Add Q4_Duurzame biomassa voor de productie van waterstof (BO-43-021.01-023)

The green sector and the policymakers need a scientific evidence- based underpinning of the use of biomass (branch and top timber) as a sustainable raw material for bio-energy production.

The aim of the literature research is to visualize the sustainability effects of the use of top and branch timber and pruning wood for the production of hydrogen for the case Leisurelands

 

The use of wood for renewable energy is controversial. The occurrence of overuse is not questioned. Discussion is about the conditions on which overuse can be prevented. Due to climate changes, there is a high time pressure to realize new energy systems, by acting, innovating and learning. By investing now in small-scale, innovative hydrogen production with biomass (as a temporary raw material), the local introduction of the hydrogen economy can be promoted. It is expected that other sources for hydrogen will take over within decades. The required biomass infrastructure could maintains its value when timely next steps are taken towards green chemistry or other higher-value applications.

The raw material ‘branch and top wood’ plays an important role in the biological ecosystem. Important preconditions are a positive contribution to the reduction of C emissions, nutrients in balance of the soil and the preservation of biodiversity. The contribution to the reduction of C emissions must be viewed throughout the entire chain from harvest to production of green gas. Compared to the reference use of fossil fuels, a reduction of at least 70% must occur. This looks good for branch and topwood. The nutrient balance is primarily a focus on (poor) sandy soils. For forests on richer soils, sufficient nutrients are released from natural degradation of biomass. Biodiversity can be well protected by harvesting in the winter period and by working through the VBNE Nature Management Code of Conduct.
