Nā Manaʻo Palekana & Kaiapuni
- Huhū:He mea hoʻonāukiuki ka PA i ka ʻili, nā maka, a me ka ʻōnaehana hanu. Pono e ʻaʻahu ʻia nā mea pale kūpono (e laʻa, nā mīkina lima, nā maka aniani, nā respirator) i ka wā e lawelawe ai.
- Hiki i ke ahi:Hiki ke puhi ʻia akā ʻaʻole hiki ke wela loa. E mālama i nā lapalapa ahi a me nā wela kiʻekiʻe.
- Ka hopena o ke kaiapuni:E hoʻolei i nā mea ʻōpala e like me nā lula kaiapuni kūloko e pale ai i ka haumia.
Kāhea iā mā˚ou
No ka 'ike hou aku a i 'ole e noi i kekahi la'ana, e 'olu'olu e leka uila i kā mākou hui kū'ai. Kūpaʻa mākou i ka hāʻawi ʻana i nā huahana kiʻekiʻe a me ka lawelawe maikaʻi loa!

Methanol Product Introduction
Nānā Huahana
ʻO ka Methanol (CH₃OH) he wai waihoʻoluʻu ʻole me ka ʻala ʻala ʻala. E like me ka mea ʻona maʻalahi loa, hoʻohana nui ʻia i nā ʻoihana kemika, ikehu, a me nā lāʻau lapaʻau. Hiki ke hana ʻia mai nā wahie mōʻalihaʻi (e laʻa, ke kinoea maoli, lanahu) a i ʻole nā kumuwaiwai hou (e laʻa, biomass, hydrogen ʻōmaʻomaʻo + CO₂), e lilo ia i mea hoʻoikaika nui o ka hoʻololi kalapona haʻahaʻa.
Nā ʻano huahana
- ʻO ke ahi wela kiʻekiʻe: ke ahi maʻemaʻe me ka waiwai calorific haʻahaʻa a me nā haʻahaʻa haʻahaʻa.
- ʻO ka mālama maʻalahi a me ka lawe ʻana: ʻO ka wai ma ka lumi wela, ʻoi aku ka scalable ma mua o ka hydrogen.
- Versatility: Hoʻohana ʻia ma ke ʻano he wahie a me ka meaʻai kemika.
- Hoʻomau: Hiki i ka "Green methanol" ke hoʻokō i ke kūpaʻa kalapona.
