Provaris Energy has unveiled preliminary findings regarding its bulk hydrogen shipping concept, particularly focusing on meeting Europe's Renewable Energy Directive II (RED II) emissions standards. RED II, implemented in December 2018, aims to enhance the utilization of renewable energy sources and decrease greenhouse gas emissions within the European Union. The directive mandates that by 2030, a minimum of 32% of the EU's energy usage should originate from renewable sources. Key to RED II is the need for biofuels, bioliquids, and biomass fuels to exhibit significantly lower lifecycle greenhouse gas emissions compared to traditional fossil fuels. For hydrogen production, the emission benchmark is set at 28.2 grams of CO2 equivalent per megajoule (g CO2e/MJ) of hydrogen. Provaris collaborated with Wärtsilä to evaluate alternative propulsion configurations and conducted analyses on fuel efficiency and carbon emissions under various sailing conditions. Their estimations indicate emission levels of 7.6 g CO2e/ MJ H2 during a standard voyage speed of 13 knots on the 1,600 nautical mile roundtrip between Norway and Germany. These emissions projections were based on a suggested hybrid electric propulsion system employing modern 4-stroke LNG Dual Fuel generating units. Moreover, a prospective scenario modeled by Wärtsilä proposes integrating a 3,000kW hydrogen fuel cell into the propulsion system to further decrease emissions by 20 to 30%, dependent on operational profiles. Provaris' Chief Technical Officer, Per Roed, praised the effectiveness of the hybrid electric propulsion setup developed with Wärtsilä, emphasizing its current efficiency and adaptability to accommodate new fuels and technologies in the future.
