Exploring biogas stakeholder interaction in the Netherlands: An Agent Based Modeling approach to explore location specific biogas system performance under different scenarios

Biogas networks can reduce CO2 emissions by replacing natural gas consumption with biogas consumption. This means that biogas production can contribute to the Dutch targets to reduce CO2 emissions by 20% and increase renewable energy production to 16% by 2020 compared to 1990 levels. It is unclear how the biogas infrastructure system will...

A supply demand model for exploration of the future of the Dutch gas sector

Import dependency and the extent of renewable gas production are two outcomes of interest concerning the future of gas supply in the Netherlands. Due to the complexity of internal mechanisms and uncertainties associated with the natural gas production, the production of renewable gases, and the demand for gas, the future of these two outcomes of...

Anaerobic dynamic membrane bioreactors for high strength wastewater treatment

A laboratory scale external anaerobic dynamic membrane bioreactor (AnDMBR) treating high strength wastewater was operated to assess the effect of gas sparging velocity and organic loading rate on removal efficiency and dynamic membrane (DM) filtration characteristics. An increase in gas sparging velocity (GSV) results in a decrease in DM...

Autogenerative high pressure digestion: Future potentials and constraints

Biogas generated in waste (water) treatment facilities is increasingly regarded as an important source of renewable energy. However, generally, the CH4 content in biogas ranges between 55-70%, depending waste(water) composition, and cannot be applied directly for high grade applications such as gas grid injection or vehicle fuel. Conventional...

From the lab to the land, a Bio-Socket to bring electricity to the BoP

In many developing countries governments are not able to provide energy access to its inhabitants, especially those living in rural areas and with the lowest incomes. For these 4-5 million people around the world, who live with less than $2 a day, often referred to as the Base of the Pyramid (BoP), electricity is deficient and unreliable....

A User Friendly Biogas Socket for the BoP: A case study for TNO in Rwanda

This master thesis is carried out for independent research organisation TNO, who initiated the Biogas Socket project in 2008. The Biogas Socket project is part of TNO’s ‘Innovation for Development programme’, wherein high tech development and low-tech innovations contribute to stimulate economic growth and prosperity in BoP countries. This...

An Analysis-of-Options approach to comprehend decision making in the Dutch biogas system

Gas is essential to the functioning of the Dutch energy system, as it covers nearly half of the total primary energy supply in the Netherlands. Biogas obtained by the digestion of wet biomass may become a growing source of green energy for the Netherlands. The Dutch ministry of Economic Affairs, Agriculture and Innovation (EL&I) considers biogas...

Strategic Niche Management of Biogas technologies in the Netherlands

Acoustic design and scaling aspects of a photoacoustic sensor system for combustible gases

Nowadays most of the energy needed comes from fossil fuels such as natural gas (NG). Dwindling stocks of all fossil fuels, including locally occurring natural gas reservoirs, have spurred the effort to both decrease dependence on local fuels and switch to renewable, green energy. The drawback to gas sources like Subsitute Natural Gas (SNG),...

Compost, biogas and biochar in Northern Ghana: Climate impact and economic feasibility in the context of voluntary carbon markets

The Master’s programme Industrial Ecology is jointly organised by Leiden University and Delft University of Technology. In some areas of Sub-Saharan Africa appropriate organic waste management technology could address development issues such as soil degradation, unemployment and energy scarcity, while at the same time providing climate benefits....

The emergence of biogas infrastructures in The Netherlands

Due to increasing energy dependencies, environmental concerns and European directives on sustainability, The Netherlands is increasing its share in renewable energy production. This has led to the definition of several energy ambitions. An example is related to green gas, with the ambition of green gas substituting 50% of the natural gas supply...

The Methanizer: A Small Scale Biogas Reactor for a Restaurant

The purpose of this study is to determine the technical and economic feasibility of a smallscale bioreactor called the Methanizer for a restaurant. The bioreactor converts organic waste produced by the restaurant into methane. This methane can be used to power the restaurant’s cooking stoves. The system proposed is a double-tank, batch-fed...

A Strategy to Automate the Monitoring Process of Small Scale CDM Biogas Projects

This project was carried out in cooperation with TNO for ICCO and Fair Climate Fund (FCF). ICCO and FCF approached TNO to help them develop a low cost automated monitoring system to simplify and standardise the labour intensive monitoring process followed by one of their partner NGO in India. Currently the cost for periodic monitoring of small...
