Hawaii

The intermittent nature of renewable energy is a well-documented thorn in the side of efforts to decarbonize the power grid, especially with more wind and solar generation coming online every year. But while those sources of clean energy are not available all the time, it’s also true that they can sometimes produce more power than transmission lines or a power grid can handle during other periods, leading to curtailments. An increasingly important tool that can lessen the impact of both problems is power storage. In today’s RBN blog, we’ll address the limitations of today’s storage options and look at how long-duration energy storage (LDES) could play a critical role in the years ahead.

We’ve spent a lot of time this year looking at the global move to decarbonize and explaining why there isn’t going to be a straight line leading directly to abundant carbon-free power and a net-zero world. That might be the way a lot of people would like to see it go, but that’s not the reality we’re now facing. All sorts of obstacles have popped up, indicating that the energy industry’s trilemma of availability, reliability and affordability not only clash with each other on occasion, they can also conflict with economic and environmental priorities. Nowhere is that more evident than in the U.S., where small-scale battles over the clean-energy transition are playing out all over the map. In today’s RBN blog, we discuss highlights from our newly released Drill Down Report on the ways the nation’s clean-energy push is playing out at the state level. 

It has become abundantly clear over the past couple of years that energy transition isn’t going to be a straight line leading directly to abundant carbon-free power and a net-zero world. All sorts of obstacles have popped up, indicating that the energy industry’s trilemma of availability, reliability and affordability not only clash with each other, they can also conflict with environmental priorities. The challenge is being felt now in Hawaii, where a commitment to expanding energy production from renewable sources and tamping down the use of fossil fuels while also keeping prices under control and reducing pollution is turning out to be no easy feat. In today’s RBN blog, we look at Hawaii’s recent efforts to phase out coal- and oil-fired power generation, why that’s turned out to be easier said than done, and what it all means for environmental performance and energy prices.

Today is a sad day for the world of oil tankers. Unless a miracle happens by 10 a.m. local time at the Hawaii Department of Transportation's Harbors Division, the last surviving iron-hulled, sail-driven oil tanker is headed to Davy Jones’ Locker. The once-proud, four-masted, 143-year-old windjammer will soon be scuttled by deliberately sinking her at sea off the shores of Honolulu. How could things have come to this? In today’s blog, we’ll take a trip down memory lane to explore how a spectacular, fully rigged oil tanker could have survived for so long, plying the oceans for this author’s former employer, only to be betrayed in her final years.

It’s been two years since Hawaii’s electric and natural gas utilities made their first, tentative moves toward ending their dependence on crude oil (for power generation and the production of synthetic natural gas) by shipping in liquefied natural gas (LNG) from western Canada and the U.S. mainland. While Hawaii Gas has secured state regulatory approval to ramp up the number of LNG-filled ISO containers it receives, the gas utility and Hawaiian Electric have so far failed to agree on a comprehensive LNG plan. Also, some state officials remain concerned that simply replacing oil with LNG will undermine Hawaii’s plan to get all its electricity from renewable sources by 2045. Today, we provide an update of the Aloha State’s fits-and-starts transition to LNG.

Only a few months ago, it seemed likely that Hawaii’s electric and gas utilities would wean themselves off crude oil and naphtha-based gas in favor of liquefied natural gas (LNG). Now though, with oil prices low—and expected by many to stay low—the Aloha State’s governor says that he thinks the planned shift to LNG would be too costly and that he’ll fight it. The utilities still see LNG as the way to go, pointing to falling LNG prices and natural gas’s environmental benefits over oil. Today, we consider how lower prices for crude oil and LNG are affecting the debate about Hawaii’s energy future.

It seems increasingly likely that Hawaii’s electric utility and gas utility will be leading the Aloha State through a multi-year transition from an oil-based economy to one founded largely on liquefied natural gas—most of it sourced from Western Canada. Hawaii Gas, which currently makes syngas from naphtha, has proposed a two-step transition to LNG that begins with ISO container shipments and follows up with bulk shipments. That meshes well with Hawaiian Electric’s plan—also a two-stepper. Today, we up update our recent series on Hawaii’s big-wave move to LNG-based natural gas.

Hawaiian Electric’s plan to shift quickly from oil to liquefied natural gas (LNG) based natural gas as its primary power plant fuel is ambitious, but is it broad enough to benefit from the economies of scale that a more comprehensive, state-wide LNG program might provide? Hawaii Gas, which distributes synthetic natural gas it produces from naphtha, wants to shift to LNG as its gas source too, and state policymakers and environmentalists are interested in transitioning a significant part of the transportation sector from gasoline and diesel to natural gas. Will Hawaii become an island paradise for LNG suppliers? In this final episode of our Blue Hawaii series, we consider Hawaii Gas’s LNG plans, and assess the potential for an economy-wide shift to natural gas in the Aloha State.

Hawaii is unique among the states. Not only is it a group of islands hours by plane from the US mainland, it alone—unlike the Lower 48 and Alaska—has neither indigenous oil or natural gas of its own nor any pipeline connections. That leaves Hawaii with no choice but to bring in via ship whatever energy it cannot wring from the sun, the wind or the earth (as in geothermal). After decades of burning oil to generate most of its electricity and making synthetic natural gas from naphtha, the state’s electric and gas utilities are moving toward liquefied natural gas (LNG). Today, we continue our examination of the Aloha State’s energy future with a detailed look at Hawaiian Electric’s plan to quickly shift from oil to LNG.

Hawaii’s electric and gas utilities plan to end their long-time reliance on oil and its by-products—gas on the islands is actually synthesized from naphtha—and to shift to LNG as their primary fossil fuel (in the case of Hawaiian Electric) or at least as a back-up fuel (in the case of Hawaii Gas). The key drivers are economy and environment, but there also has been a worry that one or both of Hawaii’s two oil refineries may shut down, leaving islanders “at sea” from a fuel-supply perspective. Today, we begin a look at the potentially rapid transition to LNG being planned in the Aloha state, and the significant challenges and costs involved in making the switch.
