The biomass production potential at temperate latitudes (56°N), and the quality of the biomass for energy production (anaerobic digestion to methane and direct combustion) were investigated for the green macroalgae, Ulva lactuca. The algae were cultivated in a land based facility demonstrating a production potential of 45T (TS) ha(-1) y(-1). Biogas production from fresh and macerated U. lactuca yielded up to 271 ml CH(4) g(-1) VS, which is in the range of the methane production from cattle manure and land based energy crops, such as grass-clover. Drying of the biomass resulted in a 5-9-fold increase in weight specific methane production compared to wet biomass. Ash and alkali contents are the main challenges in the use of U. lactuca for direct combustion. Application of a bio-refinery concept could increase the economical value of the U. lactuca biomass as well as improve its suitability for production of bioenergy.
对绿藻浒苔在温带地区（56°N）的生物量生产潜力，以及其用于能源生产（沼气转化为甲烷和直接燃烧）的生物质质量进行了研究。该藻类在陆基设施中进行培养，证明其具有 45T（TS）ha(-1) y(-1)的生产潜力。新鲜和粉碎的浒苔的沼气产量高达 271ml CH(4) g(-1) VS，与牛粪和基于土地的能源作物（如三叶草）的甲烷产量相当。与湿生物质相比，干燥后的生物质的单位重量甲烷产量增加了 5-9 倍。灰分和碱含量是浒苔直接燃烧应用的主要挑战。应用生物精炼概念可以提高浒苔生物质的经济价值，同时提高其生产生物能源的适用性。
