueling stations using decentralized processing of waste/biomass residues via MASH gasifiers and separating+compressing H₂ is being looked into in detail. An installation like this would be a first-of-its-kind in the market, with a strong push for rollout in Japan, USA, EU as well as India.

Maritime sector: This sector has huge limitations with regards to electrification – and hence only ferries or short distance vessels can be electrified with the continuous development of battery technology. Batteries have insufficient capacity to power long-distance vessels. Fuel cells on the other hand are easily scalable for larger ships since individual cells can be stacked and most ships today can easily be retrofitted with fuel cells. DFDS, the world’s largest ferry operator and an investor in MASH, is a good example in the form of a major future off-taker for hydrogen for their upcoming H₂-powered vessels.

Iron and Steelmaking companies: The most crucial H₂ application would be to displace coking coal in blast furnace – which would deliver partial reductions and when coupled with MASH’s carbon removal and storage, would enable net-zero emissions for steelmaking.

Chemical companies: This sector currently consumes >40% of the total annual supply of grey hydrogen (from natural gas). Using MASH’s gasifiers and locally sourced biomass, this can be fully replaced by green H₂, thereby helping reduce the sector’s overall emissions. MASH is at advanced stage talks with Osaka Gas, a Japanese conglomerate primarily in the utility and chemicals sector. We will be jointly developing decentralized, in-situ hydrogen production solutions that would firstly help Osaka Gas to service their wide-ranging industrial customers; and subsequently for automotive transport. In the figure below, the sector-specific H₂ requirement is outlined, in order to reach a net-zero CO₂ emissions economy. With our strategy, we are already targeting the ones with the biggest potential.
