Trosolwg
Rwy'n Beiriannydd Siartredig gyda 30 mlynedd o brofiad fel Peiriannydd Mecanyddol. Dros y 18 mlynedd diwethaf rwyf wedi cael y fraint o reoli un o labordai oddi ar y safle ar raddfa fawr 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 ein dealltwriaeth o hydrogen ac amonia ymhellach 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, drwy ddefnyddio tanwydd di-garbon fel hydrogen ac amonia. Mae fy ymchwil yn alinio targedau Sero Net 2050 Llywodraeth y DU.
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 2002 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 cydweithrediad diwydiannol.
Yn ystod y cyfnod hwn llwyddais:
- Achrededig UKAS, trosiant o £100k, Gwasanaeth Profi Ynni Solar (SETS)
- Rhaglen 3M yr UE POWERFLAM2, sy'n cynnwys 12 partner Ewropeaidd sy'n ymwneud â chyd-losgi glo â biomas a chynhyrchion gwastraff
Ennill tair gwobr Rhwydwaith Arloesi Caerdydd yn olynol am gydweithio cyfnod cynnar:
- 2003 – Modelu cyfrifiadurol i optimeiddio cyfnewidydd gwres peiriant prosesu gwastraff bwyd ar gyfer ITT Ltd.
- 2004 – Modelu cyfrifiadurol i wneud y gorau o 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 gwerth £7.9M ERDF i sefydlu Canolfan Ymchwil Tyrbinau Nwy Prifysgol Caerdydd (GTRC) a chefais fy mhenodi'n rheolwr yn 2006.
Fe wnes i reoli gosod a chomisiynu cyfleuster GTRC, prosiect gwerth £7.9M ac ar ôl dechrau ar waith, roeddwn yn cadw rheolaeth ar gyllid GTRC (Trosiant oddeutu £1M) a'r cyfrifoldeb o reoli personél GTRC a rhaglenni profi.
Dros y 18 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 ymwneud â sawl prosiect ymchwil i ddatblygu ein dealltwriaeth o hydrogen ac amonia ar gyfer cymwysiadau gwres a phŵer ymhellach.
