Abstract

Tingginya jumlah sumber daya dan cadangan batubara kalori rendah, perlu untuk ditingkatkan pemanfaatannya. Penyediaan energi sampai dengan tahun 2050 diperkirakan tetap didominasi oleh energi fosil. Energi fosil yang tumbuh paling pesat adalah batubara karena sektor pembangkit listrik didominasi oleh PLTU batubara. Sebagai salah satu upaya untuk memanfaatkan batubara nilai kalori rendah yang mempunyai harga energi yang relatif lebih murah, maka dapat dilakukan alternatif pemanfaatan batubara tersebut dengan metode coal blending, coal switching, ataupun coal drying pada PLTU. Coal blending merupakan cara terbaik untuk mengatasi masalah ketersediaan batubara dan ketergantungan terhadap satu sumber pemasok batubara untuk PLTU di Indonesia. Dengan mengganti batubara menjadi kalori yang lebih rendah (coal switching) memang akan menaikkan jumlah konsumsi batu bara, namun karena harganya lebih murah, maka masih didapat penghematan secara finansial. Coal drying dapat menjadi salah satu alternatif untuk memperbaiki kualitas batubara yang mempunyai kandungan moisture tinggi, sehingga batubara tersebut dapat digunakan untuk bahan bakar PLTU eksisting.
