Corporate attempts to match every hour of consumption with renewable production could pave the way for grid decarbonisation
Current power purchase agreement deals only truly do not fully match the demand profile of the customer meaning fossil fuel generation is required to fill the gap
CREDIBILITY GAP Power purchase agreements allow companies to say they are carbon free when that is not the case
HOURLY MATCHING A better approach is to match generation and demand by the hour—but it is hard to achieve in practice
KEY QUOTE If you had unlimited financial means, you could easily solve this ...

Five years ago, technologists excitedly started suggesting how to use blockchain for energy applications and a raft of start-ups followed, sporting distributed ledgers for the power sector. Today, the word "blockchain" is seldom heard in energy circles. While the hype may have been overblown, work continues instead on a quieter revolution to the one that was promised
Case study: The breathless furore around blockchain has died down but in some ways, the technology is still supporting the energy transition. Carbon-conscious buyers and sellers can use a distributed ledger to track where the electricity they use comes from
Time-stamped certificates would allow customers to know where their power is coming from at any given time and could provide another signal for investors by driving up prices for green energy certificates when supply is short. Regulators are taking steps to ensure that consumers signing up for green tariffs are really helping to progress the energy transition
Once regarded as a high risk gamble, buying green electricity directly from generators under a mutually agreed power purchase agreement (PPA) has become big business in the commercial and industrial sector. City authorities eager to cut their electricity bills and buy renewable are looking to get into the market. The new demand is set to drive big growth in renewables
Electricity networks are buckling under the impact of increasingly frequent and severe climate events. Given the amount of climate change already locked into the atmosphere, this is an issue that will only worsen, forcing assets and infrastructure to adapt. The tools to deal with the problem are available—but it will take a lot of money and political will to avert disaster
Clean energy technology is becoming more efficient and powerful, while more money than ever is seemingly flowing into renewables. But administrative barriers thrown up by red tape and permitting bottlenecks threaten to put a damper on the energy transition
