First crop of wastewater algae for biofuel

An EU-backed project in Spain has produced its first crop of algae to be used to manufacture biofuel. The project is so far the only one to use wastewater and its high nutrient levels to grow algae for biofuel. Bellona welcomes it as another initiative alongside its own Sahara Forest Project as an alternative to crop-based biofuels.

The All-gas project, located in the Southern Spanish town of Chiclana, is led by the world’s third largest water company, FCC Aqualia, along with five other organizations from Germany (Fraunhofer – Gesellschaft), Austria (BDI), the Netherlands (Feyecon y Hygear) and the UK (University of Southampton). Of the project’s initial €12 million development funding, €7.1 comes from the EU, en lieu of its FP7 program and its aim for 10% of energy used in transport to be from renewable resources by 2020. The initial fuel from the project is planned to run the city’s buses and garbage trucks.

Launched in 2011, the five-year All-gas project has completed its first of three planned stages in July. A 200 square meter facility has produced an algae harvest which shows a high energy potential, with a methane production capacity at between 200 and 300 liters of gas per kilogram of processed biomass. The project’s second stage constructing a one hectare prototype biomass plant is underway and the planned final stage would see a 10 hectare plant completed by 2016. 

Investing in algae as opposed to crops as the basis for biofuels is far more sustainable. Although direct CO2 emissions would be limited with any biofuel, indirect emissions and increased land-use would result from crop-based biofuels. Bellona therefore supports the development of 2nd generation biofuels (derived from wood residue and non-edible food) and 3rd generation biofuels (derived from algae).

This stand is also in line with recent EU initiatives. The European Parliament’s Environment and Food Safety committee (ENVI) in July passed a report calling for the limitation of crop-based biofuels. The plenary vote is expected on September 10.

The role of CCS in Germany’s climate toolbox: Bellona Deutschland’s statement in the Association Hearing

After years of inaction, Germany is working on its Carbon Management Strategy to resolve how CCS can play a role in climate action in industry. At the end of February, the Federal Ministry for Economic Affairs and Climate Action published first key points and a proposal to amend the law Kohlenstoffdioxid Speicherungsgesetz (KSpG). Bellona Deutschland, who was actively involved in the previous stakeholder dialogue submitted a statement in the association hearing.
