To achieve a net-zero and sustainable circular economy requires new solutions in utilising our waste sources. Often burnt in the field or buried as landfill, plant-based biomass from the forestry, farming and food sectors is a massive untapped resource for bioenergy production. Decarbonising industries with clean hydrogen will be key for achieving global net-zero targets. Hydrogen can provide a ‘cure-all’ solution to meet growing fuel and fertiliser needs; and provide a cost-competitive off-grid solution for electricity generation. However, hydrogen today first needs to be decarbonised as more than 99% is made from fossil-fuels. While efforts to make green hydrogen at scale using electrolysers and large-scale renewable sources are increasing, the greater challenge is getting low-cost hydrogen to the end-user. Transport and storage of hydrogen is complex and can more than triple the final cost of the hydrogen for the customer. Our solution simplifies this problem by safely producing low-cost hydrogen on-site and on-demand. Our robust biocatalyst solution is highly efficient at converting sugars into high-purity hydrogen from a wide variety of biomass sources. Compared to other renewable processes, our footprint of production is small; and we can make hydrogen 24-7 to fill the renewable energy gap.
