Bahan bakar karbon netral

Bahan bakar karbon netral adalah bahan bakar energi atau sistem energi yang tidak memiliki emisi gas rumah kaca bersih atau jejak karbon. Salah satu kelasnya adalah bahan bakar sintetis (termasuk metana, bensin^[1]^[2], bahan bakar diesel, bahan bakar jet atau amonia)^[3] yang dihasilkan dari energi terbarukan, berkelanutan atau nuklir yang digunakan untuk menghidrogenasi karbon dioksida yang ditangkap langsung dari udara (DAC), didaur ulang dari emisi gas buang cerobong pembangkit listrik atau berasal dari asam karbonat dalam air laut. Sumber-sumber energi terbarukan termasuk turbin angin, panel surya, dan pembangkit listrik tenaga air.^[4]^[5]^[6]^[7] Jenis sumber energi terbarukan yang lain adalah bahan bakar hayati.^[8] Bahan bakar seperti itu berpotensi karbon netral karena tidak menghasilkan peningkatan bersih gas rumah kaca di atmosfer.^[9]^[10]^[11]

Sejauh bahan bakar karbon netral menggantikan bahan bakar fosil, atau jika dihasilkan dari limbah karbon atau asam karbonat air laut, dan pembakarannya tunduk pada penangkapan dan penyimpanan karbon di pipa buang atau knalpot, mereka menghasilkan emisi karbon dioksida negatif dan pembersihan karbon dioksida neto dari atmosfer, dan dengan demikian merupakan bentuk pembersihan gas rumah kaca.^[12]^[13]^[14]^[15]

Karbon netral tenaga menjadi gas seperti itu dan bahan bakar karbon negatif dapat diproduksi melalui elektrolisis air untuk menghasilkan hidrogen yang digunakan dalam reaksi Sabatier untuk menghasilkan metana yang kemudian dapat disimpan untuk dibakar kemudian dalam pembangkit listrik sebagai gas alam sintetis, diangkut melalui jalur pipa, truk, atau kapal tanker, atau digunakan dalam proses gas menjadi cairan seperti proses Fischer-Tropsch untuk menghasilkan bahan bakar tradisional untuk transportasi atau pemanasan.^[16]^[17]^[18]

Pabrik metana sintetis 250 kilowatt telah dibangun di Jerman dan sedang ditingkatkan hingga 10 megawatt.^[19]

Produksi

Bahan bakar karbon netral merupakan hidrokarbon sintetis. Mereka dapat diproduksi dalam reaksi-reaksi kimia antara karbon dioksida, yang dapat ditangkap dari pembangkit listrik atau udara, dan hidrogen, yang dihasilkan melalui elektrolisis air menggunakan energi terbarukan. Bahan bakar ini, sering disebut sebagai bahan bakar elektro, menyimpan energi yang digunakan dalam produksi hidrogen.^[20] Batu bara juga dapat digunakan untuk menghasilkan hidrogen, tetapi batu bara bukan merupakan sumber karbon netral. Karbon dioksida dapat ditangkap dan dikubur, menjadi bahan bakar fosil karbon netral, meskipun tidak terbarukan. Penangkapan karbon dari gas buang dapat membuat bahan bakar karbon netral menjadi negatif. Hidrokarbon lain dapat diuraikan untuk menghasilkan hidrogen dan karbon dioksida yang kemudian dapat disimpan, sementara hidrogen digunakan untuk energi atau bahan bakar, yang juga merupakan karbon netral.^[21]
