H2arvester is an array of solar panels, assembled on a light weight structure and supported on wheels, random moving or on rails. The solar energy can be processed into hydrogen (H2) and stored locally. Hydrogen stock is used locally when needed; the surplus will be delivered to third parties. The solution to convert the generated kWh directly into hydrogen ensures not just an autonomous functioning installation, but is also a solution for the need to balance the production and the use of generated energy while ensuring no electricity network reinforcements. Because the solar power plant is mobile, moving between the crops, H2arvester can be seen as extra crop in rotational cultivation that many arable farmers use. Also at dairy farmers, where H2arvesters move across the land between the livestock or across ditches, this is literally double use of agricultural land and generates extra income.
