Host park's Historic Timeline & Major Milestones

Trace the significant milestones and transformative events in HOST Park's remarkable journey, highlighting its evolution and impact in this insightful timeline.


HOST Park coastline

Pre-HOST Park

The area was once the site of a very large fishpond, Pā’aiea Pond, rumored to be 3.5 miles long and 1.5 miles wide. The pond, immortalized in the Hawaiian proverb “O na hoku o ka lani, o Pā‘aiea ko lalo – The stars are above, Pā‘aiea below”, was covered by a pahoehoe lava flow in 1801.


NELHA Office historical


Natural Energy Laboratory of Hawaii, operated by University of Hawaii was established as a response to the first oil crisis.


EIS for NELH completed.


Mini-OTEC was anchored offshore of Keāhole Point, demonstrating the world’s first production of net electrical power via closed-cycle OTEC.


OTEC pipe historical


Laboratory facilities and its first pipeline to draw deep seawater from 2,000 ft and surface seawater from 45 ft. depths were completed.


Legislation authorized commercial activities, allowing the Laboratory to host new business ventures.


Supplemental EIS to include HOST Park activities completed.


HOST Park was created on 500+ acres and operated by HTDC. US DOE and HOST Park combined resources to install 40” deep and 28”surface seawater system at Keāhole Point. Lab building AC system converted deep seawater cooling.


Master Plan completed.


HOST Park aquaculture ponds


NELH, operated by UH and HOST Park, operated by HTDC merge to become the Natural Energy Laboratory of Hawaii Authority (NELHA).


Additional EIS work and stretegic plan completed.


Micro-tunneling begins to construct two 66” diameter tunnels under the shoreline and offshore reef as a pipeline protection crossing in preparation for NELHA’s new 55” warm and cold seawater pipelines.


HOST Park Gateway Center


Successful deployment of 55” pipeline offshore and construction of initial phase of onshore pump station using specially designed fiberglass reinforced intake canisters. First deep seawater desalination project begins for bottled drinking water.


NELHA tenant count reaches 34.


Construction of Hawaii Gateway Distribution Energy Center completed.


Cellana, in partnership with Royal Dutch Shell, begin construction of a 6-acre micro-algae to biofuels research center.


HOST Park Hale Iako aerial


Master Plan updated. Makai Ocean Engineering completes construction of corrosion lab and heat exchanger test tower to investigate the use of aluminum alloys for OTEC.


August 2015 saw the opening of a modest but functional ocean thermal energy conversion (OTEC) plant in Hawaii. The 100-kilowatt research and development facility became operational, marking the first instance of a closed-cycle OTEC plant being connected to the American grid.


Hale Iako Incubator Building opens, providing office, collaboration and conference space along with business development programs.


Kahilihili St built to provide a frontage road to the park and open up 80 acres. Kicked off Aquaculture Accelerator project with strategic partnerships with HSDC, UH and UH Ventures LLC to market Hawaii’s global visibility in marine aquaculture and capitalize commercial opportunities available.


HOST Park technology incubator


FEMA approved request for $3.447 million from damages to the Puna Geothermal plant and successfully secured $3 million from 11 insurance companies involved in the lava damage.


HOST Park and its businesses weather COVID proving the sector’s resilience as no businesses closed and many new projects started during the pandemic. Tenant count reaches 56.


Mauka Research Campus purchased to provide space for new projects.

2030s +

HOST Park expansion

2030 & Beyond

Plans for HOST Park include the buildout of an Innovation village, a sustainability mall with a research inn, and new roads to open remote areas within the park.
