Climate　change　has　attracted　global　attention,　highlighting　the　critical　role　of　low-carbon　technologies　in　addressing　environmental　challenges.　Due　to　the　multidisciplinary　nature,　complexity,　and　diversity　of　research　content　on　low-carbon　technologies,　a　comprehensive　overview　is　still　limited.　This　paper　uses　bibliometrics　analysis　to　discuss　the　research　status　and　hotspots　of　low-carbon　technology　from　a　macro-perspective.　The　LDA2Vec　topic　recognition　model　is　adopted　to　identify　key　technical　terms,　and　CiteSpace　software　6.3.1　Advanced　Edition　is　used　to　conduct　in-depth　analysis　of　the　development　trajectory　of　low-carbon　technology.　After　checking　the　frequency　of　the　relevant　keywords,　four　key　techniques　were　identified.　In　order　to　further　analyze　the　research　results,　the　learning　curve　theory　is　used　to　predict　the　cost　development　trend　of　key　low-carbon　technologies.　The　results　show　that:　(i)　low-carbon　technologies　play　a　key　role　in　the　energy　sector　and　have　a　potential　impact　on　policy　making,　and　the　cost　of　related　technologies　will　be　significantly　reduced　in　the　next　few　years.　(ii)　Global　low-carbon　technologies　have　entered　an　important　period　of　development,　but　remaining　challenges　need　to　be　addressed　by　optimizing　technological　performance.　(iii)　It　is　very　important　to　strengthen　the　research　on　hydrogen　production　technology　and　photovoltaic　power　generation　technology;　the　cost　reduction　in　hydrogen　production　technology　is　still　significant　and　there　is　room　for　further　optimization.　(iv)　To　effectively　address　the　high　costs　and　technical　barriers　associated　with　emerging　low-carbon　technologies,　increased　funding　for　research　and　development　is　critical.
