The most efficient way to produce sustainable hydrogen and oxygen from water


UHTP
(Ultra High Temperature Processes)
WaterSplitting

Our technology uses multiple patented ceramic components to split water into hydrogen and oxygen at high temperatures.

Operating at 2250°C, the technology uses heat, contrary to the electrical current in electrolysis, to split the water.

The gases are extracted separetely via patented Mixed Ionic Electronic Conducting (MIEC) ceramic filters, ensuring both high purity (>99.9%) as well as high safety conditions.

Proprietary heat exchangers enable the thermal recycling of the heat generated as well as of any available waste heat. This significantly improves the energy efficiency of the process.

ENERGY - EFFICIENT
Heat exchangers ensure partial recovery of the heat that resuls from the splitting of water into hydrogen and oxygen, serving to pre-heat the new incoming water. Furthermore, any waste heat available on-site can be re-used for further pre-heating.

Overall, this significantly reduces the overall energy input needed, making UHTP WaterSplitting at least 20% more energy efficient than electrolysis. If on-site waste heat is used, energy efficiency can even be improved up to ~38 KWh per kilo of hydrogen produced.

Moreover, forevery 1 kilo of hydrogen produced, 8 kilos of oxygen are also produced at no additional (energetic) cost.

SCALABLE
UHTP WaterSplitting uses proprietary ceramic materials and contains an electric heating unit, a ceramic reactor, ceramic filters, and ceramic heat exchangers. The ceramics are made from widely available raw materials and do not require rare earth metals, membranes or electrodes that could present a barrier to scale-up.

The ceramics industry is already well established and has a mature supply chain to accommodate rapid scale-up. Moreover, recent advances in ceramic material knowledge and supporting innovations developed by our partners throughout the supply chain will be crucial to drive fast capacity scale-up and industrialization of the UHTP WaterSplitting technology.

COST-EFFECTIVE
Re-using heat to improve energy efficiency brings significant cost advantages as energy costs can constitute up to 60% of hydrogen and oxygen production costs. Moreover, our system is based on ceramic components made from low-cost, widely available materials.

Altogether, these measures deliver more than 20% of lasting CAPEX and OPEX cost savings compared to current electrolysis technologies.

Similarly, the simultaneous production of high-purity oxygen presents multiple opportunities for extra revenue streams and cost spreading.



SAFE
The high temperatures that enable the splitting of water also ensure that the bonds between hydrogen and oxygen are weakened, reducing their ability to associate.

Our MIEC-filters can withstand these high temperatures and oxidizing atmosphere, ensuring a separate extraction of the oxygen and hydrogen at different temperatures.

As such, both gases are separated before extraction and cooling, which ensures high purity while eliminating any risk of explosive mixes forming. The entire process occurs at atmospheric pressure.

SUSTAINABLE
The splitting of water into hydrogen and oxygen through heat is completely green when powered with renewable energy.

Green Hydrogen is crucial to the decarbonization of various hard-to-abate sectors whereas high-purity oxygen is key to reducing other highly polluting emissions as NOx or SOx.

Moreover, UHTP WaterSplitting doesn’t require rare earth metals. Instead, we designed our system to be based on widely available and abundant materials. The secret is in the recipe.
