Native speak here Semicolons in general aren't used much but when they used they combine two independent clauses together without the use of a conjunction provided the two independent clauses relate to each other. ex. 'I take my dog on a walk everyday; she really enjoys them.' You can also use them for list that have extra information and/or lists that need to be broken up more with commas. ex 'I bought some things at the store; a bunch of green bananas, fresh apples, and a lovely pineapple. Where in comparison 'I bought some things at the store, bananas, apples and pineapples.' Without the extra information the semicolon is not necessary "From the results we found that the lowest levelized cost of energy was achieved by dividing the transportation sector in to three technologies; 50% electric, 30% hydrogen and 20% methanol." Because this sentence has the percentages involved a semicolon would be completely acceptable, again semicolons in general aren't used much so use them so use them sparingly. Hope this helps
