“…It is also a potential option to decrease the use of fossil fuels for power generation [50][51][52][53]. Biogas plants can be fed by several potential sources, including organic municipal waste, food waste, sewage as an individual feedstock source or a co-digestion process where a combination of more than one source can yield a higher biogas volume [54,55]. Potential feedstock to generate biogas in Malaysia include Municipal Solid Waste (MSW) [56], food waste, cattle manure, sewage and the most established waste product for biogas in Malaysia, which is palm oil mill effluent (POME) [57][58][59][60][61][62][63][64].…”

The Malaysian Government has set an ambitious target to achieve a higher penetration of Renewable Energy (RE) in the Malaysian energy mix. To date, Malaysia has approximately 2% of its energy coming from RE generation sources compared to the total generation mix and targets achieving 20% penetration by 2025. The current energy mix for Malaysia power generation is mainly provided by natural gas and coal. The discussion will cover the traditional sources of generation including natural gas, coal and big hydro stations. In addition, the paper will cover in depth the potential of RE in the country, challenges, and opportunities in this sector. This study can give an initial evaluation of the Malaysian energy industry, especially for RE and can initiate further research and development in this area in order to support the Government target to achieve RE target of 20% by 2025.

“…As for biogas, Hengeveld et al [33] proposed a pipeline model connecting multiple biogas digesters and an upgrading and injection facility in order to decrease the production costs and energy used for the production of green gas. Hoo et al [34] studied the injection of upgraded biogas from landfill gas into an existing natural gas pipeline and evaluated scenarios where it is economically and physically viable. Mian et al [35] developed a multi-objective optimization model of SNG production through gasification of algae feedstock.…”

A better design of gas supply chains may lead to a more efficient use of locally available resources, cost savings, higher energy efficiency and lower impact on the environment. In optimizing the supply chain of liquefied natural gas (LNG), compressed natural gas (CNG) or biogas for smaller regions, the task is to find the best supplier and the most efficient way to transport the gas to the customers to cover their demands, including the design of pipeline networks, truck transportation and storage systems. The analysis also has to consider supporting facilities, such as gasification units, truck loading lines and CNG tanking and filling stations. In this work a mathematical model of a gas supply chain is developed, where gas may be supplied by pipeline, as compressed gas in containers or as LNG by tank trucks, with the goal to find the solution that corresponds to lowest overall costs. In order to efficiently solve the combinatorial optimization problem, it is linearized and tacked by mixed integer linear programming. The resulting model is flexible and can easily be adapted to tackle local supply chain problems with multiple gas sources and distributed consumers of very different energy demands. The model is illustrated by applying it on a local gas distribution problem in western Finland. The dependence of the optimal supply chain on the conditions is demonstrated by a sensitivity analysis, which reveals how the model can be used to evaluate different aspects of the resulting supply chains.

Line‐pack storage in biogas infrastructures at regional scale, a model approach

et al. 2019

Summary Previously, we reported on a biogas transport model; the model assesses transport costs in a grid with fishbone and star layout collecting biogas. Biogas collection from several digesters to a hub supports the efficient use of resources. A dedicated grid, used for transport, can serve as a form of biogas storage as well. So a model was developed to evaluate line‐pack storage in a transport grid for different digester scale, number of digesters, region size, and grid type. Line‐pack storage does not require additional investments, and variable costs consist of extra compression costs. In both fishbone lay‐out and star lay‐out estimated line‐pack storage, costs are between 0.3 and 1.5 €ct m‐3h‐1. In a star lay‐out, line‐pack storage volume increases with region size. In a fishbone lay‐out, the maximum line‐pack storage volume is small in both a small size region and in a large region, as a result of pipeline volume and pressure restriction. A comparison of storage costs shows that line‐pack storage can compete on costs with pressureless storage, but pressurized pipes are preferred for seasonal storage. A method to describe enlargement of line‐pack storage by increased investment in pipelines depending on maximum transport pressure is presented. Such enlargement by applying larger pipe diameters could be financially sensible.
