LOTTE, Sumitomo of Americas and Syzygy Plasmonics to companion on photocatalytic cracking of ammonia to supply hydrogen


Syzygy Plasmonics, LOTTE Chemical and LOTTE Advantageous Chemical (LOTTE Chemical HQ), and Sumitomo Company of Americas (SCOA) introduced a joint improvement settlement to check a photocatalytic reactor for clear hydrogen manufacturing. The reactor shall be put in and introduced on-line within the second half of 2023 at LOTTE Chemical HQ amenities in Ulsan, South Korea.

With the announcement of its 2030 Imaginative and prescient in Could 2022, LOTTE Chemical HQ outlined clear pathways and directives for decarbonization whereas concurrently reaching file income development. Amongst different climate-focused targets, the corporate is setting the stage to advance the hydrogen economic system in Korea. Plans embrace importing inexperienced ammonia that may be readily transported and saved earlier than it’s transformed into clear hydrogen with expectations of producing 1.2 million tons of hydrogen per yr domestically by 2030.

The standard thermal cracking of ammonia makes use of excessive warmth and stress to transform it to hydrogen gasoline. The warmth required to drive this course of is achieved by burning fossil fuels, making ammonia cracking extraordinarily carbon-intensive. Utilizing absolutely electrical reactors provides hydrogen producers a method to scale back or eradicate their reliance on combustion because the vitality supply for processing ammonia.

SCOA first invested in Syzygy in 2019 and since that point, the businesses have labored collectively to deploy its applied sciences. Syzygy has developed platform reactor expertise that makes use of mild from ultra-high-efficiency LEDs to energy chemical reactions by eradicating the necessity for warmth from burning gasoline, which is how conventional carbon-intensive chemical reactors are powered. (Earlier submit.)

The Syzygy photoreactor expertise is the fruits of greater than 30 years of plasmonics and nanotechnology analysis out of Rice College. A mixture of reactor design and photocatalytic nanoparticles permits light-driven chemical reactions with unprecedented effectivity, eliminating the necessity for combustion within the chemical response chain, and enabling the manufacturing of zero-emission hydrogen, inexperienced ammonia, and different foundational chemical substances.

Changing conventional thermal catalysts with photocatalysts not solely removes combustion, but additionally will increase effectivity. Every photocatalyst consists of tiny catalyst nanoparticles embedded within the floor of a bigger plasmonic nanoparticle; this two-part nanoparticle construction is known as an antenna-reactor.

Via plasmonics, the bigger nanoparticle transfers mild vitality to the tiny catalyst buildings and in so doing makes or breaks chemical bonds to trigger chemical reactions.

The antenna-reactor supplies extra environment friendly seize and switch of sunshine vitality to the reactive websites on the catalyst, successfully changing the necessity for thermal vitality from the combustion of fossil fuels with mild. This antenna-reactor idea may be utilized to develop photocatalysts for a number of chemical reactions, offering a path for changing thermocatalysis with photocatalysis all through the chemical worth chain.

The Syzygy P-DA photoreactor has the potential to supply clear hydrogen from inexperienced ammonia and renewable electrical energy. It breaks ammonia into hydrogen and nitrogen. This expertise has promise for producing zero-emissions hydrogen.


Syzygy’s course of provides a brand new method to electrify chemical manufacturing and eradicate emissions related to powering chemical processes. The corporate has demonstrated by intensive lab and pre-commercial-scale testing its capability to separate ammonia effectively and to supply hydrogen gasoline with out combustion.

Growth outcomes present the expertise won’t solely scale back the carbon footprint of hydrogen manufacturing, however it’s going to additionally assist scale back prices. The LOTTE Chemical HQ set up marks the primary time the expertise shall be deployed at a industrial scale.
