SeaH4 will produce biofuels from algae, using three well established technologies, namely • farming of algae • biogas production • gas processing This locally produced transport fuel is unaffected by global supply restrictions or currency fluctuations (as experienced currently) and the entire value chain and associated job creation remain in country. Without subsidies and due to economy of scale, our project is not only profitable but our sales price is on par with that of the fossil fuel industry, even excluding mitigation cost. This gap technology does not require any investment by the consumer and can make use of the existing distribution network. We enable a CO2 neutral operation of combustion engines, reducing the urgency of their replacement, diminishing the conundrum of financability and reducing the resistance to the transition. The project can be scaled up from its projected 15 million liters of bio diesel per year and duplicated in various countries around world.
