Abstract

Perkembangan teknologi sel bahan bakar dewasa ini telah mendorong peningkatan penggunaan hidrogen sebagai media penyimpan energi (energy carrier) dalam skala besar (hydrogen economy). Hidrogen merupakan media penyimpan energi yang ideal bila dibangkitkan dari sumber energi terbarukan, dan penghubung dalam rantai energi yang berkelanjutan dan bebas emisi dari awal hingga akhir. Penggunaan hidrogen sebagai energi dalam skala besar, hanya mungkin, jika tersedia infrastruktur yang meliputi produksi, penyimpanan, transportasi, dan pengguna akhir yang handal, aman, memadai, dan ekonomis. Saat ini produksi hidrogen dengan teknologi reformasi dari energi fosil merupakan solusi terbaik bagi Indonesia yang memiliki potensi gas alam yang melimpah. Hidrogen selanjutnya disimpan dan didistribusikan dalam bentuk gas dalam tabung yang dikompresi dengan memperhatikan standar yang direkomendasikan untuk hidrogen.

Abstract

Increasing scarcity of fossil fuels makes the deployment of hydrogen in combination with renewable energy sources or the utilization of electricity from full time operation of existing power stations an interesting alternative. A pre-requisite is, however, the safety of the required infrastructure is investigated and its design is evaluated with the associated risk to know, at least, the risks are not higher than that of existing supplies.  Therefore, a risk analysis considering its most important objects such as storage tanks, filling stations, vehicles as well as heating and electricity supplies for residential buildings was carried out. The last is considered as representative of the entire infrastructure. The risk analysis is based on fault and event tree analyses, wherever required, and consequence calculations using the PHAST code. The procedure for evaluating the risk and corresponding results will be presented taking one of the objects as an example.

Abstract

This paper presents an energy saving study result conducted in a sugar factory located in the East Java of Indonesia. Formerly, the sugar factory was designed to fulfil their energy demand by using an abundance free energy sources, called “baggase”. However, a fossil fuel consumption (i.e. residue) increased sharply to supply boilers due to the baggase availability was not sufficient. It impacted to the increasing of operational costs. Therefore, an energy saving study for the factory had been an interesting subject. The study proposed to assess boilers performance in the factory to reduce residue consumption. A detail energy audit method was conducted to identify the actual energy consumption, energy losses, and energy saving potential. The study results showed that energy saving potential for the boilers was about 11%. The main energy saving measures was to increase boilers efficiency from 64% to 75%. The study report also included with repairing recommendation for the boilers as well as its techno-economic analysis.
