“…In the present study, H 2 demand is modeled according to the requirements of two different consumers, namely FCAM (agricultural machinery) and FCMV (minivan). FCAM H 2 demand was estimated for a cereal farm in Sweden according to the model described by Lagnelöv et al (2020) based on dynamic discrete-event simulation with embedded state-based logic for decision making. The simulated farm encompassed 300ha equally distributed between barley, oats, spring wheat, and winter wheat crops.…”

“…The simulated farm encompassed 300ha equally distributed between barley, oats, spring wheat, and winter wheat crops. The model used a conventional cropping system with work beginning in mid-March and ending at the start of November (Lagnelöv et al, 2020). One of the main aspects of this model is a workability control based on weather conditions and soil moisture content, which considered the water balance model described in (Witney, 1988) and tested by (Nilsson and Hansson, 2001).…”

“…While the latter may be restricted to large farming operations (minimum megawatt-scale equipment), H 2 as fuel could potentially be used in small-and mid-size farms since it has been successfully implemented at the kilowatt-scale in industrial applications such as welding and brazing, material handling vehicles (e.g., forklifts and airport towing trucks) as well as for mobility (e.g., golf cart and longrange passenger cars) (Allman et al, 2017;Apostolou et al, 2019). Thanks to its higher energy density compared to lithium-ion batteries, H 2 -based fuel cell agricultural machinery (FCAM) may be preferred to manned battery-electric since agricultural operations often require continuous hours of heavy fieldwork (NHA, 2012;Wu et al, 2019;Lagnelöv et al, 2020). In addition, during the conversion of electricity to H 2 via water electrolysis, oxygen (O 2 ) and low-temperature waste heat (WH) at 60-90°C are produced which could be valorized (Buttler and Spliethoff, 2018).…”

Techno-Economic Assessment of Demand-Driven Small-Scale Green Hydrogen Production for Low Carbon Agriculture in Sweden

Wind power coupled to hydrogen (H2) production is an interesting strategy to reduce power curtailment and to provide clean fuel for decarbonizing agricultural activities. However, such implementation is challenging for several reasons, including uncertainties in wind power availability, seasonalities in agricultural fuel demand, capital-intensive gas storage systems, and high specific investment costs of small-scale electrolysers. To investigate whether on-site H2 production could be a feasible alternative to conventional diesel farming, a model was built for dynamic simulations of H2 production from wind power driven by the fuel demand of a cereal farm located on the island of Gotland, Sweden. Different cases and technological scenarios were considered to assess the effects of future developments, H2 end-use, as well as production scale on the levelised- and farmers’ equivalent annual costs. In a single-farm application, H2 production costs varied between 21.20–14.82 €/kg. By sharing a power-to-H2 facility among four different farms of 300-ha each, the specific investment costs could be significantly decreased, resulting in 28% lower H2 production costs than when facilities are not shared. By including delivery vans as additional H2 consumers in each farm, costs of H2 production decreased by 35% due to the higher production scale and more distributed demand. However, in all cases and technological scenarios assessed, projected diesel price in retailers was cheaper than H2. Nevertheless, revenues from leasing the land to wind power developers could make H2 a more attractive option even in single-farm applications as early as 2020. Without such revenues, H2 is more competitive than diesel where power-to-H2 plants are shared by at least two farms, if technological developments predicted for 2030 come true. Also, out of 20 different cases assessed, nine of them showed a carbon abatement cost lower than the current carbon tax in Sweden of 110 €/tCO2, which demonstrate the potential of power-to-H2 as an effective strategy to decarbonize agricultural systems.

“…In previous studies by our research group assessing the production capacity and economic impact of autonomous battery electric tractors through simulations [17,18], they were shown to have a comparable work rate and lower total annual costs for certain system topographies. One of the main arguments for changing from a few large diesel-powered tractors to multiple smaller battery electric tractors is the potential environmental benefit in replacing diesel with electricity that has a smaller environmental footprint.…”

There is an increased interest for battery electric vehicles in multiple sectors, including agriculture. The potential for lowered environmental impact is one of the key factors, but there exists a knowledge gap between the environmental impact of on-road vehicles and agricultural work machinery. In this study, a life cycle assessment was performed on two smaller, self-driving battery electric tractors, and the results were compared to those of a conventional tractor for eleven midpoint characterisation factors, three damage categories and one weighted single score. The results showed that compared to the conventional tractor, the battery electric tractor had a higher impact in all categories during the production phase, with battery production being a majority contributor. However, over the entire life cycle, it had a lower impact in the weighted single score (−72%) and all three damage categories; human health (−74%), ecosystem impact (−47%) and resource scarcity (−67%). The global warming potential over the life cycle of the battery electric tractor was 102 kg CO2eq ha−1 y−1 compared to 293 kg CO2eq ha−1 y−1 for the conventional system. For the global warming potential category, the use phase was the most influential and the fuel used was the single most important factor.
