A carbohydrate is not a simple organic structure, the synthesis of molecules like that is quite complicated, and involves a lot of inefficiencies and filtering out of by-products.
Chemical fuels like methane or ethane are far simpler, and just inputting energy and synthesising them from basic building blocks is difficult to do cheaply and at scale.
