Mr Steven Morris
Staff Rheoli, Proffesiynol ac Arbenigol
Trosolwyg
Rwy'n Beiriannydd Siartredig gyda 28 mlynedd o brofiad fel Peiriannydd Mecanyddol. Dros yr 17 mlynedd diwethaf rwyf wedi cael y fraint o reoli un o labordai oddi ar y safle Prifysgol Caerdydd o'r enw Canolfan Ymchwil Tyrbinau Nwy (https://cu-gtrc.co.uk).
Mae'r Ganolfan yn parhau i roi heriau ysgogol i mi ac rwyf wedi bod yn ffodus i weithio gydag academyddion ac ymchwilwyr eithriadol ym maes gwres a phŵer carbon isel. Mae'r gwaith cyffrous hwn yn cyrraedd cynulleidfa genedlaethol a byd-eang ac yn mynd i'r afael yn uniongyrchol â'r angen i leihau ein dibyniaeth ar danwydd ffosil i sicrhau dyfodol cynaliadwy i ni a chenedlaethau'r dyfodol.
Ar hyn o bryd rwy'n cymryd rhan mewn sawl prosiect ymchwil i ddatblygu ymhellach ein dealltwriaeth o hydrogen ac amonia ar gyfer cymwysiadau gwres a phŵer.

Ymchwil
Fy niddordeb ymchwil yw datgarboneiddio prosesau gwres a phŵer e.e. llosgwyr, ffwrneisi, peiriannau cilyddol a thyrbinau nwy, trwy ddefnyddio tanwydd di-garbon fel hydrogen ac amonia. Mae fy ymchwil yn cyd-fynd â thargedau Sero Net 2050 Llywodraeth y DU.
Ar hyn o bryd rwy'n gweithio gyda National Gas Transmission ar brosiect FuturGrid
Bywgraffiad
Mae gen i radd anrhydedd dosbarth cyntaf mewn Peirianneg Fecanyddol o Brifysgol Caerfaddon gyda 7 mlynedd o brofiad diwydiannol cyn dechrau gweithio gyda Phrifysgol Caerdydd yn 2001 pan gefais fy mhenodi'n Uwch Beiriannydd Prosiect yn y Ganolfan Ynni, Gwastraff a'r Amgylchedd (CREWE) yn yr Ysgol Peirianneg gyda'r cyfrifoldeb am sefydlu a rheoli cydweithredu diwydiannol.
Yn ystod y cyfnod hwn, llwyddais i reoli:
- UKAS-achrededig, trosiant o £100k, Gwasanaeth Profi Ynni Solar (SETS)
- Rhaglen 3M yr UE POWERFLAM2, sy'n cynnwys 12 o bartneriaid Ewropeaidd sy'n ymwneud â chyd-danio glo gyda biomas a chynhyrchion gwastraff
Enillodd dair gwobr Rhwydwaith Arloesi Caerdydd yn olynol am gydweithrediad cynnar:
- 2003 – Modelu cyfrifiadurol i optimeiddio cyfnewidydd gwres peiriant prosesu gwastraff bwyd ar gyfer ITT Ltd.
- 2004 – Modelu cyfrifiadurol i optimeiddio system atal peiriant golchi domestig ar gyfer Andrew Reason Ltd
- 2005 - Dylunio datrysiad pŵer cynaliadwy ar gyfer bwi gwyliadwriaeth cynnig isel ar gyfer Ledwood Engineering Ltd
Ac yn 2005 cynorthwyais i ddatblygu cais llwyddiannus o £7.9M gan ERDF i sefydlu Canolfan Ymchwil Tyrbinau Nwy Prifysgol Caerdydd (GTRC) a chefais fy mhenodi'n rheolwr arni yn 2006.
Roeddwn i'n rheoli gosod a chomisiynu cyfleuster GTRC, prosiect gwerth £7.9M ac unwaith i fyny a rhedeg roeddwn yn rheoli cyllid GTRC (Trosiant tua £1M) a chyfrifoldeb am reoli personél GTRC a rhaglenni prawf.
Dros yr 17 mlynedd diwethaf rwyf wedi cael y fraint o reoli'r GTRC, un o labordai oddi ar y safle ar raddfa fawr Prifysgol Caerdydd (https://cu-gtrc.co.uk).
Mae'r Ganolfan yn parhau i roi heriau ysgogol i mi ac rwyf wedi bod yn ffodus i weithio gydag academyddion ac ymchwilwyr eithriadol ym maes gwres a phŵer carbon isel. Mae'r gwaith cyffrous hwn yn cyrraedd cynulleidfa genedlaethol a byd-eang ac yn mynd i'r afael yn uniongyrchol â'r angen i leihau ein dibyniaeth ar danwydd ffosil i sicrhau dyfodol cynaliadwy i ni a chenedlaethau'r dyfodol.
Ar hyn o bryd rwy'n cymryd rhan mewn sawl prosiect ymchwil i ddatblygu ymhellach ein dealltwriaeth o hydrogen ac amonia ar gyfer cymwysiadau gwres a phŵer.
